Preparation method of scale material

The invention relates to a preparation method of a scale material. The method comprises the following steps of continuously arranging glass fiber or basalt fiber into one row; performing heat treatment at 850 to 1150 DEG C for 5 to 20 min; then, performing annealing for 1 to 5 h at 500 to 800 DEG C to obtain the scale material. The method has the advantages that the process is simple; the preparedscale has high flatness degree and can be filled into a coating at the maximum layers; in addition, a plurality of grooves are formed in fiber connecting parts of each scale, so that the surface friction between the scales and the resin is greatly improved; the performance of anti-corrosion coating can be effectively improved. 本发明涉及种鳞片材料的制备方法，包括：将玻璃纤维或玄武岩纤维连续排列成排，在850～1150℃下热处理5～20min，然后在500～800℃下退火1～5h，得到鳞片材料。本发明工艺简单，制备的鳞片平整度高，能最大层数的填充在涂层中，而且每个鳞片由于纤维连接处还有很多凹槽，大大增加了鳞片与树脂的表面摩擦力，能有效提高防腐涂料的性能。
