Abstract

The invention provides an SEBS rubber additive, a preparation method and the SEBS rubber thereof. The SEBS rubber additive comprises the following components in weight percentage: 25-30% of hexadecane, 20-25% of heptadecane, 15-20% of pentadecane, 10-15% of octodecane, 10-15% of tetradecane, 2-5% of tridecane, and 2-3% of dodecane. When the SEBS rubber additive and the SEBS together form the rubber and a thermoplastic elastomer, the diluted smell generated at a high temperature is removed. Meanwhile, the odor is eliminated.

Description

technical field [0001] The invention belongs to the field of SEBS rubber, and in particular relates to an SEBS rubber additive, a preparation method and SEBS rubber thereof. Background technique [0002] Natural rubber, as a renewable natural resource with superior comprehensive performance, has the characteristics of high elasticity, high strength, high elongation and wear resistance, and is widely used in aerospace, national defense, heavy vehicles, aircraft tires, medical elastic body. It occupies a very important position in the national economic construction. In recent years, the price of natural rubber in the international market has remained high, which has overwhelmed most of my country's high-consumption, labor-intensive and low-tech product companies. In order to cope with this severe situation, it is necessary to strengthen research on new processes, apply high-tech, and develop high-performance composite materials. The processing method of composite materials ...
