Method for preparing hair cement foaming agent
The invention relates to an animal protein-based cement foaming agent. The animal protein-based cement foaming agent is prepared by the following steps: adding water, ox hair and the sodium hydrogen sulfite, pre-processing in a thermostatic water bath for 1-2h at the temperature of 80-95 DEG C, performing suction filtration, getting the solid, adding water and alkali, hydrolyzing for 5-7h at the temperature of 80-95 DEG C, performing suction filtration and centrifugation to obtain a hydrolysate; adding a proper amount of C to keep the pH neutral to obtain the animal protein-based cement foaming agent base solution; adding proper different varieties in the base solution, such as a foam stabilizing component and a strengthening component, and mixing uniformly to obtain the animal protein-based cement foaming agent. The obtained foaming agent is strong in foaming ability, fine and uniform in foam, high in stability, low in price and available in the raw materials, widens the tanning solid waste resource utilization approach and can well solve the solid waste recycling problem in the tanning industry if the foaming agent is widely popularized.
