    • The invention relates to a method for producing a composite from inorganic substances and binders on the basis of silane. The inventive method is characterized by the use of one or more silicon compounds of the general formula (1) as the binder, wherein R represents groups that are the same or different and that cannot be hydrolytically cleaved, and wherein X represents one or more hydroxyl groups or one or more hydrolytically cleavable groups that are the same or different, and n is a number between 0 and 3, preferably between 1 and 2. Said silicon compounds have been previously condensed with understoichiometric amounts of water per mole silicon compound in the presence of alkaline or acidic catalysts. The inorganic substances used are bundles or strands of glass and/or mineral fibers onto which the precondensed silicon compounds have been sprayed in amounts of from 1 to 20% by weight, preferably together with overstoichiometric amounts of water. The strands or bundles so treated are then brought into their final shape and are deformed or compressed to give shaped bodies.
    • 本发明涉及一种基于硅烷从无机物质和粘合剂制备复合材料的方法。 本发明的方法的特征在于使用一种或多种通式(1)的硅化合物作为粘合剂,其中R表示相同或不同且不能水解切割的基团,其中X表示一个或多个羟基 基团或一个或多个相同或不同的可水解切割基团,n为0至3之间,优选1至2之间的数。所述硅化合物在存在下已经预先与少量化学计量的水/摩尔硅化合物缩合 的碱性或酸性催化剂。 使用的无机物质是玻璃和/或矿物纤维的束或股线,其上预先浓缩的硅化合物的喷雾量为1至20重量%,优选与化学计量的水一起喷洒。 然后将如此处理的绞线或束变成其最终形状并变形或压缩以形成成形体。
