Rapid detection method for curing degree of coating

The invention discloses a method for rapidly detecting the curing degree of a coating, which comprises the following steps: extracting field coating process parameters, providing a to-be-detected coating before curing, preparing a to-be-detected coating sample according to the proportion, preparing a plurality of test plates according to the field coating process parameters, curing in a room temperature environment, and detecting the curing degree of the coating at different curing times. Testing a plurality of groups of infrared spectrum data in situ, and calculating to obtain the curing degree of the coating according to the change condition of the relative peak area of the target peak and the internal standard peak; the hardness and the solvent resistance of the coating under different curing degrees are measured respectively, correlation analysis is carried out, the corresponding relation between the curing degree and the hardness and the solvent resistance is established, a coating curing degree judgment
