Description
Technical field
The present invention relates to a kind of construction industry 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, early stage brick facial ornament face occupies nearly 90% the market share, in using, existed many deficiencies afterwards, as: come off, when high some place comes off, easily pound and hurt sb.'s feelings, easily be full of cracks, construction, maintenance cost is high, changes facing extremely difficult especially, and city appearance is persevered for several decades as if it were one day.Countries and regions government had taked corresponding measure according to the practical situation of each department afterwards, emulsion coatings (stemming from Japan) has released one after another, although overcome some above-mentioned deficiency, but many problems have also been there is in using, paint film is thin, anti-cracking is not enough, easily stain, especially elastic coating more easily stains, and elasticity and anti-pollution characteristic are difficult to balance, fugitive color, weathering resistance is poor, also has a certain amount of light pollution, is difficult to meet high-grade facing requirement, in construction and use, there is VOC gas, affect human health.Given this research staff of Yin，Wo company, through research and development in a lot of years, 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, meets the demand of following Green environmental-protection building.
Summary of the invention
The deficiency existing for above-mentioned prior art, the water-based dry powder that the object of this invention is to provide a kind of anticracking, guarantor's look, zero VOC, zero accumulation of salt in the surface soil is built colo(u)r coating.
For above-mentioned technical problem, the technical solution used in the present invention is:
Anticracking is protected look zero VOC zero accumulation of salt in the surface soil water-based dry powder building colo(u)r coating, the material of following weight percent, consists of:
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 defoamer 0-0.02%; Mineral dye 0.8-2%.
In above-mentioned formula, low alkali agglutinate is the agglutinate of pH value between 9-10, and the alkalescence of agglutinate can not be too strong, the excessively tetanic accumulation of salt in the surface soil degree that affects coating that connects of alkalescence.
In above-mentioned formula, low alkali agglutinate is preferably low alkali aluminosulfate cement.
In above-mentioned formula, described color sand is natural colored stone ore deposit through ore dressing, the mesh sieve mistake pulverizing and differ in size
The sand of the different meshes obtaining after sieve, wherein different meshes sand is respectively 20 orders, 40 orders, 60 orders.
In above-mentioned formula, sepiolite powder is that natural one-level sepiolite or secondary sepiolite worn into respectively 300 orders or 200 object meals, and wherein in one-level sepiolite, each component is by weight: sepiolite 70%, quartz 10%, talcum 15%, calcite 5%; In secondary sepiolite, each component is sepiolite 27.38%, quartz 18.62%, talcum 9%, calcite 38%, rhombspar 7% by weight.
In above-mentioned formula, described high-strength structureal adhesives are preferably etherificate polyvinylpyrrolidone tackiness agent.The use of high-strength structureal adhesives can make the anti-contraction of coating, not chap, not hollowing, non-scale.
In above-mentioned formula, described redispersable latex powder is preferably acrylate and the styrene copolymerized acrylate redispersable latex powder forming.It is the film forming base-material of dry powder paint, and its consumption is directly connected to the performance of dry powder paint, too low intensity and the adhesive property that can affect coating of its consumption, and too high meeting affect degree of drying and increase cost.
Adding of powdery dispersion agent is in order to disperse those to be difficult to, to be dissolved in the solid particulate of liquid, also prevents sedimentation and the cohesion of solid particulate simultaneously, forms stable suspension.Dispersion agent is used in Dry Powder Architectural Paint system, and along with the increase of consumption, slurry viscosity can decline, so must control its consumption.
Adding of powdery defoamer is mainly in construction process, to produce bubble in order to prevent.
Adding of mineral dye is that consumption is 0.8-2% in order to increase the ornamental of coating, can require to add according to different decorations the pigment of different colours.
At the construction field (site), this inorganic powder building colo(u)r coating is added to water, spraying, wherein coating after stirring: water=1: 0.15-0.25.
The present invention, than prior art, has the following advantages:
1, production technique of the present invention is simple, raw material is easily purchased, cheap, accumulating is convenient, easy (its flow process: the features 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 → sub-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, without light pollution, environmental protection, easy construction, design randomness greatly, easily renovation;
3, compare with emulsion facing, without any volatilization pungent, zero VOC, stain resistance is strong, deposits non-volatilely, and accumulating is convenient, color texture nature, vision is soft, and stereoscopic sensation is strong, strong, the anti-contraction of snappiness, 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.
