Abstract

The invention relates to a fiber-reinforced extinction flame-retardant PC / ABS alloy and a preparation method thereof. The fiber-reinforced extinction flame-retardant PC / ABS alloy comprises the following components in parts by weight: 40-50 parts of PC resin, 20-30 parts of ABS resin, 10-15 parts of a DOPO-based nitrogen-phosphorus fire retardant, 5-10 parts of Kevlar chopped fibers, 15-30 parts ofcalcium silicate powder, 3-6 parts of silicon dioxide extinction powder, 3-8 parts of a toughening agent, 0.5-1 part of hyperbranched resin, and 0.2-1 part of an antioxidant. The fiber-reinforced extinction flame-retardant PC / ABS alloy is good in mechanical property without a fiber floating phenomenon, good in flame retardant effect, wherein a flame retardant level reaches a level V0, and low inglossiness, and has the apparent matte effect.

Description

technical field [0001] The invention relates to a fiber-reinforced matte flame-retardant PC / ABS alloy and a preparation method thereof, belonging to the technical field of plastic alloys. Background technique [0002] With the sustained and rapid development of my country's economy, the demand potential of my country's plastic alloy market is huge in recent years, especially the rapid growth of electronic communications, automobiles, and construction industries, which will drive the rapid development of my country's engineering plastic alloy industry. However, both research and production of plastic alloys in my country are still in a sporadic and scattered state, and have not yet formed a scale. The overall level of the industry is low, far from the advanced level of foreign countries. my country's plastic alloy research and development and processing technology level needs to be improved. [0003] The PC / ABS plastic alloy obtained by melting blending of PC and ABS can com...
