Description

Produce sealing impregnation pultrusion system and device and the preparation method of optical cable strengthening core

Technical field

The present invention relates to the device and method of optical cable strengthening core, be specifically related to the sealing impregnation pultrusion system and device and the preparation method that produce optical cable strengthening core.

Background technology

In order to strengthen the hot strength of communication cable, optical cable inside is all provided with reinforcement core.Figure 1 shows that existing communication cable structure chart, optical cable inside is provided with five five core optical cables, five five core optical cable centers are provided with a strengthening core, the external diameter of five core optical cables is coated with a circle Loose tube, sleeve pipe filler is connected with between optical cable and optical cable, cable core filler is connected with between Loose tube and Loose tube, coatedly on cable core filler external diameter be connected with a circle plastic-coated steel band, coatedly on plastic-coated steel band external diameter be connected with a circle pe sheath, past generally adopts steel wire as the reinforcement core of optical cable, but because steel wire exists corrosion-resistant, general use 1-2 will corrosion, and produce pernicious gas, cause hydrogen loss, affect Optical Fiber Transmission performance.In addition, because steel wire has electric conductivity, under high-tension electricity and effects of lightning, can induced-current be produced, performance and the signal transmission quality of optical cable can be affected.Therefore, there is the defect do not grown service life in this steel wire strengthening core

Along with the development of science and technology, the traditional alkali-free glass fibre silk of a kind of employing, dipping vinylite, solidified by mould heated resin, continuous pultrude process is adopted to produce composite material optical cable strengthening core, Fig. 2, Figure 3 shows that FRP or KFRP pultrude process, instead of steel wire becomes novel optical cable strengthening core as reinforcement core.The equipment and process adopted is open steeping vat, existing manufacturer production FRP or KFRP optical cable strengthening core, and the resin-based selected is vinylite and a small amount of curing agent and promoter (BPO-TBPB).And in vinylite styrene-content greatly about about 30%-40%.

As everyone knows, open steeping vat, if styrene is exposed among air polymerization and oxidation can occur gradually.Exist health and environmental hazard very large, water body, soil and air are polluted simultaneously.If meet naked light, high temperature or oxidising agent, have and cause combustion explosion dangerous, have stimulation and anesthetic effect to the eyes of human body and respiratory mucosa.If labourer protects improper, then can cause headache, weak, vomiting, anorexia, abdominal distension, melancholy, forgetful, refer to quiver.Long Term Contact, sometimes also causes obstructive lung pathology, pachylosis to ftracture and the defect such as to thicken.

In order to overcome the deficiencies in the prior art, technical scheme of the present invention solves like this: the sealing impregnation pultrusion system and device producing optical cable strengthening core is made up of fibre glass roving creel arrangement apparatus, yarn guide, glue groove, preforming mould, hot briquetting mould, mechanical type draw-gear, closed reel garden device, improvements of the present invention are that on the right side of described yarn guide, interval arranges an infrared heating moisture discharge device, on the right side of heating moisture discharge device, interval arranges a sealing load gumming device, a transparent sealing storage glue tank upper end is connected with glue-feeder with pipeline by 1# valve, described transparent sealing storage glue tank lower end is connected with sealing load gumming device with pipeline by 2# valve, the bottom of described sealing load gumming device is connected with binder removal mouth with pipeline by 3# valve, the terminal part of described sealing load gumming device is connected with vacuum pumping pump with pipeline by 4# valve, on the right side of the terminal part of described sealing load gumming device, interval arranges a hot briquetting mould, the optical cable strengthening core of hot briquetting is drawn to closed reel garden device by mechanical type draw-gear.

Described sealing impregnation pultrusion system and device produces a preparation method for optical cable strengthening core, carries out in the steps below:

(1), product specification on demand selects arrangement glass fibre or aramid fiber;

(2), open infrared heating moisture discharge device, dry glass fibre or aramid fiber with 150 DEG C ~ 200 DEG C;

(3), hot briquetting mould is opened, with 120 DEG C ~ 150 DEG C heating moulds;

(4), open 1# valve, the vinylite sizing material crossed by vacuum stirring is put into transparent sealing storage glue tank after closedown 2# valve;

(5), mold temperature to be heated starts to sealing load gumming device injecting glue after being raised to the technological temperature of setting; Step is: close 2# valve, 3# valve, and open vacuum pump evacuation and open 4# valve, vacuum is 0.8-1 MPa, closes 4# valve after the vacuum of setting to be achieved;

(6), open 2# valve, treat that sealing load gumming device piled by vinylite sizing material;

(7), by the hauling speed of technique initialization draw-gear is opened, by optical cable strengthening core traction to closed reel garden device;

(8), optical cable strengthening core pultrusion complete one circulation after, in sealing load gumming device remaining vinyl sizing material by the 3rd valve (3) get rid of.

(9), in whole production process, can add at any time if transparent sealing glue tank glue declines.

The present invention compared with prior art, has structure simple, easy to use, pollution-free to air, to the feature of workman's health fanout free region, containing cinnamic resin sizing material completely in the device of a sealing.The optical cable strengthening core product corrosion resistance produced is strong, can not get rusty, can not cause hydrogen loss, can not affect the signal propagation performance of optical fiber, insensitive to electric shock, is applicable to the climatic environment areas such as many thunders and lightnings are rainy, can adjacent power line and supply unit install.The induction power supply do not produced by it disturbs, and compared with metal-cored, it also has intensity high, lightweight.Therefore optical cable strengthening core long service life, the excellent properties such as product air-gap-free, density are large, intensity is high, are widely used in fiber optic cable communications manufacturing.
