MULTI-LAYER ELASTIC BLOCK BY USING THE COMPOSITE OF THERMOPLASTIC ELASTOMERS AND WASTE SYNTHETIC RESIN

摘要

A multilayer elastic block using thermoplastic elastomer and waste vinyl is provided to protect pedestrians not to get injured by forming an upper layer of an elastic block with thermoplastic elastomer and waste vinyl and absorbing shock when walking or running, to utilize waste materials and not to be damaged easily by forming a lower layer of an elastic block with waste vinyl and stiffener, and to prevent the separation and interlayer breakdown of an upper layer and a lower layer by forming an adhesive layer made with polyolefin resins and joining the upper layer and lower layer thermally. The multilayer elastic block(10) using thermoplastic elastomer and waste vinyl is formed by piling up an upper layer(20), an adhesive layer(30) and a lower layer(40). The upper layer is formed by making a high elasticity compound with 35~50 percent thermoplastic elastomer and 50~65 percent rubber mixture to have elasticity and provided with many joint projections, the adhesive layer is formed by expansion-molding polyolefin based resins 2~10 times and provided with many through holes to penetrate the joint projections, and the lower layer is formed by making a high strength compound with 30~60 percent waste vinyl and 40~70 percent stiffener and provided with many insertion holes to join with the joint projections.
