Description of drawings
Fig. 1 is the cross section structure synoptic diagram of high temperature resistant radiation resistant optical fiber of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail:
With reference to shown in Figure 1, high temperature resistant radiation resistant optical fiber of the present invention, comprise fibre core 1 and covering 2, covering 2 outsides are provided with sputter coating layer 31, sputter coating layer 31 external electric are coated with electroplates rete 32, and, sputter coating layer 31 and the plating rete 32 common coats that constitute high temperature resistant radiation resistant optical fiber of the present invention.Wherein, high temperature resistant, radiation-resistant sputter aluminizer, sputter copper plating film, sputter plated nickel film, sputter chromium plating film or the sputter gold-plated film etc. of sputter coating layer 31 for having certain intensity and flexibility.Be similarly high temperature resistant, radiation-resistant aluminium coated, copper plate, nickel coating, chromium coating, Gold plated Layer, cobalt plating layer or lead plating layer etc. and electroplate rete 32 with certain intensity and flexibility.In addition, in order to satisfy the needs of different fields of employment, the number of plies of sputter coating layer 31 and thickness can suitably increase and decrease, and to reach better high temperature resistant, radiation proof effect, the place for example higher in temperature, that radiation is stronger can suitably increase the number of plies or the thickness of sputter coating layer 31.
High temperature resistant radiation resistant optical fiber of the present invention can adopt following processing technology:
The naked fibre of step 1, the no coat of preparation.The naked fibre of the no coat of preparation has two kinds of methods: the one, adopt finished product optical fiber, after the coat that immersion a period of time constitutes macromolecular materials such as its acrylate by ultra-violet curing, polyimide in acetone is softening, method artificial or its coat of mechanical stripping obtains, but the suitable usually preparation length of this method is less than 3 meters naked fibre.The 2nd, direct drawing prepares the naked fibre of length greater than 3 meters no coat if desired, can adopt the method for direct drawing.
The naked fibre that step 2, cleaning previous step obtain.Because optical fiber surface often speckles with organism such as fingerprint, greasy dirt, and the inorganicss such as dust that depend on electrostatic interaction to adhere to, these dirts all should be removed.The alkaline reagent that is usually used in oil removing has silicate and phosphate two classes, but they may form film on naked fine surface, follow-up etch are handled influential concrete.Therefore, the processing technology of this present embodiment adopts following steps to clean:
At first, the surface of not having the naked fibre of coat with the even wiping of cotton ball soaked in alcohol.
Secondly, naked fine the immersion in the NaOH solution that concentration is 100g/L of wiping soaked about 10 minutes, can suitably increase the concentration of NaOH solution when greasy dirt more for a long time.
At last, from NaOH solution, take out naked fibre and rinse well with deionized water.
Step 3, the naked fibre that obtains after will cleaning are put into coarsening solution and were soaked 10 minutes.So-called alligatoring had both adopted strong oxidizer or coarsening solutions such as strong acid, highly basic that naked fibre is carried out chemical treatment, and the surface is selectively dissolved, and produced rough point of fixity, to improve the tack of coating.The coarsening solution that present embodiment is selected for use is: HF: H2SiF6: H2O=1: 1: 2 (volume ratio), coarsening time are 10 minutes.
Step 4, the naked fibre that previous step is obtained carry out activation processing.Activation claims thermal treatment again, the residual moisture film that is the bare wire surface that will obtain after the alligatoring is removed, make that the adhesion on coatings and bare wire surface is stronger, the condition of the thermal activation treatment of present embodiment is: naked fibre is insulation 10 minutes in 120 ℃ the insulation can at design temperature.
The magnetron sputtering stove that step 5, the naked fibre that previous step is obtained are sent into band circumference rotary sputtering target carries out sputter coating to be handled.Naked fibre will keep certain force of strain in carrying out the sputter coating processing procedure, so just can realize the sputter coating of the continuous naked fibre of certain-length.In order to make naked fine circumferential surface sputter even, require rotary sputtering target to center on naked fibre and make uniform circular motion.As long as this motion is uniform rotation, just can realize that naked fine circumferential surface coating is even.And the axial homogeneity of naked fibre will be leaned at the uniform velocity the guaranteeing of retractable cable of naked fibre.
Step 6, the optical fiber that previous step is obtained carry out electroplating processes.
Because the metal material high temperature performance is far superior to macromolecular material, and can well shield irradiation.Therefore, substitute the optical fiber of macromolecule coat with the washing layer, have high temperature resistant, anti-irradiation and corrosion resistant advantage, optical fiber can be operated in the unusual rugged environment, substantially can not increase the volume and weight of optical fiber again, thereby improve optical fiber properties, enlarge the temperature working range of optical fiber, improve the serviceable life of optical fiber, reduced cost.Simultaneously, because the washing layer is compared with the macromolecule coat, have better sealing property and decay resistance.It also has corrosion-resistant, and anti-seawater, and the characteristic of oxidation resistant ability and sealing are so can also can be used for Underwater Battery equipments such as fibre optic hydrophone, wireguided torpedo by high temperature resistant radiation resistant optical fiber of the present invention.
Above embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
