摘要
Abstract
In this paper,the basalt fiber reinforced polypropylene modified materials were prepared by twin-screw extrusion technology,and the three-layer composite pipes PPR/PPR-BF/PPR were prepared by pipe forming equipment.The properties of the modified material and pipes were studied.The results show that when the amount of BF added is 25％,the linear expansion coefficient is as low as 3.7x10-5m/m·℃.Meanwhile,the linear expansion coefficient of the pipe is 4.8× 10-5m/m·℃,indicating that basalt fiber modified PPR pipes can solve the problem of dimensional deformation of PPR pipes during long-term hot water supply.关键词
