Description
Technical field
The present invention relates to a kind of preparation method of albumen base cement blowing agent, more particularly to a kind of shavings cement blowing agent
Preparation method.
Background technology
Cement blowing agent be directed to cement characteristic and technical requirements research and development, it except possessing macrofoam generative capacity,
Also need to focus on stability, the exquisiteness of foam, and the adaptability of Binder Materials such as foam and cement etc..Due to cement hair
The incorporation of infusion can make cement lightization and insulation, heat-insulated, and compensate contraction and tension reinforcing steel bar produces prestressing force, and fully
Filling concrete gap, therefore in building trades such as non-bearing wall body, room face heat-insulation layers, and chemical industry heat distribution pipeline insulation
Suffer from being widely applied Deng field.
The main technical requirements of cement blowing agent stomata, be mainly reflected in it is following some：1）, stomata must be height closing
's.Only stomata closing can just make the foam beads after expansion be in good stable state；2）, pore size is of moderate size and
It is even.The intensity of cement blowing agent is inversely proportional with aperture, and when pore size is consistent, concentration will be avoided by force phenomenon, so as to carry
The intensity of cement blowing agent high；3）, stomata profile should to greatest extent close to spherical.The similarity of stomata subglobular is got over
Height, uniform force degree is bigger, and compressive property is better.
The material that not all classification can generate enough foams is used as cement blowing agent.It is removed with above-mentioned performance
Outward, also need to have no adverse effect the hydration process of cement.Cement blowing agent at present oneself through developing into forth generation, foaming agent also by
Gradually from single component to multi-component Complex Development.Cement blowing agent can be divided into surfactant-based foaming agent, synthesis class hair
Infusion, protein-based foaming agent, protein/surfactant compound foaming agent.Comprehensive foaming agent present Research, research work
Person mainly compounds to improve a certain single performance of foaming agent by inorganic salts, surfactant etc., thus cures the symptoms, not the disease, and
Surfactant production cost used is high.
As leather industry quickly develops, the total amount of solid leather wastes is also growing day by day.Discarded shavings water
Solution and then extraction collagen or other deep processings, can reduce the dirt that the solid waste produced in leather making process is caused to environment
Dye.Process hides solid waste important component of the comprehensive utilization as leather industry energy-conserving and environment-protective emerging strategic industries, be also
Solve the improper disposal of leather industry solid waste and the fundamental policy for storing up brought environmental pollution and potential safety hazard.It is same with this
Shi Tigao leather industry solid waste comprehensive utilization ratios, to implementing, refining, complete《Industrial repositioning upgrade programming（2011-2015
Year）》In the index of " percentage of industrial solid waste that is comprehensively utilized 72% " also function to certain effect.Also controlled to realize leather industry pollution
The benign cycle of reason, the basic target for realizing green process hides contributes.
The content of the invention
It is contemplated that putting forward a kind of preparation method of shavings cement blowing agent, hydrolyzed by by shavings, using its collagen egg
Group is compounded with foam stabilizing component and foaming component in white, and a kind of animal protein cement blowing agent is obtained.
The present invention uses following technical scheme：
