[0004] But on the whole, the above-mentioned patents should have imperfections. Although some anti-cracking effects have been improved, with the development of science and technology and the improvement of people's requirements, they still cannot meet people's needs; although some have better anti-cracking effects , but loses other properties of the coating
Therefore, these patented technologies still need to be further improved

Abstract
The invention discloses anti-cracking exterior wall putty. The anti-cracking exterior wall putty comprises the following components in percentage by weight: 15-17% of pure acrylic elastic emulsion, 10-12% of silicone-acrylate elastic emulsion, 0.5-1% of carboxymethyl cellulose, 2-3% of polyacrylonitrile fiber with the length of 2-6mm, 0.4-0.6% defoaming agent, 0.5-1% of preservative, 0.8-1.2% of thickening agent, 14-16% of white cement, 4-6% of cassava gelatinized starch, 10-12% of heavy calcium carbonate, 5-7% of talcum powder and the balance of water. After being subjected to heat and cold circulation for many years in cold regions, the anti-cracking exterior wall putty disclosed by the invention does crack; tests at minus 40 DEG C to 40 DEG C show that the anti-cracking exterior wall putty has a very good anti-cracking effect; after the anti-cracking exterior wall putty is scraped, other overcoat agents do not need to be sprayed; the anti-cracking exterior wall putty is not weathered, does not peel and has high bonding strength.
Description
Technical field [0001] The invention relates to the technical field of building materials, in particular to a crack-resistant external wall putty. Background technique [0002] With the rapid development of my country’s construction industry, putty has become one of the main decorative materials in the interior and exterior wall decoration. It has become more and more popular in the market for its good decoration, durability, ease of construction and good cost performance. welcome. However, with the increase in the amount of work, some common engineering quality problems have appeared. The most serious one is that after a period of time after the painting is completed, such as one year later, the wall will appear to be cracked, which not only brings damage to the building The damage caused by the damage caused by water seepage, and the paint loses its decorativeness, which seriously affects the function and beauty of the building. [0003] The common putty currently sold on the ma...
