    • An aqueous vulcanizable adhesive composition, which comprises a phenol resin emulsion prepared from a water-insoluble phenol resin solution in methyl ethyl ketone and an aqueous water-soluble polymeric substance solution, and a curing agent for phenol resin, uses a partially water-miscible methyl ethyl ketone in place of a completely water-miscible organic solvent, where an amount of methyl ethyl ketone is considerably reduced. PVA, preferably aceto-acetyl-modified PVA, is used as the water-soluble polymeric substance, and the aqueous vulcanizable adhesive composition is suitably used for vulcanization bonding of a metal to (hydrogenated) NBR or acrylic rubber.
    • 一种含水可硫化粘合剂组合物,其包含由甲基乙基酮中的水不溶性酚醛树脂溶液和水溶性聚合物溶液制备的酚醛树脂乳液和酚醛树脂的固化剂,使用部分水混溶性甲基 乙基酮代替完全水混溶的有机溶剂,其中甲基乙基酮的量显着降低。 PVA,优选乙酰 - 乙酰基改性的PVA用作水溶性聚合物,并且该可水性硫化粘合剂组合物适用于金属与(氢化)NBR或丙烯酸橡胶的硫化粘合。
