3. superior anti-crack and anti-seepage, can eliminate the dry cracking causing with plasticizing contraction of mortar, not " accumulation of salt in the surface soil ".Anti-permeability strength surpasses 1.0MPa, reaches the effect the same with polymer powder waterproof mortar, cost can reduce near half.
Met following requirement:
(1) can adapt to different walling unit matrix, to being had sufficiently high cohesive strength by sticky substrate surface, the bonding that causes when overcoming construction is not firm, hollowing, the disadvantage such as peel off.And thering is good waterproof, weather-proof, the performance such as " accumulation of salt in the surface soil ", not aging and freeze-thaw-not, permanence operation is very good.
(2) there is high splitting resistance and impermeability.Float coat is firm full, evenly closely knit, and the application of big area wall construction, need not stay and establish expansion joint, there will not be dry shrinkage cracking.Wall coating need not increase steel mesh or is sticked on fibrous reticulum, and other waterproof measure processes, and formed waterproof glued layer is enough to resist the destruction of ultimate stress, cuts off the infiltration of rainwater.
(3) construction is simple, low price.During construction, proportioning is on request adjusted and is mixed, scene adds water and stirs evenly and can use, even if adjust the rubber cement of mixing to surpass 3h duration of service, even adjusts the morning to mix and waits until construction in afternoon, and rubber cement excreting water phenomenon can not occur yet.During operation, body of wall need not water, need not wet curing after wiping one's face, and simple and efficient, comprehensive cost is quite cheap.
In sum, add the sand-cement slurry of multifunctional polymer cement powder mortar additive of the present invention, generate a series of crystal, colloidalmaterial, this crystal is constantly grown up and is pushed to surrounding, compensate and offset the drying shrinkage of cement, obtain the self-repairing capability of micro-cracks and high anti-permeability performance; Colloid enters in the space of cement, greatly improves cohesiveness, density and the anti-fracture toughness property of sand-cement slurry, from being shaped as permanent firm waterproof and adhesive structure.Apply multifunctional polymer cement powder mortar additive of the present invention, there is water-proof repairing, tile bonding, the cracking resistance multi-functional effect such as plaster, and the effect that unites two into one of water-proofing anticracking, tile paste.Can prepare separately water-proof repairing material, waterproof impervious characteristic reaches JC/T 984-2005 < < polymer cement waterproof mortar > > standard; Preparation ceramic tile bond, tile bonding intensity reaches JC/T 547-2005 < < ceramic wall and floor bricks tackiness agent > > standard; And preparation cracking resistance motar etc.And nontoxic, non-stimulated, do not fire, containing organic volatile matter, freeze proof, cracking resistance, anti-aging, water-fast, sun-proof, corrosion-resistant, easy to use, dependable performance, the feature such as cheap, environment friendly and pollution-free.
Above content is in conjunction with concrete optimal technical scheme further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
