  • Patent number: 4626466
    Abstract: There is prepared an aqueous suspension which in addition to water, consists of 2 to 50 weight % of a mixture of bentonite and inorganic fibers, with the portion of inorganic fiber being 1 to 30 weight % and the portion of bentonite being 1 to 30 weight % and wherein the total amount of solids does not exceed 50 weight %. With the suspension there is attained an improvement of the mechanical properties of thermal insulating molded objects which are employed for thermal insulation and which for example, contain pyrogenically produced silica as a filler by delivery of this suspension on the thermal insulating plate. The suspension can also be delivered on thermal insulating molded bodies on which there is pressed a fiber net or a fiber felt. After applying the suspension several thermal insulating molded bodies can be joined together where the coating formed consisting of bentonite and inorganic fibers acts as binder.
