Abstract

The invention belongs to the field of cables, and discloses an aircraft engine cable material. The material comprises the following raw materials in parts by weight: 20-40 parts of fluororubber, 20-30 parts of ethylene propylene diene monomer, 5-15 parts of modified phenolic resin, 8-16 parts of a solubilizer, 2-6 parts of a vulcanizing agent, 10-20 parts of filler, 2-6 parts of polyurethane, 4-6 parts of a plasticizer, 1-3 parts of a stabilizer, 2-4 parts of a flame retardant, 1-2 parts of an anti-aging agent, 2-4 parts of a pretreatment enhancer, 5-7 parts of glass fiber and 1-2 parts of an antioxidant. According to the scheme, the aircraft engine cable material is prepared by adopting the blended rubber of the fluororubber and the ethylene propylene diene monomer through the synergistic cooperation of other raw materials and the combined action of all the steps, the aircraft engine cable material has excellent high-temperature resistance, high strength and the like, the modified phenolic resin has the bonding performance, the bonding force of all the components in the rubber material can be improved, thus the wear resistance and mechanical properties of the rubber material are enhanced. Meanwhile, the phenolic resin has relatively high high-temperature resistance, so that the high-temperature resistance of the cable material can be improved, and the preparation process is simple in procedure, the raw materials are easy to obtain, and the material is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aircraft engine cable material and a manufacturing method. Background technique [0002] The cable is mainly composed of the following four parts. Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be twisted by a single wire or multiple wires; insulation layer: the insulation material used for cables should have high insulation resistance and high breakdown electric field strength, low dielectric loss and low dielectric constant. Sealing sheath: protect the insulated wire core from mechanical damage, moisture, moisture, chemicals, light, etc. For moisture-prone insulation, lead or aluminum extruded sealing sheaths are generally used; protective covering: used to protect the sealing sheath from mechanical damage. [0003] The aircraft engine cable is a kin...
