According to the technical scheme, electrostatic precipitation is carried out on the substrate surface after the substrate surface is cleaned; wrinkle paint is sprayed, and the thickness of the wrinkle paint coating is 30-200 microns; then the substrate surface is baked through infrared rays for 2-3 hours, and the temperature is 120-150 DEG C; the substrate surface is cooled at room temperature for 2-4 hours, then vacuum evaporation coating is carried out, and the thickness of the coating layer is 50-500nm; ultraviolet light polymerization finish paint is sprayed, and the thickness of a finish paint coating is 10-30 microns; then ultraviolet irradiation is carried out, the finish paint is cured, the irradiation time is 5-10 seconds, and the surface is made to be provided with the natural wrinkle grains. The defects in the prior art are overcome, the heat curing type wrinkle paint is combined with the vacuum coating, and the substrate surface is made to be provided with the wrinkle grains with metallic luster.
Description
Technical field
The invention belongs to technical field of substrate surface treatment, be specifically related to a kind of surface of bottom material treatment process making surperficial tool wrinkle texture.
Background technology
Industrial art paint is that a class can protect surface of bottom material to present different textures simultaneously, makes article have more the heat curing coating of aesthetic feeling, and principal item has wrinkle finish, hammer paint, crackle paint, crystallizing finish and tangerine shape paint etc.The one-tenth line principle of novelty finish mainly adds the additive with specific physicochemical property in coating, by controlling drying time, bake out temperature and cool time after spraying, makes the texture that surface presentation is different.At present, generally believe in the industry, tradition heat cure novelty finish cannot combine with vacuum coating, because low boiling, high volatile solvent produce whirlpool due to the quick volatilization of solvent in coating dry run in heat cure novelty finish, destroying the planarization of coating, there is more pin hole and defect in film coated surface; And the solvent adopting boiling point higher, during baking film forming, although solvent volatilization is conducive to obtaining even curface effect more slowly, the residual solvent in cured film is difficult to Ex-all, will overflow during vacuum coating from priming paint, affects coating quality.Thus, when novelty finish and technique for vacuum coating combine spraying ground, novelty finish and the membrane-bound fastness of plating not, are very easy to the phenomenon occurring falling paint.
Summary of the invention
The technical problem to be solved in the present invention is, overcome the defect of prior art, a kind of surface of bottom material treatment process making surperficial tool wrinkle texture is provided, specifically the wrinkle finish of thermohardening type and vacuum coating is combined, make substrate surface present the process of surface treatment of tool metallic luster wrinkle texture.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Make the surface of bottom material treatment process of surperficial tool wrinkle texture, it is characterized in that, it comprises the following steps:
(1) surface cleaning: the dust of surface of bottom material, oil stain, spot etc. are thoroughly clean clean, then electrostatic precipitation;
(2) spray wrinkle finish: spray wrinkle finish, wrinkle finish coating layer thickness is 30-200 μm;
(3) dry: infrared ray baking 2-3 hour, temperature is 120-150 DEG C;
(4) cool: under room temperature, cool 2-4 hour;
(5) vacuum coating: vacuum vapor plating, film plating layer thickness is 50-500nm;
(6) topcoating: spray UV-curable finish coat, the thickness of topcoat is 10-30 μm;
(7) ultraviolet light polymerization: UV-irradiation, makes topcoating cures, and irradiation time is 5-10 second.
Described ground is glass or high-temperature resistance plastice, and described high-temperature resistance plastice can tolerate the high temperature of more than 120 DEG C.
Described ground first sprays one deck heat cure priming paint, after being heating and curing, spray wrinkle finish again.
Described wrinkle finish coating layer thickness is 100-150 μm.
Described baking step, infrared ray baking time is 2-2.5 hour, and temperature is 140-150 DEG C.
Adhesion promoter is added in described finish paint.
The consumption of described finish paint and adhesion promoter adds 1-1.5 weight portion adhesion promoter in 100 mass parts finish paints.
Advantage of the present invention and beneficial effect:
First, instant invention overcomes the heat curing coating generally believed in the industry and cannot be combined the technology prejudice of carrying out surface of bottom material process with vacuum coating, by reducing infrared ray baking temperature, extend the method for baking time, solve because in coating, more pin hole and defect appear in solvent volatilization, in cured film, residual solvent is difficult to Ex-all, affects coating quality, cause heat cured novelty finish and plated film conjugation firm not, easily occur the technical problem of depainting phenomenon; Secondly, the present invention is suitable for the process of glass or frosting, only according to the difference of material surface roughness, need spray ultraviolet cured primer adaptively, ensure that the firmness of surface-treated layer; Again, invention provides for the thickness of novelty finish spraying, while ensureing plated film firmness, the wrinkle texture of different thicknesses can be obtained, meet the esthetic requirement of different people; Finally, the present invention is added with the finish paint of adhesion promoter by spraying, and while protective coating makes it have more firmness, the performances such as surface flatness, brightness, hardness, chemicals-resistant corrosion strength are significantly increased.
