Problems solved by technology

However, the production of the foaming agent in this patent requires heating and stirring at a temperature between 40°C and 100°C, which is troublesome to operate, and tea saponin and / or saponin are used as vegetable protein, which takes a long time to stabilize the foam and severely retards the setting, which affects the foamed concrete.

Abstract

The invention belongs to the technical field of foaming agents for concrete, and particularly relates to a composite vegetable protein foaming agent and a preparation method thereof. The composite vegetable protein foaming agent is prepared from the following raw materials in parts by weight, 10-20 parts of vegetable protein, 20-25 parts of a surfactant, 0.5-2 part of a foam stabilizer, 5-15 parts of an enhancer, 5-10 parts of a diluent and 45-70 parts of water, wherein the vegetable protein is prepared from tea saponin and cocoanut fatty acid diethanolamide in a weight ratio of 1:(1-3). The obtained composite vegetable protein foaming agent is small in bleeding rate and settling distance and completely meets the requirements of the foam concrete industry standard, and the prepared foam concrete is high in compressive strength.

Description

technical field [0001] The invention belongs to the technical field of foaming agents for concrete, and in particular relates to a compound vegetable protein foaming agent and a preparation method thereof. Background technique [0002] In today's foam concrete or foam lightweight soil industry, the requirements for foaming agents are getting higher and higher. Compared with rosin foaming agents and synthetic foaming agents, the development of protein foaming agents has encountered great difficulties. Proteins include plant proteins and animal proteins, and animal proteins are sourced from animal horny materials or animal fur, raw materials are polluted, and there are also a lot of pollution factors in the production process, so it is difficult to produce large quantities of foamed concrete in the cast-in-place market. However, although the plant protein foaming agent has also undergone a large number of experimental applications, it has a low foaming ratio and can only be us...
