Abstract

The invention provides a preparation method for a laser aluminized film, and solves the problems that the production technology for the laser aluminized film is complicated and it is not easy to control the coating uniformity in the prior art. The preparation method for the laser aluminized film comprises the steps that 1 a polyester (PET) base film is coated with a polythene (PE) film layer; 2 the PE film layer is coated with a laser layer, then laser mould pressing is conducted on the laser layer, and a mould pressing layer is formed; 3 the mould pressing layer is coated with tackiness agent, the coating weight is 1.5 g / m2, and the PET base film is peeled off through a peeling-off machine, so that a film base with the PE film layer, the laser layer and the mould pressing layer is obtained, and vacuum aluminizing is conducted on the PE film layer; and 4 an aluminized layer is coated with a protective layer. The coating material in the protective layer comprises, by weight, 13-24 parts of acrylic emulsion, 15-30 parts of styrene-acrylic emulsion, 25-35 parts of deionized water and 12-20 parts of isopropyl alcohol. According to the preparation method for the laser aluminized film, a one-time coating method is adopted, so that the coating weight in the whole process is controllable; in addition, the operation is simple, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a laser aluminized film. Background technique [0002] Aluminized film has been widely used in the packaging industry in the world since the 1980s. It has a strong metallic texture and bright color. It can be printed and colored. It has good reflection ability for infrared light and ultraviolet light and has temperature insulation, It is a new type of packaging material with the characteristics of oxygen barrier and light protection. Due to the low amount of aluminum used in aluminized products, low material cost, good flexibility, and degradable recycling, it has been widely used in the packaging and decoration of cigarettes, food, medicine, and trademarks. The production process of laser aluminized film on the market Generally, it is a transfer method, that is, to coat the PET film twice, and then carry out vacuum aluminum plating, and then a...
