Abstract

The invention discloses a polyamide (PA) / acrylonitrile butadiene styrene (ABS) composite material. The PA / ABS composite material comprises the following components in parts by weight: 55-65 parts of PA, 40-50 parts of ABS, 5-8 parts of modified polystyrene (PS), 1-2 parts of initiators and 0.1-0.3 part of an antioxidant. The PA / ABS composite material is provided and used for solving the problem of poor compatibility of a blend of PA and ABS in the prior art.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to a PA / ABS composite material. Background technique [0002] Polyamide (PA), commonly known as nylon, is a thermoplastic engineering plastic widely used in automobiles, electronics, machinery and other fields. PA has excellent wear resistance, impact resistance and self-lubricating properties, and is resistant to a variety of chemicals, but it is not resistant to strong alkalis, and has high water absorption, low heat distortion temperature, and high creep. These shortcomings limit its application to a great extent. The blending modification of nylon with acrylonitrile-butadiene-styrene (ABS) improves the shortcomings of nylon and broadens the application field of nylon. The PA / ABS composite material prepared by blending not only has the wear resistance, impact resistance and self-lubricating properties of nylon, but also has the toughness and rigidity of ABS. However, nylon is a crystalline, ...
