Problems solved by technology

Among them, incineration and landfill not only have poor economic benefits, but also cause serious environmental pollution.
Downgrading means that PC / ABS and PC waste double-color materials are not modified in any way, but are directly downgraded to ordinary plastics. Although this treatment method is better than incineration or landfill, it still fails to make full use of PC / ABS and PC materials. value, so the economic benefits are still low

Abstract

The invention relates to a recovery composition of thermoplastic matrix resin inferior materials. The recovery composition comprises, by mass, 75-90% of thermoplastic matrix resin inferior materials, 3-15% of a toughening agent, 1-9% of a phosphorus-based non-halogen flame retardant, and 0.3-0.5% of fluorine-contained resin. The invention further relates to an application of the recovery composition of the thermoplastic matrix resin inferior materials in manufacturing finished products.

Description

【Technical field】 [0001] The invention relates to a composition for recycling waste materials, in particular to a composition for recycling thermoplastic matrix resin waste materials and its application. 【Background technique】 [0002] PC / ABS alloy is a thermoplastic with good comprehensive performance, which combines PC (Polycarbonate, polycarbonate) and ABS (Acrylonitrile-Butadiene-Styrene, acrylonitrile-butadiene-styrene copolymer) The excellent characteristics of the material not only have the good formability of ABS materials, but also have the superior mechanical properties, impact strength, temperature resistance, and ultraviolet (UV) resistance of PC materials. Therefore, PC / ABS alloys can be widely used in the automotive industry and households. Electrical appliances, communication equipment and office equipment and other fields. [0003] With the widespread application of PC / ABS alloys in the 3C industry, a large amount of PC / ABS and PC scraps will be produced dur...
