Abstract

The invention provides a plant-based material. The plant-based material is prepared from the following components in percentage by mass: 60-85% of polylactic acid; 7%-15% of toughening resin; 5%-30% of coffee grounds; and the balance of auxiliaries. The sum of the mass percentages of the components is 100%. Eccentric rotor extensional rheological plasticizing extrusion equipment is adopted to process PLA, PBAT or PBS, coffee grounds, other auxiliaries and the like according to a certain proportion to obtain a modified material or product.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to plant-based materials and their preparation methods and applications. Background technique [0002] Coffee is one of the most popular beverages and one of the most widely traded commodities internationally. Coffee grounds are the by-products left after coffee is extracted from coffee beans, accounting for about 2 / 3 of the weight of dry coffee beans. Coffee grounds are rich in oil, sugar and protein, cellulose, acids (amino acid, chlorogenic acid, other fatty acids), etc., of which coffee oil content is about 14%. Coffee oil contains 4 main fatty acids, accounting for 95.25% of the total, respectively linoleic acid 34.79%, oleic acid 9.85%, palmitic acid 42.12%, stearic acid 8.49%. Coffee grounds have a strong coffee aroma, and the volatile fat is the main source of coffee aroma, which emits about forty aromatic substances. And its dyeing is very strong. At present, the appli...
