Abstract
The invention discloses a coating method taking photographic developable coatings as a spraying covering jig. The photographic developable film-stripping coatings are used as the covering jig to cover the material surface, target coatings are sprayed on the whole surface, and after the film-stripping coatings are removed, a target pattern is left. The method is free from the restriction of the shape of a printing surface and the structure and position of a spraying pattern, and spraying of any pattern can be carried out on any irregular surface; after the photographic developable film-stripping coatings are covered with other coatings, the adhesive force difference exists and is utilized, and therefore synchronous removal of the photographic developable film-stripping coatings and the other coatings covering the photographic developable film-stripping coatings is achieved. The process is simple, and the economic benefits are large.
Description
Technical field
The invention belongs to external coating technical field, relate in particular to a kind of coating process of sensitization development coating as spray sheltering fixture of usining.
Background technology
For the application of material irregular surface (as curvature changes inner sunken face sharply, outer convex surface, compound curved surface) ad-hoc location or specific pattern, sometimes can take to block spraying or bat printing mode.What is called is blocked spraying not needing the part of coating process to cover up with tool, takes shading fixture after application away, leaves the specific pattern of ad-hoc location.So-called bat printing, develops special-purpose bat printing head, and the mode of the similar chapter of impressing prints to material surface pattern.Above-mentioned technique is subject to many condition restriction.For blocking spraying, tool corresponding to pattern be (otherwise cannot guarantee the position relationship between tool) continuously; Tool must be very good with material laminating (otherwise edge has seepage, pattern edge can be jagged), but due to the certainly existing property of product manufacturing tolerance, therefore laminating be difficult to accomplish very good; Meticulous especially pattern (as fade effect) is not developed shading fixture, thereby cannot spray.When cannot realizing, spray can consider that bat printing mode constructs hiding.For bat printing, limited by shape, special for shape, the face of undertaking the printing of that systematicness is poor, often can not develop respond well bat printing head; Can not use the occasion of pad-transfer printing ink (for example, to adhesive force require very high) this technique can not use completely.
In addition, develop special-purpose bat printing head and spray sheltering fixture, cost is often very high, is also difficult to once success, for few in batches order, all inadvisable in time and economic benefit.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of and usings sensitization development coating as the spraying method of spray sheltering fixture, is intended to solve traditional coating process and has the face shape of being undertaken the printing of, and pattern form restriction, process is complicated, cost is high, the problem of deficiency in economic performance.
The embodiment of the present invention is to realize like this, using sensitization development coating as the spraying method of spray sheltering fixture, and this processing method technological process comprises that usining sensitization can develop and can move back coating and after moving back film, leave target pattern as shading fixture, spraying, spray that target coating is carried out in whole surface;
Described using sensitization and can develop and can move back coating and refer to sensitization can be developed and can be moved back coating material surface is all covered as shading fixture, then the part that by sensitization visualization way, needs painting is installed to coating displays, expose material surface, do not need to be coated with the part install to coating and still by sensitization, can develop and can move back coating and cover;
Described application target coating is carried out in whole surface refer to application target coating is carried out in whole surface.
Described moving back leaves target pattern after film and refers to after target paint solidification, product is dropped into and moved back in film liquid, the effective ion (or molecule) that promotes to move back in film liquid in ultrasonic oscillation mode passes molecular gap in target paint film, can develop and can move back coating and react (thicker for target coating surface particularly compact or paint thickness with sensitization, move back that film liquid active ingredient still can not be through paint film surface under ultrasonic concussion, available laser or mechanical system break after osculum again row drop into move back film liquid), sensitization can be developed a little less than the adhesive force that can move back coating and material will become extremely, and target coating and material directly adhere to, it is many that adhesive force is eager to excel, with certain pressure, material surface is sprayed again, material surface is had sensitization to develop can to move back the part of coating remove in the lump together with the target coating covering on it, leave the target pattern of target location, realize the application of complex pattern on irregular curved surface.
Further, described using sensitization and can develop and can move back coating as the face shape of not undertaken the printing of in shading fixture, need the restriction of application this body structure of pattern and position, on irregular surface, can carry out the application of arbitrary graphic pattern arbitrarily, need not develop tool of a high price or bat printing head, only need to make the corresponding film and just can complete, cost is low.
Further, described carries out in sensitization, can developing and can moving back coating by the rear construction of other coating coverings in application target coating to whole surface, produce and utilize the difference of adhesive force, sensitization can be developed and can be moved back subsidiary other coating that cover top of coating and synchronously remove.
Provided by the inventionly using sensitization development coating as the coating process of spray sheltering fixture, the face shape of not undertaken the printing of, needs the restriction of application this body structure of pattern and position, can carry out the application of arbitrary graphic pattern arbitrarily on irregular surface; Need not develop tool of a high price or bat printing head, only need to make the corresponding film and just can complete, reduce cost low; Sensitization can develop can move back coating by other coating, covered after construction, produce and utilize the difference of adhesive force, realized sensitization and can develop and can move back the subsidiary synchronous removing that covers other coating on it of coating.Using sensitization development coating as the coating process of spray sheltering fixture do not need to develop special-purpose bat printing head and tool, process is simple, cost is low, economic well-being of workers and staff is large.
