Description
Technical field
The present invention relates to a kind of concentrate feed of water-proof material, particularly the multi-functional concentrate feed of a kind of kitchen guarding's cement group water-proofing material, belongs to the water-proof material technical field in building trade.
Background technology
Water-proof material is a kind of important materials in construction safety field, is mainly divided into waterproof roll and the large class of waterproof paint two.Polymer cement waterproof paint is a kind of organic liquid material forming with the polymer emulsions such as polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion and various additive, and the inorganic powder that the mineral filler such as cement, quartz sand, light water-ground limestone and various additive form is by rational proportion, compounded a kind of pair of component, aqueous architectural waterproof paint.Polymer cement waterproof paint be best suited for non-exposure roofing, lavatory bathe between and the waterproof of exterior wall, anti-ly blend moistureproof engineering.
The water-proof material that is applied to kitchen guarding's waterproof construction requires water resistance excellent, good environmental protection.Polymer cement waterproof material has been taken into account the snappiness of polymkeric substance and the weather resistance of cement material, hard and soft combination, and extensively obtain application with the feature of its aqueous, environmental protective.The traditional polymer cement waterproofing material that is applied at present kitchen guarding mainly comprises: flexible excellent polymer cement waterproof paint and partially rigidity are the main large class of polymer cement waterproof mortar two.Polymer cement waterproof paint hydrophobic nature is strong, flexible excellent, but exists the later stage to be difficult to paving ceramic tile, cannot carry out the defect of back side waterproof; Polymer cement waterproof mortar excellent rigidity, but water proof anti-seepage effect is poor, conventionally requires water-proof coating thickness thicker (2cm left and right), for kitchen guarding's construction, has the defect that easily makes kitchen guarding's volume diminish.In addition, traditional cement group water-proofing material is in the majority with two components (powder, liquid separately packing), has complex manufacturing, and liquid material was easily frozen and caused breakdown of emulsion winter, cannot transport, the defect such as shops's display, use.
In the existing relevant report of cement group water-proofing material that relates to kitchen guarding's waterproofing work, above-mentioned defect still fails to obtain basic overcoming.As patent CN101891432 B discloses a kind of penetration crystallization type water proofing paint, by silicate cement, quartz sand, filler, ionic calcium cpd, crystalline deposit agent, complexing auxiliary agent, film coalescence aid, complexing agent, polycarboxylic acids dehydragent, methylcellulose gum forms, this product is by growing and do not dissolve crystal in concrete surface pore and tiny crack, capillary porosity duct and tiny crack are stopped up, thereby improve concrete anti-permeability performance, reach waterproof, the object of leak stopping, though the waterproof paint of this type can obtain good waterproof effect, but its flexibility is poor, patent CN 1952030 B disclose a kind of double-composition polyurethane waterproof paint, described A component comprises: three kinds of polyethers (3050#, 220#, 210#), TDI, softening agent, B component comprises: tenderizer (liquid petroleum resin), inorganic powder (cement, flyash, talcum powder, dicalcium powder, zinc oxide, lime powder), mixed solution (water and nonionogenic tenside), Namigai, its preparation method has comprised the step of preparing performed polymer, and technique is comparatively loaded down with trivial details.
In conjunction with the feature of kitchen guarding's waterproofing work and above-mentioned defect, produce a kind of single-component and have waterproof paint concurrently and the polymer cement-based waterproof material of the excellent properties of waterproof mortar can well solve the deficiency that prior art exists, have no at present report.
Summary of the invention
The object of the present invention is to provide the multi-functional concentrate feed of a kind of kitchen guarding's cement group water-proofing material, utilize this concentrate feed with cement, silica powder mixes by proportioning can be for the preparation of the single-component polymer cement waterproof material of kitchen guarding's waterproof construction, this kind of single polymer cement waterproofing material has excellent water resistance, during construction, only need shallow layer can realize waterproof, also there is good rigidity, be easy to the paving of follow-up ceramic tile, be applicable to the waterproof of meet/back side; This concentrate feed formula can be filled a prescription by regulating respective components content to form winter and summer, transportation, easy to use; Modification waste Crumb rubber in concentrate feed can reduce the density of polymer cement waterproof material, greatly improves the spreading rate of water-proof coating.
