Problems solved by technology

[0004] ① Metal workpieces are prone to corrosion after cleaning, resulting in darkening and blackening of the surface of the workpiece, affecting the smoothness and aesthetics of the metal surface
[0005] ②The cleaning temperature is high, the cleaning efficiency is low, and the cleaning cost is high
[0006] At present, the washing temperature of various ultrasonic wax removers on the market is relatively high, usually around 60°C, the washing energy consumption is relatively large, and the washing time is relatively long, and the use concentration is high; Chinese patent CNCN201010542596.X discloses a fast wax remover, Adopted dienyl succinimide T154 as the oil-soluble dispersant, fatty alcohol polyoxyethylene ether IW and alkanolamide phosphoric acid ester 6503 as the water-soluble dispersant, because T154 is insoluble in water, although it is also an amphiphile, there is Polar base and non-polar base, but they are emulsifiers, which cannot significantly reduce surface tension, are not surfactants, and cannot achieve a good wax removal effect

Embodiment 1

[0037] The present embodiment provides a kind of preparation method of dewaxing degreasing cleaning agent, comprises the following steps:

[0038] S1. Calculate and weigh 89.5wt% water according to the above components, add it into the reaction kettle, start the stirrer to stir, and the stirring speed is 150r / min.

[0039] S2. 4wt% coconut fatty acid diethanolamide, 2wt% fatty alcohol polyoxyethylene ether sodium sulfate, 0.1wt% sodium lauryl sulfate, 4wt% triethanolamine, 0.1wt% sodium pyrophosphate, 0.1 Wt% sodium tripolyphosphate, 0.1wt% benzotriazole and 0.1wt% sodium hydroxymethylglycinate are slowly added to the reaction kettle in turn, and stirred until the liquid is light yellow, uniform and transparent liquid, and finally dewaxing Oil cleaner.

[0040] Among them, the purity of triethanolamine is 85% to 100%, the purity of coconut oil fatty acid diethanolamide is 90% to 100%, the purity of fatty alcohol polyoxyethylene ether sodium sulfate is 70% to 100%, and the pur...

Embodiment 2～ Embodiment 10

[0042] Each component and the mass percentage of each component in Example 2-Example 10 and Comparative Example 1-Comparative Example 5 are different from Example 1, and the specific reaction method is the same as Example 1, and will not be repeated one by one. Table 1 shows the components of the dewaxing and degreasing cleaners of Examples 2-15 and Comparative Examples 1-5 and the mass percentage of each component.

Abstract

The invention relates to a cleaner, and discloses a dewaxing and degreasing cleaner, and a preparation method and an application thereof. The dewaxing and degreasing cleaner comprises triethanolamine, cocoanut fatty acid diethanolamide, polyoxyethylene fatty alcohol sodium sulfate, sodium dodecyl sulfate, complexing agents, metal corrosion inhibitors, preservative and the balance water; the mass ratio of the cocoanut fatty acid diethanolamide, the polyoxyethylene fatty alcohol sodium sulfate and the sodium dodecyl sulfate is 4-10:2-8:0.1-2. In the dewaxing and degreasing cleaner disclosed by the invention, the cocoanut fatty acid diethanolamide, the polyoxyethylene fatty alcohol sodium sulfate and the sodium dodecyl sulfate are creatively used as surfactants, and the surface tension can be reduced effectively through mutual synergistic effect; and in order to ensure that the optimal effect of the surfactants is achieved, other components are selected preferably, and the values of the components are optimized. According to the dewaxing and degreasing cleaner disclosed by the invention, the purposes of dewaxing and degreasing are achieved at 30-40 DEG C, and the effect is good.

Description

technical field [0001] The invention relates to a cleaning agent, more specifically, to a dewaxing and degreasing cleaning agent and its preparation method and application. Background technique [0002] Cleaning operations play an extremely important role in industrial production. Cleaning operations have far-reaching significance for ensuring the appearance and internal quality of metal products (parts), energy consumption during processing, economic benefits and environmental protection and a series of social benefits. [0003] After the metal workpiece is mechanically polished, there will be more wax and oil stains, which need to be cleaned. The following problems are likely to exist during the cleaning process: [0004] ① Metal workpieces are prone to corrosion after cleaning, resulting in darkening and blackening of the surface of the workpiece, affecting the smoothness and aesthetics of the metal surface. [0005] ②The cleaning temperature is high, the cleaning effi...
