ABS composite material, application and preparation method thereof

Abstract

The invention relates to an ABS composite material, and application and a preparation method thereof, belonging to the technical field of macromolecules. The ABS composite material comprises the following raw material components in percentage by weight: 53.5%-89.6% of regenerated ABS, 0.1%-1% of a chain extender, 5%-15% of regenerated phenolic plastic, 2%-15% of silicon carbide, 2%-15% of aluminumoxide, 0.1%-0.3% of a coupling agent, 0.1%-0.5% of an antioxidant and 0-4% of other assistants. The ABS composite material provided by the invention has excellent mechanical properties and excellentshrinkage and warping resistance, and can be used for 3D printing.

Description

technical field

[0001] The invention belongs to the technical field of macromolecules, and relates to an ABS composite material, its application and a preparation method. Background technique

[0002] According to statistics, the world's plastic production reached 359 million tons in 2018, and China is already the world's largest plastic production country, accounting for 30% of the world's output. China's plastic consumption ranks first in the world, with 60.4215 million tons of plastic products produced in 2018. With the expansion of the use of plastics in the fields of electronic appliances, automobiles, plastic bags, etc., the accompanying waste products, plastic materials and plastic parts are increasing day by day. In order to deal with plastic waste at home and abroad, a large number of recycling companies have sprung up, and there are relatively mature processes and methods for recycling thermoplastics and thermosetting plastics. However, due to the irreversible cu...
