The present invention relates to a composite resin using a material which is harmless to the human body and which is easy to be processed but has a high strength and which has high machinability by reducing the content of silica, (TMPTA)) and trimethylolpropane triacrylate (TMPTA) were mixed, and the mixture was stirred at room temperature for 1 hour, A step of preparing a polymer compound, a step of preparing a silica to produce silica using barium aluminosilicate, a step of mixing the polymer compound produced in the step of preparing the polymer compound with the silica prepared in the step of preparing silica, , A polymerization initiator, and an antidustence agent to prepare a mixture; and a step of mixing the horn prepared in the sample mixing step And a defoaming and curing step of producing a composite resin by defoaming and curing the mixture in a vacuum to reduce the content of silica to thereby improve the machinability of the resin and reduce the content of silica to facilitate the processing, And a method of manufacturing the same. |
