Networked Silicone Mechanical Strength via Hindered Crosslinking

The patent creates a composite network structure by combining organopolysiloxane chains with crosslinking agents forming siloxane bonds. This composite approach integrates the thermal and oxidative stability of silicones with enhanced mechanical strength through the crosslinked network, resolving the contradiction between maintaining optical stability and improving mechanical properties

The patent modifies the chemical structure parameters of silicone networks by introducing specific crosslinking agents and controlling crosslinking density. By changing the molecular architecture from linear to crosslinked networks and adjusting crosslinking parameters, the patent simultaneously improves mechanical strength while preserving the optical stability characteristic of silicones

The patent replaces the mechanical reinforcement approach (adding physical fillers that scatter light) with a chemical reinforcement approach (forming molecular-level crosslinks). This substitution achieves mechanical robustness through covalent bonding in the polymer network rather than through physical filler addition, thereby maintaining optical transmission properties

The patent applies reinforcement at the molecular level through crosslinking rather than adding macroscopic fillers. The crosslinks are distributed locally throughout the polymer chains, providing mechanical strength without introducing light-scattering particles that would compromise optical transmission
