Description
Technical field
The present invention relates to a kind of priming paint, particularly relate to and be a kind ofly applied to the polyurethane primer of melamine plate and the main paint of described priming paint.
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.Because Furniture manufacturing producer material, cost of labor increase, Furniture manufacturing producer has to do effort in reduction material cost and cost of labor, white furniture uses melamine material to account for significant proportion, and in Furniture manufacturing process, polishing operation consumes great amount of cost.
