MANUFACTURE OF EXTRUSION MOLDED MATTER OF HYDRAULIC SUBSTANCE

摘要

PURPOSE:To manufacture an extrusion molded matter superior in high strength, high tenacity and explosion-fracture resistance, by a method wherein a hydraulic substance containing a reinforcement material is extrusion-molded stably by low extrusion pressure. CONSTITUTION:A water-soluble cellulose derivative and sulfonate of a conjugated diene polymer are added to a hydraulic substance. It is effective further when an isoprene polymer is used for the conjugated diene polymer.
