description The invention belongs to the field of rubber sealing strips, and particularly relates to a low-compression permanent deformation low-temperature-resistant EPDM sealing strip and a preparation method and application thereof. The low-compression permanent deformation low-temperature-resistant EPDM sealing strip is prepared from the following raw materials in parts by weight: 100 parts of ethylene propylene diene monomer, 20 to 50 parts of carbon black, 5 to 10 parts of modified boehmite, 2.0 to 5.0 parts of tetrabutyl titanate, 0.5 to 1.0 part of sodium citrate, 3.0 to 5.0 parts of zinc oxide, 1.0 to 2.0 parts of stearic acid, 3.0 to 5.0 parts of polyethylene glycol 6000, 30 to 50 parts of softening plasticizer, 0.5 to 1.0 part of accelerant MMB-80, 1.5 to 2.0 parts of accelerant CBS-80, 0.5 to 1.0 part of an accelerant ETU-80, 0.5 to 1.0 part of an accelerant TMTD-80, 1.0 to 1.5 parts of an anti-aging agent 1010 and 1.0 to 1.5 parts of a vulcanizing agent S-80. According to the low-compression permanent deform
