Patent number: 6777453Abstract: The object of the present invention is to provide a method of reclaiming crosslinked rubber wherein a reduction of qualities due to generation of decomposed products hardly occurs, and a molding of reclaimed rubber. In a reclamation step of reclaiming crosslinked rubber 10 by applying shear stress thereto and/or in a subsequent step in the present invention, a degasification carrier is introduced and decomposed products in the crosslinked rubber 10 are removed together with the degasification carrier. Also the disclosed is a molding of reclaimed rubber prepared by re-crosslinking reclaimed rubber obtained by this method.Type: GrantFiled: May 3, 2002Date of Patent: August 17, 2004Assignees: Kabushiki Kaisha Toyota Chuo Kenyusho, Toyoda Gosei Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Mitsumasa Matsushita, Makoto Mouri, Hirotaka Okamoto, Kenzo Fukumori, Norio Sato, Toru Yoshida, Masahito Fukuta, Hidenobu Honda, Katsumi Nakashima, Tamotsu Watanabe, Yasuyuki Suzuki, Masao Owaki

Patent number: 6133413Abstract: Devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters. Vulcanized rubber of discarded products is devulcanized by heating it at a temperature of 180.degree. C. --350.degree. C. and applying a shearing pressure of 10-150 kg/cm.sup.2 thereto. Reclaimed rubber products are manufactured by vulcanizing and molding, into desired shapes, a material made of only devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters or a material made of the devulcanized rubber mixed with virgin unvulcanized rubber.Type: GrantFiled: December 18, 1996Date of Patent: October 17, 2000Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki Kaisha, Toyoda Gosei Co., Ltd.Inventors: Makoto Mouri, Arimitsu Usuki, Atsushi Murase, Norio Sato, Yasuyuki Suzuki, Masao Owaki, Kazuya Watanabe, Hidenobu Honda, Katsumi Nakashima, Katsumasa Takeuchi, Masayoshi Ichikawa
