Abstract
A self-reparing flexible water-proof material is prepared from rigid aggregate and water-soluble high-molecular polymer through mixing. Its advantages include high water-proof effect, low cost, no pollution and simple preparing process and application.
Description
Self-repairing flexible water-proof material and manufacture method thereof belong to field of waterproof materials.
Present roof waterproof, coiled material accounts for 80% of whole water-proof material, along with the develop rapidly of science and technology, though constantly bringing forth new ideas its flexibility as the tire of traditional waterproof roll-asphalt water-proof coiled material is fine, unit elongation, draw intensity and durable, weathering resistance is all not ideal enough, be difficult to the distortion situation that acclimatization alternately reaches buildings, through scientific and technical personnel's big quantity research, the persistence of water-proof material has had raising in various degree, but the construction process requirement strictness, cost rises successively.Using another big problem of waterproof roll is that the sizing of coiled material and substrate is the main body material with pitch mostly, the gas serious environment pollution that distributes during construction, be detrimental to health, the more important thing is that the construction difficulty that puts in place is very big, even can not put in place sometimes, causing seepage to be inevitable.Its objective requirement meets the prerequisite of construction: " drying, cleaning, temperature are suitable ", subjectivity require strict construction again, and be so harsh, is difficult to accomplish that coiled material lays the no air bound in back, the fragility of material and construct in gap, be difficult to reach design requirements.In order to address the above problem, through the Chinese patent retrieval, existing people develops hydrophobe, mostly is aggregate with the light calcium carbonate, and then, the calcium grain is coated by lyophobic dust (wax, long chain fatty acid), produces to refuse the water effect.Though these hydrophobe simple grains are refused water, every the water scope of refusing is limited, the sieve drop ply that forms by such hydrophobe, in case sieve leaks, it is irresistible just to leak gesture.As " Chinese patent " application number: 91100628, the applying date: 91.02.05, Granted publication day: 93.07.07, applicant: Branch of Beijing Normal College, denomination of invention: flyash hydrophobic powder and production method thereof, this flyash hydrophobic powder and production method thereof, be based on flyash, organosilicon polymer or silicone oil material are by sapn, the silicone oil emulsion that emulsifying agent emulsifications such as tween form is as auxiliary agent 1, with amine substance or enol class material polymkeric substance as auxiliary agent 2, the composite emulsion of two kinds of auxiliary agent formation infiltrates the effective constituent of flyash through reacting by heating and flyash, forms reticulated structure and refuses moisture film.The subject matter that exists is to produce to use complex process, still causes environmental pollution, cost height.And for example: " Chinese patent " application number: 89105467, the applying date: 89.01.30, Granted publication day: 90.08.15, applicant: Tongji University, denomination of invention: building waterproofing powder and production method thereof, this building waterproofing powder and production method thereof, utilize the characterization of adsorption of solid powder, adopt process for treating surface to produce building water-proof powder, with the inorganic powder is base material, add water and be made into slurry, the ξDian Wei that adds auxiliary agent adjusting powder then makes it electrically to be complementary with ionogenic surfactant.Slurry is with after tensio-active agent mixes, and through fully stirring, tensio-active agent is stabilized the ground oriented adsorption on the inorganic powder surface, after drying, can obtain the building water-proof powder of tool hydrophobic nature, and this water-proofing powder can use separately.The problem that this water-proofing powder exists remains complex manufacturing, the cost height.
Purpose of the present invention just is to overcome the deficiencies in the prior art, provide a kind of good water-proof effect, cost value low, pollution-free, make and use simple self-repairing flexible water-proof material of technology and manufacture method thereof.
The objective of the invention is to realize in the following way:
This self-repairing flexible water-proof material is characterized in that: comprise rigid backbone material and high molecular weight water soluble polymer.
Purpose of the present invention also can realize in the following way:

Described rigid backbone material is: one or more in loess, sand, stone flour, flyash, land waste, slag, perlite, the vermiculite, preferred sand, loess, slag.
Described high molecular weight water soluble polymer is: one or more in polyvinyl alcohol (PVA), polyacrylamide (PAM), urethane (PU), polypropylene acid (PA), polyoxyethylene glycol (PEG), polyoxyethylene (PEO), water-soluble silicon gel (CK-40), ether of cellulose, the treated starch, preferably polyethylene alcohol PVA, polyacrylamide PAM.
Described ether of cellulose is: one or more in Walocel MT 20.000PV (CMC), sulfonic acid ethyl cellulose (SEC), methylcellulose gum (MC), methylol methylcellulose gum (HBMC), hydroxypropylcellulose (HPC), the cyanoethyl cellulose (CEC), preferred Walocel MT 20.000PV (CMC), methylcellulose gum (MC).
Described treated starch is: one or more in phosphate ester starch (PSS), the hydroxymethyl starch (CMS).
Described additive is a tensio-active agent, mainly be: one or more in glycol fatty acid ester (EMCOLEO-50), fatty alcohol-polyoxyethylene ether (UKANIL), the polyethylene Viscotrol C (TRYLOK-40), preferred glycol fatty acid ester (EMCOLEO-50), shared weight proportion is 0.1-2.
This self-repairing flexible water-proof material by weight ratio, sand: polyacrylamide (PAM) be 100: 2 for preferred plan.
Another object of the present invention is to adopt as the realization of getting off:
The manufacture method of above-mentioned self-repairing flexible water-proof material, at first the rigid backbone material is crushed to the 30-100 order, weight proportion according to the above ratio adds 60-150 purpose high molecular weight water soluble polymer, mix, or add water and be mixed into the mud formation waterproof layer of constructing, thickness 0.1-10cm protects with sand-cement slurry in the above again.
The inventive point of self-repairing flexible water-proof material of the present invention mainly is to add high molecular weight water soluble polymer in the rigid backbone material, make a kind of new water-proof material, this water-proof material forms the flexible membrane that is made of anti-certain hydraulic pressure framework material and hydrogen-bonded chain jointly after meeting water, this film has antiseep and seepage self-healing ability, overcome in the prior art waterproof and utilized hydrophobic substance exactly, can not use the technology prejudice of hydrophilic substance, and produced beyond thought effect, as: very hard after the drying, has intensity preferably, as the rapid deliquescing that occurs leaking forms a skim, powdery can at will spread in the crack in addition and small pin hole in, and can repeat to pulverize and use, has good water-proof effect, the material cost price is low, pollution-free, self-healing ability is strong, making advantages such as using method is simple, is present optimal a kind of waterproof material.
