Problems solved by technology

Although these materials meet the certain requirements of building materials and play a certain role in preventing mildew and moisture, the overall bonding strength of the glue is poor, the putty is easy to crack and fall off, and the water retention performance is poor. Too high viscosity makes it difficult to construct, and the process is complicated and the cost is high. In particular, it contains a large amount of harmful substances such as formaldehyde, which is not only harmful to the human body, but also environmental pollution cannot be underestimated.

Abstract

The invention discloses a water-soluble adhesive, which comprises the following parts: 30-65% pregelatinized starch, 10-20% 2488 polyvinyl alcohol, 13-37% cellulose and its derivant, 0-20% redispersion emulsion powder, 0. 15-0. 5% thickener and 0. 3-0. 8% high-activity zinc oxide, wherein each component is stirred evenly under the drying condition to form the product; the grain size of pregelatinized starch is 20-40 or 80-100 order, which can be allocated into gel powder to form common glue with 6% water after stirring 30min or interior-exterior wall putty powder adhesive after blending diflying powder or cement with weight at 0. 2: 10 directly.

Description

technical field [0001] The invention relates to a chemical adhesive, especially a water-soluble adhesive. Background technique [0002] With the development of the economy and the improvement of living standards, people pay more and more attention to the quality and grade of housing decoration. Chemical adhesives are used by industries, especially building materials and construction industries, especially decoration and decoration projects, because of their high bonding strength, good stability, sustainable raw materials used, and long pot life. For example, in terms of wall decoration, Shuangfei powder mixed with 107 or 801 glue; putty powder; cooked rubber powder with appropriate 107 glue and other construction adhesives are generally used. Although these materials meet the certain requirements of building materials and play a certain role in preventing mildew and moisture, the overall bonding strength of the glue is poor, the putty is easy to crack and fall off, and the ...
