Abstract

The invention discloses a heat-resisting antibacterial PA / ABS composite material which is prepared from the following components in parts by weight: 15 to 25 parts of ABS resin, 30 to 45 parts of PA resin, 5 to 12 parts of a compatilizer, 8 to 15 parts of a filler, 4 to 9 parts of a flexibilizer, 0.5 to 2 parts of an antibacterial agent, 0.3 to 0.9 part of an antioxidant, 0.4 to 0.8 part of a lubricant, 1 to 3 parts of a heat stabilizer and 2 to 5 parts of a flame retardant. The invention provides the heat-resisting antibacterial PA / ABS composite material. The composite material is relatively high in heat resistance and antibacterial performance, and can meet requirements of an existing engineering material for the heat resistance and the antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a heat-resistant and antibacterial PA / ABS composite material. Background technique [0002] PA resin has good comprehensive properties, including mechanical properties, wear resistance, chemical resistance and self-lubrication, and has low friction coefficient, certain flame retardancy, and easy processing. ABS resin has good dimensional stability, outstanding impact resistance, dielectric properties, abrasion resistance, good surface gloss, easy coating and coloring and other advantages. [0003] However, single PA resin and ABS resin have many deficiencies in mechanical properties, so many of them are PA / ABS composite materials. However, the existing PA / ABS composite materials have poor heat resistance, and at the same time, the antibacterial properties are not good. Well, it cannot meet the requirements of existing engineering materials. SUMMARY OF THE INVENTION ...
