Embodiment Construction

[0029] The composition for laminates of the present invention contains at least: an epichlorohydrin-based polymer (a), a compound (b) having a vinyl group selected from the group consisting of 1,8-diazabicyclo(5.4.0)undecene- 7 salt, 1,5-diazabicyclo(4.3.0)-nonene-5 salt, 1,8-diazabicyclo(5.4.0)undecene-7 and 1,5-diazabicyclo (4.3.0)-At least one compound (c) from the group consisting of nonene-5, and a metal salt hydrate (d).

[0030] The epichlorohydrin-based polymer (a) used in the composition for laminates of the present invention is a polymer having a structural unit derived from epichlorohydrin, and may contain alkanes, propylene oxide, n-butane oxide, etc.), glycidyls (such as methyl glycidyl ether, ethyl glycidyl ether, n-glycidyl ether, allyl glycidyl ether, phenyl glycidyl ether, etc. ) structural unit. Specifically, epichlorohydrin homopolymer, epichlorohydrin-ethylene oxide copolymer, epichlorohydrin-propylene oxide copolymer, epichlorohydrin-ethylene oxide-allyl...

Abstract

This composition for laminates is characterized by containing: (a) an epichlorohydrin polymer; (b) a compound having a vinyl group; (c) at least one compound selected from the group consisting of 1, 8-diazabicyclo(5. 4. 0)undecene-7 salts, 1,5-diazabicyclo(4. 3. 0)-nonene-5 salts, 1, 8-diazabicyclo(5. 4. 0)undecene-7 and 1,5-diazabicyclo(4. 3. 0)-nonene-5; and (d) a metal salt hydrate.

Description

technical field [0001] This invention relates to the composition for laminated bodies. Background technique [0002] In recent years, regulations on the management of vehicle exhaust emissions have become very stringent, and one of them, the regulations on the management of gasoline volatilization has been increasingly strengthened mainly in the United States. In response to these stringent requirements, in terms of automotive fuel hoses, we are also developing fuel hoses that combine heat aging resistance, weather resistance, deterioration gasoline resistance, alcohol-containing gasoline resistance, gasoline impermeability, etc. As one of the fuel hose materials, a fluorine-containing polymer is mentioned. However, since it is expensive and also has problems in cold resistance, a laminate in which a fluorine-containing polymer is used for the inner layer and epichlorohydrin-based rubber is used for the outer layer is often used. [0003] However, in the case of a laminate...
