Preparation of waterborne inorganic zinc-rich coatings
Abstract：waterborne inorganic zinc-rich coating is heavy-duty antirust coatings，which is
synthesize with alkali metal silicate solution as the base, the metal zinc powder as antirust
pigment and some other additives. Because of its good adhesion, weather resistance, abrasion
resistance, heat resistance, radiation resistance, solvent resistance, environmental safety,
antistatic characteristics, it was widely used in ships, containers, and other heavy-duty antirust
facilities. Firstly, high modulus potassium silicate aqueous solution preparation is researched,
investigating the reaction temperature, the modulus of the solution of potassium silicate.The
results showed that 60℃ prepare the optimum reaction temperature to potassium silicate
solution,and adding a certain amount of KOH with high modulus to improve the stability of the
potassium silicate solution to prevent the gel. High modulus potassium silicate solution as the
base material to study potassium silicate modulus and dosage of zinc impact to corrosion
resistance of the coating, hardness, drying time, drying time, heat resistance. .The research
results show that potassium silicate solution increase of molar ratio d and the increase of zincpowder can improve performance of waterborne inorganic zinc-rich coatings, when the molar
ratio of the potassium silicate solution n≥4.9, basic material: zinc powder = 1:3, waterborne
inorganic zinc rich coating of the hardness, heat resistance, corrosion resistance, etc. With good
performance..
