The manufacture craft of multilayer PET diaphragm
Technical field
The present invention relates to the manufacture craft of PET diaphragm, special design has the manufacture craft of the multilayer PET diaphragm of multilayer PET film.
Background technology
Former individual layer applying die-cutting process PET diaphragm covers release liners, and the scope of application is extensive in the market, is used in the protection working of plastics more and is fitted in notebook computer upper cover and multiple electronic goods.But single-layer PET diaphragm (as shown in Figure 1) has just slatterned as waste material with the release liners of covering that the PET film is fitted in use, and so producing single-layer PET diaphragm and waste material has consuming timely, so lacks a kind of manufacture craft of production multilayer PET diaphragm.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the present invention proposes a kind of manufacture craft of multilayer PET diaphragm, and this process exploitation purpose is to reduce consume in man-hour that iterative process makes and the waste that reduces waste material, and reaches and reduce cost, and promotes product competitiveness.
The present invention can be solved by the following technical programs:
The manufacture craft of multilayer PET diaphragm of the present invention, this technology may further comprise the steps:
The first step is a surface corona of ready PET film;
Second step, on the corona surface of described PET film by a coating machine cementing, the speed of service of this coating machine be 10-15 rice/minute, the described PET film that coats glue is sent into baking box;
The 3rd step, compound the PET film that comes out from baking box with yellow two single silicon release liners, and be wound into parent roll;
In the 4th step, behind the described parent roll coding after the rolling, send into the curing chamber slaking;
The 5th step, described parent roll after the slaking is sent into the multiaxis make-up machine by first in first out, carries out lamination coating, at first the tiling of PET film be there is no bubble during applying and fits in described parent roll, again with another PET film bubble-free laminating on described PET film, so repeat to fit.
The proportioning of glue of the present invention is: 100% acrylic glue: 1.5% bridging agent: 50% ethyl acetate.
Glue-spread is 30g/m2 in second step of the present invention.
The two single silicon release liners of described Huang have 50 gram off-type forces.
Owing to adopt above technical scheme, the manufacture craft of multilayer PET diaphragm of the present invention by repeating still coating technique, generates the multilayer PET diaphragm and replaces original single-layer PET diaphragm, not only saves resource but also save man-hour.

The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention:
The manufacture craft of multilayer PET diaphragm of the present invention, this technology may further comprise the steps:
The first step, a surface corona of ready PET film, this PET film is about 0.1 millimeters thick;
Second step, on the corona surface of described PET film by a coating machine cementing, the speed of service of this coating machine be 10-15 rice/minute, the described PET film that coats glue is sent into baking box;
The 3rd step, compound the PET film that comes out from baking box with yellow two single silicon release liners, and be wound into parent roll;
In the 4th step, behind the described parent roll coding after the rolling, send into the curing chamber slaking;
The 5th step, described parent roll after the slaking is sent into the multiaxis make-up machine by first in first out, carries out lamination coating, at first the tiling of PET film be there is no bubble during applying and fits in described parent roll, again with another PET film bubble-free laminating on described PET film, so repeat to fit.
The proportioning of the glue in above-mentioned second step of the present invention is: 100% acrylic glue: 1.5% bridging agent: 50% ethyl acetate.Joining glue is in proper order: put into A glue, 40% ethyl acetate, 1.5%CA, remaining 10% ethyl acetate successively, stirred for several minute obtains required glue.
Glue-spread is 30g/m2 in above-mentioned second step.
Yellow two single silicon release liners in above-mentioned the 3rd step are that 140g has 50 gram off-type forces.
The multilayer PET diaphragm (as shown in Figure 2) that generates through above-mentioned steps also needs the process die cutting technique multilayer PET diaphragm that generates to be cut into the PET diaphragm of needs size.Substitute original single-layer PET diaphragm by this manufacture craft production multilayer PET diaphragm, both having saved man-hour has the saving resource.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
