Abstract
The invention discloses a water-based long-effective antirust agent, which comprises the following parts: 5.0-30.0% C8-C10 carboxylate (sodium, potassium or ammonium salt), 5.0-15.0% ethanolamine (monoethanolamine, diethanolamine or triethanolamine), 3.0-8.0% boric acid (boric acid or ammonium borate) and 0.0-5.0% polyethylene glycol (8-10 polymerization degrees). The product displays light yellow transparent viscous liquid to dissolve in the water under normal temperature or heating condition, which possesses excellent protective effect for common carbon steel and cast iron.
Description
Technical field:
What the present invention relates to is the chemically treated field on metallic substance (iron and iron alloy) surface.
Background technology:
Current antirust processing to metallic substance (particularly to 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, such rust-preventive agent has a lot of drawbacks: the one, and this class rust-preventive agent has very big toxicity, and nitrite is very strong carcinogenic substance, to human body, to environment, very big harm is arranged all.In addition,, form day shift after the use easily in the metallic surface, influence outward appearance owing to be the alkali material; Very sensitive to soda acid, also must pay close attention to the effective concentration of the working fluid that uses, otherwise will play the opposite effect.Not only do not play rust inhibition, also can play corrosive nature, be called as " dangerous type " rust-preventive agent.And to the common poor effect of cast iron.Be difficult to satisfy processing requirement.The substitute that a lot of these series products also occurred is at present compared with nitrite but rust-proof life is generally very difficult, is generally used for rust prevention during manufacture.The non-nitrous salt water-based antirust that CN1530463 (application number 03111171) provides, though broken away from nitrite, but with compound method complicated (divide A, B two components, three heating are fused, reacted), also there are many inconvenience in actual the use more than the raw material variety of its use.
Summary of the invention:
At the deficiency that prior art exists, the present invention aims to provide a kind of without nitrite, pollution-free, long-acting metal antirusting agent that preparation is simple, effective.
The technical solution used in the present invention is: form with composite systems such as organic carboxylate, borate, thanomin and polyoxyethylene glycol.Raw material variety that it is used and proportioning (W%) are
C8～C10 carboxylate salt 5.0～30.0
Thanomin 5.0～15.0
Boric acid class 3.0～8.0
Polyoxyethylene glycol 0.0～5.0
Water 42.0～87.0
Wherein: the carboxylate salt of C8～C10 is its sylvite, sodium salt or ammonium salt, and is better with sodium salt; Thanomin is in Monoethanolamine MEA BASF, diethanolamine, the trolamine 1～2 kind; The boric acid class is boric acid or ammonium borate, is advisable with boric acid; Polyoxyethylene glycol is 8～10 ethylene glycol polymerizations.Practice it seems that below prescription is better:
C8～C10 carboxylate salt 8.0～15.0
Trolamine 3.0～14.0
Boric acid 3.0～6.0
Polyoxyethylene glycol 0.0～5.0
Water 60.0～85.0
The preparation of rust-preventive agent is very simple, and 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, rust-preventive agent of the present invention all has the favorable protection effect to general carbon steel, cast iron.Can do not formed hickie, no current mark by the anti-rust metal surface, keep the original color and luster in metallic surface, all above no changes of humid heat test cycles 4.In addition, stability of solution of the present invention is good, 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.
