wherein the mass fraction of the humectant is 1-10%.
The invention has the beneficial effects that: according to the invention, after the humectant is added into the original raw lacquer emulsion, the raw lacquer is dried to form a film at different temperatures and humidities, compared with pure raw lacquer, the modified quick-drying raw lacquer has enough moisture due to the existence of the humectant in the modified quick-drying raw lacquer even under a low-humidity environment (such as RH 60%), and the drying process can maintain the activity of laccase, so that the drying and film-forming time of the modified raw lacquer is not influenced or even shortened. The actual drying time after painting can be shortened from 52 hours to 15 hours, and the drying time can be shortened by 71 percent. Under different environment conditions for drying raw lacquer, the drying and curing time of a lacquer film is shortened, and the hardness of the lacquer film is good. The raw lacquer is natural lacquer, and the raw lacquer coating is prepared by only adding the humectant to mix and disperse, so that the raw lacquer is convenient to operate, green and environment-friendly, and has good application prospect and use value.
