Zusammenfassung: | The invention belongs to the technical field of heat-shrinkable tube manufacturing, and particularly relates to a fluoroelastomer heat-shrinkable hose material for new energy flexible connection and a preparation method of the fluoroelastomer heat-shrinkable hose material. The fluoroelastomer heat-shrinkable hose material for the new energy flexible connection is prepared from the following raw materials in parts by mass: 50 to 80 parts of vinylidene fluoride-hexafluoropropylene copolymer, 10 to 30 parts of fluororubber, 3 to 20 parts of filling agent, 2.5 to 10 parts of anti-sticking agent and 0.5 to 2.5 parts of lubricating agent, wherein the melt viscosity of the vinylidene fluoride-hexafluoropropylene copolymer, when measured at 230 DEG C and at a shear rate of 100 s , ranges from 10 kPoise to 30 kPoise; the shore hardness of the vinylidene fluoride-hexafluoropropylene copolymer is 30 to 50D. When the fluoroelastomer heat-shrinkable hose material is applied to new energy flexible connection, the fluo |
