This invention provides a high-esterified persimmon pectin olive oil-based anti-fatigue beverage and its preparation method. The beverage comprises: extra virgin olive oil, high-esterified persimmon pectin, maltitol, freeze-dried peach powder, L-carnitine, vitamin E, hydroxytyrosol, and distilled water. The preparation process of this invention eliminates the need for processing aids such as emulsifiers and dispersants. High-esterified persimmon pectin is prepared through a pulsed electric field pretreatment-weak acid extraction process to obtain a highly active interfacial structure. This structure allows it to form a dense composite interfacial layer with other formulation components during two-stage shear emulsification, preferentially forming a stable oil-in-water emulsion system. This achieves long-term stable dispersion of the oil and water phases and masks the original spiciness and irritation of olive oil. Simultaneously, L-carnitine is added as a fatty acid metabolism support factor, and vitamin E and hydroxytyrosol are added as synergistic antioxidant components. The anti-fatigue effect is achieved through the synergistic effect of slow-release energy from the oil phase and interfacial structure regulation.

This invention relates to the field of materials processing technology, and discloses a processing aid for wood-plastic composites and its preparation method, to solve the problems of lubrication and extrusion in the processing of high wood flour content. The aforementioned processing aid, by weight, comprises 5-95 parts modified polysiloxane, 5-95 parts hydrocarbon wax, 5-95 parts fatty acid, 5-95 parts carboxylic acid ester, 5-95 parts fatty amide, 5-95 parts fatty alcohol, 5-95 parts metal soap, and 1-5 parts other additives. The processing aid of this application is applied to the processing and extrusion of wood-plastic composites, utilizing the complementary advantages of the lubrication effect of small molecule lubricants and the excellent properties of modified polysiloxane to prepare a composite lubricant. Simultaneously, the structural advantage of the polar groups in the polysiloxane has a coating effect on wood flour particles that have adsorbed other polar small molecules, while the long-chain alkyl portion achieves good compatibility with the polyolefin resin through entanglement, preventing the precipitation of other polar small molecules. The composite lubricant offers high cost-effectiveness and excellent processing lubrication and defect-free product extrusion appearance.

This invention discloses a phosphogypsum-based drawing masterbatch, its preparation method, and its application. The phosphogypsum-based drawing masterbatch comprises the following raw materials in parts by weight: 60-75 parts of modified phosphogypsum powder, 20-38 parts of carrier resin, and 0.5-2 parts of processing aid. The modified phosphogypsum powder is prepared by adding a composite modifier to phosphogypsum powder of three particle sizes (fine, medium, and coarse) and then dispersing them in a proportional manner. The composite modifier is composed of an aluminate coupling agent, a stearic acid dispersant, and a graft compatibilizer in a mass ratio of 1.5-2.5:1-1.5:0.5-1. This invention uses industrial by-product dihydrate phosphogypsum as raw material to digest phosphogypsum solid waste, solving the environmental problems of solid waste occupying land and causing water and soil pollution, while reducing the mining of mineral resources. By classifying phosphogypsum powder into three particle size specifications (fine, medium and coarse) for dense gradation and mixing with carrier resin, it is less likely to cause stratification and segregation, effectively improving the uniformity of material mixing and the mechanical properties of plastic products.
