AI Technical Summary

Technical Problem

The existing silicone material and the substrate film have insufficient interfacial bonding, resulting in insufficient interlayer adhesion stability. It is easy to cause interfacial peeling and lifting, making it difficult to form a stable integrated composite structure. In addition, the substrate supported by the base fabric is soft and not rigid, making it difficult to attach it to the panel on a large area.

Method used

A plastic film layer is used as the polymer film substrate layer, and an organosilicon adhesive layer containing anchoring components is set between the organosilicon layer and the plastic film layer. A continuous cross-linking network is formed by reverse lamination of the release carrier and cross-linking network to improve the interlayer bonding stability.

Benefits of technology

It achieves a reliable bond between the silicone layer and the plastic film layer, forming a stable integrated composite structure suitable for home, building and automotive interiors, and has the effects of stain resistance, weather resistance, soft touch and decoration.
