Description
Technical field
The present invention relates to whipping agent, be specifically related to a kind of coal gangue compound foaming agent.
Background technology
Whipping agent can be divided into chemical foaming agent, pneumatogen and tensio-active agent three major types, and the many whipping agents of purposes have cement blowing agent, concrete foamer, plastics blowing agent, polyurethane foams, rubber pange agent, glass whipping agent etc.
Although whipping agent kind is many, apply also extensivelyr, exist 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.
Coal gangue is the solid waste discharging in coal mining process and coal washing process, is a kind of black gray expandable rock lower, harder than coal with a kind of carbon content of coal seam association in coalification course; Comprise the spoil of washing of choosing in the spoil of extraction from top board, base plate and interlayer in digging gangue in tunnelling process, mining process and coal washing process.
China accumulates coal gangue and reaches more than 1,000,000,000 tons, also will discharge every year 100000000 tons of coal gangues, not only piles up and takes up an area, and can also spontaneous combustion polluted air or cause fire, atmosphere pollution, coal gangue air storage meeting produces a large amount of airborne dusts, and this is mainly due to after the coal gangue at ground stacking exposed to the sun and rain for a long time, will weathering pulverize, in addition, meeting disintegration after coal gangue water suction, thus be easy to produce dust, under the effect of wind-force, will worsen the quality of mining area atmosphere.
Summary of the invention
The object of the invention is to overcome weak point in prior art, a kind of coal gangue compound foaming agent is provided.
Coal gangue compound foaming agent is made up of colliery powder, 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 gangue compound foaming agent: first will stir as paste in coal gangue compound foaming agent paste batching input low-speed mixer, then will stir the finished product for coal gangue compound foaming agent in coal gangue compound foaming agent batching input homogenizer.
In coal gangue, the total content of silicon-dioxide, ferric oxide, aluminium sesquioxide is more than 80%, and it is a kind of natural clayey raw material; Although coal gangue calorific value is lower, carbon content is 20～30%, the product that utilizes coal gangue to produce, in roasting process, the combustiblematerials in coal gangue burns, a large amount of holes will be generated in product, be conducive to alleviate the weight of product, improve the fire-retardant and soundproof effect of product, the coal gangue that spontaneous combustion or hand-firing cross, having certain activity, is a kind of active addition.
The Attapulgite potter's clay powder with air purification function is made up of the sticky attapulgite clay of height, attapulite constant humidity amendment, natural-minerals adsorptive filter medium, Leafy twigs of Oriental Arborvitae, aluminium silicate fiber peacekeeping polyacrylamide; there is good cohesiveness, plasticity-, thixotropy, resistivity against fire and thermostability; the effectively objectionable impurities such as formaldehyde, ammonia and benzene in absorbed air, protection of the environment and promote the healthy of people.
High sticky attapulgite clay is the attapulgite clay that adopts the complete processing that improves viscosity of attapulgite clay to produce, attapulgite clay soil property exquisiteness, there is oily soapy, light weight, property are crisp, fracture is conchoidal or irregular shape, and water-absorbent is strong, tool viscosity and plasticity-when wet, more than its viscosity can reach 3000mPas, be conducive to the bonding between raw material.
High sticky attapulgite clay powder refers to gets 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, suspension cup is placed on homogenizer, under the rotating speed of 11000 revs/min, stir 20 minutes, to pour in the beaker of 250ml through high-speed stirring sample suspension again the viscosity that uses NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value>=2200 into
mPasattapulgite clay powder.
Hydrogen peroxide is commonly called as hydrogen peroxide, outward appearance is colourless transparent liquid, be a kind of strong oxidizer, the present invention selects massfraction >=35% of industrial hydrogen peroxide, after mixing, understands a large amount of bubble of generation with colliery powder and the batching such as Attapulgite potter's clay powder with air purification function.
Dimethyl dodecyl amine oxide is a kind of amphoterics, colourless transparent liquid, for weak cation tensio-active agent, in acidic medium, be cationic, in alkaline medium, be nonionic, have good thickening, antistatic, soft, foam enhancing and detergency ability, foam is abundant and stablize, the gentle pungency of character is low, has good static resistance and flexibility.
Cocounut oil acyl diethanolamine is water-soluble, has good decontamination, emulsification, foaming, steady bubble, dispersion, solubilising.
Silicone resin polyethers emulsion is a kind of novel high polymer suds-stabilizing agent, put in order by changing intramolecule, make to arrange between tensio-active agent bubble and bubble closely neat, thereby form fine and close inner layer film, make anti-pressure ability strong especially, can control the structural stability of air bubble liquid-membrane, make the liquid film Methodistic distribution of surfactant molecule at bubble, give elasticity and the self-reparing capability of have good lather, thereby reach desirable especially steady bubble effect.
Polyether modified silicon oil is the organosilicon nonionogenic tenside that adopts a kind of unique properties that polyethers and dimethyl siloxane graft copolymerization forms, and can reduce internal friction, the stress of its molecule, thereby play levelling, froth breaking for the present invention.

When simple use hydrogen peroxide foaming, generation bubble is very fast, but it is also fast that part bubble breaks and disappears, cause the less stable of foam, the present invention is a kind of compound foaming agent, coal gangue compound foaming agent paste generating portion bubble in process of production, coal gangue compound foaming agent is again to foam on coal gangue compound foaming agent paste basis, there is foaming power strong, foam expansion is high, unit volume bubble production volume is large, abscess is fine and smooth evenly difficult broken, product stripping speed is fast, the feature that surface smoothness is good and product later strength is high.
The Attapulgite potter's clay powder with air purification function is glued the raw materials such as the wilkinite after the rice hulls after attapulgite clay, quick dissolved sodium silicate, zeolite powder, acidifying, the zeolite after acidifying, Concavo-convex excellent stone clay after the acidify, acidifying, the coal gangue after acidifying, volcanics, alumine, Leafy twigs of Oriental Arborvitae, aluminium silicate fiber peacekeeping polyacrylamide and forms by height; There is good cohesiveness, plasticity-, thixotropy, resistivity against fire and thermostability, the effectively objectionable impurities such as formaldehyde, ammonia and benzene in absorbed air, protection of the environment and promote the healthy of people.
In the present invention, adopt the Attapulgite potter's clay powder with air purification function for being mainly raw material, produce coal gangue compound foaming agent, given full play to the effective efficiency of Attapulgite potter's clay powder.
The partial invalidity air pocket that adopts polyether modified silicon oil to eliminate in the present invention to produce in production process, and can improve the speed of product stripping, to guarantee the quality of integral foam process.
The product that uses coal gangue compound foaming agent to produce, not only has the effect of insulation, heat insulation, sound insulation, the function purifying air in addition; These products are for facilities such as motorway, viaduct, urban light rail, subway, factory, warehouse, public places.
Coal gangue compound foaming agent is applicable to produce light weight board, Light Wall and sound-deadening and noise-reducing product.
