279 results about "Zinc phosphate" patented technology

Zinc phosphate is an Inorganic compound with the formula Zn₃(PO₄)₂)(H₂O)₄. This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment. One common agent is sodium pyrophosphate.

Water-based corrosion and rust prevention coating and preparation method thereof

This invention relates to the field of anti-corrosion coating technology, specifically to a water-based corrosion-inhibiting anti-corrosion coating and its preparation method. When zinc phosphate is used alone as a corrosion inhibitor in water-based anti-corrosion coatings, it tends to agglomerate and has poor compatibility with resins. The protective coating formed on the metal surface by these water-based anti-corrosion coatings exhibits poor and unstable corrosion resistance. To address these problems, this invention provides a water-based corrosion-inhibiting anti-corrosion coating composed of two components, A and B. Component A contains a self-made composite corrosion inhibitor, ZnP-PEG-IPTS-GO. This composite corrosion inhibitor, through the bridging of IPTS, chemically bonds GO, PEG, and zinc phosphate, achieving an organic combination of "physical shielding" and "active passivation," significantly improving the overall anti-corrosion performance of the coating.
