High-water-absorption swelling waterproof cream for optical cable
The invention relates to materials for cables and particularly relates to high-water-absorption swelling waterproof cream for an optical cable. The high-water-absorption swelling waterproof cream is prepared from the following raw materials in parts by weight: 50-70 parts of poly-alpha-olefin synthetic oil, 30-50 parts of paraffin oil, 7-10 parts of silicon rubber, 5-8 parts of silica powder, 3-5 parts of fluorocarbon acrylate resin, 6-12 parts of super-absorbent resin, 0.3-0.6 part of N-phenyl-alpha-aniline and 0.2-0.4 part of melamine cyanurate. The high-water-absorption swelling waterproof cream for the optical cable, provided by the invention, is uniform in material distribution and difficult in flow and is prepared from composite materials, so that the waterproof cream is ageing-resistant and has a long service life. 1. Optical cable by using a high water-absorbing swelling anti- Shui Gao , characterized in that the following raw materials in accordance with the weight of the preparation, poly α-olefin synthetic oil 50-70 parts, paraffin oil 30-50 parts, silicon rubber 7-10 parts, silicon dioxide powder 5-8 parts, acrylic acid resin fluorine hydrocarbon ester 3-5 parts, high water-absorbing resin 6-12 parts, N-phenyl-α-aniline 0.3-0.6 parts, melamine cyanurate 0.2-0.4 parts. 2. Optical cable by using a high water-absorbing swelling anti- Shui Gao according to Claim 1, characterized in that the preparation process is: The poly-α olefin synthesis uniformly mixing the oil and paraffin oil, boiling and distillation after heating under negative pressure, to remove volatile matter and water To the other raw materials, mixing until the paste; After grinding, uniform stirring after grinding; The filter packing.
