Reflective insulation type automobile topcoat and preparation method thereof

The invention relates to the technical field of industrial coating, in particular to a reflective insulation type automobile topcoat and a preparation method thereof. The reflective insulation type automobile topcoat is prepared from, by mass, 50%-65% of waterborne acrylic resin, 0.5%-1.5% of pH conditioning agent, 6%-10% of cosolvent, 0.3%-1% of antifoaming agent, 0.5%-2.5% of infrared reflectioncomponents, 15%-20% of two-component amino resin, 0.3%-0.6% of flatting agent and 5%-20% of deionized water. The prepared automobile topcoat by adopting the method has the advantages of being high intransparency, good in glossiness, better in heat-insulating performance, high in rigidity and superior in weather fastness and chemical resistance performance, and the preparation method is simple inoperation and is applicable to mass production operation. 本发明涉及工业涂料技术领域，具体公开种反射隔热型汽车罩面漆及其制备方法。所述汽车罩面漆包含如下质量百分比的组分：水性丙烯酸树脂50％-65％，pH调节剂0.5％-1.5％，助溶剂6％-10％，消泡剂0.3％-1％，红外反射组分0.5％-2.5％，双组份氨基树脂15％-20％，流平剂0.3％-0.6％，去离子水5％-20％。本发明所制备
