Abstract

The invention discloses a high-toughness and aging-resistant ABS material, which comprises the following raw materials by weight: 100 parts of ABS resin, 0.5-5.0 parts of alkylated graphene oxide or alkylated reduced graphene oxide and 1.0-10.0 parts of a nano cellulose/attapulgite composite material. Compared with the prior art, according to the invention, graphene oxide is alkylated by tetraoctyl ammonium bromide and 1-iodododecane, so that the dispersity of graphene oxide in a polypropylene material can be remarkably improved, and the toughness of the ABS material is remarkably optimized; moreover, the nano cellulose/attapulgite composite material is also added, so that the toughness and aging resistance of the ABS material can be further improved.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a high-toughness anti-aging ABS material. Background technique [0002] ABS resin is a thermoplastic engineering plastic widely used after general plastics such as polypropylene, polyethylene, polystyrene, polyvinyl chloride, etc. Widely used, it has excellent properties such as easy processing, good impact resistance, corrosion resistance, high mechanical strength, good dimensional processing stability, and has the advantages of secondary processing. [0003] The physical and chemical properties of ABS resin materials are very excellent, but the bending strength and compressive strength of ABS materials are relatively poor, which is relatively weak among most plastic materials. The ABS resin material has stable properties and can exist stably in water, inorganic salts and various acids, but it can achieve a better dissolution state in solvents such as ketones, aldehydes and chlorinated ...
