Abstract
The invention relates to a wood-plastic composite material and a preparation method thereof. The wood-plastic composite material is prepared from the following raw materials in parts by weight: 30-35 parts of high-density polyethylene, 20-25 parts of nylon PA66, 30-35 parts of straw powder, 10-12 parts of calcined loess powder, 10-12 parts of light calcium carbonate powder, 8-10 parts of sodium metasilicate, 3-4 parts of stearic acid, 5-8 parts of tributyl citrate, 1-2 parts of catechol, 2-3 parts of soybean oil, 1-2 parts of urotropine, 4-6 parts of n-butyl methacrylate, 3-5 parts of polyethylene wax, 2-3 parts of triethoxy vinyl silane, 8-10 parts of sepiolite powder, 2-3 parts of sulfurized isobutylene, 2-3 parts of alum powder and 5-8 parts of nano brick slag powder. According to the invention, nylon is adopted as one of the main raw materials, so that the strength of the wood-plastic composite material is greatly improved. An improved process is adopted, and straw powder is wrapped firstly, so that the moisture absorption performance of straw is greatly reduced, the dispersity is greatly improved, the quality of wood-plastic profiles is greatly improved, and a produced profile has a smooth surface and high strength.
