Abstract

The invention discloses a thermoplastic low-smoke halogen-free flame-retardant polyolefin special material for oil filled bushing and a preparation method thereof, and belongs to the technical field of low-smoke halogen-free flame-retardant polyolefin plastic. The special material comprises following components in parts by weight: 15 to 25 parts of polypropylene, 10 to 25 parts of high density polyethylene, 15 to 40 parts of thermoplastic vulcanized rubber, 10 to 25 parts of ultralow density polyethylene, 5 to 15 parts of a compatibilizer, 1 to 5 parts of high molecular weight polysiloxane, 0.1 to 0.5 part of a nucleating agent, 120 to 180 parts of a composite fire retardant, 0.5 to 2.5 parts of a tubular microcrystal nano charring agent, 0.5 to 2 parts of organic silane, 0.5 to 2 parts ofan antioxidant, and 1 to 3 parts of a processing aid. The provided thermoplastic low-smoke halogen-free flame-retardant polyolefin special material has the advantages of fireproof and flame retardantproperties, easiness for processing, oil-proof and high temperature resistant properties, swelling resistant performance, and good mechanical properties, and is suitable for oil filled bushing and oil-proof cable sheaths. Moreover, the invention also provides a preparation method of the special material, and the preparation method has the advantages of simple and continuous process, high production efficiency, and stable product quality.

Description

technical field [0001] The invention belongs to the technical field of low-smoke, halogen-free, and flame-retardant polyolefin plastics, and in particular relates to a thermoplastic low-smoke, halogen-free, and flame-retardant polyolefin special material for oil-filled casings and a preparation method thereof. Background technique [0002] With the start of 5G network construction, artificial intelligence, big data, cloud computing, and smart cities will further accelerate the construction, and the demand for new optical cables and optical fibers will rise sharply, especially for backbone networks, metropolitan area networks, and access networks. The consumption of optical cables has increased sharply, including optical cables and wires used in mixed scenarios such as smart transportation, industrial platforms, and computing centers, all of which have high requirements for water resistance, oil resistance, and solvent resistance. The main scheme has good comprehensive perfor...
