Description
Technical field
The present invention relates to the technical field of coating, in particular to a kind of water building outer wall coating materials and its system of anti-line of creeping
Preparation Method.
Background technique
China has a vast territory, and with the propulsion of reform and opening-up and modernization construction process, the construction market in China is welcome
New opportunity to develop phase, large quantities of novel construction materials are also applied in the decorations of building.Especially aqueous architectural
Exterior coating is widely used as a kind of environment-friendly materials.Although by the joint efforts in nearly 20 years industries, aqueous architectural
Exterior coating is in application process especially by water (including the water after rainwater, dew, ice dissolution, any Jie in thick fog
Matter) infiltration or after washing away, it is (bright that Water-soluble Organic Substances dissolve out from paint film and be deposited in the strip discoloration that surface of the paint film leaves
Spot, watermark, pollution or calcium spot etc.) similar reptile (such as base eyes, Stylommatophora class reptile) trace for creeping is (following
Referred to as creep line), due to the uneven of line generation that creep, and this phenomenon finally gives coating surface once generating cannot eliminate
The defect for influencing decorative effect is left, water paint further genralrlization application is affected.
The aqueous architectural coating for how developing a kind of anti-line of creeping makes product pass through water (including rain in application process
Any medium in water, thick fog after water, dew, ice dissolution) line and paint film are creeped in infiltration or do not occur after washing away will not
As the variation of environment, weather etc. generates line of creeping, so that it is guaranteed that keeping the dicoration of coating while the performance of product, reach
The purpose for beautifying building, is those skilled in the art's urgently problem to be solved.
In addition, the aqueous architectural coating product category non-dangerous article of anti-line of creeping of the invention, is environmentally friendly machine, product exists
There is no stringent fire protection requirement in production, transport and storage, work progress.
Summary of the invention
The purpose of the present invention is overcoming the above-mentioned prior art, existing aqueous architectural can be overcome by providing one kind
Coating is in application process especially by water (including the water after rainwater, dew, ice dissolution, any medium in thick fog) leaching
Moisten or wash away rear Water-soluble Organic Substances and the dress that the line of creeping that surface of the paint film leaves causes coating is dissolved out and be deposited in from paint film
Decorations property etc. the defect of declines, can to external wall have lasting decorative effect anti-line of creeping water building outer wall coating material
And preparation method thereof.
To achieve the goals above, the water building outer wall coating material of anti-line of creeping of the invention is as follows:
The component of the composition of raw materials of the coating by mass percentage includes:
Water soluble acrylic acid copolymer emulsion 18%~29%, hydroxyethyl cellulose 0.3%~0.6%, inorganic pigment 11.3%
~14.6%, filler 14.2%~22.6%, phosphorus flake graphite alkene 5.2%~6.2%, wetting dispersing agent 0.8%~1.3%,
Multifunctional assistant 0.4%~1.3%, defoaming agent 0.5%~1.2%, fungicide 1.0%~1.8%, thickener 2.2%~
3.4%, coalescing agent 1.8%~2.6%, antifreezing agent 2.2%~2.8%, reverse osmosis antisludging agent 1.0%~1.8% and water
23.3%~29.8%.
Preferably, the solid content of the water soluble acrylic acid copolymer emulsion is 48%~50%.
Preferably, active ingredient >=88% of the hydroxyethyl cellulose, water-insoluble≤0.3%, ash content≤5%,
The viscosity of water content≤6%, salt content≤2%, 0.18mm granule content >=95% below and 2wt% aqueous solution is preferable
Ground≤50000mPas.
Preferably, the filler is one of sericite in powder, kaolin and powdered whiting or a variety of, the pigment
For one of rutile titanium white, iron oxide yellow, iron oxide red or a variety of.
Preferably, the wetting dispersing agent is polycarboxylic acids amine salt wetting dispersing agent, the defoaming agent is poly- methyl silicon
Oxygen alkanes defoaming agent, the fungicide are thiazoline ketone fungicide, and the thickener is the thickening of association type polyurethanes
Agent, the antifreezing agent are propylene glycol and/or ethylene glycol, and the reverse osmosis antisludging agent is without phosphorus to be made of multiple copolymer
Antisludging agent.
Preferably, the pH value of the environmental protection coating material is 8.0~9.0.
Another aspect of the present invention provides a kind of preparation method of the water building outer wall coating material of anti-line of creeping, the system
