Description

Coal ash compound type whipping agent
Technical field
The present invention relates to whipping agent, be specifically related to a kind of coal ash compound type whipping agent.
Background technology
Whipping agent can be divided into chemical foaming agent, pneumatogen and tensio-active agent three major types, and the many whipping agent of purposes has cement blowing agent, concrete foamer, plastics blowing agent, polyurethane foams, rubber pange agent, glass whipping agent etc.
Although whipping agent kind is many, application is also comparatively wide, there is performance comprehensive not, can not meet the drawback of actual production and environmental protection needs, the function that existing whipping agent does not also purify air.
Flyash receives to catch the thin ash got off from the flue gas after coal combustion, flyash is the primary solids refuse that coal-burning power plant discharges, flyash is one of industrial residue that the current discharge capacity of China is larger, and along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add process, will produce airborne dust, atmosphere pollution; River can be caused to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of coal ash compound type whipping agent is provided.
Coal ash compound type whipping agent is made up of flyash, the Attapulgite potter's clay powder with air purification function, hydrogen peroxide, dimethyl dodecyl amine oxide, cocounut oil acyl diethanolamine, silicone resin polyethers emulsion, polyether modified silicon oil and water.
The production method of coal ash compound type whipping agent: first stir in coal ash compound type whipping agent paste batching input low-speed mixer as paste, then the finished product that will stir in coal ash compound type whipping agent batching input homogenizer as coal ash compound type whipping agent.
Fly ash grain is multi-hole type cellular tissue, and specific surface area is comparatively large, and have higher adsorption activity, and Zhu Bi has vesicular structure, porosity, up to 50%-80%, has very strong water-absorbent.
The Attapulgite potter's clay powder with air purification function glues attapulgite clay by height, attapulite constant humidity amendment, natural-minerals adsorptive filter medium, Leafy twigs of Oriental Arborvitae, aluminium silicate fiber peacekeeping polyacrylamide form; there is good cohesiveness, plasticity-, thixotropy, resistivity against fire and thermostability; can the objectionable impurities such as formaldehyde, ammonia and benzene in effective absorbed air, protection of the environment and promote the healthy of people.
