Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a high-strength and high-adhesion anti-corrosion coating. Background technique [0002] When metal is corroded, it turns into an oxidized state, and its strength, plasticity, toughness and other mechanical properties are greatly reduced, the geometric shape of the construction machinery products composed of it is destroyed, the wear between construction machinery products increases, the service life is shortened, and even fires are caused. , explosion and other catastrophic accidents. Anti-corrosion coating is an important material to prevent metal corrosion. It forms a coating film that can prevent water and oxygen from penetrating, thereby preventing its metal material from being corroded. As a new type of anti-corrosion coating material, polybenzoxazine has good Anti-corrosion performance and film-forming performance can effectively shield water, oxygen from c...

[0002] When metal is corroded, it turns into an oxidized state, and its strength, plasticity, toughness and other mechanical properties are greatly reduced, the geometric shape of the construction machinery products composed of it is destroyed, the wear between construction machinery products increases, the service life is shortened, and even fires are caused. , explosion and other catastrophic accidents

Anti-corrosion coating is an important material to prevent metal corrosion. It forms a coating film that can prevent water and oxygen from penetrating, thereby preventing its metal material from being corroded. As a new type of anti-corrosion coating material, polybenzoxazine has good Anti-corrosion performance and film-forming performance can effectively shield water, oxygen from contact with metal substrates, so as to achieve good anti-corrosion effect. However, the strength of this waterproof coating for engineering machinery is not high, and some coating products are added with enhanced materials. Significantly reduces adhesion again, causes product performance not good enough, can not be popularized and used widely, therefore, it is very necessary to develop a kind of anticorrosion coating with strong adhesion and high strength
