The invention discloses a flame-retardant type wood-plastic material. The material is prepared from, by weight, 60-70 parts of wood fibers, 11-16 parts of pentaerythritol, 21-28 parts of modified fire retardant, 21-28 parts of modified smoke inhibitor, 17-25 parts of polypropylene, 17-25 parts of high-density polyethylene, 8-13 parts of vermiculite, 5-9 parts of dioctyl phthalate, 6-13 parts of polyethylene glycol monostearate, 12-15 parts of unsaturated polyester resin, 5-9 parts of vinyl trimethoxy silane, 2-5 parts of luffa stems, 2-5 parts of polyethylene wax, 1-3 parts of PE wax, 1-3 parts of magnesia, 1-2 parts of graphite, 1-2 parts of herba taraxaci, 1-2 parts of ligusticum sinense olivers and 0.1-0.3 part of peanut oil. The wood-plastic material has high flame retandance and a good smoke inhabitation effect and does not release toxic and harmful substances at the high temperature, secondary harm to the human body is avoided, the heat insulation property is quite good, scalds to the human body are avoided, the quite good insulating property is achieved, and meanwhile the wood-plastic material is compact in material, good in mechanical performance and quite durable.
