Abstract

The invention discloses a formula of a modified polytetrafluoroethylene-ethylene copolymer. The formula comprises a polytetrafluoroethylene-ethylene copolymer and additives, the additives comprises a light stabilizer, a filler, a tackifier, a coupling agent and a cross-linking agent, the light stabilizer is ethyl 2-cyan-3,3-diphenylacrylate, the filler is glass fibers, the tackifier is polyvinyl acetal, the cross-linking agent is 2.5-dimethyl-2,5-di-tery-butylperoxyhexane, and the coupling agent is methacryloxypropyltrimethoxysilane. The formula allows the prepared modified polytetrafluoroethylene-ethylene copolymer to have the characteristics of good fluidity, high mechanical and physical performances, radiation resistance, good viscosity, stable product performances, low production cost and the like.

Description

technical field [0001] The invention relates to a plastic formulation, in particular to a formulation of a modified polytetrafluoroethylene-ethylene copolymer. Background technique [0002] PTFE-ethylene copolymer has excellent chemical corrosion resistance, corrosion resistance to all chemicals, the lowest coefficient of friction among plastics, and good electrical properties. Its electrical insulation is not affected by temperature. "King of Plastics". However, polytetrafluoroethylene-ethylene copolymer has poor fluidity, is easily decomposed, and generates corrosive gas when decomposed. The adhesion of PTFE-ethylene copolymer is extremely poor, and the practical range is relatively limited. At the same time, the manufacturing cost in the production process is relatively high, and the performance of the produced product is unstable. Contents of the invention [0003] The purpose of the present invention is to provide a modified polytetrafluoroethylene-ethylene copolym...
