The invention relates to a sulfur-crosslinkable rubber coating mixture for metal or textile tire cords, said mixture containing at least one novolac resin which contains alkyl urethane units and is produced by reacting a phenol compound, an aldehyde and a urethane resin, the urethane resin is produced by reacting an alkyl urethane with an aldehyde, the mixture further containing at least one etherified melamine resin. The invention further relates to a pneumatic vehicle tyre comprising at least one such sulfur-crosslinked rubber-coating mixture. In order to improve the durability of the rubber-coated tire cords, the rubber-coating mixture contains less than 2.5 phr (parts by weight, based on 100 parts by weight of all the rubber in the mixture) of at least one novolac resin, the present invention relates to a composition comprising:-a novolac resin comprising alkyl urethane units and produced by reacting a phenol compound, an aldehyde, and a urethane resin produced by reacting alkyl urethane with an aldehyde, and-less than 2.5 phr of at least one etherified melamine resin.

    本发明涉及一种用于金属或织物轮胎帘线的硫可交联的橡胶‑涂布混合物,所述混合物含有至少一种酚醛清漆树脂,该酚醛清漆树脂包含烷基氨基甲酸乙酯单元并且通过使苯酚化合物、醛和氨基甲酸酯树脂反应产生,该氨基甲酸酯树脂通过使烷基氨基甲酸乙酯与醛反应产生,该混合物还含有至少一种醚化三聚氰胺树脂。本发明进一步涉及一种充气车辆轮胎,其包含至少一种这样的硫交联的橡胶‑涂布混合物。为了改进这些橡胶‑涂布的轮胎帘线的耐久性,该橡胶‑涂布混合物含有‑小于2.5phr(重量份,基于100重量份的该混合物中的所有橡胶)的至少一种酚醛清漆树脂,该酚醛清漆树脂包含烷基氨基甲酸乙酯单元并且通过使苯酚化合物、醛和氨基甲酸酯树脂反应产生,该氨基甲酸酯树脂通过使烷基氨基甲酸乙酯与醛反应产生,以及‑小于2.5phr的至少一种醚化三聚氰胺树脂。
