Silicon rubber self-adhesive tape

Abstract

The invention provides a silicon rubber self-adhesive tape which belongs to the technical field of chemical product manufacturing. The silicon rubber self-adhesive tape is made from methyl vinyl silicon rubber, fume silica, tackifier, vinyl silicon oil and iron red; the production technology comprises the steps of mixing the raw materials and placing the mixture in a gamma ray irradiation field of 60Co for radiation vulcanization. The product not only satisfies the manufacturing need of a special engine, but also can serve as an insulation protection product under high temperature and high pressure for electric insulation protection of a large-scale motor, an electromotor, special machines, and the like, and can satisfy the strong insulation sealing requirement on the industries such as shipbuilding, mining, petroleum production, chemical engineering, steel making and the like under severe environments of specially high temperature and high pressure.

Description

Technical field: [0001] The invention belongs to the technical field of chemical product manufacturing and discloses an electrical insulation sealing tape. technical background: [0002] Electrical insulation sealing tape is suitable for energy and power insulation sealing and insulation sealing of electrical appliance plugs. Due to market demand, cold-shrinkable products have the irreplaceable superiority of heat-shrinkable cable accessories, gradually replacing heat-shrinkable products and becoming the mainstream in the development of the power industry. It is difficult to control the degree of vulcanization through chemical vulcanization, and there are peroxide decomposition products, resulting in products The self-adhesiveness, tensile strength and elongation at break are uncontrollable and cannot meet the performance indicators required by the product. At present, the cold shrinkable power cable accessories in the domestic power industry have been controlled by foreign...
