Problems solved by technology

As the market demand for self-adhesive labels increases, the existing production speed cannot meet the market demand, and the production speed of the label material depends on the die-cutting speed of the label material, which is related to the label glue used. and its close relationship
During the die-cutting process of the existing label glue, the die-cutting speed is usually only 20-50m / min. If the speed is increased, there will be bad phenomena such as poor waste discharge, flying marks, and edge breakage. The cutting speed of the label glue is of great significance

Abstract

The invention relates to the field of polymer adhesives, and in particular to a label adhesive capable of high-speed die cutting and a preparation method thereof. The label adhesive capable of high-speed die cutting comprises the following components: SBR (Styrene Butadiene Rubber), hydrogenated C5 / C9 copolymerized petroleum resin, rosin modified phenolic resin, citrate, a functional auxiliary agent and an antioxidant. The label adhesive capable of high-speed die cutting prepared by the invention enables a product to have better high-speed die cutting performance while excellent initial adhesion and peeling performances are kept so as to meet conventional performance and rapid processability. In addition, the label adhesive capable of high-speed die cutting prepared by the invention has strong wettability to the substrate and good thermal stability.

Description

technical field [0001] The invention belongs to the technical field of polymer adhesives, and more specifically relates to a high-speed die-cut label glue and a preparation method thereof. Background technique [0002] Self-adhesive label material is a composite material with paper, film or special material as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. In the 1930s, self-adhesive materials were first applied in the United States. Due to the continuous expansion of the demand for this special composite material, self-adhesive printing has gradually evolved into an independent printing field. more and more companies. [0003] The main markets for self-adhesive labels are food and beverage, consumer durables, pharmaceuticals, household and personal care products, and industrial and retail label markets. In the future, with the growth of urban population, people's demand for medical supplies will continue to increase; at the sam...
