Inkpad and preparation method thereof

Abstract

The invention belongs to the technical field of inkpad preparation, and particularly relates to an inkpad and a preparation method thereof. The inkpad is prepared from 50-80% of ultraviolet curing resin, 10-50% of reactive diluent, 2.0-5.0% of photoinitiator, 0.8-2.0% of a color developer, 0.5-2.0% of fluorescent rare earth metal complex, and 2.0-8.0% of assistant. The preparation method comprises: A, preparing a blank base; B, preparing the fluorescent rare earth metal complex; and C, preparing the inkpad. Compared with the prior art, the above scheme realizes the quick-drying performance ofthe inkpad by using ultraviolet light for triggering the rapid polymerization and solidification characteristics of organic molecular monomers, and special rare earth composite fluorescent anti-counterfeiting molecules are added to realize the lifetime anti-counterfeiting function of the inkpad. The prepared inkpad is convenient to use and fast in solidification speed, and can be solidified by irradiation with an ultraviolet lamp, the operation is convenient, and the long waiting time for imprinting solidification after using traditional inkpads is avoided; the addition of the fluorescent rareearth complex also facilitates the identification of authenticity of documents.

Description

technical field [0001] The invention belongs to the technical field of ink pad preparation, and in particular relates to an ink pad and a preparation method thereof. Background technique [0002] Seal imprinting is widely used in all aspects of life and work. For example, for calligraphy lovers, every time a piece of work is completed, a famous seal needs to be affixed. However, after each stamp is stamped, there will be a problem that the imprint will dry slowly. It is necessary to speed up the drying of the ink pad by blowing air, wiping with a paper towel, etc. A little carelessness in the process will damage the calligraphy works; another example is that the school issues tens of thousands of admission notices to new students each year, and each notice must be stamped with the official seal of the school and the signature of the principal. Because the ink pad blots dry slowly, in order to prevent the blots from sticking to each other and causing the blots to be blurred ...

For example, for calligraphy lovers, every time a piece of work is completed, a famous seal needs to be affixed. However, after each stamp is stamped, there will be a problem that the imprint will dry slowly. It is necessary to speed up the drying of the ink pad by blowing air, wiping with a paper towel, etc. A little carelessness in the process will damage the calligraphy works; another example is that the school issues tens of thousands of admission notices to new students each year, and each notice must be stamped with the official seal of the school and the signature of the principal. Because the ink pad blots dry slowly, in order to prevent the blots from sticking to each other and causing the blots to be blurred and invalidated, the admission notices after stamping can only be placed all over the floor, and it will take a day or two to dry and put them away.
