[0002] Non-metallic wear-resistant ceramic materials can be applied on metal surfaces as wear-resistant and heat-resistant layers. At present, "hydration bonding method" is commonly used to produce non-metallic wear-resistant ceramic materials , this method usually uses cement and water to mix at room temperature, and then mixes the mixture of cement and water with aggregate, micropowder, dispersant, and steel fibers in the wear-resistant ceramic material to produce a wear-resistant ceramic material with a certain strength. , the wear-resistant ceramic material produced by this method has high porosity, is not resistant to high temperature, and the compressive strength and refractoriness decrease. Due to the evaporation of water, a large number of pores appear on the surface of the ceramic material, which affects the appearance and reduces the density, wastes water resources, and increases production costs. , labor-intensive

Abstract

The invention relates to a flexible wear resistant ceramic material and its preparation method. Raw materials of the ceramic material provided by the invention comprise a wear resistant aggregate, a wear resistant fine powder, ceramic fibers and a binder. The preparation method provided by the invention comprises the following steps of: mixing sintered magnesia, quartz sand and corundum to prepare the wear resistant aggregate, mixing fine magnesia sand and quartz sand to prepare the wear resistant fine powder, mixing the wear resistant aggregate, the wear resistant fine powder and the ceramic fiber, adding the binder, and mixing again to prepare the wear resistant ceramic material. In the absence of water and in the presence of cement, bonding, polymerization or condensation of the wear resistant material, the ceramic material and the binder is successively carried out to form the flexible wear resistant ceramic material with high temperature resistance, wear resistant and high strength resistance. The preparation method is simple and convenient; the wear resistant ceramic material prepared has low porosity, beautiful appearance and high density; by the utilization of the wear resistant ceramic material, water resources are saved, the production cost is reduced and the consumption of labor force is minimized; the raw materials are low in price, are convenient to purchase, and have abundant sources.
