Abstract
The present invention relates to an efficient metal scavenger which is composed of (by weight) 1 to 5% of OP-10, 1 to 5% of 6501, 1.5 to 5% of JFC, 1 to 5% of polyether 2020, 5 to 10% of sodium nitrite, 5 to 10% of triethanol amine and water as the rest. The present invention has the advantages of low foam, high efficiency (the cleaning rate is higher than 90%), no corrosion to a metal surface (the rust protection rate reaches 0 grade), high stability and no pollution (no phosphorus or aluminum).
Description
The present invention relates to a kind of washing composition, specifically a kind of washing composition that is used for the clean metal surface.
China produces at present and the metal cleaner of use contains chemical ingredientss such as strong acid, highly basic, phosphoric acid salt and aluminium salt mostly, these products are toxic to human body, the microbiological deterioration performance is poor, and grievous injury animals and plants, foam is many, polluted river water and groundwater resource can produce in various degree damage to the metallic surface that is cleaned simultaneously.
At the problems referred to above, a kind of efficient, low bubble, antirust, the free of contamination metal cleaner of providing of the present invention.
The present invention is a composition, and it forms (weight percentage) by following prescription:
Alkylphenol-polyethenoxy (10) ether 1～5%
Dodecyl diglycollic amide 1～5%
Polyoxyethylene aliphatic alcohol ether 1.5～5%
Polyethers 2,020 1～5%
Sodium Nitrite 5～10%
Trolamine 5～10%
All the other are water.
The present invention preferably fill a prescription (weight percentage) be:
Alkylphenol-polyethenoxy (10) ether 2～5%
Dodecyl diglycollic amide 1～3%
Polyoxyethylene aliphatic alcohol ether 1.5～3%
Polyethers 2,020 2～5%
Sodium Nitrite 5～8%
Trolamine 7～10%
All the other are water.
In order to reach the rot-resistant purpose, can also in prescription, add the Sodium Benzoate of 1～10% (weight percentage).
Composition of the present invention only needs each component in the prescription is mixed, and stirring gets final product.
The present invention has low bubble, efficient (cleaning rate is more than 90%), the metallic surface is not had the advantage of corrosion (rust-preventing characteristic reaches 0 grade), good stability, pollution-free (without phosphorus and aluminium).
Further specify the present invention below in conjunction with embodiment.
Embodiment 1～2:
Each component of different ratios is obtained metal cleaner according to mixing shown in the table 1, measure its cleaning rate, pH value, rust-preventing characteristic and stability respectively.Wherein,
Cleaning rate: the greasy dirt weight/greasy dirt original weight of cleaning rate=wash.
PH value: directly measure mixed composition with the wide pH value test paper.
Rust-preventing characteristic: grading standard: 0 grade of surface is rustless, no considerable change.
1 grade of surface is rustless, light discolouration or loss of gloss.
2 grades of light rust in surface or inhomogeneous variable color.
3 grades of surperficial big area corrosions.
Stability: mixed composition was placed after 4 hours, observed its layering situation, and is stable
For not stratified not muddy, shakiness is decided to be layering or muddiness.
Comparative Examples 1～2:
Increase traditional triethanolamine oleate in prescription, and do not use polyethers 2020 or trolamine, measure after the same method, every performance index see Table 1, as a result poor effect.
