[0024] The embodiment of the present invention provides a method for extracting 3D printing thermoplastic materials from wood, the method is carried out according to the following steps:
[0025] 1. Prepare the extract: take benzene or benzene derivatives and ethanol to mix to obtain the extract, the volume ratio of the ethanol and benzene or benzene derivatives is 1: (1-3.5);
[0026] 2. Put the wood powder and the extract prepared in step 1 into the extraction device to extract and obtain the extraction residue; 3. Prepare a buffer solution, the pH of which is 3.8-4.2, to step 2 to obtain Add the buffer solution to the extraction residue to obtain a mixed solution, and stir at 70°C-80°C until the mixed solution turns white to obtain an oxidized product;
[0027] 4. Centrifuge the oxidized product obtained in step 3, then wash it with distilled water to neutrality, then wash it with acetone, and finally vacuum-dry the washed product to obtain cellulose;
[0028] 5. Prepare a...
