Abstract
The invention discloses a multi-color coating method and a coated part; wherein, the method comprises at least the following steps: a layer of priming paint is coated on the whole face plate; a first middle paint is coated on a first area of the face plate; a first top finish is coated on the first middle paint; a second middle paint is coated on a second area of the face plate, and a second top finish is coated on the second middle paint. Since the method of using the same priming paint when coating two colors, the invention has the advantages of simplified paint coating process and improved yield rate.
Description
Technical field
The present invention relates to a kind of spraying production technology of plastic parts, in particular a kind of method of on plastic parts, carrying out multicolor spraying and by parts that this method obtained.
Background technology
Up to now, in the production of industrial quarters communication terminal equipment, often adopt on plastic parts, to spray, for example the shell of mobile phone as shell.And on mobile terminal device, often need the spraying of multicolour, especially on same parts.Double-colored spraying process on plastic parts mainly is that (the UV lacquer is the english abbreviation of Ultraviolet Curing Paint to employing UV lacquer, be ultraviolet light polymerization paint, also claim light-initiated coating, photocureable coating) and the method for PU lacquer (polyurethane paint is a kind of paint of occupancy volume maximum in market in the woodcare paint, can be divided into bicomponent polyurethane paint and single-component polyurethane paint) three sprays produce.
The UV lacquer is different with the film forming matter naming method with paint such as PU, PE, NC, the UV lacquer is to name with the curing mode of paint, it be by the automatic roller coat of machinery equipment, showering on furniture-plates or plastic plate face, under the irradiation of ultraviolet light (wavelength is 320-390nm), impel decomposition of initiator, produce free radical, cause the resin reaction, the instantaneous solidification film forming.
And when adopting the method for three sprays, common way is:
Play earlier one deck priming paint to reach adhesive force that increases between paint and the plastic parts and the needs that increase gloss; Be coated with in being then, the color of this layer is the required color of final effect; Uppermost one deck is a finish paint, is mainly used to reach the effect of high light, inferior light or rubberbase paint, also plays a kind of effect of protection simultaneously.
Three spray methods of prior art have nothing in common with each other for the prescription of the priming paint that UV coats with lacquer and the PU lacquer is used, middle japanning, finish paint, and what inconvenience uses separately on parts does not have; But when on same parts, doing double-colored spraying, for example do high light effect with certain color in the part of same parts, another part is done the rubberbase paint effect with another color, then can cause step various, complex process, the production cost height, the product yield is low, can't reach the requirement of heavy industrialization.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The object of the present invention is to provide a kind of method of multicolor spraying and the parts after the spraying thereof,, simplify spraying coating process, improve the product yield by adjusting spraying step and order.
Technical scheme of the present invention is as follows:
A kind of method of multicolor spraying may further comprise the steps at least:
A, on whole front panel spraying one deck priming paint;
B, spray lacquer in one first in the first area of described panel, and in described first, paint spraying first finish paint;
C, spray lacquer in one second, and paint spraying second finish paint in second at this at the second area of described panel.
Described method, wherein, lacquer coats with lacquer among the UV in described first, and described first finish paint is the UV finish paint; Lacquer is for coating with lacquer among the PU in described second, and described second finish paint is the UV finish paint.
Described method, wherein, described panel is a plastic rubber panel.
Parts after the described method spraying, wherein, described parts are provided with a plurality of color regions, and the priming paint of its each color region adopts same one deck; Corresponding middle lacquer and the finish paint that different colours is set on described priming paint.
Described parts, wherein, described parts are plastic parts.
Parts after the method for a kind of multicolor spraying provided by the present invention and the spraying thereof owing to adopted the mode of shared a kind of priming paint of double-colored when spraying, have been simplified lacquer spraying technique, have improved the product yield.
Description of drawings
Fig. 1 is the method flow schematic diagram of multicolor spraying of the present invention;
Fig. 2 is the method for multicolor spraying of the present invention and the painting process schematic diagram of the parts after the spraying thereof;
Fig. 3 is the cut-away view of the parts after the present invention spraying.
The specific embodiment
Below preferred embodiment of the present invention is described in detail.
Parts after the method for multicolor spraying of the present invention and the spraying thereof as shown in Figure 1, have adopted a kind of method of shared priming paint, and have simplified the step of double-colored spraying, have also solved simultaneously the difficult problem that the interface of two kinds of colors can't be handled.In double-colored spraying, owing to will reach high light UV and gorgeous color effect, must there be colory priming paint to deposit holder, the inventive method adopts a kind of technology of priming paint, make the interface single treatment, then in subsequent process, utilize the high rigidity characteristic of high light UV to support the finishing of production technology of PU lacquer, but promoted product quality and volume production.The present invention can be widely used in the double-colored and multicolor spraying on plastic cement, metal and other materials, below is that example describes with double-colored spraying mainly to the description of preferred embodiment of the present invention, but obviously scope of patent protection should not be limited in the double-colored spraying.
Multicolor spraying process of the present invention comprises: earlier on same panel once property be coated with priming, this priming paint can and PU in coat with lacquer and be complementary, also can well support the middle lacquer of UV; Coat among the UV the i.e. lacquer in first of lacquer above the priming paint of predetermined first area a on this panel, the face of painting in UV is again coated i.e. first finish paint of UV finish paint, as shown in Figure 2; And then coat among the PU the i.e. lacquer in second of lacquer at the priming paint of second area b, and then the face of painting in PU is coated the PU finish paint; Because of the PU lacquer damages than being easier to, and the high rigidity of UV lacquer can reduce damage, therefore, is coated with the UV lacquer earlier and can improves yield rate.
Parts after the method for multicolor spraying of the present invention and the spraying thereof, on same parts, scribble PU lacquer and UV lacquer, by priming paint only is coated with single treatment, and is coated with earlier among the UV and is coated with the mode that lacquer painting coats with lacquer among the PU again behind the lacquer painting lacquer, can utilize the high rigidity characteristics of UV lacquer, improve the finished product yield of product; And, owing to simplified spraying coating process, having improved production efficiency, parts of the present invention can carry out volume production.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
