Antibacterial flame-retardant polyolefin material as well as preparation process and application thereof

The invention discloses an antibacterial flame-retardant polyolefin material as well as a preparation process and application thereof. The antibacterial flame-retardant polyolefin material comprises the following raw material components in parts by weight: 80-90 parts of a thermoplastic elastomer, 1-3 parts of an antibacterial agent, 5-15 parts of a phosphorus-containing flame retardant, 2-15 parts of a nitrogen-containing flame retardant, 1-5 parts of a coupling agent, 0.2-2 parts of an antioxidant and 1-5 parts of a processing aid, the antibacterial agent is a mixture of a nano-silver-zinc composite antibacterial agent and chitin in a weight ratio of 1: (1-4); the average particle size of the nano silver-zinc composite antibacterial agent is 8-12 [mu] m. The polyolefin material has an excellent antibacterial effect on Escherichia coli, staphylococcus aureus and drug-resistant staphylococcus aureus, has a V0-level halogen-free flame-retardant effect, is excellent in processing performance, is used for prepar
