Embodiment 1

[0012] Embodiment 1 provides an electromagnetic shielding nylon 66 raw material, which is composed of the following components by weight: nylon 66: 63%; metal fiber: 10%; carbon fiber: 10%; conductive graphite: 13%; heat stabilizer: 2% ; Coupling agent: 0.8%; Other additives: 1.2;

[0013] First, weigh nylon 66, heat stabilizer, coupling agent, and other additives according to the proportion and mix them in the mixer for 10 minutes at a low speed. 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; metal fiber / carbon fiber and conductive graphite are added in proportion from the side; The electromagnetic shielding nylon 66 material is obtained by sieving and dehydrating by adopting water-cooled strand cutting method.

Abstract

The invention relates to an organic polymer composite material, in particular to an electromagnetic shielding nylon 66 material and a preparation process thereof. The material comprises the following components in percentage by weight: 49.5-90 percent of nylon 66, 0-45 percent of metal fiber, 0-35 percent of carbon fiber, 0-30 percent of conductive graphite, 2-5 percent of heat stabilizer, 0.2-1.0 percent of coupling agent and 0.3-5.5 percent of other auxiliary agents. The electromagnetic shielding nylon 66 material can replace metal raw materials to produce parts or shells, and has higher physical and mechanical properties of the nylon 66 and the electromagnetic shielding function of the metal materials, thereby being convenient to produce and purchase, greatly reducing relevant cost and comprehensively improving the competitiveness.

Description

technical field [0001] The invention relates to an organic polymer composite material, in particular to an electromagnetic shielding nylon 66 material and a preparation method thereof. Background technique [0002] At present, the application of replacing natural mineral and metal raw materials with plastics continues to expand internationally. Scientists from all over the world are actively looking for new functional thermoplastics through various experiments, which has also become an important part of enterprises to win more customers and expand market share. [0003] However, the conductivity and electromagnetic shielding properties of metal materials are not available in ordinary plastics. At present, in many fields such as civil electronic appliances / toys / communications / cables / military industry, parts that require electromagnetic shielding functions, high mechanical strength, and certain temperature resistance are required. At present, the market of this series of prod...
