Abstract
The invention discloses an environment-friendly metal corrosion-resistant treatment liquid and a preparation method thereof, wherein the environment-friendly metal corrosion-resistant treatment liquid comprises the following raw materials in parts by weight: 20-60 parts of ethanol, 100-300 parts of water, 3-8 parts of ethyl orthosilicate, 10-30 parts of vinyl tri (2-methoxyethoxy) silane, 0.05-0.5 part of mineral powder, 0.5-5 parts of ionic liquid, 0.5-5 parts of metal salt and 0.5-5 parts of ferric ammonium oxalate. The environment-friendly metal corrosion-resistant treatment solution disclosed by the invention can effectively improve the compactness and hardness of a film formed on the metal surface after the metal surface is pretreated, so that the corrosion resistance and the wear resistance of the metal surface are further improved.
Description
Technical Field
The invention relates to a metal treatment liquid and a preparation method thereof, in particular to an environment-friendly metal corrosion-resistant treatment liquid and a preparation method thereof.
Background
The metal material is the most widely used engineering material in modern society and plays an important role in the civilization and development of human beings. People not only use metal materials in the aspects of industrial and agricultural production and scientific research, but also can see the metal materials everywhere in daily life, and the metal materials are not used anytime and anywhere. However, the metal material is liable to react with the surrounding medium, causing metal corrosion, and once the metal is corroded, its performance will be greatly reduced. If the metal parts on the equipment corrode, the equipment cannot work, and economic and other losses are brought to people. Corrosion protection of metals is therefore very important.
In the prior art, metal corrosion-resistant treatment liquid is usually adopted to pretreat metal, so that the corrosion resistance can be improved to a certain extent, but the metal corrosion-resistant treatment liquid is not very effective.
Disclosure of Invention
The invention provides an environment-friendly metal corrosion-resistant treatment solution and a preparation method thereof. In order to solve the problems, the invention adopts the following technical scheme:
the environment-friendly metal corrosion-resistant treatment solution is characterized by comprising the following raw materials in parts by weight:
20-60 parts of ethanol,
100 portions of 300 portions of water,
3-8 parts of ethyl orthosilicate,
10-30 parts of vinyl tri (2-methoxyethoxy) silane,
0.05-0.5 parts of mineral powder,
0.5-5 parts of ionic liquid,
0.5-5 parts of metal salt,
0.5-5 parts of ammonium ferric oxalate.
Preferably, the first and second liquid crystal materials are,
the mineral powder is talcum powder and/or attapulgite, and is preferably modified mineral powder. The modified mineral powder is attapulgite modified by tetrabutyl titanate modified talcum powder and/or tri-tert-butyl borate. The modified mineral powder is preferably a mixture of tetrabutyl titanate modified talcum powder and tri-tert-butyl borate modified attapulgite, and the mass ratio of the tetrabutyl titanate modified talcum powder to the tri-tert-butyl borate modified attapulgite is (1-3): (1-3).
The ionic liquid is preferably a pyridyl ionic liquid, is more preferably one of N-hexyl-4-methylpyridine tetrafluoroborate, N-butylpyridinium trifluoromethanesulfonate and N-butylpyridinium tetrafluoroborate, and is most preferably N-butylpyridinium trifluoromethanesulfonate. The ionic liquid can be adsorbed on the surface of the aluminum alloy, so that the corrosion-retarding effect is improved.
The metal salt is at least one of nickel nitrate, cerium nitrate and cobalt acetate, preferably, the metal salt is nickel nitrate, cerium nitrate and cobalt acetate according to the mass ratio of (1-2): (1-2): the mixture of (1-2). Most preferably, the metal salt is nickel nitrate, cerium nitrate and cobalt acetate in a mass ratio of 2: 1: 1. The metal salt can form an alloy layer on the surface of the aluminum alloy under the action of ferric ammonium oxalate, and the hardness and the density of the alloy layer are improved by adjusting the proportion of the three metal salts, so that the wear resistance and the corrosion resistance are improved.
