Water proof anticorrosive putty

Abstract

The invention discloses waterproof and rotproof putty, which consists of the following raw materials in weight percentage: 100 to 400 percent of gray calcium powder, 50 to 200 percent of ground calcium carbonate, 30 to 100 percent of light calcium carbonate, 100 to 400 percent of talcum powder, 50 to 150 percent of rubberlith, 30 to 100 percent of titanium pigment, 10 to 35 percent of polyvinyl alcohol. 2 to 6 percent of edible vegetable oil, 1 to 5 percent of engine oil, 2 to 8 percent of 95 percent industrial alcohol, 1 to 10 percent of a 10 percent acylamide solution and 280 to 480 percent of water. In the putty, the edible vegetable oil, the engine oil and the industrial alcohol are added to a polyvinyl alcohol solution to ensure that the a filler with higher content of the gray calcium powder can be evenly dispersed in a bonding material in order that the putty improves the waterproof and rotproof performances and keeps good construction property.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a putty for scraping and coating walls. Background technique [0002] Usually, the wall needs to be scraped and coated with putty before painting the paint. Putty is also called batch ash. It is mainly made of a mixture of adhesive materials and fillers. Not only can save paint, but also improve the smoothness of paint. The performance of putty, such as bonding strength, water resistance, etc., is an important factor affecting the durability of surface coatings. The traditional putty is composed of talcum powder and other fillers and bonding materials. It is mixed with a certain proportion of water and scraped on the wall during construction. This kind of putty has low bonding strength, poor water resistance and corrosion resistance. During use, it is easy to produce hollowing, falling off, cracking, moldy and other phenomena, and the wall surface coating also peels ...

Problems solved by technology

But because the ash calcium powder is added to the putty, it will thicken. If the content of ash calcium powder is too high, it will make it difficult for the filler to disperse evenly into the bonding material, and the putty will agglomerate, which will affect its construction and scraping. The amount of ash calcium powder in the putty is relatively low (generally not more than 5% of the total amount of putty), which limits the waterproof and anti-corrosion performance of this kind of putty
