Casting die material for ceramic forming, and ceramic molding die

Abstract

The invention discloses a casting die material for ceramic forming, and a ceramic molding die. The casting die material is prepared from the following components in parts by weight: 80-160 parts of vinyl ester resin, 100-150 parts of 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 talc powder. A method for preparing the ceramic molding die by using the casting die material comprises the following steps: evenly mixing the raw materials, and castingthe obtained mixture into the ceramic molding die by using a casting method according to the shape of a prefabricated ceramic product. The casting die material is prepared by using multiple resins such as the vinyl ester resin, the epoxy resin and the methyl methacrylate as gel coat and taking the triethyl phosphate as a plasticizer, and the resins are modified by using the lanthanum oxide, the cobalt powder and the tungsten powder; the prepared ceramic molding die is good in water absorption and light in weight, and has very good heat resistance, wear resistance, corrosion resistance, and the like.

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] Gypsum mold is a traditional mold used for a long time in the industrial production of oral ceramics and sanitary ware ceramics. Due to its low production cost and its own characteristics, it is 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 gypsum molds have become more and more prominent, such as low strength and short service life. At the same time, the quality of the gypsum mold directly affects and determines the quality of the formed body, and ultimately determines the quality of the product. Therefore, the limitations of the gypsum material itself have restricted the development of the ceramic industry...
