Electromagnetic-interference-resistant fireproof insulating paint and preparation method thereof

Abstract

The invention discloses an electromagnetic-interference-resistant fireproof insulating paint. The electromagnetic-interference-resistant fireproof insulating paint is characterized by being prepared from the following materials in parts by weight: 28 to 34 parts of alkyd resin, 2 to 3 parts of cadmium carbonate, 22 to 26 parts of fluorocarbon resin, 5 to 7 parts of mineral oil, 1 to 3 parts of beeswax, 6 to 8 parts of polystyrene, 2 to 4 parts of titanium phosphide powder, 10 to 12 parts of 200# solvent oil, 6 to 9 parts of dimethyl benzene, 4 to 6 parts of lithopone, 2 to 3 parts of benzotriazole, 2 to 4 parts of a salt spray resistance assistant ZT-719, 1 to 2 parts of dicumyl peroxide, 1 to 3 parts of an antioxidant1010, 2 to 3 parts of dibutyl phthalate, 3 to 4 parts of flaky graphite powder, 4 to 6 parts of fused magnesite, 3 to 5 parts of N-methyl pyrrolidone, and 4 to 7 parts of an assistant. The paint provided by the invention has high strength and tenacity, good impact resistance, and also has abrasive resistance and oxidation resistance; the paint still keeps good fireproof and insulating performance in wet environment, and the added assistant has good electromagnetic interference resistance, and the paint can be applied to the protection of electrical equipment, reduces the danger coefficient, and improves the safety.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an anti-electromagnetic interference fire-resistant insulating varnish and a preparation method thereof. Background technique [0002] With the coverage of electrical appliances, electronics and power equipment in social life, although it brings many conveniences to people's life, it is indeed the harm of electromagnetic radiation to the human body and the environment. The easiest and most effective way to suppress electromagnetic radiation is to use electromagnetic shielding materials to achieve electromagnetic shielding. The electromagnetic shielding material realizes the reflection of electromagnetic waves through the impedance difference with the air and realizes the eddy current attenuation of electromagnetic waves through its own electromagnetic induction. Due to the good electrical conductivity of metal materials, traditional high-efficiency electromagnetic shi...

Problems solved by technology

However, due to the heavy weight of the steel plate itself, complicated production and installation, high cost, and difficulty in moving, the applicable fields of shielding materials are greatly limited. As a result, the current status of electromagnetic shielding is that, except in some very necessary occasions, such shielding materials have to be used. In
