Abstract
The utility model provides a low shrink polyester protection film that ITOFILM is high temperature resistant which characterized in that: it includes two -way stretch polyester film layer and release film layer, and is compound through functional bond line between the two, the two -way stretch polyester film layer for preheating shrink processing type, the shrinkage factor is 0.3% -0.5%, the high glue molecule adhesive of functional bond line for having added high functional curing agent and coupling agent. The beneficial effects of the utility model are that: 1 the utility model has the advantages of simple structure, equipment convenience, low in production cost, market competition is strong. 2, improve the shrinkage degree of ITO FILM polyester protection film, let its shrinkage factor follow 1% and drop to 0.3%, let the protection film possess good high temperature resistance ability simultaneously, preheating the appearance of avoiding other quality problems when the shrink in -process protects ITO FILM not influenced to fall to the defective rate.
Description
Technical field
This utility model relates to a kind of protecting film, specifically a kind of high temperature resistant low shrinkage polyester protecting film of ITOFILM.
Background technology
With the development of thin film application material, there is due to ITOFILM the characteristics such as good light transmission, electric conductivity etching property so that it is the application in every profession and trade is more and more extensive, and the application in particularly in electronics industry, such as electric touch screen, kinds of displays part etc.
ITOFILM is applied in electronics industry processing procedure; generally first coiled material ITOFILM is cut into sheet material; it is then passed through 30 minutes preheating shrink process of 150 DEG C of high temperature; and this process needs with using a polyester protecting film to carry out surface protection; but at present most of polyester protecting film on the market is after 150 DEG C of high temperature 30 minutes; shrinking due to film shrunk and glue creep causes ITOFILM tilting Texturized; even there is glue residual contamination ITOFILM surface, it is therefore necessary to existing ITOFILM protecting film is improved further.
Utility model content
The purpose of this utility model is the shortcoming in order to overcome prior art to exist; a kind of simple in construction is provided; easy to use; production cost is low; structural approach is novel, it is possible to avoid existing protecting film to occur the high temperature resistant low shrinkage polyester protecting film of a kind of ITOFILM of deformation, cull problem in thermal contraction processing procedure.
This utility model purpose realizes with the following methods: a kind of high temperature resistant low shrinkage polyester protecting film of ITOFILM; it is characterized in that: it includes biaxially oriented laminated polyester film and release film layer; between the two by functional adhesive layer compound; described biaxially oriented laminated polyester film is preheating shrink process type; shrinkage factor is 0.3%-0.5%, and functional adhesive layer is the high glue molecular adhesion agent of firming agent and the coupling agent that with the addition of high official energy.
Described release film layer is PET material, and its surface-coated has silicon coating.
Described release film layer thickness is 40 μm-180 μm.
Described functional bondline thickness is 0.06 μm-0.4 μm.
Described functional adhesive layer is acrylic resin.
The beneficial effects of the utility model are: 1, this utility model there is simple in construction, easy to assembly, the advantages such as production cost is low, and the market competitiveness is strong. 2, the shrinkage degree of ITOFILM polyester protecting film is improved; its shrinkage factor is allowed to drop to 0.3% from 1%; allowing protecting film possess excellent resistance to elevated temperatures, the protection impregnable appearance simultaneously avoiding other quality problems of ITOFILM in preheating contraction process, thus dropping to fraction defective simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural perspective.
Fig. 2 is this utility model structure sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model made concrete further instruction. A kind of high temperature resistant low shrinkage polyester protecting film of ITOFILM; it is characterized in that: it includes biaxially oriented laminated polyester film 1 and release film layer 3; between the two by functional adhesive layer 2 compound; described biaxially oriented laminated polyester film 1 is preheating shrink process type; shrinkage factor is 0.3%-0.5%, and functional adhesive layer 2 is the high glue molecular adhesion agent of firming agent and the coupling agent that with the addition of high official energy.
Described release film layer 3 is PET material, and its surface-coated has silicon coating.
Described release film layer 3 thickness is 40 μm-180 μm.
Described functional adhesive layer 2 thickness is 0.06 μm-0.4 μm.
Described functional adhesive layer 2 is acrylic resin.
Operation principle: use the mylar that shrinkage factor is less, coats functional adhesive to allow protecting film thermal contraction performance more preferably after high temperature preheating shrinks, and selects biaxially oriented polyester film; For making binding agent have heat-resisting quantity and low creep properties characteristic, select the firming agent of high official energy and add coupling agent to improve glue molecular weight, strengthening cohesiveness, thus improving the resistance to elevated temperatures of glue and reducing its creep properties. The beneficial effects of the utility model are; improve the shrinkage degree of ITOFILM polyester protecting film; its shrinkage factor is allowed to drop to 0.3% from 1%; allow protecting film possess excellent resistance to elevated temperatures simultaneously; the protection impregnable appearance simultaneously avoiding other quality problems of ITOFILM in preheating contraction process, thus dropping to fraction defective.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.
