Example Embodiment
[0028] Example 1
[0029] The raw material components of rice straw and rice husk fiber-based wood-plastic composite profiles by weight percentage:
[0030] Melamine resin 3.5%, straw (rice husk) fiber 60%
[0031] Low density polyethylene 32% maleic anhydride, acrylic acid, styrene-ethyl copolymer 2%
[0032] Dimethicone 2.5%;
[0033] Such as figure 1 As shown, the preparation method of the above-mentioned rice straw and rice husk fiber-based wood-plastic composite profile is as follows:
[0034] (1) The melamine resin, rice straw and rice husk fibers are mixed with a conical twin-screw extruder at high speed and heated at a temperature of 200°C, and dehydrated to obtain modified rice straw and rice husk fibers;
[0035] (2) Mixing the modified rice straw and rice husk fiber obtained above with low-density polyethylene, solubilizer and lubricant, and extruding and granulating;
[0036] (3) Extruding the granulated particles, cooling and cutting;
[0037] (4) After sanding and po...
