Abstract:Abstracts:In order to study the performance of black high light raw lacquer coating, natural raw lacquer from five places of origin was selected as research object and mixed with black material according to different mixing ratios and modulated. Taking the proportion, drying temperature and humidity as the variables, We determined the physical and mechanical properties of the drying time heat resistance and chemical corrosion resistance . Through orthogonal optimization and multi-factor analysis of variance, the influence of various factors was humidity≥temperature≥content≥blend proportion.The best formula was 1 Kg of 71% raw lacquer plus 50% black material and 2.02 assistant. The results of the experiments showed that the shortest drying time was 22.6 hours when the temperature was 25℃ and the humidity was 85%. Compared with refined Chinese lacquer, the black high lacquer coating possessed superior performance.
