Abstract
The invention discloses a fabrication process of a multilayer PET (Polyethylene Terephthalate) protective film, comprising the following steps of: firstly, carrying out corona treatment on one surface of a prepared PET film; secondly, coating gluewater on the corona surface of the PET film by using a coating machine, and then feeding the PET film coated with the gluewater into an oven; thirdly, directly winding the PET film taken out of the oven into a mother roll; fourthly, after encoding the wound mother roll, feeding the mother roll into a curing chamber for curing; and fifthly, feeding the cured mother roll into a multi-shaft laminating machine according to a first-in first-out principle for multi-layer lamination, wherein during lamination, one PET film coated with the gluewater, roasted by the oven and prepared in the step two is firstly tiled and laminated on the mother roll without air bubbles, the other PET film coated with the gluewater, roasted by the oven and prepared in the step two is laminated on the PET film without air bubbles, and then repeated lamination is carried out. The fabrication process of the multilayer PET film changes the traditional process, reduces the fabrication hour consumption when repeating the process, also reduces the waste of waste materials, lowers cost and improves product competitiveness.
Description
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 the 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, at 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;
In the 3rd step, the PET film that comes out from baking box, 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, carry out lamination coating, during applying at first will by second step make there is no bubble through the roasting good PET film tiling that scribbles glue of baking box and fit in described parent roll, again with another by second step make through the roasting good PET film bubble-free laminating that scribbles glue of baking box on described PET film, so repeat to fit.
Glue-spread is 30g/m in second step of the present invention
2
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.
Description of drawings
Fig. 1 is original single-layer PET diaphragm
Fig. 2 is the multilayer PET diaphragm that the present invention produces
Among the figure 1, the PET diaphragm; 2, glue; 3, release liners.
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, at 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;
In the 3rd step, the PET film that comes out from baking box, 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, carry out lamination coating, during applying at first will by second step make there is no bubble through the roasting good PET film tiling that scribbles glue of baking box and fit in described parent roll, again with another by second step make through the roasting good PET film bubble-free laminating that scribbles glue of baking box 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.
The multilayer PET diaphragm (as shown in Figure 2) that generates through above-mentioned steps also needs through die cutting technique the multilayer PET diaphragm that generates to be cut into the big or small PET diaphragm of needs.Substitute original single-layer PET diaphragm by this manufacture craft production multilayer PET diaphragm, not only save man-hour but also save 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 do anyly be equal to change or modify, all fall into the scope that this patent comprises.
Claims (2)
1. the manufacture craft of multilayer PET diaphragm is characterized in that, this technology may further comprise the steps:
The first step is a surface corona of ready PET film;
In second step, by a coating machine cementing, the described PET film that coats glue is sent into baking box at the corona surface of described PET film;
In the 3rd step, the PET film that comes out from baking box directly is 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, carry out lamination coating, during applying at first will by second step make there is no bubble through the roasting good PET film tiling that scribbles glue of baking box and fit in described parent roll, again with another by second step make through the roasting good PET film bubble-free laminating that scribbles glue of baking box on described PET film, so repeat to fit.
