Abstract：The silica sol shell was obtained by using quick-drying silica sol as binder,and using 8 h and 20 h as the drying time of the back layer respectively.The drying degree of the shell was obtained by weight method,and the effect of drying time on the quality of the shell was studied.The results show that the water loss weight after 8 h drying have no significant change compared with that after 20 h drying,and the compact shell is obtained after 8 h drying and 20 h drying,with smooth surface and no peeling and crack.
