Abstract

The invention discloses a hot-melt pressure-sensitive adhesive used for sealing a brown paper / bubble bag and a preparation method thereof, which belong to the field of chemical industry. The invention relates to the hot-melt pressure-sensitive adhesive, which solves the problems of low adhesive property and poor weatherability of the hot-melt pressure-sensitive adhesive used for sealing the brown paper / bubble bag. The hot-melt pressure-sensitive adhesive used for sealing the brown paper / bubble bag comprises the following components in parts by weight: 20-30 parts of a SIS thermoplastic elastomer, 5-10 parts of a SBS thermoplastic elastomer, 15-25 parts of naphthenic oil, 5-8 parts of polyisobutene, 40-55 parts of tackifying resin and 0.1-1 part of an anti-oxidant. The method has the advantages of simple process and easy operation, and the product has the advantages of strong bonding force, good initial adhesion, good weatherability and good stability.

Description

technical field [0001] The invention belongs to the chemical industry field and relates to a hot-melt pressure-sensitive adhesive, in particular to a kraft paper / bubble bag sealing hot-melt pressure-sensitive adhesive with thermoplastic rubber SBS / SIS as a base and a preparation method thereof. Background technique [0002] Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive. It is a new type of adhesive made by mixing synthetic rubber, resin and rubber oil into a molten state, and then coating it on the substrate. In recent years, with the establishment of the network platform, the express industry has developed rapidly. The number of express bags and kraft paper / bubble bags used in the express industry has increased sharply. People's packaging requirements for express delivery are also getting higher and higher. The existing For express shipments packed in kraft paper / bubble bags, during transportation or use, the hot-melt pressure-sensitive adhes...
