Abstract

The invention provides a rubber composite material, which comprises 0.5-5 wt% of tombarthite sulfide, and further provides a preparation method for the rubber composite material. The preparation method comprises the following steps: mixing the tombarthite sulfide and rubber; conducting plastication, mixing and sulfidation forming to obtain the rubber composite material. The prepared rubber composite material is provided with relatively excellent stretching property, simple and safe in manufacturing technology, easy to operate, and relatively low in preparing cost and energy consumption, so as to facilitate industrialized production; besides, the tombarthite sulfide is adopted as a green rubber ingredient, so as to be free from contamination to environment, and environmental-friendly.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a rare earth sulfide rubber additive and a preparation method thereof. Background technique [0002] Rubber is a high-molecular compound with high elasticity. It has become an important material due to its special properties such as excellent fatigue resistance, high wear resistance, electrical insulation, compactness, corrosion resistance, high temperature resistance and low temperature resistance. industrial materials. With the continuous growth of the global automobile industry, high-speed railway and aerospace and other industrial fields, the demand for rubber products will continue to be strong, and the rubber industry will maintain a continuous development trend. [0003] Rubber additives are important raw materials in the rubber industry. Rubber additives play a pivotal role in improving the processing and application performance of rubbe...
