The effects of different additives on mechanical properties of acrylic were studied by orthogonal test, using methyl methacrylate as raw material, concentration of initiator(azobisisobutyronitrile), plasticizer (Dibutyl Phthalate) and release agent(Stearic Acid) as the influence factors. The results show that: among the three additives, initiator is the most significant factor, which has the greatest impact on the mechanical properties of acrylic. With increasing of initiator content, the tensile strength of acrylic decreases. The effect of plasticizer and release agent on the mechanical properties of acrylic is relatively small. As the increase of plasticizer content, the tensile strength and bending strength decline. Finally, the best ratio of the three additives is initiator=0.06, plasticizer=3.0, release agent=1.0.
