The invention provides an insulating and antibacterial automobile ceiling fabric. Silicon dioxide aerogel is used as a functional packing layer, the very poor water absorption property of the silicon dioxide aerogel is beneficial to keeping the overall dryness of the automobile ceiling fabric, due to addition of hyperbranched polymer bactericide, not only is the formation of the aerogel felt accelerated, but also the mechanical strength of the aerogel felt is improved, the bacteria can be effectively killed and inhibited, the automobile ceiling fabric is prevented from mold or bacteria, and the body health of passengers is ensured. The automobile ceiling fabric provided by the invention integrates an insulating material aerogel felt layer and a stainless steel vacuum insulating layer, and a good insulating effect is achieved as the aerogel felt is of a porous structure of nano grade aperture and a heat conduction path is blocked by the vacuum insulating layer. The invention further provides a preparation method of the aerogel felt. Due to addition of the hyperbranched polymer bactericide as a functional auxiliary agent, the aerogel felt has properties of sterilization and bacteriostasis, is very poor in water absorption property and is beneficial to keeping the overall dryness of the automobile ceiling fabric.

The invention provides a nano-silver water-based polyurethane for self-sterilizing thin-walled materials and a preparation method thereof.
