Background technique
Fluorubber refers to the macromolecular elastomer that fluorine atom is connected on the carbon atom of molecular backbone or side chain.In fluorubber point
In minor structure, greatly, and fluorine atom covalent radius (0.064nm) is equivalent to C-C key key to the bond energy (435~485kJ/mol) of C-F key
Long half, C-C segment are protected well by fluorine atom, and therefore, fluorubber has the chemical stability of height and heat steady
It is qualitative, it is one kind that medium-resistance is best in current all elastic body, can be widely used for aerospace, automobile, machinery, petrochemical industry
Deng.
The high-temperature brake hose of usual automobile inflator pump connection needs high temperature resistant to 200 DEG C and -40 DEG C of low temperature, while wanting resistance to
Compressor oil and a small amount of water, vapor, and withstand 1.5MPa long-time service pressure below.Since automobile is in various complexity
Road conditions downward driving, the vibration of different frequency occurs, so hose needs very strong shock resistance.Generally also have using stainless steel
Bellows, ethylene propylene diene rubber braided steel wire pipe, polytetrafluoroethylene (PTFE) ripple steel wire woven tube etc.；But corrugated stainless steel tubing connects
Head weld is too thin, and under high-frequency vibration, solder joint is easy to crack, and accident rate is very high；The resistance to height of ethylene propylene diene rubber woven tube
Temperature is excessively poor, can only be to 150 DEG C, and compression resistant machine oil is excessively poor, so being easy to aging embrittlement in；Polytetrafluoroethylene (PTFE)
Ripple woven tube is since creep is very big, and especially high-temerature creep is more severe, so just will appear leakage after a period of use very
To the situation of de- head.
The automobile-used high temperature fluorubber air-brake coupling hose of Zhejiang iron-clad horses tubulation Co., Ltd application, the patent No. 200420036301.1
In, using fluorubber inner tube, outer volume steel wire by cutting ferrule, connector, is formed connected nut, and cutting ferrule and connector are connected in a manner of pressure by clamping
It connects.The technology uses general fluorubber, and hot tear crack is poor under high temperature；Simultaneously as being connected using pincers pressure mode, connect at high temperature

In 200410030386.7, magnesia, calcium hydroxide, carbon black, vulcanizing agent are equipped with using the raw rubber of vinylidene and hexafluoropropene
It is realized Deng the techniques such as steel core, primary and secondary vulcanization, customized cut-off are placed by mixing, slice, extrusion.It must be in the technology
Steel core is put in pipe, there are operating difficulties, tube lengths to be limited, and scraps the defects such as high, stress levels are low, and not to the pipe
Connection type is explained, if using pincers pressure etc. mechanical compression mode, the material there are under high temperature compression cracking and it is low temperature resistant
The problem of being not achieved 40 DEG C, it is difficult to guarantee that automobile high-temperature brake is flexible coupling using safe.
