Abstract
The utility model discloses an FFRP rod used for optical cables. The FFRP rod is formed by a plurality of fiber and an adhesive, wherein the plurality of fiber are arranged in the adhesive; the plurality of fiber and the adhesive form a cylinder in the length direction; the diameter of the cylinder is between 0.3mm and 10mm; and during the processing of the optical cables, the FFRP rod plays the roles of strengthening and side compression resisting. The FFRP rod replaces a steel wire and avoids the problem of iron oxidation and hydrogen evolution; and the FFRP rod can prevent lightening when being used in lightning strike zones and overcomes the fatal flaw that a common FRP rod breaks easily when the bevelling radius is small.
Description
Technical field
The utility model relates to physics and chemical field, relates in particular to optical cable, particularly a kind of optical cable FFRP bar.
Background technology
In the prior art, the reinforcement of optical cable adopts the tubular FRP (glass fiber reinforced plastics) of steel wire or rigidity usually.But steel wire is during as reinforcement, and its optical cable can only be used for outdoor and can not be used for indoor; The tubular FRP bending radius of rigidity can fracture when too small, and optical cable often need be converted into 90 ° when indoor laying.
Summary of the invention
The purpose of this utility model is to provide a kind of optical cable FFRP bar, and described this optical cable will solve the technical matters that inside cable fractures easily in the prior art with the FFRP bar.
This optical cable of the present utility model is made of complex root fiber and tackifier with the FFRP bar, described complex root fiber is arranged in the described tackifier, wherein, described complex root fiber and described tackifier constitute a right cylinder, described right cylinder extends vertically, and cylindrical diameter is between 0.3mm～10mm.
Further, the rounded or sub-circular of described cylindrical radial section.
Further, the bearing of trend of described complex root fiber is identical with described cylindrical bearing of trend.
Further, described complex root fiber evenly or periodically is distributed in the described tackifier.
Further, described complex root fiber is glass fibre or fragrant human relations or the fiber of carbon fiber or other high strength low elongation or their potpourri.
Further, described tackifier is inorganic adhesive or organic adhesion agent, or natural adhesive or synthetic adhesive, or resin adhesive or rubber adhesive or compound tackifier, or thermoplastic adhesive or hot setting adhesive or hot melt adhesive, or the potpourri of above-mentioned two or more tackifier.
Further, described hot setting adhesive is phenolics or Lauxite or melamine formaldehyde resin or epoxy resin or acryl resin or polyimide or polyurethane, or two or more potpourri wherein.
Further, the quantity of described complex root fiber is at least 2.
Further, the area sum of the xsect of described complex root fiber accounts for 50%～98% of described cylindrical cross-sectional area.
Further, described right cylinder has hardness.
Further, described right cylinder has radially tear strength.
Further, described right cylinder has toughness, and described toughness is resisted axial 180 ° bending at least.
Further, described cylindrical surface is near of the same colour, or is printed on numeral or literal or pattern.
Further, described cylindrical any surface finish, perhaps coated has one deck powder.
Further, the particle of described powder is more than 200 orders.
Further, described powder is water-proofing powder or talcum powder or lime carbonate.
Further, described powder is two or more the potpourri in water-proofing powder, talcum powder and the lime carbonate.
Principle of work of the present utility model is: in optical cable processing, a kind of optical cable of the present utility model is placed on by optical fiber or the fibre ribbon with the FFRP bar is parallel, or is placed in the cable core, or be stranded in outside beam tube or the cable core, squeeze jacket plays in optical cable and strengthens and the lateral pressure resistant effect again.
The utility model and prior art compare, and its effect is actively with tangible.Because of wherein there not being ferrous materials such as steel wire, there is not the problem of iron oxidation liberation of hydrogen in the optical cable that utilizes the utility model to produce; Use at multi-thunder area, avoided thunderstruck possibility; Just because of this, the optical cable that utilizes the utility model to produce can indoor and outdoor all can use.And the tubular FRP (glass fiber reinforced plastics) of rigidity can fracture when bending radius is too small, and optical cable need be converted into 90 ° when indoor laying.The utility model can not rupture when being converted into 180 ° yet.So the utility model is the preferred reinforcement of indoor and outdoor general optical cable, particularly inside cable, especially butterfly optical cable.In the optical cable process, the utility model plays booster action in optical cable.Replace steel wire, do not have iron oxidation liberation of hydrogen; When using, multi-thunder area can exempt from thunderbolt; Overcome the deadly defect that common FRP rod bending radius hour fractures again.
