Embodiment 1
[0031] (1) Prepare a mixture of 2-amino-2-ethyl-1,3-propanediol and zinc stearate. In a reactor with a temperature of 170°C and a rotation speed of 200 rpm, add 100 part of ABS resin, after the ABS resin is completely melted, dropwise add a mixed solution containing 40 parts of 2-amino-2-ethyl-1,3-propanediol and zinc stearate mixture (2-amino-2-ethyl- 1,3-Propanediol and zinc stearate (mass ratio 1:0.05), after the dropwise addition, react for another 0.5 hour to end the reaction and obtain the ABS graft.
[0032] (2) drop into ABS resin in mixing equipment, then add 100 mesh bamboo powder, above-mentioned interface modifier ABS graft, lubricant, formula is by mass parts 100 parts of ABS resin, 30 parts of bamboo powder, interface modification 5 parts of agent, 2 parts of lubricant stearic acid. After mixing evenly, the ABS-based wood-plastic composite material was prepared through a twin-screw extruder, and the test results of its mechanical properties are shown in Table 1...
Embodiment 2
[0036] (1) A mixture of ethanolamine and cadmium acetate is made into a mixed solution. In a reactor at a temperature of 200°C, with a rotation speed of 100 rpm, 100 parts by mass of ABS resin is added. After the ABS resin is completely melted, 25 parts of ethanolamine and cadmium acetate are added dropwise. The mixed liquid of the cadmium acetate mixture (ethanolamine and cadmium acetate in a mass ratio of 1:0.1), after the dropwise addition, was reacted for another 2 hours, and the reaction was terminated to obtain the ABS graft.
[0037] (2) drop into ABS resin in mixing equipment, add 80 order wood flours, above-mentioned ABS graft, lubricant again, formula is by mass parts 100 parts of ABS resins, 50 parts of wood flours, 8 parts of interfacial modifiers, Lubricant silicone oil 0.5 parts. After mixing evenly, the ABS-based wood-plastic composite material was prepared through an open mill, and the test results of its mechanical properties are shown in Table 2.

Embodiment 3
[0041] (1) Dissolve the mixture of 2-aminophenol and itaconic acid to form a mixed solution. In a reactor at a temperature of 260°C, with a rotation speed of 20 rpm, add 100 parts by mass of ABS resin. After the ABS resin is completely melted, Add dropwise 15 parts by mass of a mixture of 2-aminophenol and itaconic acid (2-aminophenol and itaconic acid in a mass ratio of 1:0.05). After the addition is complete, react for another 0.5 hour to end the reaction and obtain the desired graft product.
[0042] (2) Put ABS resin into the mixing equipment, then add 60 mesh rice bran, the above-mentioned interface modifier ABS graft, lubricant, and the formula is 100 parts of ABS resin in parts by mass, 80 parts of rice bran, and 10 parts of interface modifier. 1 part, lubricant polyethylene wax 1 part. After mixing evenly, the ABS-based wood-plastic composite material was prepared by an internal mixer, and the test results of its mechanical properties are shown in Table 3.
