Abstract

A silicate-reinforced polyurethane coating is characterized in that the polyurethane coating is prepared from the following ingredients in parts by weight: acetone, sodium hydroxide solution, anhydrous zinc chloride, n-butylaldehyde, cyclohexane, anhydrous magnesium sulfate, benzenetetracarboxylic anhydride, 1,2-propylene glycol, terephthalic acid, montmorillonite, talcum powder, sodium tripolyphosphate, silane coupler KH-560, absolute ethyl alcohol, butanediamine, acrylonitrile, ferric chloride, 1-butyl-3-methylimidazolium hexafluorophosphate, N-phenyl-N'-isopropyl-p-phenylenediamine, propylene glycol butyl ether, N,N'-lutidine, triethylamine, methylene diphenyl diisocyanate, appropriate amount of hydrochloric acid solution and appropriate amount of deionized water. The polyurethane coating hereof has the advantages of firm coating bonding, uniform thickness, strong salt water resistance, good wear resistance, good anti-corrosion performance, non-toxicity and environmental protectionand the like.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to a silicate reinforced polyurethane coating 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 ha...
