Abstract

The invention relates to superfine fiber synthetic leather and a preparation method thereof, and belongs to the technical field of synthetic leather. The superfine fiber synthetic leather consists of a superfine fiber synthetic leather base fabric, a foamed bottom sealing filling layer, a coating top layer, a coating bonding layer and a surface treatment layer, wherein the foamed bottom sealing filling layer comprises the following components in part by weight: 10 to 30 parts of water-borne comprehensive resin, 30 to 40 parts of water-borne foamed resin and 1 to 5 parts of waterproof agent; the coating top layer comprises the following components in part by weight: 70 to 90 parts of water-borne polyurethane, 3 to 10 parts of water-borne color paste, 1 to 5 parts of flatting agent and 1 to5 parts of handfeel agent; the coating bonding layer comprises the following components in part by weight: 70 to 90 parts of water-borne polyurethane bonding agent, 3 to 10 parts of water-borne colorpaste and 1 to 5 parts of flatting agent; and the surface treatment layer comprises the following components in part by weight: 1 to 5 parts of waterproof agent and 1 to 5 parts of handfeel agent. The superfine fiber synthetic leather has good properties of scratch resistance, pollution resistance and water resistance, and has wide application prospect; and by adoption of the superfine fiber synthetic leather, clean production can be realized.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a superfine fiber synthetic leather and a preparation method thereof. Background technique [0002] Microfiber is the fiber that is currently being researched and developed in the fiber field, and it is also an important development direction for future fibers. The superfine fiber synthetic leather obtained by impregnating polyurethane with superfine fiber non-woven fabric is close to natural leather in terms of appearance, texture and comfort, but its hygienic performance is poor and its scratch resistance is insufficient, which is difficult to meet requirements for outdoor use. In terms of production, the current superfine fiber synthetic leather is basically produced by solvent-based resin, which causes great environmental pollution. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a superfine fiber synthe...
