High-temperature-resisting anticorrosive paint for power cable and preparation method thereof

Abstract

The invention discloses high-temperature-resisting anticorrosive paint for a power cable and a preparation method thereof and relates to the technical field of paint. The high-temperature-resisting anticorrosive paint is prepared from the following raw materials: 55 to 65 parts of bromine-carbon alkyd resin, 40 to 42 parts of modified ricinic acid polyester polyol, 34 to 36 parts of styrene-acrylic emulsion, 30 to 32 parts of compound filler, 29 to 31 parts of tobacco-fennel extract, 10 to 12 parts of a modified colloidal rheological thickener, 10 to 12 parts of a flame retardant, 8 to 10 parts of a light stabilizer, 8 to 10 parts of a de-foaming agent, 4 to 6 parts of a water repellent, 4 to 6 parts of an anti-freezing agent, 4 to 6 parts of a curing agent, 2 to 4 parts of a dispersant and 2 to 4 parts of a diluent. The high-temperature-resisting anticorrosive paint for the power cable, disclosed by the invention, can have a long-time anticorrosive and high-temperature-resisting protection effect, is not cracked when being used under various environments for a long time and has strong anti-ageing performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature-resistant anti-corrosion coating for power cables and a preparation method thereof. Background technique [0002] Existing cable fireproof coatings include solvent-based and water-based fireproof coatings. Solvent-based fireproof coatings have very good fire-retardant and flame-retardant effects, but because the solvent itself is flammable, and the toxic substances volatilize in a hot environment, and the degradation is poor , From the perspective of environmental protection, water-based cable fire retardant coatings are the future development direction. At present, the water-based cable fire retardant coating has basically achieved the goals of no pollution, non-toxic and tasteless, no threat to the health of construction workers, and a relatively strong heat insulation and fire prevention effect, and has good usability such as adhesion and flexibility. Due ...
