METHOD FOR MANUFACTURING ELASTIC CYLINDRICAL BODY, METHOD FOR MANUFACTURING ELASTIC ROLL, ELASTIC CYLINDRICAL BODY AND ELASTIC ROLL

摘要

A liquid mixture containing a liquid polymeric materialand a granular filler is injected into a mold for centrifugalmolding and subjected to centrifugal molding, therebypreparing a cylindrical body including a homogeneousdispersion layer having the filler homogeneously dispersed inthe polymeric material and a high-density packed bed, formedon the outer peripheral surface side or on the innerperipheral suface side of the homogeneous dispersion layer,containing the aforementioned polymeric material more denselyfilled with the aforementioned filler. The high-densitypacked bed is removed for exposing the surface of thehomogenious dispersion layer. According to this structure,the yield of the elastic cylindrical body can be improved.
