Casting mold material for ceramic forming, and ceramic forming mold

Abstract

The invention discloses a casting mold material for ceramic forming, and a ceramic forming mold. The casting mold material comprises, by weight, 100-140 parts of a vinyl ester resin, 80-120 parts of an epoxy resin, 80-120 parts of methyl methacrylate, 30-40 parts of triethyl phosphate, 20-30 parts of lanthanum oxide, 10-20 parts of cobalt powder, 10-20 parts of tungsten powder and 20-30 parts of talcum powder. Preparation of the ceramic forming mold by using the casting mold material comprises the steps of mixing the raw materials uniformly, and casting into the ceramic forming mold by a casting method according to the shape of a prefabricated ceramic product. The casting mold material takes a plurality of resins such as the vinyl ester resin, the epoxy resin and methyl methacrylate as a gel coat and triethyl phosphate as a plasticizer; and the resins are modified by lanthanum oxide, cobalt powder and tungsten powder, so that the prepared ceramic forming mold has good water-absorbing quality, light weight and very good performances such as heat resistance, wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of molds, in particular to a casting mold material for ceramic molding and a ceramic molding mold. Background technique [0002] Plaster molds are traditional molds that have been used for a long time in the production of oral ceramics and sanitary ware ceramics. Due to their low production cost and their own characteristics, they are still widely used in grouting, spinning, rolling, plastic pressing (cold pressing), etc. in the molding process. With the gradual development of the ceramic industry towards mechanized and automated production, the shortcomings of plaster molds have become more and more prominent, such as low strength and short service life. At the same time, the quality of the plaster mold directly affects and determines the quality of the molding body, and ultimately determines the quality of the product. Therefore, the limitations of the gypsum material itself have restricted the development of ...
