[0027] Specifically, the preparation method of the present invention includes:

[0028] First enter step S1100 to prepare wax emulsion: add a certain amount of emulsifier into water and mechanically stir vigorously, then add microcrystalline wax and paraffin wax and heat at 80-100°C for 20-60 minutes to make wax lotion. Then enter step S1200 nanocellulose surface lipophilic treatment: the nanocellulose is formulated into a nanocellulose aqueous solution with a concentration of 1-10% by mass, then mixed with the wax emulsion, dried at 105 ° C, and ground to obtain a surface hydrophilic Oily nanocellulose. The main purpose of this step is to coat a layer of wax on the surface of nanocellulose to improve its lipophilicity, thereby improving the dispersion uniformity of nanocellulose in polymethyl methacrylate, avoiding agglomeration, and further improving polymethacrylic acid. Mechanical strength of methyl esters. Preferably, this step further includes homogenizing the nanocel...

Abstract

A preparation method of an artificial tooth material is disclosed by the invention, and comprises: providing raw materials including polymethyl methacrylate and nano-crystalline cellulose. The preparation method of the material comprises the following steps: adding an emulsifier into water and stirring, then heating after adding microcrystalline wax and paraffin, to obtain a wax emulsion; preparing an aqueous solution of nano-crystalline cellulose with a concentration of 1-10%, mixing the aqueous solution with the wax emulsion, drying at a temperature of 105 DEG C, grinding, to obtain the nano-crystalline cellulose with a lipophilic surface; adding the surface-lipophilic nano-crystalline cellulose into polymethyl methacrylate, ball milling for 6-15 h. The artificial tooth material provided by the invention can help to effectively solve the problem of insufficient mechanical strength of a conventional artificial tooth, and can help to improve the artificial tooth strength and meet the requirement from doctors and patients to the artificial tooth.

Description

technical field [0001] The invention relates to a material, especially an artificial tooth material and a preparation method thereof. Background technique [0002] At present, the most clinically used artificial tooth material is polymethyl methacrylate, which has the advantages of convenient operation, corrosion resistance, strong resistance to fragmentation, strong designability, good biocompatibility, low cost, It is very popular among doctors and patients due to its strong and durable features. However, due to the poor mechanical properties of polymethyl methacrylate, the easy cracking of the artificial tooth base has not been well solved. [0003] Therefore, it is desirable to provide an artificial tooth material with better mechanical properties. Contents of the invention [0004] To this end, the present invention proposes a novel artificial tooth material and a preparation method thereof that can solve at least part of the above-mentioned problems. [0005] Acco...
