Abstract

The invention discloses a zircon powder coating which is characterized by comprising the following components in percentage by weight: 52 percent to 58 percent of zircon powder; 1.2 percent to 1.7 percent of titanium dioxide, 1.2 percent to 1.7 percent of lithium-base bentonite, 1.2 percent to 1.7 percent of attapulgite, 0.51 percent to 0.6 percent of butyral resin, 0.68 percent to 0.88 percent of white dextrins, 0.51 percent to 0.6 percent of white latex, 32.5 percent to 35.6 percent of methanol and 4.2 percent to 5.22 percent of ethanol. The invention also discloses a preparation method of the zircon powder coating. The zircon powder coating and the preparation method thereof have the advantage that the zircon powder coating prepared from the components has the advantages of high strength, high adsorbing speed, strong adhesive force, good collapsibility and the like. A casting cast by the coating has the characteristics of smooth runner and smooth surface.

Description

technical field [0001] The invention relates to a zircon powder coating and a manufacturing method thereof; in particular to a zircon powder coating with the advantages of high strength, fast absorption, strong adhesion and good collapsibility, etc., which is prepared using zircon powder as a main raw material. The invention also relates to a method for preparing the coating. Background technique [0002] When the zircon powder coating currently on the market is used on castings or clay cores, due to its unreasonable formula, defects such as sintering, casting surface pores and rough appearance, and broken cores often occur. Makes the applicable product qualification rate low. Contents of the invention [0003] The main task of the present invention is to provide a zircon powder coating, specifically a zircon powder coating with high strength, fast absorption, strong adhesion and good collapsibility. [0004] In order to solve the above technical problems, a zircon powde...
