Inorganic Carbonate Additive for Silicone Compression Set

The patent introduces a salt of a cationic organonitrogen compound as an intermediary substance that mediates between the acid-receiving agent and the cross-linking agent. This intermediary forms a complex with the acid-receiving agent, preventing direct interaction between the acid-receiving agent and the cross-linking agent, thereby reducing deterioration while maintaining compression set improvement.

The patent extracts the harmful acid components from the system by using an acid-receiving agent that selectively binds to and removes residual acids from the organohydrogenpolysiloxane synthesis process. This extraction prevents the acids from catalyzing the deterioration of cross-linking agents while still allowing the desired compression set reduction.

The patent uses a salt of a cationic organonitrogen compound as an intermediary that forms a protective complex with the platinum group metal-based catalyst. This intermediary layer prevents direct contact between the catalyst and harmful substances, thereby reducing catalyst deactivation while maintaining the compression set reduction effect.

The patent applies beforehand cushioning by pre-forming a protective complex between the cationic organonitrogen compound salt and the platinum group metal-based catalyst before the harmful effects can occur. This protective layer is established in advance to prevent catalyst deactivation during the curing process.

The patent applies self-service by incorporating the acid-receiving agent directly into the organohydrogenpolysiloxane synthesis process itself. The acid-receiving agent automatically neutralizes residual acids during the synthesis, eliminating the need for separate neutralization steps and maintaining manufacturing simplicity while improving compression set.

The patent performs preliminary action by adding the acid-receiving agent to the organohydrogenpolysiloxane synthesis process before the final product is formed. This preliminary neutralization of residual acids ensures that the compression set is improved from the outset without requiring additional post-processing steps.

The patent uses self-service by incorporating the acid-receiving agent into the synthesis process itself, where it automatically neutralizes residual acids as they are formed. This eliminates the need for separate neutralization steps and complex multi-stage processes, achieving effective compression set reduction without increasing manufacturing complexity.

The patent merges the acid-receiving function with the organohydrogenpolysiloxane synthesis process by incorporating the acid-receiving agent directly into the synthesis. This combination allows simultaneous production of the polysiloxane and neutralization of acids in a single integrated process, avoiding the need for separate neutralization steps.
