Abstract
The invention discloses a kind of novel mouth section glass ionomer/fluorinated graphene composite materials.The present invention is uniformly mixed the two using the method that mechanical ultrasonic is blended using conventional glass-ionomer cement pulvis common in clinical oral and fluorinated graphene as raw material.The two is dispersed in absolute ethyl alcohol by a certain percentage, ultrasound promotes its dispersion, and grinding is uniform and ethyl alcohol is made to volatilize completely, obtains novel dental material --- glass ionomer and fluorinated graphene mixing powder.Preparation method of the present invention is simple, equipment is simple, cheap, easy to promote large-scale.Novel dental material prepared by the present invention has high microhardness, high compression-strength, high-wearing feature, high anti-microbial property, with the color and luster for influencing material frequently, Fluoride release performance and dissolubility.The quality of filler can significantly be improved, expanded glass ionomer in clinical application range.
Description
Technical field
The invention belongs to medical high polymer technical fields, are related to a kind of novel mouth section glass ionomer/fluorination stone
Black alkene composite material.
Background technology
Glass ionomer is a kind of clinically used repair materials of department of stomatology.It is invented from last century the seventies
After coming, because it is with long-term fluorine releasability, good caking property and biocompatibility, smaller plup stimulus, with tooth
The near coefficient of thermal expansion of toe joint and translucent white colored appearance are widely used in restoration of tooth, fissure blockade, rebasing, glue
All various aspects of the clinical orals such as knot.But for a long time, since the mechanical strength of glass ionomer is low, brittleness is big, wear-resisting
Property is poor, the defects of to water sensitive, it is made to be difficult to bear the larger stress in backteeth area and long-term oral restoration.In Clinical practice, often
Dummy is caused to come off in short term, the generation of secondary caries seriously limits the further extensive use of glass ionomer.Institute
To improve its mechanical performance, it is the hot spot being modified to glass ionomer to enhance wearability and antibiotic property.Previous research is led to
It crosses and is changed to glass ionomer pulvis addition metal, hydroxyapatite, resin, glass fibre, inorganic nano-particle etc.
Property.However, the addition of metal can influence the color and luster of artificial tooth, the practicality is reduced；Resin compounded glass ionomer possess compared with
Good mechanical performance and antilysis, but the addition of resin can influence its Fluoride release, and polymerize caused by resin polymerization
The bonding of tissue can be influenced by shrinking；Its mechanical performance can be enhanced, but manufacture craft is more demanding by adding in glass fibre, be industrialized
Production is difficult；The addition of hydroxyapatite can effectively improve its biological property, but mechanical performance is not improved；Nano-particle
Filler mainly has nano-titanium dioxide, nano zirconium dioxide, nanometer fluor-apatite etc., these particles easily occur to reunite so as to make
The advantages of nano material, cannot show well.
Graphene has excellent heat conduction, conductive and mechanical properties, while has good biocompatibility, thermal stability
And chemical stability, in recent years by the concern of material circle.Fluorinated graphene not only retains as a kind of derivative of graphene
The good characteristic of graphene, such as mechanical performance, antibiotic property etc., and with its peculiar property.It is low with polarity, hydrophobic to dredge
The characteristics of oily, while fluorinated graphene is white, dispersion liquid is transparent, and does not influence the color and luster of material.
Invention content
The object of the present invention is to provide a kind of novel mouth section glass ionomer/fluorinated graphene composite materials.

1）Fluorinated graphene powder is added in the dispersion solution of the ultrasonic absolute ethyl alcohol for obtaining fluorinated graphene in absolute ethyl alcohol；
2）By glass ionomer pulvis add in fluorinated graphene absolute ethyl alcohol dispersion solution in, ultrasound obtain glass from
Sub- cement and fluorinated graphene dispersion solution, it grinds in mortar uniformly, after making ethyl alcohol volatilization complete, obtain glass from
Sub- cement and fluorinated graphene mixing powder；
3）Mixing powder and glass ionomer liquor tune are mixed, novel artificial tooth packing material is obtained after its curing.
The mass ratio of the mixing powder and glass ionomer liquor is 2：1.
Fluorinated graphene is added in conventional glass-ionomer cement pulvis by the present invention, has prepared novel dentistry
Filler makes its conventional glass-ionomer cement than current Clinical practice have more excellent mechanical strength, wear-resisting
Property, stronger antibiotic property, the Fluoride release ability of longer time, so as to delay the formation of secondary caries, and it is in beautiful color, face
Bed is highly practical.
