Embodiment 1

[0025] (1) Add the following raw materials in the weight ratio to a 250ml three-necked bottle: 60g of water, 4 cow hairs (dried and shredded), 0.5g of sodium bisulfite, 0.2g of sodium dimercaptopropanesulfonate and 8-hydroxyquinoline 3.2-g, react in a constant temperature water bath at 80°C for 1 hour, and filter with suction to obtain solid A;

[0026] (2), add 35g of water to the solid matter A obtained in step (1), and mix evenly to obtain the protein cement foaming agent base liquid;

[0027] (3) Add 0.5 g of gum arabic powder, 0.3 g of sodium lauryl sulfate, 0.3 g of sodium lauryl alcohol ether sulfate and 1,8 - 0.6 g of dihydroxy-3-carboxyanthraquinone was mixed uniformly at room temperature for 60 minutes to obtain a hair cement foaming agent.

Embodiment 2

[0029] (1) Add the following raw materials in a 250ml three-necked bottle: 70g of water, 6g of cow hair (dried and shredded), 2.0g of sodium bisulfite, 0.7g of sodium dimercaptopropanesulfonate and 8-hydroxyquinoline 4.2g, react in a constant temperature water bath at 95°C for 2h, and filter with suction to obtain solid A;

[0030] (2) Add 50 g of sulfuric acid solution with a mass fraction of 40% to the solid A, and mix evenly to obtain the protein cement foaming agent base liquid;

[0031] (3) Add 2.0 g of triethanolamine, 1.0 g of sodium dodecylbenzenesulfonate, 1.0 g of sodium dodecyl polyoxyethyl ether sulfate and 1,8 - 2.1 g of dihydroxy-3-carboxyanthraquinone, mixed and stirred at room temperature for 60 minutes to obtain a hair cement foaming agent.

Embodiment 3

[0033] (1) Add the following raw materials in a 250ml three-necked bottle: 65g of water, 5g of cow hair, 1.25g of sodium bisulfite, 0.45g of sodium dimercaptopropanesulfonate and 3.7g of 8-hydroxyquinoline. React in a constant temperature water bath for 1.5h, and filter with suction to obtain solid A;

[0034] (2), add 42.5g of 20% sodium hydroxide to the solid matter A obtained in step (1), and mix evenly to obtain the protein cement foaming agent base liquid;

Abstract

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.

Description

technical field [0001] The invention relates to a protein-based cement foaming agent, in particular to an animal protein cement foaming agent and a preparation method thereof. Background technique [0002] Cement foaming agent is developed according to the characteristics and technical requirements of cement. In addition to its ability to generate large foam, it also needs to pay special attention to the stability and fineness of foam, as well as the adaptability of foam and cement and other cementitious materials. Since the incorporation of cement foaming agent can make the cement lightweight, heat preservation and heat insulation, and compensate the shrinkage and prestress of the tensioned steel bars, and fully fill the cement gap, it is suitable for non-load-bearing walls, roof insulation layers and other buildings. Industry, as well as thermal insulation of chemical heat pipes and other fields have a wide range of applications. [0003] The cement foaming agent has be...
