Abstract

The invention relates to a fluoroelastomer heat-shrinkable tube and a manufacturing method thereof. In order to overcome the defects that a traditional heat-shrinkable tube has poorer performance on resisting temperature, oil and solvents and cannot adapt to high performance requirements on resisting the oil and the solvents in industries of automobiles, high-speed trains, war industry, aerospaceand the like, the invention provides the fluoroelastomer heat-shrinkable tube which mainly comprises the materials of a fluoroelastomer, a fluorine resin acid acceptor, a reinforcing agent and a plasticizer. Meanwhile, the invention also provides a method for manufacturing the heat-shrinkable tube by using the materials. The fluoroelastomer heat-shrinkable tube provided by the invention can be applied to the industries of automobiles, high-speed trains, war industry, aerospace and the like which have higher requirements for resisting high and low temperature and the solvents.

Description

technical field

[0001] The invention relates to a heat-shrinkable tube, in particular to a fluoroelastomer heat-shrinkable tube and a manufacturing method thereof. Background technique

[0002] At present, the main materials used to produce heat-shrinkable tubing include: ① olefin polymers or copolymers; ② rubber-like materials or thermoplastic elastomers styrene-butadiene-styrene block copolymer (SBS), styrene - One or more materials in the isoprene block copolymer (SIS); ③ other auxiliary materials. Although the existing heat-shrinkable tubes have good flame retardancy and environmental protection performance, they are relatively poor in temperature resistance, oil resistance and solvent resistance, and cannot adapt to high oil resistance and solvent resistance in automobiles, high-speed trains, military and aerospace industries. requirements. Contents of the invention

[0003] In order to overcome the problem that the existing heat-shrinkable tubes have relatively poo...
