Problems solved by technology

[0008] In principle, the sealing agent blocks the source of the release of volatile organic compounds, which should be able to completely eliminate the pollution pathways of volatile organic compounds. Avoid wear and tear, and after a period of time, the original sealant will lose its original effect
However, there is a problem of elimination effect in the methods of using elimination agent and capture agent. Although the pollution can be reduced to a certain extent, because the pollution of the indoor environment is affected by many factors such as pollution degree, temperature, and air circulation, the elimination reaction is often difficult. Thoroughly, it is difficult to achieve the desired effect of eliminating volatile organic compounds

[0035] Preparation of bismuth vanadate

[0036] Dissolve 0.0015 mol of sodium vanadate and 0.006 mol of bismuth nitrate in deionized water respectively, drop the sodium vanadate solution into the bismuth nitrate solution drop by drop, stir for 30 minutes, let it stand for 5 hours, and put it in a constant temperature drying box After reacting at 160 degrees Celsius for 12 hours, after cooling to room temperature, continue to keep stirring and add 0.01 mol of hydrogen peroxide, filter with suction, wash and dry to obtain bismuth vanadate powder.

[0037] At room temperature, 8 parts by weight of niobium pentachloride were dissolved in 100 parts by weight of absolute ethanol to obtain a niobium pentachloride ethanol solution, which was left to stand for 15 minutes; 15 parts by weight of bismuth vanadate, 0.08 parts by weight of sulfurous acid Sodium hydrogen blocked HDI was added to the ethanol solution of niobium pentachloride, and the mixture was uniform to obtain the first mi...

Embodiment 1

[0039] In the container, dissolve 5 parts by weight of polyvinyl alcohol 2488 and 0.8 parts by weight of carbomer in 100 parts by weight of water; add 0.08 parts by weight of mesoporous silicon (Shanghai carboxyphenanthrene, MSNs-90) into the container, and Raise the temperature to 55 degrees Celsius and keep it for 24 hours; cool to normal temperature, add 2 parts by weight of imidazolidinone and 0.04 parts by weight of nano-modified niobium oxide photocatalytic oxidant, mix well, adjust the pH value to 7, and obtain a slow-release gel.

Embodiment 2

[0041] In a container, dissolve 2 parts by weight of polyvinyl alcohol 2488 and 0.6 parts by weight of carbomer in 100 parts by weight of water; add 0.05 parts by weight of mesoporous silicon (Shanghai carboxyphenanthrene, MSNs-90) into the container, and Raise the temperature to 55 degrees Celsius and keep it for 24 hours; cool to normal temperature, add 2 parts by weight of imidazolidinone and 0.05 parts by weight of nano-modified niobium oxide photocatalytic oxidant, mix well, adjust the pH value to 7, and obtain a slow-release gel.

Abstract

The invention relates to a green environment-friendly mesoporous silicon nano sustained-release gel capable of quickly and high-effectively removing organic pollutants. The sustained-release gel is composed of, by weight, 100 parts of water, 2-8 parts of polyvinyl alcohol, 0.1-1 part of Carbomer, 1-3 parts of imidazolidone, 0.01-0.1 parts of mesoporous silicon, and 0.01-0.1 parts of a photo-catalytic oxidizing agent. The photo-catalytic oxidizing agent has function of catalytic oxidization under ultraviolet, infrared and visible lights. The sustained-release gel can durably and high-effectively remove the organic pollutants in indoor air.

Description

technical field [0001] The invention relates to a green and environment-friendly mesoporous silicon nanometer slow-release gel that can quickly and efficiently remove organic pollutants. Background technique [0002] Through research, it is found that the main way to cause indoor air pollution is a large number of decorative materials and furniture used in the home, mainly including plywood, blockboard, particle board and other artificial boards for interior decoration. Since most of the adhesives used in the production of decorative panels are urea-formaldehyde resins, the residual volatile organic components in the panels will gradually be released into the air, becoming the main source of volatile organic gas pollution in the indoor air, and the released volatile organic compounds Sexual organic gas will also gradually accumulate in walls, floors, and even children's toys, causing great harm to the human body, especially young people. In addition, other various decorativ...
