Based on the principle of retroreflective, the reflector can illuminate the front with the illumination and reflection of the lamp, and improve the distance between the driver and the object, so that the driver can take more appropriate time to take corresponding safety measures. Compared with other kinds of road traffic safety measures, the application of reverse reflection technology is undoubtedly a cost-effective and effective solution compared with all kinds of costs to reduce road traffic accidents. In a sense, the application of retroreflective material is a more proactive safety precaution. It has more safety value and better care for life. Figure 1, 2 is a picture of a variety of typical applications. From the beginning of 1930s, in addition to the human model quickly put into use a variety of retroreflective materials created by science and technology industry, to reduce road traffic injuries as soon as possible beyond the understanding of reflective, reflective material origin also began to start the study of inverse reflection technology to improve road traffic safety conditions of application!
Reflective materials mainly include reflective film, reflective ink, reflective marking paint, reflective cloth, reflective leather, reflective ribbon, reflective fabric, and so on. The reason why reflective materials can reflect light is that most of the reflective materials contain a high refractive index glass bead. Precisely because of its existence, the incident light is reflected back to the light source on the original path, forming a regressive reflection phenomenon.
At present, the application of reflective materials mainly concentrated in two major markets, is a special plan market, two is the civil Chang plans market has now formed a large scale, the market is a huge potential civil so-called special market, generally refers to the instruction according to the state regulations, must use the reflective material field, such as public security, traffic the sanitation department, staff uniforms, road signs and markings, mine material, reflective material industry investment prospects? The clothing, straps, etc. of the field workers of the railway and so on. Reflective film, reflective marking paint, reflective paint, reflective safety silk fabric is mainly used in this city, which often reflective film in the public transportation sector in China has laws and regulations, according to the standard requirements, reflecting film annual consumption of about 2 million 500 thousand square meters, annual sales will reach 600 million yuan. Reflective coatings include road marking reflective coatings and return to reflective paint. The traditional marking materials (hot melt paint, spray paint, cold) not only need to allocate a lot of manual work, and easy to produce Diaoqi phenomenon, does not have the reflective properties in foggy days, evanescent light irradiation on the ground, barely discernible, while the return reflective coating is in general surface covered with a layer of paint glass beads, which is used not only to overcome the defects, and the driver driving safety is guaranteed. Therefore, the reflective material will become a hot spot of investment in the future.
