Abstract
The present invention relates to a waterproof heat-insulating emulsion and a production process thereof, which belongs to the technical field of construction and agriculture. The present invention achieves the purposes of water prevention, heat insulation, the reformation of saline-alkali soil, the prevention of soil salinization, etc. The waterproof heat-insulating emulsion is characterized in that the solvent type emulsion is manufactured by the polyreaction of industrial waste slag (pulverized coal ash or coal gangue powder), stearic acid, polyvinyl acetate and polyisocyanate. The emulsion with thickness of three millimeter is poured on a base layer and is smoothed in time; after the emulsion is dried, the function of water prevention can be performed; a glass fiber cloth is paved on the base layer, and the emulsion with thickness of ten millimeters is poured on the glass fiber cloth; after the emulsion is dried, a flexible waterproof heat-insulating roof covering is formed. The emulsion is suitable for the engineering of the water prevention of constructions, the fertilizer maintenance of agricultural sandy soil, the prevention of soil salinization, etc.
Description
The invention belongs to building material technical field.
The kind of water-proof heat-insulation material that is applied to construction work at present is a lot, as: with pitch the metal species water-resisting agents such as waterproof paint, coiled material, ointment, muriate and inorganic aluminate, water-proofing powder of base material and with epoxy resin water-proof material etc.Adopt filled asbestos, expanded vermiculite, perlite, rock wool and organic plastics foam etc. more in heat-insulation and heat-preservation material the inside.(seeing " material of construction handbook "---China Construction Industry Press for details).
Above-mentioned these materials all obtain application in various degree in construction work, and have certain waterproof or heat insulating effect.But because these material majorities can not have both not only waterproof but also heat insulation function, and material price is higher, production technique is complicated.The hydrophobic powder for building (patent No. CN87101009) that occurs in recent years and for example is used for the waterproof and dampproof of building roof, platform, pond, and its performance is better, but because the construction dust is wayward and labour intensity is bigger, the numerous and diverse and difficult popularization of operation.
Purpose of the present invention: be construction waterproofing engineering, a kind of effectively production method of water-proofing and heat-insulation emulsion of high quality and at a reasonable price is provided.
This technology is for solving not only waterproof reliably but also heat insulation good, the major technique feature be this product be raw material with the industrial residue through and stearic acid, polyvinyl acetate (PVA), ethanol and polyisocyanates emulsion are mixed and are made serum.If the serum of pouring 3 mm thick in basic unit, and in time use grey cutter floating, get final product water proof after waiting to solidify, or isolate with glass cloth and basic unit, promptly at basic unit's upper berth glass cloth, and water the serum of 10 mm thick thereon, solidify the back flexible water proof heat-insulated roof, also can adapt to single ply roofing, and can paste firmly with basic unit.Be applicable to construction waterproofing engineering.
Production method of the present invention: be fineness to be dropped in the reactor less than the flyash of 50 μ m or colliery powder heat up, under constantly stirring, add stearic acid, and be warming up to 150 ℃, through physical reaction, it is stirred, to be cooled after 25 ℃, add polyvinyl acetate (PVA) and ethanol more simultaneously, still need stir, and add the polyisocyanates emulsion therein, it is stirred, promptly make water-proofing and heat-insulation emulsion.Store with container.Temperature reaction process characteristic, melted stearic acid is wrapped in the micro powder granule top layer equably, and micro powder granule is disperseed.
Its serum of this production method by the mixing ratio by weight of material is: flyash or colliery powder: stearic acid: ethanol: polyvinyl acetate (PVA): polyisocyanates=1000: (25～50): (800～1000): (200～400): (40～80).The fineness of its flyash or colliery powder is less than 50 μ m.
Can be widely used in the waterproof and heat-insulating engineering of building roof, warehouse, vault lining cutting by the serum of present method production, and the water proof percolating work of pond, tunnel-liner, have anticorrosive, heat-resisting, cold-resistant, acid and alkali-resistance, do not burn, characteristic such as pollution-free and life-time service never degenerates.And be raw material with the industrial residue, can not only reduce the harm of waste residue to environment, turn bane into boon, and also the low price of product, abundant raw materials, production technique is easy, need not add strongthener, and is safe in utilization, to the person poultry harmless.
Advantage that serum had or effect that the present invention produces:
1. weathering resistance is strong, characteristic such as have anticorrosive, acid and alkali-resistance and do not burn;
2. stable chemical performance is not subjected to the influence of the various compositions of atmosphere, and environment is not polluted, and does not have the harm of secondary slag source;
3. heat-resisting, cold tolerance is good, and its inside, the fixed back of product is the cellular-shaped structure of foam, and its heat insulation effect is good, uses to 90 ℃ of conditions of high temperature at-30 ℃, and destruction undergoes no deterioration;
4. easy construction can independently use, and is not subjected to the influence of basic unit's humidity, both can make built-up roofing, also can adapt to single ply roofing, and can paste firmly with basic unit;
5. raw-material source is abundant, and it is cheap, is easy to big area and promotes.
Description of drawings:
Accompanying drawing---water-proofing and heat-insulation emulsion technological process of production figure.
Embodiment:
Example 1. is by weight preparing burden: flyash or colliery powder: stearic acid: ethanol: polyvinyl acetate (PVA): polyisocyanates=100: 4: 90: 25: 6.Wherein flyash is the electronic dry ash that gathers dust in power station, and particle fineness is less than below the 50 μ m; Stearic acid, ethanol, polyvinyl acetate (PVA) and polyisocyanates are commercially available.
In reactor, put into 100 kilograms of flyash, add 4 kilograms of stearic acid when under constantly stirring, being warming up to 80 ℃, continue to stir and be warming up to 150 ℃, make the stearic acid fusing and react the back cooling, when treating that temperature is reduced to 25～30 ℃, under agitation 90 kilograms of ethanol and 25 kilograms of polyvinyl acetate (PVA) are added in the reactor, obtain emulsified paste, add 6 kilograms of polyisocyanates again and stir, promptly make water-proofing and heat-insulation emulsion.
2. pairs of examples are new, when old roof carries out WATER REPELLENT, can directly in basic unit, water the water-proofing and heat-insulation emulsion of 3 mm thick, and in time use grey cutter floating, get final product water proof after the curing, perhaps isolate with glass cloth and basic unit earlier, the water-proofing and heat-insulation emulsion of pouring 10 mm thick on glass cloth is promptly made flexible water proof heat-insulated roof after the curing again.
