Embodiment 1～6

[0076] The rubber component (A), the mixture composition (B), and the styrene thermoplastic elastomer composition (C) were mixed in the proportions shown in Table 1. That is: the styrene thermoplastic elastomer (C) is mixed in a ratio of not less than 2 parts by weight and not more than 100 parts by weight with respect to 200 parts by weight of the mixture composition (B). EPDM was used as the rubber component.

Abstract

An elastomer composition is prepared that contains a rubber component (A) containing at least one of diene rubber and EPDM rubber; a mixture composition (B) containing hydrogenated styrene thermoplastic elastomer and olefin resin; and a styrene thermoplastic elastomer (C) having double bonds partly left, wherein the styrene thermoplastic elastomer (C) is blended at a ratio of not less than 2 parts by weight and not more than 100 parts by weight with respect to 200 parts by weight of the mixture composition (B), and the rubber component (A) is dispersed by dynamic crosslinking in the mixture composition (B) having the styrene thermoplastic elastomer (C) dispersed therein. A rubber roller is formed by using the elastomer composition. The elastomer composition is excellent in wear resistance, and the rubber roller made of the elastomer composition is excellent in wear resistance at the time of idling rotation.

Description

technical field [0001] The present invention relates to an elastomer composition and a rubber roller formed using the elastomer composition. More particularly, the present invention relates to an elastomer composition having extremely excellent abrasion resistance while having appropriate hardness, which is suitable for use in OA equipment such as inkjet printers, laser printers, xerographic copiers, or facsimile The rubber roller in the paper feeding device of machine, automatic teller machine etc., also relates to its preparation method simultaneously. Background technique [0002] The paper feeding rubber roller made of rubber composition, elastomer composition or similar composition is used in the paper feeding device of OA equipment such as: inkjet printer, laser printer, electrostatic copier or fax machine, automatic teller machine (ATM), etc. Used to convey paper, film, etc. [0003] In recent years, OA apparatuses for private use have dramatically increased in numb...
