Ultrasonic oscillation technology: an innovative method to improve the surface dispersibility and flame retardant performance of magnesium hydroxide

In the field of materials science, magnesium hydroxide has attracted much attention due to its excellent flame retardant properties. However, its poor dispersion in the polymer matrix limits its application effectiveness. So how can ultrasonic oscillation composite modification technology significantly improve the surface dispersion of magnesium hydroxide and enhance its flame retardant effect, providing new ideas for the development of green flame retardant materials.

The principle of ultrasonic oscillation composite modification

Ultrasonic oscillation technology uses the mechanical effect and cavitation effect generated by high-frequency sound waves to physically and chemically modify the surface of magnesium hydroxide. This technology enables the modifier to be more evenly distributed on the surface of magnesium hydroxide, forming a uniform coating, thereby improving its dispersion in organic media.

Improves surface dispersion effect

Through ultrasonic oscillation treatment, the surface of magnesium hydroxide is effectively modified, and its dispersibility in organic solvents such as xylene is significantly improved. The sedimentation speed of modified magnesium hydroxide in the organic phase decreases, and the viscosity of the suspension decreases, indicating that its dispersion has been significantly improved.

Enhance flame retardant effect

As an environmentally friendly flame retardant, the flame retardant effect of magnesium hydroxide has been significantly improved after composite modification by ultrasonic oscillation. Modified magnesium hydroxide can more effectively form a carbonized layer during the combustion process, reducing combustion smoke. At the same time, its decomposition product magnesium oxide can form a protective layer on the surface of the polymer, improving the efficiency of isolating air and further preventing combustion.

Advantages of ultrasonic oscillation composite modification

Magnesium hydroxide prepared by ultrasonic oscillation technology has better dispersion and spherical surface morphology. These characteristics significantly improve its dispersion and compatibility in the polymer matrix. This modification method not only improves the flame retardant properties of magnesium hydroxide, but also enhances its application potential in composite materials.

Ultrasonic oscillation composite modification technology provides an effective surface modification method for the application of magnesium hydroxide, which significantly improves its surface dispersion and flame retardant effect. The application of this technology can not only improve the flame retardant properties of materials, but also promote the development of environmentally friendly flame retardant materials and bring new research directions to the field of materials science.
