Abstract

The invention provides a high-strength flame-retardant cable special material and a preparation method thereof, and relates to the technical field of cable special materials. The cable special material comprises the following raw materials in parts by weight: 100-120 parts of methyl vinyl silicone rubber, 1-5 parts of boron oxide, 15-20 parts of a reinforcing filler, 20-30 parts of low-melting-point glass powder, 15-20 parts of magnesium hydroxide, 5-10 parts of aluminum hydroxide, 1-5 parts of a modified flame retardant, 5-8 parts of a structure control agent, 3-5 parts of a vulcanizing agent and 15-20 parts of decabromodiphenyl ether. The prepared high-strength flame-retardant cable special material effectively reduces the ceramization temperature of a silicone rubber fireproof composite material, improves the ceramization conversion rate and the ceramization strength, has excellent flame retardancy and high resistivity, can meet the requirements of the industry, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of special materials for cables, in particular to a special material for high-strength flame-retardant cables and a preparation method thereof. Background technique [0002] A cable is an electrical energy or signal transmission device, usually a rope-like cable twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and often surrounds a Twisted in the center, the entire exterior is covered with a highly insulating cover. The cable has the characteristics of internal electrification and external insulation. [0003] The rapid development of my country's economy has led to the rapid development of the power industry, and a variety of electrical appliances have greatly increased the power consumption in life. This increases the probability of electrical fires, which will cause casualties and property losses. In today's society, the number of ele...
