Abstract

The invention relates to a silicone rubber composition and a process for using it to produce a silicone self-adhesive tape. The silicone rubber composition is mainly made of the following raw materials in terms of mass percentage: 8-33% of methyl vinyl MQ silicone resin; 14-40% of methyl vinyl silicone rubber; 11-34% of hydroxyl silicone rubber; Carbon black 20-55%. The silicone rubber composition is used as an adhesive, glued on the non-alkali glass fiber cloth by scraping, and after being cured in an oven, it is wound up to obtain a finished silicone self-adhesive tape. Through the synergistic effect between the raw materials described in the present invention, the obtained silicone rubber product has good high and low temperature resistance (suitable for -45-200°C temperature environment), weather resistance, insulation and excellent moisture-proof and waterproof performance. The comprehensive performance is better than the silicone rubber of the existing silicone self-adhesive tape. The silicone rubber is coated on the non-alkali glass fiber cloth. Compared with other resins, it has better adhesiveness and softness, and is not easy to fall off during use.

Description

technical field [0001] The invention relates to the technical field of silicone rubber self-adhesive tapes, in particular to a silicone rubber composition and a process for using the same to produce silicone self-adhesive tapes. Background technique [0002] Self-adhesive tape is a kind of dressing material, which is generally made into a tape of a composite isolation layer. 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 saturate...
