Modified soy protein foaming agent for concrete

Abstract

The invention discloses a modified soy protein foaming agent for concrete. The foaming agent consists of the following raw materials, by weight: 10-15 parts of a modified soy protein powder, 1-5 parts of hexadecyl trimethyl ammonium bromide, 1-5 parts of sodium dodecyl benzene sulfonate, 1-3 parts of rhamnolipid, 1-5 parts of Arabia gum, 1-5 parts of carrageenan, 0.1-1 part of hydrogen peroxide, 0.05-0.2 part of protease solution and 100-150 parts of water. The modified soy protein foaming agent for concrete provided by the invention can effectively improve the foaming capacity, foam stability, concrete compatibility, and various performances of the foam concrete, and provide technical support for preparation of novel wall material. The invention has advantages of simple product preparation process, low production cost, simple foaming process, high foaming rate of the foaming agent and good foam stability.

Description

technical field

[0001] The invention relates to a concrete foaming agent, in particular to a modified soybean protein concrete foaming agent. Background technique

[0002] With the improvement of the country's requirements for building energy-saving materials, foamed concrete has received more and more attention. Foamed concrete is made of cement, lime, fly ash, sand and admixtures and other main raw materials. A "tight cell" lightweight building material containing a large number of closed pores. Foaming agent is a key factor in the production of foamed concrete, and its performance directly determines the quality of foamed concrete. The concrete foaming agent requires that the foam produced should be small and uniform, with a long stable time, no large-scale cracking when it is added to the concrete, and uniform closed pores can be formed after the concrete is set, so that the foamed concrete that meets the national standard can be produced. products.
