In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. It should be noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

The embodiment of the utility model provides degradable biological leather, which comprises a base cloth layer 1, an adhesive layer 2 made of first biological base resin and a surface layer 3 made of second biological base resin, wherein the base cloth layer 1, the adhesive layer 2 and the surface layer 3 are sequentially stacked; the adhesive layer 2 is adhered to the upper surface of the base fabric layer 1, and the surface layer 3 is adhered to the upper surface of the adhesive layer 2. The first bio-based resin and the second bio-based resin are bio-based resin materials with different proportions, and have different physical properties such as hardness and toughness;

the utility model is described as follows: the biological leather comprises a base cloth layer 1, a bonding layer 2 and a surface layer 3 which are sequentially stacked, wherein the bonding layer 2 and the surface layer 3 are both made of a biological base resin material, the biological base resin material is common in that the bonding layer is made of natural raw materials and is easy to decompose, when waste products are treated, the natural degradation rate can be achieved through composting, the natural degradation rate is 86% -92%, compared with chemical leather in the prior art, the chemical leather does not need to be burnt and decomposed, the natural degradation is achieved through composting, the bonding layer 2 and the surface layer 3 are naturally decomposed, the base cloth layer 1 is left, and the base cloth layer 1 can be recycled, so that the raw material cost is reduced, the emission of carbon and harmful gases is reduced, and the decomposition treatment cost is reduced.
