Description

A kind of Water-based crack sandstone paint and preparation method thereof
Technical field
The present invention relates to the building coating technical field, be specifically related to a kind of Water-based crack sandstone paint and preparation method thereof.
Background technology
Coating is called paint in Chinese tradition, be a kind ofly can be coated in different construction technologies article surface, form to adhere to firmly, have some strength, continuous solid film.The effect of traditional coating mainly contains 3 points: the defective of protecting, decorate and cover up product.Along with the development of industry and the raising of people's user demand, people are more and more higher to the requirement of the decoration functions of coating.Crackle coating arises at the historic moment thus.
Crackle coating, namely be to be coated with to examine behind surface of wall to crack shape, have graceful aesthetic feeling, belong to the coating of fine arts type, special because of its outward appearance, have fine arts impression and be widely used in the home decoration, especially be applied in the medium-to-high grade decoration technology engineering.Although the water-based crackle coating product on the market is more and more gradually now, most crackle material products are the single layer coating lacquer, and the product effect rests on the basis of colour contrast and produces crazing effect as main, and the stereo concave-convex sense is not strong.In addition, most water-borne coatings lacquers also exist following problem: the first, and need in 2-4 hour, be finished after coating is enabled, otherwise can go bad; The second, the crackle effect is inhomogeneous, and some one-tenth bulks do not ftracture, and some crackings are excessive; The 3rd, it is poor that paint vehicle solidifies rear stability at substrate surface, easily peels off, and is not durable.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of Water-based crack sandstone paint is provided, this coating can crack sandstone after applying, and stereoscopic sensation is strong, good decorating effect and durable.
For achieving the above object, the present invention adopts following technical scheme:
A kind of Water-based crack sandstone paint is comprised of ground coating composition and face coating combination, and described ground coating composition is composed of the following components by weight percentage:
Described coating combination is composed of the following components by weight percentage:
Preferably, described water soluble resin is arab resin, and described elastic emulsion is acrylate and Organosiliconcopolymere.
During construction, use first the wool cylinder at metope roller coating one deck alkali resistant priming paint, stop alkaline attack, after alkali resistant priming paint parches, again with the wool cylinder with the ground coating composition roller coating to the metope of handling well.This is because the penetrating power of crackle sandstone ground coating composition is stronger, guarantees first before the coating that ground coating composition does not permeate body of wall inside, thereby ground coating composition and face coating combination can be reacted effectively, guarantees to ftracture preferably effect.Last coated side coating combination again, 3min can see segmentation crack and sandstone shape after finishing.
The mechanism that the present invention cracks is: the ground coating composition among the present invention is the elastic material with strong viscosity, and the acrylic resin in the face coating combination dissolves arab resin with after arab resin, elastic emulsion in the ground coating composition contacts once again.Ground coating composition with interpenetrate after the face coating combination contacts, form by force absorption.And the face coating combination applies one and can rapid drying solidify in air, produces in the process of solidifying and shrinks, and under the viscous effect of ground coating composition, finishing coat has produced and shunk inhomogeneous and ftracture into irregular crackle.
Preferably, the subsidiary material of ground coating composition comprise dispersion agent, wetting agent, biocide mildewcide, film coalescence aid, ethylene glycol, caustic solubility thickening material, deionized water, by mass percentage dispersion agent 0.5-2%, wetting agent 1.5-3%, biocide mildewcide 0.5-1%, film coalescence aid 1-3.5%, ethylene glycol 1-1.5%, caustic solubility thickening material 1.5-2.5%, deionized water 10-13%.
Preferably, the film coalescence aid of described ground coating composition is peroxidation (2 ethyl hexanoic acid) tert-butyl ester.
Preferably, subsidiary material in described coating combination comprise film coalescence aid, ethylene glycol, dispersion agent, defoamer, biocide mildewcide, deionized water, by mass percentage film coalescence aid 1-1.5%, ethylene glycol 0.7-1%, dispersion agent 0.5-1%, defoamer 0.5-1%, biocide mildewcide 0.3-1.5%, deionized water 5-7%.
Preferably, the film coalescence aid of described coating combination is peroxidation (2 ethyl hexanoic acid) tert-butyl ester.
Another object of the present invention is to provide a kind of preparation method of Water-based crack sandstone paint, the method may further comprise the steps:
1) preparation of ground coating composition: under the condition of high speed dispersion, drop into water soluble resin, nano-calcium carbonate calcium powder, titanium dioxide in the deionized water above-mentioned three kinds of materials are dissolved fully, then under the middling speed dispersion condition, add elastic emulsion, Natvosol, subsidiary material;
2) preparation of face coating combination: deionized water is added in the container, under the condition that middling speed stirs, add first subsidiary material, under the condition that continues after the subsidiary material dissolving in stirring at low speed, add acrylic resin, quartz sand, nano-calcium carbonate calcium powder, titanium dioxide, elastic emulsion, Natvosol.
Preferably, step 1) and step 2) in, the rotating speed of high speed dispersion is 1001-1500r/min, and the rotating speed that middling speed is disperseed is 600-1000r/min, and the rotating speed of stirring at low speed is 50-100r/min.
Preferably, during the preparation of ground coating composition, high speed dispersion 10-20min behind adding water soluble resin, nano-calcium carbonate calcium powder and the titanium dioxide.
Preferably, during the preparation of face coating combination, stirring at low speed 10-15min after the subsidiary material adding is gone in the dried up sub-water, stirring at low speed 5-10min after acrylic resin, quartz sand, nano-calcium carbonate calcium powder, titanium dioxide, elastic emulsion, Natvosol add.
Compared with prior art, the invention has the beneficial effects as follows:
1. coating of the present invention is liquid, need not during use to be dissolved in water in addition or to dilute, and can use immediately after uncapping;
2. paint stability of the present invention is good, and is after the use of uncapping, reusable after residue coating hermetically drying is preserved;
3. the crackle that produces after coating of the present invention applies is even, and irregular crackle thickness is in the scope of 0.1-0.2mm, and invariably ftractureing or ftractureing phenomenon inhomogeneous produces;
4. be that visible crackle produces about 3min after coating of the present invention applies, need not additionally to provide heat energy dry, convenient to use;
5. between the two-layer lacquer physical action occurs after coating of the present invention applies, viscosity and the adsorptive power of primary coat are strong, and being attached to well on the base material also well, adsorption plane is coated with material, waterproof, durable, anti-scrubbing.
