Abstract

The invention discloses a long-acting antibacterial material, a dental diaphragm and a long-acting invisible appliance. The long-acting antibacterial material comprises PETG (polyethylene terephthalate glycol) resin and modified tourmaline, wherein the mass ratio of the PETG resin to the modified tourmaline is (10-50):1. The preparation method of the modified tourmaline comprises the following steps: S1, treating nano tourmaline with concentrated sulfuric acid to obtain porous nano tourmaline; S2, treating the porous nano tourmaline with glycerin to obtain hydroxylated porous nano tourmaline; and S3, grafting the hydroxylated porous nano tourmaline with limonin to obtain the modified tourmaline. According to the antibacterial material and the preparation method thereof, the PETG resin and the modified tourmaline are combined to prepare the antibacterial material which is safe and non-toxic, has a strong antibacterial effect and can resist bacteria for a long time, and the antibacterial material is also applied to dental diaphragms and invisible orthodontic appliances.

Description

technical field [0001] The invention relates to the field of antibacterial materials, in particular to a long-acting antibacterial material, a dental membrane and a long-acting invisible appliance. Background technique [0002] With the gradual improvement of people's quality of life, consumption concept and aesthetic awareness, consumers pay more and more attention to the visual aesthetics of tooth arrangement and the aesthetic feeling of health, comfort and stability of articulation function. The development of invisible aligners has greatly improved the wearing Aesthetics make it more comfortable and convenient to wear, combined with digital 3D technology to make the orthodontic effect intuitive and predictable. At the same time, with the changes in the socio-economic structure, invisible aligners without brackets gradually penetrate into the orthodontic market and become a trend in the orthodontic industry. [0003] The carrier of the invisible aligner is the aligner dia...
