What Is The Most Reflective Material, China’s reflective safety materials

What Is The Most Reflective Material? Directional reflective material is a combination of inorganic and organic. It is a new type of optical functional material composed of high refractive index glass beads, reflective material layer, weather resistant polymer resin and high strength adhesives. It is widely used in roads, railways, ports, marine transportation, mines, tunnels, fire protection, urban construction and other fields as various signs, warning signs, vehicle license plates, lifesaving appliances, etc.

Definition, performance and utilization value of reflective materials

How Does Retro Reflective Material Work: Due to the characteristics of retroreflective material and strong regressive reflection effect, the retroreflective reflection phenomenon occurs when the incident light is reflected by the original path. Road traffic safety: No power supply is needed so that it can obviously improve the safety and reliability of the user and reduce the probability of accident. An international statistics show that the probability of traffic and road marking related to accidents is 70%, which can increase the transport efficiency by 30%. The clear and complete traffic and road signs give the driver and pedestrians a good reflection effect, which can effectively reduce the accident and improve the driving efficiency. According to the statistics of relevant departments in China, 81562 traffic accidents occurred at night in the country in 1996. 2535 people died, accounting for 28.3% of the number of traffic accidents in the whole year. Under the condition of no lighting, we should use reflective materials to set up the traffic signs, signs, vehicle license plates or clothes and decorations with reflective materials. This will reduce the traffic accident rate by 30%~40%. In 1998, 601471 people died of traffic accidents in the world’s major countries. There were only 78067 people in China, the first in the world. According to the comprehensive analysis, the incidence of traffic accidents in major cities is significantly higher than that in the daytime. The accident peak is concentrated at 8 to 10 o’clock in the evening. One of the reasons is low visibility. The emergence of reflective materials successfully solved the problem of “seeing” and “be seen” at night.

In 1950, Dr. Dong Qifang, a Chinese American, studied and developed a glass bead directional reflective film. In 1968, the ROWLAND brothers of the United States invented and patented the reverse reflective technology of the microprism. The warning signs made with a reflective film are hundreds of times more visible than other non-reflective materials in the light. Under the light of a car headlight, the driver can find the target within a distance of about 800 meters ~1000 meters under the light of the car’s headlight, which is 0.5 meters in diameter. Reflective film has been widely applied in foreign transportation facilities and personal safety facilities. Even the standardized use of reflective materials is one of the important bases for insurance compensation in western developed countries such as the US. At first, the main production enterprises with glass beads as the characteristics of American 3M Company and products for the characteristics of the micro prism America Reflexite Company.

The directional reflective characteristics of reflective materials decide that it will become a safety guarantee for people’s livelihood, effectively reduce the accident rate, improve driving efficiency and eventually become an essential consumable for traffic safety. It is called “small products” to win the “big market”

Two, the development and present situation of Chinese reflective materials

Reflective Material Development Process: China began to contact the reflective materials in 1960s, and the research on the reflective materials began in 1979. In 1984 the United States 3M company. With its abundant capital and advanced technology in the China market. A lot of technology training and promotion, reflective film products are widely used for making Chinese promotion to the government, and processing of traffic signs, the reflective film in China road to wide application.

As early as in 1996, the development and production of the reflective film products in China had already begun. But, after all, the reflective film is a kind of high-tech product with intensive technology, such as optics, polymer physics, micron chemical technology and so on. Because of the difficulty of production technology is larger, production equipment is not complete. The reflective film product quality once stay in a low level, and the requirements of reflective film products and technical standards, large investment, domestic demand for the rigor of the domestic reflective film has been stuck in the “development bottleneck” cannot meet the type. The high quality requirements of high grade highway market. So the reflective film products in our country every year to import about $20 million.

But after nearly ten years of technological exploration and innovation, in recent years, China’s reflective material manufacturers have fully mastered the production process of reflective film, and began to form large-scale production, and more than half of its products are exported to foreign countries, and are widely used.

In recent years, China market into the international market integration and the knowledge economy and the characteristics of informatization to speed up the pace. In the reflective film market demand double pull, the reflective film manufacturers to further increase the scale of production to promote reflective film strength, our reflective film can improve the production and the rapid development of technology research and development.

Three, the quality, classification and value orientation of Chinese reflective materials meet the needs of the development of China’s highway construction

1.The improvement of the structure of the reflective materials produced in China shows that the quality of the material is mature and stable

The main structure of the glass bead reflective material is a glass bead with a diameter of only tens of microns. Because the refractive index of glass is different from that of air. Light is focused on glass beads behind the glass beads. If a reflective surface is placed on the focus, the injected beam can be reflected in the incident direction. The reflective film made of this principle is called a “lens type reflective material”.

The reflective layer of reflective material is generally used for glass beads or silver plated, make the surface protection layer after the vacuum aluminum, the refractive index of 2.25~2.50, Chinese production of glass beads was due to production equipment and technology level is poor, the refractive index is only 1.90~2.00, and the dispersion angle, needs to be improved. Today, almost all the international anti – optical materials, especially a few famous brands, have set up factories in China. And a large number of glass beads produced in China are used as raw materials for their reflective materials, which is enough to show the maturity and stability of the quality of glass beads produced in China.

Secondly, binder is also an important component of reflective materials. The binder mentioned here refers to the raw material that glass beads are bonded with reflective surface. The international binder is mostly used in polyurethane. In the past, the polyurethane produced in China was easily discoloration and embrittlement under the conditions of sun and rain, which resulted in the discoloration of the reflective material for about two years. In recent years, the service life of acrylic pressure sensitive adhesive made in China can last at least three years, which ensures that the performance of reflective film produced in China is basically guaranteed.

Moreover, the properties of the focus resin and the surface protective layer also determine the quality of the reflective film. It must be characterized by high transparency, good oil resistance, UV resistance, flexibility and folding resistance. With the rapid development of international market integration and knowledge economy, China’s production technology has been significantly improved, and the quality of its products is also very stable. Otherwise, how can China’s reflective materials export to other countries over the years?

2. Classification of reflective materials produced in China

The need of rapid economic development. In recent years, the development of China’s highway construction still has a rapid development trend. In addition to improving the national backbone road network, provinces and cities are also gradually establishing the provincial highway network and urban and rural highway system. The development trend of such highway construction determines the cost of different cost of reflective materials for different cost of highway engineering.

Chinese reflective materials to promote quality assurance in the foundation, fully aware of the different security product quality and cost requirements of different traffic environment, reflective traffic safety products must have different quality properties, under appropriate conditions so as to reduce the cost. In order to promote the maximum quantization in China traffic engineering construction.

For example, the WEALLIGHT reflective film products are based on the following categories to meet different needs.

A. acrylic directional reflective film

The reflective film is made of acrylic resin as the reflective film surface layer. Acrylic and acrylic resin. It can be used in silk screen printing, advertising spray painting, construction sign and so on. The operation process is simple and easy to master.

The characteristics of this reflective material are:

(1) Because the glass bead is not covered, the intensity of the reflective light is larger.

(2) The surface gloss is not strong, easy to be torn and flexible;

(3) Good aging resistance.

B. PET directional reflective film

That is to say, the surface is PET surface layer. It belongs to a kind of polyester film. The acrylic membrane pressure sensitive adhesive is coated on the double side vacuum aluminized polyester film, and the glass bead with 1.9 refractive index is adhered. After spraying, a thin layer of polyester is sprayed as protective layer. It can be applied to computer engraving, making signs, simple technology, and can be made by hand.

The advantages of this reflective film are:

(1) Easy to clean, no water, rain does not affect the brightness;

(2) Good aging resistance;

(3) High intensity of reflection;

(4) It is not easy to tear.

The above two structures are categorization. They are further subdivided into three grades of Shun Kang’s economy level, three years, five years and seven years of engineering level, license plate level and high-strength level series. The classification is based on the multi – level classification of the multi – demand of the reflective film products based on the traffic environment and market.

3, the value orientation of Chinese reflective materials

From the perspective of the technical performance of reflective materials, the main function of its products is to achieve the purpose of indication and warning through reflective and eye-catching (i.e. retroreflective). Other such as chromaticity performance, high and low temperature performance, weather resistance and so on can be considered as an auxiliary project. Therefore, from a security point of view, the intensity of reflection is the primary factor affecting the quality of the product. So, how much is the reflective intensity of the reflective material to meet the standard? I think it is best to use different quality reflective materials to meet the needs of different traffic environments. According to different requirements, the reflective film is divided into five levels according to the requirements of the inverse reflection coefficient, that is, diamond grade and high strength grade, super engineering grade, engineering grade and economic grade.

On the basis of guaranteeing the basic quality and performance of reflective intensity, domestic reflective materials also respect the diversified needs of traffic highway construction, subdivide product mask components, adjust product structure, control product cost, and launch the product classification of acrylic, PET and PVC. In keeping with national four (project level), five (economy class) reflective strength requirements of reflective film technology, adjust the warranty period and the introduction of reflective film, reflective film products for three years and five years of professional engineering. At an affordable price to meet the national rural highway network construction in high demand, social returns.
