Organic compound paint crosslinking agent
According to the relevant information, glyoxal, ethylene glycol diacetate can dissociate the organic acid in the water glass and make the sodium silicate.
In recent years, organic coupling agents and complexing agents have been increasing. These organics have strong complexability, which can have a good fixed effect on Na + in water glass. The cross-linking technology in this area is under development.
When there is a trace of water, the pigment will dissociate from the coating to the ions with the inhibition function, and the electrode polarization of the corroded battery can be controlled by various mechanisms.
Electrochemical protection through some potential than the base metal is added in the coating and lively as filler metal, when electrolyte infiltration coating to metal substrate, the metal substrate with electronegativity filler metal corrosion cell formation, packing as anode dissolve occurs first, to protect the role of matrix, this kind of coating called sacrifice type coating [9]. Zinc powder, such as zinc rich in anticorrosion paint, ACTS as a sacrificial anode.
Chen hao et al. introduced the application of RTV antifouling paint on the wire and obtained the good effect of reducing or preventing the ice. The technology is available for reference.
The transmission line ice disaster and its prevention have become an urgent problem. The ice coating product use is extremely widespread, it can he applied to transmission lines, the tower pole, insulator and related metal fixed pieces, become fundamentally ease and the best measures to improve transmission lines ice conditions.
The research work of this field should be concentrated in the following aspects: the preparation method of the new superhydrophobic coating; To improve the mechanical strength of the coating to meet the needs of practical application; The study of the surface properties of such coatings should be considered in addition to hydrophobic properties, and other properties should be considered as well as more theoretical basis for their application.
Such as construction, transportation, petrochemical, electric power industry, the development of anti-corrosion coatings market scale is second only to architectural coatings and in the second place, these areas of the varieties and properties of anticorrosive coatings put forward higher requirements.
Chinese name: Diethyl toluene diamine(DETDA)

Because the water-based polyurethane anticorrosion coating has the advantage of environmental protection, some performance to achieve the performance level of the solvent-based polyurethane coatings, especially the waterborne two-component polyurethane coating has a broad application prospect in the field of anti-corrosion.
But water-based polyurethane anti-corrosion coating has some problems, such as poor water resistance and higher cost, which limits its application. Predictably with the increasingly attention of environmental protection laws and regulations and national scientific research workers of the continuous efforts, the development and application of waterborne polyurethane anticorrosion coating will bring a revolution in the field of corrosion protection.
With different molecular weight of epoxy compound preparation of fibroin membrane as crosslinking agent, this paper discusses the molecular weight of epoxy compound and epoxy compound additives, the dosage of catalyst on the influence of the main physical and chemical properties of sf membranes. The results show that the epoxy compounds of fibroin have apparent crosslinking effect, using large molecular weight epoxy compounds as crosslinking agent, of fibroin membrane while maintaining low hot water soluble loss rate at the same time, to achieve high elongation.
K. CHINO and c. WU studied supermolecule crosslinking and used the coordination bond of ammonia triacetic acid (ATA) and ethylene propylene rubber or copper sulfate and NBR.
Thermo-reversible hydrogen bonding (thc-epm) can be compared with thermoplastic vulcanized rubber (TPV), but it is different from the EPDM (s-epdm) rubber which is different from sulphur vulcanization.
Pure copper sulphate - NBR is better than pure sulphur vulcanized NBR (s-nbr), but no carbon-black enhanced s-nbr is good. Both have environmental advantages and economic advantages, easy to recycle.
