Air heat insulation mattress with thermal resistance adjustable function and preparation method thereof

The invention provides an air heat insulation mattress with a thermal resistance adjustable function and a preparation method thereof. The mattress is composed of a shell, tie bars and an air bag. The mattress shell is composed of chemical fiber fabric and hot melt adhesive. The tie bars are composed of chemical fiber nets; the air bag is composed of a rubber material capable of being folded for multiple times, a chemical fiber fabric, a hot melt adhesive and an aluminized reflecting film. The air heat insulation mattress has the characteristic of adjustable heat resistance, the inflation volume in the air bag can be adjusted, the shape of the air bag also changes, so that the position of the aluminum-plated reflecting film in the air bag can change among the bottom layer, the middle layer and the top layer of the mattress, and the change of the internal structure also influences the size distribution of the air chamber in the mattress; therefore, the heat conductivity coefficient of the mattress is changed,
