High wear-resistant UV release agent coating applied to slipper transfer printing and preparation method thereof

Abstract

The invention provides a highly wear-resistant UV release agent coating applied to slipper transfer and a preparation method thereof. The coating comprises the following components in percentage by weight: 2-5% of an initiator body, 5-12% of a promoter, 20-40% of a reactive diluent, 20-40% of urethane acrylate, 10-30%of alkoxylated acrylate and 1-5% of a silane coupling agent. The UV release agentcoating prepared in the invention is high in curing degree and excellent in solubility, the absorption wavelength reaches 390nm, any organic solvent is not released in the curing process and in the prepred product, the needed amount of the cured ultraviolet energy is 50mj / cm<2> only, the curing time only needs 1-3 seconds, and the prepared coating is a high-efficiency, energy-saving and environmental-friendly photocuring release coating and can be widely applied to slipper transfer.

Description

technical field

[0001] The invention relates to the technical field of back coating coatings, in particular to a high wear-resistant UV release agent coating applied to slipper transfer printing and a preparation method thereof. Background technique

[0002] Different slipper materials generally require certain patterns to be printed on the surface. The possibility of printing directly on the slipper surface is very small. At present, it must be realized through the following process: OPP / CPP and other substrates are coated with a printable release agent. Various inks are printed on the mold, and then a layer of transfer glue is applied on the printing ink. After slitting, the printed pattern is transferred to the slippers under a certain temperature and pressure. Usually the release agent will stay on the slippers.

[0003] At present, the release agent used is usually acrylic resin material. This type of material can ensure printing performance and release function, but ca...
