RECLAIMED MATERIAL FOR MANUFACTURING SHOES AND METHOD OF PRODUCING RECLAIMED RUBBER BY PROCESSING RECYCLED SHOE MATERIAL WASTE
20220403146 · 2022-12-22 · ·

A method of producing a reclaimed rubber made of recycled shoe material waste includes the following steps. Step S1: collect a scrap rubber which is the shoe material waste. Step S2: grind the scrap rubber to form scrap rubber granules. Step S3: devulcanize the scrap rubber granules to form a reclaimed rubber. A reclaimed material for manufacturing shoes includes a reclaimed rubber formulation and a crosslinking agent, wherein the reclaimed rubber formulation is constituted by compounding a basic rubber formulation and the reclaimed rubber, wherein the reclaimed material for manufacturing shoes includes 65-94.8 wt % of the basic rubber formulation, 5-30 wt % of the reclaimed rubber, and 0.2 wt % to 5 wt % of crosslinking agent. Mechanical properties of the reclaimed material for manufacturing shoes meet required standards of shoe outsole material. A method of consuming rubber waste produced during the shoe manufacturing process is disclosed herein.

DISSOLVABLE RUBBER
20220372286 · 2022-11-24 ·

A degradable elastomeric material that is formed from a composite blend of elastomeric particles in a continuous degradable binder. The degradable binder is generally a water-soluble binder which has a temperature dependent solubility in water and brine systems. Such degradable elastomers are particularly useful in the fabrication of degradable oil tools, among other applications.
