Detailed Description
The pesticidal composition and pesticidal method provided by the present invention will be further described below.
The invention provides a deinsectization composition which comprises a deinsectization liquid, wherein the deinsectization liquid comprises the following components in percentage by mass: 2-10% of pyrethrin, 5-8% of essence, 0-18% of emulsifier and the balance of solvent, wherein the vapor pressure of the pyrethrin at 25 ℃ is more than or equal to 0.6 mPa;
and the surface energy of the carrier is 30 dynes/cm-50 dynes/cm.
Specifically, the deinsectization liquid can be divided into aqueous agents or tinctures according to solvents.
When the deinsectization liquid is an aqueous solution, the deinsectization liquid consists of the following components in percentage by mass: 5 to 8 percent of pyrethrin, 5 to 8 percent of essence, 10 to 18 percent of emulsifier and the balance of water.
When the deinsectization liquid is a tincture, the deinsectization liquid consists of the following components in percentage by mass: 5 to 6 percent of pyrethrin, 5 to 8 percent of essence and the balance of ethanol.
The pyrethrin has a vapor pressure of 0.6mPa (0.6 x 10) or more at 25 deg.C-3Pa), high vapor pressure, easy volatilization at room temperature, and disinsection effect. Preferably at least one of transfluthrin with 25 deg.C vapor pressure of 0.91mPa, heptafluthrin with 25 deg.C vapor pressure of 80mPa, metofluthrin with 25 deg.C vapor pressure of 1.96mPa, and transfluthrin with 25 deg.C vapor pressure of 1.1 mPa.
The essence is used as an auxiliary component in the deinsectization liquid, is mainly used for improving the using effect of the deinsectization composition and gives out fresh fragrance in the using environment. It is understood that the specific components of the essence are not limited, and include floral essences such as roses, jasmine, cloves, lavender, sweet osmanthus, violet, chrysanthemum and the like; or non-floral essences such as lignum Santali albi, radix aucklandiae, and Moschus; or fruit-flavored essence such as apple, orange, grape, strawberry, lemon, etc.
Considering that the pyrethrin is easily dissolved in ethanol and not dissolved in water, when the pyrethrum liquid is a water agent, a proper amount of emulsifier, preferably polyoxyethylene ether, polyoxyethylene castor oil and the like, is added into the pyrethrum liquid, and the addition amount is preferably 10-18 percent of the total mass fraction of the pyrethrum liquid.
Specifically, the carrier having a surface energy of 30-50 dynes/cm may be made of various materials, for example, Polyethylene (PE) having a surface energy of 30-31 dynes/cm, polybutylene terephthalate (PBT) having a surface energy of 32dynes/cm, polyvinyl chloride (PVC) having a surface energy of 33-38 dynes/cm, Polyoxymethylene (POM) having a surface energy of 38dynes/cm, polyethylene terephthalate (PET) having a surface energy of 41-44 dynes/cm, and acrylonitrile-butadiene-styrene (ABS) having a surface energy of 35-42 dynes/cm.
Wherein the densities of PVC, POM and PET are all 1.38g/cm3About, higher than PE, PBT and ABS. When the carrier is made of PVC, POM or PET, the carrier has better effect of controlling the adsorption and volatilization of the pyrethrin and is more balanced and continuous. Therefore, the material of the carrier is preferably at least one of PVC, POM and PET, andone step is preferably PVC.
Further, the shape of the carrier is not limited, and includes a sheet shape, a mesh shape, a honeycomb shape, a sponge shape, a wave shape, and the like. In view of practical applicability, the carrier is preferably in the form of a sheet as shown in fig. 1, and in order to increase the surface area of the sheet-shaped carrier, the sheet-shaped carrier includes a
The sheet-like carrier may be folded and unfolded for use, in view of easier storage of the carrier when the pesticidal composition is not needed.
The deinsectization method provided by the invention comprises the following steps:
s1, providing a deinsectization liquid, wherein the deinsectization liquid comprises the following components in percentage by mass: 2-10% of pyrethrin, 5-8% of essence, 0-18% of emulsifier and the balance of solvent, wherein the vapor pressure of the pyrethrin at 25 ℃ is more than or equal to 0.6 mPa;
s2, providing a carrier, wherein the surface energy of the carrier is 30 dynes/cm-50 dynes/cm;
and S3, loading the deinsectization liquid on the carrier to volatilize the deinsectization liquid for spacial deinsectization.
In the method, the surface energy of the carrier is high, the surface atoms are unbalanced in stress, and when the pyrethrum liquid is loaded on the carrier, the carrier can reduce the unbalance of stress by adsorbing and agglomerating the pyrethrum liquid, so that the volatilization of the pyrethrin in liquid is controlled by the carrier, and the pyrethrum effect in the space is remarkable and continuous.
The loading method is not limited, and comprises the steps of spraying, coating and the like the deinsectization liquid on the carrier.
Considering the insect killing effect of the two components, every 400cm2The carrier of (1) is loaded with 0.1mL to 2mL of the insecticidal solution, preferably 0.13mL to 1.5 mL.
In daily use, 60m is used3And the area of the carrier is not less than 500cm in 24 hours2Preferably, the area of the carrier is 500cm2～800cm2Therefore, a smaller carrier is only needed for the space of a common bedroom to achieve a better deinsectization effect.
Therefore, the pyrethrin with the vapor pressure of more than or equal to 0.6mPa at 25 ℃ and the carrier with the surface energy of 30 dynes/cm-50 dynes/cm are selected to be matched for use, when the pyrethrin liquid is loaded on the carrier, the carrier can control the pyrethrin to naturally and continuously volatilize into the air at room temperature, and the effect of deinsectization is achieved. Therefore, the insecticidal composition of the invention does not need external energy such as fire, electricity and the like when in use, is convenient and safe to use, and has remarkable insecticidal effect.
