Abstract

A kind of High efficient cast iron antirust water composition of the present invention, it is characterized in that, a kind of long period antirust of can reaching is provided, environment amenable cast iron antirust water composition, to achieve these goals, described High efficient cast iron antirust water composition is made up of sodium molybdate, borate, positive 11 carbon dicarboxylic acids, benzotriazole, antirust emulsified dose of multiamide, antirust emulsified dose of multiamide, p-tert-butyl benzoic acid, triethanolamine and water.

Description

A kind of High efficient cast iron antirust water composition

Technical field

The present invention relates to waterborne anti-rust field, espespecially a kind of High efficient cast iron antirust water composition.

Background technology

With industrial expansion, the species and kind of Cast Iron Products are more and more, China's ferrous metal rust prevention during manufacture and Cast-iron blank part interim stock antirust is mainly by the way of antirust oil, antirust paint and protection by spraying aqueous preventives water is applied.

Apply antirust oil cost high, easy cleaning, is not easy to the processing of subsequent handling；Apply antirust paint cost also high, and Carry out after parts assembling, with the operation of machinery, antirust paint is peeled off, and causes secondary pollution；Aqueous rust preventive containing nitrite There is good anti-rust action to metal, but nitrite is irritant to human body, is also gradually disabled rust-inhibiting additive, Existing cast iron aqueous rust preventive, also in the presence of certain defect, does not often reach requirement in antirust time and performance.

The content of the invention

A kind of High efficient cast iron antirust water composition of the present invention, it is characterised in that overcoming the deficiency of above-mentioned technology, there is provided one kind Long period antirust, environment amenable cast iron antirust water composition can be reached.

To achieve these goals, case is put in technology of the invention solution is：Described High efficient cast iron antirust water composition is By sodium molybdate, borate, positive 11 carbon dicarboxylic acids, benzotriazole, antirust emulsified dose of multiamide, antirust emulsified dose of multiamide, right P t butylbenzoic acid, triethanolamine and water composition, each component and its weight/mass percentage composition are：

Sodium molybdate 6~12%

Borate 6~15%

Positive 11 carbon dicarboxylic acids 2~6%

Benzotriazole 0.2~1%

Antirust emulsified dose 2~3% of multiamide

P-tert-butyl benzoic acid 0.5~2%

Triethanolamine 1~10%

Water surplus

Described borate, is a kind of boric acid diethanol amine ester, with antirust and bacteriostasis.

Antirust emulsified dose of described multiamide, is a kind of oleoyl multiamide compound N EUF184, with good antirust Property and emulsifying dispersivity.
