Silica Tire Tread Compound Without Resorcinol for Heavy Vehicles

The patent removes resorcinol and formaldehyde from the rubber compound formulation, extracting the harmful substances while maintaining the desired adhesion and dynamic properties through alternative compounds and formulations.

The patent converts the harmful resorcinol-formaldehyde system into a beneficial alternative using compounds that provide similar or improved adhesion and dynamic properties without the toxicity and volatility issues, effectively turning a harmful approach into a beneficial one.

The patent extracts resorcinol and formaldehyde from the formulation to improve fuel efficiency while maintaining dynamic properties through alternative compounds that do not negatively impact energy consumption.

The patent changes the chemical composition parameters by replacing resorcinol and formaldehyde with alternative compounds, which alters the physical and chemical properties of the rubber compound to achieve better fuel efficiency while preserving dynamic performance.

The patent creates a composite rubber compound formulation that combines silica with alternative compounds and additives, achieving a synergistic effect that provides both low rolling resistance and sufficient load-bearing capacity for heavy vehicle applications.

The patent adjusts the formulation parameters by replacing resorcinol and formaldehyde with alternative compounds that enhance the load-bearing properties of silica-based treads without compromising the rolling resistance benefits.
