AI Technical Summary
In the existing technology, the application of montmorillonite in rubber composites has problems such as large amount of intercalating agent, long mixing time, high energy consumption, decreased mechanical properties and insufficient air tightness, which limit its application in polymer composites.
By using carbon black and montmorillonite as a co-reinforcing agent and employing in-situ intercalation technology to control the proportions of intercalating agent and montmorillonite within a suitable range, and combining this with stearic acid to improve dispersibility, rapid intercalation modification is achieved, resulting in the preparation of rubber nanocomposites with excellent mechanical properties and airtightness.
Rapid preparation of rubber nanocomposites has been achieved, which improves the mechanical strength and airtightness of the materials, shortens the process flow, reduces energy consumption and emissions, and significantly enhances mechanical and airtight properties.
