Abstract

The invention provides a humic acid composite material and a preparation method thereof. The humic acid composite material is formed by mixing of the following components by weight: 1%-60% of humic acid, 10%-99% of a polymer, 0%-10% of a compatibilizer, 0%-10% of a plasticizer, 0%-12% of a lubricant, and 0%-1.5% of an antioxidant. In the invention, the abundant and cheap renewable degradable biological resource humic acid is adopted as a substrate, at least one polymer is compounded, and melt blending of the polymer is conducted to form the composite material. Therefore, the application scope of humic acid is broadened, its utilization rate is enhanced, and insufficiency of petroleum based polymer resources is relieved, so that the humic acid composite material has broad industrial application prospects. With a low production cost, the humic acid composite material provided in the invention has mechanical properties meeting the requirements of actual use and is degradable.

Description

technical field [0001] The invention belongs to the technical field of biomass composite polymer materials, and in particular relates to a humic acid composite material and a preparation method thereof, which expands the application field of humic acid. Background technique [0002] Humic acid is a kind of amorphous and multi-molecular-weight biomass macromolecule widely present in soil, river mud, marine sediment, peat, weathered coal and lignite. The complex and stable heterogeneous organic matter formed by copolymerization with amino acids is a rich and cheap renewable and degradable biological resource. As an organic raw material, humic acid is widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, chemical industry, building materials, medicine, sanitation, and environmental protection. The main products developed in China include fertilizers, pesticides, veterinary drugs, drought-resistant agents, feed additives; pharmaceuticals, hea...
