Abstract

The invention discloses a PEEK false tooth composite. The PEEK false tooth composite is prepared from, by weight, 110-150 parts of polyether-ether-ketone, 10-20 parts of nano calcium silicate, 8-12 parts of hydroxyl hydroxyapatites, 4-8 parts of barium glass short fibers, 15-22 parts of organic solvent, 8-18 parts of refined paraffin, 1-4 parts of co-binding agent, 8-12 parts of binder, 2-6 parts of antibacterial agent, 6-10 parts of carbide and / or 8-15 parts of oxide. The invention further discloses a preparation method of the PEEK false tooth composite. The preparation method includes the steps that firstly, the raw materials of nano calcium silicate, hydroxyl hydroxyapatites, carbide and / or oxide are mixed, the mixture is heated to 150-220 DEG C, the situation is kept for 10-30 min, cooling is carried out, the refined paraffin is added, mixing and stirring are carried out, and after the mixture is crushed ultrasonically, the organic solvent, polyether-ether-ketone, the co-binding agent, the binder and the antibacterial agent are added to be stirred till uniform paste is obtained; finally the barium glass short fibers are added, ball-milling and drying are carried out, and the finished composite powder is obtained.

Description

technical field [0001] The invention relates to composite dental implant material technology, in particular to a PEEK denture tooth composite material and a preparation method thereof. Background technique [0002] Polyether ether ketone, the English name is: polyetheretherketone (referred to as PEEK), it is a linear aromatic polymer compound containing chain links in the main molecular chain. Its constituent units are oxygen-p-phenylene-oxygen-carbonyl-p-phenylene, which is semi-crystalline and thermoplastic. It has good physical and mechanical properties, high temperature resistance, corrosion resistance and good creep resistance and anti-corrosion properties. Fatigue performance, and chemical stability is also very good, except for concentrated sulfuric acid, it is very stable to almost any chemical reagents, even at higher temperatures, it can still maintain good chemical stability, in addition, it also has excellent Hot water resistance and steam resistance, can be use...
