SILICA-CONTAINING MODIFIED NATURAL RUBBER MATERIAL AND PRODUCTION METHOD THEREOF

摘要

PROVIDED ARE A SILICA-CONTAINING MODIFIED NATURAL RUBBER LATEX, A SILICA-CONTAINING MODIFIED NATURAL RUBBER MATERIAL, AND A PRODUCTION METHOD THEREOF THAT ALLOW PRODUCTION OF RUBBER PRODUCTS WITH HIGH STRENGTH. THE SILICA-CONTAINING MODIFIED NATURAL RUBBER LATEX IS PRODUCED BY ADDING A VINYL MONOMER HAVING AN ALKOXYSILANE TO A NATURAL RUBBER LATEX TO GRAFT-COPOLYMERIZE THE VINYL MONOMER WITH NATURAL RUBBER PARTICLES AND BY FORMING SILICA BY HYDROLYSIS AND CONDENSATION OF THE ALKOXYSILANE. THE SILICA-CONTAINING MODIFIED NATURAL RUBBER MATERIAL IS PRODUCED BY SOLIDIFYING THE SILICA-CONTAINING MODIFIED NATURAL RUBBER LATEX. THE SILICA-CONTAINING MODIFIED NATURAL RUBBER MATERIAL IS FORMED OF THE NATURAL RUBBER PARTICLES DISPERSED IN A MATRIX OF A GRAFT CHAIN INCLUDING THE FORMED SILICA. FIG. 1
