Anti-glare PC board and preparation process thereof

Abstract

The invention discloses an anti-glare PC board and a preparation process thereof. The anti-glare PC board is prepared from the following raw materials in parts by weight: 50-60 parts of silicate, 80-100 parts of polycarbonate resin, 0.5-0.7 parts of polymethyl methacrylate, 2-6 parts of glass fibers, 0.1-0.3 parts of polystyrene, 0.1-0.2 parts of a silane coupling agent and 2-3 parts of metal oxide. Because silicate is added, strong absorption performance is realized on ultraviolet light and blue light, the transmittance of visible light in other wavelength ranges is relatively high, the anti-dazzle performance is better, there is no impact on viewing, the cost is lower, and the chemical performance is stable. Polystyrene is added and has good acid and alkali resistance, so that the corrosion resistance of the PC board is enhanced, the service life of the PC board is prolonged, and the transparency of the PC board is not influenced. By adding the silane coupling agent, the compatibility of all components in the PC board is enhanced, and the stability of the PC board is improved.

Description

technical field [0001] The invention relates to the technical field of anti-glare PC boards, in particular to an anti-glare PC board and a preparation process thereof. Background technique [0002] PC board is also called polycarbonate board, Capron board. Weak acid resistance, with polycarbonate as the main component, made of co-extrusion technology CO-EXTRUSION, showing that the PC board is resistant to neutral oil, not resistant to strong acid, not durable, not resistant to alkali, it needs to be coated with UV . But high temperature resistance, good lighting effect PC sunshine board (also known as polycarbonate hollow board, glass capron board, PC hollow board) is made of high-performance engineering plastics ----- polycarbonate (PC) resin. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardant, and anti-aging. Building materials have advantages that other building decoration materials (such...

Problems solved by technology

[0003] The application of PC boards in automobiles is very common, but the existing PC boards have poor filtering effect on blue light and ultraviolet light, which can easily cause glare to people. Studies have shown that glare has become one of the main factors causing traffic accidents. Exposure to glare for a long time will damage the driver's body and mind. Car headlights contain a lot of blue light, which is very easy to produce glare when used, and the existing PC board is also low in strength and easily damaged
