| titleOfInvention | Organic silicon modified PAE polyurea coating |
| abstract | The invention discloses an organic silicon modified PAE polyurea coating, which comprises a component A and a component B, wherein the preparation method of organic silicon modified polyaspartic acid ester in the component A comprises the following steps: reacting vinyl alcohol or vinyl epoxy compound with hydrogen-terminated silicone oil to obtain functionalized silicone oil; reacting the functionalized silicone oil with dialkyl maleate or maleic anhydride to obtain dimeric siloxane maleate; reacting polysiloxane maleate with aliphatic dibasic primary amine to obtain the product; the preparation method of the isocyanate silicone oil curing agent in the component B comprises the following steps: reacting vinyl dihalogen or polyhalogen compound with hydrogen-containing silicone oil to obtain polyhalogenated silicone oil; reacting polyhalogenated silicone oil with phthalimide salt, and then heating hydrazine to obtain polyamino silicone oil; dripping trichloromethyl chloroformate into polyamino silicone oil, and irradiating with incandescent lamp for reaction. According to the invention, polysiloxane is respectively introduced to the side chains of the component A and the component B, so that the PAE polyurea coating with good leveling property, high corrosion resistance, high temperature resistance and high coating strength can be obtained. |
