Abstract
The present invention provides a sort of synergistic corrosion inhibition paint of which the air corrosion resistant capability increases by numbers of times, and belongs to the synergistic corrosion inhibition paint especially suitable for the surface protection of steel. The present invention is characterized in that during the production process of prior paint, a corrosion inhibitor NO. 1 of cyclohexyldiamine oleate or a corrosion inhibitor NO. 2 of tributyl amine caprate is applied to paint for a bottom layer and a face layer, wherein the addition amount of the corrosion inhibitor accounts for 0.1 to 3% of total weight, and the corrosion inhibitor is added into the paint through an additive of dimethylbenzene. After the paint is used by cooperation, the air corrosion resistant capability can be improved by 4 to 10 times.
Description
A kind of weather-resistant synergistic complexing slow corrosion coating is specially adapted to the synergistic complexing slow corrosion coating that steel surface is protected.
At present, widely-used weather-resistant coating such as alkydpaints (C such as agricultural machine, engineering machinery, heavy-duty machinery, textile manufacturing machine, building machinery
06-1C
06-2), etc. constitute the typical combination coating since above-mentioned coating easily factor such as foaming cause the corrosion of steel surface.People expect to improve the heat resistance ability of this class coating for a long time.At present, in order to address the above problem, solve these problems by means of rust-stabilising pigment and improvement macromolecule filming material two aspects mostly.But do not obtain the weather-resistant effect of ideal up to now as yet.Prove by retrieval, the Soviet Union, West Germany, Japan and the U.S. have all successively carried out the discussion work of inhibiter in the coating at present, but all do not solve the stability of coating, all apply inhibiter in particularly do not see the bottom coating and the investment precoat and produce the report of synergistic effect.
It is easy to the objective of the invention is to obtain a kind of preparation method, do not change existing coating synthesis technique, physics, mechanical property and the homogeneous that the coating that can keep former coating to form has, synergistic complexing slow corrosion coating stable and that can increase substantially its weather-resistance.
The present invention realizes like this, promptly in priming paint and investment precoat, all apply a kind of organic inhibitor, prepare a kind of novel corrosion inhibition coating, be used with this inhibition priming paint and inhibition investment precoat and can produce the synergism inhibition effect, make it to form the synergism corrosion inhibiting coating that a kind of weather-resistance is doubled and redoubled.The inhibiter that synergistic complexing slow corrosion coating of the present invention applies in priming paint and investment precoat, its best inhibiter have No. 1 inhibiter or No. 2 inhibiter.No. 1 inhibiter is by oleic acid-C

3N synthetic capric acid Tributylamine, inhibiter is added in the coating by additives dimethylbenzene and goes.
It is additives that additives dimethylbenzene adds optimum value: inhibiter=1: 100.The optimum value of the add-on of inhibiter is an inhibiter: coating=0.1~3: 99.9~97.
Synergistic complexing slow corrosion coating of the present invention.It is simple to have preparation, do not change the advantage of former coating producing process, under the condition of the physics that guarantees former coating, mechanical property, this priming paint and investment precoat are used and improve 4~10 times of weather-resistance, and salt fog resistance and resistance of aging also increase simultaneously.This synergistic complexing slow corrosion coating homogeneous, stable can reduce cost 1% for coating material production factory, only by about 10,000 tons of the annual 10%(that produces the alkyd paint total amount of China) promote the use of synergistic complexing slow corrosion coating calculating, can obtain the Spring Festival holidays to prop up economic benefit more than 10,000,000 yuan.Because the thickness of synergism corrosion inhibiting coating has been reduced to 40 microns effects that just can improve 4 times of weather-resistance from original 50 microns, so can save 1/5 coating to the user, this economic benefit is sizable.Simultaneously this synergism corrosion inhibiting coating weather-resistance is minimum to increase by 4 times, and the quality that has not only improved this class coating has enlarged its range of application, and can't estimate for the social benefit that produced work-ing life and the economic benefit of prolonged mechanical product.
Embodiments of the invention are the example explanation with No. 1 corrosion inhibition coating:
1. preparation inhibiter: the oleic acid and the dicyclohexyl amine of gram molecular weight such as use to synthesize, its reaction equation is:
Evenly be stirred to react completely till, form the oleic acid dicyclohexylamine inhibiter.
2. system synergistic complexing slow corrosion coating:
The proportioning of additives dimethylbenzene by 1: 100 joined in the above-mentioned inhibiter that makes, stir, inject priming paint or investment precoat then, it is benefit that its inhibiter accounts for 0.1%~3% of gross weight, carries out vigorous stirring and makes it to become till the equal one.
The storage of the above-mentioned corrosion inhibition coating for preparing, transportation, using method are all identical with former coating.
Prepare the method for synergistic complexing slow corrosion coating with example 1 with No. 2 inhibiter.
