Aluminum material anti-oxidation composition as well as preparation method and application thereof

Abstract

The invention relates to an aluminum material anti-oxidation composition, which comprises the following components by mass concentration: 35-45% of an aluminum corrosion inhibitor; 5-8% of synthetic ester; 12-17% of an emulsifier; 3-5% of a stabilizer; 8-12% of a cleaning agent; 0.5%-1.5% of a mildew-proof preservative; 2-3% of a defoaming agent; and the balance of deionized water. The antioxidant composition can be used for online treatment of aluminum materials (including but not limited to aluminum or aluminum alloy rod materials, pipes, bars and plates), an effective thin protective film can be formed on the surface of the aluminum material, the corrosion resistance of the aluminum materials can be improved, the surface lubricating performance of the aluminum materials can be improved, and the service life of the aluminum materials is prolonged. And the problems of adhesion and the like of the pipe in the subsequent process are avoided. In addition, the anti-oxidation composition also has a good cleaning effect, can clean impurities or oil stains left on the surface of the aluminum material in the previous processing procedure, can be used as a cleaning liquid for aluminum rod take-up in the continuous casting and rolling production process, provides effective cleaning, lubricating and corrosion resisting effects, and improves the surface smoothness and brightness of the aluminum rod.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and particularly relates to an anti-oxidation composition for aluminum materials and a preparation method and application thereof. Background technique [0002] Due to its light weight and corrosion resistance, aluminum and aluminum alloys are currently widely used and one of the most economical and applicable materials, and aluminum is an active metal, so the surface of aluminum will form an oxide film in the air to prevent metal corrosion. However, since the oxide film naturally formed on the surface of aluminum is thin and not dense, long-term exposure to corrosive media or environment can easily cause pitting corrosion on the surface of aluminum. Therefore, anti-corrosion treatment on the surface of aluminum is to improve its corrosion resistance. an important way.

Problems solved by technology

Patent CN101775596B proposes a simple and rapid chromium-free passivation solution formula and process method, which can indeed improve the corrosion resistance of aluminum tubes, but the passivation solution can only improve the corrosion resistance of the aluminum surface, and cannot During the production process, the surface of the aluminum material is cleaned to remove impurities or oil stains remaining on the surface in the previous processing process, and it cannot increase the lubricating performance of the aluminum material during the processing process. Only pipes with good lubricity can be used in the subsequent There will be no sticking phenomenon in the process of processing or feeding, which is conducive to the smooth flow of the process
