ENVIRONMENT-FRIENDLY WOOD PLASTIC COMPOSITE WITH IMPROVED BIODEGRADABILITY AND MANUFACTURING METHOD THEREOF

摘要

According to the present invention, a manufacturing method of an eco-friendly wood plastic composite with improved biodegradability, which comprises: 50-60 wt% of wood flour having a particle size of 40-120 mesh and having moisture contents of 2-6%; 20-30 wt% of a synthetic resin composed of polypropylene or a high density polyethylene resin; 10-20 wt% of degradable mixed powder containing a fermentation promoter manufactured by heat treating after adding quicklime to ferrous sulfate monohydrate and rice bran powder separated when polishing brown rice to white rice; and 3-10 wt% of calcium carbonate. In addition, the method comprises a mixing process for mixing with a fixed rotation speed under the temperatures of 90-110°C in a heat stirrer by adding an additive.
