Description
Technical field
The present invention relates to a kind of polymer cement waterproof paint, be specifically related to a kind of environmental protection
Type after stain polymer cement waterproof paint.
Background technology
Polymer cement waterproof paint is a kind of with polyacrylate dispersion, ethylene-vinegar
Organic liquid material that the polymer emulsions such as vinyl acetate copolymer emulsion form with various additives, and water
The inorganic powder that the inorganic fillers such as mud, quartz sand, light ground calcium carbonate and various additive are formed
Expect by rational proportion, compounded a kind of double-component, aqueous architectural water-repellent paint.But
Polymer cement waterproof paint typically uses the color of cement, i.e. Lycoperdon polymorphum Vitt or white, is so coated with
The color of material is the most single, it is impossible to meet client's requirement to coating different colours；Or at powder
Material is just colour developing when making.
Such as, prior art CN201110174717.4 discloses a kind of color polymer
Thing cement waterproof paint, is made up of powder and liquid material, and powder includes: inert inorganic powder 1-4
Part, pigment 0.001-0.01 part, the aqueous solution 0.5-1 part containing polymer emulsion 10%-20%,
Cement 1-7 part, dispersant 0.002-0.01 part；Liquid material includes: polymer emulsion 0.5-0.9
Part, water 0.1-0.5 part, defoamer 0.01-0.003 part.This invention overcomes common double group
The color distortion that part coating brings because of proportion scale difference, makes polymer cement waterproof paint colored
Change real realization.But what powder was made is colored powder, and hot strength, extension
Rate relative reduction, simultaneously need to add defoamer.CN201310190741.6 discloses one
Green polymer cement waterproof paint, is made up according to weight proportion stirring of following components: poly-third
Olefin(e) acid ester 110 parts, 65 parts of butadiene-styrene rubber, calcium carbonate 5 parts, lignocellulose 8 parts, stone
5 parts of English powder, cement 65 parts, dispersant 15 parts, defoamer 5 parts, cobalt titanium green pigment 0.05
Part, calcium carbonate 15 parts, film former 4 parts, silane coupler 15 parts.Although face in this invention
Material is uniformly dispersed in coating, elegant in appearance；But green a kind of color can only be realized, it is impossible to
Meet client's requirement to coating different colours, and be also required to add defoamer.
Summary of the invention
The technical problem to be solved is to provide a kind of environment-friendly type, after stain
Polymer cement waterproof paint.
The present invention solves its technical problem and the technical scheme is that a kind of after stain gathers
Compound cement waterproof paint, is made up of component A and B component, wherein, and component A, B component
It is made up of the raw material of following parts by weight respectively,
Component A:
Polymer emulsion 80～85 parts,
Functional aid 1～2 parts,
Water 5～10 parts；
B component:
Further, described polymer emulsion selected from selected from polyacrylate dispersion or/and
Ethylene-vinyl acetate copolymer emulsion, its vitrification point is-15 degree.
Further, described functional aid is selected from waterborne organic silicon emulsion defoamer.
Further, described slow release toner is selected from a kind of particle size range at 20 microns
Hollow structure toner.
Further, described re-dispersible glue powder is selected from acrylate re-dispersible glue powder,
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 of a kind of after stain polymer cement waterproof paint of the present invention
Method, by polymer emulsion, functional aid and water, mix homogeneously, obtains component A；
Slow release toner is pressed and after proportioning toner weighing balance weighs, adds a frequency-conversion agitator by constant
After warm and humid air feed equipment aerating and humidification stirring, put in No. two frequency-conversion agitators, will simultaneously
Re-dispersible glue powder adds stirring and forms additive, the most entirely after weighing with rubber powder metering by proportioning
Portion renders in No. three frequency-conversion agitators, then by white cement and silica flour by proportioning weighing balance
Join mix and blend in No. three frequency-conversion agitators after weighing, obtain B component.Wherein, with three
Platform frequency conversion powder lot dispersing machine laminar is distributed, and the superiors' dispersion machine is provided at a slow speed specific by air-supply pipeline
Humidity air enters dispersion storehouse, is responsible for humidification and the aerating of slow release toner；Middle level dispersion machine is responsible for
The aerating dispersion of re-dispersible glue powder and toner absorption；The mixed of final products be responsible for by bottom dispersion machine
Close dispersion.
After the present invention, coloured polymer cement waterproof paint is by utilizing slow release toner
Surface electrostatic effect and the absorption in advance of re-dispersible glue powder, and by selecting rubber powder size, can
Realize rubber powder at slow release toner surface tight, make toner not represent face in powder state system
Color；In product operational phase, by liquid material and the mixing of powder, emulsion capture rubber powder, color
Powder is discharged in solution, and pre-set color a kind of environment-friendly type without defoamer, rear is showed in exhibition
The polymer cement waterproof paint of color.The present invention is formed as the waterproof painting of specific colour when application
Material, is coated in the surface of cement matrix, along with moisture evaporation and the hydrated cementitious of polymer emulsion
After film forming, form a firm waterproof entirety in interface, can reach impervious waterproof requirement；
May utilize the broken of film self-strength and elastic barrier external environment condition and basic unit's activity gap simultaneously
Bad.
It is demonstrated experimentally that coloured polymer cement waterproof paint extension at break after the present invention
Rate reaches as high as 300%, and hot strength reaches as high as 3.2MPa, and waterproof；Free first
Aldehyde, ammonia, benzene/methylbenzene/dimethylbenzene/ethylbenzene recall rate are zero, and volatile organic matter content is little
In 10g/L, the product with personal color feature can be provided simultaneously.
