Description
Technical Field
The invention relates to the technical field of chemical industry, in particular to a novel water-based antirust corrosion inhibitor capable of forming a dry film.
Background
The metal workpiece is easy to rust in the production, processing and transportation processes, so that a layer of film is required to be formed on the surface of the metal by using antirust oil, and chemicals for preventing the metal from rusting are required. The machine is difficult to operate and store without contact with oxygen, moisture or other corrosive media in the air, and these substances will electrochemically corrode and rust on the metal surface, and the prevention of corrosion should prevent the above substances from contacting the metal. The antirust belongs to one kind of antirust product, and other types of antirust oil, antirust paper and the like. The rust inhibitor is a super efficient synthetic penetrant, which can penetrate into rust, corrosive and oil stain strongly to remove rust and corrosive on screws and bolts easily, and has the properties of penetrating rust removal, loosening lubrication, corrosion resistance, metal protection and the like. And a lubricating film can be formed and stored on the surface of the component to inhibit corrosion by moisture and many other chemical components.
At present, the conventional antirust agent generally has certain technical defects. Wherein, the traditional rust preventive oil: the rust prevention period is long, and the medium-and-long-term rust prevention can be realized; but the surface of the workpiece is greasy, the surface cleanness is poor, and dust is easily polluted; on occasions needing cleaning and oil removing at the later stage, the oil removing difficulty is high, and the cleaning can be realized only by matching professional oil removing agents with a plurality of cleaning procedures. Conventional aqueous rust inhibitors: is beneficial to the later cleaning. There is still a greasy or white crystallization of the wet surface film. The antirust effect is weak. Phosphating and other film coating processes: short rust-proof period and dry surface, but changes the original color of the metal. Silane vitrified products: the antirust period is too short to meet the requirement of intermittent transfer between the working procedures, and the surface is dry, but the original color of the metal is changed.
Disclosure of Invention
The invention aims to provide a novel water-based antirust corrosion inhibitor capable of forming a dry film aiming at the technical defects of the prior art so as to solve the technical problem that the performance of the conventional antirust agent needs to be improved.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
a novel water-based antirust corrosion inhibitor capable of forming a dry film comprises the following components in percentage by weight: gamma-aminopropyltriethoxysilane: 35% to 46%, 2,4, 6-tris (aminocaproyl) -1,3, 5-triazine (triazine polycarboxylic acid): 8% -12%, triethanolamine: 1-3%, fatty alcohol-polyoxyethylene ether: 0.01 to 0.05 percent of fatty amine polyoxyethylene ether: 0.01% -0.05%, 6000 molecular weight polyethylene glycol: 0.01-0.05%, polyglycerol: 0.01-0.02%, alkynol defoaming agent: 0.01% -0.02%, pure water: and (4) the balance.
