The invention discloses a wood-plastic composite material based on coconut branch leaf fiber. The composite material contains coconut branch leaf fiber, recycled thermoplastic resin, calcium carbonate, and is supplemented by relevant additives. Under a specific process formula, reverse rolling is adopted. The preparation method of coconut branch leaf fiber powder prepared by feeding and first cutting and then grinding, and then through the production process of low-speed and high-speed mixing, high temperature and high pressure granulation, and controlling the temperature of each zone. Material, the production process is smooth, the product strength, toughness, bending failure load, screw holding force, impact resistance, water absorption dimensional change rate and other indicators have been improved, and the deformation, cracking, brittleness and other phenomena in practical applications have been greatly improved. |
