摘要
颜料不仅赋予涂膜色彩和遮盖力,还对涂料的流变性、耐候性和耐化学品性有很大影响。本研究以磷酸锌为主要防锈颜料,协同云母氧化铁灰,制备了无溶剂型环氧防腐涂料,对涂层基本性能进行了测试,并利用交流阻抗(EIS)测试技术和中性盐雾试验研究颜料体积浓度(PVC)对涂层防腐性能的影响。结果表明,当PVC小于12%时,涂层具有较好的防腐性能和耐划伤性能。
Pigments can not only provide with colors and hidings for coatings film, but also have effects on coatings＇theological behaviour and the weatherabilsty and chemical resistance. Solventless epoxy anti - corrosion coating was prepared with zinc phosphate, as the main antirust pigment and micaceous iron oxide gray as a synergistic pigment. The effects of PVC on the corrosion resistance of coating were studied through EIS and the salt spray test. The result showed that when the PVC is less than 12%, the coatings exhibited good performance of corrosion and scratch resistance.
