Abstract

The invention discloses a super-tough nylon 66 composite material. The super-tough nylon 66 composite material comprises the following raw materials by mass: 70 to 80 parts of a nylon 66 resin, 18 to 30 parts of a flexibilizer, 0.3 to 2 parts of a chain extender, 0.1 to 0.2 part of a hindered phenol anti-oxidant, 0.1 to 0.2 part of a phosphite anti-oxidant and 0.1 to 0.4 part of a lubricant. A preparation method for the super-tough nylon 66 composite material comprises the following steps: 1) uniformly mixing all the raw materials; and 2) carrying out extrusion granulation and drying. The composite material prepared in the invention has high tensile strength, bending strength and notch impact strength and high glossiness.

Description

technical field [0001] The invention relates to a super-tough nylon 66 composite material and a preparation method thereof. Background technique [0002] Nylon 66 has become a widely used engineering plastic due to its high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and molding, etc., but it has poor impact strength in dry state and low temperature. In order to adapt to different application requirements, it is necessary to toughen and modify nylon 66. The existing toughening modification methods mainly include the following three types: one is to use polyethylene (PE), polypropylene (PP) and other polyolefins Supplemented with their maleic anhydride (MAH) grafts for modification; the second is polyolefins such as ethylene-octene copolymer (POE), ethylene-propylene-diene rubber (EPDM), and ethylene-propylene-diene rubber (EPR) Elastomers are modified with their maleic anhydride (MAH) grafts; the third is dire...
