[0003] Chinese patent document CN103709704A discloses a low-odor, low-emission PC / ABS alloy and its preparation method, including components: PC resin 30-80%; ABS resin: 4-66.4%; compatibilizer: 2-10%; Jellyfish granules 1-5%; additives 0.1-3%. This invention achieves the purpose of removing odor and reducing emission by adding jellyfish granules, but at high temperature, PC is prone to hydrolysis, and the impact performance will drop sharply
Chinese patent document CN103232700A discloses a low-odor PC / ABS reinforced alloy material and its preparation method. The PC / ABS alloy material comprises the following components and parts by weight: 30-70 parts of PC resin, 20-50 parts of ABS resin, 5-15 parts of diatomite, 0.1-1 part of antioxidant, and 0.1-1 part of lubricant. This invention reduces odor and emission performance by adding porous structure diatomite, but the activity of the inorganic substance itself is too low , the effect of reducing odor is very limited, and a large amount of addition is required

Abstract

The invention relates to the field of high polymer materials, and in particular relates to an ultralow-odor ultralow-emission PC / ABS alloy. The alloy is composed of the following components in parts by weight: 40-80 parts of PC, 20-50 parts of ABS, 2-10 parts of flexibilizers, 0.1-1 part of a lubricating agent, 0.1-1 part of an antioxidant, 0.1-2 parts of alcohols solvents and 0.1-2 parts of silicate porous materials. According to the alloy disclosed by the invention, the odor and high emission characteristics generated by small molecules can be removed, the odor and emission of the PC / ABS can be greatly improved, and the requirements on odor and VOC (volatile organic compounds) of interior decorating materials in various main engine plants are met.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with ultra-low odor and ultra-low emission and a preparation method thereof. Background technique [0002] Polycarbonate / styrene-butadiene-acrylonitrile (PC / ABS) has excellent mechanical properties, heat resistance, etc., and is a widely used engineering plastic. [0003] Chinese patent document CN103709704A discloses a low-odor, low-emission PC / ABS alloy and its preparation method, including components: PC resin 30-80%; ABS resin: 4-66.4%; compatibilizer: 2-10%; Jellyfish particles 1-5%; additives 0.1-3%. The invention achieves the purpose of removing odor and reducing emission by adding jellyfish particles. However, at high temperature, PC is prone to hydrolysis, and the impact performance will drop sharply. Chinese patent document CN103232700A discloses a low-odor PC / ABS reinforced alloy material and its preparation method. The PC / ABS alloy material comprises t...
