PROBLEM TO BE SOLVED: To provide a method for manufacturing a molded product of a synthetic resin blended with a natural fiber such as waste paper, which draws attention as one method for recycling the waste paper or the measures to reduce a combustion calorie, and eliminates an uncomfortable odor or a gum generated in a mold during thermal molding, and a composition for manufacturing the molded product which is odorless and applied to various uses. SOLUTION: The method for manufacturing a molded product of a resin blended with a natural fiber such as waste paper comprises the steps of melt- kneading a powdered substance of the material fiber such as waste paper and a thermoplastic resin at specified loads to obtain a principal material, then adding a calcium oxide additive containing 0.2 to 5 pts.wt. of calcium oxide to 100 pts.wt. of the principal material and thermally molding the mixture of the principal material and the calcium oxide additive not through undergoing a history of the chemical reaction of the calcium oxide to manufacture the molded product of a resin blended with a natural fiber such as waste paper. In addition, an additive lubricant is added before the thermal molding step. COPYRIGHT: (C)2004,JPO |
