Embodiment 1

[0079] A method for preparing a fabric with antibacterial and synergistic antibacterial adhesion functions, comprising the steps of:

[0080] (1) Soak 1g of fabric in 10g of ethanol and sonicate for 5 minutes, then rinse with deionized water, then replace the solvent with acetone and repeat the above operation, and finally use 20g of deionized water to sonicate for 10 minutes. The fabric was rinsed, dried under vacuum, and mounted on a glass slide.

[0081] (2) The fabric loaded on the glass slide is placed in a UV-ozone meter, and after 20min of fabric hydroxylation, the fabric containing hydroxyl is separated from the glass slide, then put into a flask, and 0.5g dissolved in 20g toluene is added A mixed solution of triethanolamine (TEA) and 0.1 g of 4-chloromethyl-phenyltrichlorosilane was stirred and reacted at 28° C. for 6 h at a rotation speed of 40 r / min. Finally, it was ultrasonically cleaned with a large amount of chloroform, acetone, methanol, and deionized water in ...

Abstract

The invention discloses a material with a function of antisepsis in cooperation with bacterial adhesion prevention and preparation and application thereof. According to the material with the functionof antisepsis in cooperation with bacterial adhesion prevention and the preparation and application thereof, based on the character that an organic antibacterial agent is lasting in antibacterial effect, the material surface is modified by means of the performance of antisepsis in cooperation with bacterial adhesion prevention of the special structure of organic molecules, wherein the super-hydrophobicity of vinyl silicone oil is used for reducing bacterial adhesion force to make bacteria attached to the material surface easy to remove; the property is used that an amphipathic vinyl nitrogen-containing compound can act on cytomembrane to result in release of materials in cells, so that bacterial growth is inhibited; the material surface which is modified by bonding the two compounds effectively inhibits bacterial adhesion, growth and reproduction. The prepared material has a good effect of antisepsis in cooperation with bacterial adhesion prevention and is lasting in effect of antisepsis in cooperation with bacterial adhesion prevention; in experiments, after the material (especially fabric) prepared by means of the method provided by the invention is washed for 30 times, 97% or higher of the antisepsis rate and 96% or higher of the bacterial adhesion prevention rate can still be maintained.

Description

technical field [0001] The invention belongs to the field of polymer chemical industry, and specifically relates to a material with antibacterial and synergistic antibacterial adhesion functions and its preparation and application. Background technique [0002] Fabrics are used frequently and in a wide range of applications, and can be used to make daily necessities, furniture items, medical supplies, and building materials. The fabric is in close contact with our skin, but as the fabric is exposed to the outside and the number of times it is used increases, bacteria tend to grow on the fabric. Bacteria multiply on fabrics on a large scale, causing discoloration, mildew, embrittlement and degradation of fabrics, thus seriously shortening its service life. At the same time, when the fabric adhered with bacteria is in contact with human skin, it will irritate the skin, induce various skin diseases such as dermatitis, and cause human health to be endangered. [0003] Therefor...
