Problems solved by technology

However, polyester elastomers have disadvantages such as poor insulation performance, easy hydrolysis, and poor aging performance, and cannot be used for a long time at 150°C; while fluorine-containing materials can meet the temperature resistance requirements, but halogen-containing materials are not halogen-free materials; irradiation crosslinking Polyolefin materials require irradiation processing, which has high processing costs, low strength, and poor wear resistance; silicone rubber has complex processing technology, low strength, poor wear resistance, and worse insulation performance; polyimide and polyetheretherketone (PEEK) are more is difficult to process and expensive

Abstract

Provided are a 150 DEG C thermoplastic halogen-free flame-retardant polyolefin thin-wall insulation material and a preparation method thereof. The insulation material comprises the main components in parts by weight: 60 to 70 parts of poly(4-methyl-pentene) resin, 10 to 20 parts of thermoplastic hydrogenated styrene butadiene rubber, 10 to 20 parts of a compatilizer, 50 to 60 parts of a flame retardant, 0.5 part of an antioxidant A, 0.3 part of an antioxidant B, 0.3 part of an anti-copper agent, and 2 parts of a lubricant. The preparation method comprises the steps: after preparing the amounts of the raw materials according to the weight parts, putting into a mixer for mixing evenly, then sending into a twin-screw extruder for co-mixing, filtering, extruding and dragging strips, next cooling with a water tank, drying, allowing to go into a dicing cutter for cutting into particles, and then packaging to obtain the finished product. The insulation material has the advantages of good insulating performance, excellent flame retardance, high temperature resistance, easy processing and low cost, and can be widely used in thin-wall insulation of communication cables, locomotive vehicle wire cables and automobile wires; and the preparation method is reasonable in design and simple in operation.
