AQUEOUS SLURRY FOR CALCIUM SILICATE HYDRATE AND CALCIUM SILICATE MOLDED ARTICLE MADE FROM SLURRY

摘要

PURPOSE:To obtain aq. slurry for producing calcium silicate molded article having excellent mechanical strength, by compounding calcium silicate hydrate with fiber reinforcement, water-soluble thermosetting cation resin and high polymer latex. CONSTITUTION:The aq. slurry of calcium silicate hydrate is obtd. by dispersing lime material such as quick lime and siliceous material such as silica in water and by heating in satd. steam to react. The aq. slurry is compounded with the fiber reinforcement such as glass fiber, water-soluble thermosetting cation resin such as polyamide-polyamine-epichlorohydrin resin and high polymer latex such as rubber latex, and further, as occasion demands, water-soluble aluminum salt such as aluminum sulfate. The obtd. aq. slurry is dehydrated by pressure filtration, etc., press formed and dried by heating. Thereby, the light and incombustible calcium silicate molded form improved its mechanical strength such as compressive strength, bending strength, etc., is obtd.
