application patent of nano zirconia in various fields

nano zirconia [jr-r50] is not only used in the field of structural ceramics and functional ceramics, but also used to improve the surface properties of metal materials (thermal conductivity, thermal shock resistance, high temperature oxidation resistance, etc.). Using the conductive properties of nano zirconia doped with different elements, it is used in the manufacture of electrodes in high-performance solid-state batteries

stabilized zirconia [jr-r50y1] and [jr-r50y2] have been widely used in solid oxide fuel cells as an ideal electrolyte; In particular, the special structure and properties of nano zirconia have shown broad application prospects in the fields of electronics, metallurgy, aerospace, chemical industry, environment, biology and medicine

1. The invention introduces an energy-saving nano catalyst for automobile exhaust purification. Its components (weight ratio) are: 10 ~ 20g nano aluminum oxide [vk-l30], 5 ~ 10g nano cerium oxide [vk-ce01], 5 ~ 10g nano yttrium oxide [vk-gd01], 2 ~ 8g nano zirconium dioxide [jr-r50], 3 ~ 8g nano cobalt titanate. It is suitable for the tail gas purification of all kinds of motor vehicles. It not only reduces the emission of harmful tail gas, but also saves oil and energy. The tail gas purification rate reaches the national standard IV

2. The invention relates to a nano enamel (enamel). Using nano composite technology, one or more of nano aluminum oxide [vk-l30], nano silicon dioxide [vk-sp30], nano zirconia [jr-r50], nano titanium dioxide [vk-t25] with excellent performance are compounded with traditional enamel glaze to make nano composite enamel glaze; The weight of nanoparticles accounts for 2 ~ 10% of the weight of nanocomposite enamel. The nanocomposite enamel is coated on the base metal and fired to make nano enamel (enamel). Nano enamel (enamel) is modified to give play to the high activity reaction characteristics of nano particles with small size and large specific surface area, so that some shortcomings of traditional enamel are improved and overcome, and its strength is doubled; Under light, it has the photodegradation function of sterilization, self-cleaning and decomposition of harmful substances

3. The invention relates to a thermal conductive insulating film material and a manufacturing method thereof. The composition and weight percentage of the material range from 8-20% cubic boron nitride, 5-10% nano zirconia [jr-r50], 2-10% nano molybdenum disulfide, and 60-85% rubber material, wherein the rubber material is a rubber material that can be rolled or biaxially stretched, Especially polyisobutylene. The manufacturing method of the invention is to weigh the above raw materials according to the proportion, put them into a reaction kettle or a twin-screw extruder, mix them at 150-170 ℃ for 1-5 hours, roll forming, roll temperature 100-250 ℃, working pressure 100-300mpa; Stretch molding: first melt and extrude the sheet or thick film, biaxially stretch the sheet or thick film at 100-150 ℃, and make the film after proper cooling or heat treatment. The thickness of this film material is 0.01 ~ 3mm, the thermal conductivity is 5-20w/MK, and the volume resistance is 0.1 when the insulation property is 20 ℃ × 10↑[5]m~1.7 × 10↑[5]m。
