Abstract
A compound disinfecting tablet for medical tool, vegetable, fruit, etc. is prepared from percarbonylamine and sodium chlorite. Its advantages are high effect and stability, broad spectrum, quickly taking its dinfecting effect, low toxic, and low cost.
Description
The present invention relates to a kind of compound disinfecting tablet and preparation method thereof.Relate to a kind of kill all microorganisms efficient, fast, wide spectrum composite disinfecting sheet and preparation method thereof.This compound disinfecting tablet toxicity is low, and good stability is cheap, easy to use.
The chlorine dioxide of latest generation (the 4th generation) disinfectant of being generally acknowledged by people, be a kind of efficient, wide spectrum, disinfectant fast, but its use is very inconvenient, just stable under alkali condition during storing, must add acid activation again during use, and activation in a single day must be used as early as possible, otherwise just can lose efficacy, so it relatively is fit to now with the current.Though developed the technology of preparing of the stability chlorine dioxide aqueous solution and solid chlorine dioxide in recent years in succession, U.S. Pat P5399288, day disclosure is speciallyyed permit clear 60-161307, European patent EP 581550 and Chinese patent CN1094698, CN1196881A etc. have the elaboration of this respect, but up to now, still have some problems well not solve, for example: stability problem, toxicity and penetrating odor problem, precise metering problem during preparation or the like.Purpose of the present invention is exactly in order to address these problems.
Another kind of novel fine chemical product-percarbamide is with disinfectant H
2O
2, Peracetic acid relatively is that a kind of efficient, safety stores and transports, portably uses solid disinfecting agent easily.It is the addition product of hydrogen peroxide and carbonic acid amide, is to be the crystallization hydrogen peroxide of carrier with the carbonic acid amide, water-soluble back carbonic acid amide and H
2O
2Bacteriostasis, strong, the sterilization back non-residual toxicity of sterilizing power are all arranged, also non-stimulated, and also with low cost.
The present invention gets up this two kinds of antimicrobial activity things organic composition, make the compound disinfecting tablet, improved the stability of two kinds of antimicrobial activity things, simultaneously because the synergistic effect of two kinds of active matters, improved Disinfection Effect greatly, made that fungicidal spectrum is wider, toxicity is lower, price is more cheap, use is more convenient.
The present invention is achieved in that
At first active component percarbamide, sodium chlorite, citric acid and desiccant calcium chloride etc. are coated processing respectively, create the condition that can not directly contact between them; And then mix additive of tablet, direct compressing dry granulation; Adopt two aluminium packings at last.One. coat
1. percarbamide: adopt stearate and stearic compound as clad material, to crystalline state
Percarbamide coats.
2. sodium chlorite: adopt butadiene-styrene latex as clad material, the sodium chlorite aqueous solution is leaked with dropping liquid
Bucket drips in the benzole soln of the butadiene-styrene latex under continuous stirring slowly, makes liquid
Drip the suspension about diameter 100 μ m, this suspension carried out atomized drying,
Promptly get the coating of sodium chlorite.
3. citric acid: crystallization coats to citric acid as clad material to adopt polyacrylic resin.
4. calcium chloride: the employing ethyl cellulose is a clad material, and the aqueous solution of calcium chloride is splashed into ethyl
In the cellulosic toluene solution, form the suspension about 100 μ m, and this suspension is advanced
The row atomized drying promptly gets the coating of desiccant calcium chloride.Two. film-making
Prescription:
50 parts of 300 parts of pregelatinized starchs of percarbamide 100 ∽, 10 ∽
25 parts of 5 parts of superfine silica gel powders of sodium chlorite 1 ∽, 5 ∽
25 parts of an amount of zeolite 5 ∽ of citric acid
15 parts of 30 parts of stearic acid of calcium chloride 10 ∽, 5 ∽
Glycerine is an amount of
Method for making: the material of will writing out a prescription adds in the blender, fully mixes, and adopts the dry method direct tablet compressing,
Adopt two aluminium mmic packages at last.
Embodiment:
With percarbamide 100 grams, sodium chlorite 1 gram, calcium chloride 5 grams, pregelatinized starch 20 grams, stearic acid 5 grams, glycerine 10 grams fully mix, and 100 of direct tablet compressings, sheet weigh 1.4 grams.
Claims (4)
1. compound disinfecting tablet and preparation method thereof, it is by percarbamide and sodium chlorite isoreactivity component, prescription after coating, directly the dry method compacting is in flakes.It is characterized in that: percarbamide, sodium chlorite, citric acid isoreactivity component and desiccant calcium chloride etc. have been avoided haptoreaction to each other like this through coating the back prescription, have improved stability greatly.Its feature also is the prescription of tablet:
50 parts of 300 parts of pregelatinized starchs of percarbamide 100 ∽, 10 ∽
25 parts of 5 parts of superfine silica gel powders of sodium chlorite 1 ∽, 5 ∽
25 parts of an amount of zeolite 5 ∽ of citric acid
15 parts of 30 parts of stearic acid of calcium chloride 10 ∽, 5 ∽
Glycerine is an amount of
2. a kind of compound disinfecting tablet according to claim 1, its feature also is: described compound disinfecting tablet passes through the compound prescription of Tabules by percarbamide and sodium chlorite two active matters.
3. a kind of compound disinfecting tablet according to claim 1, its feature also is: the active component percarbamide and the sodium chlorite of described compound disinfecting tablet prescription, citric acid, desiccant calcium chloride etc. preferably coat through film, can improve the stability of product like this.
4. a kind of compound disinfecting tablet according to claim 1, its feature are that also best prescription is:
20 parts of 100 parts of pregelatinized starchs of percarbamide
5 parts of 5 parts of superfine silica gel powders of sodium chlorite
5 parts in 2 parts of zeolites of anhydrous citric acid
5 parts of 10 parts of stearic acid of anhydrous calcium chloride
10 parts of glycerine
