Summary of the invention
At above-mentioned technological deficiency, the technical problem to be solved in the present invention is to improve the sticking power of water-based woodenware matte varnish on oil primer, needs to 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 that also need to arrange in pairs or groups improve sticking power between water oil, also need solve 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 solution adopted in the present invention 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%, defoamer 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.Described film coalescence aid is one or more of the pure ether solvent used always of those skilled in the art.Described defoamer is mineral oil defoaming agent, silicone based defoamer, the type siloxane defoamer that those skilled in the art use always.Described dispersion agent is nonionogenic tenside, polyacrylic acid 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.Described coupling agent is a silane coupling agent.Described water is a kind of in pure water, distilled 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, defoamer, wax assistant, auxiliary rheological agents and flatting silica while stirring, high speed dispersion adds feel auxiliary agent, thickening material, wetting agent and ammoniacal liquor to fineness after qualified more while stirring, promptly gets 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%, defoamer 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.This prescription at first selects to have the ACRYLIC EMULSION of excellent adhesive attraction as main film forming substance, 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 sticking power of paint film excellence, and can solve compatibility problem between water-based and oiliness, guarantee can not come off behind the drying varniss, next is 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 by 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, what this construction technology was produced films, and can reach the high-performance of oil paint, can satisfy the high environmental protection of human consumer again, low smell, oligosaprobic environmental requirement.
