Problems solved by technology

However, the current fluorescent inks cannot be used in the above-mentioned fields. The main reason is that the fluorescence intensity of the existing fluorescent inks under ultraviolet irradiation is not enough, which leads to the identification error of the photoelectric recognition machine on the production line of the existing bag making process, resulting in photoelectric tracking. Failed, unable to actually put into application

Abstract

The invention belongs to the field of fluorescent ink, and particularly discloses ink capable of realizing cursor invisibility and a preparation technology and application thereof. The ink is prepared from, by weight, 100 parts of deionized water, 40-60 parts of oligomeric PVA, 20-40 parts of polymeric PVA, 15-25 parts of fluorescent pigment, 10-30 parts of oxalic acid, 10-20 parts of cellulose, 8-16 parts of sodium alginate, 5-10 parts of coumarin, 5-8 parts of wear-resistant auxiliaries, and 2-4 parts of a defoaming agent. The ink capable of realizing cursor invisibility disclosed by the invention is low in harmful component content, high in fluorescence intensity, environment-friendly in preparation method and good in effect when being applied to the field of bag making.

Description

technical field [0001] The invention belongs to the field of fluorescent inks, and specifically discloses an ink for realizing invisible cursors, a preparation process and an application thereof. Background technique [0002] In the traditional factory bag making process, since the machine needs to determine the position through photoelectric induction, optical marks must be printed on the bag material to realize bag making, so as to make bags of various shapes. Therefore, there is usually a rectangular black cursor on the finished bag after traditional bag making, especially for the finished product delivered in coil, which affects the appearance of the finished bag. In order to solve this problem, there is a great need for a method to make the optical mark invisible to the naked eye under ordinary light, but it can be sensed by the photoelectric sensor of the machine on the bag making production line without affecting the work of the automatic bag making machine. So the e...
