Abstract
The invention relates to a long-acting water-based metal rust inhibitor which consists of phytic acid, ethanolamine, boric class and acid amide; the raw material is non-toxic, harmless, and does not pollute environment; and the rust inhibitor is characterized by long antirust cycle, good stability, no delamination, and no precipitation.
Description
Technical field
The present invention relates to the antirust chemical treatment field of metal material surface.
Background technology
Current antirust processing to metallic substance (particularly iron and steel) surface, the water-based antirust that uses forms as host is composite with nitrite in a large number.Though its favorable rust preventing effect, cheap also is restricted for many years gradually: mainly be that this class rust-preventive agent has very big toxicity, nitrite is very strong carcinogenic substance, to human body, to environment, very big harm is arranged all.In addition, for the precision optical machinery product, because inorganic salt are in the metallic surface; Particularly there is the crystalline possibility at the place, slit, influences the degree of cleaning of product.
Summary of the invention
At the deficiency that prior art exists, the present invention aims to provide a kind of without nitrite, pollution-free, water-based long-acting metal antirusting agent that preparation is simple, effective.
The technical solution used in the present invention is: phytic acid, borax, thanomin and polyacrylamide etc. are composite and make.Raw material variety that it is used and proportioning (W%) are:
Phytic acid 2.0～4.0
Thanomin 4.0～16.0
Borax class 4.0～9.0
Polyacrylamide 1.0～6.0
Water 65.0～89.0
Wherein thanomin is any one or any two kinds of combinations in Monoethanolamine MEA BASF, diethanolamine, the trolamine; The borax class is boric acid or ammonium borate; Polyacrylamide is 7～9 ethylene glycol polymerization degree.
The process for preparation of rust-preventive agent: normal temperature or heat makes that raw material is soluble in water to get final product.Product is a light yellow viscous liquid.
Compared with prior art, the rust-preventive agent of wood invention all has the favorable protection effect to general carbon steel, cast iron, all above no changes of humid heat test cycles 5.In addition, rust-preventive agent good stability of the present invention can both keep stable under conditions such as high temperature and low temperature, not stratified, nothing precipitation.Product and materials safety,, environmentally safe harmless to human body when preparation and use is a kind of environmental protection, free of contamination long-acting metal antirusting agent.
Below the present invention is further illustrated with practical example:
Embodiment

Example 2
Phytic acid 9.0
Trolamine 13.0
Borax 5.0
Water 73.0
Prepare the same example.Product is a light yellow viscous liquid.Place 35～50 ℃ following 3 months, not stratified, do not have a precipitation.Carbon sheet is carried out antirust processing back keep the original color and luster in metallic surface, all no changes of humid heat test cycles 5.
Example 3
(W%) carries out the preparation of rust-preventive agent by following prescription:
Phytic acid 9.0
Trolamine 5.0

Borax 4.5
Water 76.5
Prepare the same example.Product is a light yellow viscous liquid.Place 35～50 ℃ following 4 months, not stratified, do not have a precipitation.Carbon sheet is carried out antirust processing back keep the original color and luster in metallic surface, all no changes of humid heat test cycles 5.
Example 4
(W%) carries out the preparation of rust-preventive agent by following prescription:
Phytic acid 12.0
Trolamine 13.0
Borax 8.0
Polyacrylamide 2.0
Water 65.0
Prepare the same example.Product is a light yellow viscous liquid.Place 25～35 ℃ following 5 months, not stratified, do not have a precipitation.Carbon sheet is carried out antirust processing back keep the original color and luster in metallic surface, all no changes of humid heat test cycles 5.
