Abstract

The invention relates to a foam concrete solid powdery foaming agent and a use method thereof. The foaming agent comprises the following ingredients in parts by weight: an anionic surfactant comprising 20-40 parts of lauryl sodium sulfate, 20-40 parts of alpha-olefin sulfonate, 5-15 parts of lauryl polyoxyethylene ether sodium sulphate and 3-10 parts of sodium lauroyl sarcosine, a nonionic surfactant comprising 1-5 parts of fatty acid alkanolamide, a chelting agent comprising 1-5 parts of triethanolamine; and foam stabilizer comprising 1-5 parts of one or more of polypropylene cross-linked resin, polyacrylamide and hydroxyethyl cellulose. The solid powdery foaming agent has the advantages of strong foaming capability, good foam stabilizing performance, long storage time and high cost performance, and is convenient for long-distance transportation.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a solid powder foaming agent for foamed concrete and a use method thereof. The foaming agent can be widely used in preparing foamed concrete, lightweight foamed cement boards and the like. Background technique [0002] Driven by the national building energy-saving and wall reform policies, foam concrete has been favored by the whole society in recent years due to its advantages such as waste utilization, environmental protection, energy saving, low price, good thermal insulation performance, and convenient large-scale and rapid construction. It has become more and more widely recognized and has been widely used in various fields. According to incomplete statistics, the annual output of foam concrete in my country was 5 million m3 in 2005. 3 , exceeded 6 million m in 2009 3 In 2012, the area of ​​building insulation layer poured with foam concrete exceeded 100 million m 2 , developed quite ra...
