Abstract

The invention provides a preparation method for elastic fluorocarbon paint. The preparation method for the elastic fluorocarbon paint includes the steps: (1) uniformly stirring fluorocarbon resin, partial solvents and dispersing agents in a stirrer; (2) adding the dispersing agents, pigments and fillers, and grinding to obtain grinding thick liquid; (3) placing the grinding thick liquid in the stirrer, sequentially adding elastic resin, defoaming agents and flatting agents, and uniformly stirring; (4) sequentially adding theological additives and residual solvents after the thick liquid is dispersed, and uniformly stirring to obtain main agents; (5) individually packaging curing agents to obtain packaged curing agents. According to the paint, anti-aging protection life of a coated substance can reach 25 years or more, and the paint has low VOCs (volatile organic compounds) and is better in toughness and elasticity and applicable to bridge concrete base surfaces, positions with easily cracked surfaces such as tunnels and piers and surfaces of other buildings with a certain water-proof and anticorrosion requirement.

Description

Technical field [0001] The present invention relates to an elastic fluorocarbon coating, in particular to a coating that has weather resistance for more than 25 years, excellent toughness and elasticity, and good protection for cracking concrete surfaces. Background technique [0002] Due to the internal stress of the concrete, small cracks usually appear on the surface of the concrete substrate of some bridge culverts and piers. If ordinary paint is applied, these cracks cannot be concealed and the building landscape is affected. [0003] The invention adopts the elastic fluorocarbon coating, so that the coating film has good stretchability, can maintain the integrity of the coating film when the substrate is cracked, and effectively saves the cost of surface treatment. Summary of the invention [0004] In view of this, the purpose of the present invention is to provide an elastic fluorocarbon coating with low VOC content, meeting the requirements for exemption of solvent-based co...
