Description
The invention belongs to building water-proof powder and production method thereof.
Seek the technology that solves waterproof construction, leakproof, antiseepage, protection against the tide satisfactorily and be still people's question of common concern.At present, building waterproofing technique mainly contains asphalt waterproofing, mortar waterproof, coating waterproofing, sheet material waterproof, and the water-proof material that is applied to construction work comprises waterproof roll, waterproof paint, sealing cement, water-resisting agent.
The waterproof paint of forming by hydrophobic metal or nonmetal oxide and polyvalent alcohol (US4,102,703); Water-resisting agent of forming by basic metal alkyl or silicic acid phenyl ester complex compound and monohydroxy-alcohol or ketone (US3,955,985) and domestic existing waterproof paint, water-resisting agent, waterproof roll; The building water-proof powder that the Soviet Union makes with the bituminous treatment boiler ash sediment fifties, though they can solve the waterproof and dampproof problem of construction work to a certain extent, generally lose waterproof action and can not remedy and solve building structure automatically and be out of shape, shrink the basic crack infiltration that causes because of material aging.And because these water-proof material prices are higher, production technique is difficult to apply than complexity.
In recent years, succeed in developing new powdered architectural waterproof material, though trade name is different, its essence all is the powder with hydrophobicity performance, the general designation water-proofing powder.Building water-proof powder and production method thereof that domestic patent of invention (application number is 87101009.A, 89105467.7,90102869.X, 90105847.5,90106731.8,90106796.2,90107668.6,91104534.1,91105131.7) proposes, this water-proofing powder respectively has advantage to the existing Gai Jin And of aforesaid water-proof material, but also has following shortcoming:
1. the slurry of forming by inoganic solids powder, hydrophobic nature material, sodium hydroxide and water, its liquid-solid ratio is higher or on the low side so that waste raw material, power source or stir difficulty, hydrophobic film is inhomogeneous.And slurry heats up, and especially requires the interior Yan Mo And of ball milling to heat to 60～100 ℃, and its technology is rationally also complicated inadequately.
2. the hydrophobic nature material is single, and the choice is little; Adopt ethanol, organosilicon sodium alkoxide, tensio-active agent etc. to increase raw materials cost.Simultaneously, useful component reclaims difficulty, and, to adopt high-temperature calcination sometimes, increase facility investment.
3. with the single hydrophobic nature material of paraffin wax emulsion, its poor chemical stability; The dehydration slurry will reach the water-proofing powder water ratio below 1% 60 ℃ of dryings, and the actual drying time is oversize; Organosilicon sodium alkoxide method will be heated in the carbonic acid gas baker to 70～90 ℃ and be carried out reaction and drying, is difficult to suitability for industrialized production.
The objective of the invention is to the foregoing invention patent is improved, particularly the selection and the technological process of hydrophobic nature material are improved, provide the compound construction waterproof powder that a kind of cost is lower, production technique is simple, product performance are reliable, easy to use, to solve the moistureproof problem of building waterproofs such as roofing, platform, water tower, warehouse, freezer, mine aisle, vault, toilet, leakproof, antiseepage and wall.
Another object of the present invention is to; base material as water-proofing powder; except that calcium lime powder, light calcium carbonate powder; can utilize natural rock breeze, fine sand, industrial residue, alunite waste residue in a large number, help economizing on resources utilize resources synthetically; the disposal of three wastes and protection environment; particularly utilize the alunite industrial residue, for promoting that the industrial development of alunite chemistry is highly significant with practical value, this is that patent of invention did not have proposition in the past.
Mechanism of the present invention is, the composite water-proof powder is a core with inoganic solids powder fine particle, extexine is evenly surrounded by hydrophobic film, making the powder surface modification is hydrophobic nature, thereby have a water repellency, and gather by the pulvis that cohesion effect is formed entity that certain granules intensity and stability are arranged-have water-repellancy and to constitute powder group waterproof layer.Simultaneously, owing to have certain natural porosity not have tensile stress between the loose mutual NA water-proofing powder particle,, reach the purpose of waterproof, leakproof, antiseepage, protection against the tide as long as powder surface hydrophobic just can cut off water osmosis capillaceous.
Production method of the present invention is:
The raw material of water-proofing powder of the present invention is made up of inoganic solids powder, hydrophobic nature material, sodium hydroxide, water, their weight proportion of composing is 100: (2-10): (0.2-0.8): (200-500), the inoganic solids powder is made up of a kind of in calcium lime powder, natural rock breeze, light calcium carbonate powder, fine sand, industrial residue, the alum waste residue or two kinds and above mixture thereof, and the hydrophobic nature material is two kinds or three kinds of compositions in rosin or rosin, stearic acid, the paraffin.Its production method is:
With rosin pulverize And be added to heat concentration be in the sodium hydroxide solution of 0.2-0.8%, constantly stir, after treating that rosin melts substantially, add stearic acid, paraffin, form emulsion, reusable heat water and room temperature water dilution ， And add inoganic solids powder (embodiment 1 calcium lime powder) in the emulsion slowly, and full and uniform stirring forms slurry.Then, slurry filtration and dewatering, bake drying, crushing screening are obtained compound construction waterproof powder.
Production method process of the present invention has two kinds of effects, and realizes in same technological process.
(1) chemical reaction
(2) adsorption surface modification
Inoganic solids powder surface is formed the layer of even hydrophobic film by hydrophobic nature material adsorption of modification, makes powder have water repellency.
Water-proofing powder of the present invention is applicable to the moistureproof problems of waterproof, leakproof, antiseepage and wall such as solving new and old building thing roofing, platform.
The present invention has the following advantages:
(1) product appearance is a fine powdered, odorless, tasteless, nontoxic.
(2) chemical reaction and the adsorption of modification of production safety, easy, the solid liquid phase of technology are realized in same process single stage method, are easy to suitability for industrialized production, low equipment investment.
(3) product performance are stable, do not wear out, never degenerate, indeformable, decrement not, and long service life is not influenced by ultraviolet ray.
(4) product has diversity, good fluidity.When there is the crack in buildings basic unit, because water-proofing powder deadweight effect, joint filling crack automatically can fall, so this water-proofing powder is not influenced by basic crack, waterproof action is effective, easy construction, saving of work and time, simultaneously, the product thermal conductivity is little, do not burn, unit weight is light, has heat insulation, insulation, flame retardant properties.
(5) utilize natural rock breeze, industrial residue and alunite waste residue; raw material sources are extensive, favourable energy-conservation, the utilization of resources, the disposal of three wastes, protection environment, and technology itself does not produce the three wastes; production cost is low, has remarkable social benefit and economic benefit.
