Description

The silicone pipes that a kind of fire resistance is good
Technical field
The present invention relates to silicone pipes technical field, particularly relate to the silicone pipes that a kind of fire resistance is good.
Background technology
21 century is the epoch of information, and with fastest developing speed is information industry, and in the transmission of information, optical cable is most important logical Road, because only that optical cable can transmit substantial amounts of information with the fastest speed, also will not be disturbed, will not give away secrets, and China is the most several Year telecommunication cause develop the stages of historical development having had passed over from cable communication to optical cable rapidly, from civilian to military, from Phone all enters optical-fibre communications epoch, the biggest development having promoted plastic optical fiber cable jacket ducts to multimedia.Light Cable is typically buried in underground, for being effectively protected optical cable, generally adds a protection sleeve pipe outside optical cable, in cable run process In, the tubing used at first is steel pipe, pipe of cement, pvc pipe and double-wall corrugated pipe, and the problem using middle maximum is how to solve to wear The lubrication problem of inner-walls of duct in cable, typically uses the way of coating lubricant by aforementioned tubes, i.e. before wearing cable first when constructing The lubricant of liquid is coated in pipe material inner wall, but due to the effect of gravity, makes lubricant can not be uniformly distributed in pipe material inner wall, And the cable being also dried by leading portion when wearing cable takes away, therefore no matter select drawing method when wearing cable or blow afloat method, lubrication Problem all directly affects length and the speed wearing cable, uses these methods all to considerably increase the artificial and increase of resource expense. Silicone pipes friction factor is less, and pipe joint is few, quick construction, be not required to outer increasing protection of pipe, greatly reduces construction costs, due to Inwall silicon core layer is permanent solid lubrication oxidant layer, and frictional behaviour keeps constant, and cable can extract in pipe repeatedly, will not shell Falling, depart from, ageing-resistant service life was up to more than 50 years, so silicon core cable tube is widely used in a variety of applications.
Studying more person in silicone oil grease is methyl-silicone oil grease, due to the thickening poor-performing of dimethicone, The compatibility with organic material is the poorest, so, there is the problems such as greasy property is not good enough in methyl-silicone oil grease, limits its application Scope." alkyl modified silicon oil preparation of greases and performance study " Wen Zhongzhu state builds employing containing hydrogen silicone oil and linear alpha olefin Carry out hydrosilylation, prepare alkyl modified silicon oil, then itself and 12 hydroxy stearic acids are carried out saponification, prepare alkyl Modified silicon oil grease, result shows that, under close viscosity, the film strength of alkyl modified silicon oil is bigger than methyl-silicone oil, lubrication Property more preferable, the refractive index ratio methyl-silicone oil of alkyl modified silicon oil is high, closer to Dormant oils, fat and Organic substance, compatible with them Property more preferable, the transparency is higher, but sintering load is close with methyl-silicone oil, not raising, and weatherability, oxidative resistance and resistance to The characteristics such as solvent are general, reduce use field, in order to enable silicone oil grease well to be utilized in silicone pipes, this It is expanded modification by invention on its basis, makes the silicone pipes of preparation disclosure satisfy that the nowadays optical fiber requirement to silicone pipes, actively Accomplish to reduce cost, economize on resources and protect environment.
