Embodiment 1
[0098] The preparation method of the wear-resistant and impact-resistant plastic wood material prepared from waste PET bottles comprises the following steps:
[0099] (1) Dissolving the high-functionality hydroxyl polyether in anhydrous ethanol solution; then evenly spraying on the surface of the wood powder of the formulation amount, stirring and mixing evenly, and drying in vacuum until the volatile content is less than 2% to obtain the modified wood powder I; wherein, The mass ratio of high-functionality hydroxyl polyether to absolute ethanol is 1:3;
[0100] (2) The preparation method of waste PET bottle chip alcoholylate is as follows:
[0101] S1: Wash the recovered waste PET plastic bottles, first use 2% sodium hydroxide solution for alkali washing, and then wash twice with water; then dry until the volatile content is less than 2%, and crush it to a size of 2mm;
[0102] S2: Put the crushed raw materials in S1 into the reactor and react with alcoholysis with trihydric...
Embodiment 2
[0115] The preparation method of the wear-resistant and impact-resistant plastic wood material prepared from waste PET bottles comprises the following steps:
[0116] (1) Dissolving the high-functionality hydroxyl polyether in anhydrous ethanol solution; then evenly spraying on the surface of the wood powder of the formulation amount, stirring and mixing evenly, and drying in vacuum until the volatile content is less than 2% to obtain the modified wood powder I; wherein, The mass ratio of high-functionality hydroxyl polyether to absolute ethanol is 1:2.5;
[0117] (2) The preparation method of alcoholyzate of waste PET bottle flakes is the same as that of Example 1 (in the preparation process of alcoholyzate, what S2 step adopted is trimethylolpropane, and the mass ratio of its consumption and waste PET bottle flakes is 3.5:1 ), the following embodiment 3 is the same;
[0118] The waste PET bottle chip alcoholylate and modified wood powder I were mixed and stirred evenly at r...
Embodiment 3
[0126] The preparation method of the wear-resistant and impact-resistant plastic wood material prepared from waste PET bottles comprises the following steps:
[0127] (1) Dissolving the high-functionality hydroxyl polyether in anhydrous ethanol solution; then evenly spraying on the surface of the wood powder of the formulation amount, stirring and mixing evenly, and drying in vacuum until the volatile content is less than 2% to obtain the modified wood powder I; wherein, The mass ratio of high-functionality hydroxyl polyether to absolute ethanol is 1:3.5;
[0128] (2) Mix waste PET bottle flake alcoholylate and modified wood flour I at room temperature and stir evenly, then extrude and pelletize through a twin-screw extruder to obtain modified pellets I, and extrude and pelletize The process conditions are: barrel temperature is 200°C, screw speed is 300rpm;
[0129] (3) Stir the high-impact ABS resin, polyester hot-melt adhesive, and graphite powder evenly at room temperatur...
