Description

Cleaning anti-rust agent and preparation method thereof

Technical field

The present invention relates to the chemical field, particularly a kind of will the cleaning-antirust cleaning anti-rust agent that unites two into one and preparation method thereof.

Background technology

Inevitably by oil pollution, the metal parts after the pollution must adopt clean-out system to clean to the metal parts of some aluminums or steel when processing or use.There are the following problems to adopt existing clean-out system cleaning: clean the white dot that back metal parts remained on surface has some to cause because of clean-out system 1.; 2. cleaning the back can get rusty again within a short period of time again.The reason that produces the problems referred to above is because existing metal cleaner is to be the aqueous cleaning agent of main component with the tensio-active agent, this clean-out system only has cleaning function and not have rust-preventing characteristic (former: rustless property), and foam is more and can't use high-tension apparatus when causing cleaning, and makes the cleaning inefficiency.Existing in addition purging method processing step is complicated, generally needs cleaning, rinsing, antirust three operations, and the cleaning components time is longer.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art and a kind of cleaning anti-rust agent and preparation method thereof is provided, have simultaneously by the prepared cleaning anti-rust agent of present method and to clean and antirust function, and it is residual and adsorbed one deck in the metallic surface and scold the water anti-rust film to realize rust prevention during manufacture not need rinsing to reach after cleaning to clean the back component not have white.

Realize that technical scheme of the present invention is:

A kind of cleaning anti-rust agent is characterized in that:

Its moiety and weight proportion are respectively:

Edta solution 1～2%

Triethanolamine solution 3～4%

Monoethanolamine MEA BASF solution 0.5～1%

Synthetic acid ester solution 5～10%

Polyacrylic acid solution 5～10%

Triazines microbicide solution 1～3%

All the other add water to 100%.

And the strength of solution of described each moiety is respectively:

Edta solution 50～70%

Triethanolamine solution 97～99%

Monoethanolamine MEA BASF solution 97～99%

Synthetic acid ester solution 65～75%

Polyacrylic acid solution 25～35%

Triazines microbicide solution 85～95%.

A kind of preparation method of cleaning anti-rust agent is as follows:

(1). press proportioning with in 50% the water adding reactor A, be warming up to 35～45 ℃, add edta solution, triethanolamine solution and Monoethanolamine MEA BASF solution respectively by proportioning then and react, and in 40～42 ℃ of temperature ranges, be incubated 3～5 hours, promptly obtain water-based antirust;

(2). in reactor B, add the water of remainder 50%, add polyacrylic acid solution and thorough mixing stirring by proportioning then, and under agitation react by the synthetic acid ester solution of proportioning adding, the reaction times is 30～45 minutes, temperature remains on 10～40 ℃ between the reaction period, obtains reaction solution;

(3). the water-based antirust in the reactor A is added in the reaction solution of reactor B, the temperature that improves reactor B is 40～42 ℃, is incubated and stirs 0.5～1.2 hour;

(4). add the triazines microbicide solution by proportioning in reactor B, stirring promptly became the cleaning anti-rust agent finished product after 20～40 minutes.

Advantage of the present invention and beneficial effect are:

1. the simple science of this cleaning anti-rust agent mechanism of action at first adopts the reaction of organic acid and trolamine and Monoethanolamine MEA BASF to generate a kind of water-based antirust, and the trolamine that is added in it plays and cleans and rust inhibition.The water-based antirust that is generated also needs to add synthetic boric acid ester, sterilant and polyacrylic acid to form cleaning anti-rust agent of the present invention, the synthetic boric acid ester that is wherein added can be cleaning process a stable pH value is provided, the sterilant that is added can suppress bacterium and generate and to make cleaning liquid that corruption not take place, and the polyacrylic acid that is added can play to help and wash and disperse the smeary effect.Thus, the mechanism of action of this clean-out system is at first to be with greasy dirt cleaning, dispersion, emulsification, utilizes the very strong adsorption of rust-preventive agent and intermetallic, and remaining greasy dirt displacement is broken away from the metallic surface, the metallic surface was adsorbed one deck and was scolded the water anti-rust film this moment, and this film has repulsive interaction to water, greasy dirt.Therefore after cleaning, the metallic surface is very clean, does not have smeary residual.

2. this cleaning anti-rust agent uses simple effects obvious, utilize high-pressure spraying can make the scavenging solution usage quantity low, increase work efficiency, clean the back part and do not need rinsing, under high pressure non-foaming, can perfection reach rinsing effect, and part does not need through the rust-preventive agent rinsing after cleaning antirust to realize the effect of rust prevention during manufacture.Therefore the present invention has overcome that clean-out system has the exhibiting high surface promoting agent and the drawback that can not adopt high pressure cleaning is oversimplified numerous and diverse cleaning.

3. this cleaning anti-rust agent is that employing organic acid and tensio-active agent, sterilant are that main raw material is prepared from through the science complete processing, does not need rinsing after the cleaning, washes the no hickie in zero (portion) part surface, back, and is bright as new, and can reach the rust prevention during manufacture requirement.This product is weakly alkaline, and raw materials used wide material sources obtain easily, and usage quantity is few, and slushing oil, oil in water emulsion, cutting fluid, compacting oil, lubricating oil, the processing of transformer wet goods are had strong washing power with oil, is specially adapted to the cleaning rust-proof of steel, aluminium.
