Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If triallyl isocyanurate is used as a curing agent for thermosetting resins, then the curing function is provided, but the compound volatilizes at high temperatures causing equipment contamination and reduced production yield
Solution Approach 1:
The invention changes the chemical structure parameters of the curing agent by introducing a triphenylalkane backbone with allyloxy groups at specific positions. This structural modification raises the boiling point and reduces volatilization at curing temperatures while maintaining the allyl groups necessary for crosslinking reactions with thermosetting resins.
Solution Approach 2:
The compound combines multiple functional groups (allyl groups for crosslinking, triphenylalkane backbone for thermal stability, and ether linkages for flexibility) into a single molecular structure. This composite approach achieves both high-temperature resistance and effective curing function simultaneously.
2Temperature
If existing compounds with allyl groups are used to achieve high heat resistance, then volatilization is suppressed, but dielectric properties are not satisfactory
Solution Approach 1:
The invention optimizes specific positions on the benzene rings by placing allyloxy groups at the 2, 4, and 6 positions (with R1-R6 representing different substituents). This localized arrangement of functional groups achieves the right balance between heat resistance (through the rigid triphenylalkane core) and dielectric properties (through the strategically positioned ether and allyl groups).
Solution Approach 2:
The compound modifies physical and chemical parameters including molecular weight, polarity, and spatial arrangement of functional groups. These parameter changes improve dielectric properties while the triphenylalkane backbone maintains high heat resistance.
