Thermal-conductive flame-retardant weatherproof anti-static environment-friendly insulating material for cables and preparation method of insulating material

Abstract

The invention discloses a thermal-conductive flame-retardant weatherproof anti-static environment-friendly insulating material for cables. The insulating material comprises, by weight, 50-60 parts of chlorinated polyethylene rubber, 7-11 parts of coupling agent, 2-4 parts of antistatic agent, 5-8 parts of antimony trioxide, 3-8 parts of calcium stearate, 5-10 parts of toughening agent, 1-2 parts of antioxidant, 2-6 parts of ultraviolet light absorber, 6-8 parts of flame retardant and 8-14 parts of insulating nanometer thermal conductive filler. The insulating material has good anti-oxygen effect, high stability and outstanding thermal conductivity, has high tensile strength and elongation at break, and also has good flame-retardant properties, anti-static performance and insulation performance, thereby being suitable for serving as the outer wrapping insulation material for cables; the preparation method of the insulating material has the advantages of low material cost, easy availability in raw materials, simple process, high practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a heat-conducting, flame-retardant, weather-resistant, anti-static, and environment-friendly insulating material for cables and a preparation method thereof. Background technique [0002] Today's 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. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. The continuous and rapid growth of China's economy has provided a huge market space for cable products. The strong temptation of the Chinese market has made the world focus on th...

Problems solved by technology

However, there are still defects in the cable materials currently on the market, some are too viscous, and some have low elongation, so we urgently need to improve the material, and in the prior art, in order to increase the flame retardant characteristics of the cable, a large amount of inorganic retardant has been added. Combustible materials, resulting in an increase in the overall hardness of the cable, and even prone to outer layer breakage
