Description
Technical Field
The invention relates to a method for preparing composite quaternary ammonium salt disinfectant effervescent tablets, which belongs to the field of disinfectant effervescent tablets and comprises aldehyde, phenol, alcohol, halogen, quaternary ammonium salt, oxide and the like.
Background
Most of disinfectants used in the current market are inorganic chloride salts, such as bleaching powder, sodium hypochlorite and the like, formaldehyde, potassium permanganate and the like, and the disinfectants have the common defects of poor stability, short disinfection duration, slag after dissolution and poor oxidation performance, so that different requirements of various industries in the society cannot be met.
The dichloroisocyanuric acid and the trichloroisocyanuric acid are extremely strong oxidant and chlorinating agent, have high-efficiency, broad-spectrum and safe disinfection effects, have killing effects on bacteria, viruses, fungi, spores and the like, and are widely applied to disinfection in a plurality of fields such as environment, drinking water, animal feeding and the like. Since the powdery trichloroisocyanuric acid has the defects of inconvenient transportation, poor chlorine-constant effect and the like, the single-piece and compound-piece trichloroisocyanuric acid is widely used. However, in use, it was found that although the available chlorine content of the single-sided tablets was as high as 90%, the pH was low, the solubility was low, and the dissolution rate in water was slow, and in order to solve the above problems, those skilled in the art provided the compound tablets. The disclosed compound tablet is generally prepared from trichloroisocyanuric acid, sodium bicarbonate, organic acid and other raw materials, but the effervescent effect is not good enough, the decomposition of the product is serious in the storage process, the sterilization effect in the main technical indexes is quick, the environmental pollution is avoided, the failure is quick, bacteria are generated after 3 hours, the chlorine is gas, the stabilizing effect is poor, and the sterilization effect of the product is influenced.
The chlorine dioxide medicament is commonly used in a unitary mode and a binary mode, the unitary mode means that a precursor substance is passivated and then mixed with an activating substance, and the precursor substance is passivated, so that the solid state and the activating substance are mixed together and do not react, and chlorine dioxide cannot be generated before the precursor substance is dissolved in water. The binary precursor is not passivated and is separated from the activator (namely, the agent A and the agent B are commonly called) and dissolved in water together to react to generate chlorine dioxide. The monobasic chlorine dioxide is obtained by respectively carrying out barrier coating on sodium chlorite and an activating agent which are parent components of the chlorine dioxide through microcapsules or passivating agents, and the purpose of eliminating the reaction of the two is achieved after the two are isolated. The microcapsules or deactivators used must be water-soluble, and when placed in water, chlorine dioxide is immediately produced. Because the release agent must be water-soluble, the production, storage, transportation and use processes of some unitary chlorine dioxide products must be strictly dried and waterproof and separated all the time. Moisture can not occur in many links.
