Abstract
A surface treatment covering method includes the steps of providing an injector with filler including resin which is tolerant to surface treatment; injecting the filler into a pore of a workpiece with the injector to fully fill the pore, with part of the filler, protruding out of the pore of the workpiece; solidifying the filler to form a protective plug for protecting the pore. The pore is filled with the filler by means of injecting to form the protective plug, the pore even in an irregular shape or complex structure can be fully filled with the filler, and the formed protective plug fits the inner wall of the pore accordingly.
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 surface of the work is processed, as application, baking vanish, 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 more difficult eyelet that stops up completely of protection gum cover, 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: the syringe that filler is housed is provided, and this filler comprises resin, the resistance to surface treatment of this resin; This filler is injected workpiece eyelet by this syringe, and this filler is full of and outstanding this workpiece eyelet of part; Solidify this filler, to form the protection plug of this eyelet of protection.
Owing to adopting injection mode that filler is filled to eyelet to form protection plug, even if the out-of-shape of eyelet or structure are more complicated, filler also can be full of eyelet completely, makes the inwall of the protection plug laminating eyelet forming.

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Refer to 1, when the surface treatment masking methods of embodiment of the present invention is used for anodic oxidation, protect workpiece 10, on workpiece 10, offer multiple eyelets 11.The eyelet 11 of embodiment of the present invention comprises irregular eyelet and screwed hole.The filler that the method for the protection eyelet of embodiment of the present invention adopts comprises resin, solvent and additive.Resin can be the resin of general acid and alkali-resistance, can comprise SIS/SEBS (Styrene-Ethylene-Butylene-Styrene, SEBS), styrene-butadiene-styrene (Styrene-Butylene-Styrene, SBS), amorphous state alpha olefin copolymer (Amorphous poly alpha olefin, APAO), silicon rubber (silicon rubber), epoxy resin, polyurethane or wherein one or more.Solvent can be conventional organic solvent, can comprise isoparaffin solvent, toluene, ethyl acetate, acetone, butanone or wherein one or more.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 reactant liquor.Additive can comprise diluent, curing agent, initiator, sensitizer, adhesion promoter, dispersant, wetting agent, thickener, defoamer or wherein one or more.Be appreciated that when above-mentioned resin is ickiness, also can omit solvent and additive.
See also Fig. 2 and Fig. 3, the comprising the following steps at surface treatment masking methods of present embodiment:
In step S101, provide the syringe 30 that filler is housed.
In step S102, filler is injected eyelet 11 by syringe 30, and filler is full of and the outstanding eyelet 11 of part.
In step S103, to solidify filler, thereby form the protection plug 50 of protection eyelet 11, and protect the percentage elongation of plug 50 to be more than or equal to 250%, its tensile strength is more than or equal to 7MPa.
Be appreciated that while solidifying filler, can adopt photocuring or heat cure according to the concrete composition of resin.
After anode is processed, one end of drawing protection plug 50 outstanding eyelets 11, thus will protect plug 50 to separate with workpiece 10.
Thereby form protection plug 50 owing to adopting injection mode that filler is filled to eyelet 11; even if out-of-shape or the structure of eyelet 11 are more complicated; filler also can be full of eyelet 11 completely; the fit inwall of eyelet 11 of the protection plug 50 that makes to form, can avoid the problem of the eyelet inwall of can not fitting completely easily causing while directly adopting plug protection.Because the percentage elongation of protection plug 50 is more than or equal to 250%, its tensile strength is more than or equal to 7MPa, anode will protect plug 50 to separate with workpiece 10 after processing time, protection plug 50 had both easily been pulled out and be also difficult for rupturing in the time of drawing.In addition, owing to adopting injection mode, easily realize automated job, thereby enhance productivity.
Refer to Fig. 4, wherein enumerate 4 embodiment 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, as long as 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.
