Abstract

The invention relates to a biodegradable high-performance modified particle material and a preparation method thereof. The biodegradable high-performance modified particle material is prepared from polylactic acid PLA, a natural organic plant fiber material, oxidized modified high-amylose starch, a composite plasticizer, a combined modifier, a functional aid, a modifier, modified carbon nanofibers and an inorganic filler. By carrying out melting reaction extrusion at 55-185 DEG C through a double-stage serial screw granulating unit, and carrying out mixing, reaction, extrusion, cooling, cutting, drying, sterilization and packaging, the particle material is obtained. Various household and industrial products, toys, stationery and electronic product shells are produced by adopting universal equipment such as extrusion molding, plastic uptake or injection molding units. The adopted raw materials are rich in source, the raw material cost is low, the process is simple, the production cost is low, and the prepared particle material has high strength and good antibacterial performance, anti-aging performance and hydrophobic performance and can meet the requirements of various biodegradable hard material products.

Description

technical field [0001] The invention belongs to the technical field of preparing biodegradable materials, and in particular relates to a biodegradable high-performance modified material particle with ceramic texture and a preparation method thereof. Background technique [0002] According to UNEP's "Legal Restrictions on Single-Use Plastics and Microplastics: A Global Review of National Laws and Regulations", "Single-Use Plastics: A Roadmap for Sustainable Development" and announcements on the websites of relevant Chinese government departments, the European Union, and international agencies: Of the 192 countries in the world, as of July 2018, 127 countries (about 66%) have enacted some form of national laws and regulations restricting single-use plastics and plastic bags (65 countries have no restrictions on single-use plastics and microplastics ), which include bans, levies, and waste management measures to enhance disposal, encourage reuse and recycling, and promote alte...
