Technical Field

The invention relates to the technical field of disinfectants, in particular to a solid chlorine disinfectant and a preparation method and application thereof.

Background

There is also a growing need for disinfectants to cope with the spread of some viruses. Chemical disinfectants on the market can be classified into solid, liquid, gas, gel and the like according to different forms. Wherein, the liquid disinfectant mainly comprises sodium hypochlorite, alcohols, hydrogen peroxide and the like, the gas disinfectant mainly comprises ozone, chlorine dioxide and the like, and the gel mainly comprises ethanol condensation and chlorine dioxide gel. The products are different in the capability of killing microorganisms, but compared with solid disinfectants, the products have the defects of large using amount, inconvenient transportation, low content of effective components and the like and are obvious when viruses are swept down.

The solid disinfectant in the current market mainly comprises chlorine-containing disinfectants mainly comprising calcium hypochlorite, trichloroisocyanuric acid and the like. Calcium hypochlorite has been gradually replaced due to its carcinogenic nature. Trichloroisocyanuric acid is only widely used in the fields of industrial water, swimming pool water and the like at present because of its extremely low solubility.

Chinese patent CN103891727A discloses a method for preparing a stable compound halogen organic disinfectant. The main effective components of the compound organic disinfectant are dibromohydantoin (or dichlorohydantoin or chlorobromohydantoin) and trichloroisocyanuric acid (or sodium dichloroisocyanurate); adding necessary adjuvants (anhydrous sodium sulfate, sodium chloride or sodium bromide, sodium carbonate or sodium bicarbonate, and sodium alkyl benzene sulfonate); dosage forms include powders, granules and tablets. The patent has low available chlorine content (20-38% or 45-55%), and poor disinfection effect.

Along with the attention of the national society on public health and health management, disinfectant products are developing towards the directions of high efficiency, low toxicity and environmental protection, and the development of a disinfectant which is green, environment-friendly, excellent in performance, convenient to transport and convenient to use is a necessary trend.
