Biodegradable high-performance particle material with ceramic texture and preparation method thereof

Abstract

The invention relates to a biodegradable high-performance particle material with ceramic texture and a preparation method thereof. The biodegradable high-performance particle material is prepared from biologically fermented PBS, a modified natural organic plant fiber material, oxidized modified high amylose, a composite plasticizer, a functional aid, a modifier and modified high-density minerals. Melting reaction and extrusion are performed at 55-160 DEG C by virtue of a double-stage serial screw granulating unit, and mixing, reacting, extruding, cooling, cutting, drying, sterilizing and packaging are carried out to obtain the particle material. Various daily supplies are produced by adopting universal equipment such as extrusion molding, plastic uptake or injection molding units and the like. 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 high-performance particle material has high strength and good antibacterial property and hydrophobic property, achieves the ceramic texture and can meet the increasing requirements of people for consumption upgrading of daily supplies.

Description

technical field [0001] The invention belongs to the technical field of preparing biodegradable materials, and in particular relates to a biodegradable high-performance particle material with ceramic texture and a preparation method. Background technique [0002] With the rapid development of the economy, the proliferation of disposable plastic products poses a major threat to the living environment of human beings, and a large number of plastic wastes cause serious pollution to water resources and soil resources. Actively preventing and preventing the proliferation of disposable plastic products has become China and the world. The consensus of most countries, and biodegradable plastics is undoubtedly an important measure to solve the above problems. Some environmentally friendly materials currently on the market are almost all at the expense of one another, and cannot meet the shortcomings of safety, hygiene, convenience, environmental protection, and low cost at the same ti...

Problems solved by technology

[0005] Chinese patent CN106084701A discloses a degradable plastic, which is made of the following raw materials in proportion by weight: 60-65 parts of starch, 50-55 parts of polycaprolactone, and 70-75 parts of polybutylene succinate , 75-80 parts of polyhydroxyalkanoate, 20-30 parts of polyvinyl alcohol, 4-6 parts of chitin, 7-15 parts of polyaspartic acid, 15-20 parts of cellulose, 10-15 parts of polypropylene, phenolic 13-16 parts of resin, 2-4 parts of diatomaceous earth, 20-30 parts of asbestos, 15-20 parts of carbon black, 8-10 parts of phthalates, 35-40 parts of silicone rubber, 12-14 parts of isononyl ester, 5-8 parts of zinc chromate and 12-16 parts of organotin. Although the material can be fully degraded, its strength is low, the antibacterial performance is poor, and the hydrophobic performance is poor, which cannot meet the requirements of daily necessities materials. Requirements, such as shelves for bath towels in the bathroom, trays for toiletries, etc.

[0006] Chinese patent CN107083075A discloses a biodegradable straw disposable material, which is composed of the following raw materials: straw powder, starch, fiber, glycerin, bioplastic, release agent, accelerator, water, although the material can achieve biodegradation, but There are still problems of insufficient strength, insufficient toughness, easy breakage, poor hydrophobicity, and poor antibacterial performance, which cannot meet the needs of daily necessities materials;

Although this material also discloses adding plant fibers to improve strength, its strength still cannot meet the requirements, and its hydrophobicity and antibacterial performance are poor, it does not have metallic luster, and it is not beautiful enough.

[0009] Based on the poor performance of the degradable particle materials developed in the existing technology, they cannot meet the needs of the degradable particle materials required by the high-end consumer market. Composite modified degradable particle high-performance particle material that can meet the requirements of the high-end consumer market. This invention is an inventive technology in this series of work
