Problems solved by technology

For example, the back glue of hot stamping paper cannot be hot stamped with ink and plastic, the back glue of hot stamped plastic cannot be hot stamped with UV ink or frosted ink, and products with a surface tension less than 38 dynes cannot be hot stamped at high speed. The neatness of the edges is also difficult to meet the requirements of high-end customers

Abstract

The invention discloses a high-speed hot stamping gum used for holographic positioning electrochemical aluminium and the preparation method. The gum prepared through the formulation and the method of the invention can achieve good adhesive effect under the appropriate temperature and pressure, and the appropriate release coating is added, thus the holographic image information of the holographic electrochemical aluminium can be stripped and cemented on the surface of the scalded object at the high speed. The fragileness of the gum is moderate, therefore, the trimming performance of the holographic image is good in the hot stamping process, the gum is particularly applied to high-speed hot stamping on the surface of the sheet paper and the printing ink with which the density and the hardness are big, the surface energy is low, the surface wettability is poor, and the general coating liquor is difficult to be transferred and cemented on.

Description

technical field [0001] The invention relates to a hot stamping adhesive and a preparation method thereof, in particular to a high-speed hot stamping adhesive for holographic positioning anodized aluminum and a preparation method thereof. Background technique [0002] In the high-speed automatic hot stamping process, the anodized aluminum holographic image information layer is peeled off from the carrier film (PET) by heating and pressure, and is completely bonded to the surface of various materials through the back adhesive coating, such as (cigarette packs, wine, etc.) bag, plastic, cloth, leather) and other surfaces. However, at present, most of the products in my country's anodized aluminum industry are medium and low-end products, which are difficult to meet the requirements of high-speed automatic hot stamping, especially for products whose surface is difficult to hot stamp, such as grinding oil ink, UU ink and other ink surfaces, PP, PE, ABS Such as plastic surfaces, s...
