PROBLEM TO BE SOLVED: To provide a simple and effective manufacturing method of a resin composition requiring no aging process and fully improved in productivity, especially a manufacturing method of a resin composition suitable for a molding material of an artificial marble. SOLUTION: This manufacturing method of a resin composition is putting a monomer component mainly comprising a methacrylate and a solid component mainly comprising a methacrylate polymer and an inorganic filler into a continuous twin-screw kneader and kneading at a temp of 65-120 deg.C to obtain a clay-like substance, then mixing a curing agent into the obtd. clay-like substance during or after cooling. In this case, the monomer component mainly comprising a methacrylate is fed into the continuous twin-screw kneader from an inlet on the downflow side of the inlet of the solid component mainly comprising a methacrylate polymer and an inorganic filler. |
