Description

Environment-friendly PVC artificial leather

Technical Field

The utility model relates to a leather technical field specifically is an environmental protection PVC synthetic leather.

Background

In the eighties, expensive leather clothing and leather materials cannot be consumed by general people, and leather-imitated artificial leather is popular once according to market demands and widely applied to clothing and bags. Therefore, the artificial leather clothes and bags imitating leather can be used for filling the street at one time, and the desire of people to wear leather is met. Compared with leather, artificial leather is easy to age and wear, and has harm to human body due to containing a large amount of chemical raw materials, and the clothes made of the artificial leather gradually lose the market due to being not durable until being replaced by other raw materials. Artificial leather is a plastic product similar to leather. The fabric is usually used as a substrate, a layer of resin mixture is coated or attached on the fabric, and then the fabric is heated to plasticize the resin mixture and is rolled, flattened or embossed to obtain the product. Is similar to natural leather and has the characteristics of softness, wear resistance and the like. Depending on the type of the covering, artificial leather for shoes, artificial leather for bags, and the like are used.

In China, people are used to refer to the artificial leather produced by using PVC resin as a raw material as PVC artificial leather, which is called artificial leather for short. The artificial leather in China has been developed rapidly in the past years, but from the whole industry, many problems still exist, such as poor environmental protection level, heavy pollution, low product added value, insufficient innovation capacity and the like of small-scale production enterprises. Because PVC artificial leather has insufficient impact resistance, processability, thermal stability and the like, PVC is required to be toughened and modified, and a large amount of plasticizer is added. Wherein, when the PVC artificial leather is manufactured, the mass ratio of the PVC to the plasticizer is up to 1 (0.8-1.0). At present, the phthalate plasticizer has the largest dosage and the largest variety. Recent studies have shown that: phthalate plasticizer products have toxic and carcinogenic effects when introduced into the human body at high doses. Therefore, developed countries such as Europe and America impose restrictions on the products. With the continuous development of artificial leather manufacturing industry in the world, the environmental protection requirements of people on artificial leather are higher and higher.
