Abstract

The invention relates to the technical field of aluminum profile processing, in particular to a method for preparing alkaline etching treatment liquid for aluminum profile alkaline etching treatment. The method comprises the following steps of firstly adding 5 parts of polyvinyl acetate emulsion, 5 parts of sodium carbonate and 20 parts of water into a container, and stirring for 5 minutes; then slowly adding 30 parts of sodium hydroxide and 10 parts of water while stirring, and stirring for 5 minutes after the completion of the adding operation; then slowly adding 0.5 parts of gastrodin and 5 parts of sorbitol while stirring, and stirring for 5 minutes after the completion of the adding operation; finally slowly adding 5 parts of sodium sulfide and 20 parts of water, and stirring for 20 minutes. The method for preparing the alkaline etching treatment liquid has the advantages that not only can the dissolving properties of all substances be improved, but also the possibility of particle agglomeration can be prevented by utilization of a gradual adding method and a reasonably-designed material adding sequence, therefore the surface protection function of the alkaline etching treatment liquid is significantly improved.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to a method for preparing an alkali etching treatment liquid for alkaline etching treatment of aluminum profiles. Background technique [0002] In the processing of aluminum profiles, alkali etching treatment is an indispensable treatment process and a key step to obtain a good surface for it. Due to the accumulation of sodium metasilicate, the traditional alkali etching treatment undergoes hydrolysis and precipitation, and the pollution to the environment is relatively serious. Contents of the invention [0003] In view of the technical problems existing in the prior art, the object of the present invention is to provide a method for preparing an alkaline etching treatment solution for alkaline etching of aluminum profiles. In order to achieve the above object, the present invention adopts the following technical solutions: [0004] A method for preparing an ...
