Abstract

The invention discloses a shielding cable material. A preparation method comprises the following steps: (1) adding 10-15 parts by weight of glycerin tribenzoate to 50-80 parts by weight of acetone and stirring evenly; adding 5-8 parts by weight of trioctyl phosphate, stirring at 70-80 DEG C for 30-60min, adjusting the pH to 8-9 and reducing the temperature to 40-50 DEG C; adding 4-5 parts by weight of methyl benzoic acid and 2-4 parts by weight of isocyanate and adding a shielding copper-plated steel fiber, thereby greatly improving the shielding property of the cable material, wherein the plasticity of the cable material is affected through adding the shielding copper-plated steel fiber, the elongation at break of the cable material is effectively ensured and properly improved through adding a plasticizer to the cable material, and the mechanical strength and the fire resistance of a cable material layer are relatively greatly improved through adopting an ethylene-vinyl acetate copolymer, terpene resin and triallyl phthalate as main materials of the cable material layer and the combined action of the plasticizer and the copper-plated steel fiber.

Description

technical field [0001] The invention relates to a shielded cable material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. Shielding is to ensure the transmission performance of the system in an environment with electromagnetic interference. The anti-interference here should be the ability to resist external electromagnetic interference and the ability of the system itself to radiate electromagnetic interference. If the anti-shielding performance of the cable is not good enough, the external electromagnetic waves can easily cause interference to the cable, making the signal transmitted by the cable u...
