Abstract

The invention discloses a novel pull ring material suitable for laser processing and a preparation method of the novel pull ring material. Specific inner-layer coating and outer-layer coating are adopted, through reasonable matching, the inner-layer coating can withstand the high temperature during laser processing, thus an aluminum substrate is prevented from being damaged during laser, the aluminum substrate is protected, and lowering of the yield strength and the tensile strength of the aluminum substrate is avoided; the novel pull ring material prepared by the preparation method is suitable for laser processing, has excellent laser processing performance, and meanwhile is decorative, different colors can be chosen according to packages so as to meet different needs of customers, thus the personality of the product is reflected, and a two-dimensional code and characters can be arranged on the product in a laser mode so that an anti-counterfeiting function can be achieved; and in addition, the process is simple, the production cost is low, pollution to the environment can be effectively lowered, the number of coating and printing times is decreased, VOCS emission is reduced, andgood economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the field of novel composite materials, and in particular relates to a novel 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,...
