Background
High temperature heating cables are used in civil and industrial fields to achieve heating or heat preservation effects. The high-temperature cable generally comprises an alloy or carbon fiber heating core wire, a flame-retardant high-temperature-resistant insulating layer, a high-temperature-resistant sheath (such as an aluminum foil layer), a shielding layer and an enameled wire from inside to outside; the flame-retardant high-temperature-resistant insulating layer wrapping the heating core wire is very critical to the performance influence of the high-temperature cable, and determines the heating temperature and the service life of the high-temperature cable. The existing flame-retardant high-temperature-resistant insulating layer generally adopts a silica gel layer, such as vinyl silicone rubber, and the silica gel has long service life and excellent ageing resistance at normal working temperature (180-200 ℃); however, when the heating temperature exceeds 200 ℃, the aging phenomenon of the silica gel is obvious, and the service life is rapidly reduced. Therefore, for a heating environment requiring a higher temperature, the current high-temperature cable using silicone rubber as a flame-retardant high-temperature-resistant insulating layer is not suitable, and a high-temperature cable flame-retardant high-temperature-resistant insulating layer having excellent aging resistance at a high temperature needs to be researched.

Preferably, the siloxane containing active hydrogen in the white carbon black reinforcing agent is one or more of tetramethylcyclotetrasiloxane, trifluoropropylmethylcyclotrisiloxane and tetramethyldisiloxane.
More preferably, the content of active hydrogen in the siloxane containing active hydrogen in the white carbon black reinforcing agent is 0.2-0.28% by mass.
More preferably, the white carbon black in the white carbon black reinforcing agent has a particle size of 10-40nm and a specific surface area of 200-300m2Fumed silica/g.
Preferably, the silane assistant comprises one or more of hydroxyl-terminated polydimethylsiloxane, dimethyl diethoxysilane and hydroxyl fluorosilicone oil.
According to another object of the invention, the high-temperature cable comprises a heating core wire, a flame-retardant high-temperature-resistant insulating layer, a high-temperature-resistant sheath, a shielding layer and an enameled wire layer from inside to outside, wherein the flame-retardant high-temperature-resistant insulating layer is the fluorosilicone rubber high-temperature-resistant layer.
Preferably, the heating core wire is made of alloy wires or carbon fibers.

Detailed Description
The features and advantages of the invention are described in detail below with reference to specific embodiments.
Compared with methyl vinyl silicone rubber, the fluorosilicone rubber has extremely excellent oil resistance, solvent resistance and chemical resistance; and the fluorosilicone rubber has little performance change under the harsh conditions of high temperature, low temperature, humidity, oil, solvent, chemicals, ozone and the like. However, since the pure fluorosilicone rubber is greatly affected by temperature, it is necessary to add a reinforcing agent, a rare earth filler, and the like to the fluorosilicone rubber to ensure that the fluorosilicone rubber has relatively high heat resistance.
Specifically, according to an embodiment of the present invention, a fluorosilicone rubber high temperature resistant layer applied to a high temperature cable is prepared by mixing the following raw materials in parts by weight: 100 parts of silicon rubber; 38-43 parts of white carbon black reinforcing agent; 9-11.6 parts of a silane assistant; 2-3.5 parts of cerium oxide filler; 0.10-0.18 part of lubricant and 0.5-1.5 parts of vulcanizing agent; the silicone rubber is a mixture of raw methyl vinyl silicone rubber and raw fluorosilicone rubber in a weight ratio of 6:94, wherein the vinyl content of the raw methyl vinyl silicone rubber is 0.25-0.35%, and the vinyl content of the raw fluorosilicone rubber is 0.4-0.8%; the white carbon black reinforcing agent is formed by mixing white carbon black and siloxane containing active hydrogen according to the weight part of 100: 10-18; the vulcanizing agent is one or more of dicumyl peroxide, 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane and tert-butyl peroxybenzoate.
In order to ensure the temperature resistance of the fluorosilicone rubber at high temperature, the oxide of the rare earth element cerium is added into the fluorosilicone rubber as a filler, and experiments prove that the performance stability of the fluorosilicone rubber at high temperature can be ensured when the mass part of cerium oxide in the fluorosilicone rubber reaches a certain degree, for example, in a preferred embodiment, when the mass part of cerium oxide reaches about 3, the fluorosilicone rubber still has good performance stability at high temperature about 350 ℃; when the mass fraction of the cerium oxide exceeds 3.5, the effect of the cerium oxide particles as impurity defects in the fluorine-containing silicone rubber matrix is obviously embodied, the thermal degradation of the rubber is very obvious, and the cerium oxide particles can be rapidly explained and fail at the temperature of over 400 ℃.
In addition, according to experiments, the white carbon black and siloxane are adopted as the reinforcing agent of the fluorosilicone rubber, so that the mechanical property of the fluorosilicone rubber can be obviously improved, the viscosity is reduced, and the processing performance of the fluorosilicone rubber is improved; in addition, the content of active hydrogen in the siloxane has a relatively obvious influence on the tensile strength of the fluorosilicone rubber within a certain range, in a more preferred embodiment, the content of the active hydrogen in the siloxane containing the active hydrogen in the white carbon black reinforcing agent is 0.2-0.28% by mass, and when the content of the active hydrogen exceeds 0.3% by mass, the influence on the performance of the fluorosilicone rubber is relatively insignificant.
In another preferred embodiment, the silica white in the silica white reinforcing agent has a particle size of 10-40nm and a specific surface area of 200-300m2The excessive particle size of the fumed silica/g can obviously reflect the function of impurity defects in the fluorine silicon rubber matrix, and the rubber performance is influenced.
In another preferred embodiment, the silane adjuvant comprises one or more of hydroxyl-terminated polydimethylsiloxane, dimethyldiethoxysilane and hydroxyl fluorosilicone oil.
The vulcanizing agent of the fluorosilicone rubber adopts one or more of dicumyl peroxide, 2, 5-dimethyl-2, 5-di (tert-butylperoxy) hexane and tert-butyl peroxybenzoate with higher activity, so that the adverse effect of the vulcanizing agent on the crosslinking density of the rubber is reduced.
According to the high-temperature-resistant and anti-aging high-temperature-resistant cable fluorosilicone rubber high-temperature-resistant layer, the excellent anti-aging performance of fluorosilicone rubber is utilized, the white carbon black reinforcing agent and a proper amount of cerium oxide filling agent are adopted to improve the high-temperature-resistant performance of the high-temperature-resistant layer fluorosilicone rubber, so that a high-temperature cable still has excellent heat resistance and long service life at the temperature of more than 300 ℃, and the high-temperature cable is adapted to a more severe use environment.
The present invention is not limited to the embodiments described above, and those skilled in the art may make modifications or changes within the scope of the disclosure without departing from the spirit of the present invention, so that the scope of the present invention is defined by the appended claims.
