Abstract

The invention provides a hot melt adhesive composition for a cold storage label. When the label is pasted, the unit coating amount is small, production efficiency is high, attachment performance is excellent, colloid cohesive strength is high, oil permeability resistance is excellent, and weather resistance is good. The hot melt adhesive composition is prepared from, by weight percentage, 15-25% of first thermoplastic rubber, 10-15% of second thermoplastic rubber, 15-25% of plasticizer, 20-30% of first viscosity increase resin, 20-30% of second viscosity increase resin and 1.0% of antioxygen. The invention further provides a preparation method of the hot melt adhesive composition for the cold storage label.

Description

technical field [0001] The invention relates to the technical field of polyurethane hot-melt adhesives, in particular to a hot-melt adhesive composition for cold storage labels and a preparation method thereof. Background technique [0002] Hot-melt pressure-sensitive adhesive (HMPSA for short) is a type of adhesive that is based on thermoplastic rubber, integrates the characteristics of hot-melt adhesive and pressure-sensitive adhesive, is solvent-free, pollution-free and easy to use. This type of adhesive is applied in a molten state, and after cooling and hardening, it can be quickly bonded with light finger pressure. At present, hot-melt pressure-sensitive adhesives are widely used in automobiles, hygiene products, adhesive tapes, labels, medical care, surface protective films, wood processing and shoemaking. [0003] Hot melt adhesives for cold storage labels generally use SIS rubber as the main polymer. The disadvantage of using traditional SIS rubber is that the inf...
