Problems solved by technology

[0002] Styrene-butadiene rubber material is currently the largest general-purpose synthetic rubber material. Because of its good wear resistance, aging resistance, and water resistance, it can replace natural rubber materials in most occasions. It is mainly used in the tire industry, auto parts, rubber hoses, In the fields of rubber shoes, wire and cable, etc.; the flex cracking resistance of styrene-butadiene rubber material is better, but the crack growth speed is fast, the tear resistance is poor, and at the same time, the strength of styrene-butadiene rubber material is also poor; therefore, a Styrene-butadiene rubber materials with high strength and strong tear resistance are necessary
