Water-based environment-friendly transfer paint with high smoothness on transfer layer surface and preparation method thereof

Abstract

The invention provides a water-based environment-friendly transfer paint with high smoothness on a transfer layer surface. The paint comprises the following components in parts by weight: 15-20 parts of water-based polyurethane, 18-30 parts of organosilicon modified acrylic resin, 5-8 parts of water-soluble silica sol, 10-13 parts of hand feeling resin, 0.5-1 part of silane coupling agent, 0.5-1 parts of fuzz powder, 0.1-0.2 part of leveling agent, 0.05-0.15 part of wetting agent, 0.08-0.15 part of defoaming agent and 30-60 parts of solvent. The paint overcomes the phenomenon that the smooth assistant always transfers to the surface layer (gas-liquid surface); the organosilicon modified acrylic resin and water-soluble silica sol added into the main body resin enhance the smoothness of the transfer layer surface, thereby developing the water-based transfer paint with high smoothness on the transfer layer; and the paint can be directly used for subsequent offset printing, and is economical and environment-friendly.

Description

technical field [0001] The invention relates to a water-based environment-friendly transfer paint with high slipperiness on the surface of a transfer layer and a preparation method. Background technique [0002] The general process of the transfer process in the cigarette pack industry is that the transfer coating is first coated on the PET film, and then the transfer coating is bonded to the substrate through an adhesive, and finally the PET film is peeled off, and the surface of the transfer layer is then subjected to subsequent offset printing. Since it is necessary to avoid the transfer coating being scratched by the rubber roller during the offset printing process and the phenomenon of easy adsorption with the lower layer when the offset printing takes the sheet, the surface of the transfer layer needs to have the characteristics of high slipperiness. However, at present, general slip additives have the phenomenon of migrating to the surface layer (air-liquid surface), ...

AI Technical Summary

Problems solved by technology

However, general slip agents have the phenomenon of migrating to the surface layer (air-liquid surface), which makes it difficult to achieve high slipperiness on the surface of the transfer coating in contact with the PET film. Varnish is used to improve surface slip, which increases cost and reduces efficiency
