Abstract

The invention relates to a steel surface spraying process, and particularly relates to a steel surface spraying pretreatment agent. The phosphorus-free degreaser for surface spraying pretreatment of steel is a mixed solution prepared from the following components in mass concentration: 15-30 g/L anhydrous sodium metasilicate, 5-10 g/L sodium carbonate, 4-6 g/L alkylphenol ether sulfosuccinate sodium salt, 2-4 g/L sodium lauryl sulfate, 5-10 g/L fatty alcohol-polyoxyethylene ether, 2-4 g/L isopropanol, 0.2-0.4 g/L defoaming agent FAG470, 0.5-2.5 g/L disodium edetate and the balance of water. The invention can realize thorough degreasing at normal temperature, and is easy to perform cleaning operation and low in foam.

Description

A kind of agent of non-phosphate degreasing of steel surface spraying pre-treatment
Technical field
The present invention relates to steel surface spraying coating process, particularly relate to a kind of steel surface spraying pretreating reagent.
Background technology
The grease-removing agent that current industrial steel surface spraying pre-treatment uses, mostly treatment temp is higher, containing the phosphoric acid salt that can aggravate body eutrophication, affects environment; And agent of non-phosphate degreasing contains cleaning performance after degreasing poor sodium hydroxide, sodium metasilicate, or dosage of surfactant is too high, there is cleaning thoroughly or the too much problem of foam.
In prior art, general containing sodium alkyl benzene sulfonate in grease-removing agent formula, although have very strong emulsifying power and degreasing power, froth stability too strong and also in water calcium ions and magnesium ions be combined the calcium salt being insoluble in water, affect degreasing effect and wash degree.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of steel surface to spray pre-treatment agent of non-phosphate degreasing.Agent of non-phosphate degreasing of the present invention can thoroughly degreasing at normal temperatures, and easily cleans, low bubble.
An agent of non-phosphate degreasing for steel surface spraying pre-treatment, it is by the formulated mixed solution of following component, and in mixed solution, the mass concentration of each component is:
All the other compositions are water.
The agent of non-phosphate degreasing of described a kind of steel surface spraying pre-treatment, in described mixed solution, the mass concentration of each component is preferably:
All the other compositions are water.
The agent of non-phosphate degreasing of described a kind of steel surface spraying pre-treatment, described mixed solution is dissolved in tap water by the above anhydrous sodium metasilicate, sodium carbonate, disodium ethylene diamine tetraacetate, froth breaking king FAG470 is added after stirring and dissolving, then add sodium lauryl sulphate while stirring, after dissolving, add fatty alcohol-polyoxyethylene ether, isopropyl alcohol mixture while stirring.
From formula of the present invention, first, selected alkyl phenol ether sulfo-succinic acid ester sodium salt uniquely, its stability and water tolerance are better than alkylphenol polyoxyethylene, and soluble in water, compatibleness is good again with negatively charged ion, nonionic, have good emulsifying, dispersiveness, wettability, soil release performance, under low temperature, ability of cleaning greasy dirt is strong, and washing (-)off properties is good, foam is few, can produce obvious water-saving result.
Secondly, the sodium lauryl sulphate that the present invention selects, soluble in water, to alkali and hard water insensitive, be a kind of nontoxic anion surfactant, its biological degradability > 90%, can produce good washing effect at low temperatures and washing (-)off properties is good.
To sum up, the present invention can realize good degreasing effect at lower than 35 DEG C, and the material that there is no not easy cleaning after degreasing produces, and tensio-active agent is few, and therefore foam is also few.
