Abstract
The invention relates to silicon rubber used for an organic silicon self-adhesive tape and a synthesis process of the silicon rubber. The silicon rubber is prepared mainly by the following raw materials, by weight, 8-33% of methyl vinyl MQ silicon resin (M / Q=0.6-1.2), 14-40% of methyl vinyl silicon rubber, 11-34% of hydroxy silicon rubber and 20-55% of white carbon black. The synthesis process includes adding the raw materials in a kneading machine according to prescribed amount, uniformly stirring at normal temperature, and obtaining the silicon rubber used for the organic silicon self-adhesive tape. By reasonable raw material and proportion selection, the silicon rubber used for the organic silicon self-adhesive tape is synthetised. The obtained silicon rubber product has high resistance to high and low temperature (suitable for temperature environments of -45-200 DEG C), weather resistance, insulativity and excellent moisture-proof and waterproof performance through synergy of the raw materials, and comprehensive performance of the silicon rubber is better than that of existing silicon rubber of organic silicon self-adhesive tapes.
Description
technical field [0001] The invention relates to the technical field of silicone rubber self-adhesive tapes, in particular to a silicone rubber used for silicone self-adhesive tapes and a synthesis process thereof. Background technique [0002] Self-adhesive tape is a kind of dressing material, which is generally made into a tape with multiple isolation layers. When in use, tear off the isolation layer, fold and wrap it on the protected object under moderate stretching. After parking under certain conditions, it can be self-shrinking and fused into one, which has the functions of electrical insulation, heat insulation and waterproof sealing. It is widely used. Used in telecommunications, electronics, electromechanical, construction and other industrial fields. Silicone material is a semi-inorganic material because its molecular main chain structure is Si-O bond, the bond energy is higher than that of C-C bond, and the molecular main chain structure is saturated. Therefore, ...
