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 ...

[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 to the complexity of the use environment, fireproof coatings are prone to aging, cracking and falling off when used in long-term high-temperature and corrosive environments, and it is difficult to meet the requirements of the cable use environment
