PRODUCTION OF EXTRUSION MOLDED MATERIAL OF HYDRAULIC MATERIAL

摘要

PURPOSE:To obtain an extrusion molded material having high strength, high toughness and excellent surface smopthness by improving the combination effect of a reinforcing material or an admixture. CONSTITUTION:In a producing method for the extrusion molded material of the hydraulic material containing the reinforcing material, a water-soluble cellulose derivative and a sulfonate and/or carboxylate of a polymer having >=100000 weight-average molecular weight are added into the hydraulic material.
