Embodiment 1

[0032] Such as Figure 1-3 As shown, a new type of high refractive index coating hybrid material, including optical coating material, said optical coating material is composed of zirconia, titanium oxide and other additives, said zirconia includes ZrO2 , the titanium oxide includes TiO 2 , said its additives include titanium powder, because titanium oxide and zirconium oxide cannot reach 100% purity, containing impurities such as Co, Mn, Ni, Cu, Al, Pb, Fe, and Si, these impurities are in the form of oxides It exists in the material, which affects the refractive index of the film. For example, the refractive index of aluminum oxide is 1.7, and the projection wavelength range is between 170-6500nm. It is necessary to add other additives to reduce and remove impurities to avoid the impact of impurities on the film material. The ZrO 2 50-99.5wt%, TiO 2 0.5-50wt% and metal titanium powder 0-20wt%, titanium oxide and zirconium oxide have strong light absorption ability even in th...

Embodiment 2

[0034] Such as figure 2 and image 3 As shown, the production process of a new type of high refractive index coating hybrid material includes the following steps:

[0035] Sp1: Put the obtained transparent solution as the precursor of the hydrothermal reaction into the activated dialysis bag for 5-6 times of dialysis, and the external solution is ionic water until the pH of the solution is close to neutral, and remove an appropriate amount of silver nitrate solution to detect the residual Chloride ions;

[0036] Sp2: Put the dialyzed gel in a 50mL pair of autoclave, put it in a blast oven at 170-230°C for 15-24h, and prepare Zr-Ti-O composite nanocrystals by hydrothermal reaction;

[0037] Sp3: After freezing the obtained product at a low temperature of -20°C for 24-48 hours, place it in a freeze dryer for vacuum freeze-drying to obtain dispersed Zr-Ti-O composite nanopowder;

[0038] Sp4: granulation, put the Zr-Ti-O composite nanopowder into the swing granulator, add the...

Embodiment 3

[0042] When configuring the pre-solution, the three raw materials of zirconia, titanium oxide and metal titanium powder can be mixed, and then the mixed raw materials can be put into the 3D mixer, and at the same time according to the TiO 2 50-100w%, 20-50w% zirconia, 0-20w% titanium metal powder, put into the auxiliary group of grinding balls with different diameters to mix, mix at a speed of 5-30r / min for 2-5 hours, and then configure Good ZrOCl 2 solution and prepared TiCl 4 The hydrochloric acid solution is mixed in a ratio of 1:4, and then slowly dripped into the configured L-arginine solution. With the addition of the precipitant, it is mixed with the raw materials in the above-mentioned 3D mixer in the reaction vessel, and magnetically The stirrer was stirred at room temperature for 13 hours, and the stirring was stopped after the reaction was complete, and the obtained stock solution was subjected to gelation treatment.

[0043] After the gel treatment is completed,...

Abstract

The invention provides a novel high-refractive-index coating mixed material and a production process thereof and relates to the field of optical coating materials. An optical coating material is included; the optical coating material is composed of zirconium oxide, titanium oxide and other additives; the zirconium oxide comprises ZrO2; the titanium oxide comprises TiO2; the additives comprise titanium powder; and the ZrO2 accounts for 50-99.5 wt%, the TiO2 accounts for 0.5-50 wt%, and the metal titanium powder accounts for 0-20 wt%. Manufacturing is completed through burdening, granulation, smelting and split charging, Ti is adopted to replace part of the TiO2 in an original formula, the Ti can capture redundant oxygen in the TiO2 in the material production process, a Ti3O5 structure morestable in vacuum is generated, the Ti3O5 and the ZrO2 are mutually dissolved in the sintering process, and generated Zr-Ti oxide is more stable in vacuum and smaller in gas release amount. Compared with an old product, the novel high-refractive-index coating mixed material has the advantages that the pre-melting time can be remarkably shortened, the production speed can be increased, the materialuse cost can be reduced, meanwhile, the gas release amount is reduced, splashing is reduced, point defects caused by splashing on a thin film can be reduced, and the yield can be increased.

Description

technical field [0001] The invention relates to the field of optical coating materials, in particular to a novel high-refractive-index coating mixed material and a production process thereof. Background technique [0002] Both titanium oxide and zirconium oxide are semiconductor materials with superior performance. They can not only improve the mechanical strength of the catalyst, but also have co-catalysis and catalytic effects. Nano has broad application prospects in photocatalysts, sensitive devices, solar cells and other fields and value, and also has excellent optical properties. In the application field of catalyst carrier, due to the relatively small specific surface area of ​​titanium oxide and zirconium oxide, the thermal stability is slightly insufficient. If it is used in a working environment for a long time, it is easy to change the crystal form, thereby affecting the activity of the catalyst. The service life of the catalyst is limited. In order to improve the...
