Jet flame and hydrocarbon flame resistant medium-voltage cable for offshore oil platform and manufacturing method thereof

The invention relates to a jet flame and hydrocarbon flame resistant medium-voltage cable for an offshore oil platform and a manufacturing method thereof. A semi-conductive conductor shielding layer,an insulating layer and a semi-conductive insulating shielding layer wrap the periphery of a stranded tin-plated annealed copper conductor from inside to outside in a three-layer co-extrusion mode; atinned copper wire shielding layer is woven on the periphery of a semi-conductive insulation shielding layer to form a shielding wire core, a plurality of shielding wire cores are twisted to form a cable core, an inner silicone oil layer is extruded on the periphery of the cable core, an inner lining layer is extruded on the periphery of the inner silicone oil layer, a fireproof wrapping tape is wrapped on the periphery of the inner lining layer, and an armor layer is wrapped on the periphery of the fireproof wrapping tape; the periphery of the armor layer is extruded with an outer silicone oil layer, the periphery of the outer silicone oil layer is extruded with a jet flame and hydrocarbon flame resistant inner sheath, and the periphery of the jet flame and hydrocarbon flame resistant inner sheath is extruded with a slurry resistant cross-linked polyolefin outer sheath. The cable adopts a double-layer composite sheath, can bear high-temperature flame of 1300 DEG C for 120 minutes under rated voltage, and does not have a grounding fault or a short circuit.

Non-migrating hydrophilic anti-fogging master batch for polyolefin film and preparation thereof

The invention relates to a non-migrating hydrophilic anti-fogging master batch for polyolefin film and a preparation thereof. The preparation mainly comprises: (1) SiO2 surface hydroxylation treatment; (2) using surface hydroxylated treated SiO2 as the reaction core, allowing carboxyl-containing and hydroxyl-containing functional monomer DMPA and the surface hydroxyl groups of SiO2 to perform condensation polymerization reaction to obtain hyperbranched polyester grafted modified SiO2; (3) use one of 6C to 18C hydroxyl-containing alkyl acyl chloride, 6C to 18C saturated long-chain alkanoic acidor epsilon-caprolactone to modify the hyperbranched polyester grafted modified SiO2obtained in step (2). The invention utilizes the hyperbranched polyester grafted modified SiO2, silica anti-stickingparticles are uniformly distributed on the surface of the film, the roughness of the film surface is improved to a certain extent, and the hydrophilic group can further reduce the contact angle of water mist, thereby synergistically playing a better anti-fogging effect, so that the non-migrating anti-fogging master batch of the invention has anti-sticking performance and anti-fogging performanceat the same time. The non-migrating hydrophilic anti-fogging master batch is especially suitable for the film which can not be corona treated but needs excellent anti-fogging effect.
