What is disclosed are bonded articles of a peroxide cured elastomer and a substrate which an adhesive composition that exhibits substantial environmental resistance and rubber tearing bonds. The invention is also directed to adhesives consisting essentially of water, a phenol-aldehyde condensate, an etherified bis phenol aldehyde adduct and PVOH colloid protectant, optional polymeric film former, acid scavenger and precipitated silica. The present invention is further directed to a method of bonding peroxide-curable elastomers to metallic surfaces whereby the substrate is coated with the adhesive composition, drying the adhesive composition coating, applying a peroxide-cured elastomer to the adhesive composition coating, and curing the assembly with heat and/or pressure.
本发明公开了一种过氧化物固化弹性体和基材的粘合制品,其粘合剂组合物具有很强的耐环境性和橡胶撕裂粘合性。本发明还涉及主要由水、苯酚-甲醛缩合物、醚化双苯酚醛加合物和 PVOH 胶体保护剂、任选聚合物成膜剂、酸清除剂和沉淀白炭黑组成的粘合剂。本发明还涉及一种将过氧化物固化弹性体粘合到金属表面的方法,在该方法中,用粘合剂组合物涂覆基材,干燥粘合剂组合物涂层,将过氧化物固化弹性体涂覆到粘合剂组合物涂层上,并用热量和/或压力固化组件。
