Bactericide and preparation method thereof

Abstract

The invention provides a novel bactericide, which consists of tourmaline, transition metal and / or oxide thereof, and a carrier. The tourmaline is powder of (Na, Ca) (Mg, Fe)3B3Al6Si6(O, OH, F)31, and accounts for 5 to 80 percent by weight of the bactericide; the transition metal and / or the oxide thereof by the weight of the metal elements account for 0.1 to 50 percent of the weight of the bactericide; and the carrier is one or a mixture of titanium dioxide, silicon dioxide, aluminum oxide, zeolite, zinc oxide, ferric oxide, zirconium dioxide, sepiolite, porous ceramics and active carbon. The bactericide does not need to add a power supply or a light source but can kill microbes such as bacteria, virus and mildew in the air, has the characteristics of small resistance, high sterilization speed and no pollution, and can be widely applied to air sterilization for an air purifier, an air conditioner and a concentrated air-conditioning ventilation system.

Description

technical field [0001] The invention belongs to the technical field of environmental electrochemical catalysis, relates to a fungicide and a preparation method thereof, and belongs to a novel electrochemical catalytic oxidation fungicide. Background technique [0002] In recent years, indoor biological pollution in buildings has been paid more and more attention, especially after a series of respiratory infectious diseases occurred on a large scale. The country has issued a series of standards and norms, such as "Indoor Air Quality Standards", "Hygienic Specifications for Centralized Air Conditioning and Ventilation Systems in Public Places" and "Public Places and Facilities Disinfection Management Procedures (Provisional)", etc. Microbiological pollution puts forward clear limit values. In order to meet the limit values ​​stipulated in these regulations and ensure personal safety, it is necessary to purify the biological pollution of the air. [0003] At present, the purif...

AI Technical Summary

Problems solved by technology

[0003] At present, the purification of biological pollution in indoor air mainly adopts the following methods: one is to spray chemical disinfectants, which can achieve the purpose of purification in a short time, but most chemical disinfectants are toxic and should not be used in an environment with people , so it is generally used in static disinfection, that is, it is used in an unmanned state, which has great limitations; the second is to use a purification device with a high-efficiency filter or a high-voltage electrostatic device to remove biological pollution, but Purification devices with high-efficiency filters generally have great resistance and are not suitable for use in centralized air-conditioning and ventilation systems. At the same time, high-efficiency filter materials need to be replaced regularly, which increases the user's cost of use. High-voltage electrostatic devices usually generate ozone, which is a Therefore, the use of this technology is greatly limited; the third is to use photocatalytic oxidation technology, using ultraviolet light emitted by ultraviolet lamps to kill bacteria, the actual measurement effect is relatively slow, and the equipment is too complicated and the cost is too high
