Water-resistant putty is a kind of construction putty, especially a type of putty that can meet the N-type, that is, the water-resistant putty standard in the standard for building interior putty (JG/T3049-1998). "Building Interior Putty" (JG/T3049-1998) is a minimum standard that must be achieved in indoor building putty products. All putty that does not meet the requirements of this standard is a non-conforming product and is prohibited from being sold and used. In the "JG/T298-2010" standard for building interiors, in addition to the "water-resistant (N-type)" products, there are also "general (Y-type)" products. The most important difference between the two is the degree of solidity. . The water-resistant product requires a bond strength of 0.50Mpa or more in the standard state, and the general type is only 0.30Mpa or more. In addition, the water-resistant product requires the product to be immersed in water for 48 hours after being scraped, and no peeling, cracking, or drumming occurs. And can reach a bond strength of 0.30Mpa or more, and the general type product will fall off after being immersed in water, and the strength is zero. The intensity of water immersion after inspection in the standard is a more extreme destructive test. Of course, in real life, no one will immerse the wall of the putty putty in the water, but the problem pointed out by this experiment is very important. That is the service life of the product. Although the home will not be soaked in water, there will always be water vapor in the air. The wall is exposed to the air and is constantly eroded by water vapor. Good water resistance means long service life and poor water resistance means service life. very short. Generally speaking, after the water-resistant putty is properly applied to the wall, its service life should be more than 15 years, and the general-type putty can only reach about 5 years in the case of the outer layer with the protection of the latex paint.
