Aluminum alloy die-cast surface cleaning agent and preparation method thereof

Abstract

The invention discloses an aluminum alloy die-cast surface cleaning agent, comprising the following components based on 100 parts by weight in total weight: 10-15 parts of nonylphenol polyoxyethylene ether, 2-8 parts of lauryl diethanolamide, 6-18 parts of dodecyl dimethyl betaine, 8-16 parts of cetyl sodium sulfate, 1-5 parts of benzotriazole, 2-6 parts of sodium silicate, 4-6 parts of coconutt diethanol amide, 8-12 parts of sodium gluconate, 2-4 parts of span-80 and the balance of water. The invention also discloses a preparation method of the aluminum alloy die-cast surface cleaning agent. The aluminum alloy die-cast surface cleaning agent has the advantages of high cleanness, high anti-rust capability, low foam and low-temperature cleaning, is effective for nonferrous metal alloys, and in particular for die-casting alloys, and is simple in process, free of phosphate and nitrite, easy to biodegrade and environment-friendly.

Description

technical field [0001] The invention relates to the field of metal cleaning agent treatment, in particular to an aluminum alloy die casting surface cleaning agent and a preparation method thereof. Background technique [0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. Because the die-casting processing method can obtain better alloy properties, in recent decades, die-casting technology has developed rapidly both at home and abroad. [0003] Die-casting coating is indispensable in the production process, and it has a major impact on the service life of the die-casting mold, the quality of the casting and the production efficiency. There are many types of die-casting coatings, including water-based die-casting coatings, oil-based die-casting coatings, etc. The die-casting coating is beneficial to the production and the improvement of product quality and performance during the die-casting process,...

AI Technical Summary

Problems solved by technology

The die-casting coating is beneficial to the production and the improvement of product quality and performance during the die-casting process, but if the production cycle is long, or the casting is placed in the warehouse for a long time, the die-casting coating will adhere to the surface of the alloy, and the surface of the alloy will be prone to dirt Long hair, spots, discoloration, rust, etc., will have adverse effects on the performance and appearance of castings, and even make die castings scrapped

[0004] At present, there are few surface cleaners specifically for aluminum alloy die-casting parts on the market. Most of them can only simply remove oil or rust, and cannot clean and remove aluminum alloy die-casting coatings.

Traditional alloy surface cleaning agents have been difficult to meet the current requirements for surface cleaning of aluminum alloy die castings
