Description
技术领域 technical field
本实用新型涉及一种高分子复合管，尤其涉及一种高分子钢塑耐磨复合管。 The utility model relates to a polymer composite pipe, in particular to a polymer steel-plastic wear-resistant composite pipe.
背景技术 Background technique
超高分子量聚乙烯((UHMW-PE)是1957年首先由美国联合化学公司采用齐格勒催化剂合成成功。它是分子量在100~600万，结晶度65~85，密度0. 92~0. 96g/cm3的一种线型聚合物。与其他聚合物相比，UHMW-PE具有摩擦系数小，耐化学腐蚀，耐冲击、抗冻性、保温性、自润滑性、抗结垢性、耐升裂性、卫生性等优点。国内自上世纪八十年代末开始研究UHMW-PE技术。但由于UHMW-PE分子量高达数百万，超长分子链间的无序缠结，导致熔体粘度高达108Pa .s，流动性极差，加之临界剪切速率极低，使其难以按照常规塑料的加工技术实现加工成型，严重的制约了UHMW-PE的开发应用。 Ultra-high molecular weight polyethylene (UHMW-PE) was first successfully synthesized by United Chemical Company of the United States using Ziegler catalyst in 1957. It has a molecular weight of 1 million to 6 million, a crystallinity of 65~85, and a density of 0.92~0. A linear polymer of 96g/cm3. Compared with other polymers, UHMW-PE has a small friction coefficient, chemical corrosion resistance, impact resistance, frost resistance, heat preservation, self-lubrication, scaling resistance, and Cracking, hygienic and other advantages. The UHMW-PE technology has been studied since the late 1980s in China. However, due to the molecular weight of UHMW-PE as high as several million, the disordered entanglement between ultra-long molecular chains leads to melt viscosity. As high as 108Pa .s, the fluidity is extremely poor, and the critical shear rate is extremely low, making it difficult to realize processing and molding according to conventional plastic processing technology, which seriously restricts the development and application of UHMW-PE.
