Abstract
The invention provides a main paint and a primer which are applied to a melamine board. The main paint comprises the following components in parts by weight: 18-35 parts of alkyd resin, 5-15 parts of hydroxy acrylic resin, 3-7 parts of anti-settling thickening agent, 6-10 parts of solvent and 40-60 parts of padding. The hydroxy acrylic resin in the main paint has the advantages of high hardness, high drying speed, good weather resistance and the like and is matched with the alkyd resin for use to increase the adhesive force of paint. The primer containing the main paint provided by the invention can be directly sprayed on the melamine board without polishing the melamine board, thus the labor cost is saved.
Description
Technical field
The present invention relates to a kind of priming paint, relate in particular to a kind of polyurethane primer of melamine plate and main paint of described priming paint of being applied to.
Background technology
Human being's production and make the history of painting can pass up to the Stone Age.From a large amount of archaeological materials of having found, confirm, the primitive society before apart from modern 7000, the mankind have just used the original covering with paint materials of preparation such as grease, myron and natural pigment of wild beast, with feather, branch etc., are painted, 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 directly utilizing aspect crude substance preparation 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 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.From the Changsha Han tomb at Mawangdui, the paint film of unearthed paint coffin and lacquerware is tough and tensile, and the protective value excellence, absolutely proved in B.C. 2nd century, the maturity that China is used 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 Synolac of the special filmogen as coating the twenties in last century, from then on various synthetic resins newly developed is applied very soon in coating, coating is entered and take and synthesize filmogen as the main epoch.
In the modern furniture production, general coating is brushed and is difficult to smoothly, so will polish, beats what a smooth basal plane 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 is also between grinding machine, polishing workshop section is labor intensive, the workshop section that efficiency is the lowest, a general spraying workman, the polishing workman of 4 left and right of need to arranging in pairs or groups, complex part even higher, say that tactics of human sea was not yet.Because furniture manufacturer material, cost of labor increase, furniture manufacturer has to do effort on reduction material cost and cost of labor, white furniture is used melamine material to account for significant proportion, and in the furniture production process, the polishing operation has consumed great amount of cost.
