Problems solved by technology

Although the antibacterial materials and products prepared in this way have antibacterial function, there is a prominent problem: due to the limited compatibility between the antibacterial agent and the matrix, the antibacterial agent is easy to migrate and lose, resulting in the inability to maintain the long-term antibacterial function
However, the polymer antibact...

Embodiment 1

[0031] Polymer quaternary phosphonium salt antibacterial material of the present invention, its specific structural formula is:

[0032]

[0033]The preparation method of above-mentioned polymer quaternary phosphonium salt antibacterial material of the present invention, its detailed steps are as follows:

[0034] a. Using ethylene-vinyl alcohol copolymer EVOH (the mass fraction of vinyl alcohol is 16.6%) and 4-chlorobutyryl chloride as basic raw materials, first add 53.0g EVOH into a 500mL four-necked flask, then add 320mL xylene to dissolve, Stir and raise the temperature to 85°C. After the EVOH is completely dissolved, add 28.2g of 4-chlorobutyryl chloride dropwise. After the dropwise addition, react at a constant temperature of 85°C for 9 hours; after the reaction is completed, slowly pour the reaction solution into acetone for precipitation , the volume of acetone used is 5 times the volume of the reaction solution, and the obtained precipitated solution is placed at 2...

Abstract

The invention discloses a high polymer quaternary phosphonium salt antibacterial material and a preparation method thereof. The high polymer quaternary phosphonium salt antibacterial material is prepared by bonding halogenacylhalide type monomers onto macromolecules of an ethylene-vinyl alcohol copolymer (EVOH) through grafting reaction and further performing quaternary phosphonium reaction with trialkylphosphine. The high polymer quaternary phosphonium salt antibacterial material disclosed by the invention has the advantages of broad-spectrum, high-efficient and lasting antibacterial function and good safety, can be shaped and processed into products with the antibacterial function alone, and mixed with polyethylene, polypropylene and other non-polar resin and other types of resin for being shaped and processed into the products with the antibacterial function, and further has broad application prospects. The sterilization efficiency of the high polymer quaternary phosphonium salt antibacterial material prepared by the preparation method disclosed by the invention against escherichia coli, staphylococcus aureus and a variety of bacteria is more than 99%, and the mildew-resistant grade against aspergillus niger, aspergillus terreus and a variety of mildew is 1-0 grade.

Description

1. Technical field: [0001] The invention relates to a polymer antibacterial material and a preparation method thereof, in particular to a polymer quaternary phosphonium salt antibacterial material and a preparation method thereof. 2. Background technology: [0002] With the rapid development of the organic polymer material industry, materials and products such as plastics, fibers, rubber, coatings and adhesives are increasingly widely used. If these materials and products, such as plastic packaging products, do not have antibacterial function, bacteria, mold, etc. will corrode the packaged items and cause them to deteriorate or be damaged. The pollution and growth of bacteria, mold, etc. on the surface of the product will cause cross-infection to people who use and touch it, and pose a certain threat to health. Antibacterial materials are chemical substances that are highly sensitive to some bacteria, molds, fungi and other microorganisms. They not only have antibacterial f...
