Embodiment 1

[0031]

[0032] Soak the glass fiber in the mixture of coupling agent, silicone oil and copper powder for 2 hours, take it out, and dry it at room temperature for 24 hours. In the mixed solution, aminopropyltriethoxysilane accounts for 5%, silicone oil accounts for 20%, copper powder Accounted for 75%. This step is the first time the metal powder is attached to the surface of the fiberglass.

[0033] At the main feeding port of the twin-screw extruder, mix 6.1kg of PA6, 20g of antioxidant 1010, and 20g of antioxidant 168 evenly and then add them to the extruder, and pass the glass fiber with copper powder attached at a uniform speed through the aluminum treated with silicone oil. Powder (this step is the second time to attach the metal powder to the surface of the glass fiber. When the aluminum powder is treated with silicone oil, the ratio is 10% for the silicone oil and 90% for the aluminum powder.), feed it into the extruder from the side feeding port, By adjusting the ...

[0036]

[0037] Prepare copper powder mixture, 3% of aminopropyl triethoxysilane, 2% of isopropyl tri(dioctyl ichthyloxy) titanate, 5% of silicone oil, and 90% of copper powder. Soak the glass fiber in the mixture of coupling agent, silicone oil and copper powder for 2 hours, take it out, and dry it at room temperature for 24 hours. This step is the first time the metal powder is attached to the surface of the fiberglass. Then use silicone oil to treat the aluminum powder, the ratio is 5% for silicone oil and 95% for aluminum powder.

[0038] Mix 5.3kg of PA666, 20g of antioxidant 1010, and 20g of antioxidant 168 at the main feeding port of the twin-screw extruder, and then add them to the extruder, and pass the glass fiber with copper powder attached at a uniform speed through the silicone oil-treated aluminum powder (this step is the second time to attach the metal powder to the surface of the glass fiber), add it to the extruder from the side feeding port, adjust the sc...

[0041]

[0042] Soak the glass fiber in the mixture of coupling agent, silicone oil and copper powder for 2 hours, take it out, and dry it at room temperature for 24 hours. In the mixed solution, aminopropyltriethoxysilane accounts for 5%, silicone oil accounts for 10%, copper powder Accounted for 85%. This step is the first time the metal powder is attached to the surface of the fiberglass.

[0043] Mix 3.6kg of PA6, 50g of antioxidant 1010, and 50g of antioxidant 168 at the main feeding port of the twin-screw extruder, and then add them to the extruder, and pass the glass fiber with copper powder attached at a uniform speed through the aluminum treated with silicone oil. Powder (this step is the second time to attach the metal powder to the surface of the glass fiber. When the aluminum powder is treated with silicone oil, the ratio is 5% for the silicone oil and 95% for the aluminum powder.), feed it into the extruder from the side feeding port, By adjusting the extruder...

Abstract

The invention relates to an enhanced conductive nylon material and a preparation method thereof. The enhanced conductive nylon material comprises the following raw materials in percentage by weight: 40 to 70 percent of nylon, 10 to 40 percent of glass fibers, 10 to 40 percent of metal powder, 0.1 to 5 percent of coupling agent, 0.1 to 0.5 percent of antioxidant and 0.5 to 5 percent of silicone oil. The invention provides a method for thermoplastic conductive plastics by attaching the metal powder to the glass fibers twice and mixing the glass fibers, the metal powder and plastics for pelleting by utilizing the characteristics of easy machining and dispersion of the glass fibers in the plastics, and the prepared thermoplastic conductive plastics have the characteristics of simple and convenient production process, uniform dispersion of the metal powder, small addition amount, controlled conductivity and smooth surfaces of products.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic conductive plastics, in particular to a conductive nylon composite material added with metal powder and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, people's requirements for preventing electrostatic hazards and electromagnetic radiation are increasing. Due to the increasingly wide application of polymer materials such as plastics and rubber in various industries, in many applications, conductive or electromagnetic shielding requirements are also put forward for plastic products, such as electronic and electrical industries, semiconductor industries, mining machinery industries, especially And the defense industry. [0003] In order to solve these problems, people took the early stage of coating conductive paint or electroplating metal layer on the surface of plastic products. However, this method uses a large number of v...
