Abstract
A preparation method for a long-acting natural multifunctional additive. A natural filler is coated with a modified polymer; the modified polymer is obtained by modifying any one or more than two of a biodegradable polymer, a water-soluble polymer, polyvinyl chloride, polyamide, polyphenylene sulfide, melamine resin, polyolefin, polyhydroxyalkanoate, a styrene block copolymer, chlorinated polyvinyl chloride, urea-formaldehyde resin, polyurethane, and chitosan; and the natural filler is shell powder or eggshell calcined at high temperature, any one or more than two of calcium oxide, calcium hydroxide, magnesium oxide, magnesium hydroxide, and purified Hermetia illucens pupa shell powder, or a compound of nanoparticles and calcined shell powder or eggshell powder. By adoption of the preparation method disclosed by the present invention, the cost is low, and part of raw materials are recycled wastes; the antibacterial property of the natural filler is long-acting, and the natural filler is easy to store; and the preparation method can be applied to various processing techniques, or the addition or adjustment of health care products.
Description
Preparation method and application of long-acting natural multifunctional additive
BACKGROUND
The invention belongs to the technical field of materials, relates to the sterilization additive technology, and particulany relates to preparation method and application of long-acting natural multifunctional additive.
It is estimated that the market value of the giobal additive market will reach 62.5 billion US dollars in year 2022. Because additives can be used in various industries, the to olobai market share of plastic additives is highly concentrated in comprehensive enterprises, including raw material production to plastics, building manufacturing and even food. There are large industry participants operating globally, including DuPont, PolyOne, Dow Chemical Company, Evonik and BASF. Because antibacterial additives can give products antibacterial and bacteriostatic function, they are believed to have a good market prospect. Harmful bacteria are common in nature, and interfering with human life. The proliferation of harmful bacteria threatens human health, and inhibiting their growth can reduce the occurrence of diseases.
Among metal ion antibacterial agents, silver ion antibacterial agents are the most studied at present, because silver has the strongest bactericidal ability. Metal oxide antibacterial agent belongs to photocatalyst, which is a kind of substance that does not change itself under the irradiation of light, but can promote chemical reaction, and convert light energy existing in nature into energy needed for chemical reaction. Common photocatalytic materials include TiO2 and ZnO, among which TiO2 is the most representative. Organic antibacterial agents are mostly obtained by chemical synthesis, including organic acids, esters, quaternary ammonium salts, biguanides, yeasts, rtitrile,s, pyridines, phenols, aldehydes, ethers, peroxides, halogens, imidazoles, thiazoles, etc. Organic antibacterial agents usually have high antibacterial performance, but they also have some disadvantages such as poor heat resistance, poor antibacterial durability or biological toxicity. Natural antibacterial agents are extracted and refined from animals and plants, and most of them are polysaccharides, polypepticles and glycopeptide polymers, including chitosan, prolamine, cinnamon oil and Lohan tar, etc., which have the advantages of excellent weather resistance, low toxicity and being safe for using. Chitosan is the deacetylate.d product of chitin refined from the skins of crabs, shrimp shells, shellfish and insects. The main disadvantages of natural antibacterial a poor heat resistance and short duration of efficacy: which is the main development direction of antibacterial additives in the future.
To sum up, most of the existing antibacterial agents are expensive, and some of them are harmful to the environment or have biological toxicity: which does not conform to the modern concept of environmental protection and health. In addition, most antibacterial agents will reduce their original antibacterial activity with the change of time to or the influence of the environment. On the other hand, most antibacterial agents will affect the physical properties of products: which is due to the poor mechanical properties of antibacterial agents and the difficulty in dispersing antibacterial agents.
