Abstract
The invention discloses coating for a hub forming mold and a preparation method thereof. The preparation method of the coating comprises the steps that sodium alginate, sodium carboxymethyl cellulose, aluminum phosphate, soluble silicate, phenol formaldehyde resin and water are stirred and mixed, so that mixed liquor M is formed; after being subjected to still standing for 2-4 hours, the mixed liquor M is added with refractory powder and stirred, and then mixed liquor N is obtained; and the mixed liquor N is put in a sealed environment to be subjected to aging treatment, and the coating for the hub forming mold is obtained. The problems that the defects of pores, sand holes and the like of a casting occur due to the fact that the volatility of traditional coating is high, meanwhile, the strength of the traditional coating is low, and a formed coating layer is prone to being cracked are solved.
