Abstract
The invention discloses an epoxy glass flake anticorrosive paint. The paint comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 25 to 38 parts of epoxy resin, 5 to 15 parts of polystyrene resin, 5 to 15 parts of butyral resin, 25 to 35 parts of glass flakes, 10 to 20 parts of solvent and 1.5 to 5 parts of plasticizer; and the component B comprises the following components in parts by weight: 50 to 70 parts of polyamide and 20 to 30 parts of solvent. The anticorrosive coating prepared by the anticorrosive paint has wide application range, excellent medium permeability resistance and abrasion resistance, tough coating, strong adhesion, high mechanical strength and long anticorrosive life. The coating with the dried film thickness over 100 microns can be obtained by utilizing the anticorrosive paint of the invention to carry out once coating, and the anticorrosive paint of the invention can be coated at normal temperature and solidified naturally at normal temperature, has simple and convenient construction, and does not require adding lining in construction, and has high mechanical strength.
Description
technical field [0001] The invention relates to an anti-corrosion coating, in particular to an epoxy glass flake anti-corrosion coating. Background technique [0002] Anti-corrosion coatings are widely used in the anti-corrosion of various underground and underwater steel pipelines. Anti-corrosion coatings are also used to improve the performance of concrete structures, as an anti-seepage, wear-resistant and anti-skid layer of concrete. [0003] In order to improve the service life of the equipment, the walls of various steel storage tanks and chemical containers are also coated with anti-corrosion coatings. [0004] Epoxy coal tar pitch glass flake coating contains coal tar pitch and is black. It is only suitable for anticorrosion of the inner and outer walls of crude oil, heavy oil, sewage, gas storage tanks and chemical containers. It is not suitable for light-colored petroleum products, benzene solvents and drinking water storage tanks. The inner wall is anti-corrosion...
