▎ 摘  要

NOVELTY - A refractory material is prepared by kneading a raw material comprising (a) at least one of starch and powder of unused portion of starch, (b) sodium bicarbonate and (c) polyvinyl alcohol (PVA), and additive as main component, and drying by at least one chosen from naturally drying, electro-drying, vacuum-drying and electromagnetic wave irradiation drying. The refractory material has a refractory temperature of 2100 degrees C. The weight ratio of the component (a), component (b) and the component (c) is 100:2-100:10-150. The additive is at least one chosen from carbide layers, carbon fibers, polyimide fibers, graphene, aramid fibers, polybenzimidazole fibers, carbon nanotubes, preservative and insect repellent. USE - Refractory material used as building material. ADVANTAGE - The lightweight refractory material is easily and economically prepared. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of the refractory material, which involves kneading the raw materials and drying.
