Abstract
A disinfectant include hydrogen peroxide and water, and is characterized by further including stabilizer, synergist and acid-value regulator, and it contains hydrogen peroxide 0.001-50 wt%, synergist in 0.0006-0.01 wt% of hydrogen peroxide, stabilizer in 0.001-0.03 wt% of hydrogen peroxide and acid value regulator to regulate the pH value of disinfectant to 2-4.5. The synergist is the oxide or salt of silver and the stabilizer is selected from poly phosphate, metaphosphate and pyrophosphate.
Description
The present invention relates to a kind of composite disinfection sanitizer of chemical composition and preparation method thereof that utilizes.
Hydrogen peroxide is as a kind of known chemosterilant, and its molecular composition is simple, and catabolite is water and oxygen, and human body and environment are not produced the residual toxicity effect, belongs to high effect disinfectants.But its poor stability, sterilization concentration height, cost is bigger when using in a large number, therefore, has restricted the application of hydrogen peroxide.
The purpose of this invention is to provide a kind of is the disinfection sanitizer and preparation method thereof of main component with the hydrogen peroxide, and disinfection sanitizer stability is high, and sterilizing power is strong, and effect is fast, and sterilization concentration is low.
Disinfection sanitizer of the present invention, comprise hydrogen peroxide, water, it is characterized in that also comprising stabilizing agent, synergist, acid number conditioning agent, by weight percentage, the concentration of hydrogen peroxide is 0.001～50%, the weight proportion of hydrogen peroxide and synergist is 1: 0.0006～0.01, and the weight proportion of hydrogen peroxide and stabilizing agent is 1: 0.001～0.03, and it is 2～4.5 that the acid number conditioning agent makes the pH value of disinfectant.
Described synergist can be the oxide or the silver salt of silver, and stabilizing agent is selected from polyphosphate, metaphosphate, pyrophosphate.
The acid number conditioning agent is inorganic phosphate or metaphosphoric acid preferably, preferred inorganic phosphate.
Above-mentioned synergist can be silver nitrate, silver sulfate, silver oxide, is preferably silver nitrate; Stabilizing agent can be a kind of in sodium phosphate trimer, PTPP, calgon, hexa metaphosphoric acid potassium, sodium pyrophosphate, the potassium pyrophosphate, is preferably calgon, hexa metaphosphoric acid potassium.
Preparation method of the present invention follows these steps to carry out:
(1) aqueous solution of preparation synergist obtains the silver components that silver ion exists;
(2) stabilizing agent is added in the above-mentioned silver components;
(3) mix with aqueous hydrogen peroxide solution;
(4) add acid number conditioning agent adjusting PH and Jia Shui and supply 100% of weight.
The solution that above-mentioned (2) obtain be preferably in stir and 0～25 ℃ down slowly importing contain in 35～60% the aqueous hydrogen peroxide solution.When adding the acid number conditioning agent preferably also in stirring and 0～25 ℃ of slowly adding.
The concentration of hydrogen peroxide of the present invention is suitable for the use under the various conditions, and proportioning the best of synergist, stabilizing agent should be that concentration of hydrogen peroxide is high more, and the amount of synergist, stabilizing agent is corresponding wants high.
Using method:
