Abstract

The invention discloses an extinction nylon composite material. The composite material is prepared from the following raw materials in parts by weight: 75 to 80 parts of nylon 66, 7 to 9 parts of EPDM (Ethylene-Propylene-Diene Monomer), 0.7 to 0.9 part of rutile powder, 11 to 13 parts of functional master batch, 0.1 to 0.3 part of main antioxidant, 0.1 to 0.3 part of auxiliary antioxidant, 0.4 to 0.6 part of lubricant, 0.4 to 0.6 part of flowable agent and 0.5 to 0.7 part of nylon nucleating agent. The extinction performance of the nylon material prepared by the invention can meet the use requirements of almost all industries including special industries, has great significance, and provides assistance for the development of multifunctional composite performance materials.

Description

technical field [0001] The invention relates to the technical field of nylon materials, in particular to a matte nylon composite material and a preparation method thereof. Background technique [0002] Nylon 66 is one of the five major engineering plastics. It has excellent characteristics such as fatigue resistance, high rigidity, good heat resistance, low friction coefficient, good wear resistance, and stable chemical properties. However, it has high hygroscopicity, resulting in poor dimensional stability, and Low dry and low temperature impact strength. In order to improve the tensile strength, impact strength, modulus, wear resistance and dimensional stability of nylon 66, reinforcing agents such as glass fiber, nano-silica, carbon fiber and graphite are often added to the polymer matrix of nylon 66. Fiber, etc., to produce modified nylon 66. Modified nylon materials are widely used in automotive industry products, pump impellers and precision mechanical parts. [0003...
