Light scent type surface treating agent for aluminum alloy

Abstract

The invention discloses light scent type surface treating agent for aluminum alloy. The light scent type surface treating agent comprises the following raw materials in parts by weight: 0.6-1 part of benzoic acid, 0.3-1 part of cobalt aluminate, 2-3 parts of alkyl succinic acid, 2.2-4 parts of potassium dichromate, 0.2-0.5 part of citronellol, 1-2.6 parts of maleic anhydride, 2-3 parts of glycerinum, 0.1-0.2 part of pine tar, 0.3-1 part of tetrabutylammonium bromide, 1-2 parts of palm wax, 0.1-0.2 part of hydrotalcite powder, 0.1-0.3 part of chromium carbide, 2-4 parts of coalescing agent, 16-20 parts of 3-amido propyl trimethoxy silane, and110-130 parts of de-ionized water. The surface treating agent has the advantages of good environmental protecting performance, less treated sediment and light scent, can improve the antibacterial and antiseptic property, and can enhance the workpiece protecting effect.

Description

[0001] technical field [0002] The invention mainly relates to the field of surface treatment, in particular to a light fragrance aluminum alloy surface treatment agent. Background technique [0003] There are many surface treatment methods for aluminum alloys, such as physical methods, chemical methods, physicochemical methods, and comprehensive methods. The commonly used method is the anodic oxidation method, which forms a conversion film on the surface of the aluminum alloy by an electrochemical method. Although this method can improve the light fragrance performance of the aluminum alloy, its ability to adapt to the environment is poor, and the conversion film layer is not uniform enough. The wear resistance has not been improved, and the traditional phosphate conversion and chromate passivation surface treatment technology can obtain good results, but the waste liquid discharged during the treatment process contains zinc, manganese, nickel, chromium and other heavy m...

The commonly used method is the anodic oxidation method, which forms a conversion film on the surface of the aluminum alloy by an electrochemical method. Although this method can improve the light fragrance performance of the aluminum alloy, its ability to adapt to the environment is poor, and the conversion film layer is not uniform enough. The wear resistance has not been improved, and the traditional phosphate conversion and chromate passivation surface treatment technology can obtain good results, but the waste liquid discharged during the treatment process contains zinc, manganese, nickel, chromium and other heavy metals Carcinogens such as ions and sub-light scents are very serious to environmental pollution, and the metal surface silanization treatment technology is considered to be expected to replace phosphate conversion treatment because it does not involve substances that are harmful to the environment, the production process has low energy consumption, and the technology has a wide range of applications. And chromate passivation treatment is the latest development direction of metal surface protection alone
