Abstract

The invention discloses a novel environment-friendly coating with superhigh marine environment corrosion resistance and a preparation method and application thereof. The environment-friendly coating with superhigh marine corrosion resistance consists of the following components in part by weight: a main agent comprising 22 to 35 parts of low-viscosity solvent-free epoxy resin, 9 to 15 parts of activated thinner, 0.2 to 5 parts of aid, 5 to 8 parts of organic solvent, 0.5 to 15 parts of toner, 10 to 25 parts of first filler, 20 to 45 parts of second filler and 0.5 to 5 parts of thixotropic agent, and a curing agent comprising 60 to 90 parts of amine resin, 10 to 30 parts of activated thinner, 2 to 8 parts of aid and 2 to 10 parts of organic solvent. During use, the main agent and the curing agent are uniformly mixed, and the mixture is applied to the surface of a substrate. A film formed by the coating is high in corrosion resistance and low in content of volatile organic compounds (VOC), does not contain any toxic or harmful substance, can be universally used in a drinking water tank, and also can be used for a ship ballast tank, a ship bottom, a deck and each position of a marine platform.

Description

technical field [0001] The invention relates to the field of environment-friendly coatings, in particular to a novel environment-friendly coating with super corrosion resistance to marine environment, its preparation method and application. Background technique [0002] Heavy-duty anti-corrosion coatings are playing an increasingly important role in national economic construction and national defense construction. For example, shipbuilding, machinery and equipment manufacturing, national defense industry and other fields are inseparable from heavy-duty anti-corrosion coatings. Since the reform and opening up, my country's heavy-duty anti-corrosion coatings have developed rapidly and have made great progress. However, most of the anti-corrosion coatings are still based on solvent-based coatings. The comprehensive performance of the entire heavy-duty anti-corrosion industry is not high, and there is still a significant gap compared with developed countries. Most of the occas...
