Abstract

The invention discloses a flat varnish for waterborne wood, comprising the following components in parts by weight: 30-70 percent of waterborne acrylic emulsion, 0-30 percent of waterborne aliphatic polyurethane and mixture emulsion, 3-10 percent of film forming aid, 0.01-2 percent of antifoaming agent, 0.01-2 percent of dispersing agent, 0.1-5 percent of extinction powder, 0-2 percent of wetting agent, 0.01-2 percent of rheological additive, 0.01-2 percent of wax additive, 0.01-2 percent of hand-feeling addictive, 0.01-2 percent of thickening agent, 0.01-2 percent of ammonia water, 0.01-2 percent of coupling agent and 5-30 percent of water. The flat varnish for waterborne wood has the advantage of ensuring that a varnish film has better fullness, hardness, high chemical resistance, super-strong hand feeling and strong adhesive force on an oil primer. In addition, the flat varnish for waterborne wood can solve the compatibility between the aquosity and the oilness, ensure the varnish film cannot fall off after being dried and can meet the requirement for consumers on high environmental protection, low odor and less pollution.

Description

A kind of water-based woodenware matte varnish
Technical field
The present invention relates to a kind of coating of chemical field, particularly relate to the protective cover that is applied to industrial wood furniture surface.
Background technology
The woodwork coating that present China uses is solvent-borne type mostly, and these woodwork coatings all contain a large amount of organic volatile compounds (VOC), and serious harm producers and workmen's is healthy.The enhancing of Along with people's environmental consciousness, conventional solvent type coating faces a severe challenge, advantage such as that water-borne coatings has is nontoxic, nonflammable, nonpollution environment.Water-borne coatings combines the high performance of solvent based coating with the low VOC content of water-borne coatings, environmental effect is good, construction is convenient relatively.But China's water-borne coatings is in the technology starting stage at present, and film performance does not often reach human consumer's requirement, has defectives such as being prone to subside, filling inadequately, fullness ratio is not enough, hardness is not strong.
Summary of the invention
To above-mentioned technological deficiency, the technical problem that the present invention will solve is to improve the sticking power of water-based woodenware matte varnish on oil primer, need solve the difficult compatible technological difficulties of water oil simultaneously.Even use the outstanding ACRYLIC EMULSION of sticking power as main film forming substance; But the ply adhesion only according to emulsion is far from being enough; Other auxiliary agents of also need arranging in pairs or groups improve the sticking power between water oil, also need solve the consistency between water-based and oiliness by hydrophilic and lipophilic film coalescence aid simultaneously.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of water-based woodenware matte varnish, by weight: aqueous acrylic emulsion 30-70%, water-based aliphatic polyurethane and mixture emulsion 0-30%, film coalescence aid 3-10%, skimmer 0.01-2%, dispersion agent 0.01-2%, flatting silica 0.1-5%, wetting agent 0-2%, auxiliary rheological agents 0.01-2%, wax assistant 0.01-2%, feel auxiliary agent 0.01-2%, thickening material 0.01-2%, ammoniacal liquor 0.01-2%, coupling agent 0.01-2%, water 5-30%.
Further: in above-mentioned water-based woodenware matte varnish, described aqueous acrylic emulsion and aqueous polyurethane emulsion are a kind of filmogens of key.Said film coalescence aid is one or more of the pure ether solvent used always of those skilled in the art.Described skimmer is mineral oil defoaming agent, silicone based skimmer, the type siloxane skimmer that those skilled in the art use always.Described dispersion agent is nonionogenic tenside, ROHM amine salt.Described flatting silica is the silicon-dioxide flatting silica.Described wetting agent is a siloxane type surfactants.Described auxiliary rheological agents is polyurethane-modified rheological agent.Described wax assistant is one or both in polyethylene wax, the amide waxe.Described feel auxiliary agent is organosilicon surface auxiliary agent, scratch resistance auxiliary agent, the slip(ping)agent that those skilled in the art use always.Described thickening material is one or more in polyacrylic thickening material, polyurethanes thickening material, the associative thickener.Described ammoniacal liquor is high purity ammoniacal liquor.Said coupling agent is a silane coupling agent.Described water is a kind of in pure water, zero(ppm) water, the deionized water.
The system lacquer method of using always according to those skilled in the art; Aqueous acrylic emulsion and aqueous polyurethane emulsion are put into system lacquer container by formula rate; Add entry and film coalescence aid, dispersion agent, skimmer, wax assistant, auxiliary rheological agents and flatting silica while stirring; Add feel auxiliary agent, thickening material, wetting agent and ammoniacal liquor after high speed dispersion to fineness is qualified more while stirring, promptly get this water-based woodenware matte varnish after mixing.
Compared with prior art, the prescription of above-mentioned water-based woodenware matte varnish is aqueous acrylic emulsion 30-70%, aqueous polyurethane and mixture emulsion 0-30%, film coalescence aid 3-10%, skimmer 0.01-2%, dispersion agent 0.01-2%, flatting silica 0.1-5%, wetting agent 0-2%, auxiliary rheological agents 0.01-2%, wax assistant 0.01-2%, feel auxiliary agent 0.01-2%, thickening material 0.01-2%, ammoniacal liquor 0.01-2%, water 5-30%.Select ACRYLIC EMULSION and polyaminoester emulsion to mix and use, make paint film have better fullness ratio, hardness, high chemical resistance.Product has used wax assistant and feel auxiliary agent, makes product have superpower feel.The ACRYLIC EMULSION that this prescription is at first selected to have excellent adhesive attraction is as main film forming substance, and the polyaminoester emulsion of arranging in pairs or groups again strengthens the consistency of aqueous finish paint and oil primer, can not only give the paint film outstanding adhesion; And can solve the compatibility problem between water-based and oiliness, and guarantee can not come off behind the drying varniss, secondly be the selection of film coalescence aid; Must select hydrophilic film coalescence aid and the combination of oil loving film coalescence aid, thoroughly solve the compatible problem between water-based and oiliness, give a complete smooth paint film simultaneously; Make that through coupling agent self-crosslinking intensity increases greatly between emulsion particle at last; Solve water-based paint film and the intermembranous problem of not adhering to of oil-base paint, the smell of high-performance oil primer is coated under the environmental protection finish paint of low smell, and what this construction technology was produced films; Can reach the high-performance of oil paint; Can satisfy the high environmental protection of human consumer again, low smell, oligosaprobic environmental requirement.
