Abstract
The invention discloses a method for manufacturing a laser positioning film, which comprises the following steps: selecting a PET film as a base material, and coating a varnish coating on the surface of the PET film; step two, carrying out lamplight irradiation on the PET film to cure the gloss oil coating on the surface; step three, simultaneously pressing the front surface and the back surface of the PET film, wherein the pressure intensity is 150N/cm 3 (ii) a Step four, after pressing, feeding the PET film into an oven for heating; and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film. The density of the coating is improved by pressing the PET film, and the overall strength is improved.
Description
Technical Field
The invention belongs to the technical field of laser positioning films, and particularly relates to a manufacturing method of a laser positioning film.
Background
The laser positioning film is popular with consumers due to the fact that the laser positioning film has a three-dimensional effect, has a high-technology anti-counterfeiting function, is generally manufactured in a traditional laser mould pressing mode, a PET (polyethylene terephthalate) base film is extremely easily affected by high temperature in the production process, and therefore transverse and longitudinal stretching deformation is caused.
Disclosure of Invention
In order to solve the problems in the related art, the application provides a manufacturing method of a laser positioning film, which can improve the strength of a coating.
The technical scheme is as follows:
a manufacturing method of a laser positioning film comprises the following steps:
step one, selecting a PET film as a substrate, and coating a gloss oil coating on the surface of the PET film;
step two, carrying out lamplight irradiation on the PET film to cure the gloss oil coating on the surface;
step three, simultaneously pressing the front surface and the back surface of the PET film, wherein the pressure intensity is 150N/cm 3 ；
Step four, after pressing, feeding the PET film into an oven for heating;
and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film.
The density of the coating is improved by pressing the PET film, and the overall strength is improved.
Further, in the first step, the raw materials of the varnish include ethyl acetate, butyl acetate, propylene glycol and acrylate.
Further, the weight ratio of ethyl acetate, butyl acetate, propylene glycol and acrylate is 2:1:5:7.
further, mixing and heating the raw materials for 15-30min in an electric heating mode.
Further, in the first step, before the gloss oil paint is coated on the PET film, an aluminum film is attached to the PET film.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
