PP/nano-ATH复合材料性能研究

Study on Properties of PP/Nano-ATH Composite

采用熔融共混法制备出聚丙烯(PP)/纳米氢氧化铝(nano-ATH)复合材料,研究了nano-ATH的用量对复合材料力学性能和阻燃性能的影响。结果表明,随着nano-ATH用量的增加,PP/nano-ATH复合材料的冲击强度和拉伸强度均呈现先增加后降低的趋势,而弯曲模量呈增加趋势,且nano-ATH的加入,有助于改善PP的阻燃性能。

Polypropylene/nano-aluminum hydroxide（PP/nano-ATH）composite was prepared by melt blending method.The effect of the nano-ATH amount on the mechanical and flame retardant properties of the PP/nano-ATH composite was studied.The results showed that the impact strength and tensile strength of the PP/nano-ATH composite both increased with the increase of nano-ATH content,and then decreased,while the flexural modulus of the PP/nano-ATH composite evidently increased.The addition of the nano-ATH was beneficial to improve the flame retardant property of PP.
