Degreasing cleaning agent of mechanical equipment and preparation method of degreasing cleaning agent

Abstract

The invention discloses a degreasing cleaning agent of mechanical equipment and a preparation method of the degreasing cleaning agent. The degreasing cleaning agent is prepared from the following raw materials in parts by weight: 20 to 25 parts of sodium metasilicate anhydrate, 15 to 20 parts of polyepoxysuccinic acid, 13 to 16 parts of triethanolamine, 9 to 13 parts of sodium benzoate, 8 to 12 parts of ammonium sulfate, 7 to 11 parts of copper oxide, 6 to 10 parts of methyl benzotriazole, 5 to 9 parts of hydroxypropyl methyl cellulose, 4 to 8 parts of sulfate, 3 to 7 parts of silicate and 25 to 30 parts of deionized water. The preparation method comprises the following steps of S1, putting the sodium metasilicate anhydrate, the polyepoxysuccinic acid, the triethanolamine, the sodium benzoate, the ammonium sulfate and the sulfate in a stirring vessel, then mixing and stirring, rising the temperature to 65 to 85 DEG C after uniformly stirring, and cooling to room temperature after reacting for 50 to 60 minutes, thus obtaining a mixed solvent; S2, adding the copper oxide, methyl benzotriazole, the hydroxypropyl methyl cellulose, the silicate and the deionized water in the mixed solvent, and stirring under 60 to 70 DEG C for 20 to 30 minutes. The degreasing cleaning agent of the mechanical equipment, disclosed by the invention, has excellent degreasing effect, and the mechanical equipment is prevented from being corroded; the preparation method disclosed by the invention is simple, and the cost is low.

[0002] The cleaning of mechanical equipment refers to an indispensable process link in the process of processing, assembling, storing and maintaining mechanical equipment; after a period of normal operation of the equipment, the reverse osmosis membrane elements will be affected by the suspended solids or insoluble substances that may exist in the feed water. Salt pollution, the most common of which are calcium carbonate precipitation, calcium sulfate precipitation, metal oxide precipitation, silicon deposits, inorganic or organic deposition mixtures, synthetic organic matter; due to the considerable amount of mechanical equipment used, so for such machinery The workload of equipment cleaning and the amount of cleaning agent used will definitely increase accordingly; general mechanical equipment cleaning agents contain concentrated lye, although the cleaning effect is obvious, it is severely corrosive to mechanical equipment, and general mechanical equipment The cleaning agent also contains a penetrant, which is a non-ionic surfactant, which is harmful to the environment and the human body. For example, the penetrant JFC series is very corrosive, and the waste alkali is colored and difficult to recycle. The waste water contains Phenol is toxic and has basically been discontinued. In addition, most general cleaning agents use foam-type cleaning agents. Although they can effectively remove impurities such as oil stains, foam-type cleaning agents will increase the oxidation and corrosion of metal surfaces. Caused some damage to the surface of the equipment
