Problems solved by technology

At present, the degreasing agents used in the market are mainly phosphoric acid series, which are compounded with phosphate, alkylbenzene sulfonic acid, OP emulsifier, TX emulsifier, etc. In this type of products, a large amount of phosphate is used to cause pollution to the water environment. Nutritional, alkylbenzene sulfonic acid is difficult to degrade in nature, while OP and TX emulsifiers are difficult to degrade, and the residues have a great impact on the human body. At present, it has been restricted and prohibited in many countries
These products, while degreasing and decontaminating, have also created a new problem, that is, they are difficult to decompose in nature and cause long-term impact on the environment

Embodiment 1

[0020] Embodiment 1: a kind of environment-friendly metal surface degreaser, is made of the component of following mass percent:

[0021] Saponin 20%, fatty acid amide 10%, sodium hydroxide 15%, sodium phytate 2%, and the balance is water.

[0022] A preparation method of an environment-friendly metal surface degreasing agent, comprising the following steps:

[0023] Saponin, fatty acid amide, sodium hydroxide, sodium phytate and water are mixed sequentially according to the above mass percentages, stirred at 60° C. for 40 minutes, left to cool to obtain the product.

[0024] Verification: Take the product of this example and dilute it 5 times with water according to the volume ratio, add it to the ultrasonic cleaning tank, turn on the ultrasonic wave at room temperature, put the steel workpiece containing machine oil, cutting oil, and butter into the tank, take it out for 5 minutes, take it out, and rinse it with water Just clean, the degreased workpiece is clean, no oil sta...

Embodiment 2

[0025] Embodiment 2: An environment-friendly metal surface degreasing agent is composed of the following components in mass percentage: 25% saponin, 15% fatty acid amide; 10% sodium hydroxide; 5% sodium phytate, and the balance is water.

[0026] The preparation method of the environment-friendly metal surface degreasing agent in this example is as follows: prepare the raw materials according to the proportion, mix saponin, fatty acid amide, sodium hydroxide, sodium phytate and water in sequence, stir at 50°C for 50 minutes, place and cool to obtain product.

[0027] Verification: Take the product of this example and dilute it 10 times with water according to the volume ratio, add it to the ultrasonic cleaning tank, raise the temperature to 65°C, turn on the ultrasonic wave, put the processed workpiece into the tank, take it out for 3 minutes, rinse it with clean water and then Yes, the degreased cast steel workpiece is clean, without oil stains and greasy feeling. The workpi...

Embodiment 3

[0028] Embodiment 3: a kind of environment-friendly metal surface degreasing agent, is made of the component of following mass percent: saponin 30%, fatty acid amide 8%; Sodium hydroxide 10%, sodium phytate 10%, surplus is water.

[0029] The preparation method of the environment-friendly metal surface degreasing agent in this example is as follows: prepare the raw materials according to the proportion, mix saponin, fatty acid amide, sodium hydroxide, sodium phytate and water in sequence, stir at 75°C for 60 minutes, place and cool to obtain product.

[0030] Verification: Take the product of this example and dilute it 20 times with water according to the volume ratio, add hot water and stir evenly, without limiting the temperature, manually scrub the large-scale equipment, observe the degreasing effect, after washing, scrub with clean water at room temperature, and check whether there are traces of oil slick in the water. Just rinse with clean water, the degreased ductile iro...

Abstract

The invention provides an environment-friendly type metal surface degreasant. The environment-friendly type metal surface degreasant is composed, by weight, ten percent to 30 percent of saponin, five percent to 15 percent of fatty acid amide, five percent to 15 percent of sodium hydroxide, two percent to ten percent of sodium phytate, and the balance water. The environment-friendly type metal surface degreasant is efficient, economical and environmentally friendly. According to the environment-friendly type metal surface degreasant, the metal surface can be rapidly degreased, short-term interprocess corrosion can be carried out on the metal surface, and the environment-friendly type metal surface degreasant is easy to use, safe, efficient, free of peculiar smell and low in foam. The environment-friendly type metal surface degreasant has the advantages of being simple in waste liquid treatment and the like, and the degreasant is an ideal product which is green and clean in production. The invention further provides a manufacturing method of the environment-friendly type metal surface degreasant. The production process is simple, and the cost is low. In addition, the invention provides a method for using the environment-friendly type metal surface degreasant. Degreasing can be rapidly carried out at the using temperature from the normal temperature to the high temperature, the environment-friendly type metal surface degreasant can be suitable for scrubbing and flushing large-scale equipment and ultrasonically cleaning a small-type workpiece, and the environment-friendly type metal surface degreasant has the effect of rapidly removing various kinds of grease on the metal surface.
