AI Technical Summary

Technical Problem

In the existing technology, the poor interfacial compatibility between ordinary aluminum hydroxide and polypropylene resin matrix leads to uneven dispersion of the filler system, numerous interfacial defects, and difficulty in achieving synergistic improvement of flame retardancy and mechanical properties.

Method used

Modified aluminum hydroxide was used and treated with KH570 coupling agent before being radically polymerized with acrylate and trimethylolpropane triacrylate to form a cross-linked polymer coating layer, constructing a three-dimensional network structure, which improved the dispersibility of the filler and enhanced the interfacial bonding.

Benefits of technology

It significantly improves the mechanical and flame-retardant properties of composite materials, achieving synergistic enhancement of flame retardancy and mechanical properties, and forming a tightly integrated composite system.

Abstract

This invention provides a flame-retardant composite material synergistically reinforced with aluminum hydroxide functional filler and its preparation method. Modified aluminum hydroxide is added, which is an intermediate product of freshly prepared aluminum hydroxide coupled with KH570, and a composite formed by free radical polymerization of acrylate and trimethylolpropane triacrylate. By adding modified aluminum hydroxide to the composite material, on the one hand, the modified aluminum hydroxide exhibits good compatibility with the resin matrix, effectively improving the filler dispersion and reducing interfacial defects. Combined with glass fiber and inorganic fillers, it achieves synergistic reinforcement, significantly improving the material's mechanical properties. On the other hand, the modified aluminum hydroxide also possesses a three-dimensional network structure, enabling it to fully impregnate, coat, and interpenetrate with the resin matrix and other components, forming a tightly bonded, uniformly integrated composite system. This strengthens the bonding strength between phases, further enhancing the material's flame-retardant and mechanical properties.
