Problems solved by technology

For boiled and wiped disinfectant, the disinfection effect is good in the case of repeated use every day, but for some objects that cannot be reached by manpower, such as the surface of objects that cannot be processed in time every day, it is often impossible to achieve all-round disinfection; for fumigation For disinfectant and spraying disinfectant, the disinfection effect is good in the case of airtight use, but what our workplace needs is air circulation, which will reduce its disinfection effect; and soaking disinfectant, usually only in the case of standardized use. Has a good disinfection effect
[0003] It can be seen that the liquid disinfection method often has problems such as inconvenient use, poor disinfection effect, and short duration.

Embodiment 1

[0018] A kind of retention slow release suspension disinfectant, its raw material comprises by weight percentage: sodium dichloroisocyanurate 2.5%, white carbon black 5%, titanium dioxide 5%, magnesium aluminum silicate 0.8%, polyvinyl alcohol 0.5%, defoaming Agent 0.3%, the balance is sodium dichloroisocyanurate suspension aqueous solution;

[0019] Wherein, in the sodium dichloroisocyanurate suspension aqueous solution, the content of sodium dichloroisocyanurate is 2.5%;

[0020] In the preparation process of sodium dichloroisocyanurate suspension aqueous solution, mix sodium dichloroisocyanurate, sodium dodecylsulfonate and water to obtain solution A; mix isophorone diisocyanate, azobisisobutyl Nitrile, emulsifier OP and acetone were mixed to obtain solution B; solution B was added to solution A, and sheared to form an emulsion; then polyethylene glycol was added dropwise to the emulsion at a rate of 1ml / min and continued to stir. After the addition was completed, the reac...

Abstract

The invention discloses a retention slow-release suspension disinfectant, the raw materials of which include by weight percentage: 2.5-10% of sodium dichloroisocyanurate, 5-10% of white carbon black, 5-10% of titanium dioxide, and 0.8% of magnesium aluminum silicate ‑1%, polyvinyl alcohol 0.5‑0.7%, defoamer 0.3‑0.4%, and the balance is sodium dichloroisocyanurate suspension solution. The invention also discloses a preparation method of the above-mentioned retention slow-release suspension disinfectant, comprising the following steps: uniformly mixing white carbon black, titanium dioxide, and magnesium aluminum silicate, performing wet ultrafine pulverization to obtain an intermediate material, and then mixing the intermediate material, two Sodium chloroisocyanurate, polyvinyl alcohol, defoamer and sodium dichloroisocyanurate suspension aqueous solution are mixed evenly, and sheared to obtain a retention slow-release disinfectant suspension. The invention has good bactericidal effect, long duration and convenient use.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a retention slow-release suspension disinfectant and a preparation method thereof. Background technique [0002] At present, the methods of disinfecting with liquid mainly include: boiling, wiping disinfectant, soaking disinfectant, fumigation disinfectant, spraying disinfectant, etc. For boiled and wiped disinfectant, the disinfection effect is good in the case of repeated use every day, but for some objects that cannot be reached by manpower, such as the surface of objects that cannot be processed in time every day, it is often impossible to achieve all-round disinfection; for fumigation For disinfectant and spraying disinfectant, the disinfection effect is good in the case of airtight use, but what our workplace needs is air circulation, which will reduce its disinfection effect; and soaking disinfectant, usually only in the case of standardized use. Has a good disinfec...
