| titleOfInvention | High-temperature-resistant coating for resin sand casting and preparation method thereof |
| abstract | The invention discloses a high-temperature-resistant coating for resin sand casting and a preparation method thereof, relating to the technical field of casting coatings, and the technical scheme is that the high-temperature-resistant coating for resin sand casting comprises the following components: refractory aggregate, binder, suspending agent, defoaming agent and water; the refractory aggregate is prepared by mixing modified kaolinite powder, calcined kaolinite powder, zircon powder and boron carbide powder in a weight ratio of modified 5:3:1: 1; the suspending agent is prepared by mixing 3:1:1 by weight of lithium bentonite, microcrystalline cellulose and sodium polyacrylate; the binder is prepared by mixing yellow dextrin and polyvinyl butyral according to a weight ratio of 4: 1. The coating with good suspension property and stable quality is obtained by matching the modified kaolin powder, the calcined kaolin, the zircon powder, the boron carbide, the suspending agent, the binder and the defoaming agent; when the adhesive is coated on the side wall of the sand mold, the adhesive can be uniformly attached to the side wall of the sand mold and has good high-temperature bonding strength. |
