Abstract
The invention discloses a cast iron water-based antirust agent which comprises the following components in parts by weight: 66.0 parts of water, 10.0 parts of triethanolamine, 8.0 parts of diamino aqueous amine, 4.0 parts of water-soluble silane coupling agent, 6.0 parts of potassium fluozirconate, 5.0 parts of ethylenediamine tetraacetic acid tetrasodium salt and 1.0 part of antibacterial preservative. The antirust agent is not adhered to dust, the surface of cast iron is clean, and the antirust agent is environment-friendly, harmless to operators, long in antirust time and high in safety.
Description
Technical field
The present invention relates to rust-preventive agent, relate in particular to the water-based antirust for cast iron.
Background technology
Water-based antirust agent is widely used in the antirust processing in metallic surface, the water-base metal rust protection liquid great majority that use at present all contain nitrate or nitrite, and contain a large amount of+b valency chromium, the elements such as phosphorus, zinc, nickel, these materials can change into carcinogens or have radioactivity, serious environment pollution is detrimental to health.And adopt slushing oil as rust-preventive agent, and oil belongs to inflammable explosive article, poor safety performance, and the antirust time is short, only is about one month in the natural situation; And have volatility, smell is large, during construction operator is had certain harm, not environmental protection; Be exposed to dust in the outer very easy absorbed air, affect attractive in appearancely, not easy to clean, its cost is higher, and is uneconomical, and Chang Yinwei does over again and scraps has directly increased cost.
Summary of the invention
The present invention is directed to the problems referred to above, research and develop a kind of water-base metal antirusting agent of asepsis environment-protecting, mainly for the antirust processing of cast iron.
Technical solution of the present invention is as follows: the cast iron water-based antirust is characterized in that: its moiety is by weight ratio:
66.0 parts in water,
10.0 parts of trolamines,
8.0 parts of diamine base water-based amine,
4.0 parts of soluble silane coupling agents,
6.0 parts of potassium fluozirconates,
5.0 parts of tetrasodium ethylenediamine tetraacetates,
1.0 parts of fungicidal preservatives.
Diamine base water-based amine, the soluble silane coupling agent, both bring into play rust inhibition, must have EDTA-four receive (tetrasodium ethylenediamine tetraacetate) play synergy, otherwise rustless property is very poor, the three is indispensable.Cast iron is loose porous, has formed the very thin and corrosion resistant film of one deck on its surface by sequestrant absorption (or with iron reaction), thereby has played antirust effect.
Advantage of the present invention is as follows:
The first, cast iron is difficult to phosphatization, and is antirust very difficult, and slushing oil commonly used is antirust, is easy to sticking ash and antirust time short, the not sticking dust of this rust-preventive agent, and Cast Iron Surface is very clean.
The second, do not contain+6 valency chromium and phosphorus, environmentally safe, to the operator without injury.
The 3rd, wastewater treatment is simple, but only need comprehensive up to standard after just draining.
The 4th, the antirust time is long, antirustly under the seasoning ventilation condition reaches half a year to one year.
The 5th, the aq. type treatment agent, not flammable, safe.
Description of drawings
Nothing.
Embodiment
The invention will be further described below in conjunction with specific embodiment.Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment: the cast iron water-based antirust, by tap water 66.0kg, trolamine 10.0kg, diamine base water-based amine 8.0kg, soluble silane coupling agent 4.0kg, potassium fluozirconate 6.0kg, EDTA-four sodium (tetrasodium ethylenediamine tetraacetate) 5.0kg, fungicidal preservative 1.0kg is configured.Wherein fungicidal preservative adopts the DM-623 fungicidal preservative of the Taiwan modest company of moral.
Cast iron is carried out antirust processing, at first cast iron is processed according to the sequential steps of oil removing, washing, acid pickling and rust removing, washing, then cast iron part was soaked 30 seconds ~ 60 seconds in this cast iron water-based antirust, rear taking-up seasoning gets final product, if better at 80 ℃ of-100 ℃ of condition drying effects.
Material of the present invention does not have combustibility and toxicity, uses safer, environmental protection, and the antirust time is long, has reduced the antirust maintenance cost of cast iron.
