High-compressibility high-recovery PVC artificial leather

Abstract

The invention relates to the field of PVC artificial leather production, and particularly discloses a high-compressibility high-recovery PVC artificial leather. The high-compressibility high-recoveryPVC artificial leather comprises a base fabric, a PVC surface layer and a PVC foaming layer, wherein the PVC surface layer and the PVC foaming layer are bonded on the surface of the base fabric through an adhesive; the PVC surface layer comprises the following raw materials in parts by weight: 100 parts of PVC resin powder, 85 parts of diisodecyl phthalate, 2.5 parts of a heat stabilizer, 0.5 partof sodium perchlorate and 5 parts of POM 351; and the PVC foaming layer comprises the following raw materials in parts by weight: 100 parts of PVC resin powder, 90 parts of diisodecyl phthalate, 40 parts of calcium carbonate, 15 parts of antimony trioxide, 2 parts of a first heat stabilizer, 1 part of an AC foaming agent and 2 parts of a second heat stabilizer. The PVC artificial leather providedby an embodiment of the invention can replace PVC artificial leather required to be used with a sponge, and has good environmental friendliness and good use durability. A bonding layer has low plasticizing temperature and good bonding force.

AI Technical Summary

Benefits of technology

This patented technology describes an improved type of material called polyviny chloride (PVC) which was developed earlier than other materials like rubber or synthetic fibers but no harmful chemicals were released during production. It also includes various technical improvements such as compressing into smaller pieces before being stored at room temperatures without losing its properties over time, improving strength when made from this new formulation compared to previous forms, increasing storage stability under pressure, reducing costs associated with manufacturing processes, enhancing flexibility, etc., resulting in more efficient utilization of resources.

Problems solved by technology

Technological Problem: Current methods involve treatments like embossings that use organic solutions such as methyletherketones (MEK), formaldehydes, cyclohexenoxanes) or other chemical compounds which can be dangerous and cause environmental concerns during disposal processes. Additionally, current techniques require expensive equipment and complicated procedures making them difficult to maintain long term performance over time due to their poor repulpable nature.
