Abstract

The invention discloses a semi-hard high-flame-retardant oil-proof thermal shrinkage tube. The material for preparing the thermal shrinkage tube comprises the following components in parts by weight: 100 parts of polyethylene and ethylene vinyl acetate copolymer, 0 to 30 parts of ethylene terpolymer, 30 to 150 parts of a fire retardant, 0.2 to 3 parts of a lubricant, 0.1 to 3 parts of a sensitized crosslinking agent, 0.3 to 3 parts of an antioxidant and 0 to 10 parts of a color master batch. The semi-hard high-flame-retardant oil-proof thermal shrinkage tube has a good flame-retardant effect, meets an ROHS environmental protection requirement, has a better oil-proof effect and can meet a standard requirement of an American military standard (SAE-AMS-DTL-23053 / 6), and the flame retardant rating of the thermal shrinkage tube can reach an American UL224 VW-1 standard.

Description

technical field [0001] The invention relates to a highly flame-retardant and oil-resistant heat-shrinkable tube and a production method thereof. Background technique [0002] Heat shrinkable sleeves are generally used in the installation of wires and cables to insulate, protect or mark wires and cables. With the development of the automobile industry and domestic aircraft development projects, high-speed rail transit and military equipment development needs. Some of the wires and cables required for these equipment will be more or less exposed to some fuel oil during use, which requires that the wires and cables have better flame retardancy and fuel oil resistance, and at the same time need to match the heat The shrink sleeve also has good flame retardancy and fuel oil resistance. [0003] However, due to the problem of material selection, the heat-shrinkable sleeves currently used generally only have flame-retardant properties, but not oil-resistant properties. Abrasive ...
