[0574] In the following production examples, examples, and comparative examples, the measurement and evaluation methods of each characteristic are as follows.

[0575] (Composition and B value of ethylene-α-olefin-non-conjugated polyene copolymer)

[0576] In the ethylene-α-olefin-non-conjugated polyene copolymer, the mass fraction (mass %) of each constituent unit and the B value are determined by 13 The measured value obtained by C-NMR was calculated|required. The measured value was measured by using an ECX400P nuclear magnetic resonance apparatus (manufactured by JEOL Ltd.) with a measurement temperature: 120°C, a measurement solvent: o-dichlorobenzene / deuterated benzene = 4 / 1, and a cumulative number of times: 8000 times to measure the copolymer. 13 C-NMR spectra were obtained.

Abstract

The purpose of the present invention is to provide a laminate of a non-polar or low-polarity rubber that is difficult to adhere to another material, and a dissimilar rubber, laminated with or withoutan adhesive layer interposed therebetween. This laminate includes at least one type of layer selected from layer (1) and layer (2), and at least one type of layer selected from layer (3) and layer (4). At least one layer of the at least one type of layer selected from layer (1) and layer (2), and at least one layer of the at least one type of layer selected from layer (3) and layer (4), are in direct contact or in contact with an adhesive layer interposed therebetween. Layer (1): a layer produced using an ethylene / alpha-olefin / nonconjugated polyene copolymer; layer (2): a layer produced usingan ethylene / carboxylic acid copolymer; layer (3): a layer produced using acrylic rubber; layer (4): a layer produced using a halogen-containing polymer.

Description

technical field [0001] The present invention relates to a laminate and its use. Background technique [0002] Industrial hoses made of rubber are required to have various physical properties such as strength, flexibility, heat resistance, bending resistance, and solvent resistance, but it is difficult to satisfy all the required properties with one type of rubber. Therefore, it is common practice to laminate and use rubbers having different properties. [0003] When laminating dissimilar rubbers, polar rubbers may be directly bonded to other rubbers, and non-polar rubbers are generally bonded via an adhesive layer. [0004] A high level of heat aging resistance, fatigue resistance, oil resistance, etc. is required for a rubber hose around an automobile engine. Therefore, hoses in which expensive fluororubber and acrylic rubber are laminated have been used. When fluororubber and nonpolar rubber are bonded, they are generally bonded via an adhesive layer (for example, refer...
