【摘要】 由于橡胶工业的电镀黄铜工艺大量使用氰化物等剧毒物质,并且黄铜镀层的耐腐蚀性较低,降低了橡胶制品的性能,对此,为提高橡胶制品的使用寿命和减少镀黄铜、涂胶粘剂工艺所带来的污染,采用无污染和耐腐蚀性较好的化学镀镍代替镀黄铜工艺,以实现化学镀镍与橡胶的直接粘合。在试验过程中,进行了Q235钢化学镀镍工艺试验以及NiP镀层和橡胶的粘合试验,用扫描电子显微镜、电子探针和X射线衍射仪等仪器对化学镀NiP合金层的组织结构进行分析并对镀层进行全浸腐蚀试验。用平板硫化机对NiP镀层与橡胶进行硫化粘合试验,用橡胶拉力试验机测定镀层与橡胶的粘合强度。结果结明,所制备的NiP合金镀层具有非晶态结构,镀层均匀致密,与基体的结力好。在硫酸和磷酸等强酸性溶液中,NiP合金镀层的耐腐蚀性高于电镀黄铜层和Q235钢基体。将三聚硫氰酸及其衍生物作为胶料偶联剂添加于胶料中,实现了化学镀NiP合金层与橡胶的直接硫化粘合,粘合强度达到10kN/m。更多还原

【Abstract】 The composition and structure of electroless Ni-P alloy plating were studied using scanning electron microscopy, electron probe microanalysis, and X-ray diffraction, while the corrosion resistance of the plating in sulfuric acid and phosphoric acid was investigated using immersion corrosion test. It was found that the amorphous Ni-P alloy plating had better corrosion resistance than electroplating brass coating. Moreover, it was feasible to realize the direct adhesion of the electroless NiP alloy plating and rubber by introducing tripolythiocyanic acid and its derivative as the coupling agent during the vulcanization process, and the adhesive strength was as much as 10 kN/m.更多还原
