Aluminum alloy surface water-base micro emulsion rust protection cleaning agent

Abstract

The invention discloses an aluminum alloy surface water-base micro emulsion rust protection cleaning agent which comprises dodecyl trimethyl benzyl ammonium chloride, fatty acid methyl ester polyoxyethylene ether, an organic solvent, laurate dihydroxyethylamide, ammonium molybdophosphate, siloxane ketone, a builder and polyether modified dimethicone. By compounding the organic solvent, dodecyl trimethyl benzyl ammonium chloride which is a cationic surface active agent, and fatty acid methyl ester polyoxyethylene ether and laurate dihydroxyethylamide which are non-ionic surface active agents, by additionally adopting a chelating agent, a polyether modified organosilicon defoaming agent and an ammonium molybdophosphate corrosion inhibitor, and by combining the permeation and dissolving properties of the organic solvent and the wetting and emulsifying properties of the surface active agents, the aluminum alloy surface water-base micro emulsion rust protection cleaning agent achieves the effect of carrying out water-base micro emulsion cleaning and rust protection on the surface of an aluminum alloy.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy cleaning, in particular to a water-based microemulsion antirust cleaning agent for aluminum alloy surfaces. Background technique [0002] The pollution layer or covering layer formed by the physical, chemical or biological action on the surface of the object is called dirt, and the process of removing these pollutants or covering layer to restore the original surface condition is called cleaning. Aluminum alloy is the most widely used in industry. A class of non-ferrous metal structural materials, which have been widely used in aluminum alloys such as aviation, automobiles, machinery manufacturing, and ships. During the processing and forming of aluminum alloys, stamping oil, drawing oil, cutting fluid, dust, etc. will form various greases and stains on the surface of aluminum alloy materials, which need to be cleaned. Cleaning will affect the subsequent processing, surface condition and A...

Problems solved by technology

During the processing and forming of aluminum alloys, stamping oil, drawing oil, cutting fluid, dust, etc. will form various greases and stains on the surface of aluminum alloy materials, which need to be cleaned. Cleaning will affect the subsequent processing, surface condition and A very important process for product quality. The liquid cleaning agent based on strong alkali has a strong ability to remove dirt, but it has a strong corrosion on the surface of the appliance and is easy to harm the human body; the liquid cleaning agent mainly based on solvent mainly uses dissolution. Remove dirt, but the solvent is flammable, explosive, and unsafe; liquid cleaning agents based on surfactants have low descaling efficiency, need to soak dirt for a long time, and are expensive
