Composite heat preservation and insulation structure

The utility model relates to a combined type heat preservation and insulation structure which is composed of an inner heat insulation material layer, a heat insulation material layer with a heat insulation coating, an outer heat insulation material layer and an outer protection layer. An inner heat insulation material layer, a heat insulation material layer with a heat insulation coating, an outer heat insulation material layer and an outer protection layer are sequentially and fixedly arranged outside an object to be subjected to heat preservation and are fixed. The composite thermal insulation structure adopts the thermal insulation material layer with the thermal insulation coating, so that the thermal insulation effect of the thermal insulation structure is ensured, the overall thickness is reduced, the use amount of the conventional thermal insulation material layer is reduced, and the cost is reduced. After installation, the thickness of the outer layer of a heat-insulated object is reduced, the install
