Abstract
Official abstract text for this publication.
The present invention relates to a rubber-based adhesive composition containing: a styrene-butadiene-styrene (SBS) rubber; a hardener; and an adhesion enhancer, the adhesion enhancer being contained in 50 to 100 parts by weight based on 100 parts by weight of the styrene-butadiene-styrene (SBS) rubber, and to a rubber-based adhesive tape for an automobile using the same.
First claim
Opening claim text (preview).
1 . A rubber-based adhesive composition comprising a styrene-butadiene-styrene (SBS) rubber; a hardener; and an adhesion enhancer, wherein an amount of the adhesion enhancer ranges from 50 parts to 100 parts by weight based on 100 parts by weight of the SBS rubber. 2 . The rubber-based adhesive composition of claim 1 , wherein a styrene amount of the SBS rubber ranges from 20 wt % to 30 wt %. 3 . The rubber-based adhesive composition of claim 1 , wherein the hardener is at least one selected from the group consisting of 1,6-hexanediol diacrylate, dipentaerythritol hexaacrylate, tetramethylolmethane tetraacrylate, tetramethylolmethane triacrylate, trimethylolpropane triacrylate, 1,6-bis(3-acryloyloxy-2-hydroxypropyloxy)hexane, polyethylene glycol diacrylate, pentaerythritol triacrylate, and a hexamethylene diisocyanate urethane prepolymer. 4 . The rubber-based adhesive composition of claim 1 , wherein the adhesion enhancer is a hydrogenated ring-type olefin-based resin. 5 . The rubber-based adhesive composition of claim 1 , wherein a softening point of the adhesion enhancer is 90° C. or higher. 6 . The rubber-based adhesive composition of claim 1 further comprising at least one selected from the group consisting of an ultra-violet (UV) stabilizer, a photoinitiator, a thermal initiator, an antioxidant, a filler, and a plasticizer. 7 . A rubber-based adhesive tape for an automobile, the tape comprising an acryl foam layer; and a rubber-based adhesive layer prepared by hardening the rubber-based adhesive composition of claim 1 , wherein the rubber-based adhesive layer is formed on both surfaces of the acryl foam layer. 8 . The rubber-based adhesive tape of claim 7 , wherein a hardening degree (a gel amount) in the rubber-based adhesive layer ranges from 30% to 50%.
