A kind of environment-friendly quick-drying raw lacquer coating and preparation method thereof

Abstract

The invention relates to the field of natural polymers, in particular to an environment-friendly quick-drying raw lacquer coating and a preparation method thereof. The preparation method comprises the following steps: mixing the original raw lacquer emulsion and a moisturizing agent, and stirring at a temperature of 20-30°C for 10min-30min to obtain Raw lacquer paint; wherein, the mass fraction of the humectant is 1%-10%. The moisturizing agent is one or more of xylitol, ethylene glycol, glycerol, butylene glycol, triethylene glycol, hyaluronic acid and chitin. The present invention adds humectant to the original raw lacquer emulsion, the drying and curing time is greatly shortened, the hard drying time after painting can be shortened from the original 52 hours to 15 hours, and the drying time can be shortened by 71%. At the same time, the hardness of the paint film after rapid drying is good.

Description

technical field [0001] The invention relates to the field of natural polymers, in particular to an environment-friendly quick-drying raw lacquer coating and a preparation method thereof. Background technique [0002] Raw lacquer, commonly known as "earth lacquer", also known as "national lacquer" or "big lacquer", is a milky white pure natural liquid paint harvested from lacquer trees. King". [0003] The economic value of raw lacquer is very high. It has the advantages of high hardness, good wear resistance, good gloss, and high compactness of the paint film. It is a high-quality coating for military industry, industrial equipment, agricultural machinery, basic construction, handicrafts, and high-end furniture. However, raw lacquer has disadvantages such as poor weather resistance and poor adhesion to metals. In practical applications, raw lacquer must be dried in a specific humid and hot (relative humidity 70%-90%, temperature 25-35°C) environment. Drying conditions and ...
