Description
Technical field
The invention belongs to surface of bottom material processing technology field, be specifically related to a kind of process of surface treatment that makes surperficial tool blast line 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 is mainly in coating, to add the additive with specific physicochemical property, after spraying, by controlling drying time, bake out temperature and cool time, makes surface present different textures.At present, generally believe in the industry, tradition heat cure novelty finish cannot combine with vacuum coating, because the quick volatilization due to solvent in coating dry run of low boiling, high volatile volatile solvent produces whirlpool in heat cure novelty finish, the planarization that destroys coating, there is more pin hole and defect in film coated surface; And adopt the higher solvent of boiling point, during baking film forming, although solvent evaporates is conducive to obtain even curface effect more slowly, the residual solvent in cured film is difficult to Ex-all, during vacuum coating, will from priming paint, overflow, and affects coating quality.Thereby novelty finish and technique for vacuum coating are in conjunction with spraying during ground, novelty finish and the membrane-bound fastness of plating are inadequate, are very easy to occur falling the phenomenon of 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 that makes surperficial tool blast line texture is provided, specifically blast line paint and the vacuum coating of thermohardening type are combined, make substrate surface present the process of surface treatment of tool metallic luster blast line texture.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The surface of bottom material treatment process that makes surperficial tool blast line texture, 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 cleaned totally, then electrostatic precipitation;
(2) spray blast line paint: spray blast line paint, blast line lacquer coat thickness is 50-250 μ m;
(3) dry: infrared ray baking 1.5-2.5 hour, temperature is 170-200 ℃;
(4) cooling: cooling 1-2 hour under room temperature;
(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 μ m;
(7) ultraviolet light polymerization: UV-irradiation, finish paint is solidified, irradiation time is 5-10 second.
Described ground is glass or high-temperature resistance plastice, and described high-temperature resistance plastice can tolerate 170 ℃ of above high temperature.
On described ground, first spray one deck heat cure priming paint, after being heating and curing, spray again blast line paint.
Described blast line lacquer coat thickness is 100-150 μ m.
Described baking step, infrared ray baking time is 2-2.5 hour, temperature is 170-180 ℃.
In described finish paint, add adhesion promoter.
The consumption of described finish paint and adhesion promoter is in 100 mass parts finish paints, to add 1-1.5 weight portion adhesion promoter.
Advantage of the present invention and beneficial effect:
First, the present invention has overcome the heat curing coating generally believing in the industry cannot be combined with vacuum coating the technology prejudice of carrying out surface of bottom material processing, by reducing infrared ray baking temperature, extend the method for baking time, solved because more pin hole and defect appear in solvent evaporates in coating, 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 processing of the applicable glass of the present invention or frosting, only need spray ultraviolet cured primer adaptively according to the difference of material surface roughness, has guaranteed the firmness of surface-treated layer; Again, the present invention has stipulated the thickness of novelty finish spraying, when guaranteeing plated film firmness, can obtain the wrinkle texture of different thicknesses, has met different people's esthetic requirement; Finally, the present invention is added with the finish paint of adhesion promoter by spraying, and when protective coating makes it have more firmness, the performances such as surface flatness, brightness, hardness, chemicals-resistant corrosion strength are significantly increased.
