摘要
采用偶联剂对氢氧化铝（ATH）和氢氧化镁（MH）进行表面改性处理，并将其应用于木塑复合材料的环氧树脂基表面防火涂层中。通过显微镜、红外光谱和热失重分析等手段研究了表面处理前后的ATH和MH及其填充量和两者的不同配比对防火涂层的防火性能影响。结果表明：与未经表面改性处理的ATH和MH相比，其经表面改性处理后更有利于提高防火涂层的防火性能；当经钛酸酯偶联剂处理的ATH用量为120份时，表面涂层的防火性能最好；经硅烷偶联剂处理的MH的最佳用量为50份；当ATH／MH质量比为2：1时，防火涂层的防火性能最好，其耐燃时间达到了527S。
Using coupling agent modify the surface of aluminium hydroxide （ATH） and magnesium hy- droxide （MH）. The influence of ATH/MH before and after surface modification treatment and their amount and different rates between ATH and MH on the fire of fireproof coating for wood-plastic composites were stud- ied. The results showed that compared with uncoated ATH and MH, ATH and MH surface modified can im- prove the fire resistance. When the amount of ATH treated by titanate coupling was 120%, the fire retardant coatings had the best performance. 50% of MH modified by silane coupling agent was the optimum amount. The best ratio between AI（OH） 3 and Mg（OH） 2 was 2：1, its flame time reached 527 s.
