The invention discloses a novel flexible waterproof gum coating for stone. The coating is prepared by mixing the following components in percentages by weight: 10 to 50 percent of acrylic emulsion, 0.01 to 2 percent of a water reducing agent, 0.01 to 2 percent of a thickener, 0.01 to 2 percent of a defoamer, 5 to 60 percent of cement, 5 to 60 percent of silica sand and 5 to 60 percent of heavy calcium, wherein the acrylic emulsion is preferably a low-Tg pentabasic copolymer emulsion of a core-shell structure. The novel flexible waterproof gum coating for stone disclosed by the invention is good in flexibility, fluidity and stability, the caking property of stone and cement surfaces is improved, and the phenomena of efflorescence, waterlogging, bulking, cracking and the like are effectively prevented.
Description
Technical field
The present invention relates to stone material gum technology, particularly relate to a kind of Novel stone flexible water gum coating.
Background technology
Based on two component gums of water-based emulsion and inorganic salt silicate, substitute traditional unsaturated polyester resin on a large scale.Waterproof gum is relative to unsaturated polyester resin, and not only environmental protection smell is little, and no longer needs to root out back of the body stratum reticulare, greatly reduces the damaged degree of stone material.When adopting wet combining construction, the compatibility of back face of stone and cement based adhesive is poor, easily occurs flaking, hollowing, to come off and the phenomenon such as cracking.If the improper use of water-based stone material gum, stone surface also can be caused to produce the white problem such as magnificent, water stain.It is good that water-based stone material gum needs with cement based adhesive consistency, and ensure that obscission can not occur stone material, water-based stone material gum also needs certain flexibility, reduces the generation of stress.
When the Tg of acrylic ester emulsion is lower than 0 DEG C, time especially lower than-10 DEG C, 5 joining property of emulsion and cement are poor, the mobility of stone material gum coating can be caused to be deteriorated, not easily construct, cause stone slab to glue shaky.
Summary of the invention
The object of the invention is a kind of Novel stone flexible water gum coating proposed for the deficiencies in the prior art, the ACRYLIC EMULSION of this coating selection nucleocapsid structure, the problem of low Tg emulsion and cement poor compatibility can be solved, introduce a kind of thickening material simultaneously, the mobility of stone material gum coating can be controlled preferably, to overcome the problem of consistency that existing Waterproof gum coating occurs and mobility.
