Silicone resin modified magnesium hydroxide: improving performance and application potential
Magnesium hydroxide (Mg(OH)₂) is a halogen-free flame retardant with important applications in multiple industries. However, its dispersibility and compatibility issues in polymer matrices limit its wider application. The study of silicone resin modified magnesium hydroxide aims to solve these problems and improve its performance in flame retardancy and reinforcement materials.
Principle of silicone resin modification
Surface modification: The silicone resin is fixed on the surface of magnesium hydroxide by chemical bonding or physical adsorption to enhance its compatibility with the polymer.
Improve compatibility: The organic part of the silicone resin improves the compatibility of magnesium hydroxide with the polymer matrix and improves the overall performance of the composite material.
Enhanced flame retardant performance: The siloxane network formed by the silicone resin at high temperature helps to form a stable protective layer and improve the flame retardant effect.
Application field
Flame retardant: Modified magnesium hydroxide is a high-efficiency flame retardant that reduces the generation of smoke and harmful gases during combustion.
Composite materials: As a reinforcing agent, it improves the mechanical properties, thermal stability and weather resistance of composite materials.
Coating materials: Improve the durability, corrosion resistance and fire resistance of coatings.
Environmental protection: As an adsorbent, remove heavy metal ions or organic pollutants in flue gas desulfurization and wastewater treatment.
Specific examples
Silicone-modified acrylic resin: Use specific silicone modifiers to modify the surface of magnesium hydroxide to improve compatibility with polymer matrix and flame retardancy.
