摘　　要：用硅烷类表面改性剂对结晶氢氧化镁进行了表面改性,并对EVA进行了复合添加研究,获得以复合高分子材料优良机械性能和阻燃性能为判据的最佳添加条件为:改性时间0.5 h,改性温度110℃,改性剂用量2%.针对氢氧化镁添加量等因素对材料物理性能带来的影响机理提出了自己的见解.The process of surface modification for crystalline magnesium hydroxide was investigated by using the Silane coupling agent as a surface modification agent. Its multiple application in EVA was also put forward. The experimental result shows that the optimal modification time is 0.5h, the best modification temperature is 110℃, and the best dosage of the modifier is 2%. Furthermore, the flame retardant and mechanical properties are also improved greatly by adding modified Mg（OH）2 into flexible EVA. The factors affecting the physical properties of the materials are discussed, such as the dosage of the modifier.
