Problems solved by technology

[0002] With the gradual increase in the application of foam concrete (air bubble mixed light soil), the output and variety of foaming agents are also increasing, and the quality is also uneven. There are generally problems of poor stability and defoaming, resulting in Post-foamed concrete has low strength, many openings, and high water absorption, which seriously restrict the application and development of foamed concrete

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0022] In the technical solution of the present invention, the composite foam stabilizer suitable for surfactant foaming agents includes lauryl alcohol, ethylene glycol butyl ether, triethanolamine, hydroxyethyl cellulose, nano silicon, special stearic acid Salt, thickener and water.

[0023] The percentages of lauryl alcohol, butyl glycol ether, triethanolamine, hydroxyethyl cellulose, nano silicon, special stearate, thickener and water to the total mass of the composite foam stabilizer are: lauryl alcohol 0.5% to 3.5%, ethylene glycol butyl ether 2% to 8%, triethanolamine 1% to 12%, hydroxyethyl cellulose 0.5% to 1.8%, nano silicon 0.5% to 3%, special Stearate is 1% to 5%, thickener is 0.1% to 0.5%, and water is the remaining percentage.

[0024] Preferably, the percentages of lauryl alcohol, bu...

Abstract

The invention discloses a composite foam stabilizer and a preparation method thereof. The composite foam stabilizer comprises lauryl alcohol, ethylene glycol monobutyl ether, triethanolamine, nano silicon, hydroxyethyl cellulose, special stearate, thickening agent and water. By adopting the technical scheme, the invention can greatly prolong the stable time of the foam, reduce the bleeding quantity, and enhance the strength and waterproof quality of the finished product on the premise of not lowering the foaming coefficient of the original foaming agent.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite foam stabilizer and a preparation method thereof. Background technique [0002] With the gradual increase in the application of foam concrete (air bubble mixed light soil), the output and variety of foaming agents are also increasing, and the quality is also uneven. There are generally problems of poor stability and defoaming, resulting in Post-foamed concrete has low strength, many openings, and high water absorption, which seriously restrict the application and development of foamed concrete. Contents of the invention [0003] The purpose of the present invention is to propose a composite foam stabilizer and preparation method thereof, which is applicable to surfactant foaming agents, and can greatly increase the stability time of the foam without reducing the foaming multiple of the original foaming agent. Reduce the amount of bleeding, improve the st...
