Abstract

The invention provides a polyurethane paint with strong adhesive which is characterized by being prepared from the raw materials in parts by weight; acetone, sodium hydroxide solution, anhydrous zincchloride, n-butanal, cyclohexane, anhydrous magnesium sulfate, succinic anhydride, diethylene glycol, terephthalic acid, dipropylene glycol, palm oil, p-phenylenediamine, methylene silicone oil, phthalic anhydride, 2,2'-azobisisovaleronitrile, hydroxyethyl acrylate, methacrylic acid, nano calcium carbonate, hydroxyapatite, 4-methyl-6-tert-butylphenol, propylene glycol monomethyl ether, benzyltriethylammonium chloride, dimethylethanolamine, methylene diphenyl diisocyanate, a defined amount of hydrochloric acid solution and a defined amount of deionized water. The polyurethane paint is firm in binding, uniform in thickness, strong in salt-water resistance, good in wear resistance and anti-corrosion performance, is non-toxic and environment-friendly and the like.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to a polyurethane coating with strong adhesion and a preparation method thereof. Background technique [0002] Ductile iron pipes are mainly called centrifugal ductile iron pipes, which have the characteristics of iron essence, steel performance, good ductility, good sealing effect, and easy installation. In recent years, with the continuous expansion of urbanization, the demand for pipes, especially large-diameter pipes, has been increasing, and it has played an increasingly important role in the transformation of water supply pipelines and pipe networks in major cities at home and abroad. As these projects The preferred material for engineering is widely used in urban construction projects such as water transmission and gas transmission, providing a huge market for the ductile iron pipe industry. However, the transportation of urban sewage, natural gas and other substances h...
