Problems solved by technology

[0003] At present, in the final drying step of the production of water transfer stickers, baking drying or natural drying is usually used. The above two methods take a long time, requiring 3 to 6 hours, and in the existing solvent-based tearable film The solid content is about 40%. During the drying process, about 60% of the organic solvent will volatilize into the air. While causing serious air pollution, it will also cause certain physical injuries to the workers in the production workshop. In addition, traditional drying If the time is too long, it will cause damage to the product due to uncontrollable factors (such as dust, moisture, etc.) during the drying process, resulting in an increase in the product scrap rate during the production process

Abstract

The invention discloses a water transfer printing sticker and a preparation method thereof. The water transfer printing sticker is prepared from special water transfer paper, a pattern coating and a tear-off film layer, wherein a tear-off film is prepared from the following components in percentage by mass: 60 to 70 percent of a photocuring material, 3 to 6 percent of a photosensitizer, 20 to 30 percent of an active monomer and 3 to 7 percent of an assistant. According to the water transfer printing sticker disclosed by the invention, the tear-off film can be cured instantly through LED lightor UV light, instantaneous drying of the water transfer sticker is realized and products can be instantly packed, so that the production efficiency is greatly improved; and moreover, the rejection rate of the products is reduced.

Description

technical field [0001] The invention belongs to the technical field of making water transfer printing stickers, and in particular relates to a water transfer printing sticker that can be cured and dried instantly by light and a preparation method thereof. Background technique [0002] Water transfer stickers, that is, stickers that can only be used after soaking in water. It uses water as a carrier to separate the pattern from the backing paper and then transfer it to the substrate, so as to realize indirect printing. It is a brand-new transfer printing technology; it can be applied to glass, ceramic stickers, sports equipment, handicrafts, toys, plastic shells of thermos cups And other products, the principle is to print a tear-off film on the water-transfer special paper printed with a pattern, after drying it, transfer the pattern to the product by water transfer (that is, soaking in water), drain the water, and after the pattern is dry, The tearable film is separated ma...
