Biodegradable environment protective pad and method of manufacturing the same

Abstract

A biodegradable environment protective pad and a method of manufacturing the same. The method includes the steps of: leveling a middle net fabric; inserting the middle net fabric between two rollers for transporting the middle net fabric; coating a polymeric material on the middle net fabric; baking the middle net fabric to foam or cure the coated polymeric material; and cooling the middle net fabric to harden the polymeric material.

1 . A biodegradable environment protective pad, comprising:
 a middle net fabric having an upper surface and a lower surface; and   at least one polymeric material layer coated on one of the upper and lower surfaces of the middle net fabric, wherein the polymeric material layer is formed of a predetermined formula, which is mainly composed of a polymeric natural material, an environment protective dloctyl alcohol ester and a polyvinyl chloride (PVC).   
   
   
       2 . The pad according to  claim 1 , wherein the polymeric material layer is mainly composed of the dloctyl alcohol ester, the polyvinyl chloride (PVC) and a polymer-natural. 
   
   
       3 . The pad according to  claim 2 , wherein the polymer-natural is vegetable jelly, fibrin or amylase. 
   
   
       4 . The pad according to  claim 1 , wherein the polymeric material layer is mainly composed of a polymer-natural, which may be vegetable jelly, fibrin, or amylase, cross-linking with a polyol and a Isocyanate or acrylic resin, or mixing with a polyolefin material TPO or TPV, which pertains to a thermalplastic elastomer (TPE). 
   
   
       5 . A method of manufacturing a biodegradable environment protective pad, the method comprising the steps of:
 providing and leveling a middle net fabric and continuously outputting the middle net fabric;   inserting the middle net fabric between rollers for transporting the middle net fabric;   coating a polymeric material formed of a predetermined formula on the middle net fabric;   baking the middle net fabric until the polymeric material foams or cures; and   cooling the middle net fabric to harden the polymeric material.   
   
   
       6 . The method according to  claim 5 , wherein the middle net fabric is composed of a polymer of a polyester fiber, or a natural plant fiber including jute, cotton and bamboo charcoal. 
   
   
       7 . The method according to  claim 5 , wherein the coating step is performed through at least one coating machine filled with the polymeric material, and the coating machine is disposed on at least one of upper and lower surfaces of the middle net fabric. 
   
   
       8 . The method according to  claim 5 , wherein the baking step is performed in a baking area having a predetermined high-temperature, and the baking area comprises two high-temperature units or one high-temperature unit and one ultra-high-temperature unit disposed on upper and lower surfaces of the middle net fabric. 
   
   
       9 . The method according to  claim 5 , wherein the cooling step is performed in a low-temperature area capable of instantaneous cooling. 
   
   
       10 . The method according to  claim 5 , further comprising a cutting step of directly cutting the middle net fabric coated with the polymeric material into sheet-like pads through operations of a cutting machine or further through an automatic counter.
