Problems solved by technology

[0002] In the known technology, there are basically two traditional methods for degreasing and derusting the surface of metal materials and metal products. One is to use manual cleaning of oil stains and scraping with a knife or metal brush. Rust is not only labor-intensive, requires a lot of manpower, and has low efficiency, but also rust dust caused by rust removal is flying everywhere, polluting the surrounding environment
This method is only suitable for the pretreatment of metal surfaces with less serious oil stains and rust spots, but it is difficult to remove a large amount of oil stains and rust spots on the metal surface
Another method is to use strong alkali to remove oil and strong acid to remove rust. The first method needs to build two operation pools, which takes up a lot of space; the second is troublesome cleaning, slow speed and low efficiency; Especially when cleaning, you must be careful, because the use of strong alkali and strong acid is harmful to the human body and there are hidden dangers of unsafety
In particular, the use of high-strength hydrochloric acid has a sour taste of harmful toxins, which has a strong sense of stimulation to the human body, and the acid mist produced seriously pollutes the air; fourth, the discharge of waste acid water seriously pollutes water resources, affecting and destroying the reliability of water resources. sustainable development
Fifth, the metal surface cleaned by high-concentration hydrochloric acid can produce...

Embodiment 1

[0029] The raw materials of the high-efficiency, environmentally-friendly, oil-removing, rust-removing and scale-removing agent provided in this embodiment are: hydroxyethylidene diphosphonic acid 10%, citric acid 10%, phosphoric acid 15%, oxalic acid 8%, nano-deoiling emulsifier 20%, anticorrosion 1% of the agent, 0.5% of the essence, and the balance of pure water.

[0030] The raw materials were dissolved in the water heated to 70°C by stirring according to the amount taken, and the stirring speed was 100r / min.

[0031] Put the phosphoric acid aqueous solution into the reactor, control the speed of the reactor to 50r / min, put the hydroxyethylidene diphosphonic acid aqueous solution, the citric acid aqueous solution and the oxalic acid aqueous solution into the reactor successively, stir for 40min; then put the nano degreasing emulsifier Put the aqueous solution into the reactor, control the speed of the reactor to 80r / min and stir for 40min; finally adjust the speed of the reacto...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that the raw materials of the high-efficiency and environmentally friendly degreasing, rust, and scale removal agent provided by this embodiment are: hydroxyethylidene diphosphonic acid 12%, citric acid 7%, phosphoric acid 22%, 6.5% oxalic acid, 24% nano-degreasing emulsifier, 0.8% preservative, 0.1% flavor, and the balance of purified water.

Embodiment 3

[0035] The difference between this embodiment and Embodiment 1 is that the raw materials of the high-efficiency and environmentally friendly degreasing, rust, and scale removal agent provided by this embodiment are: hydroxyethylidene diphosphonic acid 3%, citric acid 14%, phosphoric acid 12%, 14% oxalic acid, 15% nano-degreasing emulsifier, 1% preservative, 0.05% flavor, and the balance of pure water.

Abstract

The invention provides an efficient and environment-friendly oil-removing, rust-removing and descaling agent and a preparation method thereof. The efficient and environment-friendly oil-removing, rust-removing and descaling agent is composed of following raw materials: 1-15% of hydroxyethylidene diphosphonic acid, 5-18% of citric acid, 8-25% of phosphoric acid, 4-18% of oxalic acid and 10-30% of nano oil-removing emulsifier. With the adoption of the efficient and environment-friendly oil-removing, rust-removing and descaling agent, various oil dirt, wax, oxides, oxide skins, welding spots, rust and the like can be completely cleaned; the treatment time is short and is rapider and more convenient; the efficient and environment-friendly oil-removing, rust-removing and descaling agent does not contain strong acids, strong alkalis and organic solvents and has low environmental pollution; the efficient and environment-friendly oil-removing, rust-removing and descaling agent has no stimulation and no damages on a human body and is safer and more reliable to use.

Description

Technical field [0001] The invention relates to a cleaning agent, in particular to a high-efficiency environmentally friendly degreasing, rust, and scale removal agent and a preparation method thereof. Background technique [0002] In the known technology, there are basically two traditional methods for removing oil and rust on the surface of metal materials and metal products. One is to manually clean the oil and use a knife or metal brush to remove the oil. Rust is not only labor-intensive, requires a lot of manpower, and is low in efficiency, but the rust dust caused by rust removal is flying everywhere, causing pollution to the surrounding environment. This method is only suitable for the pretreatment of metal surfaces with less serious oil stains and rust spots, but it is difficult to remove a large amount of oil stains and rust spots on the metal surface. Another method is to use the two cleaning procedures of strong alkali to remove oil and strong acid to remove rust. The...
