Abstract

The invention provides a foam foaming agent for cement and a preparation method of the foam foaming agent. The foaming agent is prepared from a foaming main material, a surface active agent, a foam stabilizer, a chelating agent, an organic solvent and water, wherein the foaming main material is lauryl sodium sulfate; the surface active agent is selected from one or more of alpha-sodium olefinsulfonate, laurinol polyoxyethylene ether sodium sulfate or lauramidopropylamine oxide; the foam stabilizer is silicon resin polyether. The foaming agent solves the problem that a traditional foaming agentis poor in performance and instable.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a foam foaming agent for cement and a preparation method thereof. Background technique [0002] At present, the country advocates a large number of building energy-saving and wall energy-saving reforms. In recent years, foam cement or foam concrete has been highly praised for its advantages of environmental protection, energy saving, and good thermal insulation performance. Traditional cement foaming agents include rosin and protein. [0003] The chemical structure of rosin-based foaming agents is relatively complex, and it is an anionic surfactant. It can react with calcium ions in cement to form insoluble salts. It needs to be heated and melted when used, and its foaming ratio is low and the foam stability is poor. Moreover, the production of rosin thermal polymer is based on toxic phenol as raw material, and its performance is roughly equal to that of rosin soap...
