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 recoverymaterials 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] Antibacterial 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 agent or inorganic antibacterial agent to the polymer material. Nowadays, inorganic antibacterial agents, such as zeolite materials containing metal ions (silver ions, copper ions, zinc ions, etc.), are directly added to the polymer matrix, and mixed uniformly, together with the polymer matrix, directly prepared The corresponding device. In the textile industry, quaternary ammonium salt organic antibacterial agents have been used to treat fabrics to make the fabrics antibacterial properties. However, whether it is adding inorganic antibacterial agents or organic small molecule antibacterial agents, their common disadvantage i...
