(example 1)
In this example, the situation of modulating insect repellent coating about the extract that uses the whole strain grass of Pirolaceae Pylora rotundolia describes.At first, supply in extraction with after the whole strain grass of the Pirolaceae Pylora rotundolia plant thorough drying.The whole strain grass of Pirolaceae Pylora rotundolia plant is placed the mixed solvent (acetone: water=70 weight unit: 30 weight unit) flooded 48 hours of acetone and water.Use rotatory evaporator, concentrate the constituent concentration of the material in the mixed solvent that is soluble in acetone and water.The extract that obtains is the sticky material of chocolate high viscosity.
As extracting process, can use general method, the method with material plant position long-time dipping in mixed solvent is for example arranged, the temperature heating below the boiling point of mixed solvent, stir also extraction, filter and obtain the method etc. of extract.In this example, implement extraction, so obtain the extract of high insect repellent energy from the mixed solvent of acetone and water.
As shown below, this extract behind the dispersive, is blended in this dispersion liquid in the solvent that comprises coating resin in solvent, obtains insect repellent coating.This coating is coated in film surface, estimates avoiding that this films and keep away performance, below, expression evaluation experimental method, and expression is for the measurement result of keeping away performance of avoiding of the coating concentration of this extract.
The evaluation experimental method:
1. this extract 95 weight unit are dispersed in the preparation solvent.Then this dispersion liquid is blended in and comprises and be scaled in the solvent of coating resin that the drying solid composition is 5 weight unit the modulation insect repellent coating.
The solvent of Shi Yonging is the solvent that does not influence the character of coating resin herein.As solvent, the mixed solvent that a kind of solvent that suitable is in the colony that will select free water, methyl alcohol, ethanol, Virahol and acetone to form or plural number are planted the solvent combination.In this example, use about 40 ℃ warm water.
Coating resin can be the resin that generally uses in water-borne coatings.In this example, use the polyurethanes coating resin.With this polyurethanes coating resin emulsification, modulation is dispersed in polyurethanes coating resin (the following water soluble polyurethane resin that the also is called) coating in the water.For obtaining the easily viscosity of coating, the dilution of water soluble polyurethane resin coating is used with paint solvent (water).
2. at length of side 10cm (100cm
2), polyethylene terephthalate (PET) the film surface of thick 125 μ m, apply synthetic coating in above-mentioned 1.The method of coating can be used with known methods such as spray application, silk screen printings, and this example applies with rolling method.After the coating, in the free from dust part, fully ventilation is dried to till the thorough drying it.Below, the PET film of coating also is called " this extract ".Again, the water soluble polyurethane resin coating that does not contain this extract with above-mentioned 1 same method modulation.Apply the PET film that this coating obtains equally with above-mentioned, below also be called " blank group ".For the weight before and after the various sample determination coatings, calculate the net weight that is coated with application.
3. near four corners of the plastic cement experimental tank inner bottom surface of length of side 1m, with " this extract " and " blank group " separately 2 pieces place respectively with relative form.Near the central authorities of groove inner bottom surface, place the protection thing and the aqueous gauze in the residence that becomes cockroach.Near two pairs of samples (4 pieces) central authorities separately, place the sugar cube of having measured its initial stage weight.
4. in the gas temperature that controls environment is 27 ℃ above-mentioned experimental tank, puts into each 50 of male and female and amount to 100 Groton bug adults.Quite measure the weight of sugar cube after 72 hours, calculate the intake (sugar cube consumption) of sugar cube in the 4th day total of experiment beginning.
5. avoiding the rate of keeping away is calculated by following formula.
Avoid the rate of keeping away (%)=(1-(the mean square sugar consumption amount on " this extract ")/(the sugar cube average consumption on " blank group ")) * 100
Fig. 1 is that the net weight with this extract is illustrated in transverse axis, with the figure that the rate of keeping away is illustrated in the longitudinal axis that avoids of above-mentioned evaluation result.As shown in Figure 1, this extract demonstrates at the insect repellent energy that is present in the Groton bug in the living environment in a large number with the glue spread more than the 100mg/ sample piece.Again, the intensity of insect repellent energy is more than realistic scale.Because of insect avoid keep away find after the off-test dead individual, so can confirm the security of this extract.
In this example, water is described as the situation that is used for the solvent of dispersion extraction thing.But, the mixed solvent that can make at least a solvent in the colony that water, methyl alcohol, ethanol, Virahol and acetone forms or plural number plant the solvent combination aptly.For example, make the mixed solvent dispersion extraction thing of water 30 weight unit and ethanol 70 weight unit, also can confirm to disperse preferably and avoid and keep away performance.
And then, for the sample of above-mentioned optimal concentration, estimate to the insect repellent of the insect of other blattaria classes of Peroplaneta fluligginosa etc. can the time, identical with the situation of Groton bug, susceptible of proof has practical avoiding and keeps away performance.
(comparative example 1)
For comparing, keep away performance and relatively avoid by the cockroach of various extracts with the extraction process shown in the example 1 and as the general aqueous extraction method of extraction process.Its evaluation result is in following explanation.By the plant shown in the aqueous extraction method extraction example 1, obtain the water extract of the whole strain grass of Pirolaceae Pylora rotundolia plant.Estimate the insect repellent energy of this water extract.Evaluation method is used the evaluation method shown in the example 1.
Fig. 2 is that the net weight with this extract is illustrated in transverse axis, with the figure that the rate of keeping away is illustrated in the longitudinal axis that avoids of above-mentioned evaluation result.As shown in Figure 2, can confirm that water extract exists to avoid to keep away performance, but defective conclusion.For example, even if can confirm to use glue spread more than the 100mg/ sample piece of having confirmed effect in the example 1, also can not show being present in the insect repellent energy of the Groton bug in the living environment in a large number.
From Fig. 1 and result shown in Figure 2, can think that the stripping of effective constituent is few when extracting with respect to water, and during the mixed solvent of water and organic solvent, the stripping of effective constituent is more.Can illustrate that because the difference of extracting process it is also different to avoid the percentage extraction of keeping away effective constituent.
(example 2)
In this example, the situation of modulating insect repellent coating about the extract that uses the whole strain grass of Tropaeolaceae nasturtium plant describes.At first, supply in extraction with after the whole strain grass of the Tropaeolaceae nasturtium plant thorough drying.The whole strain grass of Tropaeolaceae nasturtium plant is placed the mixed solvent (acetone: water=70 weight unit: 30 weight unit) flooded 48 hours of acetone and water.Use spray-drying process, concentrate the constituent concentration of the material in the mixed solvent that is soluble in acetone and water.The extract that obtains is the sticky material of strong tea brown high viscosity.
As extracting process, can use general method, the method with material plant position long-time dipping in mixed solvent is for example arranged, the temperature heating below the boiling point of mixed solvent, stir, and extract, filter and obtain the method etc. of extract.In this example, implement extraction, so can obtain the extract of high insect repellent energy from the mixed solvent of acetone and water.
Carry out equally with the evaluation test method shown in the example 1, the modulation insect repellent coating is measured and is kept away performance with respect to the avoiding of coating concentration of this extract.Its result as shown in Figure 3.
Fig. 3 is that the net weight with this extract is illustrated in transverse axis, with the figure that the rate of keeping away is illustrated in the longitudinal axis that avoids of above-mentioned evaluation result.As shown in Figure 3, when this extract was a glue spread more than the 100mg/ sample piece, affirmation can demonstrate the insect repellent energy to a large amount of Groton bugs that exist in the living environment.Again, the intensity of insect repellent energy is more than the realistic scale.It is 0 that insect is avoided the dead number of individuals of keeping away after the off-test, so can confirm the security of this extract.
In this example, just the solvent as the dispersion extraction thing describes the situation of water.But, the mixed solvent that can use at least a solvent that will select in the colony that free water, methyl alcohol, ethanol, Virahol and acetone forms or plural number to plant the solvent combination aptly.For example, make the mixed solvent dispersion extraction thing of water 30 weight unit and ethanol 70 weight unit, also can confirm to disperse preferably and avoid and keep away performance.
And then, for the sample of above-mentioned optimal concentration, estimate to the insect repellent of the insect of other blattaria classes of Peroplaneta fluligginosa etc. can the time, the same with the situation of Groton bug, susceptible of proof has practical avoiding and keeps away performance.
(comparative example 2)
For comparing, keep away performance and relatively avoid by the cockroach of each extract with the extraction process shown in the example 2 and as the general aqueous extraction method of extraction process.Its evaluation result is in following explanation.By the plant shown in the aqueous extraction method extraction example 2, obtain the water extract of the whole strain grass of Tropaeolaceae nasturtium plant.Estimate the insect repellent energy of this water extract.Evaluation method is used the evaluation method shown in the example 2.
This result can confirm that water extract almost do not avoid keeping away property.For example, even be the glue spread of confirming in the example 2 more than the 100mg/ sample piece of effect, also can confirm to demonstrate insect repellent energy to a large amount of Groton bugs that exist in the living environment.
From this result, can think does not almost have the stripping of effective constituent when extracting with respect to water, and during the mixed solvent of water and organic solvent, the stripping of effective constituent can be carried out effectively.Difference because of extracting process is described thus, and it is also different to avoid the percentage extraction of keeping away effective constituent.
(example 3)
In this example, the situation of modulating insect repellent coating about the extract that uses Portugal section eucalyptus plant leaf describes.At first, supply in extraction with after the Portugal section eucalyptus plant leaf thorough drying.Portugal section eucalyptus plant leaf is placed the mixed solvent (acetone: water=70 weight unit: 30 weight unit) flooded 48 hours of acetone and water.Use spray-drying process, concentrate the constituent concentration of the material of the mixed solvent that dissolves in acetone and water.The extract that obtains is the sticky material of strong tea brown high viscosity.
Carry out equally with the evaluation test method shown in the example 1, modulate insect repellent coating, avoid with respect to the coating concentration determination of this extract and keep away performance.
Its result, this extract with the glue spread more than the 100mg/ sample piece, can demonstrate the insect repellent energy to a large amount of Groton bugs that exist in the living environment.Again, the intensity of insect repellent energy is more than realistic scale.It is 0 that insect is avoided the dead number of individuals of keeping away after the off-test, so can confirm the security of this extract.
In this example, water is described as the situation of the solvent of dispersion extraction thing.But, the mixed solvent that can use at least a solvent in the colony that choosing forms free water, methyl alcohol, ethanol, Virahol and acetone or plural number to plant the solvent combination aptly.For example, make the mixed solvent dispersion extraction thing of water 30 weight unit and ethanol 70 weight unit, also can confirm to disperse preferably and avoid and keep away performance.
And then, for the sample of above-mentioned optimal concentration, estimate to Peroplaneta fluligginosa etc. other the blattaria class insect insect repellent can the time, the same with the situation of Groton bug, susceptible of proof has practical avoiding and keeps away performance.
(example 4)
In this example, the situation of modulating insect repellent coating about the extract that uses the whole strain grass of Primulaceae Chinese sorghum grass plant describes.At first, supply in extraction with after the whole strain grass of the Primulaceae Chinese sorghum grass plant thorough drying.The whole strain grass of Primulaceae Chinese sorghum grass plant is placed ethanol and mixing of water molten profit (ethanol: water=70 weight unit: 30 weight unit) flooded 48 hours.Use spray-drying process, concentrate the constituent concentration that comprises of material in the mixed solvent that is soluble in ethanol and water.
Carry out equally with the evaluation test method shown in the example 1, the modulation insect repellent coating is measured and is kept away performance with respect to the avoiding of coating concentration of this extract.
Its result, this extract can demonstrate the insect repellent energy to a large amount of Groton bugs that exist in the living environment with the glue spread more than the 100mg/ sample piece.Again, the intensity of insect repellent energy is more than realistic scale.It is 0 that insect is avoided the dead number of individuals of keeping away after the off-test, so can confirm the security of this extract.
In this example, water is described as the situation of the solvent of dispersion extraction thing.But, the mixed solvent that can use at least a solvent that will select in the colony that free water, methyl alcohol, ethanol, Virahol and acetone forms or plural number to plant the solvent combination aptly.For example, make the mixed solvent dispersion extraction thing of water 30 weight unit and ethanol 70 weight unit, also can confirm to disperse preferably and avoid and keep away performance.
And then, for the sample of above-mentioned optimal concentration, estimate to other the insect of insect of blattaria class of Peroplaneta fluligginosa etc. avoid keep away give birth to can the time, the same with the situation of Groton bug, susceptible of proof has practical avoiding and keeps away performance.
(embodiment 5)
In this example, avoid about the insect that comprises the natural series antiseptic-germicide and to keep away coating and describe.The insect repellent coating of this example, comprising, different with the insect repellent coating of embodiment 1 as aspect the catechol of natural series antiseptic-germicide.Concrete is, the insect repellent coating of this example, 94 parts of extracts that comprise the whole strain grass of the Pirolaceae Pylora rotundolia plant that obtains equally with example 1, as 1 part of the catechol (Mitsui agricultural (strain) system) of tea extract, and be scaled the water-borne coatings of the water soluble polyurethane resin of 5 parts of drying solid compositions.Extract and catechol are dispersed in the water as paint solvent.The blending ratio of adjusting water is to obtain the best viscosity of coating state.Same with example 1, synthetic insect repellent coating is applied on the PET film, use insect (blattaria class), estimate the keeping away property of avoiding of this film.
Its result obtains the initial stage film performance and avoids to keep away performance and all film preferably.This is filmed be positioned over half a year in 37 ℃ the environment space that microorganism more easily breeds.Place the back and observe the result of film performance, compare, do not find microbial contamination with the insect repellent coating that does not add antimicrobial component, and so-called addling.That is, can prevent to avoid the microbial contamination that keeps away film.
As its reason, consider following situation.The insect repellent coating that comprises plant extract also comprises avoiding and keeps away effective constituent plant extract in addition.Avoid and keep away effective constituent and plant extract in addition thereof, think that the microorganism utilizability is all bigger, so the possibility that addles is arranged.Addling of this extract is not only and avoided the reduction that keeps away effective constituent, and covers film coated surface by the resultant that addles, and reduces the feeler of insect or the contact area of the forward foot in a step and film coated surface, keeps away the performance reduction so cause the contact of this extract to avoid.And then, become the thing that addles, when avoiding the situation of keeping away the performance disappearance, the anti-bait that becomes insect, and become the source of luring insect.
If according to this example, can prevent the deterioration that addles and cause by this extract and plant extract in addition thereof.Therefore, can guarantee to avoid and keep away continuing of performance.
The natural series antiseptic-germicide is not limited to above-mentioned catechol, and horseradish extract, the Meng, ancestor bamboo extract also can obtain same effect.Again, replace the natural series antiseptic-germicide, the compound agent that is contained in the effective constituent in the natural series antiseptic-germicide of use isothiocyanic acid allyl ester etc. also can obtain same effect.
Moreover, being the performance anti-fungal property, the anti-mycotic agent by using synthetic system can improve the anti-decomposability of insect repellent coating to fungi.
(example 6)
In this example, describe about the insect repellent coating that comprises silver-series antibacterial agent.The insect repellent coating of this example is considered to comprise the aspect of silver complex class antiseptic-germicide as silver-series antibacterial agent, and is different with the insect repellent coating of example 1.Set forth about concrete modulator approach.The absorption of thiosulfate anion silver complex loads on silica gel, will be with tetraethoxysilane hydrolyzate its surperficial silver complex class antiseptic-germicide (trade(brand)name: amenitop that is covered, Panasonic Electric Equipment Industrial Co.,Ltd's system) 1 weight unit, extract 1 weight unit of the whole strain grass of Pirolaceae Pylora rotundolia plant, be dispersed in as after in the water of 20 weight unit of solvent, stir and evaporating water.So, modulation insect that this extract is fixed on silver complex antiseptic-germicide surface is avoided and keeps away particle.For increasing its coating performance, water-borne coatings resin 2 weight unit are dispersed in the water solvent in advance.In this coating resin, disperse above-mentioned insect to avoid and keep away particle 98 weight unit, modulation insect repellent coating.
Method with same with example 5 is coated in this insect repellent coating on the PET film, estimates to avoid and keeps away performance and antimicrobial decomposability.Its result can confirm that practical avoiding keeps away performance and antimicrobial decomposability.
(example 7)
In this example, about using the extract of the whole strain grass of Pirolaceae Pylora rotundolia, the situation of modulation insect repellent spraying fluid describes.The modulation of extract is carried out equally with the method that discloses in the example 1.Concrete is at first with after the whole strain grass of the deer body grass section Pylora rotundolia plant thorough drying, to supply in extraction.The whole strain grass of deer body grass section Pylora rotundolia plant is placed the mixed solvent (acetone: water=70 weight unit: 30 weight unit) flooded 48 hours of acetone and water.Use rotatory evaporator, concentrate the concentration of the composition of material in the mixed solvent that dissolves in acetone and water.The extract that obtains is the sticky material of chocolate high viscosity.
After this extract disperseed in solvent, as required, additives such as dispersion auxiliary, alcohols such as interfacial agent are blended in this dispersion liquid, obtain the insect repellent spraying fluid.What alcohols was best is different with dissolving that can be used for this extract or dispersive alcohol (methyl alcohol, ethanol, Virahol) boiling point.For example, can list: multivalence alcohol such as ethylene glycol, propylene glycol, butyleneglycol, sugar alcohol.Because of multivalence alcohol has the interfacial activity effect, so, can carry out the adjustment or the optimization of droplet by using polyvalent alcohol as additive.That is, can use polyvalent alcohol as disperse additive.
This spraying fluid is sprayed on the film surface, estimates avoiding that this films and keep away performance.Evaluation method is used the method according to the evaluation method shown in the example 1.
The evaluation test method:
1. this insect repellent spraying fluid is modulated with aforesaid method.The solvent of Shi Yonging is the solvent that does not influence the spray operation of spraying fluid herein.As solvent, the mixed solvent that use that can be suitable will select at least a solvent in the colony that free water, methyl alcohol, ethanol, Virahol and acetone forms or plural number to plant the solvent combination.Use the mixed solvent of ethanol and water in this example.The addition of spraying fluid is this extract: ethanol: water: multivalence alcohol=10 weight unit: 60 weight unit: 10 weight unit: 10 weight unit.Moreover, use propylene glycol as multivalence alcohol.
2. length of side 10cm (100cm
2), the PET film surface of thick 125 μ m, apply synthetic spraying fluid in above-mentioned 1.After the coating,, fully take a breath and be dried to till the thorough drying locating of free from dust.Below, the PET film of coating also is called " this extract ".Again, the spraying fluid that does not contain this extract with 1 same method modulation.With the PET film of above-mentioned same this spraying fluid of coating, below also be called " blank group ".For the weight before and after the various sample determination coatings, calculate the net weight that is coated with application.
3. near four corners of the plastic cement experimental tank inner bottom surface of length of side 1m, with " this extract " and " blank group " separately 2 pieces place respectively with relative form.Near the central authorities of groove inner bottom surface, place the gauze that becomes the protection thing in cockroach residence and comprise water.Near two pairs of samples (4 pieces) central authorities separately, place the sugar cube of having measured its initial stage weight.
4. in the gas temperature that controls environment is 27 ℃ above-mentioned experimental tank, puts into each 50 of male and female and amount to 100 Groton bug adults.Quite measure the weight of sugar cube after 72 hours, calculate the intake (sugar cube consumption) of sugar cube in the 4th day total of experiment beginning.
5. avoiding the rate of keeping away is calculated by following formula.
Avoid the rate of keeping away (%)=(1-(the mean square sugar consumption amount on " this extract ")/(the sugar cube average consumption on " blank group ")) * 100
Avoid the result who keeps away benchmark test, same with example 1, demonstrate practical avoiding and keep away performance.Do not keep away dead individual after the off-test because of finding that insect is avoided, so can confirm the security of this extract.
In this example, just use the mixed solvent of ethanol and water to describe as the situation that is used for the solvent of dispersion extraction thing.But, the mixed solvent that can use at least a solvent that will select in the colony that free water, methyl alcohol, ethanol, Virahol and acetone forms or plural number to plant the solvent combination aptly.For example, make the mixed solvent dispersion extraction thing of water 30 weight unit and Virahol 70 weight unit, also can confirm to disperse preferably and avoid and keep away performance.
In this example, in order to modulate spraying fluid, add propylene glycol, but also can make other multivalence alcohol such as spent glycol, butyleneglycol, sugar alcohol as multivalence alcohol.Also can add other disperse additive, the condition that additive is realized spraying fluid again.
And then, for the sample of above-mentioned optimal concentration, estimate to the insect repellent of the insect of other blattaria classes of Peroplaneta fluligginosa etc. can the time, the same with the situation of Groton bug, susceptible of proof has practical avoiding and keeps away performance.
By above example, susceptible of proof comprises at least a kind the extract being selected from the colony that is made up of the extract of the extract of the extract of the whole strain grass of Pirolaceae (Pyrolaceae) pyrola plant, the whole strain grass of Tropaeolaceae (Tropaaeolaceae) nasturtium, Portugal section (Myrtaceae) eucalyptus branches and leaves and extract that Primulaceae (Primulaceae) thousand is bent the whole strain grass of platymisciums and the insect repellent coating of solvent, insect for comprising blattaria classes such as Groton bug or Peroplaneta fluligginosa at least has the insect repellent energy.
In the insect of using in the experiment,, do not find the sign of death thereafter etc. with the reason except old.This, it is different to think that insect is avoided being kept away by avoiding of ingesting of seeing in mechanism of keeping away and the former repellent more.Concrete is that the nerve conduction class that is contacted with medicament by the feeler or the forward foot in a step stimulates, and promptly avoids the person of keeping away by contact.Moreover, from duration of test,, be attended by the results of learning of insect for the action of insect of test, also can investigate the situation that obtains to be difficult to invade the area of application of this extract.
Among the present invention, in the extraction of the whole strain grass of Pirolaceae Pylora rotundolia plant, the whole strain grass of Tropaeolaceae nasturtium plant, Portugal section eucalyptus plant leaf and the whole strain grass of Primulaceae Chinese sorghum grass plant, with an organic solvent with the mixed solvent of water.Can think solvent-extracted before, by dried plant extraction position, the solvent that uses in the extraction is mixed solvent, can keep away that effective constituent extracts effectively in the relevant plant with avoiding with insect.
Pirolaceae Pylora rotundolia plant is put in order the extract of strain grass, the whole strain grass of Tropaeolaceae nasturtium plant, Portugal section eucalyptus plant leaf and the whole strain grass of Primulaceae Chinese sorghum grass plant, to the stronger insect repellent energy of cockroach performance of a large amount of existence in the living environment.These plants are considered the real result that uses as Chinese medicine, even can guarantee to be positioned over the security that also can not influence human health in the living environment.Again, these plants, as pharmaceuticals, change speech by with as utilizing only for the Chinese medicine diverse ways that uses in great and urgent occasion.That is, avoiding of obtaining from these plants keeps away composition, non-taking, and as often existing the chemical substance in the living environment to be used.
And then, nest by suppressing insect, can prevent that insect from pacing up and down.Therefore, performance can prevent the corrosion that the movement of insect causes, the microorganism diffusion of pacing up and down and generating because of insect, or take precautions against and be accompanied by allergy that dust or fungi the disperse effect in possible trouble, its industrial effect is bigger.
By the present invention, can provide effective, and few, i.e. the insect repellent coating of high security to the human influence to a large amount of sanitary insect pest or unhappy pest types that induce one that exist in the living environment.
