汽车玻璃密封材料对车体的密封剂粘合牢度的搭接剪切测试

[中文适用范围]： 本推荐规范定义了一种构建搭接剪切试样的程序，用于测试汽车密封胶粘合剂与用于汽车封装的弹性体材料之间的粘合性。当前汽车玻璃封装的做法描述为使用热塑性或热固性材料将弹性体材料模塑到玻璃的外边缘，该材料在模具中迅速固化。玻璃从模具中取出时，固化的弹性体材料已粘合到玻璃的周边。这种封装玻璃模块现在可以使用密封胶粘合剂粘合到车身的开口中。 [外文原描述]： This recommended practice defines a procedure for the construction of a lap shear specimen for the purpose of testing the bondability of an automotive sealant adhesive to the elastomeric material used in automotive encapsulating.The present practice of encapsulating automotive glass is described as molding elastomeric material onto the outer edge of the glass using thermoplastic or thermosetting material that quickly sets in the mold. The glass is removed from the mold with cured elastomeric material bonded to the perimeter of thee glass. This encapsulated glass module can now be bonded with a sealant adhesive into the body opening of a vehicle.Cross Reference: ASTMD1002
