Description

A kind of preparation method of the aqua type metal cleaner of high-efficiency environment friendly antirust

Technical field

The invention discloses a kind of preparation method of the aqua type metal cleaner of high-efficiency environment friendly antirust, belongs to metal cleaning Agent preparing technical field.

Background technology

In the maintenance and repair of machining and plant equipment, automobile etc., cleaned using diesel oil, coal Water Oil Or Gas mostly Liquid is cleaning part.This not only wastes the energy, and there is potential unsafe factor, careless slightly, then may lead to fire. In recent years, a kind of new metal cleaner is gradually widely used, and it being capable of diesel oil substitute, kerosene and vapour well Oil using safety, is well suited for mechanized cleaning operation cleaning part, and low price.It can be washed for metal, and Rust staining is not had, here it is so-called metal cleaner.

Metal cleaner refer to go to degrease for metal material surface, oils and fatss, dirt with industrial cleaning agent or greasy dirt clean Agent.Metal cleaner is usually used in surface degreasing before and after intermetallic composite coating, scale removal and finished product in the industrial production using quite varied Cleaning before assembling or packaging.In the electronics industry, also must be washed away using abluent after printed circuit plate weld harmful Residue.Additionally, also usually using metal cleaner during plant equipment maintaining.

Water base metal cleaning agent is by means of the moistening of surfactant, emulsifying agent, the penetrating agent for containing etc., emulsifying, oozes Thoroughly, dispersion, solubilising etc. act on realizing the cleaning dirty to metal surface greasy dirt, oils and fatss, wax.Aqua type metal cleaner is added with each Additive is planted, such as builder, stabilizer, defoamer, solubilizing agent industrial chemicals compounding is formed, made by dispersant of water when using Basis.

Various metal cleaners commonly used at present, generally all contain various poisonous and harmful substances, such as sodium nitrite Corrosion is caused to more active metal, follow-up processing is affected, while environment can be polluted, it is easy to the body of operator Damage.

The content of the invention

Present invention mainly solves technical problem：Contain for various metal cleaners commonly used at present various poisonous Harmful substance, easily causes corrosion to more active metal, pollutes the problem of environment and human injury, there is provided one kind Hard Fat Acid, Oleic acid, monoethanolamine, triethanolamine reaction prepare anion surfactant organic amine fatty acid soaps, to remove metal Surface polarity dirt, by it and the nonionic surfactant starch base dodecyl that can effectively remove metal surface oily dirt Glucosides is compounded, and adds the emulsion dispersion that each component in water-soluble polyol ether, solubilized abluent promotes greasy dirt, adds Cortex cocois radiciss oils and fatss Fat diglycollic amide, fatty alcohol-polyoxyethylene ether strengthen dirt-removing power and stably calcium soap and magnesium soap, addition as hard water stabilizer Corrosion inhibiter sodium benzoate protects metal, then adds dirt-removing power and cleaning effect that washing assisant sodium metasilicate improves surfactant Rate, uniform rear addition defoamer dimethyl siloxane to be mixed, is obtained a kind of aqua type metal cleaner of high-efficiency environment friendly antirust, Clean environment firendly of the present invention, corrosion is not resulted in metal, to human body and environment non-hazardous, with vast potential for future development.

In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：

（1）30~40g rice hull ash is weighed, adds 50~80mL mass fractions to be in 10% hydrochloric acid solution, in 90~95 DEG C of thermostatted waters Under bath, 2~3h is stirred with 300~400r/min, filtered, be washed with deionized filtering residue to cleaning mixture in neutrality, proceed to 110~ It is dried to constant weight in 120 DEG C of drying baker, takes out, adds 240~320mL mass fractions to be in 10% sodium hydroxide solution, 95~ Under 100 DEG C of waters bath with thermostatic control, 2~3h is heated, filtered, sodium hydrate regulator solution modulus is added in filtrate to 0.5~0.7, React after 1~2h at 60~65 DEG C, it is 45~55% to solid content to be placed in evaporation and concentration on Rotary Evaporators, is cooled to 30~35 DEG C, 2~3h is stood, centrifugation in centrifuge is added, take precipitation and insert dry 1~3h, get Wu Shui in 50~60 DEG C of drying baker Sodium metasilicate crystal, it is standby；
