Elastic material contg. elastic resin particles, binder and cork - useful as base for floor or road, e.g. for indoor or outdoor sports stadium

摘要

Elastic material based on elastic synthetic particles (I) bound with an elastic synthetic resin binder (II), also contains cork particles (III). (I) consist of synthetic rubber, e.g. EPDM and/or SBR, opt. mixed with scrap rubber particles. (II) is a polyurethane resin. The material may also contain gravel and/or sand; and/or the surface may be reinforced, e.g. with a natural and/or synthetic fibre or metal mesh. USE/ADVANTAGE - The material is claimed for use as an elastic base for a floor and/or roadway, esp. for an outdoor or indoor sports stadium, e.g. a gymnasium, football stadium, play area or multipurpose area. It is suitable base for artificial grass for football pitches and other sports and play areas. It is free from materials harmful to the environment and has the reqd. elasticity, durability, wear and load bearing capacity. The insulating properties and reduced weight imparted by (III) make it suitable for numerous other applications, e.g. in the building sector and industry.
