Abstract
The invention relates to the technology of anticorrosion additives and aims at providing an application method of a low-cost corrosion inhibitor loading structure. The method comprises the following steps: adding 10 mass parts of kieselguhr loading corrosion inhibitor into 100 mass parts of water-based paint; mixing and stirring for 3 hours; and coating the anti-corrosion coating part. In the invention, by adopting natural mineral kieselguhr as a porous loading structure, direct contact between the corrosion inhibitor and the paint is avoided, and the content of the corrosion inhibitor can be increased by about 3%. The loading matrix in the low-cost corrosion inhibitor loading structure is kieselguhr which is a natural mineral and has relatively good pore structure distribution and is very suitable to be directly used as a loading structure, and a complicated preparation process of a porous loading structure is avoided. Since the kieselguhr is cheap, the raw material cost of the loading structure is remarkably reduced, and the loading structure is suitable for industrial large-scale application and promotion.
Description
Technical field
The present invention relates to anticorrosive additive technology of preparing, particularly to the using method for low cost corrosion inhibiter support structures.
Background technology
The decay resistance of coating is required significantly high by boats and ships anticorrosive paint especially shell anticorrosive paint; the corrosion-inhibiting coatings such as common organic resin coordinate pretreatment layer, priming paint; it is simultaneously introduced the anodic protection agent such as zinc powder, there is good decay resistance in certain thickness situation.But it is strong that organic water-repellent preservation is coated with layer absorbent, can produce Swelling so that it is decline for the shielding action of corrosive medium after certain life cycle, therefore need in use for some time to repair and be heavily coated with to ensure the properly functioning of boats and ships.So that corrosion inhibitor assists to improve the decay resistance of coating, but directly corrosion inhibitor is joined in coating or coating and easily run off, need a kind of support structures it wherein just can be prevented to run off corrosion inhibitor cladding, on the other hand, make corrosion inhibitor be dispersed in coating or coating, then need corrosion inhibitor support structures to have good dispersibility in coating or coating.
At present, conventionally used porous support structures is porous silica microsphere or poriferous titanium dioxide, and these material preparation process are more complicated, it is necessary to multiple times of filtration, dry, and technological requirement is high, and production efficiency is relatively low, thus, relatively costly.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, it is provided that the using method of a kind of low cost corrosion inhibiter support structures.
For solving technical problem, the solution of the present invention is:
Thering is provided the using method of a kind of low cost corrosion inhibiter support structures, be added to the water paint of 100 mass parts by the tripolite loading inhibitor structure of 10 mass parts, mix and blend is after 3 hours, for the coating for anticorrosive coating position；
The concrete preparation process of described low cost corrosion inhibiter support structures includes:
(1) under the stirring condition of 200r/min, 100 mass parts water add the hydrochloric acid conditioning solution pH value of 0.1 mol/L between 3～5；Then solution is heated to 50 DEG C, adds 10～15 mass parts cerous nitrate mix homogeneously, add 1 mass parts absolute ethyl alcohol and stirring 0.5 hour；
(2) 10 mass parts analytical pure kieselguhr are joined in the solution of step (1) under 500r/min stirring condition, mix and blend 3 hours；
(3) by the mixture centrifugation of step (2) gained, with after washing with alcohol 4 times after 80 DEG C of oven dryings, take out ground 200 mesh sieves, obtain low cost corrosion inhibiter support structures.
In the present invention, described kieselguhr is analytical pure, and fineness is 1-3mm.
In the present invention, described cerous nitrate is CeNO3·6H2O, analytical pure.
Inventive principle describes:
Corrosion inhibiter (cerous nitrate) can constantly consume in coating antiseptic erosion process, thus the amount of corrosion inhibiter determines the corrosion-resistant cycle of coating.In general coating antiseptic technology, corrosion inhibiter is directly added in coating.But the amount of corrosion inhibiter can not add too much, because corrosion inhibiter ion concentration is high, and can generating electrodes reaction.If the excessive stability that will affect coating of addition, be typically in anticorrosive paint add amount in 0.001mol/L concentration range (about about one thousandth).
Adopt loose structure load corrosion inhibiter that too much corrosion inhibiter can be avoided to add the impact of the stability on coating, but porous support structures is (such as porous silica microsphere, TiO 2 porous microspheres) complicated process of preparation, technological requirement be strict, and yield poorly, therefore price is higher.Kieselguhr is the silicon ore of a kind of loose structure, it is distributed widely in China East China, the Northeast, cheap, the present invention prepares corrosion inhibiter support structures with natural porous mineral (kieselguhr) for raw material, significantly reduce cost, on this basis, it is to avoid corrosion inhibiter is directly and coating contacts and de-stabilising effect that coating is caused.
Compared with existing technology of preparing, the method have the advantages that
The present invention adopts natural minerals kieselguhr as porous support structures, it is to avoid corrosion inhibiter directly contacts with coating, the content of corrosion inhibiter can be increased to about 3 percent.
Load matrix in low cost corrosion inhibiter support structures prepared by the present invention is kieselguhr, is a kind of natural minerals, has good pore size distribution$, be well suited for using directly as support structures, it is to avoid the preparation process that porous support structures is complicated.Kieselguhr is cheap, thus significantly reduces the cost of raw material of support structures, is suitable for industrial using in a large number and promoting.
