Problems solved by technology

[0008] In the prior art of the aforementioned Patent Document 1, in addition to flexibility such as bendability and softness, functions in terms of strength such as surface scratch resistance and tear strength are also improved, but there is a problem with the user's skin or clothing. The phenomenon that other parts come into contact with the surface of the skin layer and rub repeatedly, and the problem that sufficient abrasion resistance or chemical resistance cannot be obtained

Embodiment 1～12 and comparative example 1～8

[0111] The components described in Examples 1 to 12 shown in Table 1 and Comparative Examples 1 to 8 shown in Table 2 were blended in their respective ratios, and molded into a non-foamed layer with a thickness of 0.3 mm by calender molding 11 and a foam layer 12 with a thickness of 0.6mm. The non-foamed layer 11 and the foamed layer 12 are overlapped with the base material 2 (a two-component polyurethane adhesive is applied to a plush knitted fabric woven with 100% polyester 83T crimped silk), heated and heated. After making it foam, it is pressed with a squeeze roll and a rubber roll, so that the foam layer 12 is bonded to the base material 2 while being squeezed to obtain a image 3 Synthetic resin leather A (A3) with a concave-convex pattern 4 is shown.

[0112] Specifically, the non-foaming layer 11 of the film 1 is a plasticizer (diisophthalic acid diiso Decyl ester: DIDP), plasticizer (epoxidized soybean oil), heat stabilizer (barium-zinc mixed stabilizer), filler (ca...

Abstract

Provided is a synthetic resin leather having high flexibility and good strength, and abrasion resistance with respect to being repeatedly subjected to rubbing and chemical resistance with respect to human contact. A surface treatment agent obtained by carbodiimide crosslinking of a mixture of polycarbonate urethane and ester urethane is applied to a surface side of film (1), the main component ofwhich is a vinyl chloride resin, and as a result thereof, a surface treatment layer (1a) having excellent flexibility, abrasion resistance, and oleic acid resistance is formed.

Description

technical field [0001] The present invention relates to a synthetic resin leather having a film mainly composed of vinyl chloride resin such as PVC and a manufacturing method thereof. Background technique [0002] Conventionally, as such synthetic resin leather, there is a synthetic resin leather used for cushion materials and the like, in which a synthetic resin layer composed of vinyl chloride resin and the like is bonded to a base fabric via bonding. Agent bonding, on the surface of the synthetic resin layer, in order to protect the surface of the synthetic resin layer and maintain the strength of the synthetic resin layer, and to provide the touch of the synthetic resin layer, a skin layer is formed, and an embossing pattern is appropriately implemented on the surface of the skin layer Or printed patterns are laminated with the synthetic resin layer, or embossed patterns or printed patterns are applied after lamination (for example, refer to Patent Document 1). [0003]...
