The invention discloses an optical component completion protective coating, which is prepared from 10 to 20 parts of polyurethane emulsion, 50 to 60 parts of acrylic emulsion, 5 to 10 parts of ethyl cellulose, 0.1 to 0.3 part of a leveling agent, 0.1 to 0.3 parts of an antifoaming agent, 0.1 to 0.5 part of a dispersing agent, 5 to 10 parts of absolute ethanol and 10 to 20 parts of water. The protective coating for optical component processing prepared by the preparation method is harmless to a human body and the environment and has no fire hazard; during use, a film layer can be easily peeledoff, and the problems that an existing solvent type protective coating for optical component processing 'is harmful to the human body and environment, has the fire hazard and is inconvenient to use' due to an organic solvent are solved. 本发明公开了一种光学元件完工保护涂料，此涂料由10～20份聚氨酯乳液、50～60份丙烯酸乳液、5～10份乙基纤维素、0.1～0.3份流平剂、0.1～0.3份消泡剂、0.1～0.5份分散剂、5～10份无水乙醇、10～20份水制备而成。由本发明制备而成的光学元件加工用保护涂料对人体及环境无害、不存在火灾隐患、使用时可轻易剥离膜层，解决现有溶剂型光学元件加工用保护涂料因含有有机溶
