Description

A kind of fiber reinforced plastics pole and production method thereof and application
Technical field
The invention belongs to optical cable field, particularly to a kind of fiber reinforced plastics pole and production method thereof and application.
Background technology
Increasing with information transfer demands for communication recently as the mankind, communications industry is fast-developing, and vigorous is logical Letter consumption demand is that optical fiber cable industry development provides the wide market space, and consumption increases year by year.
The basic structure of optical cable is usually by several parts such as cable core (optical fiber), strengthening core (guard member), implant and sheaths Composition, according further to components such as needs also waterproof layer, cushion, insulated metal wires.Wherein the effect of strengthening core carries exactly The integrally stretching intensity of high optical cable, it is ensured that optical cable construction and use in due to cable body in reinforcement high-tension performance and not Easily it is pulled off, thus protects the not easy fracture of the optical fiber in optical cable.Common strengthening core has steel wire, silvalin, fiber reinforcement plastic Material bars etc., the enhancing fiber of use has glass fibre, aramid fiber, superhigh molecular weight polyethylene fibers etc..
In prior art, the production method of fiber reinforced plastics pole mainly has two kinds.
One is heat reactive resin pultrusion method.Chinese patent CN100449347 discloses a kind of aramid fiber and increases The preparation method of strong plastic reinforcement, uses aramid fiber, dipping vinylite, through the heat cure molding of 5～8m/min, outward Cover EVA coating.Chinese patent CN102692686 discloses the production method of a kind of optical cable fiber reinforced plastics pole, uses glass Glass fiber, aramid fiber, basalt fibre, steel wire or carbon fiber, impregnate heat-curable urethane or the carbamide resin of certain formula proportion, Through the heat cure molding of 100～250 DEG C, speed of production is the highest can be to 10m/min.Chinese patent CN102896783 discloses one Plant the production method of optical cable fiberglass-reinforced plastic lever, use glass fiber yarn to impregnate with polyether polyol, asphalt mixtures modified by epoxy resin Fat is the thermosetting resin of matrix, is wound into drum after the continuous multiple tracks heat cure of 80～220 DEG C, and speed of production can be to 4 ～8m/min.The shortcoming of this production method is that throughput rate is limited to heat cure, generally below 10m/min.For optical cable row The plastic bar of normally used 50km/ volume of industry, the single-deck production cycle is up to 3.5 days～8 days, and production efficiency is extremely low and quality one Cause is difficult to ensure that.
One is that polymer melt coating allows formed by extrusion and tension.Chinese patent CN102608718 discloses a kind of thermoplasticity The production technology of GFRP butterfly optical cable reinforcement, uses glass fibre carry out the heat coating of twice polymer melt and cool down Solidification, polymer used is polyethylene, polypropylene, polyester, polyamide or polyformaldehyde etc..The shortcoming of this production method lies also in life Producing speed, the high viscosity of polymer melt strongly limit coating efficiency, and will be difficult to penetrate into fibrous inside, obtained Plastic bar performance the most inconsistent.
It addition, PCT Patent WO2012/091806 discloses the new method for producing of a kind of cable strengthening core, use one Aqueous polymer dispersion moistening fiber, the rear moisture that removes makes polymer be fixedly arranged at fiber surface thus prepared reinforcement.
