Reflective material domestic technology

The localization of the reflective material is three technical aspects of raw materials, equipment and technology. Reflective material used by the major raw materials including resin, pigments, glass beads, the performance impact of any raw material of reflective products are essential. Wherein the adhesive resin must have good workability, excellent bonding ability, if the item is no protective layer on the surface of the adhesive resin also require water resistance, washability, surface resin in claim good transparency, ideal refractive index, excellent weathering resistance and stability between the layers of resin also must have good matches the optical characteristics of reflective material products so as to meet requirements, the use requirements and manufacturing process requirements; high transparency of the pigment is required , hue stability, good compatibility with a resin. For glass beads, the requirements of having a high refractive index, high transparency, low devitrification rate, good roundness, good particle size uniformity and dispersibility. In recent years, the national development of new materials research to increase support for efforts to an endless stream of new material, as well as factory to enter the foreign large-scale chemical enterprise, the problem of raw materials required by the reflective material has basically been resolved. Production equipment is the basis of reflective materials industry, the selection of equipment of different reflective material products of the same, according to the characteristics of the product process, process requirements, as well as the raw materials used, select the appropriate device configuration precision operation way to determine a reasonable device structure. To be considered to meet the requirements of production technology to achieve the minimum equipment investment. The various processes of the the existing reflective material equipment configuration is reasonable, they use a computer closed-loop feedback, frequency synchronous operation control, constant tension control, subregional adjustable temperature control, frequency conversion constant pressure techniques, equipment operation and stability, coating drying ability, quality control is more stable, but the degree of automation of the device to be further improved. Production process and raw materials, production equipment complement each other, inextricably linked, in sulfur given the design of raw materials, to consider whether or not to meet the production process requirements, and determine the production process should be, as far as possible, does not change the raw materials, to seek can be implemented easiest, most reliable technology, the production line according to the different production processes, using a variety of coating methods, making different kinds, different properties of the coating can achieve micron-level precision controllable coating, can guarantee full The format of the coating uniformity. And on the device through a unique design solution process plant beads, operability, simple and practical, technical problems solved glass micro-glass beads monolayer surface implanted. The technological level of domestic products basically reached the level of foreign products, and some products even more than foreign products, production processes more streamlined.

Standard two to five reflective material, reflective material of glass beads through habitat type in the country has formed a complete industrial chain, in a micro-prism reflective film reflective film world, only 3M, Avery, etc. reflective materials to master the core technology, this project has just entered the stage of research and development, micro-prism reflective material capable of producing reflective lattice film is used for civilian use and less demanding traffic.
