<p>A liquid binder containing polyvinylalcohol and a biodegradable packing container using a natural fiber, and a manufacturing method thereof are provided to obtain an uniform strength by uniformly spreading a binder as a combining material without adding the separate water. A liquid binder containing polyvinylalcohol and a biodegradable packing container using a natural fiber, and a manufacturing method thereof comprise the steps of: a liquid binder manufacturing process(S1) for melting a polyvinylalcohol to agitate the water heated at the temperature of 80~100 °C and to mix the polyvinylalcohol of a weight unit of 3~30 applied to the weight unit of 100 of the water; an addition mixing process(S5) for mixing the pigment of the weight unit of 0.2~0.5, the liquid silicate soda of 3~10 as curing agent, the citric acid of 10~30 as softner applied to the manufactured liquid binder of the weight unit of 100; a mixture manufacturing process(S2) for mixing the liquid binder of the weight unit of 60~70 applied to the wooden powder of the weight unit of 100 as the natural fiber to cool the liquid binder mixed with the addition at a room temperature; an extrusion molding process(S3) for extruding the mixture for 1~5 minutes by being input into a molding device applied to the heat of 80~150 °C; and a curing process(S4) for curing a molding product by mounting the manufactured extrusion molding material for 10~20 minutes.</p> |
