Abstract

A surface treating agent for copper and copper alloys comprises the components in parts by mass as follows: 100 parts of sodium hydroxide, 0.2-0.5 part of a pickling inhibitor, 1-3 parts of ethanol, 15-35 parts of sodium phosphate, 8-10 parts of an emulsifier, 10-40 parts of sodium carbonate, 1-5 parts of a butyl cellosolve, 5-10 parts of a surfactant, 4-5 parts of triethanolamine, 10-15 parts of sodium tripolyphosphate, 5-10 parts of sodium hexametaphosphate, 20-25 parts of turpentine and 10-20 parts of water. The surface treating agent is good in oil stain removing performance and high in derusting capacity, takes 1-4 h for treatment at the room temperature and 5-15 min for treatment at the temperature of 60-80 DEG C, can be widely produced and can continuously replace existing materials.

Description

[0001] technical field [0002] The application belongs to the field of metal surface treatment agents, in particular to a copper and copper alloy surface treatment agent. [0003] Background technique [0004] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. big impact. [0005] The alkaline cleaning agents mainly include sodium hydroxide, sodium carbonate, sodium silicate, sodium phosphate, etc., which dissolve in water to become alkaline cleaning agents. The principle of their action is that they can saponify with the fatty acid glycerides in the oil to form nascent soap, making the oil water-soluble and ...
