Embodiment 1
[0014] A foam concrete foaming agent, the foaming agent comprises the following raw materials in parts by weight: 6 parts by weight of aminosiloxane, 25 parts by weight of isopropanol, 20 parts by weight of ethanolamine, 2 parts by weight of hydroxymethylpropyl cellulose, 3000 parts by weight of water.
[0015] The preparation method of above-mentioned foamed concrete blowing agent, concrete steps are as follows:
[0016] 1) Mix the weighed isopropanol and ethanolamine evenly, and heat up to 45°C;
[0017] 2) Dissolve the weighed aminosiloxane in the solution in 1), and stir slowly until uniform;
[0018] 3) Slowly add hydroxypropyl cellulose into the solution in step 2), stir evenly, raise the temperature and maintain it at 72°C, and react for 3.5 hours;
[0019] 4) The reacted solution is cooled to room temperature and discharged.
[0020] The effect test results are as follows: the foaming ratio is 80, and the bleeding volume is 6ml.
