Abstract

The present invention discloses waterproof anti-seepage glue A and waterproof anti-seepage glue B, wherein the glue A is prepared from acrylic acid, polyurethane and filler, and the glue B is prepared from styrene, methacrylic acid, polyvinyl alcohol, vinyl acetate and an auxiliary agent. One portion of the waterproof anti-seepage glue B and 1 to 2 portions of silicate cement are uniformly stirred and mixed to be prepared into pasty glue paste in use; the glue paste is uniformly coated on a smooth waterproof base surface by 2 to 6 times by a hair brush or other coating equipment, the surface of every square meter is coated with 0.5 to 1.5 kilograms of the glue paste, and the surface does not need special maintenance. The waterproof anti-seepage glue is adopted, so the density of cement can be strengthened for realizing the functions of water prevention and seepage resistance, and the strength and the adhesive force of the cement can be enhanced by more than two times.

Description

Water proof anti-seepage glue and water-preventing impervious method

The present invention relates to a kind of water proof anti-seepage composition and water-preventing impervious method, specifically, the present invention relates to a kind of water proof anti-seepage seccotine and adopt the method for this water proof anti-seepage seccotine water proof anti-seepage.

General roof, roofing, toilet, vault and various pipeline, storage tank need carry out WATER REPELLENT, in the prior art, the material that is used for WATER REPELLENT mainly contains pitch, modifying asphalt, ternary ethylene-propylene copolymer and polyurethanes, and constructional method has hot melt paving, cold bonding, films etc.

Though aforesaid way respectively has advantage, all exist construction trouble, water-repellancy difference or problem of ultra-high price.

The object of the present invention is to provide a kind of environment-friendly type water proof anti-seepage composition, said composition has good waterproof impervious characteristic.

Another object of the present invention is to provide a kind of method of water proof anti-seepage, and this method is simple, convenient, the good combination property of water proof anti-seepage.

To achieve these goals, the invention provides the impervious glue of a kind of flexible water, it is characterized in that filling a prescription and consisting of:

A. vinylformic acid 28-40%

Urethane 3-10%

Mica powder 8-12%

Zinc sulfide white 15-25%

Titanium dioxide 10-17%

Pure aluminium silicate 8-12%

Dibutyl phthalate 1-5%

Polyoxyethylene octylphenol ether 1-5%

Above-mentioned raw materials and prescription are formed the impervious seccotine of flexible water, are used for the flexible water engineering, during use, can directly sizing material be poured in the smooth basic unit, brush, sizing material is linked together with scraper plate or brush, after treating the first pass surface drying, be coated with again second time, with reference to consumption: 1-1.5Kg/m2.

In addition, the present invention also provides a kind of rigid waterproofing impervious glue, it is characterized in that filling a prescription and consisting of:

B. vinylformic acid 20-30%

Vinylbenzene 3-8%

Butyl methacrylate 3-8%

Polyvinyl alcohol 40-50%

Vinyl-acetic ester 10-15%

Tributyl phosphate 0.1-0.5%

Polyacrylic acid dipersant 2-5%

MALEIC ANHYDRIDE 0.5-1.5%

Sodium sulfonate Viscotrol C 0.2-1.0%

Antiager 0.01-0.03%

During use, with the impervious glue B of above-mentioned rigid waterproofing and No. 425 or above label ordinary Portland cement, according to 1: the ratio of 1-2 mixes, become the pasty state rubber cement, with hairbrush or other coating devices evenly brushing smooth waterproof basal plane 2-6 time, every square meter consumption 0.5-1.5 kilogram need not special curing; If desired, can impose the impervious glue A of flexible water earlier, impose the impervious glue B of rigid waterproofing more thereon,, can directly on waterproof layer, paste as the sticking ceramic tile of need at bottom.Since water proof anti-seepage glue of the present invention and the activity that can activate cement after silicate cement mixes, generation low-grade fever amount, thereby the intensity and the bonding force of raising cement concrete.When coagulating cement heat release and water evaporates, concrete hydrophobic molecule and polymer substance produce cohesion for the second time, and density strengthens, thereby reaches waterproof, impervious effect, and cement intensity and bonding force can be improved more than the twice.

Water proof anti-seepage seccotine of the present invention is a kind of nontoxic, tasteless, environment-friendly type, single-component glue.Can replace SBS waterproof roll and Ethylene Propylene Terpolymer to be total to copolymerized water-proof coiled material etc., need not other WATER REPELLENT, make cement can play the effect of water proof anti-seepage, its intensity and life-span are much higher than Portland cement, thereby improved the work-ing life of waterproofing work, greatly reduced the construction costs cost.Can be used for hydro project, road and rail bridge engineering, Tunnel Engineering swimming pool, lavatory bathe between, flexible water engineerings such as buildings roof, vault, be applicable to that in addition marble, slabstone, hard foamed polystyrene board and concrete combination are bonding.

With meet GB175-1992 regulation, 425# ordinary portland cement, standard sand and concrete waterproof special adhesive be by weight 1: 2: (0.4-0.5) be made into rubber cement, repeatedly mix evenly after, leave standstill 10min, the inner conical surface moulding closed place on the sheet glass piece.

The glue mortar for preparing is injected tamping in the mould, after the final set, unload and but remove sheet glass, release the sclerosis rubber cement gently.To harden then, rubber cement is In Shade to dry naturally.Move to behind the 24h under the wet environment, be interrupted to its surface sprinkling, keep moistening, maintenance is to the length of time.Make 6 (two groups) altogether.Every group 3, for the impervious test of 7d.

B. be used for rubber cement and be coated with impervious test

Change mortar in the A method into conventional cement mortar, make the taper hardenite, meet water and the water resistance test if do, then the big face at cone-shaped body stays the thickness of a 1.5mm so that smear the waterproof rubber cement; If do the test of back side water resistance, then change the facet of cone-shaped body into.The taper hardenite of maintenance 7d, seasoning 24h waits to be coated with.

Waterproof glue and 425# ordinary portland cement were mixed with rubber cement by 1: 1, divide and somely go up until reaching thickness 1.5mm all over spreading upon to be measured of taper hardenite to be measured, natural curing 24h just can carry out the water resistance test.

Step

In advance test specimen is dried 12h, test specimen conical surface waxing, die trial place on the electric furnace roasting heat to take off, and take advantage of test specimen that hot pressing goes into waxing until cold, but both ends of the surface forbid to have wax juice to splash into.

With install rubber cement the test block of sealing wax be screwed in the box, test with reference to the GB328.3-1989 associated viscera, the 0.1Mpa of initial pressure, the every 15min 0.1Mpa that boosts when specified Mpa, keeps 1d.Have 2 the seepage phenomenon not occur and be qualified in 3 test specimens, impervious pressure is directly read from tensimeter.

During use, after having smeared screed-coat by design in the structure basic unit, brush six road waterproof glues, dry brushing again after the brushing) weight proportion of waterproof glue is glue: cement 1: 1.2.Do surface layer then, when doing surface layer by glue: 1: 1 weight ratio of cement stir evenly one interfacial agents of brush with brush with plastering.Use glue 1kg for every square metre.Other special engineering can adopt and spray or other constructional method.
