Problems solved by technology

[0002] With the requirements of scientific and technological progress, the sealing strips commonly used in the power industry are not only required to have high insulation performance, but also require ozone resistance, heat aging resistance, low temperature resistance, and chemical corrosion resistance. In addition, this is also required. The product has environmental protection performance, and avoids skin allergies or other diseases caused by direct contact with the human body; therefore, traditional rubber products simply have good insulation properties, which are far from meeting the requirements of modern society

Abstract

The invention belongs to the field of rubbers, and concretely relates to an insulation sealing rubber strip for switch cabinets, and a production method thereof. The insulation sealing rubber strip comprises an inner layer and an outer layer; the inner layer is made from nitrocellulose resin, n-butyl methacrylate, cis-polybutadiene rubber, ethylene-propylene-diene monomer, bromobutyl rubber, reticular polyimide, calcium carbonate, paraffin oil, attapulgite, carbon nanofibers, stearic amide, zinc oxide, N-cyclohexyl-2-benzothiazole sulfenamide, sulfur, carbon black, white carbon black, tackifying resin, titanate, phenyl silicone oil, a plasticizer, an antioxidant and assistants; and the outer layer is made from polyimide, calcium carbonate, microcrystalline wax, the antioxidant and the assistants. The insulation sealing rubber strip has the advantages of good insulation property, good ozone resistance, good thermal ageing resistance, good low temperature resistance, good chemical corrosion resistance, good impact and water resistance, and high toughness, strength and wear resistance. The invention also provides the production method of the insulation sealing rubber strip.

Description

technical field [0001] The invention belongs to the field of rubber, and in particular relates to an insulating and sealing rubber strip for a switch cabinet and a preparation method thereof. Background technique [0002] With the requirements of scientific and technological progress, the sealing strips commonly used in the power industry are not only required to have high insulation performance, but also require ozone resistance, heat aging resistance, low temperature resistance, and chemical corrosion resistance. In addition, this is also required. The product is environmentally friendly and avoids skin allergies or other diseases caused by direct contact with the human body; therefore, traditional rubber products simply have good insulation properties, which are far from meeting the requirements of modern society. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an insulating sealing rubber...
