Problems solved by technology

[0002] In the prior art, foam concrete has a single function and can only be used as a slope filling layer or a thermal insulation slope layer, and its strength is low and its water absorption rate is high. Easy to crack, shell, sand, and not well combined with the structural layer or waterproof layer. In the prior art, a variety of foam agents are used, and a variety of preparation processes are implemented, such as Chinese patent application 200420023203, a foam concrete Its preparation method and special-purpose reaction tank, such as Chinese patent application 99236012 roof foam concrete waterproof insulation layer, as Chinese patent application 87103036A discloses a kind of foam concrete and preparation method thereof with grease plant as foaming agent, such as Chinese patent application 03126980X Disclosed is a method for preparing water-repellent foam concrete and its use, etc.
The above technical solutions have their own advantages and disadvantages, and there are certain limitations and defects. It is well known that the quality of foam concrete preparation is not only directly related to the foaming agent, but also has an important relationship with the construction material selection, construction technology, and construction equipment. Economically, the commercially available foam agents can be divided into animal type (Qinghai 3% type), plant synthetic type, rosin type and animal compound type. For example, the foamed concrete produced by the foam agent made of rosin cannot be used for pumps. However, the foamed concrete with low bulk density cannot be produced, and river sand should be added in the production, so it is easy to produce sand and crust, while the foamed concrete produced by plant type or other foaming agents has high water absorption and is easy to crack, so it can only be used alone As a filling or slope-finding product, the strength is also low
Some have a large expansion ratio but poor stability, some have good stability but low strength, and some cannot be pumped by mechanical means, etc.

Embodiment 1

[0035] The following content of the present embodiment has described the manufacture process of waterproof foam concrete:

[0036] First take 32 kg of powdered animal fur, hoof horn and other keratin protein powder, 1.8 kg of NaHSO 3 , 300 kg of water was added to the reactor, mixed and stirred, and pretreated at a constant temperature of 40°C for 2 hours. Then add 4.5 kg of Ca(OH) 2 , maintain a constant temperature of 80 ° C, hydrolysis reaction for 4 hours. After entering the filter and filtering, enter the reaction kettle for the second time, keep a constant temperature of 80°C, add an appropriate amount of sulfamic acid to neutralize to a pH of about 7. After reacting for 1 hour, enter the filter again, after filtering, enter the concentration tank for high-temperature dehydration, enter the reaction kettle for three times at a constant temperature of 60°C, add 1.0 kg of sodium dodecylbenzenesulfonate aqueous solution and 0.5 kg of sodium dodecylsulfonate aqueous soluti...
