Problems solved by technology

Many years ago, real estate companies only built rough houses, or simply scraped dust in public areas, such as corridors and underground garages. In recent years, more real estate companies have considered the needs of owners and decorated public areas. Improve the quality of real estate and satisfy the owners. It can be said that there are endless decoration styles. Various styles such as tiling, plastering, putty, paint, latex paint, and marble coexist, but simple plastering and putty cannot achieve the desired effect. Even when walking in the corridor, it is easy to fall dust, affecting the owners, or pasting marble, ceramic tiles, etc. to improve the grade, thereby affecting the real estate price. Therefore, an economical and practical latex paint has become the best choice for real estate companies, decoration companies and property management companies. The best choice, not only can achieve a good decorative effect, the cost will not be significantly increased, and the practical life is longer, it has good scrubbing performance and anti-mildew performance
[0003] At present, when the relevant enterprises use or promote latex paint, they still use the roller coating method. Not only the construction cost is high, the efficiency is low, but also it is easy to cause serious roller marks on the surface of the paint film, the surface is rough, and it affects the appearance. When spraying, shrinkage cavities and pinholes are prone to occur. and other ills

Abstract

The invention provides airless spraying interior wall water-based paint special for engineering. The water-based paint comprises the following components in parts by mass: 8.5-11 parts of polymer emulsion, 3-6 parts of nano titania, 10-15 parts of kaolin, 20-40 parts of heavy calcium, 0.3-0.5 part of cellulose and 0.1-0.2 part of aluminum magnesium silicate, wherein the mass percentage of styrene in the polymer emulsion is 35-45%; the mass percentage of -OH is 4-10%; the lowest film-forming temperature is lower than 0 DEG C; the glass transition temperature is 30-50 DEG C. Compared with ordinary latex paint, the water-based paint disclosed by the invention is high in cost performance, excellent in overall performance and high in adaptability and can overcome orange peel shape, shrinkage cavity, needle holes and other film defects by virtue of airless spraying.
