preparation example Construction

[0029] Preparation of Mn-Ni-SBA-15: 1.0Kg triblock surfactant P123 (Aldrich, EO 20 PO 70 EO 20 , M=5800) was dissolved in 22Kg deionized water. Then 15Kg of 4mol / L HCl solution was added, and 2.1Kg of tetraethyl orthosilicate was added under stirring, and kept stirring vigorously for 22h. The mixed solution was transferred to polytetrafluoroethylene In the bottle, crystallize at 100°C for 24 hours, then filter, wash, and dry, and finally roast the dried product at 550°C for 6 hours to remove the template agent, and obtain SBA-15 mesoporous molecular sieve white powder. Dilute 1.0Kg nitric acid Dissolve manganese and 0.1Kg nickel nitrate in 1.0Kg deionized water, add SBA-15 mesoporous molecular sieve, impregnate overnight, dry at 110°C for 12h, then roast in air at 550°C for 5h, and cool naturally to room temperature to obtain Mn-Ni -SBA-15 catalyst.

Abstract

The invention relates to a Mn-Ni-SBA-15 coating material for removing ozone, which comprises organic silicon, Mn-Ni-SBA-15, active gamma-Al2O3, a solvent and an auxiliary agent, wherein the organic silicon is adopted as a base material; the Mn-Ni-SBA-15 is adopted as a catalyst; and the active gamma-Al2O3 is adopted as filler. The coating material is mainly used for removing or eliminating ozone in the air and a gas of a special environment and has the characteristics of high ozone conversion rate under the conditions of high temperature and high airflow, favorable adhesive force, long service life, and the like.

Description

technical field [0001] The invention relates to a coating material with high-efficiency deozonation ability under high temperature, high pressure and large flow conditions, in particular to a deozone coating material containing Mn-Ni-SBA-15 catalyst. Background technique [0002] Ozone in the top layer of the atmosphere is beneficial to human beings, it can effectively absorb harmful ultraviolet radiation, but near the ground, ozone with strong oxidizing properties is harmful to human beings and their living environment, it can not only strongly stimulate human respiratory tract , causing a variety of respiratory diseases, but also an important component of photochemical smog. In recent years, sources of ozone generation such as electrostatic copiers, laser printers, electrostatic precipitators, sterilization cabinets, and other discharged home appliances have posed a great threat to people's health. In addition, the increasing popularity of ozone disinfection machines has ...
