Description
Technical Field
The utility model relates to an synthetic leather technical field, concretely relates to compound TPU's PVC synthetic leather.
Background
Artificial leather is a kind of plastic product with appearance and hand feeling similar to leather and capable of replacing it, and is produced by coating fabric as base with synthetic resin and various plastic additives. The artificial leather mainly comprises PVC artificial leather and PU synthetic leather. However, the common PVC artificial leather has unsatisfactory cold resistance, low-temperature bending resistance, hydrolysis resistance, yellowing resistance, wear resistance, scratch resistance and other performances, and cannot meet special requirements of use. Therefore, there is a need for improvements in the prior art to avoid the disadvantages of the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the shortcoming and not enough among the prior art, provide a compound TPU's PVC synthetic leather that ageing resistance is strong, wear-resisting durable.
The utility model discloses a realize through following technical scheme:
the PVC artificial leather compounded with the TPU comprises a base cloth layer positioned at the bottom layer, a PVC film layer which is attached to the base cloth layer and positioned at the middle layer, and a TPU film layer which is compounded on the PVC film layer and positioned at the upper layer.
Further, the ratio of the thickness of the TPU film layer to the thickness of the PVC film layer is 1:2.
Further, the base cloth layer is a polyester cotton non-woven fabric base cloth layer.
Further, the surface of the TPU film layer is provided with anti-skid embossed patterns.
Further, the PVC film layer is fixedly attached to the base cloth layer through an adhesive, and the adhesive is evenly coated on the surface of the base cloth layer in a scraping mode.
Further, the blade coating quantity of the adhesive on the surface of the base cloth layer is 100-140 g per square meter.
Compared with the prior art, the utility model discloses a coating the synthetic leather surface with the wheel roller with TPU pulpiness material, make the synthetic leather surface form one deck TPU membrane, the TPU rete is compound in the upper surface on PVC rete, TPU is thermoplastic polyurethane elastomer, high tension has, high pulling force, obdurability, cold resistance, ageing-resistant characteristic, TPU and PVC are compound can combine both organically, improve PVC synthetic leather cold resistance, low temperature resistant zigzag, hydrolysis resistance, yellowing resistance, wear-resisting, performances such as resistant scratch, can satisfy the special needs that use.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Figure 1 is the utility model discloses compound TPU's PVC synthetic leather's structural schematic diagram.
In the figure: 1-a base cloth layer; 2-a PVC film layer; 3-TPU film layer.
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.
As shown in fig. 1 the utility model discloses a compound TPU's PVC synthetic leather, including the base cloth layer 1 that is in the bottom, laminate on base cloth layer 1 and be in medial PVC rete 2, compound on PVC rete 2 and be in the TPU rete 3 on upper strata. The TPU pulpiness material is coated on the surface of the artificial leather by a roller, so that a layer of TPU film is formed on the surface of the artificial leather, the TPU film layer 3 is compounded on the upper surface of the PVC film layer 2, the TPU is a thermoplastic polyurethane elastomer and has the characteristics of high tension, high toughness, cold resistance and aging resistance, the TPU and the PVC are compounded to organically combine the TPU and the PVC, the cold resistance, the low-temperature bending resistance, the hydrolysis resistance, the yellowing resistance, the wear resistance, the scratch resistance and other properties of the PVC artificial leather are improved, and the special requirements of use can be met.
As a specific implementation mode, the thickness ratio of the TPU film layer to the PVC film layer is 1:2, so that the cold resistance, low-temperature bending resistance, hydrolysis resistance, yellowing resistance, wear resistance, scratch resistance and other properties of the PVC artificial leather can be improved.
As a specific embodiment, the base fabric layer 1 is a polyester-cotton non-woven fabric base fabric layer, so that the PVC artificial leather has higher tensile strength and higher aging resistance.
The surface of TPU rete 3 is equipped with anti-skidding impressed watermark, improves the surface feel of PVC synthetic leather, makes PVC synthetic leather structure more firm.
The PVC film layer 2 is fixedly attached to the base cloth layer 1 through an adhesive, and the adhesive is uniformly coated on the surface of the base cloth layer 1 in a scraping mode.
The blade coating amount of the adhesive on the surface of the base cloth layer 1 is 100 g/square meter to 140 g/square meter, so that the PVC film layer 2 and the base cloth layer 1 are bonded more stably and firmly.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
