Abstract

The invention belongs to the technical field of coating materials and particularly relates to waterproof paint and a preparation method therefor. The waterproof paint provided by the invention contains the following ingredients in percentage by weight: 25% to 35% of polyurethane-acrylate resin, 10% to 20% of fluoro-resin emulsion, 5% to 10% of polyvinyl alcohol, 5% to 10% of titanium white, 1% to 3% of isocyanate, 1% to 3% of sodium polyacrylate, 1% to 3% of hydroxypropyl methylcellulose, 1% to 5% of anticorrosive and antibacterial agent, 1% to 3% of fireproofing agent, 1% to 5% of ethanol and 3% to 49% of water. The waterproof paint provided by the invention is environmentally friendly, safe, anticorrosive, antibacterial and flame-retardant and has relatively good waterproof performance and adhesive power. Meanwhile, the waterproof paint provided by the invention is short in drying time and has relatively good extensibility and heat resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof coating and a preparation method thereof. Background technique [0002] At present, waterproof coatings are mainly divided into oil-based waterproof coatings and water-based waterproof coatings. Because oil-based waterproof coatings contain organic solvents, long-term use of oil-based waterproof coatings is toxic to the human body and the environment. Moreover, oil-based waterproof coatings will be fattened when they are in contact with water for a long time. , cracking and other phenomena. Although water-based waterproof coatings do not contain organic solvents, water-based waterproof coatings usually have poor adhesion and are easy to fall off from the substrate. At the same time, water-soluble paints are susceptible to biological damage. Since the production of bacteria depends on the environment with water, most of the existing water-soluble paints ...
