Heteropolyacid air bactericide as well as preparation method and application thereof

Abstract

The invention relates to the technical field of disinfectants, in particular to a heteropolyacid air bactericide as well as a preparation method and application thereof. The heteropolyacid air bactericide provided by the invention is prepared from the following raw materials in parts by weight: 1-5 parts of N, N-dimethylformamide, 1.5-5 parts of propionic acid, 2.5-3 parts of heteropolyacid, 3-10 parts of a coupling agent, 10-30 parts of chlorine dioxide and 30-45 parts of water. The heteropolyacid air bactericide has the following beneficial effects: (1) the catalytic performance is controllable, and the catalyst design is facilitated; (2) the heteropolyacid air bactericide is easily soluble in water and an organic solvent, can be loaded on substances such as silica gel or activated carbon, shows very high catalytic ability and selectivity, and can be used for homogeneous and heterogeneous catalytic reaction systems; (3) the stability is better, and the continuous and efficient sterilization can be realized; and (4) safety and greenness are achieved, and the bactericidal effective components are harmless to human bodies.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a heteropolyacid air sterilant and its preparation method and application. Background technique [0002] Air is an important transmission route for microorganisms such as bacteria and viruses. In our work and living places, we are always facing the dangers of bacteria and viruses in the air. The new coronavirus that has ravaged the world this year is an example of airborne viruses. Therefore, in order to effectively avoid the spread of related diseases, it is necessary to effectively kill microorganisms such as bacteria and viruses in the air. [0003] Existing air sterilization technologies have certain deficiencies in use: for example, [China Invention] CN201810776498.9 discloses an air sterilization device for intensive care units, which uses negative ions to sterilize air, but the effect of negative ion air sterilization is not obvious, and negative ions are The reside...

Problems solved by technology

[0003] Existing air sterilization technologies have certain deficiencies in use: for example, [China Invention] CN201810776498.9 discloses an air sterilization device for intensive care units, which uses negative ions to sterilize air, but the effect of negative ion air sterilization is not obvious, and negative ions are The residence time in the air is short, and it only stays for a few seconds in places with a lot of dust, and negative ions are generated by high-voltage discharge, which often produces a large amount of ozone at the same time, causing damage to the human respiratory system; [Chinese Invention] CN202010382776.X discloses a A photocatalyst air sterilization disinfectant and its application, the photocatalyst air sterilization mainly uses ultraviolet light to irradiate the photocatalyst to produce effects, and ultraviolet rays are harmful to the human body; [Chinese invention] CN201910329921.5 discloses an air sterilization purifier, which uses activated carbon The adsorption principle carries out the sterilization process, but the activated carbon can only adsorb temporarily, and as the temperature and wind speed increase, the adsorbed pollutants may be freed, so the filter material should be replaced frequently to avoid adsorption saturation
