Abstract

The invention discloses a water-soluble inorganic zinc-rich primer. The water-soluble inorganic zinc-rich primer is characterized by being prepared from, by mass, 15-25% of inorganic modified resin and 75-85% of inorganic modified zinc powder. The inorganic modified resin is prepared from, by weight, 12-14 parts of potassium silicate, 2-4 parts of sodium silicate, 7-9 parts of aqueous colloidal silica, 6-10 parts of deionized water, 4-5 parts of silane coupling agent and 5-7 parts of flexible emulsion. The inorganic modified zinc powder is prepared from, by weight, 60-70 parts of zinc powder, 1-3 parts of anti-settling agent, 2-3 parts of talcum powder and 1-3 parts of thickening agent. The water-soluble inorganic zinc-rich primer is large in adhesive force and high in drying speed, materials are adopted comprehensively and matched reasonably, no organic solvent is discharged, harm to the environment is avoided, and environment friendliness is realized.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based inorganic zinc-rich primer. Background technique [0002] Inorganic zinc-rich primer has excellent weather resistance, chemical corrosion resistance, and temperature resistance. It is an anti-corrosion primer for steel surfaces with excellent performance. Water-based inorganic zinc-rich primer is suitable for coating on steel structure substrates primer. The existing water-based zinc-rich primer has low viscosity, poor adhesion to paint, easy to fall off from the surface of the steel structure, short anti-rust period, slow drying speed, and environmental protection performance is not up to standard. In order to meet the market demand, it is urgent to develop a product with strong adhesion, fast drying speed and low VOC content. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a water-based inorgan...
