Abstract

Abstract: High-quality cellulose-acrylic ester molded plastic (CAEMP) was prepared by controlling molding temperature at 140℃, under molding pressure 39.2MPa for 12min. The effects of cellulose particle size, mold discharging agent, polymethyl methacrylate (PMMA) types and the mass ratio of cellulose to PMMA on properties of molded plastics were compared. High performance of molded plastics with 49MPa flexural strength, 2708MPa flexural modulus,1.98kJ/m² impact strength and 0.78% water absorption was obtained under the conditions of cellulose diameter 19μm, the use of PMMA-7 powder, mass ratio of cellulose fiber to PMMA of 75:25 and the use of organosilicon as mold discharging agent.

Key words: cellulose, acrylic ester, molded plastic
