Synthetic Wood Having Elastic Layer

Abstract

The present invention relates to a synthetic wood having an elastic layer, wherein a synthetic wood layer and the elastic layer formed at one side of the synthetic wood layer are formed integrally. According to the present invention, since the elastic layer formed of a rubber material is provided on the upper surface of the synthetic wood, it is possible to increase the contact surface area upon walking and thus improve the anti-slip performance.

1 . A synthetic wood having an elastic layer, wherein a synthetic wood layer and the elastic layer formed at one side of the synthetic wood layer are formed integrally. 
     
     
         2 . The synthetic wood of  claim 1 , wherein the synthetic wood layer is integrally formed with the elastic layer through a dual extruding process. 
     
     
         3 . The synthetic wood of  claim 1 , wherein the elastic layer is composed of 15 to 35 parts by weight of a synthetic resin, 5 to 15 parts by weight of a thermoplastic elastomer, 50 to 70 parts by weight of wood flour and 1 to 15 parts by weight of an additive. 
     
     
         4 . A method of manufacturing a synthetic wood having an elastic layer, comprising:
 extruding a synthetic wood layer through one side of an extrusion mold;   extruding an elastic layer through the other side of the extrusion mold;   forming the synthetic wood layer and the elastic layer integrally with a boundary therebetween; and   cooling the synthetic wood, in which the synthetic wood layer and the elastic layer are integrally formed, to a predetermined temperature.   
     
     
         5 . The method of  claim 4 , further comprising cutting the cooled synthetic wood having the elastic layer in a predetermined length.
