Abstract

The invention provides a high flowability, low viscosity and high impact resistance ABS resin and a preparation method. The high flowability, low viscosity and high impact resistance ABS resin comprises the following components in percent by weight: 55-90% of a monomer and rubber mixture and 10-45% of a diluent; and wherein the monomer and rubber mixture comprises the following components in partsby weight: 51-84 parts of styrene, 5-31 parts of acrylonitrile, 4-12 parts of rubber, 1-5 parts of a rubber viscosity dilution lubrication elastomer, 0.05-1 part of a molecular weight regulator and 0.01-1 part of an initiator. Compared with the existing high impact resistance ABS resin technology products, the high flowability, low viscosity and high impact resistance ABS resin prepared by the bulk method ensures the impact resistance performance, simultaneously reduces the viscosity of the ABS resin system, and has a relatively high melting index and relatively good flowability.

Description

technical field [0001] The invention relates to the technical field of synthesis and preparation of polymer materials, in particular to an ABS resin with high fluidity, low viscosity and high impact resistance and a preparation method. Background technique [0002] ABS resin is a terpolymer of styrene, butadiene and acrylonitrile. ABS resin has the advantages of the easy processability of styrene, the toughness of butadiene and the chemical corrosion resistance of acrylonitrile. With the development of society, ABS resin is widely used in household appliances, medical equipment, and automotive interiors. The ABS resin needed in China is increasing year by year. With the increasing demand for ABS resin, many functional ABS resins have been born, such as transparent ABS resin, high-impact ABS resin, heat-resistant ABS resin, and high-gloss ABS resin. , Matte ABS resin, etc. [0003] Nowadays, most of the special ABS resins needed in China still rely on imports, and major dom...
