Abstract
Official abstract text for this publication.
The present invention relates to an adhesive composition including: a butyl-based rubber; and a tackifier having a softening point of 90° C. or more.
First claim
Opening claim text (preview).
1 . An adhesive composition comprising: a butyl-based rubber; and a tackifier having a softening point of 90° C. or more. 2 . The adhesive composition of claim 1 , wherein the butyl-based rubber includes at least one selected from the group consisting of a butyl rubber, a bromo-butyl rubber, and a chlorinated butyl rubber. 3 . The adhesive composition of claim 1 , wherein the butyl-based rubber has a weight average molecular weight of 50,000 to 2,000,000. 4 . The adhesive composition of claim 1 , wherein the butyl-based rubber is formed by polymerizing a mixture including 1 mol % to 5 mol % of isoprene relative to 100 mol % of the total monomer. 5 . The adhesive composition of claim 1 , wherein the butyl-based rubber has an amount of 50wt % to 90 wt % relative to total weight of the adhesive composition. 6 . The adhesive composition of claim 1 , wherein the tackifier is a rosin-based resin, a rosin ester-based resin, a linear hydrocarbon-based resin or a cyclic olefin-based resin to which hydrogen is added. 7 . The adhesive composition of claim 1 , wherein the tackifier has a weight average molecular weight of 500 to 2,000. 8 . The adhesive composition of claim 1 , wherein the tackifier has an amount of 5 wt % to 40 wt % relative to total weight of the adhesive composition. 9 . The adhesive composition of claim 1 , further comprising: at least one selected from the group consisting of a UV curing agent, a UV stabilizer, a photoinitiator, a thermal initiator, an antioxidant, a filler and a plasticizer. 10 . The adhesive composition of claim 1 , wherein a water vapor transmission rate (WVTR) of the adhesive composition is 10 g/m 2 ·24 hr at a temperature of 38° C. and relative humidity of 90%.
