Fluorocarbon paint for external walls of buildings

Abstract

The invention discloses fluorocarbon paint for external walls of buildings. The fluorocarbon paint is prepared from components in parts by weight as follows: 35-45 parts of a waterborne fluorocarbon resin emulsion, 1-2 parts of propylene glycol monomethyl ether acetate, 1-1.5 parts of diethylene diamine, 0.1-0.3 parts of a pH regulator, 0.5-1 part of a dispersant, 10-16 parts of titanium dioxide, 3-5 parts of butyl acetate, 0.5-1 part of isothiazolinone, 3-4 parts of a defoaming agent, 20-30 parts of purified water, 5-20 parts of a mixed solvent, 0-5 parts of matting powder, 0-1 part of a flatting agent, 2-8 parts of a high-temperature-resistant binder and 1-5 parts of an anti-freezing agent. A preparation method comprises the steps as follows: the waterborne fluorocarbon resin emulsion, titanium dioxide, the purified water, the dispersant, the mixed solvent and butyl acetate are sequentially added and mixed; the high-temperature-resistant binder, the flatting agent, propylene glycol monomethyl ether acetate and diethylene diamine are sequentially added; isothiazolinone, the antifreezing agent, the defoaming agent and the matting agent are added, the pH regulator is added, the mixture is stirred to be uniform and dried, and the fluorocarbon paint is obtained. The fluorocarbon paint has good performance and decoration effects and is corrosion-resistant, high in high-temperature resistance and anti-freezing.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fluorocarbon paint for building exterior walls. Background technique [0002] The oil-based paints currently used generally have good performance, but there are the following problems: [0003] 1) Solvent-based coatings contain a large amount of volatile organic compounds (VOC), which pollute the environment very seriously, and waste resources and energy at the same time; [0004] 2) The application requires high construction conditions and supporting materials, the coating is rigid, does not have good elasticity, and is easy to crack and peel; [0005] The water-based coatings currently used are convenient for construction, but there are the following problems: [0006] 1) The appearance of the coating film is poor, there are many dirty spots, large orange peel, etc.; [0007] 2) The performance of general decorative coatings is poor, and it is prone to discoloration in a ...
