A kind of glass fiber reinforced polycarbonate composition and its preparation method and application

Abstract

The invention relates to a glass fiber reinforced polycarbonate composition and its preparation method and application. The composition includes polycarbonate, ABS, glass fiber, acrylic shell silicone rubber, polyurethane, toughening agent, antioxidant, lubricant and the like. The glass fiber-reinforced polycarbonate composition provided by the present invention improves gloss by adding acrylic shell silicone rubber and polyurethane, and gives the glass fiber-reinforced polycarbonate composition a better matte effect, which can meet the requirements of various processes on gloss. Degree requirements; while maintaining high bending toughness.

Description

technical field [0001] The invention belongs to the field of engineering plastics, and in particular relates to a glass fiber-reinforced polycarbonate composition and a preparation method and application thereof. Background technique [0002] PCABS is a traditional high-performance alloy with beneficial characteristics such as high surface gloss, good toughness, and good processing fluidity. It is used in various fields, especially in the field of engineering plastics technology in the fields of electronics, transportation, and building materials. With the development of the industry, the requirements for materials are getting higher and higher. Reinforce modified polycarbonate and its alloys with glass fibers to endow the material with higher strength, rigidity, high temperature resistance and insulation. It is a widely used modified product that meets the lightweight and thin-wall requirements of various industries. development trend. In addition to high rigidity, high m...

Problems solved by technology

[0008] The above matte technologies all have certain limitations. For example, the addition of fillers will lead to inconsistencies in the continuous phase of the matrix, which will easily cause other properties such as mechanical properties and appearance, especially the hidden danger of weld lines during processing; the addition of a large amount of rubber and epoxy It will greatly affect the fluidity of the resin and reduce the rigidity of the material, thus limiting the application of the material to a certain extent, especially under the industry development trend of thinner walls, the lower fluidity will have greater disadvantages; rely on Mold design has a strong dependence on the processing conditions of the material, and its applicability is not wide
