Abstract

The invention provides a cross-linked rubber material, cross-linked fluororubber, a cable, a preparation method and application, and belongs to the technical field of rubber materials. The cross-linked rubber material comprises 100 parts of fluororubber, 3-7 parts of reinforcing filler, 20-50 parts of inorganic nano particles, 1-3 parts of a lubricant, 1.5-3.5 parts of a release agent, and 3-6 parts of a cross-linking agent. The molecular weight of the fluororubber is 300 to 500, and the fluorine content in the fluororubber is 30%-50%. The material has excellent high and low temperature resistance of fluoroplastic, also has flexible oil resistance, acid and alkali resistance of a rubber material, and has better heat resistance, oil resistance, acid and alkali resistance and mechanical properties through irradiation crosslinking of an electron accelerator. The cable material can be widely applied to confidential instruments and meters, household appliances, medical equipment, mechanical equipment, communication equipment, marine cables and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to cross-linked rubber materials, cross-linked fluorine rubber and cables, preparation methods and applications. Background technique [0002] With the development of the modern automobile industry, the structure is getting tighter and tighter, safety requirements are put in the first place, and the requirements for cables are getting higher and higher, requiring ultra-thin walls, high temperature and low temperature resistance, solvent resistance and oil resistance, high wear resistance, flame retardancy, etc. [0003] Most of the existing rubber materials have low tensile strength, poor tear resistance, poor resistance to alcohol esters or aromatic solvents, poor acid and alkali resistance to gasoline and mineral oil, and poor resistance to high temperature steam; because Some disadvantages of existing rubber materials, existing rubber cables are relatively li...
