Abstract

The invention relates to an antibiotic finishing agent mainly used in textile coatings. A self-crosslinked organosilicon modified polymer is prepared through an emulsion polymerization method with an acrylate monomer, styrene, an organosilicon cross-linking agent and an alkenyl amine monomer as polymerization monomers and polymerizable maleic anhydride fatty alcohol polyoxyethylene ether monoester as an emulsifier, and a silver salt is added to an emulsion for a complexation reaction in order to prepare the textile finishing agent having antibiotic and antistatic functions. The finishing agent has the characteristics of good water resistance, good low temperature resistance and the like, has the durable antibiotic and antistatic functions, and can be used for the functional finishing of the textile surfaces.

Description

technical field [0001] The invention relates to an antibacterial finishing agent and belongs to the field of textile chemistry. Background technique [0002] Antibacterial agents currently used in textiles are generally divided into three categories: natural antibacterial agents, organic antibacterial agents and inorganic antibacterial agents. [0003] Inorganic antibacterial agents mainly refer to the preparation of silver and other metals or metal ions that have antibacterial ability in themselves and are dispersed on inorganic carriers. Currently commercialized inorganic antibacterial agents are mostly silver-based antibacterial agents. There are problems in the uniform dispersion of silver-loaded antibacterial agents in the medium, long-term aging, self-migration in the carrier, and slow release. These problems are mainly caused by the inherent characteristics of inorganic mineral carriers such as adsorption performance and specific surface area. Inorganic antibacteria...
