Problems solved by technology

The cleaning object of this invention is only the ink on the hands of printing workers, and the cleaning object is single. It is cleaned by wiping or diluted with water, and the lotion cannot be reused.
[0004] Although the above-mentioned patents all have certain effects in decontamination, they cannot take into account the following four advantages at the same time: one is the repeated use of lotion, the other is the diversification of cleaning objects, and the third is that the content of oil on the cleaning objects is unlimited. , the fourth is the green degradability of the cleaning agent

Embodiment 1

[0034] Embodiment 1: Use n-octane as the oil phase, cleaning solution for metal

[0035] The oil stain used in this example is a viscous bio-oil, which is attached to the surface of the aluminum sheet, deposited for more than 24 hours, and cleaned with the cleaning agent of the present invention, and the cleaning when the viscous oil stain is attached to the surface of the metal material is investigated. Effect.

[0036] (1) Oil sample preparation

[0037] Cut a piece about 3×3cm 2 Aluminum sheets of different sizes were washed, dried and weighed. Apply bio-oil, which is liquid at room temperature, on No. 1 aluminum sheet, dry it in an oven (100°C), and weigh it; calculate the oil content (η) of the aluminum sheet, see formula (1).

[0038] η = m 1 - m o m o × ...

Embodiment 2

[0051] Embodiment 2: Take n-octane as the oil phase, cleaning solution for metal

[0052] The oil stain used in this example is a highly viscous decompression residue, which is attached to the surface of the aluminum sheet, deposited for more than 24 hours, and cleaned with the cleaning agent of the present invention. cleaning effect.

[0053] (1) Oil sample preparation

[0054] The method described in Example 1 was used to prepare an oil-stained aluminum sheet with a vacuum residue content of 13.2%.

[0055] (2) Preparation of cleaning agent

[0056] 1) Weigh 15.00 g of n-octane and 6.15 g of water, and put them into a glass container;

[0057] 2) Weigh 1.50 g of sodium dodecyl sulfate (SDS), 1.50 g of octadecyltrimethylammonium chloride (OTAC), and 1.50 g of decyl glucoside, mix them uniformly, add them to the above container, and shake them fully;

[0058] 3) Weigh 3.60g of n-butanol, 0.15 pieces of sodium chloride, 0.15g of builder-sodium tripolyphosphate, and 0.3g of ...

Embodiment 3

[0062] Embodiment 3: Use n-octane as the oil phase, cleaning solution for metal

[0063] The oil stain used in this embodiment is a relatively viscous atmospheric residue, which is attached to the surface of the aluminum sheet, deposited for more than 24 hours, and cleaned with the cleaning agent of the present invention. cleaning effect.

[0064] (2) Oil sample preparation

[0065] The method described in Example 1 was used to prepare an oil-stained aluminum sheet with an atmospheric residue content of 14.3%.

[0066] (2) Preparation of cleaning agent

[0067] 1) Weigh 12.00 g of n-octane and 12.38 g of water, and put them into a glass container;

[0068] 2) Weigh 0.90 g of sodium dodecyl sulfate (SDS), 0.90 g of octadecyltrimethylammonium chloride (OTAC), and 0.60 g of decyl glucoside, mix them uniformly, add them to the above container, and shake them fully;

[0069] 3) Weigh 3.00g of n-butanol, 0.05g of sodium chloride, 0.09g of builder-sodium tripolyphosphate, and 0.0...

Abstract

The invention provides an oil dirt powerful cleaning agent and a preparation method thereof. The oil dirt cleaning agent comprises the following components in parts by weight: 35-50 parts of oil, 21.5-53.5 parts of water, 1-5 parts of cationic surfactant, 1-5 parts of anionic surfactant, 1-5 parts of nonionic surfactant, 8-12 parts of cosurfactant n-butyl alcohol, 0-0.5 part of sodium chloride and 0.5-1 part of builder sodium tripolyphosphate. The oil dirt cleaning agent has the beneficial effects that the oil dirt cleaning agent uses compound microemulsion of the anionic / cationic surfactant with stronger solubilizing capacity and the nonionic surfactant with degradability as mother liquor and adopts several property assistants, so that the oil dirt cleaning agent achieves the advantages of rust prevention and decontamination, multiple reutilization of the lotion and environment friendliness, does not have limits to the oil content and has great economic value; meanwhile, the oil dirt cleaning agent also achieves diversification of cleaning objects, can be used for the materials, such as metals, glass, plastics, cloths, leather, ceramics and rubber and has a better application prospect.

Description

technical field [0001] The invention belongs to the field of environmental engineering, and in particular relates to an oily dirt cleaning agent, in particular to a recyclable oily dirt cleaning agent and a preparation method thereof. Background technique [0002] In daily life and industrial production, oily dirt is ubiquitous. Affected by Chinese cooking methods, the surfaces of glass, porcelain, gas stoves, range hoods and other utensils in the kitchen environment are often covered with a layer of oily dirt, and the components of these oily dirt are mainly oily polymers formed by cooking. Offset printing ink is an indispensable raw material for printing. The main component of the ink is vegetable oil solvent. Therefore, the surface of the wet roller, screen and other components during the printing process is easily contaminated with ink and corroded. In the vehicle oil circuit system, during the use of fuel oil, the surface of other components such as fuel tanks and oil ...
