Example Embodiment
[0034] Example 1: Preparation of long-fiber reinforced masterbatch for high-rigidity, creep-resistant wood-plastic products
[0035] Such as figure 1 As shown, an impregnation mold includes a melt inlet channel 1; a fiber bundle inlet channel 2; a fiber bundle preheating sleeve 7; a melt impregnation cavity 3; a lattice tension roller 4; an impregnating material outlet die 5; Melt immerses the cavity 6 in the cavity.
[0036] a. 30Kg glass fiber (362, Jushi Fiber Factory) is preheated by the fiber bundle preheating sleeve 7 and then continuously introduced into the cavity of the fiber impregnation mold. The fiber bundle enters the melt impregnation cavity 3 through the fiber bundle inlet channel 2;
[0037] b. After 65Kg polypropylene (V30G, Hainan Petrochemical), 0.5Kg KH-550, 5Kg polypropylene grafted with maleic anhydride, 0.2Kg antioxidant 1010, and 0.1Kg antioxidant 168 are premixed in the mixer , Adding the extruder to mix and melt into a melt, the melt enters the melt impreg...
