The environment-friendly type polymer emulsion building waterproof coating disclosed by the invention is not only excellent in thick coating capability, waterproof effect and anti-cracking effect, but also free of formaldehyde or VOC, and can purify air.
Description
Technical field
The present invention relates to covil construction or other common structures field of waterproof materials.
Background technology
Polymer emulsion building water-proof paint is to take polymer emulsion as main film forming substance, add various surfactants to stablize filling powder and make evaporate into film water-proof paint, after coating volatilization film forming, the softening agent, APE0, various surfactants etc. of existence of the filming material that is harmful to health can slowly be invaded in living environment, causes the long-term hazards to living environment.But this coating does not add the auxiliary materials such as softening agent, tensio-active agent, membrane-forming agent, dispersion agent, and the elastic index of product and stability cannot be protected again.
Summary of the invention
Defect for prior art, the defect of the waterproof paint of especially existing employing photocatalyst, applicant improves system component, by selecting the filler combination of different gradation, physical adsorption, surface oxidation electric charge, realize powder filler self deflocculate, add diatomite and the non-dispersant photocatalyst of high absorbability, the harmful volatile organic compounds of absorption and degraded, obtains environmental protective polymer emulsion building water-proof paint simultaneously.
For achieving the above object, the present invention is achieved through the following technical solutions:
An environmental protective polymer emulsion building water-proof paint, is comprised of polymer emulsion, defoamer, filler, photocatalyst and diatomite.
For the consumption of each composition, can adjust flexibly, be preferably each composition parts by weight: polymer emulsion 80-100 part, defoamer 1-3 part, filler 60-85 part, photocatalyst 5-10 part, diatomite 5-15 part.
Wherein, polymer emulsion is polyacrylate dispersion, ethylene-vinyl acetate copolymer emulsion or the mixture of the two.
Preferably, polymer emulsion is the polymer emulsion that the polyacrylic ester by second-order transition temperature-15 degree forms.
Wherein, defoamer is waterborne organic silicon emulsion defoamer, and preferably its solid content is 60% solid content left and right.
Wherein, photocatalyst is the 0.5-0.8% content photocatalyst of overstepping one's bounds powder system, is preferably photocatalyst of titanium dioxide, and concentration is 0.5%.
Wherein, filler is selected from the mixture of following combination: (kaolin and/or mica powder), (silica powder and/or wollastonite), (superfine titanium white and/or nano silicon micronization).
Above-mentioned combination refers to that the one-tenth limiting from each bracket sub-elects one or both, then the composition of selecting in three groups of brackets is mixed.For example in first bracket combination, select to select to select superfine titanium white in wollastonite, the 3rd bracket combination in kaolin, second bracket combination, then three kinds of compositions are mixed.
Wherein, the specification of each composition is: 350～400 order silica powders, 600～800 order kaolin, 400～600 order wollastonites, 600～800 order mica powders, 10～50nm superfine titanium white, 20～80nm nano silicon micronization.
By aforesaid combination, formed the filler combination of complete different gradation, physical adsorption, surface oxidation electric charge, realize powder filler self deflocculate.
Wherein, diatomite is more than 90 diatomite of 400～500Mu Heng Shi Baidu.
By above-mentioned improvement, the present invention is not using under the prerequisite of various surfactants, by the powder filler of combination different surfaces energy, size distribution, utilize powder self surface electrostatic lotus adsorptivity, and between activation powder surface and emulsion organism, form the adsorptivity of hydrogen bond, all kinds of powders and organism emulsion are formed to stable dispersed, realize powder filler stablizing more than 12 months in emulsion system, no longer add any not volatilizable surfactant material except defoamer simultaneously, its environmental protection index value of detecting is 0, belongs to environment-friendly type coating.
The invention also discloses the preparation method of the said products, comprise the steps: first filler, diatomite to be carried out to premix, standby; Premix filler is fully disperseed and mixed with polymer emulsion, defoamer, finally add photocatalyst to mix.
The invention also discloses the using method of described product, in use product is coated in uniformly to the surface of cement matrix; After moisture evaporation film-forming, in interface, form firm, an elastic waterproof integral body, to reach impervious waterproof and to stop the requirement that the movable gap of basic unit is destroyed; Realize simultaneously and self not discharging and the environment-friendly function of the extraneous harmful organic volatile compounds of absorption degradation.
