Abstract
A method for preparing a bio-based composite using palm biomass powder as raw material, which belongs to the technical field of preparation methods for bio-based composites. During palm micropowder washing, 100 parts by weight of 600-1,200 mesh palm micropowder is placed in a reactor, and 400-500 parts by weight of acetone is added to the reactor in a 1:4 or 1:5 bath ratio; during surface treatment of palm micropowder, the reaction system after solvent displacement is heated to 80-100° C., and distillate is dehydrated with a 3A molecular sieve and then refluxed to a reactor; bio-based resin is compounded and extruded. At least one embodiment of the present invention solves the problem that use of palm as a biomass raw material leads to impurity migration and insufficient product performance due to high small oily molecule content.
