Abstract

The invention provides a silicon rubber insulation self-adhesive tape for electrical equipment. The self-adhesive tape comprises raw materials in parts by weight as follows: 100 parts of vinyl methylsilicone rubber, 30-40 parts of reinforcing filler, 50-80 parts of thermal conductive filler, 3-5 parts of a structure controlling agent, 25-40 parts of a flame retardant, 15-30 parts of temperature-indicating pigment, 5-15 parts of a crosslinking agent and 10-15 parts of polymethyl borosiloxane. The self-adhesive tape has the function of changing own color with temperature variation and has excellent insulativity and flame retardance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a silicone rubber insulating self-adhesive tape applied to electrical equipment, and at the same time, the invention also relates to a preparation method of the self-adhesive tape. Background technique [0002] Silicone rubber self-adhesive tape has excellent weather resistance and electrical properties, and is convenient and quick to construct, environmentally friendly and non-toxic, and is widely used in power systems. In the past two years, with the expansion of the use of silicone rubber self-adhesive tapes in power systems, the industry has put forward new requirements for silicone rubber self-adhesive tapes. Some components of high-voltage equipment in the power system will cause local overheating during operation, which is difficult to be discovered by inspectors and maintenance personnel in time, and eventually cause operational failures, threatening the safety of people...
