A waterproof foam stabilizer with adjustable setting time and preparation method thereof

Abstract

The invention discloses a waterproof foam stabilizer with adjustable setting time and a preparation method thereof. The weight ratio of each component in the waterproof foam stabilizer is: 40-60 parts of stearic acid, 8 parts of potassium hydroxide ~10 parts, 2~4 parts of soda ash, 25~38 parts of ammonia water, 0.06 parts of sodium fluoride, 6~9 parts of triethanolamine, 10~50 parts of sodium chloride, 5~15 parts of lithium carbonate, 814~904 parts of water. Applying the waterproof foam stabilizer prepared by the present invention to foamed cement can effectively control the setting rate of foamed cement under different production environment temperatures, and its mold collapse rate is far lower than that of the same type of common ammonium stearate emulsion stabilizer. Foaming agent, and can reduce demoulding and cutting time, shorten the construction period, suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of wall thermal insulation materials, and in particular relates to a waterproof foam stabilizer with adjustable setting time and a preparation method thereof. Background technique [0002] A large number of new houses are built every year in our country. In 2013 alone, there were 2.01 billion square meters of new houses, and the area of ​​new houses is still increasing every year. As the country develops a "resource-saving and environment-friendly" society, more and more attention has been paid to building energy conservation. The implementation of building energy conservation at the present stage is mainly to reduce the energy loss of cooling and heating in the process of building use. Realize building energy saving. Whether it is the energy-saving treatment of the newly built building envelope or the energy-saving renovation of the old building envelope, a large amount of thermal insulation wall material...

AI Technical Summary

Problems solved by technology

However, this is accompanied by a series of side effects: 1) The long-term strength of rapid-hardening cement is lower than that of ordinary Portland cement, resulting in a decrease in product strength; 2) The shrinkage rate of rapid-hardening cement is relatively large after hydration and coagulation, which is likely to cause a decrease in the compactness of the product and thus Causes cracking and increased water absorption; 3) When using part or all of rapid hardening cement instead of ordinary Portland cement, the price cost of production is increased, and the complexity of the production process is also increased
