Description
The invention belongs to the high temperature resistant communication cable that do not burn of a kind of soft type.This cable is widely used in key departments such as warship, submarine, military base, commanding agency, field army's communication, skyscraper, bulk storage plant.
At present, the communication cable of manufacturing all is that employing plastics or rubber are insulating material both at home and abroad, allows working temperature to be no more than 50 ℃.Along with society advances and the needs of economic construction, communication cable also requires to have high temperature resistant incombustible performance, and the whole communication system of the fire condition work as usual that can guarantee to meet accident of this communication cable ensures that communication is unblocked.
The objective of the invention is to design the high temperature resistant communication cable that do not burn of a kind of soft type.Make its have fire-retardant, do not prolong combustion, meet fire and do not burn, when the outside applied burning things which may cause a fire disaster, communication cable can be worked as usual, but continuous operation 18,000 hours under 600 ℃ of hot conditionss, long-term safety reliably working under 400 ℃ of temperature conditions.Not spontaneous combustion of this cable itself, initiation fire not.Thereby solved skyscraper, historical relic's protection, currency financial institution, military base, commanding agency and warship, submarine and field army and in unexpected fire incident or in the flames of war, guaranteed the communication operate as normal.Soft type of the present invention is high temperature resistant the do not burn core material of communication cable uses the bare copper wire of diameter 0.2～1.0mm.It is inner core coating, oversheath coating that technical characterictic of the present invention is to use the high temperature resistant coating that do not burn of two kinds of uniquenesses.Adopt three kinds of inorganic insulating materials: alkali-free glass fibre, quartz glass fibre, organosilicon little-glue single-face glass dust mica tape.Wherein inner core coating is made up of bisphenol A modified organic siliconresin, superfine talcum powder, 6101# resin, silane coupler KH550; Oversheath coating is made up of the poly-hydroquinones resin of organic silicon-boron, superfine talcum powder, silane coupler KH550,618# resin, chlorinated biphenyl ether.
Inner core formulation for coating material and preparation: bisphenol A modified organic siliconresin 70～90%, superfine talcum powder 8～20%, 6101# resin 1～5%, silane coupler KH550 1～5%, stir at normal temperatures and pressures, remove bubble.
Oversheath formulation for coating material and preparation: organic silicon-boron gathers hydroquinones resin 50～80%, superfine talcum powder 15～38%, silane coupler KH550 1～3%, 618# resin 1～3%, chlorinated biphenyl ether 3～5%, stir at normal temperatures and pressures, remove bubble.
In inner core coating and oversheath coating, can add 30～50% redness 5370, or yellow 5115, or green 5630, or blue look 5250, or orange 5420 match colors, can make multiple color-coded coating, to satisfy needs to multicore cable identification heart yearn.
The technological process of production of the present invention is:
1. wrapped organosilicon little-glue single-face glass dust mica tape: bare copper wire installed to be coated with on unit, carry out wrapped one deck organosilicon little-glue single-face glass dust mica tape, and unload;
2. weave alkali-free glass fibre or quartz glass fibre sheath: above-mentioned core with 8 word braiding machines braiding one deck alkali-free glass fibre or quartz glass fibre, is unloaded;
3. dip-coating inner core coating: the above-mentioned heart yearn that has woven oversheath is put into heart yearn coatings tank dip-coating heart yearn coating;
4. baking and curing: the heart yearn that dip-coating is good is put into drying oven and is carried out baking and curing (furnace temperature is 150～450 ℃, 5～25 seconds time), single core cable.
5. the making of multicore communication cable:
A. stranded stranding: above-mentioned single-core cable number to installing to stranding on the cabler, is unloaded;
B. wrapped organosilicon little-glue single-face glass dust mica tape: above-mentioned cable loaded onto be coated with around unit, carry out 2～4 layers of wrapped organosilicon little-glue single-face glass dust mica tapes, every circle is advisable to put up 1/3rd bandwidth;
C. wrapped metal tape screen:, unload with the above-mentioned wrapped layer of metal band of the cable screen that has wound mica tape;
D. weave alkali-free glass fibre or quartz glass fibre: will wind the cable of metal tape shielding, the oversheath with 8 word braiding machines braiding one deck alkali-free glass fibre or quartz glass fibre unloads;
E. dip-coating oversheath coating: the above-mentioned cable that has woven oversheath is put into oversheath coatings tank dip-coating oversheath coating;
F. baking and curing: the cable of the good oversheath coating of dip-coating is put into the drying oven baking and curing, 350～900 ℃ of furnace temperature, 10～30 seconds time, the multicore communication cable.
The present invention can increase and decrease suitably as required that each is wrapped, braiding level and built-up sequence, produces the high temperature resistant communication cable that do not burn of soft type of making multiple performance, comprises two cores platypelloid type telephone wire arranged side by side.
Advantage of the present invention and technical indicator are: this communication cable is met naked light and is not burnt, and keeps operate as normal, and not spontaneous combustion of cable itself has fire-retardant, as not prolong combustion characteristic.But continuous operation is 18,000 hours under-65～600 ℃ of conditions, can work reliably and with long-term under-60～400 ℃ of conditions.In the time of-60 ℃ this cable jacket do not chap, non-scale.This cable normal temperature softness, bending radius are 5 times of the outside diameter of cable, can manufacture the high temperature resistant communication cable that do not burn of soft type of 10～400 pairs of random lengths.
