Abstract

The invention relates to a high-persistent-adhesion SIS hot-melt pressure-sensitive adhesive and a preparation method thereof. The high-persistent-adhesion SIS hot-melt pressure-sensitive adhesive is prepared from, by weight, 15-40 parts of SIS thermoplastic elastomer, 10-30 parts of special tackifying resin, 2-8 parts of epoxy resin and 20-80 parts of methylbenzene, and the special tackifying resin is a condensate of butyl phenol and acetylene. The high-persistent-adhesion SIS hot-melt pressure-sensitive adhesive is prepared by adopting a solvent method, takes methylbenzene as a solvent, and consists of the SIS thermoplastic elastomer, the special tackifying resin and a small amount of epoxy resin. The hot melt adhesive is good in raw material compatibility, free of glue leakage in a high-temperature oven environment, excellent in bonding strength, stable in high-temperature resistance, particularly high in holding power, suitable for industrial application, easy to manufacture and wide in application.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, in particular to a high-viscosity SIS hot-melt pressure-sensitive adhesive, and also to a preparation method of the high-viscosity SIS hot-melt pressure-sensitive adhesive. Background technique [0002] Hot-melt pressure-sensitive adhesives are used in a wide range of fields, including packaging products, hygiene products, adhesive labels, medical supplies, textile products, daily necessities, special materials, etc. The main raw materials of hot melt adhesives are basic resins, tackifying resins and other additives, such as plasticizers, anti-aging agents, antioxidants, etc. Among the basic resins, thermoplastic elastomers are mostly used as basic raw materials, especially SIS thermoplastic elastomers. SIS is styrene-isoprene-styrene block copolymer, which is used in the glue matrix to enhance cohesive strength and enhance film-forming properties. An important feature of hot-melt pressure-sensi...
