Abstract

The invention relates to the technical field of PC materials, and particularly relates to a high-strength modified PC material. Raw materials of the material are calculated by weight and comprise 60-80 parts of PC resin, 4-8 parts of PMMA resin, 5-10 parts of ABS resin, 0.5-2 parts of an organosilicon additive, 2-4 parts of a methyl methacrylate-butadiene-styrene copolymer, 2-4 parts of a flexibilizer, 4-5 parts of an antioxidant, 3-6 parts of a flame retardant, 0.5-2 parts of a compatilizer, 2-4 parts of an anti-scratch auxiliary agent and 0.4-1 part of a lubricant. The high-strength modifiedPC material provided by the invention has good toughness, flame retardancy, wear resistance and scratch resistance, meets the application conditions of the PC material, and has greatly improved performance than a PC material.

Description

technical field [0001] The invention relates to the technical field of PC materials, in particular to a high-strength modified PC material. Background technique [0002] Polycarbonate (PC) has high impact strength and excellent mechanical, thermal and electrical properties, and is widely used in automobiles, aerospace, medical equipment, electronic appliances, electrical appliances, display casings, communication equipment casing components and other components. However, the current electrical shell products also have strict requirements on the surface of the material. One of the more difficult requirements is that the surface of the material must have a certain hardness and scratch resistance, that is, when the customer wipes the product, it cannot be easily scratched. At the same time, it is required that the shell of electronic and electrical communication equipment burns slowly or does not ignite in a fire hazard, so PC materials are required to have certain flame retard...
