Foam concrete foaming agent and application thereof

Abstract

The invention discloses a foam concrete foaming agent and application thereof. The foam concrete foaming agent is prepared from anionic surfactant, a chemical foaming agent and a foam stabilizing agent, wherein the chemical foaming agent is aluminum powder, and the foam stabilizing agent is selected from one or two or three of hydroxyethyl cellulose, polyacrylamide and EVA emulsion. The anionic surfactant is prepared from sodium dodecyl benzene sulfonate, sodium dodecyl sulfate and a triterpenoidal saponin air entraining agent. The quality of a foam concrete product can be well ensured by using aluminum powder for forming for supplementing foam in an early stage through compounding. Cellulose, starch and other foam stabilizing agents are usually adopted as ingredients of a foam stabilizing agent in a foaming agent on the current market and are likely to form flocculent matter when mixed with a solution, and the foam stabilizing performance of the foam stabilizing agent is affected. By means of performance comparison, the mode of compounding cellulose ester and the EVA emulsion is adopted, so that the probability of generating the flocculent matter is reduced, and thus the stability of the foam stabilizing agent is improved.

Description

technical field [0001] The invention belongs to the technical field of building material manufacture, and in particular relates to a foam concrete foaming agent and its application. Background technique [0002] The development of foam concrete foaming agent in China is roughly divided into three stages. In the first stage, in the early 1950s, my country successfully applied rosin soap and rosin thermal polymer to the production and application of foam concrete; in the second stage, the upper In the 1980s, surfactant-based foaming agents were successfully developed and widely used in the production of foamed concrete; the third stage, at the end of the last century, my country entered the stage of R&D and application of protein active foaming agents. [0003] At present, the country is vigorously advocating the reform of building energy saving and wall energy saving. In recent years, foam concrete has attracted widespread attention from the whole society due to its environmen...
