DOS oil coating method

The invention discloses a DOS oil coating method. The DOS oil coating method comprises the following steps of: cleaning, removing a trace amount of a degreasing agent, washing away a light-emitting agent, drying, carrying out chromizing treatment, drying, coating a coating, curing the coating, slitting, printing, coating the coating, curing the coating, S14 waxing and the like. According to the DOS oil coating method, roll coating and sheet coating are combined, the advantage of relatively high roll coating efficiency is utilized, outer coating in two times of coating (outer coating and innercoating) carried out on a sheet coating line is changed into outer coating carried out on a roll coating line, and the work which needs more than ten minutes on the sheet coating line can be finishedin a few seconds, so that the printing and coating efficiency can be greatly improved. 本发明公开了一种DOS油涂覆方法，包括清洗、去除微量脱脂剂、洗掉出光剂、烘干、铬化处理、烘干、涂覆涂料、固化涂料、分切、印刷和涂覆涂料、固化涂料、S14涂蜡等工序，由于本发明将卷涂和片涂相结合，利用卷涂效率较高的优点，将原本在片涂线进行的两遍涂布（外涂和内涂）中的外涂改为在卷涂
