Problems solved by technology

The existence of microorganisms can also lead to the degradation of fabric fiber macromolecules, causing brittleness, discoloration, mildew and other phenomena in the fabric, affecting the appearance and color of clothing and decorations; for some military items, such as parachutes, gun coats, tents, etc., It will endanger safety, affect combat effectiveness, and the consequences will be unimaginable; in order to solve the above problems, a feasible way will be able to kill antibacterial agents that are harmful to human body and clothing to treat fabrics
[0003] Traditional antibacterial agents mainly use quaternary ammonium salt compounds. Quaternary ammonium salt disinfectants refer to disinfectants made of quaternary ammonium compounds with disinfection effect as active ingredients. It is a representative of cationic surfactants. Ammonium salt compounds can adsorb negatively charged bacteria, have good bactericidal effect, and are widely used in the world; single-chain quaternary ammonium salts gradually show some shortcomings, such as narrow killing spectrum, bacteria have developed drug resistance and It has a high MIC value for bacteria, etc.; at present, in the antibacterial of textiles, it is first necessary to consider that ordinary quaternary ammonium salts are elution-type and easy to elute
However, if siloxane is introduced into the quaternary ammonium salt structure to obtain the organosilicon quaternary ammonium salt, its performance can be greatly changed; there have been many reports on gemini quaternary ammonium salt antibacterial agents, and they have also shown relatively Excellent antibacterial performance and wide bactericidal range, but it is still a small molecule quaternary ammonium salt, which has the common disadvantages of small molecule quaternary ammonium salts, and the effect of applying it on fabrics as an antibacterial finishing agent is not ideal

Abstract

The invention discloses a non-dissolution type antibacterial finishing agent and a preparation method thereof. The non-dissolution type antibacterial finishing agent comprises the following componentsin parts by weight: quaternary ammonium salt antibacterial monomers, hexafluorobutyl acrylate, dodecyl sodium carboxymethyl imidazoline acetate, an initiator, a cross-linking agent, a catalyst, an emulsifier and water. Based on a molecular coupling effect of silane, the method makes full use of the property that a trimethoxy functional group on an organosilicon molecule not only can react and combine with inorganic materials such as glass, silicon and metal, but also can be directly combined with organic molecules such as fiber resin and can be fixed on the surface of a general object in a root binding mode, curing long-acting disinfection is achieved, especially an inhibition rate on escherichia coli and staphylococcus aureus is high, the hexafluorobutyl acrylate is introduced, a fluorine-containing group can reduce the surface energy of the antibacterial finishing agent, and compared with a traditional gemini quaternary ammonium salt antibacterial agent, the non-dissolution type antibacterial finishing agent is not likely to dissolve out, firm and durable in combination with fibers, obvious in antibacterial effect and good in antibacterial effect after being washed for many times.

Description

technical field [0001] The invention relates to a non-elution type antibacterial finishing agent and a preparation method thereof. Background technique [0002] In the daily life of human beings, it is inevitable to come into contact with various microorganisms. These microorganisms can directly or indirectly cause harm to the human body, and microorganisms can multiply rapidly under certain environmental conditions. Grease, dander, or the decomposed substances of the fabric itself multiply rapidly as nutrients, forming a large number of harmful bacteria and spreading through the air, causing diseases and affecting people's daily life. The existence of microorganisms can also lead to the degradation of fabric fiber macromolecules, causing brittleness, discoloration, mildew and other phenomena in the fabric, affecting the appearance and color of clothing and decorations; for some military items, such as parachutes, gun coats, tents, etc. It will endanger safety, affect comba...
