摘　　要：为提高硅石矿加工过程中废料的利用率,选用硅灰为基料,与植酸锌和硼酸复配,制备硅灰基复合涂料,通过色差仪、锥形量热仪等测试方法研究了紫外线加速老化不同时间后复合涂层的抗老化性能。试验结果表明:植酸锌-硼酸-硅灰基复合涂料具有较好的抗紫外线能力,经14 d老化后,植酸锌-硼酸-硅灰基涂层的颜色变化最小,且涂层表面的泛白现象明显改善;与硅灰基涂层和植酸锌-硅灰基涂层相比,老化后植酸锌-硼酸-硅灰基复合涂层热释放速率峰值的增幅有所降低,该研究为固废资源的利用提供了新途径。In order to improve the utilization rate of waste in the process of silica ore processing,silica fume is selected as the base material and compounded with zinc phytate and boric acid to prepare silica fume-based composite coatings.The anti-aging properties of the composite coatings after UV accelerated ag⁃ing for different time are studied by colorimeter and cone calorimeter.The results show that the zinc phytate boric acid-silica fume based composite coating has good anti-ultraviolet capability.After 14 days of aging,the color change of the zinc phytate-boric acid-silica fume based coating is the smallest,and the whitening phenomenon of the coating surface is obviously improved.Compared with the silica fume-based coating and the zinc phytate silica fume-based coating,the increase of the heat release rate peak of the zinc phytate-bo⁃ric acid-silica fume-based composite coating after aging is reduced.This study provides a new way for the utilization of solid waste resources.
