Abstract
A surficial spray coating technology for generating the pattern effect on the surface of workpiece includes such steps as surface treating, covering with a mesh, spray coating, drying, and spraying brightening oil.
Description
Technical field
The present invention relates to a kind of chemical process technology, more specifically, relate to a kind of spraying coating process, can obtain the coating of different decorative patterns or pattern effect by this technology at surface of the work at surface of the work.
Background technology
Generally workpiece such as plastic parts are carried out the just application of solid color of surface spraying, the finished color dullness that obtains lacks attractive in appearance.In order to realize having decorative pattern special-effect or that have multiple color and pattern at plastic rubber member surface, industry has been developed new and high technologies such as printing in the film, water transfer printing in recent years.But the equipment input of the employing Yin Gaoang of new and high technology and bring has expensively simultaneously also increased the technology difficulty and has reduced production efficiency, and this is under the overall situation of current industry keen competition, and the high-efficiency and low-cost of pursuing with industry requires and fails to agree.Therefore, seek a kind of spraying coating process with low cost, easy and simple to handle, can reach the requirement of special-effect again, just become industry the direction of constantly making great efforts.
Summary of the invention
The object of the present invention is to provide a kind of surface spray coating process, this technology is by the method decorative pattern or the pattern that can obtain having special-effect at surface of the works such as plastic parts of spraying, satisfies under the different situations needs to the workpiece outward appearance.
The technical scheme that the present invention adopts for achieving the above object is, a kind of surface spray coating process is provided, and it is characterized in that, comprises following processing step:
A) surface treatment: before spraying, surface of the work to be sprayed is cleaned also air-dry;
B) cover guard: on the surface of the work after the processing, cover the guard that one deck designs decorative pattern or pattern in advance;
C) spraying: to covering Workpiece painting one deck paint of guard, thereby obtain having the guard decorative pattern that designs in advance or the coating of pattern effect, take off guard at surface of the work;
D) mummification: static at normal temperatures drying 10～20 minutes after spraying finishes, take off guard;
E) blast finishing ink: evenly spray one deck gloss oil and mummification at plastic rubber member surface, promptly.
Surface spray coating process of the present invention cleans at least a in may further comprise the steps in step a): a1) remove greasy dirt to surface of the work to be sprayed; A2) remove releasing agent; A3) remove surface dirt; A4) remove surface irregularities; And a5) with solvent or diluent with surperficial scrub.
Surface spray coating process of the present invention, described workpiece to be sprayed are the objects that plastic parts, timber, metalwork or glass etc. with flat surface or curved surface can carry out spraying and decorating arbitrarily.When workpiece to be sprayed is timber, before covering guard, step b) also is included in the step that wood surface applies one deck priming paint and mummification.
Described guard is that flexible material is made, and guard is looked the difference of various workpiece and had different specification shapes, and the thickness of the employed netting twine of guard and the mesh on the guard distribute and also look different decorative patterns or pattern and the density difference.
Surface spray coating process of the present invention, described spraying method are to adopt artificial or mechanical system is carried out some a spray or an integral spray, and the paint that is adopted is aqueous paint or common PP (unsaturated polyester resin) or PU (polyurethane resin) paint; When adopting common PE or PU paint, take off guard after the paint mummification to be sprayed again.When adopting the mechanical system spraying, need to require and the operating condition of pre-set mechanically spraying according to the pattern in the different production batch in advance, as manipulator travel speed, paint supply, spray pressure etc., pre-set needed different paint kind simultaneously.
Mummification operation in the technology of the present invention can be by drying device oven dry 5～10 minutes, also can be at room temperature to dry naturally 10～25 minutes.
Surface spray coating process of the present invention, before the step e) blast finishing ink, coating patterns or the color requirement required according to surface of the work, can also one or many repeating step b), c) and d), obtain the effect of different colours and/or different floral designs at workpiece by repeatedly spraying, this effect can be to have the floral designs of marbling effect or the floral designs of other suitable effect.Wherein, successively for several times have different colours or concentration at the paint of surface of the work spraying, the situation of the thickness view case of the color of paint of spraying and every kind of color needs and does suitable adjustment; Simultaneously, successively for several times at the paint of surface of the work spraying preferably with a kind of paint of matrix, to produce repulsion between the paint of avoiding physico-chemical property to differ greatly or to react, paint selection view case effect and decide, general aqueous paint can obtain the floral designs of plane effect, and common PE or PU paint then can obtain having relief effect.
Surface spray coating process of the present invention, described guard is looked various varying in size of workpiece and is had different specification shapes, guard can whole cover surface of the work, also can partly cover on the surface of the work, and the mesh on the guard distributes and also looks different decorative patterns or pattern and the density difference.
Surface spray coating process of the present invention also comprises the step of prefabricated one or more guards, and comprises the step of changing different spraying utensils, with the different different paint of sprayer spraying.
Implement surface of the work spraying coating process provided by the invention, the beneficial effect that has is, simple, the processing ease, with low cost of this process, the personalised look that can be widely used in digital product such as computer, mobile phone and various household electrical appliance, furniture, ornament etc. is decorated.The workpiece that the surface of adopting technology of the present invention to obtain has different colours and/or different floral designs effects, its cost are the about 1/4th of other method at present, thereby greatly reduce the cost of product.
