用分子量380万的超高分子量聚乙烯(UHMWPE)树脂为基体树脂,加入高含量导电炭黑/聚乙烯蜡复合导电剂,溴-锑系与膨胀型阻燃剂组成的复配阻燃剂及常规挤出加工助剂,利用近熔点挤出理念及其加工设备,实现了分子量200万以上UHMWPE管材、板材制品的连续挤出。制品综合性能超过了2005年国家煤炭行业的技术标准,对提高行业技术水平、解决现实煤炭生产中的安全隐患、促进UHMWPE上下游产业的发展做出了贡献。
UHMWPE resin with a molecular weight of 3.8 million was used as the matrix resin, and a high content of conductive carbon black / polyethylene wax composite conductive agent, a complex flame retardant composed of a bromine-antimony system and an intumescent flame retardant, and Conventional extrusion processing aids, the use of nearly melting point extrusion concept and its processing equipment, to achieve a molecular weight of more than 2 million UHMWPE pipe, sheet products for continuous extrusion. The comprehensive performance of the products surpassed the technical standards of the national coal industry in 2005 and contributed to raising the technical level of the industry, solving potential safety problems in coal production and promoting the development of upstream and downstream UHMWPE industries.
