Abstract

The invention discloses a protective adhesive for electrical appliances, which mainly comprises the following raw material components in parts by weight: 3.0-5.5 parts by weight of phthalic acid diester, 12-22 parts magnesium carbonate, 0.1-0.4 stearic acid, 4-4 parts magnesium hydroxide 15. Ethylene butylene 0.2-0.9, silicon dioxide 0.8-2.5, flame retardant 2.2-5.3, softening oil 2-7. The invention also discloses its preparation method, which includes the following steps: (1) weighing the raw materials according to the weight ratio, and then mixing them; (2) plasticizing the raw materials to obtain an intermediate product; (3) making the intermediate product Roller mixing; (4) After the roller mixing work is completed, the sheet is left to stand still; then the product is packaged and put into storage. The advantages of the present invention are: the present invention does not harden, flow and crack under the extreme environment of -40°C to +80°C; has no irritating smell, and does not pollute the environment.

Description

Technical field: [0001] The invention relates to electrical insulation protective glue, in particular to a stable performance and pollution-free electrical protective glue and a preparation method thereof. [0002] Background technique: [0003] In the electrical and telecommunications industries, electrical wiring is often required. When the wires are going to pass through buildings such as walls, after the installation is completed, the wire holes on the walls need to be sealed with electrical protective glue. At the same time, various electrical transmission lines have special requirements for the insulation, shock absorption and damping, flame retardancy and other characteristics of electrical protective glue. But the electrical sealant of prior art adopts polyvinyl chloride as raw material usually, and its cost is high, and the product of manufacture has pungent smell, can cause secondary environmental pollution; It is easy to change color after a long time, and the e...
