Description

Novel composite leather structure

Technical Field

The utility model relates to a leather technical field specifically is a novel composite leather structure.

Background

The existing leather fabric is applied to a plurality of fields, and leather can be used in automobile seats, clothes or industries and the like. For example, when leather is applied to a sightseeing bus, in order to improve the flexibility of the leather, foamed cotton is usually added on the cloth surface of the leather, and the cloth and the foamed cotton are not firmly connected due to more gaps of the cloth, so that the foamed cotton and the leather are separated after the leather is used for a period of time, and the leather is also bubbled and delaminated after being used for a long time, so that the defective rate of products related to the leather is higher, and the durability is poorer.

Therefore, in view of the above, research and improvement are made on the existing structure and defects, and a novel composite leather structure is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

An object of the utility model is to provide a novel composite leather structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel composite leather structure, includes the leather layer, the leather layer includes cortex and bed of cloth, be equipped with the cloth adhesive layer between cortex and the bed of cloth, the non-leather side on leather layer is equipped with TPR glue layer, and TPR glue layer paints on the cloth surface, TPR glue layer surface is equipped with the TPU water proof membrane, the TPU water proof membrane bonds through TPR glue layer and leather layer, TPU water proof membrane lower surface is equipped with the liquid glue film, liquid glue film surface bonds and has the foaming cotton.

Furthermore, a plastic frame is arranged on the lower surface of the foaming cotton, reinforcing holes are formed in the surface of the plastic frame, adhesive layers are arranged on the edges of the plastic frame and the reinforcing holes, and the adhesive layers are adhered to the foaming cotton.

Further, the TPU waterproof membrane is a white transparent membrane, is made by adopting a nanotechnology, and is larger than the area of the leather layer, so that the TPU waterproof membrane is stably connected with the leather layer.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a TPU water proof membrane improves the fastness of foaming cotton and leather layer adhesion, and the adhesion more even, at the in-process that uses the leather, ensures that delaminating, the tympanic bulla's condition can not appear in the leather, improves the quality of leather, and the TPU water proof membrane still prevents that the water logging foaming is cotton, uses at outdoor seat, for example cable car seat, sightseeing vehicle seat etc. effectively prolongs the life of seat.

In the figure: 1. a leather layer; 2. TPR glue layer; 3. a TPU waterproof film; 4. foaming cotton; 5. a plastic frame; 6. and (7) reinforcing the holes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a novel composite leather structure, includes leather layer 1, leather layer 1 feels good, and wear resistance is strong, is applied to the seat and can keeps the life of seat, leather layer 1's non-leather face is equipped with TPR glue layer 2, leather layer 1 includes cortex and bed of cloth, be equipped with the cloth glue film between cortex and the bed of cloth, TPR glue layer 2 is paintd on the cloth surface, TPR glue layer 2 surface is equipped with TPU waterproof membrane 3, TPU waterproof membrane 3 bonds with leather layer 1 through TPR glue layer 2, TPU waterproof membrane 3 is white transparent film, TPR glue layer 2 makes TPU waterproof membrane 3 firm be connected with leather layer 1, TPU waterproof membrane 3 lower surface is equipped with the liquid glue film, liquid glue layer surface bonds and has foaming cotton 4, foaming cotton 4 lower surface is equipped with plastic frame 5; plastic frame 5 protection foaming cotton 4 avoids the wearing and tearing of foaming cotton 4, 5 surfaces of plastic frame are equipped with

reinforcement hole

6, and 6 increases of reinforcement hole and the area of contact of foaming cotton 4, improve the fastness that both are connected, plastic frame 5 and 6 edges in reinforcement hole are equipped with the adhesive layer, and the adhesive layer and the cotton 4 bonding of foaming, and foaming cotton 4 improves the thickness and the compliance of leather layer 1.

Specifically, during preparation, the leather layer 1 is a finished product, the TPR glue layer 2 is uniformly coated on the cloth layer at the back of the leather layer 1, the TPR glue layer 2 is in a semi-solidified state, then the TPU waterproof film 3 with the length and width larger than that of the leather layer 1 is paved on the TPR glue layer 2, the TPR waterproof film is connected more firmly through extrusion, the foaming cotton 4 is injected into the surface of the TPU waterproof film 3, and finally, the plastic frame 5 is connected with the foaming cotton 4 through the adhesive, so that the novel composite leather is obtained.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
