Abstract

The invention discloses a fireproof paint for electrical equipment. The fireproof paint is prepared from the following raw materials in parts by weight: 20-30 parts of phenyl vinyl silicon resin, 25-40 parts of vinyl chloride-acrylate latex, 8-15 parts of bisphenol A type epoxy resin, 10-15 parts of pentaerythritol, 15-25 parts of ammonium polyphosphate, 15-26 parts of melamine, 10-15 parts of mullite, 5-10 parts of vermiculite, 1-5 parts of polyimide fiber, 0.4-1 part of a thickener, 2-5 parts of a film-forming agent and 30-40 parts of water. The fireproof paint is strong in cohesive force, high in mechanical property, high in crack resistance, water resistance and acid and alkali resistance, and high in fireproof performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a fireproof coating for electric equipment and a preparation method thereof. Background technique [0002] The working environment of power equipment is often in a high-temperature environment, which is prone to fire. In recent years, people often coat fire-resistant coatings on the surface of power equipment. Fire-resistant coatings usually play the role of decoration, anti-rust, anti-corrosion and prolong the use of protected power equipment. The role of life, when encountering a fire situation, the fire retardant coating can quickly undergo physical and chemical changes, play a role in heat insulation, prevent the spread of flames, and prevent the occurrence and development of fire. Therefore, coating fire retardant coatings on the surface of electrical equipment has Significance. [0003] The Chinese patent application with the publication number CN1056...
