Windproof heat preservation cloth

The invention discloses a windproof heat preservation cloth, which comprises a surface layer, a middle layer and an inner layer, the middle layer is formed by pressing cotton between the surface layer and the inner layer through an ultrasonic cotton pressing process to form a cotton sandwiched layer, the upper side and the lower side of the cotton sandwiched layer are respectively provided with a base cloth layer, the surface layer is an aluminum film layer and/or a printing layer, and the inner layer is a silver-coated layer. A PU coating is sprayed on the inner side of the surface layer, the waterproof grade is PU2000, and a hydrophobic coating is arranged on the outer side of the surface layer. After ultrasonic cotton pressing, pressing seams are formed in the middle layer, a plurality of rhombic blocks are formed through the pressing seams, and heat preservation cotton is limited in the rhombic blocks. The middle cotton layer is adopted, the supporting performance is good, and the heat preservation perfor
