Red mud compound type foaming agent

Abstract

The invention discloses a red mud compound type foaming agent. The technical scheme is characterized in that the red mud compound type foaming agent comprises red mud powder, attapulgite clay powder having an air purification function, hydrogen peroxide, N,N-dimethyldodecylamine-N-oxide, coconut diethanolamide, modified polyethoxylated silicone, polyether modified silicone oil and water; paste ingredients of the red mud compound type foaming agent are firstly stirred into a paste, and then ingredients of the red mud compound type foaming agent are stirred and form a finished product of the red mud compound type foaming agent. The red mud compound type foaming agent has the characteristics of high foaming capability, high foam expansion rate, large foaming quantity per unit volume, uniform and fine foam cells, low possibility of breakage of foam cells, high demolding speed of a product, good surface smoothness and high long-term strength of the product. The product produced with the red mud compound type foaming agent has heat-preservation, thermal-insulation and soundproof effects and has an air purification function; and the red mud compound type foaming agent is suitable for producing light boards, light walls and noise reduction products.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a red mud composite foaming agent. Background technique [0002] Foaming agents can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants. Foaming agents with more uses include cement foaming agents, concrete foaming agents, plastic foaming agents, and polyurethane foaming agents. , rubber foaming agent, glass foaming agent, etc. [0003] Although there are many kinds of foaming agents and they are widely used, they have the disadvantages that their performance is not comprehensive enough to meet the needs of actual production and environmental protection, and the existing foaming agents do not have the function of purifying air. [0004] Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. The pH value of red m...

Problems solved by technology

A large amount of red mud cannot be fully and effectively utilized, and can only be stacked in a large area, occupying a large amount of land. The production of red mud has caused many direct and indirect impacts on human production and life, so the maximum It is imminent to reduce the output and harm of red mud and realize multi-channel and large-scale resource utilization
