Abstract
A surficial spray coating technology by use of airflow for generating a random pattern effect on the surface of workpiece includes such steps as surface treating, painting, airflow spray coating, and spraying brightening oil.
Description
Technical field
The present invention relates to a kind of surperficial spraying technology, more specifically, relate to a kind of technology of utilizing air-flow to carry out the surface spraying, adopt this technology can obtain personalized spraying effect.
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 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 solid color that the spraying effect that traditional spraying coating process obtains is whole often or spray according to pre-set pattern form can not obtain fashion and personalized pattern effect.Therefore, seek a kind of spraying 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 surface spray coating process, the spraying method by this technology can obtain having fashion at random at surface of the works such as plastic parts, the decorative pattern or the pattern of individual decoration effect.
The technical scheme that the present invention adopts for achieving the above object is, a kind of technology of utilizing air-flow to carry out the surface spraying is provided, and it is characterized in that, comprises following processing step:
A) surface treatment: before spraying, flat workpiece surface to be sprayed is cleaned also air-dry;
B) apply paint: the workpiece that horizontal positioned is to be sprayed, and on predefined at least one position of surface of the work, drip predefined a certain amount of paint;
C) air-flow spraying: one or more air stream outlets that are connected with flow generator are aimed at the paint that drips on the surface of the work to be sprayed, open flow generator, paint produces one deck in the motion of the effect lower edge of air-flow airflow direction at surface of the work and has the coating of random pattern;
D) blast finishing ink: on the surface of the work after the air-flow spraying, spraying one deck gloss oil equably, mummification, promptly.
The technology of utilizing air-flow to carry out surface spraying of the present invention is cleaned at least a in further comprising the steps of 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.
The technology of utilizing air-flow to carry out surface spraying of the present invention, described workpiece to be sprayed are the objects that plastic parts, timber, metalwork or glass etc. with flat surface can carry out spraying and decorating arbitrarily.When workpiece to be sprayed is timber, before step b) applies paint, 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, employed paint is the water-based quick drying paint preferably, and the viscosity of this kind paint is relatively low, good fluidity and easily mummification, is suitable for mechanization water operation of the present invention.
In the technology of the present invention, in order to obtain having the pattern effect of same color or different colours, be with a kind of color or color not of the same race at the paint that lip-deep diverse location applied of workpiece to be sprayed.
Carry out in the surperficial technology that sprays at the air-flow that utilizes of the present invention, the diameter of the air stream outlet of described flow generator is 0.5～1.5mm, so that paint has suitable diversity in flowing; In the spraying process, distance between the paint of air stream outlet and dropping is 1～20cm, stream pressure is 3.0～6.0Kgf/cm2, and the big I of jet opening distance and spray pressure is made suitable adjustment according to the needed pattern distribution situation of area size, the viscosity size of paint, surface of the work of degree surface of the work to be painted; The angle of the surface of the work of airflow direction and horizontal positioned can be arbitrarily angled in the spraying, also can adjust arbitrarily according to relative position and the required effect that obtains pattern that paint is applied to surface of the work in the concrete operations.
In order to obtain local spraying effect, before applying paint, step b) can also not need the spraying part to cover surface of the work to be sprayed with gummed paper or other adhesive material, after finishing, spraying throws off this cover layer again.
Implementing the beneficial effect that the technology of utilizing air-flow to carry out surface spraying provided by the invention has is, this process is simple, processing ease, with low cost, obtain be at random, the sprayed coating of specific pattern effect not, 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 a technological operation schematic diagram of the present invention.
The specific embodiment
Embodiment 1
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; The nameplate location for paste default in this plastic plate lower left corner drips several blue water-based paint 11, then with air gun 12 with approximately with the angle of panel angle at 45 along the upper right side to aiming at these paint, the about 1cm of distance of puff prot and paint, the bore of regulating puff prot is at about 0.5mm; Open air valve, adjustments of gas pressure is at about 3.0Kgf/cm
2, utilizing air-flow that paint is dripped and purge, paint drips 11 and spread on plastic plate 10 at the effect lower edge of gas airflow direction, thus generation has the coating 13 of random pattern; After treating this coating mummification, evenly spray one deck gloss oil on plastic parts 10 surfaces, mummification gets product.
Embodiment 2
Get to decorate and use composited aluminum and plastic decking, the dust and the foreign material on surface are removed in cleaning, remove with the solvent or diluent wiping and remain in surperficial greasy dirt etc., and are air-dry; On near the several position the edge of this aluminium-plastic panel, drip the several paint that color is identical or inequality respectively, then with several air guns respectively to aim at these paint one by one along the direction relative with this edge with the angle that panel becomes 30～60 ° of angles, the distance of puff prot and paint is in 20cm, and the bore of regulating puff prot does not wait at 0.5～1.5mm; Open air valve, adjustments of gas pressure is at about 3.0～6.0Kgf/cm
