Description
Technical field
The present invention relates to waterproof material technical field, exempt to soak waterproofing slurry and its preparation side more particularly, to one kind
Method.
Background technique
Waterproofing slurry is a kind of bi-component waterproof material for being exclusively used in buildings waterproof, presses one by powder part and liquid material part
Certainty ratio proportion composition.The waterproofing slurry used is fitted up by Modern Family in waterproofing slurry, and generally K11 type polyalcohol cement basis is anti-
Water slurry, K11 water-repellent paint are called the high-grade waterproof material of K11, are a two-component products, are made of liquor and pulvis, knot
Close polymer modification composite water-proof slurry made of emulsion polymerization and inorganic powder modulation.Powder is by high-quality water
Mud, classified quartz sands and unique high molecular polymer composition, while basal plane is formed whole consistent with dual waterproof efficacy
Integration.
The universal waterproofing slurry of K11 is that house ornamentation circulates most extensively in the market, one of most commonly used water-repellent paint.K11 is general
Type waterproofing slurry can construct in moist region, can resist high hydrostatic pressing, have the function of negative water surface waterproof, be easy behaviour
Make, only needs Site to can be used, wearability is good, and caking property is good, and suitable glue for tile can be used after solid and paste various decorations
Furring tile, waterproof layer can prevent moisture, salinity pollution, inhibit fungus growth, keep good gas permeability, nontoxic, harmless, can be auxiliary
It helps for fishpond and pond etc.；In addition, K11 waterproofing slurry has the characteristics that osmosis type and overlay film type waterproof material, appreciation is in Gu
The waterproof raw material of plate is equipped with extremely strong infiltrative organic-inorganic material using hydrophobic high molecular polymer as essential element, activity
Pore, micro-crack and the chemistry because of explosion that element can penetrate into cement basal plane change, and combine together with ground and constitute one layer
The waterproof layer of compact crystallization, block water via reaching the anti-aqua index of bulking property.
But the universal waterproofing slurry of K11 at present on the market all must first soak basal plane and construct again, working procedure
It is cumbersome, if seriously affecting waterproof effect being then easy to appear shrinkage cavity without soaking or soak the construction of non-uniform basal plane；It is soaking
It constructs in incomplete situation, since basal plane water absorption rate is big, the film moisture after construction is rapidly absorbed, and cause levelability poor,
Film is uneven, the irregular problem of waterproof effect.In addition, also the generally existing open hour are short for the universal waterproofing slurry of K11,
The shorter construction time makes construction be unable to reach optimum efficiency, so that construction quality is severely impacted,
Therefore, before the so big universal waterproofing slurry market plane of K11 of occupation rate of market, change traditional construction party
Formula accomplishes to exempt from wetting construction, shorten the construction period, improving construction efficiency is very important.
Summary of the invention
The present invention is directed to overcome at least one defect of the above-mentioned prior art, one kind is provided and exempts to soak waterproofing slurry, it can be with
Realization exempts to soak basal plane, shortens the construction period, and improves construction efficiency.
