Abstract
The invention discloses a graphene high-performance anticorrosive paint with long-acting anticorrosive performance and a preparation method and a product thereof. The graphene high-performance anticorrosive paint is prepared from the following raw materials (by weight): 250-300 parts of a resin matrix, 2-10 parts of a wetting dispersant, 1-5 parts of an antifoaming agent, 25-40 parts of an anti-settling agent, 40-70 parts of a paint solvent, 550-700 parts of rust-proof pigments and fillers, 5-20 parts of a viscosity regulator, 4-10 parts of a coupling agent, and 90-110 parts of a curing agent,wherein the resin matrix comprises a block copolymer of modified small-molecular epoxy resin and modified macromolecular epoxy resin. The graphene high-performance anticorrosive paint provided by theinvention has good permeability and adhesion and excellent anticorrosive performance; shelf life of the anticorrosive coating is greatly prolonged; and good economic benefits and ecological benefitscan be formed.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to a graphene high-efficiency anti-corrosion coating and a preparation method and product thereof. Background technique [0002] Seawater, which is rich in electrolytes and charges, will have a stronger rusting and corrosive effect on metals than freshwater due to electrochemical action. Therefore, in the harsh marine environment, marine hulls, bridges, and platforms are prone to corrosion and rust, seriously affecting the overall performance, resulting in reduced strength of hulls, bridges, and platforms, local corrosion damage, and reduced navigation speed. One of the most effective and commonly used methods for metal equipment anti-corrosion is to coat the metal surface with an anti-corrosion coating to isolate the corrosive medium and the metal substrate. Then, in view of the above situation, some anti-corrosion coatings with outstanding performance are needed. However, tradi...
