The outer coating layer is coated on the surface of the aromatic polyamide fiber due to the adoption of the optical-curable process, and the prescription of the optical-curable adhesive is adjusted, so that the physical property of the outer coating is combined with that of the aromatic polyamide fiber to satisfy the requirement of the optical cable reinforcing core; and in addition, the energy consumption is lowered and the production period is shortened.
Description
Technical field
The present invention relates to a kind of aramid fiber strengthening core and production method thereof that is used to increase optical cable intensity.
Background technology
For increasing the intensity of optical cable, optical cable inside is provided with optical cable strengthening core.Adopting more optical cable strengthening core at present is steel wire, glass fibre and aramid fiber, use the reinforced-core of steel wire as optical cable, can increase the intensity of optical cable, but since the poor corrosion resistance of steel wire generally use and will get rusty in 2 years, produce harmful gas, cause hydrogen loss, influence the propagation performance of optical fiber, the serviceable life of this steel wire strengthening core is not long; Though traditional glass fiber reinforced plastics optical cable strengthening core has high-strength light, corrosion-resistant, antistatic and anti-advantage such as nibble, but throughput rate is slow, bending radius is bigger, and in a single day takes place to rupture just can't re-use, and poor with the associativity of the desired PE protective cover material of industry; Aromatic polyamide optical cable reinforcing core is to be matrix material with the aramid fiber, resin is binding material-kind of novel optical cable strengthening core, its basic skills principle is consistent with the glass fiber cable strengthening core, aramid fiber has better mechanical property and physicochemical property than glass fibre simultaneously, can overcome big, the heavier shortcoming of quality of glass fiber cable strengthening core bending radius largely, and have higher pulling strengrth and anti-fracture characteristics, be the good substitute products of glass fiber cable strengthening core.
Traditional aramid fiber strengthening core with thermoset resin as binding material, for example: epoxy resin, vinylite or ethylene acrylic acid co polymer or the like, in the heat curing production run, the temperature in slaking zone needs will be controlled at about 200 ℃, with the cured thermoset resin, therefore consumes energy is more, and production efficiency is low, and, thermoset resin needs time a few minutes at least because making its generation chemistry reach solid state by heating, therefore prolong the production cycle of entire product, reduced production efficiency; Needed in addition production equipment is complicated, needs very long heat curing cavity, and its effective working cavity is not less than 600mm.
Ultraviolet light (UV) curing technology is an energy-conservation and environment-friendly novel technology, and it has the energy, ecological environmental protection and the economy of saving, and therefore the production efficiency advantages of higher demonstrates great vitality in production application.Obtain first UV curable ink patent from nineteen forty-six American I nmont company, nineteen sixty-eight, Germany Bayer company developed first generation ultraviolet cured woodware coating, UV-curing technology has obtained to develop rapidly in the world, be widely used in chemical production field at present, but, do not see at present the report that UV-curing technology is applied to the preparation field of aromatic polyamide optical cable reinforcing core, because prepare aromatic polyamide optical cable reinforcing core, need consider the physical property that is coated in the outer coating of aramid fiber, comprise performances such as physical strength and pliability.
