Problems solved by technology

In the bonding layer, which is originally a microcellular foam structure, the fragile parts such as polymer aging and the periphery of the cell are prone to fracture under the action of dynamic mechanics, resulting in a decrease in the bonding strength of the bonding layer and insufficient buckling resistance at low temperatures

Abstract

The invention discloses a production method of anti-cracking leather. The leather comprises a base cloth layer, a PVC foaming layer and a surface modification layer, wherein the PVC foaming layer is arranged between the base cloth layer and the surface modification layer, and the PVC foaming layer is particularly prepared from the following raw materials in parts by weight: 110-130 parts of PVC resin, 80-90 parts of an environment-friendly plasticizer, 3-4 parts of a heat stabilizer, 4-5 parts of a foaming agent, 8-10 parts of filler and 3-4 parts of an ultraviolet absorber. According to the anti-cracking leather, PVC is adopted as a main material and matched with base cloth, the novel environment-friendly foaming agent and the heat stabilizer, a coating calendering attachment method is used, efficient and stable surface performance of the artificial leather is guaranteed, the ultraviolet absorber is added into the PVC foaming layer, therefore the leather has an excellent light aging resistance effect, the peeling strength, the low-temperature buckling resistance and the like after long-term solarization are improved, and the phenomena of peeling, cracking and the like of a productin the daily use process are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of leather production, in particular to crack-resistant leather and a production method thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. In order to meet the increasing environmental protection requirements at home and abroad and the increasing health and safety needs of consumers, synthetic leather has replaced a large number of resources. China has become a major producer of synthetic leather in the world. With the increasing market demand, the gap between supply and demand is increasing. my country's synthetic leather industry is ushering in unprecedented opportunities for development. [0003] As a large user of synthetic leather, automobiles have played an important role in the development of synthetic leather. The high requirements of automotive interiors continue to p...
