Abstract
The invention discloses a method for processing a protective film and belongs to the technical field of surface protective film. The protective film consists of a substrate, a pressure-sensitive layer bonded on one side surface of the substrate, and a releasing layer bonded above the pressure-sensitive layer, wherein the pressure-sensitive layer has a floating-point structure or a latticed structure. The method has the advantages that due to the floating-point structure or the latticed structure of the pressure-sensitive layer bonded on the substrate, the protective film, when covered on the surface of a product, does not cause air bubbles and can fully demonstrate a bonding effect with the surface of the product; less procedures are required; and the protective film has excellent bonding effect with the surface of the product.
Description
Technical field
The invention belongs to surfacecti proteon membrane technology field, be specifically related to a kind of diaphragm, and relate to the processing method of this kind diaphragm.
Background technology
The purposes of diaphragm is very extensive, main but be applied to surfacecti proteon to LCDs, DVD, instrument and meter, diffusion sheet, LGP, reflector plate, plastic shell, five metals minute surface, refrigerator, air-conditioning, washing machine, nameplate, stainless steel, plastic-steel section bar, aluminium alloy, color steel, coated plate, glass and high-grade furniture etc. with being not limited to.
Before, the measure that people take the surface protection of the said goods was: with dustproof roller abrasive tumbling, shortcoming is can not ensure to clean effect; Dustproof roller abrasive tumbling injures product surface easily; Belong to the passive type protection, because trifle in the world etc. have been stained with and the surface of product, the friction of trifle in the world and product surface aggravation causes twice injury to product when abrasive tumbling.
Along with people product is lifted above for example and requirement of shelter harsh day by day of product surface; do not allow to enable front surface and speckle with trifle in the world at product; therefore adopt the surface that is attached at product by diaphragm shown in Figure 5 usually; diaphragm shown in Figure 5 comprises base material 1, varistor layer 2 and release layer 3; base material 1 adopts polyester film usually; varistor layer 2 is coated on a side surface of base material 1, and release layer 3 is compounded on the varistor layer 2.In the time will using, as long as remove the release layer 3 that is generally release liners, by means of making base material 1 attach to the surface of product as varistor layer 2 by pressure sensitive adhesive.Protection is implemented on surface to product.But; the diaphragm of said structure exists following technical problem: when using; removing after release layer 3 makes base material 1 adhere to product surface by means of varistor layer 2; often between base material and product surface, show the countless pores that are dispersed in distribution; yet; can not guarantee the effect that combines of diaphragm and product surface just because of the existence of pore, even can cause diaphragm to come off from product.From the mode of thinking of routine, a side surface of base material 1 evenly is coated with the varistor layer 2 of desired thickness, just can embody the effect that combines with product surface, and facts have proved that this mode of thinking can not prove effective.Reason is that the pore between base material 1 and the product surface can't eliminate; LCDs with processing mobile phone or computer is an example; because the existence of pore and/or bubble; diaphragm tends to occur failing comprehensive phenomenon that overlaps with the panel of LCDs; although when initially pasting diaphragm, show as coincidence; but in the manufacturing procedure in road, back, occur aforementioned circumstances usually, cause the LCDs defective product, because diaphragm need be combined in product surface when going out lotus with this series products enduringly.And a side surface of base material 1 is coated with varistor layer comprehensively and does not equably not only have desired combination effect with product, but also cause the consumption of raw materials of varistor layer 2 big, run counter to the spirit of the economizing economy of advocating at present.
Summary of the invention
Task of the present invention be to provide a kind of can fully ensure combine with product surface in conjunction with effect and can also reasonably save the diaphragm of the raw material that is used to constitute varistor layer.
Task of the present invention also is to provide a kind of processing method of diaphragm, and this method can ensure that diaphragm has aforesaid effect and technology is simple.
Task of the present invention is finished like this, and a kind of diaphragm is made of base material and the release layer that is combined in the varistor layer of base material one side surface and be combined on the varistor layer, and described varistor layer is floating-point shape or latticed structure.
A kind of diaphragm, by base material and the varistor layer of a side surface that is combined in base material and the adherent layer that is combined in the opposite side surface of base material, described varistor layer is floating-point shape or latticed structure.
In a specific embodiment of the present invention, the thickness of described base material is 8-150 μ m.
In another specific embodiment of the present invention, the material of described base material is polyethylene film, polyester film, polypropylene film or bidirectional stretching polypropylene film.
Go back in the specific embodiment of the present invention, the thickness of described varistor layer is 2-15 μ m, and the order number of described floating-point or grid is the 30-300 order.
In another specific embodiment of the present invention, the material of described varistor layer is oiliness acrylic acid or water soluble acrylic acid.
In another specific embodiment of the present invention, described adherent layer is 17-fluoro-decene base-3 a methoxy silane epithelium.
A kind of processing method of diaphragm, it may further comprise the steps:
A) choose qualified base material;
B) coating is earlier carried out sided corona treatment to the surface of base material, has glue spreader that floating-point shape or reticulate pattern construct with the surface more pressure-sensitive sizing material is applied to a side surface of base material, obtains the coated substrate that a side surface has the varistor layer of floating-point shape or reticulate pattern structure;
C) oven dry; the coated substrate that one side surface is had the varistor layer of floating-point shape or reticulate pattern structure is introduced the drying tunnel of coating machine; going out drying tunnel and after cooling release layer is being compound on the varistor layer, rolling obtains the diaphragm that is made of release layer, varistor layer and base material.
A kind of processing method of diaphragm, it may further comprise the steps:
A) choose qualified and base material be combined with adherent layer in advance at a side surface;
B) coating, earlier sided corona treatment is carried out on the surface of base material, the glue spreader that has a floating-point shape or reticulate pattern structure with the surface is applied to the opposite side surface of base material with pressure-sensitive sizing material again, obtains that a side has adherent layer and opposite side has the coated substrate of the varistor layer of floating-point shape or reticulate pattern structure;
C) oven dry is with step B) resulting coated substrate introduces the drying tunnel of coating machine, goes out rolling behind the drying tunnel, obtains the diaphragm that is made of varistor layer, adherent layer and base material.
More of the present invention and in specific embodiment, steps A) described in choose qualified base material be meant choose free of pinholes, do not have brilliant point, do not have scratch, non-wrinkled, transparency good and the base material of ideal flatness; The temperature of the drying tunnel of the coating machine step C) is a district 50-70 ℃, and two district 80-90 ℃, three district 80-110 ℃, four district 60-90 ℃, the gait of march of the base material that is coated with is 20-80m/min.
Therefore diaphragm disclosed in this invention after adhering on the product that needs surface protection, bubble can not occur because the structure that is incorporated into the varistor layer on the base material is become floating-point shape or latticed, can show the effect that combines with product surface fully; Process steps is few, can ensure that diaphragm has the excellent effect that combines with product surface.
