Abstract
The invention discloses a polymer cement waterproof coating. The coating comprises a liquid ingredient and a powder ingredient. The liquid ingredient comprises a polymer emulsion, triethanolamine, a dispersant, an antiseptic, an antifoaming agent and the balance water. The powder ingredient comprises special cement, ultrafine slag, ultrafine steel slag, metakaolin, an antifoaming agent, water-soluble cellulose, acrylamide powder, bisacrylamide powder, instant sodium silicate, aluminum stearate and the balance heavy calcium carbonate of 400 meshes. The coating has excellent anti-sagging and anti-cracking performances, has a self-repair function, can form crystals in concrete and has a certain secondary anti-permeability.
Description
Technical field
The present invention relates to technical field of chemical paint, be specifically related to a kind of polymer cement waterproof paint.
Background technology
Polymer cement waterproof paint, also known as JS composite water-proof paint, be a kind of organic liquid material formed with polyacrylate dispersion and various additive, and the inorganic powder that the mineral filler such as light water-ground limestone and various additive form is by rational proportion, compounded one two component, aqueous architectural waterproof paint.
Polymer cement waterproof paint is green material, and it is free from environmental pollution, stable performance, ageing resistance is excellent, the waterproof life-span is long; Use safety, easy construction, simple to operate, directly can construct at the moisture substrate without open fire; Cohesive force is strong, and material and cement basal plane cohesive strength can reach more than 0.5MPa, have good adhesive property to most of material; Elastic properties of materials is good, unit elongation can reach 200%; Application property is good, non-foaming, and film-formation result is good, quick solidifying; Construction is simple, brushing, roller coating, scrapes and smears construction.
But along with real estate housing quality uneven, easily there is crack in the places such as kitchen, toilet, vault, produce infiltration phenomenon.Although existing JS waterproof paint has certain unit elongation on market, film coated surface easily produces the defect such as fine crack, pin hole, thus cannot play effect of waterproof, finally causes waterproofing work to lose efficacy.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide one can keep high-elongation for a long time, the polymer cement waterproof paint of high tensile, high bond strength.
Polymer cement waterproof paint provided by the invention, comprises liquid material component and powder component,
By weight percentage, described liquid material component comprises:
Surplus is water;
By weight percentage, described powder component comprises:
Surplus is 400 order water-ground limestones;
Described liquid material component and powder component are 1:0.8 ~ 1.2 according to the blending ratio of weighing scale.
Wherein, described special cement is 42.5 ordinary Portland cements.
Wherein, described macromolecule emulsion is acrylic ester emulsion and ethene-vinyl acetate copolymer emulsion, and both ratios are 6:1-4.
Wherein, described ultra-fine slag and superfine steel slag, fineness is 400-600 order.
Wherein, described water reducer is polycarboxylate water-reducer and melamine high-efficiency water-reducing agent.
Wherein, described water soluble cellulose is at least one or several in methylcellulose gum, Vltra tears, Natvosol, carboxymethyl cellulose, and its viscosity is greater than 50000mpas.
The present invention by adding the resin of different ratios in liquid material; film is made to form fine and close crossover network; utilize acrylamide simultaneously under the effect of the catalyzer such as trolamine, form one deck in film coated surface and there is elasticity, and acid and alkali-resistance; the protective layer of resistance to bubble; and water glass in powder and sodium stearate soluble in water, under the effect of capillary force, go deep into crack, with the alkali substance reaction in cement; generate the xln of insoluble in water, stop the infiltration of moisture.So by the protection of outer protective layer and the formation of bottom crystal body, make polymer cement waterproof paint not by the destruction of extraneous factor, high-elongation can be kept for a long time, high tensile, high bond strength.
Due to the employing of technique scheme, compared with prior art, tool of the present invention has the following advantages:
1, the polymer cement waterproof paint for preparing of the present invention, its indices all meets standard GB/T/T23445-2009, has good performance advantage.
2, the polymer cement waterproof paint for preparing of the present invention, has excellent thick painting and resistance to cleavage.
3, the polymer cement waterproof paint for preparing of the present invention, unit elongation is large, cohesive strength is high, water-alkali resistance good weatherability, directly can construct at the basal plane without open fire, be widely used in the waterproof of the less basic unit of the activities such as kitchen, toilet, balcony, vault.
4, the polymer cement waterproof paint for preparing of the present invention; by the protection of outer protective layer and the formation of bottom crystal body; make polymer cement waterproof paint not by the destruction of extraneous factor, high-elongation can be kept for a long time, high tensile, high bond strength.
5, preparation method's technique of the present invention is simple, easy handling, and cost is low, is easy to promote.
