Abstract

The present invention relates to one kind of environment friendly sprayed composite iodine disinfectant and its compounding process. The disinfectant consists of non-ionic surfactant Tween, iodine, potassium iodide solution and benzalkonium bromide and other synergist and stabilizer. Owing to the novel iodine carrier, the synergist and the stabilizer, the disinfectant has the features of fast iodine releasing and acting, less iodine color residue, raised permeability and no irritation to skin and mucous membrane. Therefore, the present invention may be used in effective disinfection of air and object surface and for clinical disinfection. The present invention may be disintegrated naturally and is environment friendly.

Description

technical field [0001] The invention relates to an environment-friendly spray-type compound iodine disinfectant and a preparation method thereof. Background technique [0002] The issue of public health has received widespread attention because of a sudden SARS outbreak at the turn of spring and summer in 2003. Since the coronavirus is transmitted through the air, the selection and use of efficient and environmentally friendly aerosol air disinfectants has become an important issue. Among them, oxidizing disinfectants, including peracetic acid, hydrogen peroxide, and simple substances and compounds of halogen elements, are widely used because of their good anti-virus effects. However, peracetic acid is very corrosive, and the acidification of the environment is serious after use. The release of oxygen after decomposition reduces the disinfection effect and causes the danger of explosion. After hydrogen peroxide is used, it will not produce substances that have a destructiv...
