Description
Technical field
The present invention relates to the closed coating process of woodwork of hotel man Furniture, Home furniture, timber, bathroom, particularly relate to carving woodwork, be fixedly mounted with the closed coating process of the wood furniture such as goods, timber and manufacture method.
Background technology
Along with reform and opening-up is over 30 years, the raising of people's quality of life, people are more and more higher to life furniture requirements, and furniture design is all with personalization, and the carving of differentiation, technique are linear and be fixedly mounted with as major design theory.To the plentiful effect of the paint of wood-based product, the grain of wood has very large requirement, particularly hotel man Furniture, timber, wooden sofa, bedside cupboard, dressing table, dining table, dining chair, bathroom is all with carving usually, the appearance design of technique line style is main, cause complex process, produce loaded down with trivial details, recruitment is many, paint cost is high, coating process technique is many, polishing often, production cycle is long, this kind of furniture cannot adopt roll coating process to complete coating paint technique substantially, the product of major part wood furniture enterprise all adopts repeatedly spraying or once sweeps painting and repeatedly sprays painting technology again, current this kind of wooden product enterprises is all adopt following methods to complete paint coating process:
1, the construction technology being coated with PU paint is swept
Sweep the construction technology efficiency being coated with PU paint low, the time is long.Because PU solid content only has 40%, other are all organic solvents, general construction all will sweep painting three to four times, and all want 4-8 hours drying time at every turn, require that place is large, after each drying, all will repeat polishing, and polish and time-consumingly to require great effort, and when sweeping painting, PU white spirit content is high, volatilization is fast, viscosity B coefficent is fast, and the flatness of painting is swept in very difficult control.Fillibility can be caused poor if increase solvent, it is serious that trace then swept by minimizing solvent, abnormity place heap oil is difficult, the large shaped wooden product of major part enterprise can adopt the method for direct spraying, small pieces employing is swept painting and is once sprayed three techniques again, there is the paint of 1/3rd can be sprayed on workpiece during spraying, all the other all fly out outside workpiece, very large by oil mass, and drop into substantial contribution and build paint spray booth, drying shed, same drying time is very long, efficiency is low, will in strict accordance with main paint during the construction of PU paint: curing agent: the ratio paint of diluent=1:0.5:0.8, and need after construction could dryly to polish after 8-12 hour, common workpiece all will spray three to four times, just can reach the requirement of primer painting, wherein carving part, profiled piece, be difficult to be sprayed onto position, difficulty of construction is large.And the awareness of safety of polishing workman is also in improve now, young man is scarcely ready to be engaged in this work post of polishing, and enterprise is difficult to recruit suitable polishing work.In the process in order to good filling PU needs to use a large amount of inserts such as talcum powder, calcium carbonate, barium sulfate, the transparency of the many meetings of powder on paint has impact, and powder content has lacked difficult polishing.Needed repeatedly spraying in the construction technology of PU paint and repeatedly polished, the solvent of PU paint is generally organic solvent, is mainly aliphatic hydrocarbon, aromatic hydrocarbon, alcohol, ketone, benzene, dimethylbenzene equal solvent.Wherein benzene class and ketones solvent cause serious environmental pollution, also can cause very large injury to operating personnel's health, and it is also difficult that the paint simultaneously flown out during spraying forms paint rubbish, needs professional unit assist process, add operating cost; The project to the keeping under strict supervision close inspection of environmental disruption great pernicious gas Ye Shi national environmental protection department of discharge.
