Embodiment 1
[0024] The furfural slag derived from wheat straw is washed and crushed to 200 mesh, and dried until the moisture content is lower than 1%. Put 50 parts by weight of dried furfural slag, 10 parts of glass fiber, 5 parts of maleic anhydride grafted PE, 5 parts of maleic anhydride, and 5 parts of titanate coupling agent into a mixer for high-speed cold mixing for 10 minutes at a speed of 400 rpm , and then heated to a temperature of 90° C. for 20 minutes to obtain modified furfural slag. Add 100 parts of modified furfural slag, 60 parts of recycled thermoplastics, 2 parts of EBS, 3 parts of calcium stearate, and 10 parts of iron oxide red to a parallel twin-screw extruder for extrusion blending and granulation to obtain wood For plastic primary materials, the speed is 400 rpm and the temperature is 160°C. Put the granulated primary material into the conical twin-screw extruder, according to the preset barrel temperature and die head temperature, the main engine speed is 20 rpm,...

[0026] The furfural slag derived from wheat straw is washed and crushed to 200 mesh, and dried until the moisture content is lower than 1%. Put 50 parts by weight of dried furfural slag, 10 parts of nano-calcium carbonate, 5 parts of acrylic acid grafted PVC, 5 parts of maleic anhydride, and 5 parts of titanate coupling agent in a mixer for high-speed cold mixing for 10 minutes at a speed of 400 rpm. Afterwards, heat it to a temperature of 90°C and keep it warm for 20 minutes to obtain modified furfural slag. Add 100 parts of modified furfural slag, 60 parts of recycled thermoplastic PVC, 2 parts of EBS, 3 parts of calcium stearate, and 10 parts of iron oxide red to a parallel twin-screw extruder for extrusion blending and granulation to obtain wood For plastic primary materials, the speed is 400 rpm and the temperature is 160°C. Put the granulated primary material into the conical twin-screw extruder, according to the preset barrel temperature and die head temperature, the m...
