Abstract

The invention discloses a soft and flexible heat-shrinkable with properties of high fire retardance and oil resistance. The heat-shrinkable tube comprises the following preparation materials in parts by weight: 10-60 parts of modified thermoplastic polyester elastomers, 0-60 parts of polyethylene, 40-100 parts of oil resistant rubber, 25-100 parts of fire retardant, 0.2-8 parts of lubricant, 0.1-2 parts of sensitized crosslinking agent, 0.5-3 parts of antioxidant, 0-8 parts of carbon black, and 0-10 parts of color master. The soft and flexible heat-shrinkable with properties of high fire retardance and oil resistance disclosed by the invention has a good fire retardance effect which can achieve American UL224VW-1 and comply with ROHS environment-friendly requirements at the same time, and has a good oil resistance effect which can achieve the standard requirements of American military standard SAE-AMS-DTL-23053 / 16.

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 ...
