Abstract
A surficial spray coating technology by use of water stream for generating a random pattern effect on the surface of workpiece includes such steps as surface treating, painting, water stream treating spray coating, and spraying brightening oil.
Description
Technical field
The present invention relates to a kind of external coating technology, more specifically, relate to a kind of current that utilize and carry out the technology that face coat is handled, adopt this technology can obtain personalized coating result.
Background technology
Generally workpiece such as plastic parts are carried out external coating, the finished color dullness that obtains lacks attractive in appearance.For realize at plastic rubber member surface having special-effect decorative pattern and pattern, 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 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; Simultaneously, the painting effect that traditional coating process obtains has whole same color often or carries out application according to pre-set pattern form, can not obtain fashion and personalized pattern or effect of decorative patterns.Therefore, seek a kind of coating process with low cost, easy and simple to handle, can reach special, individual decoration effect of requirement again, just become the direction that industry is made great efforts.
Summary of the invention
The object of the present invention is to provide a kind of external coating technology, by this technology can obtain having fashion at surface of the works such as plastic parts, the painting effect of personalized lines.
The technical scheme that the present invention adopts for achieving the above object is, provides a kind of current that utilize to carry out the technology that face coat is handled, and it is characterized in that, comprises following processing step:
A) surface treatment: pending surface of the work is cleaned also air-dry;
B) apply coating: apply one deck aqueous paint in the mode that sprays or brush at pending surface of the work;
C) current are handled: before the complete mummification of painting layer, the guiding current flow through this face coat equably, and coating produces different lines under the souring of current;
D) mummification: take out workpiece, dry naturally or dry;
E) blast finishing ink: handle through current and mummification after surface of the work on application one deck gloss oil equably, mummification, promptly.
The current that utilize provided by the invention carry out the technology that face coat is handled, and pending surface of the work are cleaned at least a in further comprising the steps of in step a): a1) remove greasy dirt; A2) remove releasing agent; A3) remove surface dirt; A4) remove surface irregularities; And a5) with solvent or diluent with surperficial scrub.
The current that utilize provided by the invention carry out the technology that face coat is handled, and described pending workpiece is that plastic parts, timber, metalwork or metal-plastic composite members etc. can be carried out the object that application is decorated arbitrarily.When the workpiece for the treatment of application is timber, before step b) applies coating, also be included in wood surface apply one deck priming paint and polish flat, the step of mummification.
In the technology of the present invention, also be included in and apply the preceding step that employed paint is diluted of coating, in the paint after the dilution, paint: solvent or diluent 〉=1: 10.
The current that utilize provided by the invention carry out the technology that face coat is handled, the mode that described guiding current flow through face coat is to apply on cated this surface of the work with the water spray or towards being spread across, spray or dash the surface area size that the distance spill between device and the workpiece looks this workpiece and adjust makes water this surface of the work of flowing through equably; The time length of washing away is decided on the required effect that obtains lines, and flushing time is long more, and the lines color effects that remains in surface coating is just light more, otherwise the color effects of lines is just dense more.
In order to obtain local painting effect, before applying coating, step b) can also will treat that the application surface of the work does not need the part of application to cover, and throws off this cover layer again after disposing with gummed paper or other waterproof adhesive material.
Implement the current that utilize provided by the invention and carry out the technology that face coat is handled, its beneficial effect is, this process is simple, processing ease, with low cost, and what obtain is the application layer of not specific lines effect.Fashion-orientation, the personalised look that can be widely used in digital product such as computer, mobile phone and various household electrical appliance, furniture, ornament etc. are decorated.Adopt technology of the present invention, its cost is the about 1/4th of other method at present, thereby greatly reduces the cost of product.
Description of drawings
Fig. 1 is an embodiment operation chart of technology of the present invention.
Fig. 2 is another embodiment operation chart of technology of the present invention.
The specific embodiment
One embodiment of the present of invention are got the laptop computer outer cover plate plastic plate 10 after the punch forming as shown in Figure 1, and the dust and the foreign material on surface are removed in cleaning, remove with the solvent or diluent wiping and remain in surperficial releasing agent and greasy dirt etc., and are air-dry; Brushing one deck water colour paint on this plastic plate is placed on spray head 11 times with this plastic plate then, opens the water source and carries out trickle, and the distance between plastic plate and the spray head just is in fully with this plastic plate within the scope of the water that sprays is advisable; Towards the pouring time about 10 minutes, the lines color effect that concrete duration optionally obtains and suitably reduce or increase; Dash to drench finish after, take out this plastic plate, after drying naturally, evenly spray one deck gloss oil, dry and promptly get laptop computer outer cover plate with water wave decorative effect.
Embodiment 2
An alternative embodiment of the invention is got the composited aluminum and plastic decking 12 after the punch forming as shown in Figure 2, and the dust and the foreign material on surface are removed in cleaning, removes and remains in surface and oil contaminant, and is air-dry; Brushing one deck water colour paint on this composite plate, then this plate being placed on the porous that is connected to water pipe 13 coils 14 times towards spilling, open the water source and carry out trickle, should dash the big or small similar of the size spill dish and this composite plate, composited aluminum and plastic decking with dash the distance of spilling between the dish with from when spilling composite plate, being unlikely to the paint on the composite plate splash and being advisable towards spilling the water that coils under the pouring; Towards the pouring time about 5 minutes, the lines color effect that concrete duration optionally obtains and suitably reduce or increase; Dash to drench finish after, take out this plastic plate, oven dry; Last evenly spraying one deck gloss oil dries, and promptly gets the composited aluminum and plastic decking with water wave decorative effect.
