摘要：
Traditional flame retardant has the problem of poor compatibility, it is a effective way to solve the problem by using microcapsule technology to modify the surface of flame retardant. Microencapsulated aluminum hydroxide (MATH) was prepared by sol-gel method and characterized. The mechanical properties, flame retardancy, and smoke suppression of SiFs containing MATH were studied by universal tensile tester, limiting oxygen index tester, smoke density tester, and cone calorimeter. These results show that the encapsulation effect is good and the thermal stability of the ATH is improved after microencapsulation. MATH could effectively improve the flame retardancy and smoke suppression of SiFs without reducing the mechanical properties. Besides, the thermal oxidative decomposition process, structure of residual carbon of SiFs were studied, and the flame retardant and smoke suppression mechanism of MATH/SiFs were analyzed. © 2021, Editorial Board of Polymer Materials Science & Engineering.
