Abstract

The invention discloses a high-temperature resistant halogen-free flame-retardant cable material and a preparation method thereof. The cable material comprises the following components by weight percent: 60% to 80% of thermoplastic polyether ester elastomer, 10% to 20% of triphenyl phosphate intercalated montmorillonite, 6% to 15% of novolac epoxy resin, 3% to 15% of nitrogen-containing flame-retardant synergist, 0.1% to 0.5% of antioxidant A and 0.1% to 0.5% of antioxidant B, wherein the antioxidant A is selected from double (2,4-two tertiary butyl phenyl) pentaerythritol phosphate, 4-{3-(3,5-two tertiary butyl-4-hydroxyl phenyl) propionic acid} ntaerythritol alcohol ester or Beta (3,5-two tertiary butyl-4 hydroxyl phenyl) octadecyl propionate; and the antioxidant B is selected from (2,4,6-three tertiary butyl phenyl-2-butyl-2-ethyl)-1,3-propylene glycol phosphite ester, 2,2'-ethylidene double (4,6-two tertiary butyl phenyl) fluoro phosphite ester or 2(2,4-2 pair isopropyl phenyl) pentaerythritol double phosphite ester. The cable material disclosed by the invention is good in mechanical and processing performance, strong in stress cracking resistance and high in high-temperature resisting level.

Description

technical field [0001] The invention belongs to the field of cable materials, and in particular relates to a high-temperature-resistant halogen-free flame-retardant cable material and a preparation method of the cable material. Background technique [0002] Thermoplastic polyether ester elastomers are widely used in the field of cables due to their comprehensive properties such as outstanding mechanical strength, excellent resilience and wide service temperature, but their shortcomings such as flammability and droplet seriously affect its Application and promotion. In addition, the long-term working temperature of the current thermoplastic polyether ester elastomers is mostly 125 degrees, which still does not meet the requirements for high temperature resistance of 150 degrees (for example, according to the ISO6722-2006 international automotive wire standard, the long-term working temperature of automotive wire and cable should reach 150 degrees). [0003] Although halogen...
