Abstract

The invention relates to the technical field of machining of aluminum products, in particular to a preparing method of acid etching treating fluid for acid etching treating of an aluminum alloy part. The method comprises the steps: firstly adding 5 parts of sodium lauryl polyoxyethylene ether sulfate and 20 parts of water into a container, and stirring for 5 minutes; then slowly adding 5 parts of nitric acid while stirring, and stirring for 5min after adding; then slowly adding 50 parts of phosphoric acid and 10 parts of water while stirring and stirring for 5min after adding; then slowly adding 0.5 part of crotonoside and 0.5 part of carbonate diamine while stirring and stirring for 5min after adding; finally, slowly adding 5 parts of aluminum and 30 parts of water and stirring for 15min. According to the preparing method of the acid etching treating fluid, by the method of adding step by step and reasonably designing an adding sequence, a dissolving property among all substances is improved, possibility of particle aggregation is avoided, and a surface protection function of the acid etching treating fluid is obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of aluminum product processing, in particular to a preparation method of an acid etching treatment liquid for acid etching treatment of aluminum alloy parts.
