Embodiment Construction

[0014] A modified 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 alpha-olefin sulfonate, poly 12 parts of acrylamine, 3 parts of malonic acid, and 60 parts of water; it is made by the following production steps:

[0015] 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;

[0016] 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;

[0017] 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;

[0018] 4) Add an acidic mixture of triethanolamine and methylcellulose to the foaming agent m...

Abstract

The invention discloses a modified concrete foaming agent. The modified concrete foaming agent is prepared from the following components: sodium dodecyl sulfate, triethanolamine, methyl cellulose, sodium alpha-olefinsulfonate, polyallylamine, propane diacid and water. The foaming agent provided by the invention has strong foaming capability and large foam yield per unit volume and allows produced foam to be maintained for a long time; 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 modified concrete foaming agent uses widely available raw materials, has low cost, is simple to prepare, produces fine foam which has good compatibility with a used medium 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 modified 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 purpose of the present invention is to provide a modified concrete foaming agent. [0004] The present invention is realized through the following technical solutions: [0005] A modified concrete foaming agent, made of the following ingredients in parts by weight, 15...
