COMPOSITION FOR WALKING PASSAGE MATERIAL AND MATERIAL FOR WALKING PASSAGE

摘要

PURPOSE:To bestow walking feeling having no sense of incongruity for spiked shoes by adding and mixing mineral oil with polynorbornane superior in compatibility with mineral oil, and combining it with sand or sand like mineral substance, while bestowing suitable elasticity. CONSTITUTION:The compositions for walking passage material containing norbornane rubber 100 weight parts, mineral oil 100-500 weight parts, and sand or sand like mineral substance 100-900 weight parts and these compositions are formed in a material for walking passage possible to be processed in extension in a sheet shape. Moreover, polynorbornane occupies at least 50 weight parts in 100 weight parts of rubber as norbornane rubber, synthetic rubber such as SBR having compatibility with oil is contained as other rubber component, and as mineral oil added thereto is paraffin, naphthene, and aromatic one, and A heavy oil and the like is used according to distillation division. Therewith, it is possible to facilitate the construction, to make partial mending possible, and to reduce the construction cost and mending cost.
