Foam concrete foaming agent and preparation method thereof

Abstract

The invention relates to a foam concrete foaming agent and a preparation method thereof. The foaming agent is prepared from the following ingredients in parts by mass: 0.3 to 0.9 percent of anion active agents, 0.13 to 0.21 percent of methyl glucoside polyoxyethylene ether bi-olein, 0.01 to 0.04 percent of hydroxyethylcellulose and 0.02 to 0.05 percent of polypropylene crosslinking resin, wherein the anion active agents are one kind of materials from neopelex, sodium dodecyl sulfate or fatty acid polyoxyethylene ether sodium sulfate. According to the preparation method, the substances in the corresponding mass percentage are respectively taken, are mixed and are uniformly stirred to obtain the foam concrete foaming agent. The foam concrete foaming agent has the advantages that the raw materials can be easily obtained; the pollution is little; green and environment-friendly effects are achieved; the cost is low; the wide application can be realized; good economic benefits are realized; the parameters such as the foaming times, the settlement distance, the water bleeding quantity and the like of the foam concrete foaming agent are tested; relatively good effects are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a foam concrete foaming agent and a preparation method thereof. Background technique: [0002] The traditional foam concrete is to use the mechanical method to make the foaming agent aqueous solution into foam, then add gel material, water and admixture to make foam slurry, mix and stir, pour into shape or adopt the method of cast-in-place, and then Microporous lightweight material formed by natural curing. Due to the formation of a large number of closed air cells inside the concrete, the concrete has good physical properties such as light weight, high strength, heat insulation and heat preservation. Traditional foam concrete has a large volume density, usually 500-1200kg / m 3 , The thermal conductivity is large. With the advancement of foam concrete science and technology and production technology in recent years, and the continuous expansion of applicat...
