Description
Technical field
The present invention relates to a kind of construction industry and use dry powder paint, specifically be that a kind of anticracking is protected look zero VOC zero accumulation of salt in the surface soil water-based dry powder building colo(u)r coating, belong to building material field.
Background technology
Along with Building Trade in China is flourish, various outer (interior) wall facing materials emerge in an endless stream, and early stage brick facial ornament face occupies nearly 90% the market share; In using, existed many deficiencies afterwards, as: come off, high some place is prone to pound when coming off hurts sb.'s feelings; Be prone to be full of cracks; Construction, maintenance cost height, it is extremely difficult especially to change facing, and the city appearance is persevered for several decades as if it were one day.Countries and regions government had taked relative measures according to the practical situation of each department afterwards, and the emulsion coatings that released one after another (stemming from Japan) is though overcome some above-mentioned deficiency; But many problems also occurred in using, paint film is thin, and anti-cracking is not enough; Be prone to stain, especially elastic coating more is prone to stain, and elasticity and anti-pollution characteristic are difficult to balance; Fugitive color, weathering resistance is relatively poor, also has a certain amount of light pollution; Be difficult to satisfy high-grade facing requirement, in construction and the use VOC gas arranged, influence human health.Given this because of, my research staff of company produces a kind of novel inorganic anticracking and protects look zero VOC zero accumulation of salt in the surface soil water-based dry powder building colo(u)r coating through research and development in a lot of years, satisfies the demand of following Green environmental-protection building.
Summary of the invention
To the deficiency that above-mentioned prior art exists, the purpose of this invention is to provide the water-based dry powder building colo(u)r coating of a kind of anticracking, guarantor's look, zero VOC, zero accumulation of salt in the surface soil.
Be above-mentioned technical problem, the technical scheme that the present invention adopts is:
Anticracking is protected look zero VOC zero accumulation of salt in the surface soil water-based dry powder building colo(u)r coating, is made up of the material of following weight percent:
Low alkali agglutinate 20-40%; Color sand 50-60%; Sepiolite powder 4-9%; Fluidizer 0.01-0.015%; High-strength structureal adhesives 0.05%, redispersable latex powder 3-9%; Hydrophober 0.01%; Antalkaline 0-0.1%; Powdery dispersion agent 0.01-0.02%; Powdery skimmer 0-0.02%; Mineral dye 0.8-2%.
In above-mentioned prescription, low alkali agglutinate is the agglutinate of Ph value between 9-10, and the alkalescence of agglutinate can not be too strong, the tetanic excessively accumulation of salt in the surface soil degree that affects coating that connects of alkalescence.
In above-mentioned prescription, low alkali agglutinate is preferably low alkali aluminosulfate cement.
In above-mentioned prescription, said color sand be natural colored stone ore deposit through ore dressing, pulverize and the mesh sieve that differs in size after the sand of the different meshes that obtains, wherein the different meshes sand is respectively 20 orders, 40 orders, 60 orders.
In above-mentioned prescription, sepiolite powder is that natural one-level sepiolite or secondary sepiolite worn into 300 orders or 200 purpose meals respectively, and wherein each component is by weight in the one-level sepiolite: sepiolite 70%, quartz 10%, talcum 15%, calcite 5%; Each component is sepiolite 27.38%, quartz 18.62%, talcum 9%, calcite 38%, rhombspar 7% by weight in the secondary sepiolite.
In above-mentioned prescription, said high-strength structureal adhesives are preferably etherificate polyvinylpyrrolidine copper tackiness agent.The use of high-strength structureal adhesives can make that coating anti-shrinks, do not chap, not hollowing, non-scale.
In above-mentioned prescription, said redispersable latex powder is preferably propenoate and the styrene copolymerized propenoate redispersable latex powder that forms.It is the film forming base-material of dry powder paint, and its consumption is directly connected to the performance of dry powder paint, and its consumption is crossed the low intensity and the adhesive property that can influence coating, and too high meeting influence degree of drying and increase cost.
The adding of powdery dispersion agent is in order to disperse those to be difficult to be dissolved in the solid particulate of liquid, also to prevent the sedimentation and the cohesion of solid particulate simultaneously, forming stable suspension-s.Dispersion agent uses in dry powder trade sales coating system, and along with the increase of consumption, the slurry viscosity can descend, so must its consumption of control.
The adding of powdery skimmer mainly is to produce bubble in the construction process in order to prevent.
The adding of mineral dye is in order to increase the ornamental of coating, and consumption is 0.8-2%, can require to add color dye according to different decorations.
At the construction field (site), this inorganic powder building colo(u)r coating is added water, the back spraying that stirs gets final product, wherein coating: water=1: 0.15-0.25.
The present invention has the following advantages than prior art:
1, production technique of the present invention is simple; Raw material is prone to purchase; Cheap; Accumulating is convenient, easy (its flow process: characteristics such as the solid moulding mould → batch mixing of basic unit's levelling → horizontal resiliency lattice → subsides (material: water 1: 0.15-0.25) → manual smear or mechanically spraying → remove mould → manual roller coating and mechanically spraying → inferior optical transparency waterproofing protection film) of quick construction;
2, compare with brick facial ornament face that cost is low, lightweight, alleviate built-loading thing, color variation, Artline, no light pollution, environmental protection, easy construction, design random big, be prone to renovation;
3, compare with the emulsion facing, do not have any volatilization pungent, zero VOC, stain resistance is strong; Deposit non-volatilely, accumulating is convenient, color texture nature, and vision is soft; Stereoscopic sensation is strong, and snappiness is strong, anti-shrinks, do not chap, not hollowing, non-scale, less demanding to Base Smoothness, can economize putty layer; Can eliminate trickle unfairness place of elevation of building, production cost is low, environmental protection, reusable edible.
