Abstract
The invention provides a kind of polishing-free primer, according to weight parts, comprising: short oil alkyd resin 50 ~ 80 weight part, solvent 5 ~ 15 weight part, filler 15 ~ 25 weight part, wherein, filler fineness is more than 3000 orders.This polishing-free primer selects the short-oil alkyd that anti-ability of sinking is good, and the anti-lower limit ability of improving product, make use of the sophistication on ultra-fine filling material surface, improves the surface smoothness of product, can save polishing with the efficiency and the profit that promote furniture producer.
Description
Technical field
The present invention relates to a kind of priming paint, particularly relate to one and exempt from polishing polyurethane primer and main paint thereof.
Background technology
Human being's production and make the history of painting pass up to the Stone Age.Confirm from a large amount of archaeological materials found, in the primitive society of distance before modern 7000, the mankind just use the grease of wild beast, myron and natural pigment etc. to prepare original covering with paint material, paint, to reach the object of decoration with feather, branch etc.Along with the progress of human society, after entering the Bronze Age, there is different progress ancient civilized country at that time directly utilizing crude substance to prepare in coating.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 to the The Spring and Autumn Period, the period of the Warring States can use raw lacquer and tung oil formulated coatings, has started the technology making used additives in coating, promotes paint development to a New Times.The paint coffin be unearthed from Changsha Han tomb at Mawangdui and the paint film of lacquerware tough and tensile, protective value is excellent, absolutely proves in B.C. 2nd century, the maturity that China uses the development of raw lacquer technology to reach.Enter eighties of last century, significant achievement and the succeeding in developing of various macromolecular compound of polymer science theory are put into production, for the New Times has been started in paint development.Succeeded in developing the special Synolac being used as the filmogen of coating the twenties in last century, from then on various synthetic resins newly developed is applied very soon in coating, makes coating enter to synthesize filmogen for the main epoch.
In modern furniture production, general coating is brushed very difficult smooth, so will carry out the brushing effect of polishing as below to beat what a smooth basal plane.The aesthetic property of furniture surface depends on the quality of polishing quality to a great extent.As everyone knows, in present Furniture manufacturing 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 is also between grinding machine, polishing workshop section is then most labor intensive, the workshop section that efficiency is the lowest, a general spraying workman, needs the polishing workman of collocation about 4, complex part even higher, says that to be tactics of human sea be not also.Due to singularity and the otherness of material itself, and component shape after processing and moulding etc. the opposite sex that is wanting in is also very large, adds limited machining functions and the cost consideration of sanding apparatus, does not also have the way replacing manual sanding well completely at present.And Furniture Manufacturing Enterprise is difficult due to personnel cost rising, improved efficiency in recent years, badly influence the profit of Furniture Manufacturing Enterprise.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide one to exempt from polyurethane primer of polishing, save polishing with the efficiency and the profit that promote furniture producer.
The invention provides a kind of main paint of exempting from polishing polyurethane primer, according to weight parts, comprising:
Short-oil alkyd 50 ~ 80 weight part;
Solvent 5 ~ 15 weight part;
Filler 15 ~ 25 weight part;
Wherein, filler fineness is more than 3000 orders.
Wherein, described solvent can be the mixture of one or more in esters solvent, aromatic hydrocarbon solvent, alcohol ether solvent, ketones solvent or 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.; 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 one in N-BUTYL ACETATE and 1-Methoxy-2-propyl acetate etc.
Wherein, filler can be selected from least one in calcium carbonate, talcum powder, transparent powder, pure aluminium silicate, calcium sulfate, barium sulfate, silicon-dioxide, mica and Calucium Silicate powder etc.
Preferably, described filler component contains talcum powder and transparent powder.
Preferably, described talcum powder is cosmetic-grade talc powder.
Transparent powder is a kind of non-metallic minerals, and transparency is high, and whiteness is good, refraction 1.54, density 2.3, and oil suction 25 is nonpoisonous and tasteless, acidproof durable corrosion, and the transparency is high.The refractive index of transparent powder itself and the refractive index of most synthetic resins closely, so the amount of filling out of transparent powder does not affect the transparency of finished product; The surface smoothness of product and wear-resisting scratch resistance can be improved, improve the hardness of polishing-free primer of the present invention and anti-ability of sinking.
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 is also containing one or more in siccative, toughner, defoamer, emulsifying agent, anti-skinning agent, wetting agent, sanitas, freeze-thaw stabiliser and thickening material etc.
Present invention also offers one and exempt from polyurethane primer of polishing, described in exempt from polishing polyurethane primer be double-component polyurethane paint, comprise above-mentioned arbitrary main paint, and isocyanate prepolymer.
Polishing-free primer provided by the invention selects the short-oil alkyd that anti-ability of sinking is good, the anti-lower limit ability of improving product, make use of the sophistication on ultra-fine filling material surface, improve the surface smoothness of product, polishing can be saved with the efficiency and the profit that promote furniture producer.
