In order to realize the technical purpose, the utility model discloses a technical scheme as follows:

an antibacterial waterproof synthetic leather comprises a waterproof layer, an antibacterial layer, a base cloth layer and a polyurethane layer; the outer layer of the base cloth layer is bonded with the antibacterial layer, and the outer layer of the antibacterial layer is bonded with the waterproof layer; the inner layer of the base cloth layer and the outer layer of the waterproof layer are both provided with a polyurethane layer;

a waterproof breathable patch is arranged on the polyurethane layer on the outer layer of the waterproof layer; the outer layer of the waterproof breathable patch is a PTFE (polytetrafluoroethylene) film, and the cloth of the inner layer is bonded or sewn with the polyurethane layer.

Furthermore, the waterproof breathable patch is in a water drop shape, the whole antibacterial waterproof synthetic leather is divided into an upper end and a lower end, the upper end of the waterproof breathable patch faces the upper end of the antibacterial waterproof synthetic leather, and the lower end of the waterproof breathable patch faces the lower end of the antibacterial waterproof synthetic leather; the waterproof breathable patches are transversely stacked one on another in a row.

Furthermore, the surface of the polyurethane layer is provided with air holes, and the air holes are rhombus-shaped.

Furthermore, the inner polyurethane layer and the outer polyurethane layer are spliced or sewed on two sides of the whole antibacterial waterproof synthetic leather.

Furthermore, the waterproof layer is formed by coating a layer of silver colloid on cotton cloth fibers.

Further, the antibacterial layer is an antibacterial fabric.

Compared with the prior art, the utility model, following beneficial effect has:

waterproof and antibacterial properties in the synthetic leather are improved by additionally arranging a waterproof layer and an antibacterial layer on the basis of the existing synthetic leather; meanwhile, waterproof breathable patches which are transversely stacked are arranged on the outermost polyurethane layer, so that the waterproof and breathable performance of the whole antibacterial waterproof synthetic leather outer layer is improved.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

As shown in fig. 1 and 2, an antibacterial waterproof synthetic leather includes a waterproof layer 1, an antibacterial layer 2, a base fabric layer 3, and a polyurethane layer 4; the outer layer of the base cloth layer 3 is bonded with the antibacterial layer 2, and the outer layer of the antibacterial layer 2 is bonded with the waterproof layer 1; the inner layer of the base cloth layer 3 and the outer layer of the waterproof layer 1 are both provided with a polyurethane layer 4; a waterproof breathable patch 5 is also arranged on the polyurethane layer 4 on the outer layer of the waterproof layer 1; the outer layer of the waterproof and breathable patch 5 is a PTFE film, and the cloth of the inner layer is bonded or sewn with the polyurethane layer 4. The PTFE film has the waterproof and breathable effects, and the cloth has the effect of being conveniently adhered or sewn with the polyurethane layer 4.

As shown in fig. 3, the waterproof breathable patch 5 is in a water drop shape, the whole antibacterial waterproof synthetic leather is divided into an upper end and a lower end, the upper end of the waterproof breathable patch 5 faces the upper end of the antibacterial waterproof synthetic leather, and the lower end of the waterproof breathable patch 5 faces the lower end of the antibacterial waterproof synthetic leather; the waterproof breathable patches 5 are stacked one on top of the other in a row transversely. The waterproof and breathable patches 5 stacked from top to bottom ensure that when the whole antibacterial and waterproof synthetic leather is invaded by water or other liquid substances, the water or the liquid can drip on the outer layer surface of the antibacterial and waterproof synthetic leather from top to bottom along the water-drop-shaped surface layer. The water-drop-shaped waterproof breathable patch 5 also plays a role in beautifying the appearance of the whole antibacterial waterproof synthetic leather.

As shown in fig. 4, the surface of the polyurethane layer 4 is provided with air holes 6, and the air holes 6 are rhombus-shaped. The ventilation performance of the surface of the polyurethane layer 4 is ensured through the flat ventilation holes 6 with the rhombic structures, and meanwhile, when the surface of the polyurethane layer 4 is stretched or expanded, the tension degree of the ventilation holes 6 on the surface of the polyurethane layer 4 can be improved to the maximum extent, so that the ventilation of the outer polyurethane layer 4 or the sweat discharging effect of the inner polyurethane layer 4 is improved.

The polyurethane layer 4 is spliced or sewed on the two sides of the whole antibacterial waterproof synthetic leather. The whole polyurethane layer 4 can be coated with the waterproof layer 1, the antibacterial layer 2 and the base cloth layer 3, and the stretchable elastic limit of the whole antibacterial waterproof synthetic leather is improved.

The waterproof layer 1 is formed by coating a layer of silver colloid on cotton cloth fiber. The water leakage property of the cotton cloth fiber material is blocked by coating a layer of hard silver colloid on the cotton cloth fiber, so that the external water is directly isolated on the surface of the waterproof layer 1.

The antibacterial layer 2 is made of antibacterial fabric. The antibacterial effect inside the whole antibacterial waterproof synthetic leather is improved through the antibacterial fabric, and external bacteria are prevented from entering the base cloth layer 3.

waterproof and antibacterial performances in the synthetic leather are improved by additionally arranging a waterproof layer 1 and an antibacterial layer 2 on the basis of the existing synthetic leather; meanwhile, the waterproof and breathable patches 5 which are transversely stacked mutually are arranged on the outermost polyurethane layer 4, so that the waterproof and breathable performance of the whole antibacterial waterproof synthetic leather outer layer is improved.

The above has been introduced in detail an antibiotic waterproof synthetic leather that this application provided. The description of the specific embodiments is provided to facilitate an understanding of the structure and design of the present application.
