On February 2, 2021, BTXT Rare Earth Research Institute and CDYT Advanced Materials Technology Company jointly established China's first rare earth nano thermal insulation slurry production line.
"The rare earth nano thermal insulation material is a new thermal insulation material that has more potential for development in the next few years following the energy-saving glass represented by insulating glass and Low-E glass. It has great market prospects and development space, and will bring huge Economic and social benefits." said Yang Jue, general manager of CDYT.
For a long time, the core technology and intellectual property rights of thermal insulation glass coating materials have been held by developed countries such as the United States, Japan, and Europe. China is still in a blank in the field of thermal insulation glass coating materials. According to Yin Jian, Ph.D. of BTXT Rare Earth Research Institute, the research team has successfully developed rare earth heat-insulating agent preparation technology of less than one hundred nanometers by using the unique electronic structure and physical and chemical properties of rare earths, and prepared a variety of rare earth nano heat-insulating agents and rare earths with different media. Nano thermal powder, etc.
Lu Fei, a senior engineer at BTXT Rare Earth Research Institute, said that the composition of rare earth nanomaterials is due to the local surface plasmon resonance effect (LSPR effect) of rare earth nanoparticles in the rare earth nano heat-insulating agent. The body is uniformly dispersed in each system to form a long-lasting and stable rare earth nano heat insulating agent.
With the application of rare earth nano heat-insulating agents on glass coatings, the product performance indicators are equivalent to or even better than those of foreign products. At the technical level, it has realized "curve overtaking" and filled the gap of China's heat-insulating glass coating materials. Blank, it can completely replace imported products.
It is understood that rare earth nano thermal insulation materials can also be widely used in EVA, PVB, TPU and other interlayer films for laminated glass, coatings, plastics, films, displays, energy-saving windows for construction, automobile windshields, etc. In addition to effectively shielding ultraviolet and infrared rays, they also It has many advantages such as heat insulation, transparency and good weather resistance.
"The rare earth nano thermal insulation material is uniformly dispersed in the EVA film to prepare a rare earth nano transparent thermal insulation film. When the visible light transmittance is 60% to 80%, the infrared blocking rate can reach 80% to 90%. The UV blocking rate is over 99%, and the thermal insulation temperature difference is nearly 8°C." CDYT technical experts said.
