Preparation method of negative ion antibacterial adsorption material composition

Abstract

The invention provides a preparation method of a negative ion antibacterial adsorption material composition. The method is characterized in that (a) 13X molecular sieve raw powder accounting for 60 to75 percent of the total mass of the composition, alkali metal oxides accounting for 10 to 20 percent of the total mass of the composition, tourmaline powder accounting for 10 to 20 percent of the total mass of the composition, and the balance of bonding agents and hole expansion agents are proportionally mixed to form mixed powder of a uniform system; (b) the mixed powder is soaked into a water solution of AgNO3, then, ultrasonic concussion is performed to form suspension; next, a NaOH solution is added for regulating pH to 10; a mixed solution is formed. (c) the mixed solution is sealed andheated under the hydrothermal condition; after the separation, sintering is performed at high temperature; crushing is performed to obtain the composition. Compared with the prior art, the preparationmethod provided by the invention has the advantages that the cost is low; for indoor pollution gas, the adsorption capability is realized; the decomposition and desorption prevention performance is also realized; a certain number of negative ions can also be released; the adsorption effect is promoted; beneficial effects are achieved on the human body.

Description

technical field [0001] The invention relates to a negative ion antibacterial adsorption material composition. Background technique [0002] Indoor air pollution is widely present in various closed buildings such as living rooms, and bad indoor air is causing serious harm to human health. The World Environment Conference held in Washington in 1997 pointed out that indoor air pollution is more serious than outdoor air pollution. The problem of indoor air pollution has been highly valued in many countries in the world. Countries such as Europe, North America and Japan have carried out research work on indoor environmental quality since the 1980s. [0003] my country is a country with a high incidence of cancer. A cancer patient appears in almost five minutes. According to a large number of research reports, the toxic and harmful gases produced by interior decoration, furniture, and electrical appliances are the main cause of most cancers. Modern people almost 80-90% of the tim...

[0009] The patent CN201210408096.6 also uses zeolite, but its modification is treated with fluorine silicon. This method enhances the adsorption capacity of benzene and toluene, but the adsorption performance improvement of formaldehyde and radioactive radon is not obvious.

Patent CN201110023219.X provides a metal-organic framework material for adsorbing indoor pollutant gases, which has good adsorption properties for benzene, toluene, formaldehyde, etc., but its synthesis is complicated, expensive, and not universally applicable
