一种高悬浮低浓度的新型涂料及其涂覆方法和应用
摘要：
本发明公开了一种高悬浮低浓度的新型涂料，包括锆英粉涂料、纳米粉、呋喃树脂和光亮碳，各组分占锆英粉涂料的质量百分比如下：纳米粉1.5%~3%，呋喃树脂0.5%~1.5%，光亮碳2%~4%，本发明还公开了一种高悬浮低浓度的新型涂料的涂覆方法及该新型涂料在铸件树脂砂模具涂敷领域中的应用。本发明新型涂料悬浮性高，大大提高了涂料24小时悬浮率，涂料的粘附性和流平性好，减少了铸件表面流痕和刷痕，提高了铸件表面的光洁度，光洁度达到8级以上；本发明所述的涂覆工艺可有效减少涂料的使用量，降低成本，同时简化了操作工序由原来的淋涂、刷涂和清洗，现在只需淋涂以及清洗，铸件涂层均匀且耐久性好，铸件表面涂覆效果优异。
摘要（英）：

The invention discloses a novel coating material with high suspension and low concentration. The novel coating material comprises a zircon powder coating material, 1.5%-3% of nanometer powder based on the weight of the zircon powder coating material, 0.5%-1.5% of a furan resin based on the weight of the zircon powder coating material, and 2%-4% of lustrous carbon based on the weight of the zircon powder coating material. The invention also discloses a coating method for the novel coating material, and applications of the novel coating material in the fields of coating castings, resins and sand moulds. The novel coating material has advantages of high suspension property, improved 24-hour suspending percentage, good adhesion and flow leveling properties, reduced flow marks and brush marks on casting surfaces and improved surface finish of castings. The grade of the surface finish is higher than 8. The coating method has advantages of effectively reduced using amount of the coating material, reduced cost, uniform and durable casting coating and good casting surface coating effects. Operation process is simplified from original shower coating, brush coating and cleaning to only shower coating and cleaning.
