玻璃与汽车玻璃封装用弹性材料的剥离粘性试验

[中文适用范围]： - 本推荐规范规定了用于确定汽车模块化玻璃中玻璃与弹性体材料粘合性的180度剥离试样的构造和测试程序。该测试方法建议使用模量小于172 MPa的弹性体材料作为封装材料。当前的汽车玻璃封装实践描述为使用热塑性或热固性材料将弹性体材料模压在玻璃外缘，该材料在模具中迅速固化。玻璃从模具中取出时，固化后的弹性体材料粘合在玻璃的周边。该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 and testing of a 180 deg peel specimen for the purpose of determining the bondability of glass to elastomeric material in automotive modular glass. This test method suggests that elastomeric material of less than 172 mpa modulus be used as the encapsulating material. The present practice of encapsulating automotive glass is described as molded-in-place 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 the cured elastomeric material bonded to the perimeter of the glass. This encapsulated glass module can now be bonded with a sealant adhesive into the body opening of a vehicle.Cross Reference: ASTMD1002
