[0002] In order to ensure the stable and reliable electrical performance and mechanical strength of motors and electrical components, it is necessary to insulate and seal between conductors, gaps and outlet leads. Electronic and electrical sealants are suitable for various structural bonding and sealing in industrial production, such as: Structural bonding of steel plates in car compartments, CRT picture tubes, circuit boards, car headlight gasket seals, etc. However, at present, the sealing rubber of electronic appliances will release small molecules during the curing process, which has a slight irritation to the skin and eyes

Abstract
The invention discloses a sealant for electrical apparatus insulation. The sealant for electrical apparatus insulation is prepared from, by weight, 50-60 parts of bisphenol A epoxy resin, 30-35 parts of water-soluble phenolic resin, 30-35 parts of natural rubber, 5-8 parts of methyl trichlorosilane, 3-8 parts of dimethyl dichlorosilane, 1-3 parts of dioctyl phthalate, 5-10 parts of rosin pentaerythritol ester, 3-6 parts of vinyl acetate, 5-9 parts of quartz powder, 4-8 parts of calcium carbonate, 2-5 parts of silica, 5-10 parts of manganese dioxide and 12-13 parts of carbon black. The sealant has excellent cold-hot alternating resistance performance, aging resistance performance and electrical insulation performance, can have the sealing and adhering effects on electronic components and parts and does not produce pollution to the surroundings.
Description
technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an electrical insulation sealant. Background technique [0002] In order to ensure the stable and reliable electrical performance and mechanical strength of motors and electrical components, it is necessary to insulate and seal between conductors, gaps and outlet leads. Electronic and electrical sealants are suitable for various structural bonding and sealing in industrial production, such as: Structural bonding of steel plates in automobile compartments, CRT picture tubes, circuit boards, automotive headlight gasket seals, etc. However, at present, the sealing rubber of electronic appliances will release small molecules during the curing process, which has a slight irritation to the skin and eyes. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an electrical insulating sealant, which has excellent res...
