Sea-buckthron-oil-containing aluminum alloy surface treatment agent

Abstract

The invention discloses a sea-buckthron-oil-containing aluminum alloy surface treatment agent, which comprises the following raw materials in parts by weight: 0.1-0.3 part of trichloroisocyanuric acid (TCCA), 1-2 parts of ammonium zirconium hexafluoride, 0.3-0.5 part of glyceryl monostearate, 0.2-0.3 part of an antioxidant 1010, 0.1-0.5 part of sea buckthorn oil, 1-2 parts of hexamethylphosphoric triamide, 2-3 parts of ammonia chloride, 1-2 parts of extylene diamine tetra (mextylene phosphonic acid) sodium, 2-3 parts of sorbic alcohol, 0.2-0.4 part of molybdenum boride, 3-4 parts of a film forming aid, 12-19 parts of 3-aminopropyl trimethoxysilane and 100-130 parts of deionized water. According to the sea-buckthron-oil-containing aluminum alloy surface treatment agent, the raw materials are safe and good in environmental protection, the traditional harmful constituents such as nitrate are nonexistent, damage to human bodies and the environment is avoided, the treatment method is simple, and the formed coating is even and level and high in adhesion strength.

Description

[0001] technical field [0002] The invention mainly relates to the field of surface treatment, in particular to an aluminum alloy surface treatment agent containing seabuckthorn oil. 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 performance of the aluminum alloy containing seabuckthorn oil, its ability to adapt to the environment is poor, and the conversion film layer is not uniform enough. It is easy to fall off, and the wear resistance has not been improved. Although the traditional phosphate conversion and chromate passivation surface treatment technology can obtain good results, the waste liquid discharged during the treatment process contai...
