China FAW Automotive Co., Ltd. is developing silicone leather

China FAW Automobile Corporation’s latest patent layout in the field of silicone leather has attracted widespread attention from both the industry and the market.

According to information disclosed by the National Intellectual Property Administration, FAW has applied for a project titled “A Silicone Polymer.” finished leather and its preparation method” (Publication No.: CN121428838A, publication date: January 30, 2026). The core innovation of this patent lies in introducing modified nano-molybdenum disulfide into organosilicon synthesis finished leather The adhesive layer in the surface layer significantly enhances the bond finished leather wear resistance, toughness, and surface lubrication performance.

In the current combination finished leather In the material system, organosilicon is combined finished leather It holds an important position due to its unique comprehensive performance advantages. These materials use liquid silicone rubber as the main raw material, with no release of harmful small molecules during production, highly aligning with the trends of green manufacturing and sustainable development, and offering outstanding competitive advantages in increasingly stringent environmental regulations. In addition, silicone is combined finished leather Inherently possessing excellent weather resistance, low volatility, easy cleaning, and a comfortable touch, these features enable it to meet the basic application needs of automotive interiors, high-end consumer goods, and other scenarios, laying a solid foundation for future performance enhancements and upgrades.

Nevertheless, in some key mechanical performance indicators—especially wear resistance—existing silicone compounds are available finished leather There is still room for continuous improvement. The patent FAW has submitted this time is precisely an effective solution to this performance bottleneck.

The patent abstract shows that this invention belongs to the category of organosilicon polymers finished leather In the technical field, a type of organosilicon polymer has been disclosed finished leather and its preparation method, including an organic silicone surface adhesive layer and an organic silicone base adhesive layer from top to bottom. By mass percentage, the silicone surface adhesive layer consists of 510% hydrogen-containing silicone oil, 5% color paste, 0.0010.01% catalyst, 0.010.05% inhibitor, and the remainder is a base adhesive mixture containing modified molybdenum disulfide; The silicone base layer includes 35% hydrogen-containing silicone oil, 15% tackifier, 0.0010.01% catalyst, 0.010.05% inhibitor, and the remainder is a base adhesive mixture without modified molybdenum disulfide.

Step 1, Preparation of the silicone surface adhesive layer: Add the base adhesive mixture containing modified nano molybdenum disulfide, hydrogen-containing silicone oil, color paste, catalyst, and inhibitor to the internal mixer according to the mass percentage in the formula. After mixing evenly, the silicone surface adhesive layer is obtained;

Step 2, Silicone Primer Layer: Add the base adhesive mixture without modified nano molybdenum disulfide, hydrogen-containing silicone oil, tackifier, catalyst, and inhibitor to the mixer according to the mass percentage in the formula, mix evenly to obtain the organosilicon primer layer;

Step 3: Silicone combination finished leather Preparation: First, apply silicone topcoat to the release paper, apply to a thickness of 100μm, and bake in a 150°C oven for 5 minutes to cure; Then apply the silicone base layer to a thickness of 100μm, bake in a 100°C oven for 5 minutes to cure; Apply the silicone base layer again to a thickness of 100μm, bond the base cloth to the silicone base layer, and bake in a 150°C oven for 3 minutes; Finally, peel off the release paper to obtain the aforementioned silicone compound finished leather.
