Abstract

The invention discloses a formula and a production method of a halogen-free antimony-free flame-retardant high-temperature-resistant heat-shrink pipe material. The formula comprises the following components in parts by weight: 10 to 50 parts of polyethylene, 30 to 60 parts of ethylene-methacrylate copolymer, 10 to 35 parts of ethylene-vinyl acetate copolymer, 30 to 80 parts of lithium aluminium silicate, 10 to 30 parts of microencapsulated red phosphorus, 35 to 90 parts of halogen-free composite flame retardant, 0.5 to 2 parts of lubricating agent, 2 to 4 parts of silicone, 0.5 to 1.5 parts ofsensitized crosslinking agent and 3.5 to 6.5 parts of composite antioxidant. The halogen-free antimony-free flame-retardant high-temperature-resistant heat-shrink pipe material has excellent environmental friendliness which can accord with Japan SONY-SS-00259 standard, European Union REACH laws and regulations and RoHS 2.0(2011 / 65 / EU) instruction, and does not contain any halogen such as bromineand chlorine and antimony flame retardants.

Description

technical field [0001] The invention relates to the technical field of heat-shrinkable tube materials, in particular to a halogen-free, antimony-free, flame-retardant, high-temperature-resistant heat-shrinkable tube and a production method thereof. Background technique [0002] Heat shrinkable sleeves are generally used in the connection between various wires and cables, as well as the connection of cable terminals, to identify or protect wires and cables. With the rapid development of the automobile industry, domestic aircraft development projects, high-speed rail transit industry, and the needs of military equipment development, some spare parts and wires and cables required for these equipment need to be used at higher temperatures for a long time, which requires cooperation with The matching heat-shrinkable tubing has good flame retardancy and high temperature resistance; while most of the high-temperature resistant heat-shrinkable tubing currently used is a halogen-cont...
