Embodiment 1

[0011] Embodiment 1 provides a green and environmentally friendly heat-conducting nylon material, which is composed of the following components by weight: nylon: 44%; heat-conducting fiber: 5%; heat-conducting powder: 45%; lubricant: 4%; coupling agent: 0.8% ; Other additives: 1.2%.

[0012] First weigh nylon, coupling agent, and other additives according to the proportion and then mix them in the mixer at a low speed for 10 minutes. The heat conduction powder, heat conduction fiber and lubricant are also weighed according to the proportion and then mix them in the high mixer for 3 minutes. The mixing effect of auxiliary materials should be visually observed that the various particles and powders are basically uniform, without obvious agglomerates or agglomeration; the twin-screw extruder uses a 36 aspect ratio and medium-strength shear; heat-conducting powder, heat-conducting fiber, and lubricant are added in proportion from the side ;Using water-cooled strip cutting method, ...

Abstract

The invention relates to a manufacturing process of a heat conduction nylon material. The heat conduction nylon material is composed of the following components in percentage by weight: 5-70% of nylon, 3-45% of heat conduction fiber, 20-70% of heat conduction powder, 2-5% of lubricant, 0.2-1.0% of coupling agent and 0.3-5.5% of other assistants. According to the invention, the green environment-friendly heat conduction nylon material can be used instead of a metal raw material for the production of spare parts or shells, and simultaneously has higher physical and mechanical properties of the nylon as well as heat conduction and heat radiation functions and heat stability of the metal material; both the production and the procurement are convenient; and the relevant cost is greatly lowered. Thus, the competitive power is greatly improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a process for producing a heat-conducting nylon material, and also relates to a method for producing the heat-conducting nylon material. Background technique [0002] At present, the use of plastics to replace metals continues to expand internationally. Scientists from all over the world are actively looking for new functional thermoplastics through various experiments, which has become an important part of companies' efforts to win more customers and expand market share. [0003] However, the thermal conductivity of metal is not available in ordinary plastics. At present, in many fields such as civil electronic appliances / toys / communications / cables / military industry, parts that need to have certain heat conduction or heat dissipation functions are involved, and at the same time, they need to have high mechanical strength and certain temperature resistance....
