Description
The invention belongs to construction work and agricultural technology field.
The kind of water-proof heat-insulation material that is applied to construction work at present is a lot, as: with pitch is metal species water-resisting agent, the water-proofing powder such as waterproof paint, coiled material, ointment, muriate and inorganic aluminate of base material; With 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.
At agriculture field to the transformation of salt affected soil with prevent the soil salinization, global major issue really, many modification methods of current employing have all been obtained certain effect as: water conservancy, agrotechnical, chemistry etc.Some countries once adopted the manufacturing sealing coat, and the liquid manure on be used to improve the soil salinification and sandy soil ground keeps, and its effect is excellent, but because costing an arm and a leg of these measures and can't big area promoting.
Purpose of the present invention:, provide a kind of effectively water-proofing and heat-insulation emulsion and production technique thereof of high quality and at a reasonable price for the liquid manure on the improvement in waterproof insulation engineering, agriculture saltings, sandy soil ground keeps and desert afforestation is built up fields etc.
This technology is for solving not only waterproof reliably but also heat insulation good, and the transformation of salt affected soil and prevent problem such as the soil salinization, the major technique feature is that this product is that main raw material is through making the solvent-borne type serum with stearic acid, the poly-rare ester of acetic acid second and polyisocyanates emulsion polymerization with industrial residue (flyash or colliery powder).If the serum of pouring 3 mm thick in basic unit, and in time use grey cutter floating, get final product water proof and heat insulation 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 that construction waterproofing engineering, agriculture sandy soil ground liquid manure keep and prevent engineering such as salting of soil.
Production technique of the present invention: flyash or colliery powder (fineness is less than 200 orders) are dropped in the reactor, carry out temperature reaction, under constantly stirring, add stearic acid, and be warming up to 150 ℃, behind chemical combination, physical reaction, become emulsifying aq, it is stirred, to be cooled after 25 ℃, add poly-rare ester of acetic acid second and ethanol more simultaneously, still need stir, and add the polyisocyanates emulsion therein, it is stirred, promptly make the water-proofing and heat-insulation emulsion product.Store with container sealing.
Temperature reaction process characteristic, the Calcium of intensifiens in its micro mist, al composition and stearic acid react, and generate calcium stearate [CH
3(CH

16COO]
2Ca and aluminum foil stearate [CH
3(CH

3Al, the hard ester acid of resultant of reaction and melting is wrapped in the micro powder granule top layer equably, makes micro powder granule hydrophobic and dispersion.To be cooled after 25 ℃, add poly-rare ester of acetic acid second and ethanol, form hydrophobic emulsion, add polyisocyanates again and make water-proofing and heat-insulation emulsion as the solidifying agent of poly hydroxyl compound.
This technology by the mixing ratio by weight of material is: flyash or colliery powder: stearic acid: ethanol: the poly-rare ester of acetic acid second: polyisocyanates=1000: (25～50): (800～1000): (200～400): (40～80).The fineness of its flyash or colliery powder is less than 200 orders.The serum product of making is the solvent-borne type serum; Also can be made into the water proof thermal insulation plate, its light weight, porous become foam honeycomb shape structure; After being evaporated as the solvent of solvent-borne type serum, again it is ground into fine powder, promptly makes the water proof powder.
This serum product can be widely used in the waterproof and heat-insulating engineering of building roof, logical sequence storehouse, vault lining cutting, and the water proof percolating work of pond, tunnel-liner, also can be used as the sealing coat that agriculture salt affected soil improvement, the maintenance of sandy soil ground liquid manure and desert afforestation are built up fields etc.That this product also has is 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 main 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 the present invention had or effect:
1. weathering resistance is strong, characteristic such as have anticorrosive, acid and alkali-resistance and do not burn;
Stable chemical performance, be not subjected to the influence of the various compositions of atmosphere, and environment is not polluted, does not exist the harm of secondary quarrel source;
3. heat-resisting, cold tolerance is good, after product was fixed, its inside was foam honeycomb shape structure.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, makes sealing coat, improvement salt affected soil and liquid manure and keep on agricultural, 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: stearic acid: ethanol: the poly-rare ester of acetic acid second: polyisocyanates=100: 4: 90: 25: 6, wherein flyash was the electronic dry ash that gathers dust in power station, and granularity is below 200 orders; Stearic acid, ethanol, the poly-rare ester of acetic acid second 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 rare esters of poly-acetic acid second are added in the reactor, obtain emulsified paste, add 6 kilograms of polyisocyanates again and stir, promptly make the water-proofing and heat-insulation emulsion product.
2. pairs of examples are new, when old roof carries out waterproof thermal-insulated processings, the direct water-proofing and heat-insulation emulsion of pouring 3 mm thick in basic unit, and in time use grey cutter floating gets final product water proof after the curing, perhaps use the isolation of glass cloth and basic unit earlier, waters on glass cloth again
The water-proofing and heat-insulation emulsion of 10 mm thick is promptly made flexible water proof heat-insulated roof after the curing.
