Problems solved by technology

Traditional silicone rubber insulators use DCBP as a vulcanizing agent. Because DCBP has toxic decomposition products, it takes a long time for secondary vulcanization to remove the decomposition products from the product.

Embodiment Construction

[0009] Silicone rubber insulators are widely used in high-voltage transmission lines and can be used in areas with different pollution levels. They have the characteristics of light weight, small size, unbreakable, high tensile strength and strong anti-pollution performance. Different types of silicone rubber insulators have different functions, and the structural height and creepage distance are also different. Silicone rubber insulators are mainly used in substations, with good hydrophobicity, aging resistance, tracking resistance and electrical corrosion resistance. . Through multiple tests, the present invention uses an addition vulcanization system as the vulcanizing agent before the refining (smelting temperature: room temperature-40°C), that is, before the refining, hydrogen-containing silicone oil, retarder, and platinum complex are added at one time as the vulcanizing agent. Additives, so that only one vulcanization treatment can meet the technical requirements, and c...

Abstract

The invention relates to high temperature resistant composite silicone rubber insulator formulation. The formulation comprises the following components in percentage by weight: 30-50 percent of methyl vinyl silicone rubber, 10-20 percent of fumed silica, 30-50 percent of aluminium hydroxide, 0.3-1.5 percent of hydroxyl silicone oil, micro-dosage of stearic acid , micro-dosage of platinum complex, 1-2 percent of hydrogen silicon oil, 0.02 percent of retarder, 1-3 percent of cerium siloxane, and micro-dosage of metaboric acid, wherein the content sump of the components is 100 percent. By adopting the formulation provided by the invention, only one-step vulcanization process is required, the heat resistance performance of the silicone rubber can be improved better, the components of the silicone rubber can be mixed uniformly, the processing performance of the rubber material can be improved, and the mechanical strength of the vulcanizing silicone rubber can be improved.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a high-temperature-resistant composite silicon rubber insulator formula. [0002] Background technique [0003] Different types of silicone rubber insulators have different functions, and the structural height and creepage distance are also different. Silicone rubber insulators are mainly used in substations, with good hydrophobicity, aging resistance, tracking resistance and electrical corrosion resistance. , has high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and brittle fracture resistance, light weight, easy installation and maintenance, and the installation dimensions of the upper and lower ends are the same as those of the corresponding porcelain post insulators The installation dimensions are the same and can be used interchangeably. Traditional silicone rubber insulators use DCBP as a vulcanizing...
