Embodiment 1

[0067] The invention discloses a non-porous self-breathing PVC artificial leather, which has the characteristics of low price and long service life of ordinary artificial leather, and has the waterproof and breathable function. The waterproof and breathable function comes from the structure and material of the self-breathing PVC artificial leather, wherein the non-porous self-breathing PVC artificial leather includes a non-porous self-breathing surface layer and a breathable bottom layer with a microporous structure.

[0068] The self-breathing surface layer contains hydrophilic polymer functional materials, such as water-soluble polyols and carboxylates; the breathable bottom layer is a breathable PVC foam layer, and the self-breathing surface layer and the breathable bottom layer adopt the transfer method and (or) surface treatment method Combining together, the way of combining generally adopts the way of bonding (fitting).

Abstract

The invention provides non-porous self-breathing PVC artificial leather which comprises a non-porous self-breathing surface layer and a breathable bottom layer with a microporous structure, the self-breathing surface layer and the breathable bottom layer are attached together by adopting a transfer method and (or) a direct coating method, the self-breathing surface layer contains water-soluble polyhydric alcohol and carboxylate, and the breathable bottom layer is a breathable PVC foaming layer. According to the non-porous self-breathing PVC artificial leather, water vapor is discharged out ofthe leather through the temperature difference and the humidity difference, self-breathing is achieved, the moisture and air discharging effect is achieved, the outer layer is of a non-porous structure, the waterproof effect is achieved, and the problem that PVC leather is poor in breathability is effectively solved.

Description

technical field [0001] The invention relates to the technical field of artificial leather production, in particular to a non-porous self-breathing PVC artificial leather and a preparation method thereof. Background technique [0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of it. It mainly includes PVC artificial leather, PU artificial leather and PU synthetic leather. Due to its high strength, easy processing and low cost, artificial leather has been widely used as a substitute for genuine leather. [0003] However, the use of artificial leather is still very different from genuine leather, such as hygiene. Because artificial leather is not breathable or has poor ventilation function, the interior of artificial leather is in a high temperature and high humidity environment for a long time, and bacteria and fungi multiply and cause odor problems. [0004] In some PU artificial leathers, since the substrate (wet proce...
