Abstract

The invention discloses an antibacterial polymer material which is polymerized by a plurality of components including antibacterial oligomer. The specific components comprise 30-99.5wt percent of unsaturated double bond monomer, 0.01-50wt percent of unsacturated double bond antibacterial oligomer, 0-10wt percent of hydrophilic monomer, 0.01-5.0wt percent of polymerization initiator and 0-80wt percent of fillings. The antibacterial polymer material of the invention is safe to the health of people and has long antibacterial performance and the antibacterial rates of the invention to staphyloccocus aureus rosenbach and escherichia coli are both more than 99percent. The invention is applicable for medical treatment and hygiene industries, including the wound dressing material, dental recovery materials used in dentistry (such as tooth bonder, tooth recovery coating, tooth recovery substrate and tooth filling materials, etc.), surgery seam and materials for daily use, etc.

Description

technical field [0001] The invention relates to a polymer, in particular to an antibacterial polymer material with permanent antibacterial properties. Background technique [0002] Antimicrobial polymer materials can generally be obtained by the following two methods: [0003] 1. It is the simplest method to directly add organic small molecule antibacterial agents or inorganic antibacterial agents to polymer materials. What is used more now is to directly add inorganic antibacterial agents, such as zeolite materials containing metal ions (silver ions, copper ions, zinc ions, etc.) corresponding device. In the field of textile industry, fabrics have been treated with organic antibacterial agents of quaternary ammonium salts very early, so that the fabrics have antibacterial properties. However, regardless of adding inorganic antibacterial agents or organic small molecule antibacterial agents, their common disadvantage is that the antibacterial agents will be separated from...
