Bionic dental repair material and preparation method thereof

The invention discloses a bionic dental repair material and a preparation method thereof and belongs to the field of dental repair materials. The preparation method of the bionic dental repair material comprises the steps of, firstly, mixing and stirring magnesium nitrate, barium chloride, lithium carbonate, a polycarbonate and monoglyceride; secondly, mixing, at high speed, titanium dioxide, polyethylene oxide, hydroxy calcium phosphate, n-butyl polyvinyl ester and barium sulfate; thirdly, adding and uniformly mixing polyvinyl pyrrolidone, xanthan gum and carbomer; lastly, mixing and extruding the mixture above in a high-speed mixer to obtain the bionic dental repair material. The bionic dental repair material has the advantage that low-temperature mixing helps reduce the percentage of contraction and maintain stability of the bionic dental repair material; the added hydroxy calcium phosphate can enhance resin strength and enhance the service functionality of the bionic dental repairmaterial during dental re
