Abstract
The invention discloses a surface treatment shielding method, comprising the following steps: blending a coating, coating the inner wall of a hole of a work-piece with the coating, and solidifying the coating to form a protective film covering the inner wall of the hole so as to prevent the inner wall of the hole from being subjected to surface treatment, wherein the coating resists surface treatment, and comprises resin and a solvent; the surface tension of the coating is smaller than or equal to 22mN/m. The surface tension of the coating is smaller than or equal to 22mN/m, so that the coating easily forms an intact protective film on the inner wall of the hole, and the protective film is not easily broken even if the hole is complicated in structure, and thus the problem that a rubber plug cannot be completely attached to the inner wall of the hole, easily generated in protection by adopting the rubber plug is avoided.
Description
Technical field
The present invention relates to a kind of surface treatment masking methods, relate in particular to a kind of method of in the time of surface treatment, workpiece eyelet being covered.
Background technology
When workpiece surface is processed, as application, baking vanish, sandblast, plating, anodic oxidation, electrophoresis etc., the eyelet with specific function of offering on workpiece does not need to carry out above-mentioned processing, therefore need in surface treatment process, be covered protection.Conventional method is to adopt protection gum cover that eyelet is stopped up at present, thereby the reactant while avoiding surface treatment enters eyelet.But, when as more complicated in cell structure, the protection gum cover more difficult eyelet that stops up completely, or when eyelet hour, protection gum cover easily comes off, protection poor effect.
Summary of the invention
In view of above content, be necessary to provide preferably surface treatment masking methods of a kind of protection effect.
A kind of surface treatment masking methods, it comprises the following steps: allotment coating, the resistance to surface treatment of this coating, it comprises resin and solvent, the surface tension of this coating is less than or equal to 22 milli Newton/meter; Be coated with this coating in workpiece hole intraocular wall; And, coating material solidified, thus the protective membrane that covers this eyelet inwall formed, to prevent that this eyelet inwall is by surface treatment.
Because the surface tension of coating is less than or equal to 22mN/m; coating easily forms complete protective membrane at the inwall of eyelet; even cell structure complexity, protective membrane is also difficult for breaking, thereby has avoided the problem of the eyelet inwall of can not fitting completely easily causing while adopting plug protection.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the method for protecting workpiece eyelet when the surface treatment of embodiment of the present invention is protected workpiece 10 during for anodic oxidation, offers multiple eyelets 11 on workpiece 10.The eyelet 11 of embodiment of the present invention comprises irregular eyelet and threaded hole, and its longitudinal degree of depth is roughly 0.1-15 millimeter (mm), and its transverse width is roughly 0.9-10 mm.The coating that embodiment of the present invention adopts comprises resin, solvent and additive, and the surface tension of coating is less than or equal to 22 milli Newton/meter (mN/m), and the solid content of coating is less than or equal to 30%.Resin can be the resin of acid-alkali-corrosive-resisting, comprises fluorine resin, silica gel, silicon rubber, epoxy resin, acrylic resin, urethane or wherein one or more.The above-mentioned resin of enumerating generally can be made modification, makes the resin after modification contain fluorine functional group, hydrocarbon aliphatic functionality or organosilicon functional group, to reduce its surface tension.Solvent can be conventional organic solvent, as isoparaffin solvent, toluene, ethyl acetate, acetone, butanone etc.The composition that is appreciated that solvent there is no particular restriction, as long as can dissolve above-mentioned resin, and does not react with anodised reaction solution.Additive comprises in thinner, solidifying agent, initiator, sensitizer, adhesion promoter, dispersion agent, wetting agent, thickening material, defoamer or wherein one or more.Be appreciated that additive also can omit.
When the surface treatment of present embodiment, protect in the method for workpiece eyelet, first, allotment coating, makes the surface tension of coating be less than or equal to 22mN/m; Then, coating is evenly coated the inwall of eyelet 11; Finally, coating material solidified, thus form the protective membrane 30 that covers eyelet 11 inwalls.When coating material solidified, according to resiniferous type in coating, can adopt photocuring or thermofixation.In embodiment of the present invention, the thickness of protective membrane 30 be 0.1-5 micron (μ m), as 1 μ m, 2 μ m or 3 μ m.Coating process can adopt the modes such as infiltration, brushing, spraying or showering.The thickness of protective membrane 30 can regulate by the solid content of coating.
Because the surface tension of coating is less than or equal to 22mN/m; coating easily forms complete protective membrane 30 at the inwall of eyelet 11; even eyelet 11 complex structures, protective membrane 30 is also difficult for breaking, thereby has avoided adopting plug to protect the problem of the eyelet inwall of can not fitting completely easily causing.Even when eyelet 11 hour, protective membrane 30 also can not depart from from eyelet 11 inwalls, the problem of having avoided the plug easily having caused while adopting plug protection to come off.Meanwhile, because protective membrane 30 thickness are less, within the scope of the size deviation of eyelet 11, after surface treatment without removal, thereby simplified Production Flow Chart, reduced production cost.
Fig. 2 has enumerated 3 embodiment and 1 coating that comparative example adopts to illustrate embodiment of the present invention.
Be appreciated that, in the time that workpiece 10 carries out application, baking vanish or sandblast etc. and does not relate to the surface treatment of acid-base reaction liquid, resin can be also the resin of non-acid-alkali-corrosive-resisting, be that resin is selected corresponding to concrete surface treatment method, only has its resistance to corresponding surface treatment, as while electroplating, as long as the resistance to plating of resin.
Be appreciated that those skilled in the art also can do other and change in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
