In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention are described below with reference to the accompanying drawings.

The first embodiment:

as shown in figure 1, soft shrink type polyurethane synthetic leather comprises a base layer 1, a PU resin layer 2 is arranged on the base layer 1, a TPU rubber layer 3 is arranged on the PU resin layer 2, and a matte oil wax layer 4 is coated on the TPU rubber layer 3.

The PU resin layer 2 adopts soft polyurethane PU which mainly has a thermoplastic linear structure, has better stability, chemical resistance, rebound resilience and mechanical property than PVC foaming materials, has smaller compression deformability and good heat insulation and anti-seismic properties.

The Tpu rubber layer 3 has excellent wear resistance, very good touch, difficult deformation, weather resistance durability and easy cleaning.

The matte oil wax layer 4 can make the synthetic leather have natural effect and luster.

The working principle is as follows:

the synthetic leather has good anti-seismic and heat insulation effects through the PU resin layer 2, the wear resistance of the synthetic leather is increased through the TPU rubber layer 3, the surface of the synthetic leather is easy to clean through the TPU rubber layer, and the gloss of the synthetic leather is increased through the matte oil wax layer 4, so that the gloss of the synthetic leather is more natural.

Second embodiment:

referring to fig. 2, based on a soft and shrinkable polyurethane synthetic leather provided in the first embodiment of the present application, a second embodiment of the present application provides another soft and shrinkable polyurethane synthetic leather. The second embodiment is only the preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the difference of the soft shrinkage polyurethane synthetic leather provided by the second embodiment of the present application lies in that the soft shrinkage polyurethane synthetic leather further includes: a plurality of hollow rubber blocks 5 are fixedly connected to the matte oil wax layer 4, and the hollow rubber blocks 5 are uniformly distributed on the surface of the matte oil wax layer 4.

The rubber block 5 is semicircular, so that damage to the synthetic leather can be reduced when an external obstacle collides with the rubber block 5.

The working principle is as follows:

the rubber block 5 reduces the collision force when the obstacle collides with the synthetic leather, thereby reducing the damage of the obstacle to the synthetic leather and prolonging the service time of the synthetic leather.

Third embodiment

Referring to fig. 3, a third embodiment of the present application provides another soft and shrinkable polyurethane synthetic leather based on the soft and shrinkable polyurethane synthetic leather provided in the second embodiment of the present application.
