Problems solved by technology

[0004] PC / PMMA alloy can improve the fluidity and wear resistance of PC, and improve the temperature resistance and mechanical strength of PMMA. However, due to the unsatisfactory compatibility of the two materials, PC and PMMA, their blending will cause delamination (but not Peeling), the surface effect is not good

Abstract

The invention relates to optical diffusing poly carbonate (PC) / polymethyl methacrylate (PMMA) alloy. The optical diffusing PC / PMMA alloy comprises the following components: 50 to 100 parts of PC, 5 to 20 parts of PMMA, 1 to 8 parts of PC and PMMA compatilizer, 0.01 to 2 parts of optical diffusing agent, and 0.3 to 1 part of other aid; by compounding and using the compatilizer, the compatibility between PC and PMMA is improved, continuous production can be realized, and the alloy material is high in mechanical property; by adding the optical diffusing agent, the light-emitting source and the dazzling light source are shielded, and the whole resin can emit soft, attractive and elegant light, so that the aims of light transmitting and non-transparency can be fulfilled; and the optical diffusing PC / PMMA alloy has the soft light-distributing effect, and can be widely applied to the fields of liquid crystal displays and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a light-diffusing PC / PMMA alloy. Background technique [0002] Light-diffusing materials refer to materials that can not only allow light to pass through but also effectively scatter light. It can convert point and line light sources into line and surface light sources, and can be used as surface light source materials for signage, display windows, and projection walls. Wall-mounted uniform light sources and transmissive displays, etc., can also be combined with liquid crystal elements to prepare polymer-dispersed liquid crystal display elements, and can be used as backlight materials for liquid crystal displays. At present, most new light-diffusing materials are produced by the blending method, because this method is very similar to the general polymer blending process, especially for the largest amount of light-diffusing sheets, it can be produced continuously and...
