Embodiment
[0029] See Table 1 for the specific ingredients of the rubber sheath materials in Examples 1 to 3 by weight.
[0030] Wherein, the concrete preparation steps of detection sample in embodiment 1~embodiment 3 are as follows:
[0031] 1) Cut ethylene acrylate rubber into pieces and add to the internal mixer, then sequentially add lubricant, processing aid, anti-aging agent, flame retardant and plasticizer, and mix to obtain the mixed rubber;
[0032] 2) After the mixed rubber material in step 1) is uniformly removed, the film is obtained, and the film is parked for use;
[0033] 3) Put the film in step 2) into the internal mixer, then add a vulcanizing agent, and after vulcanization, the vulcanized rubber material is uniformly removed again, and the obtained film is naturally cooled to prepare a test sample.

Abstract
The invention discloses a halogen-free, low-smoke and flame-retardant rubber sheath material resistant to low temperature of -50 DEG C and ASTM3# oil. The halogen-free, low-smoke and flame-retardant rubber sheath material is prepared from, by weight, 60-80 parts of hydrogenated nitrile rubber, 190-220 parts of flame retardant, 1 part of lubricant, 3 parts of vulcanizing agent, 1 part of anti-aging agent, 5 parts of plasticizer and 1 part of processing aid, wherein the flame retardant is prepared from a flame retardant master batch, zinc borate and silane treated magnesium hydroxide. The low temperature resisting performance of the rubber sheath material can be up to -50 DEG C and can be resistant to ASTM3# oil. In addition, the flame retardancy of the rubber sheath material is excellent, the oxygen index can be about 34, and the material is suitable for high-performance production requirements.
Description
technical field [0001] The invention discloses the technical field of flame-retardant cables, in particular to a halogen-free low-smoke flame-retardant rubber sheath material resistant to low temperatures of -50°C and ASTM3# oil. Background technique [0002] In recent years, with the country's emphasis on environmental protection and safety, some large buildings or public places, such as large shopping malls, entertainment venues, subways, stations, ships, nuclear power plants, etc., require the use of low-smoke halogen-free flame-retardant cables. [0003] At present, low-smoke halogen-free flame-retardant cable materials have achieved rapid growth in product output, but they also need to follow up in performance and types. Depending on the environment in which the cables are used, the performance requirements of the cables are also different. For example, locomotive cables and marine cables require not only low-smoke, halogen-free flame retardant, but also oil resistance ...
