After curing the adhesive for 1d, test the shear strength at room temperature after soaking in different media for 30 days. See Table 7:
As can be seen from Table 7, the adhesive is excellent in media resistance.
3.3 Adhesion to Different Materials
4 Conclusion
The adhesive uses epoxy resin modified by hydroxyl-terminated silicon-boron resin to improve the heat resistance of the host resin; and the self-made high-activity heat curing agent B is coordinated with the low-molecular polyamide to cure, and an appropriate accelerant is added, so that the system can Slightly lower than room temperature, the curing is complete; the mixed heat-resistant filler activated by the coupling agent has a prominent effect on improving the ablation resistance of the adhesive. The adhesive is cured at room temperature and reaches its maximum strength for a long period of time. It has excellent heat resistance, especially excellent heat aging resistance, has a certain degree of toughness, and has good adhesion to a variety of materials. Can be widely used in aviation, aerospace structural parts bonding.
