纳米粉体与聚合物复合可以改善聚合物材料的物理性能和功能特性,特别是当纳米粉体由于自身化学结构和物理特性具有一些特别的功能时,塑料和橡胶的“无卤”阻燃一直是个难点,其阻燃效果和物理性能难以同时兼顾。纳米无机阻燃粉体的出现为解决这一难题带来了希望,特别是对于高粘度状态加工、纳米补强效果显著的橡胶材料潜力很大。本工作以纳米氢氧化镁为分散相,以硅橡胶为连续相,制备了纳米氢氧化镁/硅橡胶复合材料,并对其物理性能和阻燃性能进行了研究。同时,为了进一步强化纳米氢氧化镁与硅橡胶基体间的界面作用对纳米氢氧化镁进行了表面处理。
Composite nanopowder and polymer can improve the physical properties and functional properties of polymer materials, especially when the nanopowders have some special functions due to their own chemical structure and physical properties, the “halogen-free” flame retardant of plastic and rubber has been It is a difficult point, and the flame retardant effect and physical properties are difficult to achieve at the same time. The emergence of nano-inorganic flame-retardant powders brings hope to solve this problem, especially for rubber materials with high viscosity state processing and significant nano reinforcing effect. In this work, nanometer magnesium hydroxide was used as the disperse phase and silicon rubber as the continuous phase. The nanometer magnesium hydroxide/silicone rubber composites were prepared and its physical properties and flame retardant properties were studied. At the same time, in order to further strengthen the interface between nano magnesium hydroxide and silicone rubber matrix, nano magnesium hydroxide was surface treated.
