Embodiment Construction

[0018] The preparation method of multi-functional environment-friendly leather fabric, the first step is to coat the PU fabric layer on the release paper. When coating the PU fabric layer, the coloring material, aromatic agent and negative ion are firstly mixed according to the weight percentage, wherein the negative ion accounts for 15%, and the aromatic The additive accounts for 0.05%, and the rest is coloring material. Mix these three with PU material evenly, filter, and go to the production line to coat the PU fabric layer with the required thickness on the release paper, and dry it at QDRGD135 degrees; the second step is to coat PVC. Foaming material layer, when coating the PVC foaming material layer, the coloring material, aromatic agent, and negative ions of the PVC foaming material layer are first calculated by weight percentage, wherein negative ions account for 15%, aromatic agents account for 0.05%, and the rest are coloring materials. Mix these three with the foamin...

Abstract

The invention relates to leather, particularly to PU (polyurethane) leather with a function of continuously releasing negative ions and fragrance and aims to provide a preparation method of multifunctional environment-friendly leather fabric capable of continuously releasing the negative ions and the fragrance. The multifunctional environment-friendly leather fabric is prepared through steps as follows: step one, coating release paper with a PU fabric layer; step two, applying a PVC (polyvinyl chloride) foamed material layer, and performing plasticizing; step three, coating a plasticized layer with a PVC foaming layer, and enabling PVC to foam at the temperature of 180 DEG C; step four, performing gluing attachment; step five, separating from the release paper. The multifunctional environment-friendly leather fabric has the characteristics that peculiar smell in a room or an automobile is adjusted and eliminated and the like.

Description

technical field [0001] The invention relates to a kind of leather, especially PU leather with the functions of continuously releasing negative ions and fragrance. Background technique [0002] my country is the world's largest producer and consumer of artificial leather and synthetic leather. Its production capacity and output are 73% and 69% of the world's respectively. In China, people are used to calling the artificial leather produced with PU resin as PU artificial leather (referred to as PU leather). The artificial leather produced with PU resin and non-woven fabric as raw material is called PU synthetic leather (synthetic leather for short). It is customary to collectively refer to the above three types of leather as synthetic leather. [0003] Artificial leather and synthetic leather are an important part of the plastic industry and are widely used in various industries of the national economy. The production of artificial leather and synthetic leather has a history ...
