Problems solved by technology

There are also cleaning agents containing phosphates, such as sodium tripolyphosphate and sodium pyrophosphate, but a large number of phosphorus-containing compounds are used, which also has a negative impact on the environment. When the cleaning agent waste liquid containing phosphates is discharged into rivers, lakes and seas, It will cause "over-fertilization" and "rich oxidation" of the water body, which will deteriorate the water quality, affect the growth of aquatic organisms, and seriously pollute the ecological environment of the water area.
Although some cleaning agents do not contain the above substances, they contain more alkaline salts, which are not suitable for cleaning electronic products.

Embodiment 1

[0026] Multifunctional environmental cleaning agent (unit: kg)

[0027] This is an efficient and environmentally friendly cleaning agent suitable for cleaning grease and dirt on various metal surfaces. It can be cleaned at room temperature or at 40-60°C.

[0028] Raw materials: SAS-60 4, AE09 2, AE07 2, LS45 1, propylene glycol 4, N-methylpyrrolidone 6, JFC 1, zeolite 12, JC-863 0.20, water 67.8.

[0029] Preparation:

[0030] 1. Put SAS-60, AE09, AE07, and LS45 surfactants in a stainless steel kettle, add co-solvent propylene glycol and N-methylpyrrolidone under stirring, and stir evenly.

[0031] 2. Put the water in another stainless steel kettle, add the chelating agent under stirring, after the zeolite P is dissolved, add the penetrant JFC and stir evenly.

[0032] 3. Add the homogeneous liquid prepared in 2 to the mixed solution prepared in 1, add the defoamer JC-863 under stirring, and continue stirring for 30 minutes to obtain the product.

Embodiment 2

[0034] Multifunctional environmental cleaning agent (unit: kg)

[0035] This is another high-efficiency and environmentally friendly cleaning agent suitable for cleaning grease and dirt on various metal surfaces. It can be cleaned at room temperature or at 40-60°C.

[0036] Raw materials: SAS-60 1, AES 1, APG 1, LS45 4, butyl glycol ether 4, N-methylpyrrolidone 4, JFC-2 2, layered crystalline sodium disilicate 10, TC-103 0.20, water 72.8.

[0037] The preparation method is the same as in Example 1.

Embodiment 3

[0039] Multifunctional environmental cleaning agent (unit: kg)

[0040] This is an efficient and environmentally friendly cleaning agent suitable for cleaning semiconductor material equipment and liquid crystal displays.

[0041] Raw materials: AES 2, AE09 3, AE07 3, LS45 1, propylene glycol 5, ethylene glycol butyl ether 6, JFC1, modified sodium polyacrylate 6, JC-863 0.1, water 72.9.

[0042] The preparation method is the same as in Example 1.

Abstract

The present invention discloses one kind of green multifunctional detergent comprising surfactants, detergency promoter, permeating agent, chelating agent, defoaming agent and water in certain weight proportion. The green multifunctional detergent is used in cleaning ferrous metals, non-ferrous metals and stainless steel, as well as semiconductor material and device, LCD glass plate, coated glass, LCD box and electronic circuit board. The present invention has the advantages of compounding and use at normal temperature, powerful detergency, high cleaning efficiency, no ODS matter contained, no phosphate contained, no inflammability, no explosion, no pollution, and direct exhaust and reuse of used waste liquid.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a multi-functional environment-friendly cleaning agent and a preparation method thereof, which is suitable for removing oily stains on various metal surfaces, cleaning materials and devices in semiconductor technology, substrate glass, coated glass, etc. in liquid crystal display production. Cleaning of liquid crystal boxes, cleaning of circuit boards after assembly and welding of electronic products, etc. Background technique [0002] At present, there are many kinds of cleaning agents produced in my country. Some cleaning agents contain flammable and explosive low-boiling alcohol hydrocarbons, such as ethanol, isopropanol, gasoline, and kerosene. The operating environment is strict and unsafe during use. Some cleaning agents contain ODS substances that are restricted by the state and eventually banned, such as 1.1.1-trichloroethane, trifluorotrichloroethane (trade name: F113), among which OD...
