Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] like Figure 1 - Figure 3As shown, the utility model provides a technical solution: a crack-resistant flexural artificial leather, comprising a protective layer 1, an intermediate base fabric layer 2, a filling layer 3 and a bottom base fabric layer 4, a functional layer 5 is provided on the surface of the protective layer 1, a rubber sleeve 51 is filled in the functional layer 5, a rubber column 52 is provided inside the rubber sleeve 51, an elastic rope 53 is provided between the rubber column 52 and the inner wall of the rubber sleeve 51, two ends of the elastic rope 53 are respectively fixedly connected to the rubber column 52 and the rubber sleeve 51, and the outer wall of the rubber sleeve 51 is fixedly connected with the same elastic rope 53;

[0021] The diameter of the elastic rope 53 connected to the outside of the rubber sleeve 51 is twice the diameter of the elastic rope 53 connected to the inside of the rubber sleeve 51. The rubber sleeves 51 are opened at equal intervals on the surface of the protective layer 1. The rubber columns 52 are fixedly connected by the elastic rope 53. The elastic rope 53 is made of elastic rubber bands woven in an interlaced manner. In actual use, when the leather body is pulled and twisted, the rubber sleeve 51, the rubber column 52 in the functional layer 5 and the elastic rope 53 connected thereto will be stressed at the same time. During the stress process, the elastic force of the elastic rope 53 itself will generate an elastic force in the opposite direction along the direction of the force, thereby buffering the pulling force, thereby preventing the leather body from automatically returning to its original position after being twisted, and at the same time reducing the stress on the leather body, thereby increasing its service life;

[0022] The protective layer 1 includes a cracked layer 11, a waterproof layer 12 and a fiber braided layer 13. The surface of the cracked layer 11 is provided with cracked grooves. The cracked layer 11, the waterproof layer 12 and the fiber braided layer 13 are sutured and fixed. The waterproof layer 12 is supported by polyester fibers. The waterproof layer 12 is filled with polyethylene particles. The cracked grooves can increase the anti-slip performance of the surface of the leather body and improve the wear resistance. The waterproof layer 12 can increase the waterproofness of the leather body.

[0023] The protective layer 1 and the intermediate base fabric layer 2 are fixedly bonded by a polyolefin composite adhesive, and an epoxy resin adhesive layer 6 is provided between the intermediate base fabric layer 2 and the filling layer 3. The epoxy resin adhesive layer 6 is made of epoxy resin adhesive, and the intermediate base fabric layer 2 and the filling layer 3 are fixedly connected by the epoxy resin adhesive layer 6;

[0024] A wear-resistant layer 41 is provided at the bottom of the bottom base fabric layer 4, and rubber particles are provided on the surface of the wear-resistant layer 41. The rubber particles on the surface of the wear-resistant layer 41 are embedded in the side of the wear-resistant layer 41 away from the bottom base fabric layer 4. The bottom base fabric layer 4 and the filling layer 3 are sewn and fixed. The wear-resistant layer 41 is provided on the bottom base fabric layer 4, which can increase the wear resistance of the bottom surface of the leather, so that the leather as a whole has better wear resistance.

[0025] Working principle:

[0026] like Figure 1 - Figure 3As shown, when the leather is actually used, when the leather body is pulled and bent, the rubber sleeve 51, the rubber column 52 and the elastic rope 53 connected thereto in the functional layer 5 will be stressed at the same time. During the stress process, the elastic force of the elastic rope 53 itself will generate an elastic force in the opposite direction along the stress direction, thereby buffering the pulling force, thereby preventing the leather body from automatically returning to its original position after being bent, and at the same time reducing the stress on the leather body, thereby increasing its service life;

[0027] A wear-resistant layer 41 is provided on the bottom base fabric layer, which can increase the wear resistance of the bottom surface of the leather, so that the leather as a whole has better wear resistance.
