Embodiment 1

[0013] The raw materials and dosage of the blowing agent are shown in Table 1. The preparation process is as follows: add 25 kg of sodium α-alkenyl sulfonate, 5 kg of alkyl glycoside, 0.01 kg of tea saponin, 0.05 kg of cocamidopropyl betaine and 0.25 kg of fatty acid methyl ester sulfonic acid into the reaction kettle in sequence, Keep the temperature at 40~60°C, control the pH value at 7~9, and mix well; then add 0.03kg of gum arabic, 0.005kg of gelatin, and mix evenly; then add 0.02kg of hydroxypropyl methylcellulose to the reaction kettle, poly Anionic cellulose PAC-HV 0.005kg, mix evenly; then add polyvinyl alcohol 0.05kg to the kettle, mix evenly; finally add sodium bentonite 0.0002kg, and make up the water to 100kg, mix evenly, to the required concentration, The obtained slurry can be used as a liquid high-efficiency compound foaming agent. Or the mixed slurry is spray-dried in a high tower to remove water to less than 5% to make a powdery high-efficiency compound foami...

Abstract

The invention discloses an environment-friendly compound concrete foaming agent and a preparation method thereof. The environment-friendly compound concrete foaming agent comprises the following components: sodium alpha-olefin sulfonate, alkyl glycoside, methyl ester sulfonate, cocamidopropyl betaine, tea saponin, arabic gum, hydroxypropyl methyl cellulose, gelatin, polyanionic cellulose, polyvinyl alcohol and sodium bentonite. The environment-friendly compound concrete foaming agent disclosed by the invention is alkalescent, achieves the pH value of 7-9, has the advantages of high foaming power, large foam expansion, fine uniform and tough foam, durability, stability, long foam stabilizing time, small bleeding amount, small deposition amount, good hard water resistance and suitability for water with various rigidities.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly compound concrete foaming agent and a preparation method thereof. Background technique [0002] Concrete foaming agent is an important component in the preparation of high-performance concrete materials. Concrete foaming agent can be used to prepare high-fluidity, high-durability concrete and cement insulation boards. The performance of the foaming agent is mainly reflected in its foaming ability and the stability of the foam over time. They affect the fluidity of the freshly mixed slurry and the volume stability of the cast body, and finally affect the bulk density and strength of the hardened body. The performance of the foaming agent It is a crucial factor affecting the performance and quality of foam concrete. As the construction industry has higher and higher requirements for concrete technology, it will inevitably lead to new ...
