Abstract
The invention discloses a product protecting layer, which comprises a base material arranged on the surface of a product and a repair layer arranged on the surface of the base material, wherein the base material is made of polyethylene terephthalate (PET), and the thickness of the base material is 0.125 millimeter; the repair layer is made of epoxy resin, and the thickness of the repair layer is 3 to 4 microns; an oil layer is arranged between the base material and the product, and the thickness of the ink layer is 2 to 3 microns; and a PET protective film with thickness of 0.03 millimeter is arranged on the surface of the repair layer. The invention also discloses a processing technology of the protecting layer. The processing technology comprises the following steps of: a) pressing the base material; b) coating adhesive on double sides of the base material; c) covering the repair layer on the surface of the base material, and spreading the PET protective film with thickness of 0.03 millimeter on the surface of the repair layer; and d) sequentially finishing printing, forming, die cutting and injection molding by adopting an internal mold labeling (IML) process. When the protecting layer produced by adopting the technology is subjected to light mechanical scratch of the surface, the protecting layer can finish self-healing in short time (0.5 to 1 second), so that the problem that the surface of an IML highlight product is easily scratched is solved.
Description
Technical field
The present invention relates to the product protection layer on a kind of IML of being used for product, and the processing technology of this product protection layer.
Background technology
IML (In-Mold Label) claim decoration technique inside mold again; Be that a kind of diaphragm that will print pattern is put into metal die; The resin of shaping usefulness injected in the metal pattern engages, make and print that figuratum diaphragm and resin-shaped are integral and the method that is solidified into finished product with diaphragm.
Because will there be stretching the side of IML product, thus require cementation zone to have good draftability, but draftability contradicts with the hardness (product scratch resistance coefficient) of product surface hardened layer again, product surface hardness high (damage resistant is good), and then the side draftability is poor; The side draftability is good, then product surface hardness low (scratch resistance is poor).
How to guarantee that high stretching in side and damage resistant coexistence become the maximum technical bottleneck of IML industry.
Summary of the invention
The purpose of this invention is to provide a kind of protective layer that has high stretching and damage resistant concurrently.
The technical solution adopted for the present invention to solve the technical problems is: a kind of product protection layer comprises the base material of being located at product surface and the repair layer of being located at substrate surface.
Be provided with ink lay between said base material and the product.
The material of said base material is PET.
The thickness of said base material is 0.125mm.
The thickness of said ink lay is 2-3 μ m.
The material of said repair layer is an epoxy resin.
The thickness of said repair layer is 3-4 μ m.
Said repair layer surface is provided with the PET diaphragm that a layer thickness is 0.03mm.
Another object of the present invention is to provide a kind of processing technology of above-mentioned protective layer.
The technical solution adopted for the present invention to solve the technical problems is: a kind of processing technology of protective layer comprises the steps: a), the base material pressing; B), base material double spread bonding agent; C), substrate surface covers repair layer; D), adopt IML technology to accomplish printing, shaping, die-cut and injection moulding successively.
Further, also be included in the step that the thick PET diaphragm of one deck 0.03mm is laid on the repair layer surface.
The invention has the beneficial effects as follows: the product protection layer that adopts this explained hereafter can be accomplished oneself's healing at short notice when running into surperficial slight mechanical the scuffing, solved the problem of the easy scuffing of the high light product surface of IML.
Description of drawings
Fig. 1 is the cutaway view of product protection layer of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
With reference to shown in Figure 1; A kind of product protection layer; Comprise the base material 3 of being located at product 1 surface and the repair layer 4 of being located at base material 3 surfaces; The material of base material 3 is PET, and thickness is 0.125mm, and the material of repair layer 4 is an epoxy resin; Thickness is 3-4 μ m; Be provided with ink lay 2 between base material 3 and the product 1, the thickness of ink lay 2 is 2-3 μ m, and repair layer 4 surfaces are provided with the PET diaphragm 5 that a layer thickness is 0.03mm.
A kind of processing technology of protective layer comprises the steps: a), base material 3 pressings; B), base material 3 double spread bonding agents; C), base material 3 surfaces cover repair layer 4, the thick PET diaphragm 5 of one deck 0.03mm is laid on repair layer 4 surfaces; D), adopt IML technology to accomplish printing, shaping, die-cut and injection moulding successively.
The protective layer that adopts this explained hereafter can be accomplished oneself's healing in the short time (0.5-1s) when running into surperficial slight mechanical the scuffing, solved the problem of the easy scuffing of the high light product surface of IML.
The foregoing description is illustrative principle of the present invention and effect thereof only; And the embodiment of part utilization, for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; Can also make some distortion and improvement, these all belong to protection scope of the present invention.
