Abstract

The invention discloses a ring-pull material suitable for laser processing and a preparation method thereof. Specific inner coatings and outer coatings are adopted, and through a reasonable ratio, the inner coating can withstand high temperatures during laser processing. , prevent damage to the aluminum base material during laser, protect the aluminum base material, and avoid the decrease of the yield strength and tensile strength of the aluminum base material; the pull ring material prepared by the present invention is suitable for laser processing and has excellent Laser processing performance; at the same time, it is decorative, and different colors can be selected according to the packaging to meet the different needs of customers and reflect the individuality of the product. It can have anti-counterfeiting functions by lasering two-dimensional codes and characters on the product of the present invention; in addition, the process of the present invention Simple, low production cost, can effectively reduce environmental pollution, reduce the number of times of coating and printing, reduce VOCS emissions, and have good economic and social benefits.

Description

technical field [0001] The invention belongs to the field of novel composite materials, and in particular relates to a pull ring material suitable for laser processing and a preparation method thereof. Background technique [0002] The traditional ring pull material takes on the function of opening the can after being assembled by a combination machine, and generally does not have the technology that can withstand laser. At the same time, the traditional pull-ring material uses ordinary organic paint with a single color; the traditional pull-ring material cannot be processed by laser due to the constraints of the production process and the characteristics of the paint. If the processing is forced, the pattern or character after laser will be blurred, and The coating peeled off when it was processed into a pull ring. [0003] At present, there is a technology for processing laser film on one side of the substrate, but for double-sided laser, if the control is not good, when ...
