聚羧酸减水剂改性金属油罐全寿命防腐材料抗老化及微观结构研究

Aging-resistant and Microstructure of Life-time Anti-corrosion of Metal Oil Tanks Improved by Polycarboxylate Water Reducer

通过添加比例不同的聚羧酸减水剂用于改性金属油罐全寿命防腐材料,然后对涂覆样板分别进行常温养护和紫外老化实验并测试其物理性能,最后采用扫描电镜分析了材料试样内部结构的微观形貌,发现样板表面气泡减少,物理性能得到不同程度的改善,而且添加量为1.0%的聚羧酸减水剂对金属油罐全寿命防腐材料的减水效果最优且对防腐材料内部结构的改善也比较明显.

In this paper,different ratios of the polycarboxylate water-reducer were added to improve the life-time anticorrosion material of metal oil tank.Then,painted samples were carried out with the experiments of normal temperature conservation and ultraviolet ray aging.Next,physical properties of samples under experiments were tested.Finally,microcosmic morphologies of samples’ inter structure were analyzed by the SEM.It seemed that bubbles in samples’ surface were decreased and physical properties were improved in different degrees.Moreover,when 1.0%additional amount of polycarboxylate waterreducer was added into the life-time anti-corrosion material of metal oil tank,it showed the best affect of decreasing water and an obviously improvement with microstructure.
