Abstract
The invention discloses a spraying process for a surface of a hard luggage. The spraying process comprises the steps of: 1) spraying a layer of primer on the surface of a plastic base material after the plastic base material of the luggage is produced and molded, and roasting the primer at 65-75 DEG C for shaping for 25-35 min; 2) plating a metal plating layer on the primer layer of the luggage in a vapor deposition way; 3) spraying a layer of UV colored paint on the metal plating layer of the luggage and performing UV-irradiation on the UV colored paint at 50-60 DEG C for solidification for 40-50 min. As the film plating step is added in the spraying process for the surface of the hard luggage, the light reflective sense of the surface of the luggage is enhanced; as the UV colored paint is matched, the color diversification is realized, the hardness of the surface of the luggage is improved, the scratch resistance and friction resistance of the surface of the luggage are enhanced and the whole luggage is enabled to have a very strong metal texture.

Beneficial effect of the present invention is, the present invention by increasing metal coating step in hard case and bag surface spraying process, strengthened the reflective sense on case and bag surfaces, coordinate with UV colored paint simultaneously, not only realized the variation in color, promote the hardness on case and bag surfaces, strengthened the damage resistant rub resistance on case and bag surfaces, and made case and bag integral body embody a kind of very strong metal-like.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the case and bag face coat after spraying coating process spraying of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the specific embodiment of the present invention is described further.But the present invention is not limited in following embodiment, if without specified otherwise, the various paint classes that adopt in the present invention all can be bought gained by market.
The surface spray coating process of hard case and bag of the present invention, its detailed step is as follows:
1) case and bag go out after sheet metal forming with plastic rubber substrate, at substrate surface spraying last layer film thickness, be the colourless PU priming paint of 15 μ m～25 μ m, wherein: described plastic rubber substrate is one or both the composite material in PC, ABS, PVC, APS, PP, the composite material of preferred PC and ABS, the composite material that further preferably the weight ratio of PC:ABS is 7:3.This step, for strengthening the protective effect to base material, makes substrate surface more smooth, improves the adhesive force of substrate surface, for follow-up spraying is prepared;
2) case and bag that are coated with priming paint are put on baking production line and toasted and shape 25～35 minutes at 65～75 ℃;
3) take the mode of evaporation plates the coat of metal that one deck coating transmitance is 1～5% on the prime coat of case and bag, and to strengthen the reflective function on case and bag surface, evaporation mode herein can realize with existing evaporation coating method, does not repeat them here its specific embodiment;
4) according to the colour planning requirement of case and bag, on the coat of metal of case and bag, spraying last layer film thickness is the UV colored paint of 10 μ m～20 μ m, and at 50～60 ℃, pass through 35～45 seconds solidifying and setting of UV-irradiation, wherein, the irradiation energy of ultraviolet light is 800～1000mj/cm
2;
5) the colored paint layer surface spraying last layer film thickness at case and bag is the UV finish paint of 35 μ m～45 μ m, the hardness of described UV finish paint is 1-2HB, then at 50～60 ℃, through UV-irradiation, solidify 40～50 seconds, wherein, UV-irradiation energy is 900～1100mj/cm
2.
By above-mentioned spraying coating process, after the surface of case and bag is processed, the coating structure on case and bag surface as shown in Figure 1, on base material 1, is followed successively by from bottom to top layer: prime coat 2, the coat of metal 3, UV colored paint layer 4 and UV top coat layer 5.
