[0078] Such as image 3 Shown, the preparation method of composite material of the present invention comprises the following steps:
[0079] a) Primary mixing step: Add ABS, PVB, SBS, SMN resin and lignocellulose to the horizontal mixer 1 of the silo device and mix and stir until uniformly obtained raw material mixture;
[0080] b) Secondary mixing step: Put the above-mentioned raw material mixture into the hopper 3 of the single-screw extruder through the transmission device 2, add diatomaceous earth, nano-calcium carbonate, JC-G530C reinforcing agent for mixing and stirring, and pass through the single-screw extruder 4 Extrusion of semi-finished composite materials;
[0081] c) Three mixing steps, introducing the semi-finished composite material into the twin-screw machine hopper 5, adding PE and EVA for mixing and stirring, and extruding through the twin-screw machine 6 to obtain the cold-resistant and high-temperature-resistant composite material.

Embodiment 1
[0103] One mixing step, add 15 parts of ABS (Samsung ABS0150), 5 parts of PVB (Shanghai Sixi Chemical Co., Ltd.), 12 parts of linear SBS (Taiwan LGSBSPB-575), 25 parts of SMN resin, 0.3 parts of lignocellulose were mixed and stirred until uniform to obtain a raw material mixture; the temperature of the first mixing was room temperature, and the time was 5 minutes.
[0104] Secondary mixing step, putting the raw material mixture into the hopper of a single-screw extruder through a transmission device, adding 10 parts of diatomaceous earth, 17 parts of NPCC-701 modified nano-resin calcium carbonate (Warner Nano Materials Co., Ltd.) 10 parts of JC-G530C reinforcing agent (Jiuchuan Nano Material Technology Co., Ltd.) were mixed and stirred and the semi-finished composite material was extruded through a single-screw machine; the temperature of the second mixing step was controlled at 42°C to 53°C for 3 minutes.
[0105] Three mixing steps, introducing the semi-finished composite ma...
Embodiment 2
[0107] In one mixing step, add 12 parts of ABS, 10 parts of PVB, 10 parts of linear SBS, 20 parts of SMN resin, and 0.5 part of lignocellulose into the horizontal mixer of the silo device and mix and stir until uniformly obtained raw material mixture; The temperature was room temperature and the time was 8 minutes.
[0108] Secondary mixing step, put the raw material mixture into the hopper of the single-screw extruder through the transmission device, add 20 parts of diatomaceous earth, 15 parts of NPCC-701 modified nano-resin calcium carbonate, and 8 parts of JC-G530C to enhance The mixture is mixed and stirred and the semi-finished composite material is extruded through a single-screw machine; the temperature of the secondary mixing step is controlled at 42° C. to 53° C., and the time is 4 minutes.
[0109] Three mixing steps, introducing the semi-finished composite material into the hopper of a twin-screw extruder, adding 27 parts of LLDPE and 10 parts of EVA for mixing and...
