A kind of metal cleaning agent and preparation method thereof

Abstract

The invention relates to a metal cleaning agent and a preparing method thereof. Raw materials of the metal cleaning agent include 1%-20% of an organic solvent, 1%-5% of a corrosion inhibitor, 1%-7% ofan emulsifying agent, 1%-5% of a penetrating agent, 1%-10% of a dispersing agent, 1%-5% of a washing assisting agent, 1%-10% of a surface active agent, 0.5%-3% of a chelating agent and the balance water. The preparing method includes the following steps that the washing assisting agent and the organic solvent are evenly mixed, then the surface active agent, the dispersing agent, the emulsifying agent, the corrosion inhibitor, the penetrating agent, the chelating agent and the deionized water are added and evenly mixed, and the metal cleaning agent is obtained. The metal cleaning agent has thebeneficial effects that the heavy oil dirt removing capability is high, and the cleaning speed is high; and in addition, the beneficial effects that the metal corrosion resistance is good, and biodegradability is achieved are achieved.

Description

technical field [0001] The present invention relates to a kind of oil cleaning agent, more specifically, it relates to a kind of metal cleaning agent and its preparation method. Background technique [0002] At present, the cleaning agents used to clean metal materials at home and abroad mainly include three categories. The first category is solvent cleaning agent, such as gasoline, kerosene, diesel oil and other solvents, but this type of cleaning agent has been gradually eliminated due to reasons such as waste of energy, inflammability and explosion, and unsafety. The second category is halogenated alkanes cleaning agent, such as 1-1-1 trichloroethane etc., this type of cleaning agent is because of high cleaning cost and uneconomical, thereby limiting its scope of promotion. The third category is water-based cleaning agents. The cleaning agents commonly used at present all have shortcomings such as corrosion to metal surfaces, poor rust resistance, poor rinsing performanc...

AI Technical Summary

Problems solved by technology

The first category is solvent cleaning agents, such as gasoline, kerosene, diesel and other solvents, but such cleaning agents have been gradually eliminated due to energy waste, flammability, explosion, and unsafety.

The second category is halogenated alkanes cleaning agent, such as 1-1-1 trichloroethane etc., this type of cleaning agent is because of high cleaning cost and uneconomical, thus limiting its promotion scope

The third category is water-based cleaning agents. The cleaning agents commonly used at present all have shortcomings such as corrosion to metal surfaces, poor rust resistance, poor rinsing performance, poor biodegradability, toxicity, and excessive phosphorus content, which cannot well meet the production requirements. process requirements

Because aluminum itself is relatively active, the existing cleaning agents usually use highly acidic or alkaline cleaning solutions in order to have a good cleaning effect. In this way, the cleaning process is more corrosive to aluminum, which to a certain extent causes aluminum Loss

Moreover, the cleaning effect of the existing cleaning agents is not very satisfactory, especially for metal parts with heavy oil stains, the aluminum material after cleaning is prone to black surface layer, which brings troubles to subsequent processing, especially for the processing of precision components cause confusion

In addition, the existing cleaning agent is highly corrosive to the equipment, which increases the cost of the equipment

At the same time, these cleaning agents have a long cleaning time, requiring 10 to 30 minutes of cleaning time, and have poor rinsing properties
