Description

A kind of modified soy protein concrete foamer
Technical field
The present invention relates to a kind of concrete foamer, be specifically related to a kind of modified soy protein concrete foamer.
Background technology
Along with the raising of country to energy-saving building materials requirement, foamed concrete is subject to paying close attention to more and more widely, and foamed concrete is " close hole " light building material that contains a large amount of sealed porositys by the inside that after the main raw material fusion such as cement, lime, flyash, sand and admixture evenly, cast sclerosis forms.Whipping agent is a key factor of producing foamed concrete, and its performance is directly determining the quality of foamed concrete.Concrete foamer requires the foam producing to want tiny even, steady time is long, when joining concrete, do not produce on a large scale and break, after concrete coagulation, can form uniform sealed porosity, just produced thus the cellular concrete product that meets national standard.
In prior art, concrete foamer is from early stage changing to protein substance gradually as foaming source take surfactant-based material, the states such as the U.S., Japan, Italy develop multiple efficient protein matter class whipping agent in succession, and demonstrate gradually the advantage of its high stability, obtained larger application.Under the promotion of whipping agent, China has also developed the animal protein foaming agent of the multiple trade mark in succession abroad, and vegetable-protein whipping agent also starts occur and apply.China's whipping agent is not ideal enough on the whole, as on the low side in quality, function is on the low side, although some foam expansion is enough large, but poor stability, product strength are not high, and limited because of raw material sources, production cost is high, therefore exploitation is subject to very big restriction with application, cannot carry out large-scale promotion.
Summary of the invention
Object of the present invention is intended to overcome deficiency of the prior art, take aboundresources and the soybean easily producing as protein resource, obtain a large amount of, stable foaminess protein, provide one can effectively improve foaming power, foamed stability and concrete consistency, effectively improve the modified soy protein concrete foamer of the properties of foamed concrete.

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
Below in conjunction with embodiment, the present invention is further illustrated.
Embodiment
The preparation method of modified soy protein concrete foamer, comprises the following steps:
