▎ 摘　　要

NOVELTY - Photocatalytic dry hot-pressing composite core material comprises 84.5-95 wt.% ultrafine glass fiber cotton , 5-15 wt.% photocatalytic nanoparticles and 0.5-2.5 wt.% coupling agent. The photocatalytic nanoparticles includes photocatalytic nanoparticle A comprises photocatalytic nanoparticle B. USE - Used as the photocatalytic dry hot-pressing composite core material. ADVANTAGE - The method improves the porosity of the glass fiber cotton and the load of the photocatalytic nano particles. The material has photocatalytic sterilization effect and reduces its low thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the photocatalytic dry hot-pressing composite core material.
