Description
Technical field
The present invention relates to a kind of improvement of optical cable strengthening core, refer in particular to and a kind ofly have good physical and mechanical properties, pliability, high temperature resistant, simple and convenient during stranding, the properties of optical fiber cable made can reach and be better than the elastic composite fiber reinforcing core of national standard equally.
Background technology
At present, the matrix material that inside cable strengthening core adopts is mainly glass fibre, aramid fiber and high-strength high-modulus polyethylene fiber.Glass fibre strengthening core (GFRP), owing to adopting epoxy resin thermosetting cladding process, causes the rigidity of GFRP own to be had a surplus and flexible not enough, its optical cable made and easily breakage phenomenon occurs.Aramid fiber reinforcing core (KFRP) due to material price own higher, cause use face not to be very wide.High-strength high-modulus polyethylene fiber obtains certain application as newfound optical cable strengthening core matrix material recent years, but because the non-refractory of polyethylene fibre own and material behavior make so, stranding is added and man-hour and difficulty and the optical cable made thereof there is certain abnormality, for this reason, we have developed a kind ofly has good physical and mechanical properties, pliability, high temperature resistant, simple and convenient during stranding, the properties of optical fiber cable made can reach and be better than the elastic composite fiber reinforcing core of national standard equally.
Summary of the invention
The present invention seeks to provide a kind of have good physical and mechanical properties, pliability to overcome the deficiencies in the prior art, high temperature resistant, simple and convenient during stranding, the properties of optical fiber cable made can reach and be better than the elastic composite fiber reinforcing core of national standard equally.
For achieving the above object, the technical solution used in the present invention is: elastic composite fiber reinforcing core, comprises matrix fiber, cured layer, clad; Described cured layer is wrapped on the outside surface of matrix fiber; Described clad is wrapped on the outside surface of cured layer; Described matrix fiber is mixed by high-strength and high-modulus glass fibre and polyethylene fibre, and described high-strength and high-modulus glass fibre accounts for mass percent 40-60%.
Preferably, described cured layer is made up of optic-solidified adhesive; Described optic-solidified adhesive, comprises, by mass percentage: polyurethane vinyl acid esters accounts for 70-80%, hardening agent accounts for 10-20%, initiating agent accounts for 2-5%, levelling agent account for 2-4% all the other for water.
Preferably, the thickness of described cured layer is 0.05-0.06mm.
Preferably, described clad is made up of nylon.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Elastic composite fiber reinforcing core of the present invention has good physical and mechanical properties and splendid pliability, simultaneously can be high temperature resistant, reduces technical requirement during stranding.The optical cable made not only has good performance, and can bear repeatedly bending and folding and ensure that optical fiber is wherein injury-free.
