Abstract

The invention relates to a vinyl anticorrosion coating material and a manufacturing method thereof. The method includes: adding bisphenol A type epoxy vinyl ester resin into styrene, a co-polymerization solution containing an acid group, silicone oil, a polyacrylate solution and aminopropyltriethoxysilane, dispersing, dissolving, stirring at a high speed, adding fumed silica, titanium dioxide, barite, silica powder and carbon black under stirring, grinding by a sand mill to prepare a liquid mixture, adding glass flakes into the liquid mixture, dispersing at a high speed, and adding a modified urea solution during the dispersion step. A B solution comprises cobalt naphthenate and a styrene mixed solution. A C solution comprises methyl ethyl ketone peroxide, methyl ethyl ketone and a phthalate mixed solution. When the coating material is to be used, an A solution, the B solution and the C solution are mixed. A coating of the coating material has excellent adhesive force, impact resistance, wear resistance, resistance to heat and humidity, resistance to sea water and salt fog resistance and long working lifetime, and is suitable for splashing-zone and underwater corrosion resistance of ocean platforms, marine work steel structures, and the like.

Description

technical field [0001] The invention relates to a vinyl anticorrosion coating and a manufacturing method, which can be used for anticorrosion in the splash zone and underwater of offshore platforms and marine steel structures. Background technique [0002] Vinyl ester resin has good chemical corrosion resistance and seawater resistance. Now it is mostly used to make glass fiber reinforced plastic to protect steel structures. The cost of glass fiber reinforced plastic is high, and the construction is complicated, so the application range is limited. When vinyl ester resin is used as a coating, the pot life is short, it is easy to polymerize, the coating is hard and brittle, and the impact resistance is poor. Contents of the invention [0003] The purpose of the present invention is to provide a vinyl anticorrosion coating and its manufacturing method, to solve the problems of short pot life and easy polymerization when vinyl ester resin is used as coating, and solve the pro...
