Description
Technical field
The present invention relates to a kind of polymer cement waterproof paint, be specifically related to a kind of environment-friendly type after stain polymer cement waterproof paint.
Background technology
Polymer cement waterproof paint is a kind of organic liquid material formed 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 one two component, aqueous architectural waterproof paint.But polymer cement waterproof paint generally adopts the color of cement, i.e. grey or white, the color relation of such coating is very single, can not meet the requirement of client to coating different colours; Or in powder just colour developing when making.
Such as, prior art CN201110174717.4 discloses a kind of colored polymer cement underwater paint, be made up of powder and liquid material, powder comprises: inert inorganic powder 1-4 part, pigment 0.001-0.01 part, containing aqueous solution 0.5-1 part of polymer emulsion 10%-20%, cement 1-7 part, dispersion agent 0.002-0.01 part; Liquid material comprises: polymer emulsion 0.5-0.9 part, water 0.1-0.5 part, defoamer 0.01-0.003 part.This invention overcomes the color distortion that common double component coating brings because of proportion scale difference, and polymer cement waterproof paint colorize is really realized.But what powder was made is colored powder, and tensile strength, unit elongation reduce relatively, need to add defoamer simultaneously.CN201310190741.6 discloses a kind of Green polymer cement waterproof paint, is made up: polyacrylic ester 110 parts, 65 parts, styrene-butadiene rubber(SBR), 5 parts, calcium carbonate, lignocellulose 8 parts, silica powder 5 parts, cement 65 parts, dispersion agent 15 parts, defoamer 5 parts, cobalt titanium phthalocyanine 0.05 part, 15 parts, calcium carbonate, membrane-forming agent 4 parts, silane coupling agent 15 parts of following component according to weight proportion stirring.Although in this invention, pigment is uniformly dispersed in coating, elegant in appearance; But green a kind of color can only be realized, the requirement of client to coating different colours can not be met, and also need to add defoamer.
Summary of the invention
Technical problem to be solved by this invention is, provides the polymer cement waterproof paint of a kind of environment-friendly type, after stain.
The technical scheme that the present invention solves the employing of its technical problem is: a kind of after stain polymer cement waterproof paint, is made up of component A and B component, and wherein, component A, B component are made up of the raw material of following parts by weight respectively,
Component A:
Polymer emulsion 80 ~ 85 parts,
Functional aid 1 ~ 2 part,
5 ~ 10 parts, water;
B component:
Further, described polymer emulsion is selected from polyacrylate dispersion or/and ethylene-vinyl acetate copolymer emulsion, and its second-order transition temperature is-15 degree.
Further, described functional aid is selected from waterborne organic silicon emulsion defoamer.
Further, described slowly-releasing toner is selected from the hollow structure toner of a kind of particle size range at 20 microns.
Further, described re-dispersible glue powder is selected from acrylate re-dispersible glue powder, and its particle size range is at 0.2 ~ 0.5 micron.
Further, described cement is selected from 32.5 white portland cements.
During application, component A and B component stir according to 1: 1 ~ 1.5 ratios, can use.
Preferably, the preparation method of a kind of after stain polymer cement waterproof paint of the present invention, by polymer emulsion, functional aid and water, mixes, obtains component A; A frequency-conversion agitator is added by after constant warm and humid air feed equipment aerating and humidification stirring after being weighed by proportioning toner weighing balance by slowly-releasing toner, put in No. two frequency-conversion agitators, add to stir after re-dispersible glue powder being weighed by the metering of proportioning rubber powder simultaneously and form addition material, all render in No. three frequency-conversion agitators afterwards, then join mix and blend in No. three frequency-conversion agitators after white cement and silica powder being weighed by proportioning weighing balance, obtain B component.Wherein, with three frequency conversion powder lot dispersing machine laminar distributions, the superiors' dispersion machine provides at a slow speed specified moisture air to enter dispersion storehouse by air-supply pipeline, is responsible for humidification and the aerating of slowly-releasing toner; Middle level dispersion machine is responsible for aerating dispersion and the toner absorption of re-dispersible glue powder; The blending dispersion of the finished product is responsible for by bottom dispersion machine.
After the present invention, coloured polymer cement waterproof paint is by utilizing the absorption in advance of slowly-releasing toner surface electrostatic interaction and re-dispersible glue powder, and by selecting rubber powder size, rubber powder can be realized closely wrap up at slowly-releasing toner surface, make toner not represent color in powder state system; In product operational phase, by the mixing of liquid material and powder, capture rubber powder by emulsion, toner is discharged in solution, and a kind of not containing the environment-friendly type of defoamer, the polymer cement waterproof paint of after stain of pre-set color is showed in exhibition.The present invention is formed as the waterproof paint of specific colour when applying, and is coated in the surface of cement matrix, after the moisture evaporation of polymer emulsion and hydrated cementitious film forming, forms a firmly waterproof entirety, can reach impervious waterproof requirement in interface; The destruction in the movable gap of film self-strength and elastic barrier outside atmosphere and basic unit can be utilized simultaneously.
Experiment proves, after the present invention, coloured polymer cement waterproof paint elongation at break reaches as high as 300%, and tensile strength reaches as high as 3.2MPa, and waterproof; Free formaldehyde, ammonia, benzene/methylbenzene/dimethylbenzene/ethylbenzene recall rate are zero, and volatile organic matter content is less than 10g/L, can provide the product with personal color feature simultaneously.
