This SBIR Phase I project will focus on the development of a thermally activated cross-linkable thermoplastic adhesive film. Although many thermoplastic adhesive films are available, none are capable of being cross-linked as they are applied. The addition of the cross linking functionality will allow the bonded joints thus created to be used at a higher temperature, closer to the original film melting point, without loss of performance due to softening or creep of the adhesive. The prime application for the development of the cross-linkable adhesive film is for bonding of polypropylene composite skins to foam cores for the manufacture of structural sandwich panels. The new adhesive film will allow bonding at a sufficiently low temperature to avoid damage to the foam while enabling the panel to be used at a temperature close to the film application temperature, thus extending the temperature range at which the panels may be used. This will significantly broaden the application range for these lightweight sandwich panels in transport and infrastructure applications. Additionally the cross-linkable adhesive films have potential uses in other areas including apparel and automotive interiors where more durable, higher temperature bonds are of value.

该 SBIR 第一阶段项目将重点开发热活化可交联热塑性粘合膜。尽管有许多热塑性粘合膜可供使用，但没有一种在应用时能够交联。交联功能的添加将使由此产生的粘合接头能够在更高的温度下使用，更接近原始薄膜的熔点，而不会因粘合剂的软化或蠕变而损失性能。 开发可交联粘合膜的主要应用是将聚丙烯复合材料表层粘合到泡沫芯材上，以制造结构夹层板。新的粘合膜将允许在足够低的温度下粘合，以避免损坏泡沫，同时使面板能够在接近薄膜应用温度的温度下使用，从而扩大了面板的使用温度范围。这将显着拓宽这些轻质夹芯板在交通和基础设施应用中的应用范围。此外，可交联粘合膜在其他领域也有潜在用途，包括服装和汽车内饰，在这些领域，更耐用、更高温度的粘合具有价值。
