Description
Technical Field
The invention relates to the field of metal rust prevention, and in particular relates to cucurbituril modified organosilicon metal rust preventing water and a preparation method and application thereof.
Background
The emergence and rapid development of metal materials have promoted the continuous progress of the human civilization society. The corrosion phenomenon of the metal material often occurs in the practical application process, and the corrosion of the metal can cause the change of the mechanical property, the electrical property and other properties of the material on one hand, so that the service life of the metal is greatly shortened; on the other hand, corrosion of metals is accompanied by a great economic loss. Therefore, the exploration and development of the environment-friendly and efficient metal rust prevention technology have great practical application value.
The main reason for metal corrosion is that at the interface of the metal, the metal is in contact with oxygen, water, etc. and further undergoes chemical or electrochemical reaction, resulting in the conversion of the elemental metal to the oxidized state. The main principle of the mode of slowing down metal corrosion is to isolate the contact of metal with oxygen and water, the isolation mode is mainly divided into passivation, alloying, coating application and the like, and the coating application in the practical application process is the most common mode.
The traditional metal surface rust prevention treatment is mainly a chemical conversion film method, such as a phosphating process, a ceramization process and the like, but the technologies have some remarkable defects. A large amount of phosphorus-containing wastewater and other pollution sources such as heavy metals and other harmful substances can be generated in the phosphating process, so that the application of the phosphating process is greatly limited. Compared with the phosphating process, the vitrification process can form a more compact zirconium dioxide film layer, but has obvious film forming defects and needs an additional process for secondary treatment.
The silanization treatment of metal surface is a new type of rust-proof technology. Compared with the high pollution of the phosphating process and the complexity of the vitrification process, the silanization technology represents a novel and environment-friendly technical route. The core principle of the silanization rust prevention technology is that a large number of silanol bonds (Si-OH) are formed by utilizing the hydrolysis of organic silane in water, the high-activity silanol bonds and Metal-OH on the surface of Metal are subjected to dehydration reaction to form a large number of Si-O-Metal bonds, and in addition, the silanol bonds and the silanol bonds can be dehydrated and condensed to form Si-O-Si bonds. Thus, a network-like silane film structure is formed on the metal surface. In addition, the R group connected with Si in the organic silicon has strong modifiability, can be coupled with a film-forming substance (resin) in the coating, and is beneficial to the coating of the subsequent coating.
The biggest problems encountered in practical application processes of processes based on silicone rust prevention are represented in three aspects: 1) Organosilicon molecules are easy to hydrolyze and polymerize, and the stability is poor; 2) The pure silane film has gap defects; 3) The film forming time of the silane film is longer. Therefore, how to solve the storage stability of organosilane, shorten the film forming time and fill up the film forming defects is the key for promoting the development of the novel metal rust prevention technology.

And then diluting the prepared cucurbituril modified organosilicon metal rust-preventive water by 500 times with water, and controlling the pH value to be 4-4.5 by using phosphoric acid or sodium acetate. Soaking the prepared cold-rolled sheet in diluted antirust water for 1-2 min, taking out, washing with water for 2-3 times, and oven drying.
And (3) performance testing:
