    • PROBLEM TO BE SOLVED: To provide a pneumatic tire containing a tire component having a textile reinforcement exhibiting improved adhesion to rubber. SOLUTION: Single-end aramid cords are treated with an aqueous dispersion of a 1 percent by weight of fine particle ortho-cresol formaldehyde novolac polyepoxide resin by dipping the cords, followed by drying. The cords are then treated with a resorcinol-formaldehyde-latex (RFL) adhesive dip (15 percent by weight of solids) containing an SBR latex, a vinylpyridine-styrene-butadiene latex, a blocked isocyanate, carbon black, and 0.4 to 4 weight percent of polyvinylpyrrolidone based on the total weight of elastomer by dipping the cords, followed by drying. The single-end dipped cords are plied up into layers with both sides coated with a 0.30 mm standard rubber coat compound to make a rubberized single-end dipped cord composite, which is then cured. The composite containing a small amount of polyvinylpyrollidone provides an unexpectedly high level of rubber-cord adhesion as a component of a pneumatic tire. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种含有轮胎部件的充气轮胎,该轮胎部件具有改善的与橡胶的粘附性的纺织增强材料。 解决方案:通过浸渍电线将单端芳族聚酰胺帘线用1重量%的细颗粒邻甲酚酚醛清漆聚环氧树脂的水分散体处理,然后干燥。 然后用含有SBR胶乳,乙烯基吡啶 - 苯乙烯 - 丁二烯胶乳,封闭异氰酸酯,炭黑和0.4-4重量份的间苯二酚 - 甲醛胶乳(RFL)粘合剂浸渍(15重量%固体)处理帘线 基于弹性体的总重量,聚乙烯吡咯烷酮的百分比通过浸渍帘线,然后干燥。 将单端浸渍的帘布层分成两层,两面涂覆有0.30mm标准橡胶涂层化合物,以制成橡胶化的单端浸渍帘线复合材料,然后将其固化。 含有少量聚乙烯吡咯烷酮的复合材料作为充气轮胎的组分提供了意想不到的高水平的橡胶绳粘合。 版权所有(C)2009,JPO&INPIT
