Problems solved by technology

However, its notched impact strength is low and its gloss is high, which seriously limits its application.
Especially when used as an automotive interior, its high gloss causes serious reflections, seriously affecting the driver's sight, and eventually leading to an increase in the incidence of driving accidents; in addition, spontaneous combustion of automobiles occurs from time to time, especially in In summer, excessively high temperature will cause spontaneous combustion accidents of automobiles, causing irreversible disasters. Therefore, requirements for flame retardant are put forward for the materials of automobile interiors.

Abstract

The invention relates to a low-gloss flame-retardant alloy consisting of the following components in percentage by weight: 33.7-64.4% of polycarbonate, 15-30% of polyethylene glycol terephthalate or acrylonitrile-butadiene-styrene resin, 10-15% of a flame retardant, 3-7% of a flame-retardant synergistic agent, 5-8% of a toughening compatilizer, 2-5% of a matting agent, 0.3-0.5% of an antioxidant and 0.3-0.8% of a processing aid. The low-gloss flame-retardant alloy provided by the invention is excellent in alloy phase comprehensive performance, low in cost and high in cost performance, reaches a flame retardant grade of UL94-V0, and can be widely applied to automotive interior parts.

Description

technical field [0001] The invention relates to an alloy material, in particular to a flame-retardant alloy with low gloss, and belongs to the technical field of material science. Background technique [0002] Flame-retardant alloy materials currently on the market have the advantages of good heat resistance, excellent electrical properties, and outstanding friction and wear resistance. However, its notched impact strength is low and its gloss is high, which seriously limits its application. Especially when used as an automotive interior, its high gloss causes serious reflections, seriously affecting the driver's sight, and eventually leading to an increase in the incidence of driving accidents; in addition, spontaneous combustion of automobiles occurs from time to time, especially in In summer, excessively high temperature will cause automobile spontaneous combustion accidents, causing irreversible disasters. Therefore, requirements for flame retardant materials for automo...
