JOURNAL FREE ACCESSVulcanized rubbers were comminuted to particle diameter with 1-5mm by cutting mill. Then, the particles wer mixed with filler such as silica at roughly 100-150°C in mixer and twin screw extruder. Fine powders of rubber wastes having the mean particle diameter of about 297-500μm were obtained. It can be expected that this method is utilized to the recycling of a rubber waste.View full abstractDownload PDF (906K) -

No.8 (Final): The Origin of Weakness and Reinforcement of ElastomersYoshihide FUKAHORI2005 Volume 78 Issue 1 Pages 19-25
Published: 2005
Released on J-STAGE: May 19, 2008
JOURNAL FREE ACCESSThe author proposes the universal model for the cross-linked structure of real rubber vulcanizates, characterized by the heterogeneous networks of a densely cross-linked and a on-cross-linked phase, the volume fraction being 75-80% in the former and 20-25% in the latter. Fundamentally, the densely ross-linked phase is discontinuously structured in the system, surrounded by the continuous non-cross-linked phase.
If we will accept the above concept, we should carefully reconsider the applicability of the rubber elasticity theory (Gaussian or non-Gaussian) based on the assumption of homogeneous cross-linking to real rubber vulcanizates, concerning the affine deformation, the stress-strain relation, the visco-elasticity and the fracture of rubbers.
In this final report, we would like to summarize the origin of the strength and weakness of rubbers, spreading rubber species to thermoplastic and thermosetting elastomers and polyurethane.View full abstractDownload PDF (1816K) -
1. Effects of Inorganic Fillers on the Properties of VulcanizatesSoji Kodama2005 Volume 78 Issue 1 Pages 26-32
Published: 2005
Released on J-STAGE: May 19, 2008
JOURNAL FREE ACCESSBecause of lower reinforcement effects on physical properties of vulcanizates than carbon black, inorganic fillers such as silica have been used in a rubber industry supplementary. Recently, necessity of inorganic fillers is recognized for development of high performance and high functional vulcanizates. This paper is referred to properties of inorganic fillers and vulcanizates loaded with them and possibilities of development with loading inorganic fillers.View full abstractDownload PDF (1191K) -
