Abstract

Improved electric wire insulating varnish comprises raw materials in parts by weight as follows: 9-15 parts of aluminum hydroxide, 3-8 parts of modified phenolic resin, 10-15 parts of epoxy resin, 2-8 parts of polyvinyl formal resin, 4-9 parts of cresol, 4-6 parts of xylene, 5-8 parts of amino resin, 1-5 parts of polyvinyl alcohol, 2-7 parts of meta para cresol, 2-4 parts of mica, 3-5 parts of fire resistant fiber and 4-8 parts of propylene glycol. The improved electric wire insulating varnish has the benefits that the improved electric wire insulating varnish has good insulation capacity and has certain flame retardancy, and is widely applied to electric wires, cables and the like.

Description

technical field [0001] The present invention relates to an improved wire insulating varnish. Background technique [0002] An electrical insulating varnish material is a dielectric whose basic feature is to transmit the action and influence of electricity by induction rather than conduction. In foreign countries, the development of high-temperature-resistant insulating varnishes is relatively rapid. Since the early 1960s, with the development of the aerospace industry and the electronics industry in the United States, many brands of new high-temperature-resistant insulating varnishes have been developed. There are not many types of paints on the market, and their flame retardant and waterproof properties are not high, and their strength is not high. Therefore need a kind of high-performance insulating varnish. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an improv...
