The present invention relates to an aqueous dipping composition for coating a textile reinforcing material, comprising 4.5% to 25% by dry weight of at least one rubber latex, 0.2% to 4.5% by dry weight of at least one blocked isocyanate, 0.3% to 15% by dry weight of at least one filler, 0% to 4% by dry weight of at least one epoxy group-containing compound, and 0% to 2% by dry weight of at least one polymer with carboxylic acid functional groups, wherein the amounts in % by dry weight are based on the total weight of the aqueous dipping composition, wherein the weight ratio of rubber latex to the sum of blocked isocyanate, epoxy group-containing compound and polymer with carboxylic acid functional groups is at least 2, and wherein the composition is essentially free of resorcinol, resorcinol precondensates, formaldehyde and formaldehyde-releasing substances. The present invention further relates to the use of such a composition, to a process for coating a textile reinforcing material with this composition, to a coated textile reinforcing material and a respective elastomeric article comprising the coated textile reinforcing material.
本发明涉及一种用于涂布织物增强材料的水性浸渍组合物,其包含按干重量计4.5%至25%的至少一种橡胶胶乳、按干重量计0.2%至4.5%的至少一种封端异氰酸酯、按干重量计0.3%至15%的至少一种填料、按干重量计0%至4%的至少一种含环氧基的化合物和按干重量计0%至2%的至少一种具有羧酸官能团的聚合物,其中以干重量%计的量基于水性浸渍组合物的总重量计,其中橡胶胶乳与封端异氰酸酯、含环氧基的化合物和具有羧酸官能团的聚合物的总和的重量比为至少2,并且其中所述组合物基本不含间苯二酚、间苯二酚预缩合物、甲醛和释放甲醛的物质。本发明进一步涉及这样的组合物的用途、用这种组合物涂布织物增强材料的方法、涂布的织物增强材料和包含涂布的织物增强材料的各弹性体制品。
