Abstract

The present invention discloses a high-plasticity wear-resistance ceramic material and a preparation method thereof. The preparation method comprises: weighing 3-9 parts of neodymium oxide, 5-12 parts of alumina, 20-38 parts of silica, 3-8 parts of zirconium oxide, 2-7 parts of boron oxide, and 1-6 parts of thorium oxide, and mixing in a ball mill to obtain a mixture A; adding the mixture A, 8-16 parts of cyclohexane dicarboxylic acid nonyl ester, and 23-35 parts of 2-methyl-2-nitro-1-propanol to a reactor, and carrying out a heating stirring reaction; continuously adding 12-18 parts of cellulose acetate phthalate and 15-25 parts of methyl 2-hydroxyethyl cellulose, and carrying out a stirring reaction at a temperature of 120-150 DEG C; drying in a vacuum oven to obtain mixed powder B; carrying out pressing molding on the mixed powder B under a pressure of 80-95 MPa; and placing into a muffle furnace under nitrogen protection, and calcining for 5-8 h at a temperature of 950-1000 DEG C so as to obtain the high-plasticity wear-resistance ceramic material. According to the present invention, the high-plasticity wear-resistance ceramic material has advantages of high melting point, high hardness, oxidation resistance and the like of the existing ceramic material, and further has good plasticity and good wear resistance.

Description

technical field [0001] The invention belongs to the field of ceramic materials, and relates to a high-plastic wear-resistant ceramic material and a preparation method thereof. Background technique [0002] Ceramic materials have the advantages of high melting point, high hardness, and oxidation resistance. It is a type of inorganic non-metallic material made of natural or synthetic compounds after forming and high-temperature sintering. It can be used as structural materials, tool materials, etc. Existing ceramics are mainly divided into two kinds of ceramic materials: ordinary materials and special materials. Ordinary materials are sintered from natural raw materials such as feldspar, clay, and quartz. They are typical silicate materials, and the main constituent elements are silicon, aluminum, and oxygen. Ordinary ceramics are rich in sources, low in cost, and mature in technology. Special materials refer to the use of high-purity artificially synthesized raw materials, w...
