Abstract
The invention discloses a ceramic glaze composite material for an electric water heater and application thereof. The coating is mixed from two ceramic glazes with different properties and water according to a certain weight ratio, and comprises 30-50 parts of component A, 50-70 parts of component B and 30-40 parts of water, wherein SiO2 content is greater than 50%. The coating has good flow property and uniform thickness, and is suitable for mechanical automation flow to coat steel liner. The coated liner needs to be burnt at 835-855 DEG C high temperature furnace after drying, so that the coating forms a multicomponent low eutectic; coating on the burnt liner forms microcrystalline structure and fine bubble structure in the homogeneous cooling process; and the cooled coating and steel plate form a firmly combined composite coating. The coating has advantages of high temperature impact resistance, pressure impact resistance, hardly falling, corrosion resistance, smooth, hard and hardly scaled surface, environment-friendliness, sanitation and long service life, and is an ideal material for a novel water heater liner.
