Abstract
The invention provides polishing-free polyurethane primer. The polishing-free polyurethane primer comprises the following components in parts by weight: 50 to 80 parts of short-oil alkyd resins, 5 to 15 parts of solvent, and 15 to 25 parts of filler, wherein the filler is of 3000 meshes in fineness. The polishing-free polyurethane primer adopts the short-oil alkyd resins which are high in sinking resistance, so that the sinking resistance of the grinding-free polyurethane primer can be improved; the smoothness of the surface of the polishing-free polyurethane primer is improved because of the fineness of the surface of the superfine filler, and therefore, the process of polishing can be saved, and as a result, the efficiency and benefit of a furniture plant can be increased.
Description
Technical field
The present invention relates to a kind of priming paint, relate in particular to a kind of exempt to polish polyurethane primer and main lacquer thereof.
Background technology
Human being's production and make the history of painting to pass up to the Stone Age.Confirm from a large amount of archaeological materials of having found, the primitive society before apart from modern 7000, the original covering with paint materials of preparation such as human grease, myron and the natural pigment that has just used wild beast are painted with feather, branch etc., to reach the purpose of decoration.Along with the progress of human society, after entering the Bronze Age, there is different progress ancient civilized country at that time aspect the crude substance preparation coating directly utilizing.Lacquer decorative device and palace, temple just take off from wild lacquer tree as far back as the Shang dynasty in China.Just grasped the technology of tempering tung oil coating processed to the The Spring and Autumn Period, can use raw lacquer and the composite coating of tung oil the period of the Warring States, started the technology that makes used additives in coating, promotion paint development to a New Times.The lacquer coffin that is unearthed from the Changsha Han tomb at Mawangdui and the paint film of lacquerware are tough and tensile, and protective value is excellent, proves absolutely in B.C. 2nd century maturity that China uses the development of raw lacquer technology to reach.Enter eighties of last century, succeeding in developing of the significant achievement of polymer science theory and various macromolecular compounds put into production, for the paint development has been started the New Times.Succeeded in developing the special Synolac that is used as the filmogen of coating the twenties in last century, from then on various synthetic resins newly developed are applied in coating very soon, and coating was entered take synthetic filmogen as the main epoch.
In the modern furniture production, general coating is brushed and is difficult to smoothly, beats what a smooth basal plane so will polish for the brushing effect of back.The aesthetic property of furniture surface depends on the quality of the quality of polishing to a great extent.As everyone knows, now in the furniture production process, no matter be solid wood enterprise or plate fitment enterprise, workload and number at most, the most concentrated be exactly between grinding machine, going wrong maximum also is between grinding machine, polishing workshop section then is labor intensive, the workshop section that efficient is the lowest, general one sprays the workman, needs the polishing workman of about 4 of collocation, complex part even higher, say that tactics of human sea was not yet.Because singularity and the otherness of material itself, and the opposite sex that are wanting in such as the component shape after the processing and moulding are also very large, add limited machining functions and the cost consideration of sanding apparatus, also do not have to replace fully well at present the way of manual sanding.And Furniture Manufacturing Enterprise has badly influenced the profit of Furniture Manufacturing Enterprise because personnel cost rises, improved efficiency is difficult in recent years.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of polyurethane primer of polishing of exempting from is provided, save polishing to promote efficient and the profit of furniture producer.
The invention provides a kind of the main of polyurethane primer of exempting to polish and coat with lacquer, according to the parts by weight meter, comprising:
Short-oil alkyd 50 ~ 80 weight parts;
Solvent 5 ~ 15 weight parts;
Filler 15 ~ 25 weight parts;
Wherein, the filler fineness surpasses 3000 orders.
Wherein, described solvent can be one or more the mixture in esters solvent, aromatic hydrocarbon solvent, pure ether solvent, ketones solvent or the alcoholic solvent etc.Esters solvent can be butylacetate, ethyl acetate, methylcarbonate or 1-Methoxy-2-propyl acetate etc.; Aromatic hydrocarbon solvent can be toluene, dimethylbenzene, trimethylbenzene or durene etc.; The alcohol ether solvent can be glycol propyl ether, butyl glycol ether or propylene glycol propyl ether etc.; Ketones solvent can be pimelinketone or methylethylketone etc.; Alcoholic solvent can be Virahol, propyl carbinol or hexalin etc.
Preferably, described solvent is selected from least a in N-BUTYL ACETATE and the 1-Methoxy-2-propyl acetate etc.
Wherein, filler can be selected from least a in calcium carbonate, talcum powder, transparent powder, pure aluminium silicate, calcium sulfate, barium sulfate, silicon-dioxide, mica and the Calucium Silicate powder etc.
Preferably, described filler component contains talcum powder and transparent powder.
Preferably, described talcum powder is the cosmetic-grade talc powder.
Transparent powder is a kind of non-metallic minerals, and transparency is high, and whiteness is good, refraction 1.54, and density 2.3, oil suction 25, nonpoisonous and tasteless, acidproof durable corrosion, the transparency is high.The refractive index of transparent powder itself and the refractive index of most synthetic resins are very approaching, so the amount of filling out of transparent powder does not affect the transparency of finished product; Can improve surface smoothness and the wear-resisting scratch resistance of product, improve hardness and the anti-ability of sinking of polishing-free primer of the present invention.
Preferably, described polishing-free primer also comprises the auxiliary agent of 1 ~ 3 weight part.
Preferably, described adjuvant component contains flow agent.
Preferably, described adjuvant component also contains one or more in siccative, toughner, defoamer, emulsifying agent, anti-skinning agent, wetting agent, sanitas, freeze-thaw stabiliser and the thickening material etc.
The present invention also provides a kind of polyurethane primer of polishing of exempting from, and the described polyurethane primer of exempting to polish is double-component polyurethane paint, comprises above-mentioned arbitrarily main lacquer, and isocyanate prepolymer.
Polishing-free primer provided by the invention is selected the anti-good short-oil alkyd of ability that sink, the anti-lower limit ability of improving product, utilize the sophistication on ultra-fine filling material surface, improved the surface smoothness of product, can save polishing to promote efficient and the profit of furniture producer.
