FLY ASH COMPOSITION FOR PREPARING A LIGHT-WEIGHT MOLDED FOAM ARTICLE AND METHOD FOR PRODUCING A LIGHT-WEIGHT MOLDED FOAM ARTICLE USING THEM AND A LIGHT-WEIGHT MOLDED FOAM ARTICLE MADE THEREBY

摘要

The present invention is to provide a lightweight foam molded body and, more particularly, to a composition including fly ash for manufacturing a porous lightweight foam molded body. Disclosed is a composition for manufacturing a fly ash lightweight foam molded body, with respect to 100 parts by weight of a mixture including 50-80 wt% of fly ash and 20-50 wt% of alkali silicate, including 4-8 parts by weight of alkali hydroxide, 1-5 parts by weight of acid, 1-5 parts by weight of a strength reinforcement, and 1-10 parts by weight of water. In addition, the present invention relates to a method for manufacturing a porous lightweight foam molded body using the composition and the foam molded body and, more particularly, to a method for manufacturing a lightweight foam molded body using porous fly ash having excellent high strength, high heat resistance, heat insulation properties, and sound absorption properties.
