6-series aluminum medium-temperature ultrasonic cleaning agent and preparation method thereof

Abstract

The 6-series aluminum medium-temperature ultrasonic cleaning agent is prepared from the following components in percentage by weight: 72.3 percent to 86 percent of water, 1.8 percent to 3.5 percent of sodium metasilicate, 1.6 percent to 3.7 percent of triethanolamine, 0.5 percent to 1.3 percent of cocoanut fatty acid diethanolamide, 1.4 percent to 2.6 percent of isomeric fatty alcohol polyoxyethylene ether, 4.8 percent to 7.2 percent of OP-10, 0.9 percent to 1.4 percent of a penetrating agent and 3 percent to 8 percent of a cosolvent. The invention further discloses a preparation method of the 6-series aluminum medium-temperature ultrasonic cleaning agent. Compared with the prior art, the cleaning agent has the advantages that various nonionic surfactants in the cleaning agent are matched with the cleaning aid, so that interfacial tension can be obviously reduced, oil stains can be quickly stripped, and the cleaning agent is resistant to acid and alkali environments, free of layering, stable in finished product, resistant to hard water, free of influence on the cleaning effect and capable of being used in a medium temperature range.

Description

technical field [0001] The invention belongs to the cleaning agent field, and in particular relates to a 6-series aluminum medium-temperature ultrasonic cleaning agent and a preparation method thereof. Background technique [0002] The main elements of 6-series aluminum alloys are magnesium and silicon, and the main strengthening phase is Mg2Si, which can be strengthened by heat treatment. The alloy has the advantages of medium strength, high corrosion resistance, no tendency of stress corrosion cracking, good welding performance, constant corrosion performance of welding zone, good formability and process performance, etc. [0003] The purpose of metal cleaning is to remove the grease on the metal surface and provide a clean metal surface for electroplating, painting and other metal protection treatments. Metal surface cleaners can be divided into water-based cleaners and solvent cleaners. Water-based metal cleaning agent can not only remove oil stains on the metal surfac...

AI Technical Summary

Problems solved by technology

The ultrasonic cleaning agent is the first choice of water-based cleaning agent, because the ultrasonic cleaning machine has a process of heating up and oscillating during work, and the solvent-based cleaning agent is not as stable as the water-based cleaning agent, which may lead to accidents

[0005] At present, the following problems generally exist in metal water-based cleaning agents: the product is unstable, easy to delaminate, insufficient cleaning ability at medium temperature, and has a certain degree of corrosion on 6-series aluminum, which affects the quality and aesthetics of the workpiece

Hydrocarbon cleaners have a strong smell, are flammable, have a limited drying speed, and have a low flash point. Pay attention to ventilation, fire prevention and explosion-proof measures for cleaning equipment and surrounding places. Antistatic measures are required if ultrasonic equipment is used. Prolonged contact with the skin can cause Excessive skimming

[0006] Therefore, the existing cleaning agents cannot meet the ultrasonic cleaning requirements of 6-series aluminum
