Abstract

The invention discloses a modified ABS (Acrylonitrile Butadiene Styrene) foam material and a preparation method thereof. The preparation method specifically comprises the following steps: controllingthe temperature of an internal mixer to be 140-145 DEG C, mixing ABS resin granules, LDPE (Low-Density Polyethylene), a cross-linking agent, a foaming agent, zinc oxide, stearic acid and an antioxidant so as to prepare a pre-foamed blend material; and performing molding foaming on the pre-foamed blend material, thereby obtaining the modified ABS foam material. The modified ABS foam material prepared by the method disclosed by the invention is uniform in foam size and small in density, and the elasticity and overall performance of the ABS foam material are improved, so that the modified ABS foam material is well applied to the fields of packaging, automobiles, thermal insulation, buildings, buffering cushions, sound absorption lowering noise and the like.

Description

technical field [0001] The invention belongs to the technical field of foaming materials, in particular to a modified ABS foaming material and a preparation method thereof. Background technique [0002] ABS resin is a thermoplastic polymer material with high strength, good toughness and easy processing. Used in the preparation of various parts such as instruments, electrical appliances, machinery, etc. ABS resin is a graft copolymer of acrylonitrile (Acrylonitrile), 1,3-butadiene (Butadiene), styrene (Styrene) three monomers. Its molecular formula can be written as (C8H8)x·(C4H6)y·(C3H3N)z, but in fact it is often a mixture of butadiene-containing graft copolymer and acrylonitrile-styrene copolymer, among which acrylonitrile 15% to 35%, butadiene 5% to 30%, styrene 40% to 60%, the most common ratio is A:B:S=20:30:50, at this time the melting point of ABS resin is 175 ℃. The molding processing temperature of ABS resin is generally 210-230°C. ABS foam has excellent perfor...
