FIG. 1 is a schematic view of the PVC-PP artificial leather of the present invention.
[ detailed description ] embodiments
The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, other embodiments obtained by the skilled in the art without creative work all belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a PVC-PP artificial leather 100, which can be applied to the fields of automobiles, home decoration, etc. From top to bottom, PVC-PP synthetic leather 100 is including surface treatment layer 1, PVC compact layer 2, tie coat 3, PP sponge layer 4 and back processing layer 5.
With continued reference to fig. 1, the surface treatment layer 1 and the back surface treatment layer 5 both use conventional treatment agents, which may be water-based paints or solvent-based paints. The surface treatment layer 1, also referred to as a functional layer, can be used to improve scratch resistance, abrasion resistance, smooth hand feeling, etc. of the surface of the PVC-PP artificial leather 100, and can be specifically selected according to actual needs. The back treatment layer 5 is disposed below the PP sponge layer 4, and when the PVC-PP artificial leather 100 is bonded to, for example, a door panel frame or an instrument panel frame using a vacuum adsorption process, the back treatment layer 5 may allow the PVC-PP artificial leather 100 to be better attached to the door panel frame or the instrument panel frame, and of course, in other embodiments, the back treatment layer 5 may not be disposed.
With continued reference to fig. 1, the PVC dense layer 2 serves as a skin layer structure, which is different from the PVC foamed layer in the prior art, and no foaming agent is added to the PVC dense layer 2. The PVC compact layer 2 comprises a first PVC compact layer 21 and a second PVC compact layer 22 which are arranged up and down, the formula of the first PVC compact layer 21 and the second PVC compact layer 22 can be selected from conventional formulas, for example, the formula of the first PVC compact layer 21 can be 60-65 parts by weight of PVC resin, 35-40 parts by weight of plasticizer, 1-2 parts by weight of stabilizer and 0-10 parts by weight of color paste, the formula of the second PVC compact layer 22 can be 60-65 parts by weight of PVC resin, 35-40 parts by weight of plasticizer, 1-2 parts by weight of stabilizer, 1-2 parts by weight of color paste and 3-5 parts by weight of flame retardant, and the PVC resin, the plasticizer, the stabilizer, the color paste and the flame retardant can be selected conventionally according to requirements and are not described in detail herein. Compare in only setting up one deck epidermis structure, the utility model discloses a will PVC compact layer 2 sets up to two-layer structure in order to realize can be through the fine setting first PVC compact layer 21 with the formulation of second PVC compact layer 22 reaches specific effect, as described in the formulation of preceding example, can add mill base in first PVC compact layer 21 in order to form the colour layer, not add the fire retardant in first PVC compact layer 22, but add the fire retardant in second PVC compact layer 22 in order to form fire-retardant layer, so both can realize fire-retardant effect, can guarantee again the homogeneity of mill base in first PVC compact layer 21, thereby guarantee the stability of PVC-PP synthetic leather 100's colour. Certainly, in other embodiments, the PVC dense layer 2 may also be provided as one or more layers, and certainly, the color paste and the flame retardant may also be added to the first PVC dense layer 21, because the flame retardant itself has a color and the dispersibility of the flame retardant is poor, the color paste may be unevenly distributed, and the color stability thereof is poor. In a preferred embodiment, the thickness of the PVC compact layer 2 is 0.45-0.6mm, the thickness of the first PVC compact layer 21 is 0.2-0.3mm, and the thickness of the second PVC compact layer 22 is 0.2-0.3mm, the present invention controls the total thickness of the PVC compact layer 2 and the thicknesses of the first PVC compact layer 21 and the second PVC compact layer 22, on one hand, the flexibility of the PVC-PP artificial leather 100 can be ensured, on the other hand, the processing feasibility of the PVC-PP artificial leather 100 can be ensured, if the total thickness of the PVC compact layer 2 is too thick, the hardness of the PVC-PP artificial leather 100 is too hard to be higher, and if the thicknesses of the first PVC compact layer 21 and the second PVC compact layer 22 are too thin, the artificial leather is easily damaged in the manufacturing process. The thickness of the first PVC dense layer 21 and the thickness of the second PVC dense layer 22 are preferably the same, so that the total thickness of the PVC dense layer 2 can be controlled to a minimum, contributing to the improvement of the flexibility of the PVC-PP artificial leather 100.
With continued reference to fig. 1, the adhesive layer 3 is used to adhere the PVC compact layer 2 and the PP sponge layer 4 together, and conventional glue may be used, which may be selected according to actual needs, and will not be described in detail here.
With continued reference to fig. 1, the shore hardness of the PP sponge layer 4 is 20-23HA, preferably 21-23HA, and more preferably 21 HA. The utility model discloses a select specific shore hardness PP sponge layer 4 makes PVC-PP synthetic leather 100 both has soft feel, has better outward appearance again. The thickness of the PP sponge layer 4 is preferably 1.5-2mm, and the present invention can ensure the whole flexibility of the parts combined with the PVC-PP artificial leather 100 and also the workability thereof by selecting the PP sponge layer 4 with a specific thickness, if the thickness of the PP sponge layer 4 is too thin, perhaps the flexibility of the PVC-PP artificial leather 100 itself can be, but the flexibility of the parts combined with the PVC-PP artificial leather 100 is not significantly improved, and if the thickness of the PP sponge layer 4 is too thick, the PVC-PP artificial leather 100 is difficult to process.
Some experimental data are provided below for further explanation:
example 1
The PVC-PP artificial leather comprises a surface treatment layer, a first PVC compact layer, a second PVC compact layer, a bonding layer, a PP sponge layer and a back treatment layer, wherein the surface treatment layer, the bonding layer and the back treatment layer are all selected conventionally, the first PVC compact layer is prepared from 60 parts by weight of PVC resin, 40 parts by weight of plasticizer, 2 parts by weight of stabilizer and 5 parts by weight of color paste, the second PVC compact layer is prepared from 60 parts by weight of PVC resin, 40 parts by weight of plasticizer, 2 parts by weight of stabilizer, 1 part by weight of color paste and 4 parts by weight of flame retardant, and the Shore hardness of the PP sponge is 20 HA.
Example 2 to example 4
Examples 2 to 4 respectively provide PVC-PP artificial leather, and the only difference between the PVC-PP artificial leather provided in examples 2 to 4 and the PVC-PP artificial leather provided in example 1 is the shore hardness of the PP sponge, and the specific values refer to table one.
Comparative examples 1 and 2
