The invention discloses a composite polymer self-sealing rubber material, a self-sealing rubber strip and a self-sealing safety tire. The composite polymer self-sealing rubber material is composed of a component A and a component B, the component A is prepared from the following components in parts by weight: 25 to 45 parts of natural rubber, 10 to 18 parts of butyl rubber, 40 to 65 parts of butadiene styrene rubber, 5 to 10 parts of thermoplastic elastomer, 10.0 to 14.5 parts of plasticizer, 14.0 to 22.0 parts of tackifier, 2.2 to 4.6 parts of anti-aging agent, 10 to 16 parts of filler and 4.5 to 7.0 parts of active aid; the component B is prepared from the following components in parts by weight: 70 to 90 parts of silicon rubber, 13 to 35 parts of polyurethane resin, 0.3 to 1.2 parts of silane coupling agent, 10.0 to 16.0 parts of plasticizer, 14.0 to 22.0 parts of tackifier, 2.0 to 4.5 parts of anti-aging agent, 6.0 to 14.5 parts of filler, 3.5 to 5.5 parts of nano zinc oxide and 2.3 to 4.5 parts of stabilizer; the composite high-molecular self-sealing rubber material has relatively good mechanical property, self-sealing property and high-temperature aging resistance; and the self-sealing safety tire is not easy to separate after being integrally vulcanized with the mother tire, so that the safe and reliable self-sealing safety tire is prepared.
