PURPOSE:To enable kneading without mixing a contaminant in a product, in kneading a liquid resin and a high hardness inorg particle, by using a high hardness roll having a metal oxide sintered layer at least mounted to the surface thereof. CONSTITUTION:A liquid resin having flowability at a room temp. and viscosity of 100,000cps or less and an inorg. substance having Moh's hardness of 7-10 and a particle size of 50mu or less are kneaded in the presence or in the absence of an org. solvent. In this case, a high hardness roll having one or more sintered layer selected from sintered metal oxide at least mounted to the surface thereof is used. By this method, even if the filling amount of the inorg. substance is much, a kneaded substance suitable for an adhesive, a paint and a mold injection agent can be obtained without imparting abrasion to the roll and mixing a contaminant in a product. |
