Concrete foaming agent and preparation method thereof

Abstract

The invention provides a concrete foaming agent. The concrete foaming agent at least comprises, by weight, 5 to 30 parts of fatty alcohol polyoxyethylene ether sulfate, 5 to 15 parts of alkyl sulfate,4 to 8 parts of cocoamidopropyl betaine, 5 to 15 parts of an auxiliary agent, 10 to 30 parts of a foam stabilizer and 100 parts of water.

Description

technical field [0001] The invention relates to the field of concrete building materials, in particular to a concrete foaming agent and a preparation method thereof. Background technique [0002] Foamed concrete is also called foamed concrete. Its most notable feature is the formation of air bubbles in the concrete, which makes the concrete lightweight and thermally insulated. [0003] The foaming agent is made into foam by mechanical means, and then the prepared foam and concrete slurry are uniformly stirred to form a foam concrete mixture. "Stirring" makes the hard particles of these materials attached to the periphery of the foam, and the bubbles of the foam become individual bubbles separated from each other. The support body of the air cells is composed of the particles of the foam slurry and water. The pore shape of foam concrete is different from that of air-entrained concrete. It is not a single sphere, but it will deform to form a polyhedron under capillary actio...

Problems solved by technology

[0007] Generally, surfactants with excellent foaming properties are used as foaming agents. According to the ionic properties of surfactants, cationic foaming agents are expensive and have a certain impact on cement strength, so they are not used much; nonionic foaming agents The foaming ratio is generally small; although zwitterionic foaming agents can foam, they are not widely used due to their high cost
