Abstract
The invention discloses a method for extracting a 3D printing thermoplastic material from wood, belongs to the technical field of 3D printing and in particular relates to the technical field of extracting 3D printing materials from wood. The method for extracting the 3D printing thermoplastic material from wood comprises the following steps: I, preparing an extraction liquid, namely mixing benzeneor a benzene derivative with ethanol so as to obtain the extraction liquid; II, putting wood flour and the extraction liquid into an extraction device, and performing extraction so as to obtain extraction residues; III, preparing a buffer solution, putting the extraction residues into the buffer solution, and stirring at 70-80 DEG C till a mixed liquid is whitened so as to obtain an oxidation product; IV, performing centrifugal separation on the oxidation product, washing with distilled water till being neutral, further washing with acetone, and finally performing vacuum drying on the washingproduct so as to obtain comprehensive cellulose; V, preparing an alkali solution, mixing the alkali solution with the comprehensive cellulose, and performing a series of treatment in a reaction kettle, thereby obtaining the thermoplastic material. The material prepared by using the method can be applied to 3D printing.
