Description
Technical Field
The utility model relates to the technical field of automobile seats, in particular to a soft touch seat back plate.
Background
Currently, the back boards of automobile chairs on the market mainly have the following forms: the surface cover sewing type backboard, the injection molding type backboard and the injection molding + cladding backboard. Complex modeling of the surface cover sewing type backboard is difficult to realize, sewing time is overlong, labor cost is high, and wrinkles are easy to appear on the surface. The injection molding type backboard is made of PP, ABS and other materials, so that the overall cost is high, the die cost is high, the texture is hard, and the passengers cannot be protected more. The overall cost of the injection molding and coating backboard is higher, the die cost is higher, the surface is coated with a layer of soft fabric to achieve the purpose of soft touch, the smell and VOC (volatile organic compounds) can be greatly influenced by the glue used during coating, and in addition, the labor cost and the material cost can be greatly increased.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model aims to provide the integrally formed soft touch chair back plate which is low in cost and simple in manufacturing process.
In order to achieve the above purpose, the utility model provides a soft touch chair back plate, which comprises a fabric layer, a composite cotton layer, a plastic film layer and a polyurethane foaming layer, wherein the composite cotton layer is compounded on the front surface of the fabric layer, the plastic film layer is compounded on the front surface of the composite cotton layer, and the polyurethane foaming layer is integrally cast and molded on the front surface of the plastic film layer; the Shore A hardness of the fabric layer side of the soft touch chair back plate is 5-50HA, the Shore A hardness of the polyurethane foaming layer side of the soft touch chair back plate is 30-95HA, and the Shore A hardness of the fabric layer side is always smaller than the Shore A hardness of the polyurethane foaming layer side.
In the scheme, the method comprises the following steps: the composite cotton layer is a polyurethane soft foam composite cotton layer with the thickness of 1-5 mm.
In the scheme, the method comprises the following steps: the fabric layer, the composite cotton layer and the plastic film layer are compounded into a whole by adopting flame compounding, glue spraying or glue film pasting technology.
In the scheme, the method comprises the following steps: the fabric layer adopts fabric, artificial leather or dermis.
In the scheme, the method comprises the following steps: the back of the fabric layer is provided with a storage bag.
The beneficial effects of the utility model are as follows: firstly, compounding a fabric layer, a compound cotton layer and a plastic film layer together, then laying the fabric layer, the compound cotton layer and the plastic film layer on the bottom surface of a lower model cavity, and then closing and casting the mould to integrally form a chair back plate with soft touch; the plastic film layer can prevent polyurethane foaming materials from penetrating into the composite cotton layer and the fabric layer during casting, so that the hardness of the composite cotton layer and the fabric layer is prevented from being influenced by the polyurethane foaming materials; the double-layer arrangement of the composite cotton layer and the fabric layer can further ensure the soft touch of the chair back plate.

Detailed Description
As shown in figures 1-2, the soft touch chair back plate mainly comprises a surface material layer 1, a composite cotton layer 2, a plastic film layer 3 and a polyurethane foaming layer 4.
The composite cotton layer 2 is compounded on the front surface of the fabric layer 1, the plastic film layer 3 is compounded on the front surface of the composite cotton layer 2, and the polyurethane foaming layer 4 is integrally cast and formed on the front surface of the plastic film layer 3.
The Shore A hardness of the fabric layer 1 side of the soft touch chair back plate A is 5-50HA, the Shore A hardness of the polyurethane foaming layer 4 side of the soft touch chair back plate A is 30-95HA, and the Shore A hardness of the fabric layer 1 side is always smaller than the Shore A hardness of the polyurethane foaming layer 4 side.
Preferably, the composite cotton layer 2 is a polyurethane soft foam composite cotton layer with the thickness of 1-5 mm.
Preferably, the fabric layer 1, the composite cotton layer 2 and the plastic film layer 3 are combined into a whole by flame compounding, glue spraying or glue film pasting technology.
Preferably, the fabric layer 1 is made of fabric, artificial leather or dermis.
Preferably, the back of the fabric layer 1 is provided with a storage bag.
According to the utility model, the fabric layer 1, the composite cotton layer 2 and the plastic film layer 3 are compounded together by adopting a flame compounding process, then are laid on the bottom surface of the lower model cavity, and then are subjected to closed-die casting, so that the chair back plate with soft touch feeling is integrally formed. The plastic film layer 3 can prevent polyurethane foaming materials from penetrating into the composite cotton layer 2 and the fabric layer 1 during casting, so that the hardness of the composite cotton layer 2 and the fabric layer 1 is prevented from being influenced by the polyurethane foaming materials; the double-layer arrangement of the composite cotton layer 2 and the fabric layer 1 can further ensure the soft touch of the chair back plate.
