Problems solved by technology

[0002] In industry, for the cleaning and removal of obstinate oil stains attached to metal surfaces / other hard surfaces, physical cleaning, hydrocarbon solvent washing or even high-temperature flame burning are generally used to remove them. These cleaning methods will not only cause waste solvents and residues Emission pollution, and it is often difficult to completely remove the stubborn oil stains. In addition, physical cleaning and high-temperature burning can easily damage the substrate structure

Embodiment 1

[0029] Add 58kg of deionized water, 8.5kg of polyoxyethylene polyoxypropylene block copolymer with a molecular weight of 1000-5000, and 4.5kg of imidazoline surfactant into a 200L reactor and stir at a low speed for 40min to obtain the first mixture.

[0030] Add 15 kg of deionized water, 3 kg of sodium lauroyl sarcosinate, 2 kg of pyridinium salt-type cationic surfactant, and 0.2 kg of isothiazolinone fungicide into a 40 L premixing tank and stir at medium speed for 20 minutes to obtain the second mixture.

[0031] Add 8.4 kg of deionized water, 0.3 kg of disodium ethylenediamine tetraacetate, and 0.1 kg of sodium carbonate into a 20 L premixing kettle and stir at high speed until completely dissolved to obtain a third mixture.

[0032] Finally, under stirring, the second mixture and the third mixture were successively added into the 200L reactor of the first mixture, stirred at a medium speed for 20 minutes, and then filtered to obtain about 100 kg of the finished cleaning ag...

Abstract

The invention provides a hard surface hydrophilic protective film cleaning agent and a preparation method thereof. The hard surface hydrophilic protective film cleaning agent is prepared from the following raw materials in parts by weight: 5-12 parts of a nonionic surfactant; 2-7 parts of an amphoteric surfactant; 1-6 parts of a wetting penetrant; 1-5 parts of a decontamination synergist; 0.1 to 0.3 part of an ion chelating agent; 0.1 to 0.3 part of a bactericide; 0.1 to 0.2 parts of a pH value regulator and 77 to 90 parts of deionized water. The preparation method comprises pre-mixing the nonionic surfactant, the amphoteric surfactant, the wetting penetrant, the decontamination synergist, the ion chelating agent, the bactericide, the pH regulator and the deionized water, and stirring uniformly. The cleaning agent has good ability to remove oil stains and clean hard surfaces, and at the same time adheres to the surface of a substrate to form a layer of a nanoscale hydrophilic isolationfilm, can effectively prevent the accumulation and revival of the oil stains for a period of time, and is safe and efficient.
