Description
Technical field
The present invention relates to a kind of household chemicals compositions, specifically a kind ofly have health care, as family and the pure and fresh antibacterial gel-type paeonol air freshener of automobile indoor air.
Background technology
Common air freshener all is comprised of preparations such as essence and ethanol organic solvents basically, neither possesses health care, does not also have the effect of sterilizing, only plays the effect that abnormal smells from the patient improves.
A kind of good air freshener not only will possess the characteristics of killing various harmful microorganisms and eliminating noxious substance, but also should possess safety, efficient, wide spectrum, have no side effect, storage and the advantage such as easy to use.Consider the aspects such as sterilization effect, freshness effect, easy to use, toxic and side effects, Traditional Chinese drug air refreshing agent has research and development and is worth.Paeonol is a kind of spice, is again a kind of Chinese medicine, and is safe, and oral administration LD50 is 3430mg/Kg.Paeonol claims again paeonol, and chemical name is Paeonolum, and sterling is colourless acicular crystal.Adopt natural paeonol as the key component of air freshener, will when improving air odor, also have the function of sterilization, sterilization, health care.In addition, safe because this paeonol comes from pure natural plant, almost there is not untoward reaction, belong to real green, environmental protection, environmentally friendly air freshener.
Clinical multiplex in diseases such as cardiovascular and cerebrovascular vessel, tumor, inflammation, allergy and immune system [Chinese medicine information, 2009,26 (1): 20-22, Chinese invention patent 200510042537.5,200610096653.X] etc.; Also can be used as cosmetics [Chinese invention patent 200810157199.3], to spot dispelling whitening, delay skin aging, skin moistening moisturizing, anti-inflammation etc. all have preferably effect.Medicinal paeonol dosage form mainly contains injection, Emulsion, gel, ointment, liniment, pelliculae pro cavo oris, soft capsule [200410035585.7] and nano-emulsion [Chinese invention patent 200610104592.7] etc.Except being used for medicine, also be used as anti-mould and moth-proof agent.
Because paeonol is the crystalline particle of 51 ± 1 ℃ of fusing points, highly regular crystallization is so that its rate of release in environment is excessively slow, in order to make paeonol enough concentration be arranged to reach the effect of anti-mould and anti-moth in air, Yang Shunqi and Yao Risheng etc. [Chinese invention patent 200310112844] promote the volatilization of paeonol by adding Borneolum Syntheticum, and utilize free Borneolum Syntheticum or/and the speed releaser that natural camphor and beta-cyclodextrin inclusion compound Borneolum Syntheticum or natural camphor consist of and paeonol etc. have been mixed with control release type paeonol anti-mould and anti-moth solid tablet.But the adding of Borneolum Syntheticum is so that the abnormal smells from the patient of goods has stronger zest, is inappropriate to the air disinfection and refreshing of the environment such as family and automobile.So, prepare the air freshener take paeonol as Main Ingredients and Appearance, key is paeonol will be made certain preparation, comes the release of regulation and control paeonol.Especially solid preparation is convenient in production, accumulating and routine use meeting.
Summary of the invention
The object of the invention be to provide a kind of have health care, environmental protection, safe and reliable, as paeonol air freshener of family and the pure and fresh sterilizing of automobile indoor air and preparation method thereof.
The aquogel type air freshener that the present invention adopts the physics freeze-thaw method to prepare embedding paeonol and natural essential oil is made of following each component by mass parts:
All the other are water;
The degree of polymerization of described polyvinyl alcohol is 1700, and alcoholysis degree is 78%-99%.
Described polyvinyl alcohol replaces with the dextran of equivalent.
Described pregelatinized Starch replaces with polyacrylamide or the beta-schardinger dextrin-of equivalent.
Described alcohol solvent is with methanol or ether or the acetone solvent replacement of equivalent.
Described natural essential oil is selected from natural or synthetic Garden lavender, Flos Rosae Rugosae, tea tree ethereal oil.
Described physics freeze-thaw method is: at first utilize ethanol that paeonol and quintessence oil are dissolved fully, then an amount of polyvinyl alcohol (PVA) is dissolved in boiling in an amount of distilled water, paeonol after will dissolving under 60 ~ 70 ℃ of constant temperature at last and quintessence oil are injected in the PVA solution that high-speed stirred fast, mix 15 ~ 30s under the microwave assistant, fill after the cooling, freezing 2 ~ 3 hours of low temperature-20 ℃ ~ 0 ℃, freeze cycle 2～5 times.
Described physics freeze-thaw method has solved and has held allochroic shortcoming when chemical crosslink technique prepares air freshener.
Polyvinyl alcohol hydrogel of the present invention has the advantages such as high mechanical properties, hypotoxicity, good biocompatibility, and is nontoxic to human body.Polyvinyl alcohol can replace with dextran, has equally good swellability and water-retaining property.
The consumption of paeonol of the present invention can not be too large, generally is no more than 15%, prevents that paeonol is saturated not by gel embedding and crystallize out in hydrogel; Also can not be very little, otherwise do not have the effect of sterilizing.
Pregelatinized Starch of the present invention is used for improving molding time, shaping strength and the water retention property of polyvinyl alcohol hydrogel, and it can replace with polyacrylamide or beta-schardinger dextrin-, can achieve the above object equally.
Described solvent is selected from the low boiling point solvents such as methanol, ethanol, ether and acetone, preferably ethanol or acetone.
The visual fragrance size of the amount of described natural essential oil is regulated, and according to the needs of odor type, can adopt Garden lavender, Flos Rosae Rugosae, tea tree ethereal oil etc., and can add simultaneously some other essence, such as flavoring banana essence etc.
The hydrogel of the three-dimensional macromolecule network structure of utilization of the present invention comes embedding paeonol and natural essential oil, because the advantages such as its high mechanical properties, hypotoxicity, good biocompatibility, thereby reach the purpose that preparation has the paeonol air freshener solid preparation of sterilization, sterilization, health care, the used polyvinyl alcohol hydrogel of the present invention can make paeonol slowly volatilize, rate of volatilization is stable, and it is more lasting to use.
The present invention is not limited to as family and the pure and fresh sterilizing of automobile indoor air, can be used for equally weaving and the mildew-resistant of paper etc.
