Rare earth elements are known as strategic elements and a treasure trove of new materials in the 21st century. The new multifunctional additives prepared by using rare earth compounds have significant effects in improving the comprehensive properties of silicone rubber and giving it new functions, and because of its high efficiency and environmental protection, it solves the problems of low efficiency and environmental pollution of existing additives. question. At present, rare earth functional additives are mostly rare earth inorganic compounds. Taking advantage of the characteristics of rare earth elements that are easy to form complexes, the development of diverse rare earth organic functional additives will become a research hotspot in the future. The emergence of rare earth functional additives has expanded the application scope of polymer materials additives and has huge market potential.
