Abstract

The invention discloses a ceramic die material with good high-temperature hardness and a preparation method thereof. The ceramic die material is prepared from, by weight, 3-8 parts of molybdenum powder, 48-56 parts of epoxy resin, 3-10 parts of surfactant, 1-5 parts of curing agent, 9-15 parts of binder, 25-34 parts of glass fibers, 15-22 parts of graphite powder, 3-8 parts of boron powder and 40-50 parts of quartz powder. All the raw materials are mixed to be uniform, and the raw materials are hot-rolled into a blank after being subjected to vacuum arc remelting smelting; the blank is heated to 850-950 DEG C, heat is preserved for 1-2 h, then the temperature is raised to 1,050-1,100 DEG C within 1-2 h, heat is preserved for 8-10 h at the temperature, and then the blank is oil-cooled to room temperature; and the ceramic die material is obtained after first heating number aging treatment and second heating number aging treatment. The ceramic die material has the beneficial effects of being good in high-temperature performance, high in strength, abrasion resistance and toughness and the like, and the manufacturing cost is low; and when the ceramic die material is used for a hot extrusion die of non-ferrous metals, the service life of the die is greatly prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic molds, in particular to a ceramic mold material with good high-temperature hardness and a preparation method thereof. Background technique [0002] In the casting process, the mold is an essential casting process equipment, and the technical level of the mold manufacturing directly affects the quality of the casting. Ceramic molds have always played a major role in the overall composition of abrasive tools. Although with the continuous development of binder materials and the improvement of mold types, the output of ceramic molds has shown a downward trend in the total output of molds, but it is still in the total mold. occupy a large proportion. The advantages of ceramic molds: high strength, high hardness, moisture-proof, wear-resistant, stain-resistant, corrosion-resistant, high-temperature resistant, easy to clean, small deformation, good insulation, and has certain resistance to rapid cooling...
