Problems solved by technology

[0004] Based on the above-mentioned methods, the polymerization modification process is complicated, and large-scale petrochemicals are often required for the production of special varieties during production, and a large amount of transition materials will inevitably be caused when switching between different products, resulting in great losses; Adding a modifier, the modified product has certain defects, and other properties will lose more after the amount of the modifier is too much, and the amount of the modifier is too small to meet the requirements of the flow performance

Abstract

The invention provides an acrylonitrile butadiene styrene (ABS) resin composition with good flowability. The composition comprises the following components in parts by weight: 20-30 parts of butadiene-styrene-acrylonitrile grafted copolymer with the resin content of above 60%, 10-30 parts of styrene-acrylonitrile copolymer with the acrylonitrile (AN) content of 22.5-24.5 and the number-average molecular weight of 7000-8000, 70-40 parts of styrene-acrylonitrile copolymer with the AN content of 23.5-25.5 and the number-average molecular weight of 4000-5000, 1.0-2.5 parts of N,N-ethylene bis stearamide, 0.1-0.4 part of magnesium stearate and 0.1-0.2 part of dialkypentaerythitoldiphosphite. Processing can be carried out at the temperature of 200-260 DEG C; the melt index of the resin composition is 40-70g / min; and the resin composition has the advantages of good mechanical property, simple production process and relatively low cost.

Description

Technical field: [0001] The invention relates to an ABS resin composition with excellent fluidity at 200°C-260°C and a melt index of 40-70g / min. Background technique: [0002] my country is the world's largest producer and consumer of household appliances. The consumption ratio of ABS resin in household appliances has remained high at about 60%. At the same time, the focus of the ABS resin market is gradually shifting to office equipment, automobiles, transportation and communication and building materials. and other fields. Nowadays, the increasingly detailed requirements for materials make ABS resins used in different application fields have different special properties. With the emergence and popularization of flat-panel TVs and the reduction in the cost of LCD screens, it will bring an explosion to the LCD TV industry. The production of components such as LCD TV backplanes requires the modification of ABS resin, which requires a large number of high-flow ABS resin produc...
