Abstract

The invention discloses a high-gloss, flame-retarding and heat-resistance acrylonitrile-butadiene-styrene (ABS) alloy and a preparation method thereof. The invention provides a high-gloss, flame-retarding and heat-resistance ABS modified resin, which comprises an ABS resin, a PMMA resin, an AS resin, a compound flame-retarding master batch, a compatilizer, a heat resistant agent, an antioxygen and a brightener. The alloy retains the high physical properties of ABS resin and has high flame-retarding performance, high surface gloss and high thermal deformation temperature. The high-gloss, flame-retarding and heat-resistance ABS can be widely used in automobile, home appliance and electronic appliance industries and other industries.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-light flame-retardant and heat-resistant ABS alloy and a preparation method thereof. Background technique [0002] ABS (Acrylonitrile-Butadiene-Styrene) is composed of acrylonitrile-butadiene-styrene ternary copolymerization. Therefore, ABS has the corrosion resistance of acrylonitrile, the low-temperature impact resistance of butadiene, and the good processing performance of styrene, so it is widely used in the production of household appliances, mechanical parts, office supplies, electronic devices and other fields. [0003] Like most polymer materials, ABS is a flammable material (its limiting oxygen index is only 22), and it burns quickly when it is ignited. However, ABS applications often require flame retardancy and heat resistance requirements. In view of the shortcomings of ABS flammability and low heat distortion temperature, flame retardants and heat-r...
