Grâce à l'action de l'agent de protection infrarouge, les rayons infrarouge sont bloqués ou absorbés et de l'énergie lumineuse est convertie en énergie thermique, puis l'énergie thermique est isolée sur une surface grâce à l'action de l'agent de dissipation de chaleur et le blocage et la protection contre les rayons infrarouges sont améliorés ; l'ignifugation d'un produit est améliorée grâce à l'action de l'agent ignifuge inorganique ; grâce à l'action de l'agent de couplage au silane, l'agent de couplage au silane est intercalé entre la résine de corps principal EVA et l'agent de protection infrarouge, une couche liée de substrat inorganique-agent de couplage au silane-substrat organique est formée et la compatibilité de chaque matériau est améliorée.

Abstract: The present application provides a ceramic composite material and a preparation method therefor, a housing, and an electronic device. The ceramic composite material comprises ceramic particles and a metal oxide having a color. The ceramic particles and the metal oxide form a core-shell structure with the ceramic particles being a core and the metal oxide being a shell. The ceramic composite material of the present application has a colorful color effect, and the color distribution is relatively uniform. The housing composed of the ceramic composite material can have a plurality of colors, and the color distribution is relatively uniform.
