The invention provides a self-cleaning heat-insulation reflecting material which comprises an aerogel layer, a first aluminum foil layer, a first flame-retardant adhesive layer, a flame-retardant bubble layer, a second flame-retardant adhesive layer, a second aluminum foil layer and a self-cleaning layer which are sequentially arranged; the self-cleaning layer is a modified polytetrafluoroethylene layer; the second flame-retardant adhesive layer is prepared from the following components in parts by weight: 20-25 parts of polyurethane adhesive, 5-10 parts of curing agent, 40-50 parts of ethyl acetate, 20-30 parts of methanol, 5-10 parts of aminated graphene, 5-10 parts of nano silicon nitride and 10-15 parts of dopamine. The invention also provides a preparation method of the self-cleaning heat-insulation reflecting material. The self-cleaning layer with the modified polytetrafluoroethylene as the main component is combined with the flame-retardant adhesive layer and the aerogel layer, has low heat conduction, high flame retardance and self-cleaning function, is suitable for breeding shed buildings, and reduces energy consumption and cleaning strength. |
