Butyl rubber modified SIS hot-melt pressure-sensitive adhesive

Abstract

The invention discloses a butyl rubber modified SIS hot-melt pressure-sensitive adhesive, including the following raw materials by weight: 50 portions of styrene-isoprene-styrene block copolymer SIS, 50 portions of butyl rubber, 50 portions of C5 petroleum resin, 50 portions of terpene resin, 30 portions of naphthenic oil and 3 portions ofzinc dibutyl dithiocarbamate. The butyl rubber modified SIS hot-melt pressure-sensitive adhesive provided by the invention does not contain organic solvent, is non-toxic, harmless and pollution-free, and has the advantages of higher cohesive strength than a solvent-type pressure sensitive adhesive, fast curing, wide bonding plane, simpleness to manufacture, convenience to use, and a wide range of usage.

Description

[0001] technical field [0002] The invention relates to a hot-melt pressure-sensitive adhesive, in particular to a butyl rubber modified SIS hot-melt pressure-sensitive adhesive. [0003] Background technique [0004] Pressure-sensitive adhesives are adhesives that can be bonded instantaneously with a slight pressure. Usually, there are emulsion methods, solvent methods, and hot-melt methods. Emulsion-type pressure-sensitive adhesives are prepared by emulsion copolymerization of acrylate and modified monomers, and then applying the emulsion to the substrate, and drying to remove moisture. There are problems such as slow drying, poor low-temperature adhesion, and trace residual monomer odor during production. Solvent-based pressure-sensitive adhesives use organic solvents as the medium. After coating, the organic solvents are removed by drying to make pressure-sensitive adhesives. The organic solvents volatilize into the atmosphere to cause pollution, waste resources, and ...

Problems solved by technology

There are problems such as slow drying, poor adhesion at low temperature, and trace residual monomer odor during production

Solvent-based pressure-sensitive adhesives use organic solvents as the medium. After coating, the organic solvents are removed by drying to make pressure-sensitive adhesives. The organic solvents volatilize into the atmosphere to cause pollution, waste resources, and have high costs.
