Abstract
A synthetic fiber reinforced core of an optical cable relates to a high-performance non-metal reinforced material which comprises a core layer formed by mixing common glass fiber and high-strength fiber; and a thermosetting resin layer is dipped outside the core layer. The reinforced core has the following advantages that firstly, the core layer of the reinforced core is formed by mixing the common glass fiber and the high-strength fiber, so that the reinforced core has good strength and anti-gnawing performance due to the high-strength fiber, and has good cost performance due to mixture of two types of materials; secondly, the reinforced core made of non-metal has good corrosion resistance; and thirdly, meanwhile, compared with the reinforced core made of metal, the reinforced core has the advantages of light weight, easy transportation, low transportation cost and the like, and avoids the risk of line collapse caused by the excessive weight of the optical cable in severe weather such as rain, snow, sleet and the like due to the advantage of light weight, thereby ensuring the safety of a transmission line and further guaranteeing people's ordered daily life.
Description
Technical field
The utility model relates to a kind of high performance nonmetal reinforcing material, can be used in various communication cables, power cable and the optical fiber cable as reinforcing material.
Background technology
In order to improve the serviceable life of optical cable, satisfy it and adapt to various environment, when particularly using, its intensity, corrosion resistance and the anti-performance of nibbling have been proposed higher requirement in the open air, so in optical cable, be provided with strengthening core, make it can satisfy various request for utilizations; Traditional strengthening core is made of metal, the general iron that adopts is made, have following shortcoming: 1) its weight is heavier, poor mobility, the landed cost height, and when inclement weathers such as barber, hail, can cause collapsing of transmission line of electricity because optical cable is overweight, bring great inconvenience for people's trip and daily life, as the big snow disaster in 06 year was exactly an extraordinary example, and strengthening core occupies bigger weight in optical cable, so how to make strengthening core under the prerequisite that does not influence request for utilization, just should alleviate the weight of strengthening core as far as possible; When 2) metal strengthening core poor chemical stability, special lowered in field environment, corroded easily, used the effect that just is difficult to play strengthening core after a period of time, caused the optical cable reduction in serviceable life.The someone has used nonmetallic materials to make strengthening core for this reason, generally select the simple glass fiber specifically for use, as alkali-free glass fibre, though price is low, but its combination property is relatively poor, the occasion higher at ask for something can not reach request for utilization, as select high-intensity fiber for use, for example select high-strength glass fibre, carbon fiber, aramid fiber, basalt fibre etc. for use, though its good combination property can satisfy all-environment request for utilization, but its price is higher, in some environment occasion preferably, it is relatively poor that its cost performance just seems, influenced its marketable value.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of cost moderate, and has the composite fibre enhancing optical cable strengthening core of good combination property.
The technical solution of the utility model is: the utility model comprises the sandwich layer of being made up of simple glass fiber and high-intensity fiber mixing, and sandwich layer is impregnated with thermoset resin layer outward.
Further, described sandwich layer by simple glass fiber and high-intensity fiber by 3-7: 1 spinning forms.
Further, the cross section of described strengthening core is circular.
The utlity model has following advantage: 1) sandwich layer of strengthening core is made up of simple glass fiber and high-intensity fiber mixing, because the existence of high-intensity fiber makes it have good intensity and the anti-performance of nibbling; Two kinds of materials mix then makes it have good cost performance; 2) strengthening core of nonmetal system then makes it have excellent corrosion resisting performance; 3) compare the strengthening core that is made of metal simultaneously, has lightweight advantage, carrying easily, advantages such as transportation cost is low, moreover because it has lightweight advantage, when running into inclement weather such as sleet, hail, the danger that circuit collapses can not take place because optical cable is overweight, guarantee the safety of transmission line of electricity, ensure orderly the carrying out of people's daily life.
So strengthening core of the present utility model has been taken all factors into consideration the factor of each side, has good practicability.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that sandwich layer, 2 is thermoset resin layer among the figure.
Embodiment
The utility model comprises the sandwich layer of being made up of simple glass fiber and high-intensity fiber mixing 1, the sandwich layer 1 outer thermoset resin layer 2 that is impregnated with; Described sandwich layer 1 by simple glass fiber and high-intensity fiber by 3-7: 1 spinning forms; The cross section of described strengthening core is circular.
The utility model can be implemented according to following manner:
1, adding filler and the resin mixture of other auxiliary agent through fully mixing formation evenly add in the glue groove in the thermoset resin.
2, reinforcing material that mix to form of simple glass fiber and high-intensity fiber after yarn guide is drawn, enters a glue groove that resin mixture is housed from the creel.
3, after the resin mixture in the glue groove is fully soaked into reinforcing material, by a heating mould.
4, resin mixture and the reinforcing material typing that is cured by heating mould the time, the temperature of heating mould is controlled between the 140-210 degree, and is pulled out mould under the traction of external force, finally forms composite fibre and strengthens optical cable strengthening core.
The formula rate of the utility model each several part: simple glass fiber 60-70%, high-intensity fiber 10-20%, resin 15-20%, filler 0-5%.
Simple glass fiber of the present utility model can be selected alkali-free glass fibre for use, and fortifying fibre can be selected high-strength glass fibre, carbon fiber, aramid fiber, basalt fibre for use, and thermoset resin can be selected vinylite, epoxy resin for use.
In order to adapt to the application in optical cable, the cross section of the utility model strengthening core is circular, and diameter is generally between the 0.5-6mm.
After testing, the pulling strengrth of the utility model strengthening core is greater than 1500mpa, far above the pulling strengrth of the strengthening core of selecting for use the simple glass fiber to make fully.
