Description
Technical field
The present invention relates to technical field of polymer materials, more particularly to a kind of PETG composites, its preparation method and should
With.
Background technology
Tooth is uneven also known as deformity of grinding one's teeth, refer to children in growth and development process, by inborn inherent cause or the day after tomorrow
Environmental factor, such as disease, oral habit, the deformity for tooth tooth, jawbone, cranium face caused by abnormal.
With the development of medical technology, many correction patients can be by wearing appliance come straightening of teeth.Appliance
It is a kind of device for treating malocclusion, orthodontic appliance can be claimed.Power can be acted, or the function of all flesh of masseter mouthful is made
Jawbone, malposed tooth and the Periodontal Supporting Tissue for firmly making deformity by appliance change, and are beneficial to jaw normal growth
Development.Known dental appliance has two kinds, and one kind is denture appliance, particularly by various metal parts for ring, annex
It is adhesively fixed on each tooth, by various arch wires, spring song, the bracket on fixing teeth is ligatured with ligature
On, the power straightening of teeth formed with ligature, this correcting technology has the disadvantages that：One is the time long, typically all in 2 years
More than, further consultation interval time is short, it is necessary to take patient's more time to complete correcting process；Two is to easily cause tooth trouble, fixed
Correction needs to install more apparatus for correcting intraoral, gives people the sensation of " embolum copper tooth ", the bad maintenance of oral hygiene, Ke Nengzao
Into gingivitis, tooth discoloration, tooth demineralization, canker sore etc..Put on the tooth of bracket or tooth silk, it is easy to block food residual
Slag, is also easy to be produced with mucous membrane of mouth friction the sensation for not accommodating pain, and influence attractive in appearance.Another kind is invisible orthotic device,
Correction patient carries out orthodontic by wearing without bracket stealth dental appliance.When just starting to wear appliance, appliance
Orthodontic force can be than more aggressive, but over time, due to appliance material, the screen resilience of appliance was at two weeks
It is interior progressively to disappear, specific visible Fig. 1.I.e. the Orthodontic force of appliance can fade away in two weeks, need more to renew after two weeks
Appliance increase Orthodontic force again.
In sum, there is provided a kind of dental appliance of long service life is the problem of our urgent need to resolve current.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to each reality of the invention
The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each implementation method of the invention,
In order that reader more fully understands the application and proposes many ins and outs.But, even if without these ins and outs and base
Many variations and modification in following implementation method, it is also possible to realize the application technical scheme required for protection.
First embodiment of the invention is related to a kind of preparation method of PETG composites, and the method includes following step
Suddenly：
(1) weighed in terms of weight/mass percentage composition：
PETG resins 80%；
Carbon nano-fiber 10%；
Auxiliary agent 10%；
Specifically, the auxiliary agent can be plasticizer, lubricant, antioxidant and bulking agent.
(2) PETG resins after dehumidifying drying 3 hours, are added into carbon nano-fiber, auxiliary agent at 65 DEG C, is mixed in high mixer
