Abstract

The invention relates to an antistatic halogen-free fire-retardant super high molecular weight polythene composition. The weight portions of the compositions of the composition are as follows: 50 portions to 85 portions of super high molecular weight polythene, 5 portions to 30 portions of ammonium polyphosphate, 2 portions to 20 portions of melamine and derivatives thereof, 2 portions to 30 portions of polyhydroxy compound, 0.5 portion to 20 portions of phosphonate, 0.5 portion to 20 portions of encapsulated red phosphorus, 0.1 portion to 10 portions of antistatic agent, 0.1 portion to 10 portions of flow modifier, 0.05 portion to 10 portions of dispersant, 0.03portion to 5 portions of coupling agent and 0.02 portion to 5 portions of antioxidant. The composition does not contain halogen, has good fire retardancy and antistatic performance, and does not affect characteristics of the super high molecular weight polythene, i.e., good wearing resistance, anti-aging property and anti-corrosion performance. The composition can meet the needs of products replacing steel with plastics from various aspects.

Description

technical field [0001] The invention relates to the fields of halogen-free flame retardants and polymer modification processing, in particular to an antistatic halogen-free flame-retardant ultra-high molecular weight polyethylene composition. Background technique [0002] The high molecular weight characteristics of ultra-high molecular weight polyethylene (UHMWPE) materials make it have good wear resistance, high impact strength, self-lubricating and non-adhesive, which are incomparable to ordinary polyethylene and other engineering plastics. It has been widely used in the fields of textile, mining, chemical industry, packaging, machinery, construction, electrical, medical, sports, etc. At the same time, it has also been widely used in the fields of nuclear energy and weapons. However, in some applications with special requirements, the application of UHMWPE is limited. [0003] The volume resistivity of UHMWPE is very high, which is 1×10 17 ~1×10 18 Ω·cm, can be used as...
