Abstract
The invention relates to a protecting film and a production method of the protecting film. The production method of the negative film protecting film comprises the following steps of: (1) gluing, coating a layer of glue on a PET (polyethylene glycol terephthalate) releasing film; (2) baking, baking the glued PET releasing film; (3) bonding, bonding the baked PET releasing film with the other transparent PET thin films; and (4) coating silicon, coating a layer of silicon oil on the upper surface of one side of the transparent PET thin film on the bonded product formed in the step (3). The negative film protecting film comprises the PET releasing film, the gluing layer, the PET thin film and the silicon oil layer; and the gluing layer is arranged between the inner surface of the PET thin film and the inner surface of the PET releasing film, and the silicon oil layer is coated at the outer surface of the PET thin film. The invention has the benefit effects that the high-light transmittance PET film is taken as a base material, and the acrylic ester adhesives are subsidiarily used, so that the protecting film is good in light transmittance, low in haze, free from stains on the surface, good in stickiness, and hard to deglue.
Description
[technical field]
The present invention relates to a kind of diaphragm and preparation method thereof.
[background technology]
Egative film is because the physicochemical property of its surfacing is unstable; Contact cause such as easy damaged and need be on its surface with the supporting use of layer protecting film; It is low that egative film diaphragm of the prior art mainly contains transmittance; Deficiencies such as there is stain in the surface, and mist degree is higher and be prone to come unstuck all can produce remarkable harmful effect to the use of egative film.
[summary of the invention]
The objective of the invention is to propose a kind of transmittance height, low, the spotless egative film diaphragm of mist degree.
The present invention realizes through following technical scheme:
The method for making of said egative film diaphragm comprises the steps:
(1) gluing, coating one deck glue above the PET mould release membrance;
(2) baking is carried out baking processing with PET mould release membrance behind the above-mentioned gluing;
(3) fit, the PET mould release membrance after the above-mentioned baking and another clear PET is film adhered;
(4) be coated with silicon, the clear PET film one side upper surface coating one deck silicone oil on the applying article of in step (3), accomplishing.
Further, said PET mould release membrance thickness is 23 microns to 25 microns, and said clear PET film thickness is 6 microns.
Further, use the esters of acrylic acid adhesive during gluing in the step (1), said esters of acrylic acid adhesive thickness is 2 microns to 6 microns;
Further, said silicone oil silicon content is about 2%.
Further, the baking in the step (2) is meant the PET mould release membrance behind the gluing is at the uniform velocity passed through baking oven with 35 meters/minute speed.
Said egative film diaphragm comprises PET mould release membrance, rubberised layer, PET film and silicon layer; Said rubberised layer is between the inside surface of said PET film and PET mould release membrance, and said silicon layer is coated with said PET film outside surface.
Further, said PET mould release membrance thickness is 23 microns to 25 microns, and said clear PET film thickness is 6 microns.
Further, the main esters of acrylic acid adhesive that uses in the said rubberised layer, its thickness is 2 microns to 6 microns;
Further, said silicon layer silicon content is about 2%.
Beneficial effect of the present invention is: adopting the PET film of high transmission rate is base material, is aided with the esters of acrylic acid adhesive, and transmittance is good, surperficial inviolateness, and viscosity is good, is difficult for coming unstuck.
