Artificial leather and preparation method thereof

Abstract

The invention discloses artificial leather and a preparation method thereof. The artificial leather comprises the following components in parts by weight: a base material, a shell fabric, 100 parts of a bonder and a piece of base cloth, wherein the shell fabric comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin and 50-60 parts of a plasticizer; the base material comprises the following components in parts by weight: 100 parts of the polyvinyl chloride resin, 70-80 parts of the plasticizer and 100 parts of a filling agent. The preparation method comprises the following steps: preparing shell fabric slurry; preparing base material slurry; applying the obtained shell fabric slurry to release paper, and drying; applying the base material slurry to a surface layer, and foaming at the temperature of 180-190 DEG C; uniformly applying the bonder to a foaming layer, and bonding the base cloth with the foaming layer; drying an obtained product at the temperature of 140-170 DEG C to prepare the leather. According to the preparation method, the surface properties of the leather are improved and the leather is good in wear resistance, odor-free and good in smooth feel.

Description

technical field [0001] The invention relates to an artificial leather and a manufacturing method thereof. Background technique [0002] As a substitute for natural leather, artificial leather has a wide range of applications in various fields. However, among most of the leathers currently available on the market, the wear resistance of the leather is poor, and the contact surface used to contact the human body has poor smoothness. [0003] The sofa leather on the market is mainly composed of resins, plasticizers, fillers, adhesives and other materials. In the primer: 100 parts by weight of resin, 80-90 parts by weight of plasticizer, 140 parts by weight of filler and adhesive (polyurethane). [0004] The use of plasticizers in the formulation of leather products will affect the flexibility of the leather. Although a large amount of plasticizers will make the leather more flexible, it will also make the leather feel sticky and the smoothness is not good enough, resulting in...

AI Technical Summary

Problems solved by technology

[0004] The use of plasticizers in the formulation of leather products will affect the flexibility of the leather. Although a large amount of plasticizers will make the leather more flexible, it will also make the leather feel sticky and the smoothness is not good enough, resulting in poor surface physical properties of the product. Reduced physical strength

[0005] In addition, the existing technology uses polyurethane as an adhesive, and the leather products produced have a heavy odor and volatile harmful gases. Getting a bad impression is not good for leather products to occupy the commercial market
