Embodiment Construction

[0015] A concrete foaming agent, made of the following ingredients in parts by weight, 15 parts of sodium lauryl sulfate, 2 parts of triethanolamine, 2 parts of methyl cellulose, 8 parts of sodium α-olefin sulfonate, polypropylene amine 12 parts, 3 parts of malonic acid, 0.5 part of modified bentonite, 60 parts of water; it is made by the following production steps:

[0016] 1) Add water to the reaction kettle, heat it to 65-70°C and keep the temperature, add sodium lauryl sulfate, sodium α-olefin sulfonate, modified bentonite and polypropylene amine, heat up to 85-90°C, to Stir at 100-150r / min for 3 hours;

[0017] 2) Cool the raw materials in bag step 1) to room temperature, add malonic acid, and stir for 15-20 minutes to prepare the foaming agent mother liquor;

[0018] 3) Mix triethanolamine and methylcellulose in an acidic environment with a pH of 5-5.5, heat to 55-60°C, and keep for 20-30 minutes;

[0019] 4) Add an acidic mixture of triethanolamine and methylcellulose...

Abstract

The invention discloses a concrete foaming agent. The concrete foaming agent is prepared from the following components: sodium dodecyl sulfate, triethanolamine, methyl cellulose, sodium alpha-olefinsulfonate, polyallylamine, propane diacid, modified bentonite and water. According to the invention, through modification of bentonite, foam is allowed to be more uniform and finer, and foam concrete prepared from the concrete foaming agent has higher strength and better heat insulation performance; methyl cellulose and triethanolamine are doped, methyl cellulose can guarantee the foaming rate of the foaming agent, triethanolamine can greatly improve foam stability, and mixed modification of the foaming agent by methyl cellulose and triethanolamine enables the foaming agent to have ideal effect and stability of foaming of the mother liquor of the foaming agent to be improved; and the concrete foaming agent uses widely available raw materials, has low cost, is simple to prepare, and overcomes the problems of poor foamability and foam stabilization performance, high cost, complex preparation technology and the like in the prior art.

Description

technical field [0001] The invention relates to the field of chemicals, in particular to a concrete foaming agent. Background technique [0002] Foamed concrete has received more and more attention. Foamed concrete is made of cement, lime, fly ash, sand and admixtures and other main raw materials, which are poured and hardened after being poured and hardened. building materials. Foaming agent is a key factor in the production of foamed concrete, and its performance directly determines the quality of foamed concrete. At present, concrete foaming agents have problems such as poor foamability, poor foam stability, high cost, and complicated preparation process. Contents of the invention [0003] The object of the present invention is to provide a concrete foaming agent. [0004] The present invention is realized through the following technical solutions: [0005] A concrete foaming agent, made of the following ingredients in parts by weight, 15 parts of sodium lauryl sulf...
