More Information
Summary:The present invention refers to a method to prepare nanometric magnesium hydroxide particles. These particles have an average diameter that ranges from 90 to 110nm, and that could range from 20 to 160nm, with monodisperse and stable characteristics for greater than 12 month in a wide range of concentrations. This process includes 3 stages: one reaction stage performed in two steps, one of maturation and one of purification. The first step of the reaction is developed in micro blending zone, and the second one is the stabilization of suspension. During the second stage, the particles maturation is developed through a chemical-mechanic treatment. The last stage is designed to purify and concentrate the material, as well as its preparation to integrate it to the desired form. The obtained particles are re-dispersable in different means, such as water, aldehyde resins, phenolic resins, nitrocellulose, polyurethane, vinylic, acrylic, alcohol, and wide variety of organic materials and polymers such as high and low density polypropylene, Nylon, ABS and/or any combination of the same
