The environmentally-friendly sustained-release mildew-proof tablet comprises the following raw materials in percentage by weight: 2 to 10 percent of chlorine dioxide, 2 to 10 percent of essence, 40 to 85 percent of polyolefin particles and 2 to 10 percent of cyclodextrin. By the preparation method of the environmentally-friendly sustained-release mildew-proof tablet, a mildew-proof mixture is positioned between two degradable plastic layers or paper layers, laminated into one tablet and released slowly from the periphery of the mildew-proof tablet and the effective duration of the mildew-proof tablet is up to half a year so that the efficacy of the mildew-proof tablet is brought into play effectively.
Description
Technical field
The present invention relates to mildew resistant slice, relate in particular to a kind of environmental protection, sustained-release mildew-proof tablet and preparation method thereof.
Background technology
Mildew resistant slice is a kind of common elimination leather, the mouldy medicaments such as furniture, clothes, and its active ingredient is the volatile materials such as chlorine dioxide and volatile oil.In order to make its effectively effect of performance mildew-resistant, its active component must have good volatile performance.Yet common mildew resistant slice all is that active ingredient is embedded in plastics, filler and the binding agent in the market, and compressing tablet is made.Be 200810029893.7 such as application number, the utility model patent that name is called environment friendly mildew resistant slice and preparation method thereof has disclosed a kind of environment friendly mildew resistant slice and preparation method thereof, it comprises plastics, filler, wax and chlorine dioxide, and wherein, described plastics are selected from OPP, PUC or polyethylene.Extruding in flakes after high-temperature heating melted in extruder after above-mentioned material mixed.In the above-mentioned patent, described plastics, wax all are gas impermeable materials, and the chlorine dioxide embedding wherein is difficult to effective volatilization, thereby has affected drug effect.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of environmental protection, sustained-release mildew-proof tablet and preparation method thereof, this mildew resistant slice makes volatile medicine discharge from the periphery of mildew resistant slice, and drug effect can reach half a year to for a long time, thereby has effectively brought into play the effect of mildew resistant slice.
Technical scheme of the present invention is: a kind of environmental protection, sustained-release mildew-proof tablet comprise the raw material of following percentage by weight:
Solid chlorine dioxide 2～10%,
Essence and flavoring agent 5～10%,
Cyclodextrin 5～20%,
Filler 5～20%
Described polyolefin particles is selected from one or more mixture of polyethylene, polypropylene, ethylene-ethyl acrylate copolymer, vinyl-vinyl acetate copolymer.
Described essence and flavoring agent is selected from one or more the composition in the essential oil that mustard, Chinese cassia tree, red even root, horseradish plant extract.
Described filler is selected from one or more the mixture in any one or its mixture in calcium carbonate, talcum powder, silica flour, starch, silica, the alundum (Al2O3).
Also contain mass content and be 2～10% desiccant.
Described desiccant is selected from any or several mixtures in silica gel, alumina gel, the atlapulgite.
The preparation method of described environmental protection, sustained-release mildew-proof tablet comprises the steps:
Steps A: by the described solid chlorine dioxide of prescription weighing, essence and flavoring agent, polyolefin particles, cyclodextrin and filler, mix, make powder, be dissolved in glue, obtain the mildew-resistant mixture;
Step B: the mildew-resistant mixture of steps A gained is evenly sprayed or be coated on the face of the scraps of paper or film the scraps of paper or the film that obtain having medicine face and blank face;
