    • Chemically treated glass fibers having good processability are useful in producing fiber reinforced polymeric matrices, wherein the glass fibers have controlled wettability and are not detrimental to the weatherability of the fiber reinforced polymeric matrices. The chemically treated fibers have the dried residue of an aqueous chemical treating composition having a bisphenol A polyester film forming polymer compatible with and soluble in the matrix polymer, poly(vinyl acetate) polymeric film former, acryloxy-containing or methacryloxy-containing organo coupling agent in an effective coupling agent amount, cationic fiberous lubricant in an effective lubricating amount, with or without a cationic organic quaternary ammonium salt having alkoxy moieties, and with water in an amount to give a total solid for the aqueous chemical treating composition in the range of about 1 to about 30 weight percent. In addition, the aqueous chemical treating composition can have one or more amino-containing organofunctional silane coupling agents. The amount of the organic quaternary ammonium agent generally is in the range of from 0.05 to around 0.4 weight percent of the aqueous chemical treating composition. When this agent is not in the aqueous chemical treating composition, a secondary application of an antistatic agent is performed. The chemically treated glass fibers can be produced in any form such as chopped strand or continuous strand for combination with polymeric matrices including both filled and unfilled systems for producing reinforced polymeric matrices such as glass fiber reinforced polymeric panels which can be clear, translucent or pigmented.
    • 具有良好加工性能的化学处理玻璃纤维可用于生产纤维增强聚合物基质,其中玻璃纤维具有受控的润湿性,并且不会对纤维增强聚合物基质的耐候性产生不利影响。 化学处理的纤维具有水性化学处理组合物的干燥残余物,其具有与基质聚合物相容并可溶于基质聚合物的双酚A聚酯膜形成聚合物,聚(乙酸乙烯酯)聚合物成膜剂,含丙烯酰氧基或含甲基丙烯酰氧的有机偶联剂 在有效的偶联剂量中,具有有效润滑量的阳离子纤维润滑剂,具有或不具有具有烷氧基部分的阳离子有机季铵盐,以及水的量,其用量为所述水性化学处理组合物的总固体量在 约1至约30重量%。 此外,水性化学处理组合物可以具有一种或多种含氨基的有机官能硅烷偶联剂。 有机季铵化合物的量通常在含水化学处理组合物的0.05至约0.4重量%的范围内。 当该试剂不在水性化学处理组合物中时,进行抗静电剂的二次施用。 化学处理的玻璃纤维可以以任何形式生产,例如短切纤维或连续链,用于与包括填充和未填充体系的聚合物基质组合,用于生产增强的聚合物基质,例如可以是透明,半透明或着色的玻璃纤维增​​强的聚合物面料。
