Abstract

The invention relates to a biodegradable composite modified film / bag particle material and a preparation method thereof. The biodegradable composite modified film / bag particle material is prepared from a biodegradable polyester compound, a natural organic plant fiber material, oxidation modified high amylose, a composite plasticizer, a combined modifier, a functional aid, a modifier, modified carbon nanofibers and an inorganic filler. The particle material is obtained by melting reaction extrusion at 55-170 DEG C by virtue of a double-stage serial screw granulating unit, and carrying out mixing, reacting, extruding, cooling, cutting, drying, sterilizing and packaging. Various thin films, bags, disposable gloves, tablecloth, aprons, raincoats and other products are produced through universal equipment such as a film blowing machine and a casting machine unit. The adopted raw materials are rich in source, low in cost, simple in process and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of preparing biodegradable materials, and specifically relates to a biodegradable composite modified film / bag particle material and a preparation method thereof. Background technique [0002] Actively preventing and stopping the flood of disposable plastic products has become the consensus of most countries in China and the world. The degradable plastic manufacturing industry has keenly captured this policy trend. According to statistics from Huaan Securities, 36 companies are building or planning to build degradable plastic projects, with a total new capacity of 4.405 million tons. Many large companies in the food and drink industry have pledged to eliminate plastic cutlery over the past year as they adapt to changes in consumer expectations and legislation; [0003] Therefore, with the orientation of being recyclable, easy to recycle, and degradable, develop and promote plastic products and alternative p...
