PA66 plastic cement composite material

Abstract

A disclosed PA66 plastic cement composite material is characterized by comprising the following substances in parts by weight: 31-40 parts of PA66 resin, 11-16 parts of PVC resin, 5-9 parts of acrylic resin, 3-8 parts of aluminium silicate, 1-4 parts of a carbide, 9-13 parts of polyisoprene rubber, 5-7 parts of an isocyanate, 11-16 parts of polytetrafluoroethylene gum, 3-5 parts of zirconium oxide, 4-8 parts of silicon dioxide, 3-7 parts of trimethoxy(methyl)silane, 11-14 parts of poly(4-methyl-1-pentene), 3-8 parts of butadiene, and 2-8 parts of styrene. The plastic cement modified material possesses good flame retardation property, strong safety, excellent mechanical performances, good tensile strength, bending strength, impact strength, heat deformation temperature resistance and other performances, and an electronic connector prepared from the plastic cement modified material is strong in flame retardation property and long in service life.

Description

technical field [0001] The invention relates to a PA66 plastic composite material. Background technique [0002] PA66 plastic has strong impact resistance and high strength. In recent years, with the rapid development of electronics and consumer electronics, there are more and more applications for electronic product connectors. Electronic product connectors are mainly composed of plastic and contact copper sheets. , and PA66 plastic is the main raw material used to produce connector plastics for electronic products, so the application of PA66 plastics continues to increase, but PA66 plastics themselves are flammable and combustible materials, and their application in the electronic field has greater safety hazards, so It is very necessary to develop flame-retardant PA66 plastics with flame-retardant effect, low toxicity, and little environmental pollution. [0003] The existing flame retardant modification of PA66 plastics is mainly achieved by adding halogenated flame ret...
