Abstract

The invention relates to a water-blocking paste for a semi-dry optical cable, comprising the following raw materials in parts by mass: 50-70 parts of polyolefin oil, 17-20 parts of synthetic aromatic oil, 12-18 parts of polymer oil inhibitor, and 30 parts of paraffin oil ~50 parts, 3~5 parts of fumed silica, 1~3 parts of antioxidant, 7~10 parts of silicone rubber, 6~12 parts of acrylic superabsorbent resin, 0.3~0.6 parts of organic amine. The water-blocking paste for a semi-dry optical cable provided by the invention has stable physical and chemical properties, uniform material distribution, is not easy to flow, resists aging, and has a long service life.

Description

technical field [0001] The invention belongs to the technical field of water-blocking materials, and in particular relates to a water-blocking paste for semi-dry optical cables. Background technique [0002] With the rapid development of communication technology, the application fields of optical cables are expanding day by day, the environmental requirements are also increasing, and the quality requirements and scope of application of optical cable materials are also increasing. In order to ensure the longitudinal sealing of the optical cable and prevent the intrusion of water and moisture into the interior of the optical cable and affect the communication quality of the optical cable, the current water blocking tape is usually used for optical cable. The material of the water blocking tape is mostly powdery and granular, which is prone to displacement during the handling and use of the optical cable, resulting in uneven expansion of the material, thus affecting the actual ...
