发明名称 NOVEL ENVIRONMENTAL-PROTECTION SHOE TREE
摘要 The present invention relates to the manufacture of a novel environmental-protection shoe tree, and particularly to the manufacture of an environmental-protection shoe tree made by molding a primary material of rice husk, in which fibrous plant materials, such as rice husks and wheat husks are sieved and pulverized and are mixed with natural rubber and additives, followed by mechanical mixing to carry out a uniform mixing operation for forming an environmental-protection material block, which is then processed by a rolling machine to uniformly mix with a crosslinking agent and form an environmental-protection material plate, which is then cut into a desired size and put in a mold to be heated and pressurized by a hydraulic machine for performing molding to eventually form a final product of a shoe tree showing characteristics of environmental protection.
