Title:
STACK OF LAMINATIONS AND METHOD FOR THE PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/135378
Kind Code:
A3
Abstract:
The stack of laminations consists of punched laminations (5), which are bonded together by an adhesive agent. The adhesive agent is composed of an adhesive (4) and an initiator (15), which consists of methacrylates, derivative imines and methacrylic esters. The completely cured adhesive bond has long-term resistance when exposed to a temperature of at least over 80°C. The adhesive (4) is applied over the full surface area and in a contacting manner to one side of the lamination (5) and the initiator (15) is applied to the same side and/or to the other side of the lamination (5). The initiator (15) reacts with the adhesive (4) when contact is made and establishes the adhesive connection between laminations (5) lying against one another. The adhesive agent may, however, also be an adhesive (4) that cures by itself when heat is applied.
