Abstract

The invention belongs to the technical field of coatings and particularly relates to anticorrosion waterproof coating special for light steel and a preparation method thereof. The anticorrosion waterproof coating special for light steel is made from, by mass, 0.3-0.8 part of a dispersant, 0.1-0.5 part of a wetting agent, 1-2 parts of ethylene glycol, 0.1-0.5 part of a bactericide, 0.1-0.5 part ofa defoaming agent, 30-50 parts of TS waterproof emulsion, 5-10 parts of pure acrylic emulsion, 5-10 parts of silicone acrylic emulsion, 30-50 parts of ground calcium carbonate, 3-8 parts of kaolin, and 5-15 parts of titanium dioxide. The anticorrosion waterproof coating special for light steel has the advantages of zero toxicity, zero odor, zero pollution, high temperature resistance, low temperature resistance, aging resistance, acid and base resistance, good flexibility, low cost and the like. The preparation method provided herein is scientific and reasonable, is simple and provides convenience of construction.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and specifically relates to a special anticorrosive and waterproof coating for light steel and a preparation method. Background technique [0002] The light steel roof is easy to rust and leak. In the early traditional practice, the nail holes were wiped with structural glue and then sprayed with paint to remove rust. Normally, the product will age at most one year. In winter, due to the paint's high hardness and no toughness, thermal expansion and contraction are prone to cracks. Once people walk around, it will be broken when they step on it. Later, latex paint is used, which is neither waterproof nor durable, and no more than three years. , Began to rust and leak from the nail hole. [0003] The development time of light steel materials is only more than ten years, and the service life of light steel materials is about ten years, and rusting begins in 6-7 years of poor quality. In recent years, a...
