Description
Technical field
The present invention relates to a kind of cable-filling material, relate in particular to a kind of cold applied optical cable water-blocking factice for filling.
Background technology
Because people cannot strictly control its envrionment conditions, the optical cable of outdoor laying is conventionally under a kind of changeable envrionment conditions, because the variation of environment temperature and humidity can cause producing pressure difference inside and outside cable jacket, and then cause that non-directional diffusion occurs from optical cable outside to inside ambient moisture, cause optical cable inside in high humidity state, the high humidity of optical cable inside may cause the loss of transmission signal.
In addition, in optical cable laying process, mechanical impact may cause sheath breakage, in long-term use procedure, illumination, electric shock, water soaking etc. also can cause sheath season cracking, also can cause moisture, moisture etc. to enter optical cable inside from the damaged cracking of sheath, equally also cause the loss of transmission signal.
Thus, we need to additionally increase a kind of protective layer between optical cable core and sheath, to prevent that moisture or moisture from entering optical cable inside.Early stage optical cable uses hydrophobicity thixotroping ointment to be filled between cable core and sheath moisture is isolated conventionally, and this ointment only hydrophobicity of utilization itself deadens moisture, and block-water effect is poor.A small amount of process using Vaseline base oil cream or rubber-type ointment carry out high warm filling protection cable core; which is filled full, even; but complex process; and high temperature production and the meeting of filling produce certain pollution; the peculiar smell producing under high temperature can cause human body to produce sense of discomfort, even affects direct labor's health.
Optical cable factory all starts to adopt expansion greasy for preventing water to fill in a large number at present; after the ointment of this type is filled in optical cable; can absorb the moisture, the moisture that enter optical cable inside due to a variety of causes; absorbing after steam; ointment expands; further infiltration and the diffusion of the moisture just intercepting, thus reach the protection effect good to optical cable.
At present commercially available greasy for preventing water on cable all has formula complicated, and cost is high, and the shortcoming of unstable properties, is difficult to meet market for ointment production process simply and requirement cheaply.
Summary of the invention
The object of this invention is to provide a kind of formula simple, production technique is simple to operation, the greasy for preventing water on cable that cost is low.The features such as it is fast that this ointment has absorption speed, and water absorbent rate is high, and point oil mass is little, and cone penetration is large, and thixotropic property is good, and dropping point is high, and antioxidant property is good.
For achieving the above object, the technical solution used in the present invention is: the cold applied expansion factice for filling that blocks water, its moiety is: base oil 65%～80%, oil absorbing polymer resin 3%～8%, hydroscopic high-molecular resin 5%～10%, tackifier 2%～4%, thickening material 10%～18%, oxidation inhibitor 0.3%～0.8%, dispersion agent 1%～2%, softening agent 1%～2%.
More specifically technical scheme is: in base oil, add oil absorbing polymer resin and tackifier, under stirring, be heated to 130～160 DEG C and make it to be melt into homogeneous, then add oxidation inhibitor, dispersion agent and softening agent, continue insulated and stirred 30～60min, be cooled to below 80 DEG C, add thickening material and hydroscopic high-molecular resin, continue to stir 30～60min, degassed, discharging.
Described in technical scheme, base oil can be selected hydrogenation white oil, lubricant base or the synthetic alkene oil of appropriate viscosity; Oil absorbing polymer resin is selected styrene butadiene block polymer hydrogenation products; Hydroscopic high-molecular resin is selected polyacrylic resin or the polyacrylamide of part neutralization; Tackifier are selected ethylene propylene rubber or terpolymer EP rubber; Thickening material is selected thermal silica, wilkinite or diatomite; Oxidation inhibitor is commercially available phenol oxidation inhibitor or phenyl amines oxidation inhibitor, and dispersion agent and softening agent are also commercially available prod.
The factice for filling that blocks water of the present invention is according to being " the communications industry standard YD839-2000 of the People's Republic of China (PRC) ", and all technical indicators all meet this standard-required.
