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
The present invention relates to a kind of preparation method of coating, relate in particular to a kind of just abnormal preparation method with metal dental arch filament surface camouflage coating.
Background technology
Along with the development of society, people more and more pay attention to the outside details of oneself, and are more and more higher to the requirement of U.S..People more and more wish 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 whole world has and surpasses eighty per cant people because bad life and eating habit and need carry out orthodontic according to incompletely statistics, need among the just abnormal crowd at these, developed country implements the suitable height of number ratio of orthodontic treatment, exaggeration say that orthopedic wire all is an essential product in U.S. army's nuclear submarine.The number that developing country implements treatment accounts for and needs more than 15% of number, and along with the raising of people's living standard, the number of receiving treatment will increase rapidly.And backward country's treatment is fewer in number.The annual wire for correcting shape of tooth that consumes in the conservative estimation whole world has 5 to 1,000,000,000 approximately.And the Chinese market demand has the just abnormal calculating of 1 people by per 200 people, annual consumption more than 50,000,000.And market growth is rapidly, along with the enhancing of Chinese national power, and the be well off raising of degree of people, China will become the country of orthopedic wire consumption maximum after 10 ~ 20 years.
The main in the market metal orthopedic wire that uses has stainless steel wire and NiTi silk.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, the camouflage coating that preparation one deck has tooth true qualities on the metal dental arch filament is very important.External existing relevant patent and product, and the domestic blank that almost still is in.People such as Wittman propose and can comprise polytetrafluoroethylene (PTFE), perfluoroethylene-propylene, CTFE, vinylidene fluoride, polyphenylene oxide resin etc. as the coating material of dental arch filament.It is comparatively suitable as the material of coating that people such as Chasanoff mention with 45% pair of equal polyester of formyl hydroxy base and the mixing of 55% polytetrafluoroethylene (PTFE); and attempt using acrylic resin, pure polytetrafluoroethylene (PTFE) as coating material; but find that coating abrasion performance is poor, intensity is low, and fragility is big.People such as Banerjee propose in order to improve coating adhesion to introduce the silane rete between coating and matrix.People such as Feng Xue adopt epoxy resin and water-based ptfe emulsion to be base, and titanium dioxide and iron oxide yellow are that pigment has prepared camouflage coating on the NiTi dental arch filament, but its lotion configuration is loaded down with trivial details, needs to add levelling agent, defoamer, dispersant and coupling agent etc.
Summary of the invention
The object of the present invention is to provide a kind of just abnormal preparation method with metal dental arch filament surface camouflage coating, for the metal appearance that solves metal dental arch filament itself brings " metal smile " to the patient, not only influence attractive in appearancely, also influence the able-bodied problem of teenager.
The present invention is achieved like this, and method step is:
(1) metal dental arch filament surface preparation is carried out ultrasonic cleaning and is handled more than the 10min in acetone, alcohol, distilled water, remove oil stain;
