30 parts of glue, 30 parts of PVPP, SiO212 parts, 2 parts of sodium monofluorophosphate, ultraviolet absorbent UV-531 be 1
Part, 0.05 part of nano zircite, 2 parts of sodium alginate, 8 parts of nacre powder.
The preparation method of above-mentioned dental adhesive is：（1）Each raw material is weighed by weight, epoxy resin, crosslinking is poly-
Vinylpyrrolidone is added in reactor, is heated to 60 DEG C, stirs 5min, and mixing speed is 120r/min；（2）Continue to heat up
To 80 DEG C, sodium alginate, peach gum, Arabic gum are added, continue to stir, cooled down after reaction 120min；（3）By SiO2, nano oxygen
Change zirconium, the addition of nacre powder and obtain step（2）In obtained reaction solution, 30min is stirred；（4）Continuously add sodium monofluorophosphate, purple
Ultraviolet absorbers UV-531, stirs 10min, obtains final product dental adhesive.
The property indices of material of the present invention see the table below, it may be seen that this dental adhesive has drawing very high
Shear strength is stretched, 33.02MPa is reached as high as, while in addition inorganic filler zirconium silicate, titanium carbide, improve the hard of adhesive
Degree, reaches 31.25MPa, illustrates the volume that the increase of inorganic filler is effectively reduced in resin monomer solidification process to a certain extent
Shrink, and can reduce material catch a cold thermal change when stereomutation.
The property indices of the dental adhesive of table 1
