摘　　要：　从物理补偿、玻纤复合、纳米改性等方面探讨了降低PP R管线性膨胀系数的方法,通过纳米材料对PP R改性,使PP R管材的线性膨胀降低了71 9%,解决了PP R使用中的线性膨胀问题。Methods of reducing the linear expansion coefficient of PP-R pipes were discussed from several aspects such as physical compensation,glass fibre compound and nano-modification.The linear expansion coefficient of PP-R pipes was de-creased by71.9%after PP-R modified by use of nano-material,and the problem of linear expansion of PP-pipes were solved.
