Abstract

The invention relates to the technical field of coatings, and in particular relates to a solvent-free epoxy coating for a ballast tank and a preparation method of the solvent-free epoxy coating. The solvent-free epoxy coating comprises a component A and a component B, wherein the component A comprises the following components in parts by mass: 25-30 parts of bisphenol F epoxy resin, 3-5 parts of liquid petroleum hydrocarbon resin, 5-10 parts of an active diluent, 0.5-1.0 part of a thixotropic agent, 5-10 parts of titanium dioxide, 40-50 parts of barium sulfate, 0.5-1.0 part of a dispersing agent, 0.5-0.8 part of a defoaming agent and 3-5 parts of a silane coupling agent; the component B is prepared from the following components in parts by mass: 13.2 to 15.36 parts of fatty amine adduct, 2.8 to 3.9 parts of cashew phenolic aldehyde amine and 0.1 to 0.5 part of an accelerant; the bisphenol F epoxy resin is matched with the special reactive diluent, so that the viscosity of the system isreduced, the flexibility is improved, and the crosslinking density is improved; the fatty amine adduct is low in viscosity and matched with the cashew phenolic aldehyde amine, low-temperature curingcan be achieved, the drying speed is increased, meanwhile, the chemical resistance of the cashew phenolic aldehyde amine is excellent, and high corrosion resistance is achieved while the chemical resistance of the solvent-free epoxy coating is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a solvent-free epoxy coating for ballast tanks and a preparation method thereof. Background technique [0002] At present, most of the products that are used in the ballast tanks of ships in the market are still solvent-based epoxy coatings. If the construction is carried out in such a closed space as the ballast tanks, the solvent-based coatings will cause fire hazards due to poor ventilation and difficult volatilization of organic solvents. It will cause harm to the construction personnel, and the use of solvent-free epoxy coatings avoids the use of a large amount of organic solvents. Due to their high mixing viscosity, most solvent-free epoxy products often need to be heated at low temperature or use two-component spraying equipment. The construction is difficult, and the high investment in equipment limits their use and promotion. At the same time, in terms of salt spray co...
