Powdery compound flame retardant foaming agent for cement

Abstract

The invention discloses a powdery compound flame retardant foaming agent for cement. The foaming agent comprises the following raw materials in parts by weight: 0.5 to 0.8 part of sodium lauryl sulfate, 0.4 to 0.9 part of sodium alkyl benzene sulfonate, 0.2 to 0.7 part of sodium bicarbonate, 0.5 to 1 part of hydrogen peroxide, 0.3 to 0.7 part of calcium stearate, 0.4 to 0.9 part of hydrogen peroxide, 0.4 to 0.9 part of sodium pyrophosphate, 5 to 10 parts of hydrogen peroxide, 4 to 10 parts of quartz sand, 2 to 6 parts of a polycarboxylate high performance water reducer, 4 to 9 parts of attapulgite clay powder, 0.3 to 0.7 part of dibenzoyl peroxide, 0.8 to 1.5 parts of rosin, 0.5 to 1 part of sodium polyacrylate, 0.2 to 0.6 part of cocoyl diethanol amine, 5 to 10 parts of gelatin, 0.4 to 0.9 part of dimethyl pentane, 0.2 to 0.5 part of calcium chloride, 0.6 to 0.9 part of sodium carbonate, 3 to 5 parts of sodium hexametaphosphate, 0.4 to 0.7 part of sodium silicate, 0.4 to 0.7 part of lauryl dimethyl amine oxide, 0.3 to 0.7 part of lauryl dimethyl amine oxide, 0.3 to 0.8 part of cocoyl diethanol amine, 0.2 to 0.5 part of sodium hexametaphosphate, 1 to 5 parts of an air entraining agent, 0.3 to 0.6 part of diphenylphosphine, and 0.4 to 0.7 part of polyacrylamide. The foaming agent does not have corrosivity for cement and metal, and has the advantages that the foaming agent is high in storability, not easy to go bad and convenient to transport.

Description

Technical field [0001] The invention relates to the technical field related to construction, in particular to a composite flame-retardant foaming agent for powdered cement. Background technique [0002] With the increasing awareness of global safety and environmental protection, people have higher and higher requirements for fire safety and flame retardant products. Environmentally friendly flame retardants that are halogen-free, low-smoke, and low-toxic have become the goal pursued by people. [0003] Flame retardants are currently mainly organic and inorganic, halogen and non-halogen. Organic is some flame retardants represented by bromine series, phosphorus nitrogen series, nitrogen series and red phosphorus and compounds. Inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon series and other flame retardant systems. [0004] Foaming agents can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants. Foa...

Problems solved by technology

[0005] Although there are many types of flame retardants and foaming agents and they are widely used, they have the disadvantages of insufficient performance and cannot meet the needs of actual production and environmental protection. The existing flame retardants and foaming agents do not have the function of purifying air.
