Abstract

The utility model discloses foaming PU (Polyurethane) leather. The foaming PU leather comprises a base cloth layer, a dry bonding layer and a dry surface layer, wherein by regarding a use state as a standard, the dry bonding layer is fixedly bonded to the surface of the inner side of the base cloth layer; the dry surface layer is located at one side surface of the dry bonding layer back on to the base cloth layer; the foaming PU leather is also provided with a foaming PU layer with a foaming structure; the foaming PU layer is fixedly bonded between the dry surface layer and the dry bonding layer. The foaming PU layer with the foaming structure is arranged between the dry surface layer and the dry bonding layer, so that artificial leather which is better than genuine leather is rich in high resilience, well-rounded in hand feeling and strong in sensual appeal; the foaming layer is made of foaming PU resin, so that the foaming layer has high physical property and hydrolysis resistance; and the dry surface layer is provided with plump patterns which, so that strong stereoscopic sensation is obtained.

Description

Polyurethane foam PU leather

Technical field

The utility model relates to a kind of artificial leather, particularly a kind of polyurethane foam PU leather.

Background technology

Traditional artificial leather is that base cloth layer 1, dry method tack coat 2, dry method middle level 5 and dry method surface layer 3 form, and its each layer all is plain structure, so that artificial leather integral body is shrivelled, stiff, feeling does not have elasticity, and feel is poor, differs greatly with corium.

The utility model content

In order to overcome defects, the utility model provides a kind of polyurethane foam PU leather, simple, the high resilience of this polyurethane foam PU leather technique, and good hand feeling surmounts corium, and voluptuousness is strong, high physical property hydrolysis.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of polyurethane foam PU leather, comprise base cloth layer, dry method tack coat and dry method surface layer, to use state as benchmark, the dry method tack coat fixedly fits in the base cloth layer inner surface, the dry method surface layer is positioned at a dorsad side of base cloth layer of dry method tack coat, also be provided with the foaming PU layer with foaming structure, foaming PU layer fixedly is attached between dry method surface layer and the dry method tack coat.

As further improvement of the utility model, described dry method facing surface has decorative pattern.

As further improvement of the utility model, the decorative pattern concave-convex surface of described dry method facing surface.

As further improvement of the utility model, described foaming PU layer is polyurethane foam PU resin.

The beneficial effects of the utility model are: the utility model is by arranging the foaming PU layer with foaming structure between dry method surface layer and dry method tack coat, so that artificial leather high resilience, good hand feeling, surmount corium, voluptuousness is strong, and polyurethane foam PU resin is adopted in foaming layer, it has high physical property hydrolysis, at the dry method surface layer decorative pattern is set, the decorative pattern decorative pattern is full, and third dimension is strong.

The specific embodiment

Embodiment: a kind of polyurethane foam PU leather, comprise base cloth layer 1, dry method tack coat 2 and dry method surface layer 3, to use state as benchmark, dry method tack coat 2 fixedly fits in base cloth layer 1 inner surface, dry method surface layer 3 is positioned at a dorsad side of base cloth layer 1 of dry method tack coat 2, also be provided with the foaming PU layer 4 with foaming structure, foaming PU layer 4 fixedly is attached between dry method surface layer 3 and the dry method tack coat 2, this structure is so that synthetic leather high resilience and richness, feel surmounts corium, voluptuousness is strong, high physical property hydrolysis.

Described dry method surface layer 3 surfaces have decorative pattern, and full decorative pattern makes the synthetic leather surface more attractive in appearance.

The decorative pattern concave-convex surface on described dry method surface layer 3 surfaces has third dimension, and the flower type is full.

Described foaming PU layer is polyurethane foam PU resin.
