Abstract

The invention provides a phosphorus-free acidic cleaning agent, a preparation method and application thereof. The phosphorus-free acidic cleaning agent comprises the following components by weight: 60-70 parts of water; 15-20 parts of formic acid; 5-10 parts of an organic acid; 6-9 parts of an acidic buffer agent; 0.2-0.5 part of a corrosion inhibitor; 1-5 parts of a low-foam surfactant; and 1-5 parts of a builder. The invention further discloses a preparation method of the phosphorus-free acidic cleaning agent and application of the phosphorus-free acidic cleaning agent in the field of aluminum workpiece cleaning. The phosphorus-free acidic cleaning agent is scientific and reasonable in formula, and has the advantages of usability at normal temperature, low foam and workpiece appearance beautification while meeting the phosphorus-free requirement of the market.

Description

technical field [0001] The invention relates to cleaning agent technology, in particular to a phosphoric acid-free cleaning agent, its preparation method and application. Background technique [0002] Phosphoric acid has always been an important part of acid cleaning agents due to its unique properties, especially in the cleaning of various aluminum materials. However, as the phosphorus enrichment of water bodies has become more and more serious in recent years, people have become more and more cautious about the use of phosphorus. At the same time, countries around the world have also introduced different phosphorus emission restriction policies. Therefore, high-efficiency phosphorus-free products have become a type of product that is urgently needed in the market. On the other hand, under the poor prospect of the global economic situation, various enterprises have higher and higher demands for low-temperature cleaning and spray cleaning. However, even if the mainstream ...
