Application of Tackifying Resin in Tire Tread Compound
The new tackifying resin S-7000 has excellent heat and moisture resistance,ensuring significant tackifying effect while maintaining longer viscosity retention time,and its comprehensive application performance is excellent,providing strong support for the development of rubber products and tire manufacturing industry.In the experiment,natural rubber and butadiene rubber are selected as the main materials for making semi steel tire treads,and six sets of formulas are designed with S-7000 dosage as the variable for comparison,and the effects of different dosages of tackifying resin on the comprehensive physical properties of tire tread rubber are analyzed,and the physical and mechanical properties of tire tread rubber before and after aging are compared.Comparative analysis of physical and mechanical properties shows that as the amount of S-7000 in the tire tread rubber increases,the Mooney viscosity gradually decreases,and the burning time and vulcanization time gradually increase;the addition of S-7000 has a certain impact on the physical and mechanical properties such as tensile strength and tear strength of tire tread rubber,when the dosage of S-7000 is 2～4 parts,the comprehensive performance of tire tread rubber is the best;with the increase of S-7000 dosage,the processing performance of tire tread rubber is better than that of blank rubber(without S-7000 added),but excessive dosage can easily cause the rubber to stick to the rollers.
