Brucite-based magnesium hydroxide flame retardant: a new flame retardant option for EVA materials

In the field of materials science, EVA (ethylene-vinyl acetate copolymer) is widely used in various industrial fields due to its excellent physical properties and chemical stability. However, the flammability of EVA has also caused concerns about its safety. In order to improve the flame retardant properties of EVA, researchers began to explore the use of brucite-based magnesium hydroxide as a flame retardant. Preparation method of brucite-based magnesium hydroxide flame retardant and its application effect in EVA.

Preparation of brucite-based magnesium hydroxide flame retardant

The preparation of brucite-based magnesium hydroxide flame retardant usually adopts the assembly method, which involves compounding brucite with other flame retardant components to improve its application performance in polymers such as EVA. Through surface coating technology, the preparation of nitrogen-magnesium-phosphorus composite high-efficiency and high-performance composite flame retardant can be achieved. This modification method can not only improve the flame retardant efficiency, but also improve the processing performance and mechanical properties of the material.

Application of surface modification technology

In order to improve the compatibility of brucite-based magnesium hydroxide flame retardant with EVA, surface modification technology is widely used. By physically coating or chemically reacting a layer of organic flame retardant on the surface of brucite, its compatibility with polymers can be significantly improved. For example, the preparation of melamine resin microencapsulated composite flame retardant not only improves the flame retardant properties of EVA, but also improves the mechanical properties of the material.

Application of brucite-based magnesium hydroxide in EVA

EVA materials have a low oxygen index and are extremely flammable. By adding brucite-based magnesium hydroxide flame retardant, the flame retardant properties of EVA can be effectively improved. Studies have shown that when modified brucite-based magnesium hydroxide is applied to EVA, its oxygen index and limiting oxygen index can be significantly improved, while the mechanical properties of the material are improved.

The preparation and application of brucite-based magnesium hydroxide flame retardant provides an effective solution for the flame retardant modification of EVA materials. This flame retardant not only improves the flame retardant properties of the material, but also improves the mechanical properties and processing properties of the material, providing a new direction for the development of halogen-free flame retardants. With the continuous deepening of research, the application prospects of brucite-based magnesium hydroxide flame retardant in EVA materials will be broader, providing new possibilities for achieving safer and more environmentally friendly material applications.
