The invention belongs to the technical field of high polymer materials, and relates to a flame-retardant polyurethane elastomer, and a preparation method and application thereof. The flame-retardant polyurethane elastomer provided by the invention is mainly prepared from the following raw materials in parts by weight: 10-100 parts of unsaturated polyurethane raw rubber, 5-50 parts of a vulcanization system, 5-80 parts of a halogen-free flame retardant, 1-30 parts of a smoke suppressant, 0.01-2 parts of an antioxidant, 0.01-2 parts of an anti-aging agent, 0.01-2 parts of a stabilizer, 0.01-2 parts of an anti-hydrolysis agent, 0.01-4 parts of a rat-proof master batch, 0.01-4 parts of a termite-proof master batch and 0.01-8 parts of a foaming agent. The polyurethane elastomer has excellent flame retardant property and low smoke characteristic, good processability and excellent mechanical property, is safe, nontoxic, green and environment-friendly, and has long service life. |
