Brief History of the development of reflective material

In 1950, Chinese-American scientist Dr. Dong Qifang developed directional glass beads, and subsequently developed a reflective material such as reflective fabric, 1968, the United States Rowland brothers invented and registered micro-prism retro-reflective technology. Reflective Sheeting by U.S. company 3M pioneered the development of successful, currently only the United States, Japan, China, South Korea and a few other countries can produce long-term use, reflective film in developed countries, its excellent optical properties and excellent social economic value has been widely recognized and accepted. Again, this also attracted the full attention of the Chinese optical industry and traffic safety many areas of science and technology workers. The 1970s, at the China Institute of Metrology Optical teacher Yang Yonggang, retroreflective film properties of the structural principle, optical characteristics, performance testing and other technical literature to the country, followed by many research institutes, universities have been put on the reflective film series The research and development. Such as: Ministry of Transportation Highway Research Institute, Chinese Academy of Sciences, optical and other research institutes are organized experts and special funds to set up a research group to carry out the research project. These early experts and research staff in the reflective material devoted a lot of effort, achieved some initial results, basically worked out the basic production process principle of reflective material, but under the prevailing conditions, the chemical basis weak industrial, special coatings, glass beads, and other raw materials remain unsolved, but not finalized production equipment, under certain conditions limit the industrialization process of reflective material. Eighties, Zhejiang Taizhou reflective materials started to develop high-refractive index glass beads, and gradually solve the most important raw material for the research and development of reflective film, laid the foundation for the localization of reflective material. After the 1990s, domestic reflective material on the beads through the habitat type has made considerable progress, has developed the advertising grade reflective sheeting, engineering grade reflective film, the beads built-in high-strength grade reflective film reflective material, at the same time reflective cloth, reflective leather, reflective thermal film also launched the end of the 1990s glass beads basically mature products in China. However, another type of reflective material micro-prism reflective material just in its infancy, O about 2012 to the beginning of the twenty-first century by Fujian Jinjiang few do shoe business developed in the cock reflective lattice film the the micro prism of civilian products, after several years of evolution more on the quality of the product has increased, the manufacturers of such products produced in the world is basically the implementation of continuous production.
