Embodiment 1

[0023] A preparation method of a high-flash-point hydrocarbon cleaning agent for removing dirt from crevices, comprising the steps of:

[0024] Weigh respectively undecane with a volume of 90 and diethylene glycol tert-butyl ether with a volume of 10, and then mix them to obtain a mixed solution. When mixing, undecane can be added to the reactor first, and then Then diethylene glycol tert-butyl ether was added. Stir the mixed solution at 55-60° C. for 15-25 minutes to obtain the cleaning agent, and the stirring speed is 50-70 revolutions / min.

Embodiment 2

[0026] A kind of preparation method of the high-flash-point hydrocarbon cleaning agent that removes crevice dirt, the difference with embodiment one is:

[0027] Undecane with a volume of 10 and diethylene glycol tert-butyl ether with a volume of 90 were respectively weighed, the stirring temperature was 60° C., the stirring time was 20 min, and the stirring speed was 60 rpm.

Embodiment 3

[0029] A kind of preparation method of the high-flash-point hydrocarbon cleaning agent that removes crevice dirt, the difference with embodiment one is:

[0030] Undecane with a volume of 50 and diethylene glycol tert-butyl ether with a volume of 50 were weighed respectively, the stirring temperature was 55° C., the stirring time was 25 min, and the stirring speed was 50 rpm.

Abstract

The invention discloses a high-flash-point hydrocarbon cleaning agent for removing dirt in slits, and a preparation method thereof. The cleaning agent comprises the following raw materials by volume:10 to 90% of undecane and 10 to 90% of diethylene glycol tert-butyl ether. Undecane has very low surface tension and extremely strong penetration capability and can enter small slits; diethylene glycol tert-butyl ether dissolves both water-soluble and oil-soluble dirt; and undecane carries diethylene glycol tert-butyl ether to enter gaps between metal and plastic, and then diethylene glycol tert-butyl ether dissolves and wraps dirt and then carries the dirt out together. The high-flash-point hydrocarbon cleaning agent of the invention can dissolve inorganic substances and organic substances atthe same time and completely remove dirt in slits; and the preparation method is simple in process and easy for mass production.

Description

technical field [0001] The invention relates to the field of cleaning technology, in particular to a high-flash-point hydrocarbon cleaning agent for removing crevice dirt and a preparation method thereof. Background technique [0002] At present, the metal processing industry has successfully combined metal and plastic tightly. When the combined workpiece is subjected to PVD (Physical Vapor Deposition, Physical Vapor Deposition) vacuum plating, dirt will be sucked out at the joint, resulting in a different color of the coating after PVD plating. and shedding and other adverse phenomena. Dirt contains water-soluble inorganic salt components and oil-soluble organic components. Since the gap where the dirt is located is at the nanometer level, ordinary cleaning agents cannot completely penetrate into the gap and bring out the dirt. The Chinese patent with the application number 201710799508.6 discloses a hydrocarbon cleaning agent that removes dirt from crevices. Although it ...
