Embodiment 1

[0035] SDBS 25 grams; Sodium dodecyl sulfate 20 grams; triterpenoid saponins air-entraining agent 20 grams; aluminum powder 30 grams; Hydroxyethyl cellulose 2.5 grams; Polyacrylamide 0.5 grams; EVA emulsion 2.0 g.

[0036] Its application method is as follows:

[0037] Step 1. Calculate the consumption of each raw material according to the raw material ratio;

[0038] Step 2. Mix sodium dodecylbenzenesulfonate, sodium dodecyl sulfate, and triterpenoid saponins uniformly according to the formula ratio, and dissolve them in water with a mass ratio of 1:25 to 30 by stirring to form the initial foaming agent. solution;

[0039] Step 3, while stirring, uniformly disperse the foam stabilizer into the foaming agent solution, and stir at a high speed to form a foamed concrete foaming agent solution with a certain viscosity;

[0040] Step 4. Foam concrete foaming agent solution is foamed with a foaming machine, and the foaming...

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 manufacturing, in particular to a foaming concrete foaming agent. Background technique [0002] The development of foamed concrete foaming agents in China is roughly divided into three stages. In the first stage, in the early 1950s, my country successfully applied rosin soap and rosin thermopolymer to the production and application of foamed concrete; In the 1980s, surfactant-based foaming agents were successfully developed and widely used in the production of foamed concrete; in the third stage, at the end of the last century, my country entered the development and application stage of protein active foaming agents. [0003] At present, the state vigorously advocates the reform of building energy conservation and wall energy conservation. In recent years, foamed concrete has attracted wide attention from the whole society due to its environmental protection, energy saving, good thermal i...
