Abstract:
Recently, it is one of a major problems in automotive industry that wrinkles on seat interior occur at detaching between seat covering and padding foam. The purpose of this research is the way to improve heat resistance and adhesion using polyurethane reactive (PUR) of thermosetting plastic material. We compose PUR that makes thin film and non-tacky characteristic on padding foam. We find optimum situation (method and amount) for leather and padding foam. Viscosity and melting temperature are adjusted to coat with amount. 25~30g/m2 are suitable on padding foam unlike traditional method to coat leather above 100g/ m2. We also verified performances of PUR lamination compared to others. As result, peel strength is strongest at 15.4N/30mm. Heat resistance is also excellent with various padding foams. Furthermore we advance an additional jig to match leather and padding foam by low tacky characteristic of PUR. This jig can increase productivity in seat manufacturing process.
