Problems solved by technology

[0003] However, the biggest disadvantage of sodium dichloroisocyanurate is that it is easy to deliquesce, especially in an alkaline environment, the decomposed hypochlorous acid undergoes an acid-base neutralization reaction, which leads to a great reduction in the stability of available chlorine in chlorine-containing disinfection compound preparations
Especially after the implementation of the 2002 edition of the "Disinfection Technical Regulations", sodium dichloroisocyanurate was used as the main ingredient for disinfection and sterilization to prepare a compound disinfectant detergent containing surfactants. Because the drop rate of available chlorine exceeded 10%, it did not meet the requirements. The Ministry of Health requires that all products be withdrawn from the market

Abstract

The invention belongs to the technical field of disinfectant detergency and particularly relates to a chlorine-containing compound disinfectant detergent which takes sodium dichloroisocyanurate as a main material of disinfection and has relatively stable effective chlorine content and a preparation method of the chlorine-containing compound disinfectant detergent. The sodium dichloroisocyanurate compound disinfectant detergent is prepared from components in percentage by mass as follows: 5%-15% of sodium dichloroisocyanurate, 10%-15% of an anionic surfactant, 10%-25% of sodium carbonate, 10%-15% of sodium bicarbonate, 3%-10% of non-phosphorus water-soluble solid acid and the balance of filler, the moisture content of sulfonated matter is controlled to be not higher than 7%, the decrease rate of the effective chlorine content is lower than 10% and conforms to the requirement of 2002 version in Ministry of Public Health, and the disinfectant detergent is high in deterging ate and good in apparent density.

Description

technical field [0001] The invention belongs to the technical field of disinfection and washing, and in particular relates to a composite disinfection detergent which uses sodium dichloroisocyanurate as the main material for disinfection and sterilization and has a relatively stable effective chlorine content and a preparation method thereof. Background technique [0002] Sodium dichloroisocyanurate is a high-efficiency, low-toxicity, and broad-spectrum disinfectant recognized by various countries. By releasing hypochlorous acid, it denatures bacterial proteins, changes membrane permeability, interferes with the physiological and biochemical processes of enzyme systems, and affects DNA synthesis. cause rapid death of pathogenic bacteria. Sodium dichloroisocyanurate can not only strongly kill various pathogenic microorganisms such as bacterial spores, bacterial propagules, and fungi, but also has a special effect on hepatitis viruses. In addition, it can kill sulfuric acid re...
