    • A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises a reaction product of a multi-aldehyde or multi-ketone and a phenolic compound. When heated, the reaction product undergoes curing to form a water-insoluble cured benzohydro-benzofurane binder which exhibits good adhesion to glass. In a preferred embodiment, a reaction product of a multi-aldehyde and a phenolic compound having more than one phenolic group initially is formed. The fiberglass can be provided in various configurations when bound by the binding composition of the present invention, and preferably is in the form of a non-woven. In a particularly preferred embodiment, the final product is a mat or building insulation.
    • 提供了一种与玻璃纤维一起使用的可固化的不含甲醛的结合组合物。 这种可固化组合物包含多醛或多酮和酚类化合物的反应产物。 当加热时,反应产物固化,形成对玻璃具有良好粘附性的水不溶性固化苯并氢 - 苯并呋喃粘合剂。 在优选的实施方案中,最初形成多醛和具有多于一个酚基的酚类化合物的反应产物。 当结合本发明的结合组合物时,玻璃纤维可以以各种构型提供,优选为无纺布形式。 在特别优选的实施方案中,最终产品是垫子或建筑物绝缘体。

    • A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an acid-catalyzed reaction product of an aldehyde or ketone with a multihydric alcohol. When heated, the composition forms polyacetal or polyketal that undergoes curing to form a water-insoluble resin binder which exhibits good adhesion to glass. In a preferred embodiment, maleic anhydride initially serves as a catalyst and subsequently enters into a cross-linking reaction during curing to form a poly(ester-acetal). Also, in a preferred embodiment, the fiberglass is in the form of building insulation. In other embodiments the product can be a microglass-based substrate for use in a printed circuit board, battery separator, filter stock, or reinforcement scrim.
    • 提供了一种与玻璃纤维一起使用的可固化的不含甲醛的结合组合物。 这种可固化组合物包含醛或酮与多元醇的酸催化反应产物。 当加热时,组合物形成聚缩醛或聚缩酮,其经历固化以形成对玻璃具有良好粘附性的水不溶性树脂粘合剂。 在优选的实施方案中,马来酸酐最初用作催化剂,随后在固化期间进入交联反应以形成聚(酯 - 缩醛)。 而且,在一个优选实施例中,玻璃纤维是建筑隔热的形式。 在其它实施方案中,该产品可以是用于印刷电路板,电池隔板,过滤材料或增强稀松布的基于玻璃基的基底。
