Abstract
The invention discloses an organic amine corrosion inhibition metal surface treatment agent which is composed of the following raw materials, by weight, 2-3 parts of glycerin, 4-6 parts of sericin, 0.8-1 part of polyacrylamide, 0.05-0.1 part of yttrium nitrate hexahydrate, 0.4-1 part of a silane coupling agent KH-550, 150-200 parts of water, 0.6-1 part of iminodiacetic acid, 0.3-0.4 part of propolis, 0.7-1 part of cocofatty acylamido propyl betaines, 0.2-0.3 part of polyimide and 1-2 parts of sodium metaborate. After hydrolysis of the added silane, an adsorption type film can be formed on metal surface so as to isolate water molecules and oxygen molecules in the environment, thus having a protective effect. With the addition of organic amine, a layer of adsorption film can be formed to prevent corrosive substances such as water, chloride ion and oxygen, etc. from contacting with metal, thus having an effect of preventing corrosion of metal.
Description
Technical field
The present invention relates generally to metal conditioner field, particularly relates to a kind of organic amine inhibition metal conditioner.
Background technology
Metal conditioner refers to the general name of chemical agent metallic surface being carried out to various process.Metal finishing includes oil removing, rust cleaning, phosphatization, the substrate pretreatment such as antirust, for metal coating techniques, metal protection technology are prepared, the use of substrate pretreatment quality to after this coating preparation and metal has a great impact, water soluble anti-rust agent wherein then may be dissolved in water and forms the aqueous solution, and metal can prevent rust corrosion after this aqueous solution process.Their rust inhibition can be divided three classes.
1. metal and rust-preventive agent generate the insoluble and sull of densification, thus prevent the anode dissolution of metal or promote the passivation of metal, thus suppressing corrosion of metal.This kind of rust-preventive agent is also called passivator, as Sodium Nitrite, potassium bichromate etc.In use, enough consumptions should be ensured.When using quantity not sufficient, can not form complete sull, on not covered very little metallic surface, corrosion electric current density increases, and easily causes severe local corrosion.2. metal and rust-preventive agent generate the salt of indissoluble, thus metal and corrosive medium are isolated, and avoid corrosion.Such as: the phosphoric acid salt had can generate insoluble phosphoric acid molysite with iron effect; Some silicate energy and iron, aluminium effect generate insoluble silicate etc.3. metal and rust-preventive agent generate the complex compound of insoluble, cover metallic surface and protect metal to avoid corrosion.Such as: benzotriazole and copper can generate inner complex Cu (C6H4N3) 2, be both water insolublely also insoluble to oil, thus can protect the surface of copper.
Summary of the invention
The object of the invention is just to provide a kind of organic amine inhibition metal conditioner.
The present invention is achieved by the following technical solutions:
A kind of organic amine inhibition metal conditioner, it is made up of the raw material of following weight parts:
Glycerine 2-3, silk gum 4-6, polyacrylamide 0.8-1, six water Yttrium trinitrate 0.05-0.1, silane resin acceptor kh-550 0.4-1, water 150-200, iminodiethanoic acid 0.6-1, propolis 0.3-0.4, AMONYL 380LC 0.7-1, polyimide 0.2-0.3, sodium metaborate 1-2.
A preparation method for organic amine inhibition metal conditioner, is characterized in that comprising the following steps:
(1) get silk gum, add the 50-60% of above-mentioned water weight, add silane resin acceptor kh-550, six water Yttrium trinitrates after stirring, 600-1000 rev/min of dispersed with stirring 10-20 minute, obtains silane liquid;
(2) by polyacrylamide, polyimide mixing, add glycerine after stirring, be heated to 60-70 DEG C, add above-mentioned silane liquid, insulated and stirred 20-30 minute at the temperature disclosed above, adds AMONYL 380LC, 700-1000 rev/min is stirred 5-7 minute, obtains silk gum emulsion;
(3) above-mentioned silk gum emulsion mixed with each raw material of residue, 800-1000 rev/min of dispersed with stirring 30-40 minute, obtains described metal conditioner.
Advantage of the present invention is:
The silane that the present invention adds can form adsorptive type rete in metallic surface after hydrolyzing thus water molecules in isolated environment and oxygen molecule play protective effect, the organic amine added can form one deck adsorption film, stop water, the corrosives such as chlorion and oxygen and metallic contact, play the effect preventing metallic corrosion, rare earth ion can corrode with metallic substrate surface generation oxygen uptake the OH-complexing produced and produce insoluble complex, this complex compound dehydration can form oxide precipitation to substrate surface further, the electrode reaction of slowing down corrosion, coordinate water-soluble silk glue, the stability forming film can be strengthened, improve antirust corrosion mitigating effect.
