Abstract

The invention provides a water-based organically-modified inorganic zinc-rich primer which is prepared by mixing self-prepared water-based binder resin, over 500-mesh active zinc powder and a superfine mixed modified filler. The primer provided by the invention is environment-friendly, strong in adhesive force, chemical-mediator-corrosion-resistant, excellent in rust-proof and antiseptic property, high in hardness, wear-resistant, conductive and excellent in cathodic protection and is not affected by welding and cutting. The primer is widely applied to coating large steel structures, pipelines, oil tanks, ship locks, bridges, ships, coastal facilities, oil equipment and the like.

Description

Technical field: [0001] The invention relates to the field of paints, in particular to a water-based organically modified inorganic zinc-rich primer and a preparation method thereof. Background technique: [0002] With the promulgation of various harsh environmental protection laws and regulations at home and abroad, it is imperative to develop water-based heavy-duty anti-corrosion coatings. The annual loss caused by corrosion of steel structures in my country is as high as 500 billion yuan, accounting for 5.3% of the gross national product. Therefore, it is an important task of anticorrosion work to protect metals such as steel and make them perform their functions, prevent corrosion and prolong their service life. Water-based inorganic zinc-rich paint is based on inorganic silicate technology, mainly the reaction of inorganic silicate and zinc powder to form a network structure coating, which is a green and environmentally friendly coating. With a unique inorganic structu...
