preparation example Construction

[0039] The preparation method of the triisopropanolamine n-heptanoate soap of the embodiment of the application comprises the following steps:

[0040] (1) 21% n-heptanoic acid is dropped into the reactor, and the temperature is raised to 80° C. for subsequent use;

[0041] (2) slowly drop 79% triisopropanolamine into the reactor, and react at 125° C. for 3 hours,

[0042] (3) stop heating, naturally cool to room temperature, discharge, and make n-heptanoic acid triisopropanolamine soap.

[0043] The N-heptanoic acid triisopropanolamine soap prepared by the embodiment of the present application is detected by infrared spectrogram and proton nuclear magnetic resonance spectrum, and the results are as follows: Figure 1~2 as shown, Figure 1~2 Illustrate that the embodiment of the present application successfully prepares triisopropanolamine n-heptanoate soap.

Embodiment 1

[0046] The embodiment of the present application provides the preparation method of the first metal cleaning agent:

[0047] Based on the total mass of the metal cleaning agent, 8% by mass percentage of triisopropanolamine n-heptanoate soap, 2% by mass percentage of isomeric tridecyl alcohol polyoxyethylene ether, 1% by mass percentage of triisopropanolamine n-heptanoate, Dialkylbenzenesulfonic acid triethanolamine salt, potassium palmitoleate with 2% by mass, sodium hydroxide with 1% by mass, anhydrous sodium metasilicate with 4% by mass, 1% by mass sodium citrate, 1% sodium gluconate by mass percentage, and 80% deionized water. Stir well with a mixer until well mixed, labeled as Example 1.

Embodiment 2

[0049] The embodiment of the present application provides the preparation method of the second metal cleaning agent:

[0050] Based on the total mass of the metal cleaning agent, 6% of triisopropanolamine n-heptanoate soap, 4% of isomeric tridecyl alcohol polyoxyethylene ether, and 1% of triisopropanolamine n-heptanoate were added successively, and 1% of Dialkylbenzenesulfonate triethanolamine salt, 3% by mass percent of potassium palmitoleate, 1% by mass of sodium hydroxide, 3% by mass of anhydrous sodium metasilicate, 1% by mass Sodium citrate, 2% sodium gluconate by mass percentage, 79% deionized water. Stir well with a mixer until well mixed, labeled as Example 2.

Abstract

The invention belongs to the technical field of metal cleaning agents, and particularly relates to a metal cleaning agent and a preparation method thereof. In a first aspect, the invention provides the metal cleaning agent which comprises triisopropanolamine n-heptanoate soap, iso-tridecanol polyoxyethylene ether, triethanolamine dodecylbenzene sulfonate, potassium palmitate, an alkaline additive,an organic solvent, a chelating agent and water. The structural formula of the triisopropanolamine n-heptanoate soap is shown as a formula I in the specification. In a second aspect, the invention provides the preparation method of the metal cleaning agent, which comprises the step of mixing the triisopropanolamine n-heptanoate soap, the iso-tridecanol polyoxyethylene ether, the triethanolamine dodecylbenzene sulfonate, the potassium palmitate, the alkaline additive, the organic solvent, the chelating agent and the water to obtain the metal cleaning agent. According to the metal cleaning agent and the preparation method thereof, the defect that generally, existing metal cleaning agents cannot have corrosion inhibition, cleaning performance, no / low foam, alkali resistance and hard water resistance at the same time is effectively overcome.

Description

technical field [0001] The application belongs to the technical field of metal cleaning agents, in particular to a metal cleaning agent and a preparation method thereof. Background technique [0002] Metal materials are easily contaminated by liquids, solids and gases during production, use and storage. The cleaning process is to remove these pollutants through physical, chemical and mechanical means, so that the metal material can regain a certain degree of cleanliness, which is convenient for further surface processing and treatment. [0003] In my country, chemical cleaning is mainly used. Among them, water-based metal cleaning agents are widely used because they are safe, non-toxic, easy to use and cheap. An excellent water-based metal cleaning agent needs to be able to clean most of the dirt and at the same time have a certain anti-corrosion function. With the rapid development of surfactants and the maturity of cleaning technology, water-based metal cleaning agents h...
