The acrylic modified polyurethane emulsion is formed by copolymerizing acrylics monomers, acrylic acid and waterborne polyurethane dispersoid, and the solid mass percentage is 30-40%. The scratch resistance water-borne wood coating has the advantages that water is used as a solvent, the coating is environment-friendly and energy-saving and good in dryness and anti-adhesion; the coating is good in scratch resistance and firm in film; and construction is simple, maintenance is easy, and recoatability is good.
Description
Technical field
The present invention relates to a kind of water-borne wood coating.
Technical background
In woodwork coating market, water-borne wood coating had appearred in the last few years, and water-borne wood coating is owing to being solvent with water, and environmental protection, little to the HUMAN HEALTH influence obtains application more and more widely in the wooden furniture of family is decorated.Water-borne wood coating has sticking power, water tolerance, chemical resistance and easy construction preferably in the coating that wooden article surface forms, and can substitute high, the harmful solvent borne polyurethane woodwork coating of VOC content.But in the actual use of water-borne wood coating; Because technology and raw-material problem; General water-borne wood coating be not very desirable aspect raw-material selection and the optimization of formulation, and the scratch resistance performance of coatingsurface is relatively poor, very easily lets external object that its film coated surface is scratched; Cause the destruction of coating decoration and provide protection, influenced the application of water-borne wood coating in furniture is decorated.
Summary of the invention
Technical problem to be solved by this invention provides a kind of scratch resistance water-borne wood coating, and it has excellent scratch resistance performance in the coating that the case goods surface forms.For this reason, the present invention adopts following technical scheme: it is made up of following mass percent component:
(1) the acrylic acid modified polyurethane emulsion 80.0～86.0%;
(2) film coalescence aid 3.0～5.0%;
(3) skimmer 0.3～0.5%;
(4) deionized water 3.0～11.0%;
(5) wetting agent 0.1～0.3%;
(6) mass percent 48～52% aralkyl modified are gathered methyl alkyl silicon solution 0.1～0.3%;
(7) the wax emulsion 3.0～5.0%;
(8) thickening material 0.3～0.5%;
(9) sanitas 0.1～0.2%;
Said acrylic acid modified polyurethane emulsion is by acrylic ester monomer, vinylformic acid aqueous pu dispersions to be carried out copolymerization to form, and its solid masses per-cent is 30%～40%.
Said film coalescence aid can be selected from dipropylene glycol butyl ether, dipropylene glycol methyl ether, butyl glycol ether.
Said wax emulsion can adopt AQUACER539 water-based wax dispenser.AQUACER539 water-based wax dispenser is the commercial trade mark of product, is German Bi Ke company (BYK-Chemie) product, and Shanghai turtle power chemical industry trade Co., Ltd is on sale, and its non-volatile part of content is 35～37%.
Said skimmer is that water-based system is used silicone antifoam agent, like the BYK024 of German Bi Ke company, BYK028 etc.
Said wetting agent is for containing organosilyl surperficial auxiliary agent, and it can reduce the surface tension of water-based system strongly, increases moistening to ground, like the BYK341 of German Bi Ke company, the H140 of Shenzhen Hai Chuan science and technology etc.
Mass percent 48～52% aralkyl modified are gathered smooth property, resistance to blocking and the scrath resistance ability that methyl alkyl silicon solution can obviously improve coating surface.Said aralkyl modified is gathered the solvent in the methyl alkyl silicon solution, for being dissolvable in water water or in water, being emulsified state and having volatile organic solvent, such as: ethylene glycol monobutyl ether, 1-Methoxy-2-propyl acetate etc.
Said thickening material is a water-based polyurethane rheology thickening material, like this Rheocate278, Rheocate288 etc. of U.S.'s hamming.
Said sanitas is industrial novel environment friendly anticorrosion and bactericidal agent, the PT-2 that produces like Zhejiang Chemical Industry Science and Technology Group Co.,Ltd, PT-3, PN etc.
Owing to adopt technical scheme of the present invention, the present invention is through a kind of water-borne wood coating of rational component collocation preparation, and it has the following advantages: (1): with water is solvent, environmental protection and energy saving; (2): dryness is good, resistance to blocking is excellent; (3): through the scratch resistance factor (50% aralkyl modified is gathered methyl alkyl silicon solution) with the wax emulsion is reasonably combined, the coating resistance to marring is excellent, paint film is hard; (4): easy construction, maintenance is simple and easy, recoatability good.
Embodiment
Configuration technology of the present invention:
With acrylic acid modified polyurethane emulsion input system lacquer cylinder, said acrylic acid modified polyurethane emulsion is by acrylic ester monomer, vinylformic acid aqueous pu dispersions to be carried out copolymerization to form earlier, and its solid masses per-cent is 30%～40%.
Under whipped state, add skimmer; To be pre-mixed uniform film coalescence aid, wetting agent and mass percent 48～52% aralkyl modified gathers methyl alkyl silicon solution and adds at a slow speed in the lacquer cylinder again; High speed dispersion (such as, 2500rpm/min) up to not having the oily phenomenon that contracts at fineness plate upper scraping plate.Drop into wax emulsion, thickening material, sanitas then successively, stir, adjust viscosity, qualified after-filtration, packing with deionized water.
