Abstract

The invention is suitable for the technical field of high polymer materials and provides a nylon 66 composite material, a preparation method thereof and an electronic device. the nylon 66 composite material comprises the raw materials in percentage by weight as follows: 40%-65% of PA 66 resins, 8%-12% of a roughening agent, 20%-35% of heat conduction powder; 10%-15% of an antistatic agent, 2.5%-5.5% of a compatilizer, 0.1%-0.5% of a lubricating agent, 0.1%-1% of an antioxidant agent, 0.1%-2% of a coupling agent and 0.2%-0.5% of a nucleating agent, wherein the heat conduction powder is processed by the coupling agent. According to the invention, when the nylon 66 composite material is prepared, the coupling agent is used for processing the heat conduction powder, and two fillers of the heat conduction powder and a conductive agent are mutually matched and coordinated, so that the excellent heat conductivity and antistatic property can be obtained with low filler consumption, and simultaneously the prepared nylon 66 composite material has excellent physical and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nylon 66 composite material, a preparation method thereof and an electronic device. Background technique [0002] The output of nylon now ranks first in engineering plastics. Because of its excellent mechanical properties, good wear resistance, excellent oil resistance and solvent resistance, it also has the advantages of corrosion resistance, self-lubrication and good processing performance. Widely used in electrical industry, mechanical engineering, electrical engineering, automobile industry and aviation and other related fields. But nylon is an insulator, and its surface resistance is higher than 10 16 Ω, poor antistatic performance, easy to accumulate charges to generate static electricity during application, and the thermal conductivity of nylon is generally 0.25W / (m·K), which also limits its application in fields with heat dissipation and heat cond...
