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
The present invention relates to a kind of preparation method of coating, relate in particular to a kind of just abnormal preparation method with the coloured coating dental arch filament.
Background technology
Along with the development of society, People more and more is paid attention to the outside details of oneself, to U.S.A require increasingly high.People more and more hopes oneself to have the neat pure white and healthy tooth of a bite when laughing heartily, associating talk, and therefore just abnormal industry developed very swift and violent in nearly 10 years.The main in the market metal orthopedic wire that uses has stainless steel wire and NiTi shape-memory alloy wire.Because the metal appearance of metal dental arch filament itself inevitably brings " metal smile " to the patient, not only influence attractive in appearancely, also influence teen-age physical and mental health.Therefore, we number are to propose preparation one deck has the tooth true qualities on the metal dental arch filament coloured coating in 201110093878.0 to eliminate " metal smile " in application for a patent for invention.The main service object of orthodontic treatment is the teenager, and has the teenager of most to pay attention to very much making widely known of self-individual character, and anything is pursuing individualityization all.Machine-made metallochrome and tooth true qualities be difficult to satisfy they fashion, follow the fashion the requirement of outstanding individual character.For this reason, the colored dental arch filament that highlights individual character has also just had a large amount of market.At present; Existing scholar adopts the surface oxidation treatment method to form coloured coating at stainless steel dental arch filament and bracket, and the method is to be immersed in stainless steel-based surface through the control current potential in the chromium sulfate aqueous acid to form the oxide-film generation it is thus clear that interference of light forms various coloured coatings.
Summary of the invention
The object of the present invention is to provide a kind of just abnormal preparation method with the coloured coating dental arch filament; The thicknesses of layers that this method forms is thinner; Rete is that metal oxide possibly come off under the stress effect easily, and has a large amount of chromium with genotoxic potential in the oxidation film layer.It is matrix that the present invention adopts the polyurethane of good biocompatibility and acrylic acid, adds various avirulent inorganic or organic mill bases, uses to lift dip coating at the various coloured coatings of metal dental arch filament surface formation, and the preparation method is simple, is easy to industrialization production.For satisfying the just abnormal patient's fashion of teenager, following the fashion the requirement of outstanding individual character.
The present invention realizes that like this method step is:
Method step is:
(1) just abnormal with the surface preparation of metal dental arch filament, in acetone, alcohol, distilled water, respectively carry out ultrasonic cleaning and handle more than the 10min, remove oil stain;
