The intellectual property information shows that Suzhou Rui High-tech Materials Co., Ltd. has obtained a project entitled "an organic silicon foamed composite automotive leather and its preparation method", authorized notice No. CN118127834B, the application date is May 2024.

The patent abstract shows that the application relates to the technical field of synthetic automotive leather, and specifically discloses an organic silicon foam composite automotive leather and its preparation method. The invention relates to silicone foamed composite automotive leather, which comprises a substrate layer, a polyurethane layer, an organic silicon layer and a printing layer. The organic silicon layer comprises a first coating and a second coating, and the second coating is arranged near the polyurethane layer; The first coating is made from the following materials: Dow silicone LCF‑8800A; Dow Silicone LCF 8800B; Stuffing; The second coating is made of the following raw materials: Dow silicone LCF‑8300; Dow Silicone LCF‑8500; Foaming powder PG10; Stuffing; The polyurethane layer is made from the following raw materials: Huafeng dry process resin 9212A; Huafeng dry resin BY‑100 crosslinking agent; Huafeng dry process resin BY 300 accelerator; Stuffing. The applied silicone foam composite automotive leather is not easy to have a large loss of joint strength after being stretched under periodic load.
