Abstract

The invention relates to a water-based normal-temperature rustproof spray cleaning agent. The cleaning agent comprises the following raw materials in percentages by weight: 20-25% of HEDP-4NA ((1-hydroxyethylidene)bis-phosphonic acid tetrasodium salt), 0.5-5% of sodium metasilicate, 5-8% of triethanolamine, 1-5% of monoethanolamine, 2-3% of binary acid, 3-8% of surfactant H-381, 0.2-1% of benzotriazole, and the balance of water. The cleaning agent disclosed by the invention is simple in application method, and obvious in effect; the cleaning agent can be used in high-pressure spray, ultrasonic and soaking modes, and is less in application amount; and the cleaning agent does not corrode metals, and can be used without heating at normal temperature, therefore, the cleaning agent is simple and safe in application, saves energy and working time, and improves the working efficiency.

Description

Antirust spray clean-out system of a kind of water base normal temperature and preparation method thereof

Technical field

The invention belongs to the antirust field of matting, relate to anti-rust cleaning agent, antirust spray clean-out system of especially a kind of water base normal temperature and preparation method thereof.

Background technology

At cleaning industry especially in normal temperature workpiece cleaning, after cleaning, part has corrosion soon, especially the antirust spray clean-out system of water base normal temperature, after cleaning, workpiece does not reach cleaning quality standard-required, not that greasy dirt can't is washed off clearly, be exactly that workpiece is corroded, there is no rust inhibition, also having is exactly after cleaning, to place for some time workpiece just to start variable color.

Summary of the invention

The object of the invention is to overcome the deficiency of existing technology, and provide a kind of safety, environmental protection, the saving energy, harmless antirust spray clean-out system of normal temperature and preparation method thereof, this clean-out system does not corrode aluminium, copper, iron and steel parts, and can increase the light of workpiece, and the power of greasy dirt washing at normal temperatures reaches spray clean-out system quality standard and can reach the antirust requirement of inter process.

The technical scheme that the present invention realizes object is:

The antirust spray clean-out system of water base normal temperature, its raw material forms and weight percentage ranges is respectively:

And described tensio-active agent H-381 is isomery fatty alcohol-polyoxyethylene ether.

A preparation method for the antirust spray clean-out system of water base normal temperature, the step of preparation is as follows:

(1) reaction water gaging is added in reactor, between 25-40 ℃, add metasilicate pentahydrate sodium, HEDP-4NA to be stirred to whole dissolvings, then add tensio-active agent H-381 to stir 20 minutes, form solution A;

(2) in another reactor, add trolamine, Monoethanolamine MEA BASF, diprotic acid, the benzotriazole of reacting weight, at 40-60 ℃, react, until react completely, in reaction process, keep temperature of reaction 40-60 ℃, obtain solution B;

(3) above-mentioned A, two kinds of solution of B are carried out to hybrid reaction to transparent liquid, become the antirust spray clean-out system of water base normal temperature.

Advantage of the present invention and beneficial effect are:

1, the present invention is weakly alkaline normal temperature anti-rust cleaning agent, organic additive, inorganic assistant agent, rust-preventive agent, emulsifying agent and tensio-active agent, consists of, and raw materials used wide material sources, obtain easily, and usage quantity is few, is applicable to large-scale explained hereafter.

2, the simple science of the mechanism of action of the present invention, first be that selected raw material also can keep very low foam after composite, after composite, the various performances of each raw material are all enhanced and improve, and wherein metasilicate pentahydrate sodium provides stable pH value, play the effect of protection corrosive protection of aluminium alloy erosion; Tensio-active agent H-381 and metasilicate pentahydrate sodium can play the greasy dirt effect that disperses of cleaning; Trolamine, Monoethanolamine MEA BASF, diprotic acid, benzotriazole can be worked in coordination with antirust and protection to metal.

3, the present invention can normal temperature cleans, and has antirust function, metal is not corroded, and can increase workpiece brightness, and after cleaning, workpiece makes clean-out system reach best effect without hickie by the above mechanism of action, and uses simply, cleans, antirustly once completes.

4, using method simple effects of the present invention is obvious, can high-pressure spraying, ultrasonic wave, immersion used, usage quantity is low, corroding metal not, normal temperature just can be used and need not heat, use simple, safety, save energy, saving man-hour, increases work efficiency.

Embodiment

Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.

First explanation, the raw materials used commercially available prod that is of the embodiment of the present invention, wherein, tensio-active agent H-381 is isomery fatty alcohol-polyoxyethylene ether, is the product of Nanning City Zheng Yao company limited production.

Embodiment 1:

The antirust spray clean-out system of water base normal temperature, its raw material forms and weight percent is respectively:

A preparation method for the antirust spray clean-out system of water base normal temperature, step is as follows:

(1) reaction water gaging is added in reactor, between 25-40 ℃, add HEDP-4NA, the metasilicate pentahydrate sodium of reacting weight, keep reaction 20 minutes, then add tensio-active agent H-381 to keep reaction 20 minutes, obtain solution A;

(2) in reactor, add again trolamine, Monoethanolamine MEA BASF, diprotic acid, benzotriazole reaction to completely, in reaction process, keep temperature of reaction kettle 40-60 ℃, continue to stir 3 hours, until solution is as clear as crystal, obtain solution B;

(3) above-mentioned two kinds of A, B solution are mixed and reacted to transparent liquid, become the antirust spray clean-out system of normal temperature.

Application example: the first liquid bath is in the concentration of water and the antirust spray clean-out system of normal temperature ratio 20:1 (the antirust spray clean-out system of normal temperature that adds embodiment 1), the metal parts (aluminium, copper and cast iron subassembly) that need are cleaned is placed in spray cleaning equipment, regulate spray pressure 0.3MPa, cleaning temperature is controlled at 25-30 ℃, adjust spray cleaning equipment streamline travelling speed, start spray and clean, make the effective spray time of metal parts be controlled at 1 minute, then use hot blast drying.The second groove is in the concentration of water and the antirust spray clean-out system of normal temperature ratio 25:1 (the antirust spray clean-out system of normal temperature that adds embodiment 1), and spray rinsing 1 minute, then uses hot blast drying.
