Problems solved by technology

As a new type of anti-corrosion coating material, polybenzoxazine has good anti-corrosion properties and film-forming properties, and can effectively shield water and oxygen from contacting metal substrates, thereby achieving a good anti-corrosion effect. However, currently polybenzoxazine The research on oxazine as an anti-corrosion coating is relatively single, and it cannot exert its maximum effect. Moreover, after polybenzoxazine is used as a coating film, its strength is not good and its flame retardancy is not good, which cannot meet the needs of modern industries. Therefore, a new product was developed. A high-performance polybenzoxazine-based anti-corrosion coating has important scientific significance and commercial value

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a flame-retardant composite polybenzoxazine coating. Background technique [0002] The continuous development of industrial technology is accompanied by the wide use of metal materials, and the corrosion of metal and its components has attracted more and more attention due to the economic loss and lack of safety performance. At present, coatings are an important anti-corrosion method. , Its construction is simple, economical and applicable, and it is not restricted by the area and shape of the equipment, so it develops very rapidly, and various anti-corrosion coatings emerge in endlessly. As a new type of anti-corrosion coating material, polybenzoxazine has good anti-corrosion properties and film-forming properties, and can effectively shield water and oxygen from contacting metal substrates, thereby achieving a good anti-corrosion effect. However, currently polybenzoxazine The...
