Problems solved by technology

When the above base material meets the latex paint with water as the dispersion medium, it will rust, and the rust spots will be distributed on the entire paint film with the movement of the construction tools, eventually resulting in a large number of rust spots appearing on the paint film, greatly reducing its decorativeness

Abstract

The invention relates to a type of water-based antirust and antifouling paint used on a wall surface. The paint contains the following components in parts by weight: 20-60 parts of film forming substance, 1-10 parts of film-forming additive, 0.5-2 parts of copolymer of unsaturated monomer which contains fluoro aliphatic groups and unsaturated silane monomer, 0-5 parts of cosolvent, 0.1-1 part of corrosion inhibitor and appropriate amount of water. The invention further designs a preparation method of the paint. The water-based paint used for preventing rust and dirt on the wall surface is environment-friendly and economic; the water-based paint and common wall surface emulsion paints have the same the construction ways. The paint disclosed by the invention can prevent rust on the wall surface, has the capability of resisting stains and can reach better beautifying and decoration effects. The paint is an excellent paint which is used on the wall surface and is antirust, antifouling, environment-friendly and economic.

Description

technical field [0001] The invention relates to a water-based paint and a preparation method thereof, in particular to a water-based paint for preventing rust and stains on walls and a preparation method thereof. Background technique [0002] Paint is widely used in homes to coat interior and exterior surfaces. At present, there are many feedbacks on the market, especially in the humid southern areas, about the appearance of many rust spots after latex paint is applied on the wall. The base material of the wall can be roughly divided into two types. One is the putty layer. There are many kinds of putty powder used for leveling function, and the quality varies. The double ash powder and talc powder in the composition are all minerals, which must contain a large amount of metal impurities. , most of which are rust impurities; at the same time, the production equipment used by some small manufacturers is not well maintained; eventually resulting in a large amount of rust impur...
