Problems solved by technology

[0002] In recent years, with the continuous development and application of communication electrical (optical) cables, their long-term reliability has been paid more and more attention. During the long-term use of electrical (optical) cables, due to the erosion of moisture and moisture, It leads to the decline of transmission performance and affects normal use. People's research in this area has gone through the first generation of inflation maintenance to the second generation of hot filling grease, and finally to the use of the third generation of cold filling grease. It is an important link in the production of electric (optical) cables, and its performance index directly affects the quality of the cable. For example, the oil separation of the filling paste is to assess the amount of oil separated from the filling paste at a certain temperature. If the oil separation is too large, The oil is easy to drip from the cable core during use; since the filling paste contain

Example Embodiment

[0023] Example one

[0024] Pour the base oil composed of 60g hydrogenated white oil and 10g lubricating oil into the kettle and heat it to 70℃, then add 0.6g phenol antioxidant and 4.5g alkylphenol polyoxyethylene ether emulsifier into it in sequence , And 7.8g water blocking agent, fully stir for 5 hours, after the entire liquid is completely emulsified, quickly cool it to room temperature through a cooling device, and then add 6g white carbon black and 2g diatomaceous earth to the cooled mixture. Thickener, and 0.6g fatty acid ester dispersant, stir uniformly for 0.5 hours, and finally add 8.5g of cross-linked sodium polyacrylate polymer water-absorbing resin to the uniformly stirred mixture. After uniformly stirring, the mixture is mixed with a vacuum pump The air bubbles are drawn out, and the mixture is poured out of the container after the air extraction is completed.

Example Embodiment

[0025] Example two

[0026] Pour 75g of synthetic olefin oil base oil into the kettle and heat it to a temperature of 80°C, then add 0.2g of phenolic antioxidants and 0.3g of aniline antioxidants to it, and 3.5g of benzene. Ethyl phenol polyoxyethylene ether emulsifier and 8g water blocking agent, fully stirred for 5.5 hours, after the entire liquid is completely emulsified, quickly cool it to room temperature through a cooling device, and then add 5g bentonite to the cooled mixture to thicken it And 0.5g of paraffin wax dispersant. Stir uniformly for 0.8 hours. Finally, add 7.5g of polyacrylonitrile-based polymer water-absorbing resin to the uniformly stirred mixture. After uniformly stirring, the bubbles in the mixture are removed by a vacuum pump. Take it out, and pour the mixed liquid out of the container after the gas is pumped.

Example Embodiment

[0027] Example three

[0028] Pour the base oil of 80g hydrogenated white oil into the kettle and heat it to a temperature of 90°C, then add 0.2g phosphite triester antioxidant, 2g fatty alcohol polyoxyethylene ether emulsifier, and 8.5g hinder Water agent, fully stir for 6 hours, after the entire liquid is completely emulsified, quickly cool it to room temperature with a cooling device, and then add 3g diatomite thickener and 0.3g paraffin dispersant to the cooled mixture for uniformity Stir for 1 hour, and finally add 6g of polymer water-absorbing resin synthesized by polyacrylonitrile resin to the evenly stirred mixture. After uniformly stirring, the bubbles in the mixture are extracted by a vacuum pump, and the mixture is poured after the exhaustion is completed. Out of the container.

Abstract

The invention discloses a cold application water-blocking type optical power cable filling past. The filling past comprises the following components in weight percentage: 70% to 80% of base oil; 2% to 5% of emulsifier; 5% to 10% of super absorbent polymer; 3% to 10% of thickener; 0.2% to 1% of antioxidant; and 0.2% to 0.8% of dispersant. The invention further provides a production method of the filling paste. The production method includes the following steps that: base oil is heated to 60 DEG C to 100 DEG C, a proper amount of an antioxidant, an emulsifier and a water resistance agent are added to the base oil, and an obtained liquid is fully stirred for 5 hours to 6 hours, and the liquid is completely emulsified, the liquid is fast cooled to room temperature through cooling equipment; a thickener and a dispersant are added into the liquid, and an obtained mixture is stirred uniformly for 0.5 hours to 1 hours; and polymer water-absorbent resin is added into the mixture, and a newly obtained mixture is stirred uniformly, air bubbles in the mixture are extracted through a vacuum pump, after air pumping, emptying is carried out. The filling paste produced by the production method of the invention has the advantages of good water resistance and lower production cost.
