Abstract
Basic zinc cyanurate fine particles are produced by subjecting a mixed slurry to wet dispersion using a dispersion medium at a temperature in the range of 5 to 55° C., the mixed slurry being formed by blending water, cyanuric acid, and at least one component selected from zinc oxide and basic zinc carbonate such that the cyanuric acid concentration is 0.1 to 10.0 mass % with respect to water.
Claims18
Basic zinc cyanurate fine particles, having an average particle diameter D50, as measured by a laser diffraction method, of from 80 to 900 nm and a specific surface area of from 20 to 100 m2/g,
- wherein the particles have a primary particle diameter, as observed under a transmission electron microscope, of from 100 to 800 nm on a major axis and a diameter of from 10 to 60 nm on a minor axis, wherein a ratio between the maior axis and the minor axis is 5 to 25.
