Technical field
Patent of the present invention relates to a kind of acidproof protective membrane adhesive tape, specifically, is the acidproof protective membrane adhesive tape that a kind of PET and CPP Material cladding form.
Background technology
Present acidproof protective membrane is on the market to take pure PET as base material substantially, and when laminating OGS glass, attaching property is poor, easily causes edge section leaving certain gaps uncovered by the economic plan when acid etching, causes the complete glass strain point of etching in indentation, there, and frangible, condemnation factor is high.And by the material after compound by PET and CPP, aspect toughness, be greatly improved, it is good that the acidproof protective membrane adhesive tape of making attaches property, and after glass edge laminating, no acidic etching solution infiltrates, and etched edge is level and smooth, thereby improves the yield of OGS glass.Thereby quality and the reliability of product in the acid etch process of OGS glass, have greatly been improved.
Summary of the invention
Patent object of the present invention is to overcome now on the market acidproof protective membrane adhesive tape poor toughness, stickiness is poor, when OGS glass etching, and the deficiency of the problem such as yield is low, frangible and a kind of novel acidproof protective membrane adhesive tape that provides.
Patent of the present invention is achieved through the following technical solutions:
The present invention is a kind of acidproof protective membrane adhesive tape; comprise PET base material, acrylate glue water layer A, CPP base material, acrylate glue water layer B and release film; PET base material top is provided with acrylate glue water layer A; acrylate glue water layer A top is provided with described upper CPP base material; PET base material below is provided with acrylate glue water layer B; acrylate glue water layer B below is provided with release film; PET base material is bonding by acrylate glue water layer A and CPP base material; PET base material is compound as a whole by acrylate glue water layer A and CPP base material, and described PET base material is bonding by acrylate glue water layer B and release film.
As improving further, the thickness of PET base material of the present invention is 50 to 100 μ m.
As improving further, acrylate glue water layer A of the present invention is super sticky vinylformic acid glue, and super sticky vinylformic acid glue is compound as a whole by PET base material and CPP base material.
As improving further, the thickness of acrylate glue water layer A of the present invention is 2 to 10 μ m.
As improving further, CPP base material thickness of the present invention is 38 to 100 μ m.
As improving further, acrylate glue water layer B of the present invention is acidproof and low stripping force glue, and viscosity acidproof and low stripping force glue is the strippable degree of release film.
As improving further, acrylate glue water layer B of the present invention is hydrofluoric acid resistant and low stripping force glue, and the viscosity of hydrofluoric acid resistant and low stripping force glue is the strippable degree of release film.
As improving further, acrylate glue water layer B thickness of the present invention is 10 to 30 μ m.
As improving further, the thickness of release film of the present invention is 38 to 75 μ m.
Beneficial effect of the present invention is:
CPP material softness is good, but only uses CPP too soft, is not suitable for cross cutting and laminating; PET toughness of material is good, but only use PET material too hard, be not suitable for laminating, edge section has bubble point, cause in acid etching process local bad, the technical scheme of this patent is the effective combination to CPP and PET, and the selection of its thickness has also been done to special design and restriction, makes it to beam back its characteristic separately, impel toughness and the flexibility perfect adaptation of product, to realize the cooperation of die-cutting process and etch process, improve product yield, products obtained therefrom good toughness of the present invention, to attach performance better.
