Abstract

The invention discloses a water-resistant anticorrosive coating which is characterized by being prepared from the following components in parts by weight: 10-20 parts of amino modified hyperbranched SBS, 40-50 parts of glycidyl methacrylate / allyl pentafluorobenzene / 3- (4-fluorophenyl) -2-acrylonitrile / allyl phenyl sulfone / vinyl triethoxysilane copolymer, 15-25 parts of an inorganic filler, 0.5-1.5parts of an initiator, 1-3 parts of a dispersant and 1-3 parts of a film-forming assistant. The invention also discloses a preparation method of the water-resistant anticorrosive coating. The waterproof anticorrosive coating disclosed by the invention has the advantages of excellent comprehensive performance, obvious waterproof anticorrosive effect, good performance stability, weather resistance,workability, adaptability and durability, and strong adhesion with a base material.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant and anti-corrosion coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of world science and technology and social production, the use of metal materials has increased significantly, and they are known as the "skeleton of industry". Metal materials are widely used in large-scale steel equipment, components, pipelines and other steel structure facilities due to their excellent mechanical properties. They are the guarantee of the safety and quality of national key projects and large-scale projects. However, metal materials are easy to corrode, especially in coastal and inland hot and humid environments, because the environment contains harmful corrosive media such as chlorides and sulfides, the problem of metal material corrosion is particularly prominent, which in turn affects its service life, and t...
