According to the utility model, the anti-breaking layer and the mildew-proof sterilization layer are added, so that the toughness of the leather is increased, the sterilization and mildew prevention are facilitated, the leather is more durable, and the perforation arranged on the anti-breaking layer facilitates the connection between the three adjacent layers to be tighter.
Description
Technical Field
The utility model relates to the field of leather, in particular to durable pu leather.
Background
Common leathers include natural leathers and synthetic leathers, the synthetic PU leather being the skin of the polyurethane component. The PU leather is widely applied to decoration of bags, clothes, shoes, vehicles and furniture, and is increasingly determined by the market, but the synthetic leather can be used for a long time or placed for a long time, mould can be bred on the leather to cause damage or color change, and meanwhile, some leathers are easy to damage due to the action of external force in the transportation process, so that the PU leather with strong durability and difficult damage is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide durable pu leather.
In order to achieve the purpose, the utility model provides the following technical scheme:
the durable pu leather comprises a base cloth layer, wherein a breakage-proof layer, a mildew-proof sterilization layer and a pu surface layer are sequentially arranged on the top surface of the base cloth layer from bottom to top; the anti-breaking layer is fixedly connected with the anti-mildew and sterilization layer at the top and the base cloth layer at the bottom through hot melt adhesive; a plurality of through holes are uniformly distributed on the anti-breaking layer, and the hot melt adhesive is filled in the through holes.
The base cloth layer, the breakage-proof layer and the mildew-proof sterilization layer are connected together through hot melt adhesive, a plurality of through holes are formed in the breakage-proof layer, hot melt adhesive is filled in the through holes, the through holes can enable the base cloth layer, the breakage-proof layer and the mildew-proof sterilization layer to be connected more tightly, meanwhile, the softness of the breakage-proof layer is increased, and on the basis that the breakage-proof layer plays a breakage-proof role, the phenomenon that the PU leather is hard due to the increase of the breakage-proof layer is avoided; the mildew-proof sterilization layer effectively sterilizes, prevents leather from mildewing, and effectively protects leather.
Further, the perforation shape includes a honeycomb shape, a circular shape, a triangular shape, or a square shape.
Further, the base cloth layer is made of non-woven fabric materials.
Further, the base cloth layer is formed by blending bamboo charcoal fibers and polyurethane fibers.
Further, the anti-breaking layer is formed by curing polyurethane resin.
Further, the mildew-proof sterilization layer is made of nano silver materials.
Furthermore, the thickness of the mildew-proof sterilizing layer is 0.11-0.21 mm.
Furthermore, the PU surface layer is high-wear-resistance PU leather.
Further, the total thickness of the hot melt adhesive and the anti-breaking layer is 0.15-0.25 mm.
Compared with the prior art, the leather has the advantages that the anti-breaking layer and the mildew-proof sterilization layer are added, the toughness of the leather is improved, the sterilization and mildew prevention are facilitated, the leather is durable, and the perforation arranged on the anti-breaking layer facilitates the connection between the three adjacent layers to be tighter.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1: a durable PU leather, refer to fig. 1-2, comprises a base cloth layer 1, wherein the base cloth layer 1 is made of non-woven fabric materials, a breakage-proof layer 2, a mildew-proof sterilization layer 3 and a PU surface layer 4 are sequentially arranged on the top surface of the base cloth layer 1 from bottom to top, the breakage-proof layer 2 is formed by curing polyurethane resin, the mildew-proof sterilization layer 3 is made of nano silver materials, the thickness of the mildew-proof sterilization layer 3 is 0.11-0.21mm, and the PU surface layer 4 is high-wear-resistant PU leather; the anti-breaking layer 2 is fixedly connected with the top mildew-proof sterilization layer 3 and the bottom base cloth layer 1 through hot melt adhesives 5; a plurality of through holes 6 are uniformly distributed on the anti-breaking layer 2, the shapes of the through holes 6 comprise honeycomb shapes, round shapes, triangular shapes or square shapes, the hot melt adhesive 5 is filled in the through holes 6, and the total thickness of the hot melt adhesive 5 and the anti-breaking layer 2 is 0.15-0.25 mm.
The base cloth layer 1, the breakage-proof layer 2 and the mildew-proof sterilization layer 3 are connected together through hot melt adhesives 5, a plurality of through holes 6 are formed in the breakage-proof layer 2, the through holes 5 are filled in the through holes 6, the base cloth layer 1, the breakage-proof layer 2 and the mildew-proof sterilization layer 3 can be connected more tightly through the through holes 6, meanwhile, the softness of the breakage-proof layer 2 is increased, and on the basis that the breakage-proof layer 2 plays a breakage-proof role, the phenomenon that the PU leather is provided with hardness due to the increase of the breakage-proof layer 2 is avoided; the mildew-proof sterilization layer 3 effectively sterilizes, prevents leather from mildewing and effectively protects leather.
Example 2: the present embodiment is different from embodiment 1 in that the base fabric layer 1 is formed by blending bamboo charcoal fiber and polyurethane fiber. The advantages of comparative example 1 are: the base cloth layer 1 has a certain sterilization and antibacterial effect, and the auxiliary mildew-proof sterilization layer 3 enhances the sterilization effect.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
