AI Technical Summary
Existing tensile bars are prone to peeling when testing the adhesion of silicone printing, affecting the accuracy of the test results and failing to effectively bond the silicone printing.
The design employs a tension strip comprising a polyurethane base layer, a first adhesive layer, and a second adhesive layer. The first and second adhesive layers are composed of component A and component B. Component A includes polyurethane oligomers and chlorinated polyolefin resin, while component B includes an oil-based isocyanate curing agent. The adhesive is formed by hot pressing. The softening temperature of the chlorinated polyolefin is 65-75℃. Hydrofluoric acid and silicate are added to the second adhesive layer to enhance the bonding strength.
This improves the adhesion strength between the silicone print and the test tensile strip, reduces the breakage and peeling of the tensile strip, and ensures the accuracy and reliability of the test.
