Abstract
Official abstract text for this publication.
A method for adhering together rubbers to be adhered including a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X1), and carbon black (Y1), using a rubber for adhesion including a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X2), and carbon black (Y2) at an adhesive interface, wherein contents of the organic peroxide (X1) in the rubber to be adhered and the organic peroxide (X2) in the rubber for adhesion are predetermined contents, and a content ratio (X2/X1) of the organic peroxide (X2) to the organic peroxide (X1) is from 1.20 to 2.00.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of adhering together rubbers to be adhered, the method comprising: overlapping the rubbers to be adhered, the rubbers to be adhered including a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X1), and carbon black (Y1), and disposing an adhesive rubber for adhesion at an adhesive interface where the rubbers to be adhered are overlapped, the adhesive rubber including a rubber composition containing an ethylene-α-olefin copolymer, an organic peroxide (X2), and carbon black (Y2), wherein a content of the organic peroxide (X1) in the rubbers to be adhered is from 0.011 to 0.020 molar equivalents relative to the ethylene-α-olefin copolymer in the rubbers to be adhered, a content of the organic peroxide (X2) in the adhesive rubber is from 0.017 to 0.022 molar equivalents relative to the ethylene-α-olefin copolymer in the adhesive rubber, and a content ratio (X2/X1) of the organic peroxide (X2) to the organic peroxide (X1) is from 1.20 to 2.00. 2. The method of adhering according to claim 1 , wherein a content of the carbon black (Y1) in the rubbers to be adhered is from 40 to 60 parts by mass relative to 100 parts by mass of the ethylene-α-olefin copolymer in the rubbers to be adhered, a content of the carbon black (Y2) in the adhesive rubber is from 30 to 50 parts by mass relative to 100 parts by mass of the ethylene-α-olefin copolymer in the adhesive rubber, and a difference (Y1−Y2) in the content between the carbon black (Y1) and the carbon black (Y2) is from 0 to 10 parts by mass. 3. The method of adhering according to claim 2 , wherein the method is used in bonding together conveyor belts. 4. The method of adhering according to claim 1 , wherein the method is used in bonding together conveyor belts.
