Waterproof synthetic leather easy to ventilate

The synthetic leather comprises an inner foaming layer, an outer base layer, an inner base layer and a resin coating, the edges of the outer base layer and the inner base layer are mutually bonded to form an interlayer structure, the inner foaming layer is filled between the interlayer of the outer base layer and the interlayer of the inner base layer, the resin coating is bonded on the surface of the outer base layer, and the resin coating is filled between the interlayer of the outer base layer and the interlayer of the inner base layer. A breathable layer is connected to the outer wall of the inner base layer in a sewing mode, and the surface of the resin coating is sequentially coated with a protective layer and an outer waterproof layer. The protective layer is added on the surface of the conventional resin coating, so that the wear resistance of the resin coating can be effectively improved, the waterproof performance of the resin coating is prevented from being reduced due to collision, extrusion and s
