Abstract

Disclosed are melamine and its preparing method and application, with the characteristics that add 10-300 portions of inorganic flaming retardant, 100-1000portions of water into reactor with agitator and thermometer, make them to be dispersion in 50-130deg.C, the add into 0-300portions of antiflaming synergistic agent, 50-100 portions of melamine and 50-200 portions of cyanuric acid (emulsion or cream of ), which are stirred for 5 minutes to 2 hours in 50-150deg.C, in the course, can add into 100-1000 portions of water, generate the emulsion or cream of cyanuric acid covering inorganic flaming retardant which are filtered, are centrifugal separated, dried and scattered to be 0.01-500um cyanuric acid covering inorganic flaming retardant.

Description

1. Technical field [0001] The invention relates to a melamine cyanuric acid microcapsule inorganic flame retardant and a preparation method thereof, belonging to the field of flame retardant preparation. 2. Background technology [0002] Inorganic flame retardants such as magnesium hydroxide, aluminum hydroxide, phosphate, borate, and molybdate are currently rapidly developing environmentally friendly flame retardants, and their consumption accounts for 80% of the total consumption of flame retardants. Inorganic flame retardants have the advantages of being halogen-free, non-toxic, low-smoke, and cheap, and are widely used in the field of polymer material preparation. The flame retardant mechanism of different inorganic flame retardants is different. Metal hydroxide inorganic flame retardants (magnesium hydroxide, aluminum hydroxide) mainly release bound water through pyrolysis, which plays a cooling and flame retardant role; while phosphate And borates (such as ammonium po...
