Organosilicon fluorine material for sealing and protecting irony cultural relics and method of producing the same

Abstract

The invention discloses an organic fluosilicic material used for sealing and protecting an iron cultural relic; the main components of the organic fluosilicic material consists of a main agent, a flatting silica and a thinner; wherein, the component of the main agent is an organic fluosilicic polymer; and the organic fluosilicic polymer is prepared by the hydrolytic polycondensation reaction of an organic silicon mixed monomer and hydroxy fluosilicic oil under the existence of an acid catalyst. The invention also discloses a preparation method of the organic fluosilicic material used for sealing and protecting the iron cultural relic. Test shows that after the organic fluosilicic material is adopted for carrying out sealing and protection on the surface of the iron cultural relic, protections of colorless, transparency, lightless and maintaining the original appearance on the iron cultural relic are realized; the corrosion resistance and the aging resistance are very good; moreover, the organic fluosilicic material has better self-cleaning performance. Not only can the problem of changing the original appearance of the cultural relic commonly existed in iron cultural relic sealing and protecting materials be solved, but also the corrosion resistance and the weatherability can be greatly improved.

Description

technical field [0001] The invention relates to a silicon-fluorine material used for the anti-corrosion protection of outdoor or stored iron cultural relics, and also relates to a preparation method of the silicon-fluorine material used for the anti-corrosion protection of outdoor or stored iron cultural relics. Background technique [0002] Because the chemical properties of iron are more active than metals such as gold, silver, and copper, and their chemical stability is poor, iron cultural relics are more likely to corrode. From the analysis of the cause of corrosion, the electrochemical corrosion with the participation of oxygen and water mainly occurred on iron cultural relics. In order to avoid electrochemical corrosion reactions, oxygen and water should be isolated as much as possible, and it should be protected in the best environment without corrosion conditions. Thereby improving the corrosion resistance of iron cultural relics. Therefore, after cleaning, rust rem...

AI Technical Summary

Problems solved by technology

[0003] The earliest sealing material for iron cultural relics is paraffin wax, which has a certain sealing effect, but has the characteristics of poor temperature resistance, unstable film-forming state, and greasy feeling on the surface.

With the development of chemical science and technology, people gradually use synthetic resin as the matrix as the sealing agent. At present, the widely used sealing materials include polyacrylic resin, polyurethane resin, silicone resin, silicone acrylic resin, etc. Although these resins are widely used, It also has a certain protective effect on iron cultural relics, but they have some performance defects in aging resistance, waterproof and antifouling, glare, permeability, reprocessing, adhesion, etc., and it is difficult to achieve both the improvement of iron cultural relics Excellent anti-corrosion performance and aging resistance, and in line with the principle of "colorless, transparent, no glare, keeping the original appearance of cultural relics, and reprocessing" for the protection of cultural relics

[0004] At present, there are few domestic and foreign research reports on the use of hydrophobic sealing materials for iron cultural relics. It is generally required that the sealing materials for iron cultural relics should not only have the function of hydrophobic and antifouling, but also meet the requirements of the relevant principles in the "Cultural Relics Protection Law". Performance: reprocessability; basic transparency, no glare; good aging resistance; good anti-corrosion performance; high tear resistance; expansion coefficient as close as possible to metal, etc.
