This invention relates to the field of polymer materials technology, and discloses an anti-aging modified polylactic acid composite material and its preparation method. The material uses 100 parts by weight of polylactic acid resin as a base, and includes 0.5–3.0 parts by weight of a composite anti-aging additive and 0.2–0.8 parts by weight of a lubricant. The composite anti-aging additive is composed of an antioxidant, a hydrolytic stabilizer, and a light stabilizer in a mass ratio of 1:1:1. Preparation involves vacuum drying, high-speed mixing, and melt extrusion granulation. This invention utilizes the hydrolytic stabilizer to preferentially cap the carboxyl groups of polylactic acid, eliminating its consumption of hindered phenolic antioxidants and hindered amine light stabilizers. This achieves synergistic protection against heat-oxidation, damp heat, and ultraviolet aging, resulting in a mechanical retention rate of over 85% after aging, a yellowing index below 0.5, and good processing fluidity. It is suitable for biodegradable products with high weather resistance requirements.

The invention belongs to the field of flexible battery energy storage, and relates to a flexible self-supporting material and a preparation method and application thereof. The flexible self-supporting material comprises a carbon nanotube film, a Si / Ge film and a liquid metal film which are arranged in sequence.

This application provides a method for upgrading bauxite after grinding with mother liquor, belonging to the field of mineral processing. The method includes: grinding a mixed slurry of bauxite to be upgraded and circulating mother liquor to obtain an alkaline slurry with fully liberated aluminum and gangue minerals; using the circulating mother liquor as both a separation and auxiliary medium throughout the process, performing mineral processing and upgrading on the alkaline slurry to separate iron and silicon impurities in the circulating mother liquor medium, obtaining a concentrate slurry and a tailings slurry; sending the concentrate slurry to an alumina leaching process; and separating the tailings slurry to obtain circulating mother liquor and tailings byproducts. This application, through systematic process reengineering and closed-loop media design, successfully develops a bauxite pretreatment method that can be deeply coupled and seamlessly integrated with the Bayer process main process, avoiding interference from external media, and achieving efficient impurity removal under fully liberated mineral conditions.
