specific Embodiment approach 1

[0014] Specific implementation mode one: the preparation method of the color-coated dental arch wire for orthodontics in this embodiment is realized through the following steps: (1) pretreatment of the surface of the metal dental arch wire; (2) drawing the pretreated dental arch wire with a mold (3) Put the coated dental arch wire at a clean room temperature for 15 minutes, and cure it at high temperature to obtain a color-coated metal dental arch wire. Wherein step (2) described dip coating liquid is a kind of in water-based polyurethane emulsion and water-based acrylic emulsion, and brand is the white slurry of White-6 or the medium yellow slurry of Yellow-6 or the golden yellow slurry of Yellow-8 or Red-17 red paste or Black-6 black paste or Green-6 green paste or Bule-6 blue paste is mixed with one or more color pastes, and distilled water is added to make the dipping liquid The viscosity is Tu-4 cups, about 1 minute to 1 minute and 30 seconds.

specific Embodiment approach 2

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the metal arch wire in step (1) can be a NiTi alloy arch wire or a stainless steel arch wire. Other steps and selected parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the pretreatment in step (1) is ultrasonic cleaning in acetone, alcohol, and distilled water for more than 10 minutes to remove oil stains. Other steps and selected parameters are the same as those in Embodiment 1.

Abstract

A preparation method of an orthodontic color coating tooth arch wire is disclosed, and comprises the steps of: (1), performing surface pretreatment for a metal tooth arch wire; (2) straightening and fixing the pretreated metal tooth arch wire; and (3) standing the coated metal tooth arch wire at clean room temperature for 15min, curing for 10-30min at the curing temperature of 150-180 DEG C to obtain the color coating tooth arch wire. The preparation method provided by the invention is simple, and not affected by the shape of the tooth arch wire, causes no environmental pollution and can form a color coating (such as imitative golden, red, black, yellow, blue, green, pink and army green and the like) on the surface of the metal tooth arch wire so as to beautify the tooth arch wire. And the coating prevents the base metal from being directly contacted with oral saliva so as to effectively inhibit the base metal ions from releasing to human body and improve the using safety.

Description

technical field [0001] The invention relates to a method for preparing a coating, in particular to a method for preparing a colored coated dental arch wire for orthodontics. Background technique [0002] With the development of society, people pay more and more attention to their external details, and their requirements for beauty are getting higher and higher. People increasingly hope to have clean, white and healthy teeth when laughing and talking, so the orthodontic industry has developed rapidly in the past 10 years. The main metal orthopedic wires currently on the market are stainless steel wires and NiTi shape memory alloy wires. Due to the metal appearance of the metal dental arch wire itself, it is inevitable to bring a "metal smile" to the patient, which not only affects the appearance, but also affects the physical and mental health of young people. Therefore, we proposed in the invention patent application number 201110093878.0 to prepare a layer of colored coa...
