[0017] Another aspect of the present invention provides a method for preparing the above-mentioned high-strength temperature-resistant wood-plastic composite material, the method comprising: (1) first mixing the high-strength temperature-resistant agent uniformly, and then adding plant materials and mixing uniformly to obtain a first mixture; 2) Mix the first mixture with the coupling agent uniformly, then add polyethylene, ABS resin, lubricant and antifungal agent, and continue mixing; (3) Add the mixture obtained in step 2 to a single screw extruder Pelletizing to obtain wood-plastic composite material masterbatch; (4) putting the wood-plastic composite material masterbatch into a twin-screw extruder to process into a plate.
[0018] In the present invention, the high-strength temperature-resistant agent is uniformly mixed first, so that the diatomaceous earth and nano-zirconia are fully mixed, and then mixed with the plant material, thereby improving the dispersibility of the h...
