With the extensive use of rubber products, the problem of waste rubber pollution is becoming more and more serious. On the 11th, it was learned from the College of Chemistry and Chemical Engineering of Yangzhou University that teachers and students of the college used a new technology to reuse waste tires, which is not only environmentally friendly but also a substitute for natural rubber products.
The new technology researched by teachers and students of the College of Chemistry and Chemical Engineering revolves around the high-quality green recycling of waste rubber, focusing on the development of key technologies for the green compounding of waste rubber to prepare magnetic and wave-absorbing elastomer materials, and the clever use of magnetic ferrite as a functional body The particle or modified ferrite particle itself absorbs the microwave, and under the microwave-assisted condition, it simultaneously realizes the desulfurization activation of the rubber powder and the in-situ modification of the surface of the magnetic ferrite particle, which solves the secondary molding vulcanization and organic-inorganic The problem of interfacial compatibility of the compound, the green compounding of the rubber powder was achieved under the condition of no or very few additives, and the functional elastomer composite material was successfully prepared.
