Tightening pipe hoop for plastic pipeline connection

The invention discloses a tightening pipe hoop for plastic pipeline connection. The tightening pipe hoop is prepared from the following raw materials in percentage by weight: 96.6 to 98.6 percent of HDPE (High-Density Polyethylene), 0.3 to 0.5 percent of main antioxidant, 0.1 to 0.3 percent of auxiliary antioxidant, 0.3 to 0.7 percent of cross-linking agent A, 0.2 to 0.4 percent of assistant cross-linking agent and 0.5 to 1.5 percent of nanoscale filler, the nanoscale filler comprises silicate, calcium carbonate, oxide or a mixture thereof. The crosslinking degree of the plastic pipeline connection tightening pipe hoop is larger than 80%, the plastic pipeline connection tightening pipe hoop has good temperature resistance and creep resistance and is qualified through a thermal stability test (GB/T18992.2-2018) in a hydrostatic state, and the retraction force of the manufactured dn20 tightening pipe hoop can reach 27.6 Mpa. 本发明公开了一种用于塑料管道连接的紧缩管箍，其由以下重量百分比组分组成的原料制成：HDPE 96.6～98.6，主抗氧剂0.3～0.5，辅助抗氧剂0.1～0.3，交联剂A 0
