The aqueous solution that described protein enzyme solution is mixed into by 0.2-0.3% neutral protease, 0.2-0.3% papoid and 0.05-0.1% stomach en-.
The preparation method of modified soy protein concrete foamer, comprises the following steps:
(1) by formulation ratio, modified soy protein powder, protein enzyme solution and water are mixed in reactor, at the temperature of 50-60 ℃ after hydrolysis reaction 6-8h, the modified soy protein whipping agent mother liquor making through the enzyme that goes out, centrifugal, filtration, filtrate being;
(2) in the above-mentioned modified soy protein whipping agent mother liquor making, add remaining raw material, heat to 40-50 ℃, stir, after raw material fully dissolves, be cooled to normal temperature and obtain modified soy protein concrete foamer.
Beneficial effect of the present invention
(1) in the present invention composition the material source of modified soy protein whipping agent mother liquor in resourceful soybean, easily a large amount of acquisition, and cheap, the feature of environmental protection good, easily realize large-scale industrialized production, obtains a large amount of, stable foaminess soy-protein;
(2) in the present invention, add hydrogen peroxide as gas reinforcing agent, can improve foaming probability, and hydrogen peroxide has certain germicidal action, make the effective service life effect of being improved of whipping agent, extend the work-ing life of whipping agent;
(3) modified soy protein concrete foamer of the present invention can effectively improve foaming power, foamed stability and concrete consistency, effectively improves the properties of foamed concrete, for the preparation of novel wall material provides technical support;
(4) product preparation process of the present invention is simple, and production cost is low, and foam process is simple, and whipping agent blistering rate is high, froth stability good.
Embodiment
