Problems solved by technology

[0004] Traditional nano-titanium dioxide can play a photocatalytic purification effect only under the action of ultraviolet light. It has a weak effect on the long-lasting high-concentration pollution gas in the car. It is obviously powerless to purify the air to reach the standard. Therefore, the air self-circulation system in the vehicle To produce high requirements for purification, it is not suitable for
[0005] At present, some chemical reagents are popular in the market to cover up the technology of odor stimulation in the car, but these palliatives do not cure the root cause, they only temporarily cover the smell, the pollutants are not removed, but will increase some new pollution, which will affect the air quality in the car Security and Governance Purging Doesn't Help

Embodiment

[0093] The present invention will be further described below in conjunction with specific examples, but they should not be construed as limiting the protection scope of the present invention.

[0094] Reference Example 1: Preparation of nano-titanium dioxide A doped with ferric oxide semiconductor

[0095] At room temperature, 49 grams (0.3mol) of ferric trichloride (Beijing Chemical Materials Co., Ltd.) was dissolved in 1000 ml 5% (weight / volume) of NH 4 OH aqueous solution. Then, 0.6 mol of industrial-grade titanium tetrachloride (Tianjin Chemical Plant) was slowly added dropwise into the aqueous solution in a frozen water bath, and a white precipitate was uniformly produced under uniform stirring. Then add 0.15mol perchloric acid (Beijing Second Chemical Factory) under stirring to dissolve the white precipitate and obtain a transparent liquid. The liquid was evaporated by heating at 95°C for 2 hours to remove excess water and obtain a sol-gel. The resulting sol-gel was f...

[0098] Reference Example 3: Preparation of nano-titanium dioxide C doped with zinc oxide semiconductor

[0099] Dissolve 19 g (0.15 mol) of zinc nitrate (Beijing Chemical Materials Co., Ltd.) in 1000 ml of 5% (weight / volume) NH at room temperature 4 OH aqueous solution. Then, 0.6 mol of industrial-grade titanium tetrachloride (Tianjin Chemical Plant) was slowly added dropwise into the aqueous solution in a frozen water bath, and a white precipitate was uniformly produced under uniform stirring. Then, 0.15 mol of nitric acid (Beijing Chemical Raw Material Company) was added under stirring to dissolve the white precipitate and obtain a transparent liquid. The liquid was evaporated by heating at 95°C for 2 hours to remove excess water and obtain a sol-gel. The resulting sol-gel was filtered and washed 4 times with 500 ml of water to bring its pH to 7. The washed sol-gel was dried at 20° C. and 10 mmHg for 5 hours to obtain a white micropowder, which is a metastable titanium di...

Embodiment 1

[0102] According to the mass ratio, take by weighing 47% by weight of pyrolusite powder clay (purchased from Shandong Zibo Zhaoyi Industrial Co., Ltd.), 45% by weight of nano-titanium dioxide A and 8% by weight of activated carbon (purchased from Beijing Kecheng Guanghua New Technology Co., Ltd. Co., Ltd.), under stirring at a speed of 200r / min, add deionized water based on the total weight of 40% by weight of pyrolusite powder clay, nano-titanium dioxide A and activated carbon, mix uniformly, and granulate into small spherical particles. Bake at 100°C for 70 minutes, then raise the temperature to 550°C at a rate of 3°C / min, keep at this temperature for 0.5h, and then sinter to obtain composite particles A1.

[0103] The XRD pattern of the composite particles is shown in Figure 4 , the comparison chart of the intensity of hydroxyl radicals detected by ESR between composite particles A1 and nano-titanium dioxide A raw materials is shown in Figure 5 .

Abstract

The invention relates to a purification component comprising an air purification material for automobile interior air purification. The air purification material is prepared by a method comprising the following steps: uniformly mixing, granulating, drying and calcining a solid mixture containing the following components in the presence of an adhesive water: (1) 40 to 56 weight percent of semiconductor material-doped nanometer titanium oxide, (2) 42 to 50 weight percent of pyrolusite powder-containing clay, and (3) 2 to 10 weight percent of activated carbon. The invention further relates to an automobile interior air purification device comprising the purification component, use of the air purification material for production of the purification component and the purification device and use of the purification component for production of the purification device. According to the air purification material, the volatilization time of a TVOC (total volatile organic compound) can be effectively shortened, the air can be effectively purified, and the effects can be achieved even without light; the purification material also has sufficient strength, so that the air purification time is greatly prolonged.

Description

technical field [0001] The present invention relates to an air purification assembly for air purification in a car comprising an air purification material and an air purification device comprising the assembly, and the present invention also relates to the use of the air purification material in the production of the air purification assembly and the air purification device Use and use of the air cleaning assembly in the production of the air cleaning device. Background technique [0002] Due to the continuous and long-term release of toxic and harmful gases from the interior decoration materials, the harmful gases generated by the engine combustion, the harmful gases introduced into the car by the air-conditioning system, and the growth of bacteria and molds, the car, especially the new car, will be filled with strong volatile gas. Harmful gases such as sexual organic matter and odor. The airtightness of the car is good, the ability of the air to dilute pollutants is very ...
