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第一阶段项目将专注于开发热活化交叉交联热塑性粘合剂薄膜。尽管有许多热塑性粘合剂膜可用，但没有一种能够在施加时交联。交联官能度的添加将允许由此产生的粘合接头在更高的温度下使用，更接近原始膜熔点，而不会由于粘合剂的软化或蠕变而损失性能。 开发交联粘合剂膜的主要应用是将聚丙烯复合材料蒙皮粘合到泡沫芯上，用于制造结构夹层板。新的粘合剂膜将允许在足够低的温度下粘合，以避免对泡沫的损坏，同时使面板能够在接近膜施加温度的温度下使用，从而扩展面板可以使用的温度范围。这将大大拓宽这些轻质夹层板在运输和基础设施应用中的应用范围。此外，交叉粘合剂膜在其他领域具有潜在用途，包括服装和汽车内饰，其中更耐用、更高温度的粘合是有价值的。
