Personal Safety of Reflective Material Return the reflective material
Reflective materials, also known as retroreflective materials, retroreflective materials, widely used in traffic signs marking, protruding road signs, contours, traffic cones, crash barrels and other road traffic safety facilities, as well as car plate, Fire, railway, water, mining, etc., can be divided into traffic signs reflective material, road marking reflective material, protruding road signs, contours, clothing with reflective materials.
The realization of the retroreflective function of the light is realized by the various reflective materials with the retroreflective properties. Most of these materials are not naturally formed by nature, but rely on the creativity of mankind and invent the new material. Reflective technology brings together a variety of disciplines and technologies in optics, materials science, mathematics, organic chemistry and so on.
Reflective material based on the principle of reverse reflection, can use the lamp irradiation and light reflection, to "light" in front, to improve the driver found the distance of the front object, which can give the driver a more adequate time to take the appropriate safe disposal Measures. Compared with other types of road traffic safety measures, the use of retroreflective technology is undoubtedly a cost-effective and effective solution compared to the cost of mitigating road traffic accident injuries. In a sense, the application of retroreflective material is a more proactive safety precautionary measure that is more secure than the measures aimed at reducing the degree of damage, such as guardrail, after the accident Reflect the love of life. Figures 1 and 2 are photographs of various typical applications. 
Since the 1930s, in addition to the rapid use of a variety of science and technology industry to create a new type of retro-reflective material to reduce road traffic injuries as soon as possible, but also began to gradually start the application of retro-reflective technology to improve road safety conditions Research.
Reflective film is a thin film can be directly applied to the retroreflective material, but also the most widely used as a retroreflective material. In 1937, the world's first reflective film in the United States 3M company was born. This is the starting point for the history of large-scale application of reflective signs. In 1939, in the United States Minnesota road side, for the first time in the open air conditions using a Scotchlite TM reflective film produced signs, since then, opened a series of reflective products for traffic signs of the new era, created a A new traffic safety industry. This year, the US traffic mark national standard (1939 edition of the United States "unified traffic control facilities manual", Manual of United Traffic Control Devices, 1939) formally provides that the use of reflective film manufacturing traffic signs.
Since then, with the chemical industry, especially the development of synthetic resin, various research and development institutions continue to research and innovation, the use of glass beads technology, synthetic resin technology, film technology and coating technology, have developed a series of high-quality anti-reflective products.
