Abstract
The invention discloses a manufacturing method of a laser positioning film with lower pollution, which comprises the following steps: firstly, selecting a PET film as a base material, attaching a layer of aluminum film on the PET film, and then coating varnish paint on the surface of the aluminum film; secondly, carrying out light irradiation on the PET film to solidify the varnish coating on the surface; step three, the PET film is pressed on the front side and the back side simultaneously, and the pressure intensity is 150N/cm 3 The method comprises the steps of carrying out a first treatment on the surface of the Step four, conveying the PET film into an oven for heating after pressing; and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film. The varnish coating is coated on the aluminum film, so that harmful substances such as acetone, butanone and the like in the PET film cannot escape, and the harm to human bodies is reduced.
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 with lower pollution.
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 molding mode, is extremely susceptible to high temperature in the production process, and is subjected to transverse and longitudinal stretching deformation, in addition, the thickness of a material coating is thinner, embossing is unclear due to insufficient thickness of the coating, and if the thickness of the coating is simply increased, the coating is not feasible due to thermal energy embossing, and the thicker the coating is, the greater the risk that the coating is heated and falls off in the molding embossing process.
Disclosure of Invention
In order to solve the problems in the related art, the application provides a manufacturing method of a laser positioning film with lower pollution, which can improve the coating strength.
The technical proposal is as follows:
the manufacturing method of the laser positioning film with lower pollution comprises the following steps:
firstly, selecting a PET film as a base material, attaching a layer of aluminum film on the PET film, and then coating varnish paint on the surface of the aluminum film;
secondly, carrying out light irradiation on the PET film to solidify the varnish coating on the surface;
step three, the PET film is pressed on the front side and the back side simultaneously, and the pressure intensity is 150N/cm 3 ；
Step four, conveying the PET film into an oven for heating after pressing;
and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film.
The varnish coating is coated on the aluminum film, so that harmful substances such as acetone, butanone and the like in the PET film cannot escape, and the harm to human bodies is reduced.
Further, in the first step, the raw materials of the gloss oil coating include ethyl acetate, ethanol, propylene glycol and acrylic ester.
Further, the weight ratio of ethyl acetate, butyl acetate, propylene glycol and acrylic ester is 4:6:1:4.
further, the raw materials are mixed and heated for 15-30min, and the heating mode is electric heating.
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.
