Method for preparing coating for hiding surface of orthodontic metallic tooth arc wire

Abstract

The invention provides a method for preparing a coating for hiding surface of an orthodontic metallic tooth arc wire, which comprises the following steps: (1) preprocessing the surface of the metallic tooth arc wire, ultrasonically cleaning the surface of the metallic tooth arc wire for 10 minutes in acetone, alcohol and distilled water, and removing oil stains; (2) straightening and fixing the preprocessed metallic tooth arc wire by using a mould, lifting and coating the metallic tooth arc wire in a dip-coating solution, wherein the dip-coating solution is stirred for 5-20 minutes at a stirring speed of 100-500 revolutions per minute and a lifting and coating speed is 0.5-5 millimeters per second; and (3) standing the coated metallic tooth arc wire for 15 minutes at room temperature, and then curing for 10-30 minutes at 150-180 DEG C, thereby acquiring a NiTi metallic tooth arc wire with a hidden coating. The method provided by the invention has the advantages that the preparation method is simple, the preparation method is free from being influenced by the shape of the tooth arc wire, the preparation method is environment-friendly, the coating is used for efficiently shielding the metallic color of the metallic tooth arc wire, and the coating has a function of hiding the tooth arc wire.

Description

technical field [0001] The invention relates to a method for preparing a coating, in particular to a method for preparing a stealth coating on the surface of a metal dental arch wire for orthodontics.
