Description

Technical Field

[0001] The utility model relates to a cover plate assembly, and more precisely, to a cover plate with thermoelectric performance. Background Art

[0002] Traditional glass cover plates have become difficult to meet the complex requirements of modern electronic devices in terms of functionality, energy efficiency, and environmental adaptability. For example, they do not have thermoelectric performance and are prone to falling off, affecting the performance of the cover plate.

[0003] Chinese invention patent document CN115124253B discloses an antireflection coated optical cover plate with high transmittance, including a glass substrate, and high-transmittance antireflection coating layers are fixedly arranged on two surfaces of the glass substrate respectively; the high-transmittance antireflection coating layer is mainly made of the following raw materials in parts by weight: 60-70 parts of a solvent, 25-35 parts of silica sol, 5-10 parts of multi-layer refraction powder, 1-3 parts of silicon carbide, 1-3 parts of a pore-forming agent, and 1-3 parts of a film-forming auxiliary agent; the multi-layer refraction powder is formed by sequentially coating a high-refractive-index layer with a refractive index n1 of 1.8-2.7 and a low-refractive-index layer with a refractive index n2 of 1.4-1.7 on the surface of a base material; the base material is inorganic glass powder; the high-refractive-index layer is titanium dioxide; the low-refractive-index layer is silica. The thickness of the high-transmittance antireflection coating layer is 210-250 nm. The multi-layer refraction powder is prepared by the following method: Sa. Mix tetrabutyl titanate and ethanol evenly to obtain a premixed solution; Sb. Add the base material to a hydrochloric acid solution, ultrasonically disperse for 10-20 min, then add the premixed solution, stir for 40-60 min, filter, dry, calcine, and cool down. At this time, the high-refractive-index layer is coated on the surface of the base material to obtain a semi-finished product; Sc. Add the semi-finished product to silica sol, ultrasonically disperse for 10-20 min, stir for 60-100 min, filter, dry, calcine, and cool down. At this time, the low-refractive-index layer is coated on the surface of the high-refractive-index layer to obtain the multi-layer refraction powder; wherein, the weight ratio of tetrabutyl titanate, the base material, and silica sol is (1-3):(9-11):(14-16). The silica sol in the raw materials of the multi-layer refraction powder is the same as the silica sol in the raw materials of the high-transmittance antireflection coating layer, and the weight ratio of tetrabutyl titanate, ethanol, and the hydrochloric acid solution is (1-3):(15-25):(75-85), and the mass concentration of the hydrochloric acid solution is 3-5%. In step Sb, the calcination temperature is 600-650 °C and the calcination time is 3-5 h; in step Sc, the calcination temperature is 600-650 °C and the calcination time is 3-5 h. The silica sol is prepared by the following method: Mix ethanol and water evenly, then add tetraethyl orthosilicate and methyltriethoxysilane, stir and mix evenly, then add a catalyst, heat up to 60-70 °C, stir for 3-5 h, and cool down to obtain silica sol; wherein, the weight ratio of tetraethyl orthosilicate, methyltriethoxysilane, ethanol, and water is (9-11):(4-6):(45-55):(15-25), and the addition amount of the catalyst is 2-5 wt% of the total amount of tetraethyl orthosilicate and methyltriethoxysilane. The solvent is isopropanol; the pore-forming agent is polyacrylate; the film-forming auxiliary agent is propylene glycol monomethyl ether acetate.

[0004] However, the base material of this patent is inorganic glass powder. Then, tetrabutyl titanate is used to convert it into titanium dioxide, which is coated on the surface of the inorganic glass powder to form a high refractive index layer. After that, silica sol is used to convert it into silica, which is coated on the surface of the high refractive index layer to form a low refractive index layer. By utilizing the synergistic effect among inorganic glass powder, titanium dioxide, and silica, the usage effect of the multi-layer refractive powder is effectively increased, and the transmittance, acid resistance, and weather resistance of the antireflection coated optical cover plate are further improved. However, this structure cannot solve the thermoelectric performance of the existing coated cover plate. Summary of the Invention
