preparation example Construction

[0036] The invention provides a method for preparing a magnetic iron-based resin material, which is used for tooth restoration, especially for the preparation of dentures. The method comprises the following steps:

[0037] (1) reducing the ferrous sulfate reaction solution to obtain iron particles;

[0038] (2) in-situ oxidation of iron particles to obtain oxidized iron particles;

[0039] (3) using a modifier to modify the surface of the oxidized iron particles to obtain surface-modified iron particles;

[0040] (4) Coating the surface-modified iron particles with resin to obtain a magnetic iron-based resin material.

[0041] The ferromagnetic iron-based resin material provided by the present invention contains iron particles capable of magnetically adsorbing with magnets or permanent magnets, and the iron particles are used as cores, and are gradually modified and wrapped to obtain a ferromagnetic iron-based resin material.

[0042] There are many ways to obtain iron parti...

Abstract

The invention provides a magnetic iron-based resin material, and a preparation method and application thereof. According to the preparation method of the magnetic iron-based resin material, in-situ oxidation is carried out on iron particles obtained by reducing ferrous sulfate; surface modification is carried out by a modifier; and then coating is carried out by resin, so that the magnetic iron-based resin material is obtained. The magnetic iron-based resin material comprises a plurality of iron-based magnetic particles, and each particle sequentially comprises an iron core, an oxidation film,a modification film and a resin film from inside to outside, so that the magnetic iron-based resin material has strong and lasting magnetism, and can be used for tooth repair, particularly denture installation.

Description

technical field [0001] The invention relates to a strong magnetic iron-based resin composite material, in particular to a strong magnetic iron-based resin material for tooth restoration and a preparation method thereof, belonging to the field of new materials. Background technique [0002] In modern society, people pay more and more attention to dental health, and often choose to install dentures after serious dental problems. Dentures are generally divided into removable dentures, fixed dentures and implant dentures. Dental implants are first implanted into the alveolar bone of the missing teeth, and after a period of time, fixed or removable dentures are repaired on the upper part of the implants. In addition to having fixed dentures, implant dentures do not need to grind away the natural tooth tissue adjacent to the gap, which expands the indications for fixed dentures. However, artificial tooth roots implanted in the alveolar bone will cause certain damage to the alveo...
