Description
Technical field
The invention belongs to procedure for processing technical field, it relates to a kind of novel edge banding processing procedure, it is specifically related in thin multilayer structure edge sealing process, comprise the coating technique using glue and the processing procedure by bestowing external power in addition edge sealing.
Background technology
For the manufacturing method thereof of multilayered structure, general processing procedure on the market has two kinds at present:
The first manufacturing method thereof is multilayer gluing stacking structure, its manufacturing method thereof used is one layer of glue, layer of material, if when needing to use sandwich, material and glue is then needed to intert staggered, every layer of material all must last layer glue, just produced supportive and the high product of pasting property, and so the multilayered structure of layer of material one layer of glue has several comparatively significantly shortcomings: (one), coated the glue of multilayer, and the thickness making the finished product can be partially thick, and limit the applicability of its product, (2), the all gluings of every layer of material top layer, glue can cause the obstruct between material layer, and the performance of intermediate sandwich material character is affected to some extent, and then reduce its product in the applicability of terminal, (3), if the functional material of the interlayer of centre is fluid, then cannot carry out the processing procedure of this kind gluing between material.
2nd kind is thin multilayer structure outer sealing edge laminating process technique (applicant's patent applied for, not yet open), for a kind of multilayer materials laminating edge banding technique, it may also be useful to the functional materials such as the plastics of different thickness, metal mutually intert heap repeatedly after in upper and lower layer i.e. band glue top layer, lower section and bottom the goods of complete outer sealing edge after laminating processing technology obtains processing. comparatively significantly shortcoming arranges as follows in detail: (one), owing to outer sealing edge all can exceed middle multilayer functional structure layer up and down when fitting, and then the rigidity that can cause product surface is not enough, especially show in the outer rim of edge sealing, (2), after product outer sealing edge, its product edge has a rigidity lower region, the problem in product operation can be caused during product so using in client terminal, (3), coated prod upper, lower floor is generally based on plastics, the slim base material of metal species is auxiliary, plastics easily cause surface fold in the middle of process of producing product and produce the problem of bad product.
It is more than the disappearance of current manufacturing method thereof, but then can overcome the above problem listed in detail by edge sealing process in the thin multilayer structure of this patent.
Summary of the invention
It is an object of the invention to overcome the problems referred to above, it is provided that a kind of utilize top layer or edge, functional top layer and the laminating of functional bottom edge realizing interior edge sealing, save glue material, simplify multilayered structure manufacture craft, make that multilayered structure corresponding product is thinner, strongthener performance, optimize in the middle of interlayer use material ranges, increase product surface rigidity, the thin multilayer structure laminating edge sealing process of preventing wrinkle to improve the quality of products.
In order to realize above-mentioned purpose, the technical solution adopted in the present invention is: edge sealing process in thin multilayer structure, comprises the steps:
1) 1a: some functional structure layers of fitting on the top layer base material of glue coating, Ruo Gangong
Functional bottom can be provided with bottom property structural sheet;
Or 1b: directly adopt the some merits of continuity being provided with functional top layer and functional bottom
Energy property structural sheet;

Functional middle layer 3 is protruded from owing to band glue top layer 1a and functional bottom 2 have edge respectively, the edge on top layer and the direct gluing, sealing in surperficial edge of functional bottom 2, close the multilayer functional structure of centre, and reach the effect of interior edge sealing and support, and these goods article construction after laminating edge sealing is complete, functional bottom 2 is generally metallic substance, so the supportive that product tool is certain, and on, lower surface outward appearance not easily folds, product structure is decreased the thickness of one layer of bottom compared to outer sealing edge coating technique and reduces the edge area that outer sealing edge coating technique likely folds.
Processing procedure one key step is:
(1) fit on the top layer base material of glue coating some functional structure layers.
(2) stamp process is done for the some functional structure layers being attached on the base material of continuity top layer.
(3) the some functional structure layers completed in stamp bring functional bottom into so that it is the object that reach interior edge sealing laminating bonded to each other with the top layer of band glue. It is noted that stamp process more some functional structure layers to be done after can also adding functional bottom.
The glue being coated with on the top layer base material of glue coating can be: pressure-sensing glue (PSA), conductive resin etc., wherein pressure-sensing glue (PSA) comprises rubber-type and resin type two class. Rubber-type can be divided into again natural rubber and synthetic rubber class; Resin type mainly comprises again acrylic acid or the like, silicone based and polyurethanes.
Some functional structure layers can comprise: metal: gold and silver, copper, iron, tin, aluminium etc.; Rubber or plastics: PE, PP, PET, PC, PU, TPU, silica gel, rubber etc.; Functional material: conducting strip, conducting strip, phase-transition material, graphite flake, anti-electromagnetic wave, antistatic material etc.
