Abstract

The invention provides a method for detecting water-resistant ultraviolet (UV) snowflake printing ink. The detection method comprises the following steps: preheating a UV light curing machine, adjusting the operating speed of the UV light curing machine, and adjusting energy of a UV lamp tube; uniformly scraping the prepared snowflake printing ink on body paper through a scraper; curing the printed snowflake printing ink in the preheated UV light curing machine, wherein the cured printing ink needs to present a snowflake effect and is cooled; fully absorbing the moisture by using a towel, taking out the towel and wringing to be dry; uniformly covering the wringed towel on the cured snowflake printing ink, timing while covering, testing in several periods of time, and dividing the test results according to the standard. According to the method for testing the water-resistant UV snowflake printing ink, fewer testing tools are used, the testing steps are simple and easy to operate, the test result is accurate, and the method is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of chemical polymer materials, in particular to a detection method for water-resistant UV snowflake ink. Background technique [0002] Because UV snowflake ink can form a snowflake-like transparent three-dimensional decorative effect after curing, it has the characteristics of good hand feeling, soft luster, strong three-dimensional effect, and fine patterns. It is widely used in tobacco and alcohol, moon cakes, tea, cosmetics and other high-end gifts. Packaging and Printing. At present, the outer packages of tobacco, alcohol, moon cakes, cosmetics and other products are mostly printed and mounted on gold and silver cardboard and laser cardboard, while paper substrates are prone to air absorption and mounting glue in the actual working environment and subsequent mounting process. Damp due to the moisture in it. Ordinary UV snowflake ink has poor water resistance, and it is prone to decrease in adhesion on ...
