摘　　要：采用硅烷偶联剂(KH-570)和丙烯酸丁酯(BA)分别对玻纤进行表面处理,研究不同表面处理方法对无规共聚聚丙烯(PP-R)/玻纤复合材料拉伸强度的影响;研究玻纤对PP-R材料性能的影响,以期提高材料强度,降低其热膨胀系数,并进一步将其应用于PP-R管材生产,可望实现PP-R管材的轻量化,减少管卡用量,提高安装效率。Silane coupling agent(KH-570)and butyl acrylate(BA)were used for surface treatment of glass fiber respectively.The effect of different surface treatment methods on the tensile strength of random copolymerized polypropylene(PP-R)/glass fiber composites was studied.Glass fiber modified random copolymer polypropylene(PP-R)special material for pipes was prepared to improve the strength of material and reduce the coefficient of thermal expansion.Thus,the weight of PP-R pipe can be lightened.Further,the amount of pipe clamp can be reduced greatly improving the efficiency of construction.
