Abstract

The invention discloses a water-soluble anti-rusting agent and belongs to the technical field of rust prevention of metal. The water-soluble anti-rusting agent comprises, by weight, 3%-8% of molybdate, 10%-20% of sebacic acid, 5%-15% of triethylamine, 6%-13% of boric acid, 4%-8% of oleic alkanolamide, 2%-7% of dodecanedioic acid, 6%-10% of polyepoxysuccinic acid and the balance water. The water-soluble anti-rusting agent does not contain the elements, such as sulfur and phosphorus, which are harmful to the environment or the extremely toxic substances such as chromium salt and nitrite, and the excellent anti-rusting performance which is the same as that of a traditional anti-rusting agent or even better is achieved; in addition, liquid waste treatment is not complicated any more, and the water-soluble anti-rusting agent is environment-friendly anti-rusting liquid.

Description

A kind of water soluble anti-rust agent
Technical field
The invention belongs to metal rust preventing technical field, particularly relate to a kind of water soluble anti-rust agent.
Background technology
Metal in an atmosphere, can and oxygen, water and other impurity there is chemical action or electrochemical action under certain condition and produce metallic corrosion.Particularly be in the metallic substance between metalworking procedures, because surfactivity is high, workpiece in processing, carrying, checking, air, hand perspiration and contact with the obnoxious flavour in air through moisture, make workpiece be easy to produce corrosion, cause finished work to scrap or do over again.In order to prevent metal works corrosion between the shelf lives, antirust treatment must be carried out.Present antirust treatment great majority are the modes of adding rust-preventive agent, and rust-preventive agent has generally included slushing oil and Water-soluble antirust liquid.
Antirust main body of oil is mineral oil, although it can obtain certain rust-proof effect, easily volatilize, pungent taste is heavier, for long-term be that impact is healthy the operator of shopwork, but also can to environment.Water soluble anti-rust agent is as the term suggests be one water-soluble antirust liquid under certain condition, it is not based on oil, composition is also uncomplicated, but only there is the rust-proof effect of short-term, and some chromic salts, nitrite etc. of adopting have the one-tenth of highly toxic substance to be grouped into more, therefore also run counter to for the environmental protection theory advocated now.
Summary of the invention
The object of the invention is the water soluble anti-rust agent that a kind of green is provided for the defect existing for existing water soluble anti-rust agent, this rust-preventive agent is not containing environmentally harmful sulphur, phosphoric, also not containing the highly toxic substance such as chromic salts, nitrite, and the rustless property obtaining traditional rust-preventive agent excellence is even better, be a kind of environment amenable antirust liquid.
The object of the invention is to realize by the following technical solutions:
A kind of water soluble anti-rust agent, comprise following component by weight percentage: molybdate 3 ~ 8wt%, SA 10 ~ 20wt%, triethylamine 5 ~ 15wt%, boric acid 6 ~ 13wt%, oleic acid alkylolamide 4 ~ 8wt%, SL-AH 2 ~ 7wt%, poly-epoxy succinic acid 6 ~ 10wt%, surplus is water.
As further scheme, described water soluble anti-rust agent, comprise following component by weight percentage: molybdate 4 ~ 6wt%, SA 13 ~ 18wt%, triethylamine 7 ~ 12wt%, boric acid 7 ~ 10wt%, oleic acid alkylolamide 5 ~ 7wt%, SL-AH 3 ~ 5wt%, poly-epoxy succinic acid 7 ~ 9wt%, surplus is water.
As further scheme, described water soluble anti-rust agent, comprises following component by weight percentage: molybdate 5wt%, SA 15wt%, triethylamine 10wt%, boric acid 8wt%, oleic acid alkylolamide 6wt%, SL-AH 4wt%, poly-epoxy succinic acid 8wt%, surplus is water.
As further scheme, described molybdate is Sodium orthomolybdate and/or ammonium molybdate.
As further scheme, when molybdate adopts Sodium orthomolybdate and ammonium molybdate, the two mixes with the weight ratio of 1:1.
Owing to have employed technique scheme, the present invention has the following advantages:
Water soluble anti-rust agent of the present invention is not containing environmentally harmful sulphur, phosphoric, also the material not containing the severe toxicity such as chromic salts, nitrite, and the rustless property obtaining traditional rust-preventive agent excellence is even better, rust-proof life is longer, more stable, and liquid waste disposal is no longer complicated, be a kind of environment amenable antirust liquid.
Embodiment
The technique means realized to make the present invention, creation characteristic, reach object and effect clearly and be easy to understand, below in conjunction with embodiment, the present invention is further elaborated:
The invention provides a kind of water soluble anti-rust agent, comprise following component by weight percentage: molybdate 3 ~ 8wt%, SA 10 ~ 20wt%, triethylamine 5 ~ 15wt%, boric acid 6 ~ 13wt%, oleic acid alkylolamide 4 ~ 8wt%, SL-AH 2 ~ 7wt%, 6 ~ 10wt%, surplus is water.
Wherein, molybdate can form passive film in metallic surface, is rust-preventive agent composition of good performance, and does not almost have toxicity and the hazardness to environment.SA, as inorganic inhibitor, have the effect similar with molybdate, but cost is lower for molybdate.The compositions such as triethylamine, boric acid, oleic acid alkylolamide, SL-AH, poly-epoxy succinic acid are added on the basis of molybdate and SA again, obtain the rustless property of superposition, boric acid has preservative property simultaneously, and rust-preventive agent can be made after being added to rust-preventive agent to have antiseptic property.
