Coating special for waterborne thermalsetting PC of automotive interior and preparation method thereof

The invention discloses a coating special for waterborne thermalsetting PC of an automotive interior and a preparation method thereof. The coating is prepared from, by weight, 55-70% of waterborne polyurethane dispersoid, 4-10% of waterborne black paste, 5-15% of waterborne hydroxyl polyurethane dispersoid, 0.2-0.5% of defoaming agents, 3-5% of extinction powder, 1-2% of thickening agents, 1-2% of PH conditioning agents, 4-6% of diethylene glycol monobutyl ether, 0.2-0.5% of wetting agents, 0.2-0.5% of flatting agents and 4-10% of deionized water. According to the coating and the preparation method thereof, the raw materials are selected, the proportion of the raw materials in the formula is controlled, therefore, the prepared coating is good in fluidity and adhesive force, and a coated film has the high glossiness, the wear resistance, the alcohol resistance and the water boiling resistance.
