Description
Technical field
The present invention relates to a kind of disinfectant, relate in particular to a kind of fresh-keeping air sterillization antibacterial of purification with fresh air, industry and domestic fungus-proof antisepsis, food and agricultural byproducts and preparation method thereof that is used for, belong to the gas depoisoning technical field.
Background technology
Chlorine dioxide is a kind of efficient, safety, the broad-spectrum antiseptic sterilization agent, be widely used in various water treatments, aspect such as air purifying and sterilizing and food antiseptic, particularly the chlorine dioxide product of slow release in a long time automatic slowly discharge the chlorine dioxide of low concentration constantly, kill airborne pathogenic bacteria and mycete effectively, remove airborne abnormal flavour, prevent that indoor article from going mouldy in malaria, air is sterilized, the double effect of sterilizing, simultaneously its atomic oxygen of decomposing out can also fresh air, can not bring harm and side effect to human body yet, can be applied to purification with fresh air widely, sterilizing, mildew-resistant, deodorization, the aspect such as fresh-keeping of food and agricultural byproducts.But at the slowly-releasing chlorine dioxide product that uses, have some shortcomings to some extent: (1) burst size is bigger, and effective life is shorter in the market; Burst size is not steady, and rate of release is difficult to control; (2) product uses agar as colloidal powder mostly, just begin slowly to discharge chlorine dioxide during sale, effect duration and shelf-life are short, and discharge inhomogeneous, some adopts silica gel as colloidal powder, makes numerous and diversely, just begins slowly to discharge chlorine dioxide when equally also having sale, effect duration and shelf-life are short, and discharge uneven problem; (3) also some product is with the technology of macromolecule water-absorbing body microgel agent such as polyacrylate, and they are often with two components of production sharing, puts together during use or directly makes gel, but also have the problems referred to above; (4) air after the sterilization lacks pleasant abnormal smells from the patient, is difficult for being accepted by people.
Summary of the invention
It is mild that technical problem to be solved by this invention provides a kind of gas release, effectively uses and long shelf-life, has sustained-release chlorine dioxide gel rubber powder of air sterillization and pure and fresh double effect and preparation method thereof.
The alleged problem of the present invention is solved by following technical scheme:
A kind of fragrant type sustained-release chlorine dioxide gel rubber powder, its special feature are that it is made up of the raw material of following unit of weight: chlorine dioxide matrix 8～24, slow release exciting agent 6～20, stabilizing agent 10～25, colloidal powder 10～24, cross-linking agent 3～7, solid essence 1～4; Described chlorine dioxide matrix is a kind of or its mixture in sodium chlorite, potassium chlorite, the barium chlorite; Described slow release exciting agent is a kind of or its mixture in boric acid, citric acid, tartaric acid, oxalic acid, the dihydric phosphate; Described stabilizing agent is a kind of or its mixture in anhydrous calcium chloride, anhydrous magnesium chloride, anhydrous sodium sulfate, the anhydrous magnesium sulfate; Described colloidal powder is a kind of or its mixture in polyacrylate, cross-linked poly(ethylene oxide), the alginate; Described cross-linking agent is a kind of or its mixture in acrylamide, the acrylates; Described solid essence is a kind of or its mixture in muscone, fragrant wingceltis Moschus, Flos Rosae Rugosae powder, the benzoin resin.
Above-mentioned fragrant type sustained-release chlorine dioxide gel rubber powder, described raw material consists of;
Chlorine dioxide matrix 10～20, slow release exciting agent 8～15, stabilizing agent 15～20, colloidal powder 12～18, cross-linking agent 4～6, solid essence 2～3.
Above-mentioned fragrant type sustained-release chlorine dioxide gel rubber powder, described raw material consists of: described sodium chlorite 12, boric acid 12, anhydrous sodium sulfate 20, polyacrylate 16, acrylamide 5, fragrant wingceltis Moschus 2.5.
A kind of preparation method of fragrant type sustained-release chlorine dioxide gel rubber powder, it may further comprise the steps:
A, with the 60 order chlorine dioxide matrix and the 120 order stabilizing agent mix homogeneously of formula ratio;
B, add 60 order colloidal powders, 60 order cross-linking agent, 60 order slow release exciting agents and the 60 order solid essence mix homogeneously of formula ratio in said mixture, above-mentioned moisture content of material is not more than 0.5%;
C, above-mentioned powder is distributed into bag, packing.
The present invention is a gel Ji with macromolecule water-absorbing bodys such as acrylates, and power goes into cross-linking agent, when product uses, chlorine dioxide under the cancellated constraint that cross-linking agent and gel Ji form, evenly release slowly, thus guarantee that effect duration is prolonged.And product is powdery when not using, and quite stable under stabilizer function can not discharge chlorine dioxide, and the shelf-life can reach 2 years.The adding of solid essence makes gel can discharge fragrance, in to air sterillization, and also pure and fresh air.It compared with prior art has following remarkable advantage: (1) preparation technology is simple, and is cheap, safe in utilization effective; (2) chlorine dioxide discharges gently, and effective life is longer, can reach 1-2 month; (3) can control the rate of release of chlorine dioxide according to the kind of slow release exciting agent; (3) product is stable, long shelf-life, and effect duration was above 2 years; (4) air after the sterilization has pleasant abnormal smells from the patient, can reach air sterillization and pure and fresh double effect.
The specific embodiment
Product usual condition of the present invention is monobasic powder, easily preservation, non-volatile down.It is made up of chlorine dioxide matrix, slow release exciting agent, stabilizing agent, gel, cross-linking agent, solid essence, directly adds during use in the entry, stirs and leaves standstill after 1 minute, can become fragrant type sustained-release chlorine dioxide gel rubber.Preparation principle of the present invention: chlorine dioxide matrix, slow release exciting agent and solid essence form colloid by gel in aqueous solution, in colloid inside, the slowed down association rate of chlorine dioxide matrix and slow release exciting agent of the crosslinked formed netted resistance structure of gel and cross-linking agent, reaction rate has greatly slowed down, the chlorine dioxide that reaction generates also is subjected to the influence of netted resistance structure, and diffusion rate has also slowed down in air.Therefore, the colloid internal structure has delayed the chlorine dioxide rate of release, thereby has prolonged the release time of sustained-release chlorine dioxide gel, reaches slow release effect.
Sustained-release chlorine dioxide gel activation and releasing mechanism are: in colloid inside, produce chlorine dioxide behind chlorine dioxide matrix and the slow release exciting agent priming reaction, increase along with the chlorine dioxide scale of construction, at the certain pressure of the inner formation of colloid, when internal pressure during greater than external pressure, the fragrance of chlorine dioxide molecule and solid essence is under the effect of pressure reduction motive force, and to external diffusion, this process can be considered the single physical diffusion of gas by the space.For colloid surface, the fragrance of chlorine dioxide molecule and solid essence directly spreads in air.For colloid inside, the fragrance of chlorine dioxide molecule and solid essence by colloidal space to diffusion into the surface.
Chlorine dioxide matrix and slow release exciting agent priming reaction formula are as follows:
5ClO
2 -+4H
+→4ClO
2↑+Cl
-+2H
2O
When the present invention uses, only bag need be opened and pour into (quality of water is about 5 times of powder quality) in certain water gaging, stir, chlorine dioxide matrix, slow falling in the exciting agent solid essence aqueous solution form colloid by gel, can become fragrant type sustained-release chlorine dioxide gel rubber and be placed into use occasion as requested.
