Problems solved by technology

Its disadvantages are: not heat-resistant, not fire-resistant, not to mention fire-proof
[0004] The insulation degree of ordinary polyvinyl chloride materials is 0.6-110 and cannot be overloaded. Excessive load current can easily break through the flame-retardant insulating material and cause a short circuit; it is easy to be ignited in an open flame, releasing suffocating toxic gases and polluting the environment.

Abstract

The invention discloses a flame-retardant insulating material, comprising a PTT fiber base layer, an insulating layer and a thermal insulation layer. The insulating layer comprises the following raw materials by weight: 25 to 34 parts of organic silicone resin, 15 to 20 parts of an organosilicon cross-linking agent, 15 to 20 parts of silica, 11 to 16 parts of silicon hydroxide, 10 to 15 parts of magnesium hydroxide, 6 to 8 parts of iron oxide, 5 to 7 parts of barium sulfate, 5 to 6 parts of magnesium silicate, 3 to 4 parts of talcum powder, 3 to 4 parts of a lubricant, 4 to 5 parts of an anti-oxidant, 2 to 3 parts of a compatilizer and 1 to 2 parts of an organosilicon leveling agent, wherein the thermal insulation layer is a glass fiber layer. The flame-retardant insulating material has excellent performance and the characteristics of low smoke, no toxicity, no halogen and flame retardation; meanwhile, the flame-retardant insulating material has high tensile strength and shows excellent anti-electromagnetic interference performance when withstanding external mechanical force; and the flame-retardant insulating material is applicable to insulating layers of a variety of electric wires and cables.

Description

technical field [0001] The invention relates to a flame-retardant insulating material. Background technique [0002] Today, with the rapid development of high technology, more and more electrical equipment enters and exits people's homes. In order to make people's lives safer, flame-retardant insulating materials with better insulation effects are needed to insulate electrical equipment. [0003] In the existing work and life, the existing flame-retardant insulating materials are manufactured according to common DIN standards, such as: heat-resistant 90-degree coke-linked polyethylene, polyvinyl chloride. Its disadvantages are: not heat-resistant, not fire-resistant, not to mention fire-resistant. [0004] Ordinary polyvinyl chloride materials with an insulation degree of 0.6 to 110 cannot be overloaded. Excessive load current can easily break through the flame-retardant insulating material and cause a short circuit; in an open flame, it is easy to be ignited, releasing suf...
