AI Technical Summary
The existing silicone synthetic leather base material has insufficient adhesion in high-end applications, making it difficult to maintain high adhesion over a wide temperature range and after aging. Furthermore, the traditional substrate surface treatment process has poor stability and cannot meet the durability requirements of high-end fields.
By employing a specific formulation design, including components such as vinyl silicone oil, fumed silica, and calcium carbonate filler, a composite system with high crosslinking density is constructed. Furthermore, through molecular structure design and innovative adhesive system, a high-adhesion underlayer adhesive is prepared.
It significantly improves the bonding strength and abrasion resistance of silicone synthetic leather, solves the problem of weak bonding, broadens the range of high-end applications, and has a simple and environmentally friendly process, making it suitable for large-scale production.
