Curing Accelerator Composition for Cyanoacrylate Adhesives

The patent applies preliminary action by incorporating a polymer component into the cyanoacrylate composition before use. This pre-added polymer acts as a stabilizer that prevents premature polymerization during storage, allowing the highly reactive monomer to maintain its curing speed without compromising storage stability. The polymer remains dormant until the adhesive is applied and triggers polymerization through environmental factors.

The patent applies parameter changes by modifying the chemical composition parameters of the curing accelerator system. Instead of using traditional highly irritating accelerators, the invention introduces a polymer component with specific molecular weight and composition that changes the acceleration mechanism. This new parameter regime achieves curing acceleration through a different chemical pathway that does not rely on irritating substances, thus maintaining curability while reducing irritation.

The patent applies the intermediary principle by introducing a polymer component that acts as a mediator in the curing process. This polymer intermediary facilitates the curing acceleration function while preventing the direct contact between traditional irritating accelerators and the adhesive system. The polymer mediates the chemical reactions to achieve rapid curing without generating whitening or irritation, thus decoupling the acceleration function from harmful effects.

The patent applies this principle by using a polymer component that serves as a temporary, consumable element in the curing process. This polymer is designed to be consumed during the curing reaction, providing the necessary acceleration and then degrading or integrating into the cured structure without leaving harmful residues. This disposable polymer intermediary enables fast curing on sensitive substrates like engineering plastics without causing erosion or cracking, as it does not remain as a harmful substance after curing.
