Adhesive composition, bonding method, laminate and tire |
摘要 |
An object of the present invention is to provide an adhesive composition which can bond a film to unvulcanized rubber strongly, and is flexible and rarely undergoes cracking under low temperature conditions; and a method for bonding a film to unvulcanized rubber using the adhesive composition. In addition, an object of the present invention is to provide a laminate formed by the bonding method; and a tire produced using the laminate. The adhesive composition of the present invention contains a polymer component which has a glass transition temperature or both a glass transition temperature and a melting point of 40° C. or lower, has a main chain having a random structure, has epoxy groups, and has sulfur-crosslinkable sites. The bonding method of the present invention is characterized by using the adhesive composition. |

1. A laminate formed by a method for bonding a film to an unvulcanized rubber, comprising: disposing an adhesive composition between the film and the unvulcanized rubber and then vulcanizing the unvulcanized rubber to bond the film to the unvulcanized rubber, wherein
the adhesive composition comprises a polymer component, wherein the polymer component has a glass transition temperature of 40° C. or lower if it does not have a melting point, or both a glass transition temperature and a melting point of 40° C. or lower if it has a melting point, has a main chain having a random structure, has epoxy groups and has sulfur-crosslinkable sites, and further wherein the polymer component comprises a high molecular weight polymer having a weight average molecular weight of 150000-2000000. |
