Specific embodiment
Strengthen core present embodiment discloses a kind of selfreparing optical cable containing microcapsules, its preparation is by self-repairing microcapsule Prepared by quiet pultrude process with after unsaturated polyester (UP) blending.Selfreparing enhancing core containing microcapsules, by following weight portion Composition is constituted:
5~15 parts of selfreparing capsule;
2~4 parts of catalyst;
81~93 parts of liquid resin matrix.
Wherein nanometer-sized microcapsules particle its have preferable repairing effect.The cyst wall of self-repairing microcapsule is:Urea and 37% formalin is with the ratio between amount of material for 0.5~0.6:Lauxite prepared by 1 ratio, capsule-core is two polycyclopentadithio.henes Alkene.
The present embodiment also discloses a kind of selfreparing optical cable enhancing core containing microcapsules and preparation method thereof, including following Step:
(1) preparation of self-repairing microcapsule:Urea is dissolved in 2.5% EMA acid anhydride (EMA) in the case where environment is stirred molten In liquid, after after urea all dissolving, appropriate ammonium chloride and resorcinol are added.Reaction system pH is adjusted with hydrochloric acid and NaOH =4~5, dicyclopentadiene is added, after stabilization forms emulsion, it is eventually adding 37% formalin, (urea and 37% Formalin is with the ratio between amount of material for 0.5~0.6:1).System heating is to 55 DEG C of reaction 4h.Room temperature is cooled to, suction filtration is washed Wash, natural air drying sieve sieve takes standby.
(2) preparation of blend:
5~15 parts of micro-crack selfreparing capsule;
2~4 parts of catalyst;
81~93 parts of liquid resin matrix.
After blends described above is prepared in proportion, it is sufficiently stirred for 30-60 minutes, makes microcapsules and catalyst mixed distribution Uniformly.
(3) pultrude process:Blend containing microcapsules will be prepared to be prepared for pultrusion, passed through with the speed of 0.01m/s 160 DEG C~180 DEG C of mould and 280 DEG C of hot setting.Self-reparability is prepared after microcapsules and mixed with resin to exhale and nothing, wherein The mass content of microcapsules is 5wt%~15wt%.
Further, control 300~600r/min of mixing speed in step (1), with obtain particle size range 180nm~ The nanometer-sized microcapsules of 300nm.
Further, in step (1), reaction system carries out reaction preparation under being in air-proof condition.
In the above-mentioned technical solutions, the selfreparing mixture resin is unsaturated polyester resin.Wherein unsaturated polyester (UP) Huge number washability is also greatly increased.
In the above-mentioned technical solutions, it is micro- when coating occurs crackle during reparation, it is necessary to additionally add catalyst Capsules break, dicyclopentadiene can be rapidly permeated into, and run into Grubbs catalyst actions and produced polymerization crosslinking, to reach reparation Purpose.The expansion of the failure mode such as coating damage, stripping caused by after inhibiting coating to crack.
The repair mechanisms of this case are that crackle produces the selfreparing of induction microcapsules to occur, and reduce the cumbersome work of manual detection Make.Have in coating crack initiation and growth, coating by external force crimp, have micro-crack can promote repair microcapsules cyst wall break Split, the renovation agent in intelligent corrosion-inhibiting coating can fill crackle from intracapsular outflow.
Under general conditions under environment, this case selfreparing optical cable enhancing core stable storing can be used for various compound Activeness and quietness material.
