Problems solved by technology

[0005] However, hydrogen peroxide also has certain defects in use, such as poor stability, greater influence by organic matter, and certain drug-resistant strains, which seriously restrict the popularization and use of hydrogen peroxide.
At the same time, in terms of fresh air, hydrogen peroxide is not strong enough to oxidize and decompose some sources of peculiar smell in the car, such as sulfides, nitrogen compounds, and formaldehyde, and it will take a long time to completely eliminate them.

Abstract

The invention relates to automotive air disinfecting and refreshing spray and a process for preparing the same, and belongs to the field of technologies for preparing disinfectants. The automotive air disinfecting and refreshing spray mainly comprises hydrogen peroxide, glutaraldehyde, silver-containing oxidizing agents, protective agents, stabilizers, pH (potential of hydrogen) regulators and the like according to certain proportions. As proved by experiments, the automotive air disinfecting and refreshing spray and the method have the advantages that the shortcomings of low disinfecting efficiency and even deficiency of disinfecting effects of existing automotive disinfectants can be overcome by the aid of the automotive air disinfecting and refreshing spray, compound hydrogen peroxide disinfection liquid capable of quickly killing persisting bacteria in automobiles, purifying air and eliminating peculiar smell sources can be provided, the automotive air disinfecting and refreshing spray is high in efficiency, broad in spectrum, free of residues and secondary pollution and good in stability and is environmentally friendly, the bacteria can be killed quickly, and the like.

Description

technical field [0001] The invention relates to an air disinfection fresh spray for vehicles and a preparation process thereof, which belongs to the technical field of preparation of disinfectants. Background technique [0002] With the improvement of people's living standards, the penetration rate of cars is getting higher and higher, and people's requirements for the environment in cars are getting higher and higher. Modern cars, especially cars, are generally closed, especially in winter and summer. Therefore, the car is closed for a long time, and the air inside the car is often in a dirty state; Mixtures, etc. will lead to high formaldehyde content in the car, especially in the environment of new cars. The odor caused by smoking and carrying goods will increase as the car is used longer and more frequently. Bacteria and germs will accumulate over time. Breeding, spread to the air, thus affecting people's health. If the space inside the car is not sterilized in time, t...
