In another prior art, use the method for repeatedly spraying paint, make double-colored or polychrome case of electronic device, wherein, earlier partial shell is covered with covering, to unsheltered housing parts spray base and finish paint, then, hide the part of having sprayed paint with covering, and the part of not spraying paint is sprayed the priming paint and the finish paint of another kind of color.Spray paint for four times and obtain double-color shell.Because surface lacquer, metallic paint for example, the housing appearance looks elegant is glossy, and texture is good, and corrosion-resistant, attracts the human consumer.
But the deficiency of this method is, needs at least one covering corresponding with the surface of shell shape, also has the pickup groove of fixing this covering on the housing, increased the quantity and the complexity of mould for this reason, increased production cost.Another deficiency is, will install and remove covering in turn when spraying paint, and increases operation, and double-color shell must four times spray paint (twice priming paint, twice finish paint) just can obtain, and production efficiency is lower.A defective again of this method is, this method itself has determined the fraction defective height, and covering cooperates pine with pickup groove, and a kind of lacquer of color will invade another color part of surface of shell through the slit, cause substandard products; And if covering cooperates tension with pickup groove, after then spraying paint, covering takes off difficulty, easily lacquer painting is peeled off, and forms substandard products; The intersection of two kinds of lacquers on the housing, because the flowability of lacquer forms sawtooth or wavy line, it is attractive in appearance that obscure boundary influences housing.
Summary of the invention
The method for paint spraying that the purpose of this invention is to provide a kind of plastic casing is used to make the double-colored of electronic installation or polychrome housing.
Another object of the present invention provides a kind of method for paint spraying of plastic casing, must not use covering and production cost is lower, simple to operate and production efficiency height.
A further object of the present invention provides a kind of method for paint spraying of plastic casing, is difficult for producing substandard products
According to the present invention, a kind of method for paint spraying of plastic casing is provided, comprising: housing that has two kinds of colors at least of injection moulding is characterized in that: spray a kind of priming paint of printing opacity on the surface of above-mentioned housing, for example contain the priming paint of pigments, mica powder.The kind of the color of housing can change as required.For example the raw material by two or more different colours can injection moulding obtain double-colored or pleochroic housing respectively as three looks.Because being sprayed on the prime coat of surface of shell is printing opacity, refraction and transmission take place by enamelled coating in light, be that the part transmitted light is absorbed by housing, and the housing of different colours can absorb the visible light of different-waveband, thereby present at least two kinds and not only be different from the case material color but also be different from the new color that coats with lacquer color, thus, only use a kind of lacquer, but can obtain at least two kinds of colors on the surface of housing.
The method according to this invention, above-mentioned priming paint can adopt various mica lacquers.For the present invention, mica lacquer is the lacquer that contains the pigments, mica powder, is the priming paint of common printing opacity, and the pigments, mica powder can be bought from the market.When the mica lacquer is sprayed on surface of shell, during for example greyish black double-color shell surface, because its mica paint film is printing opacity, part light projects on the housing through priming paint and is absorbed, the part visible light reflects in addition, and ash, black surface present ash discharge, black color in addition respectively originally.Paint part not simultaneously when the mica of selecting for use, the color that housing presents also has multiple variation thereupon.Can satisfy human consumer's different colours hobby thus.
The method according to this invention behind surface of shell spraying priming paint, sprays the finish paint of layer of transparent again.The effect of finish paint is a waterproof, wear-resisting, protection priming paint.Finish paint selects for use the polyester lacquer as polyurethane paint usually, perhaps ultraviolet solidified paint (uV lacquer).Change different finish paints, can change the gloss of housing outward appearance, obtain various effects, for example, Gao Guang, the effect of middle light or inferior light has been enriched the color and luster kind of housing, for the human consumer provides abundant selection may.
The present invention also provides a kind of manufacture method of plastic casing, comprising: (1) is had the housing of two kinds of colors at least at least by the raw material injection moulding of two kinds of different colours; (2) spray a kind of priming paint of printing opacity on the surface of above-mentioned housing.Behind above-mentioned surface of shell spraying priming paint, or spray the finish paint of layer of transparent again.Priming paint can coat with lacquer for mica.Finish paint can be lance ester lacquer or ultra-violet curing lacquer.
In the present invention, the equipment of the double-shot moulding equipment of housing and spraying priming paint, finish paint can adopt the affair of establishing in the prior art, does not give unnecessary details at this.
Utilize method of the present invention, need not to use covering and pickup groove, saved die cost.Simultaneously, save the operation of installing and taking off covering, and only needed twice spraying (priming paint, a finish paint), simplified lacquer spraying technique, reduced cost.In addition, spray has avoided different lacquers to invade mutually because of flowing at intersection with a kind of priming paint on the plastic casing, forms waste product, thereby has improved the percentage of A-class goods.
