Description
Technical Field
The invention relates to a mosquito-repellent fabric medicine mixture; in particular to a finishing liquid for treating mosquito repellent fabrics and a using method thereof.
Background
The mosquito repellent fabric treated by the insecticide is a relatively high-efficiency method in an insect-vector control method, and the methods widely recommended by WHO at present for spreading the diseases of the sand flies and the mosquitoes at night comprise long-acting mosquito repellent nets, insecticide treated materials and the like. The aims of preventing and treating disease transmission and protecting human health are achieved by preparing the fabric treated by the insecticide.
Currently, pyrethroids, one of the major compounds of long-acting mosquito repellent fabrics, are highly toxic when used alone, and with the increasing use of this organically synthesized insecticide, mosquitoes and flies develop varying degrees of resistance to this class of insecticide (gashiwu et al, china media biology and control journal, 2004,15(2), 105).
Chinese patent (publication No. CN 1099825) discloses a mosquito-proof, mosquito-killing and sterilizing fabric finishing liquid, a synergist is added in a formula, and after a liquid medicine consisting of a mosquito repellent, a mosquito killer, a bactericide, a synergist and the like is soaked and dried, the obtained fabric has mosquito-proof, mosquito-killing and sterilizing functions, but the formula serving as the mosquito-proof finishing liquid has the defect that the lasting pesticide effect time is only half a year and the lasting pesticide effect time is short. While only appropriate washing and sun exposure can be performed.
Chinese patent (publication No. CN1473988) discloses a method for producing mosquito net insect-proof fabric, the formula of fabric finishing liquid comprises pyrethrin, organic aromatic solvent, surfactant, cross-linking agent, catalyst, etc., the fabric is treated by the mosquito-proof treating liquid, and the treating process is carried out on padding equipment. However, the organic solvent used in the formulation poses certain threat to environmental safety.
Chinese patent publication No. CN 1664227A discloses a fabric finishing liquid for repelling and killing mosquitoes, which comprises insecticide, repellent, adhesive and cross-linking agent, and the fabric product finished by the fabric finishing liquid has strong capability of repelling and killing mosquitoes and is resistant to water washing, but the mosquitoes can generate resistance to the insecticide pyrethroid in the fabric finishing liquid along with the increase of the using time.
At present, the processing of the pyrethroid pesticides mainly uses organic solvents such as methanol, xylene and the like as solvents, and the use of a large amount of the organic solvents brings about a plurality of problems to the environmental safety. The pyrethrins act on mosquitoes in a contact mode and stomach toxicity mode, and the medicaments are ionic cone bottles which destroy neuron axes and disturb the access of sodium ions, so that nerve functional disorder, poisoning and death are caused. As the usage time increases, mosquitoes become resistant to pyrethroids. Mainly increases the activity of the multifunctional oxidase, reduces the penetration rate and is insensitive to nerves.
The resin composition disclosed in international patent publication No. WO2011/078375a1 can be prepared by loading a pyrethroid compound, one or more of a synergistic ether (PBO) and a phosphorus antioxidant on a carrier, and then melt-kneading the components with a thermoplastic resin. The pyrethroids and synergistic ethers used in this patent are prodrugs, which have the disadvantage that the release of the drug is not stable and is not easy to control.
Chinese patent publication No. CN102123593A discloses an insecticidal polymer matrix comprising HDPE (high density polyethylene), LDPE (low density polyethylene), preferably containing synergestic ether and deltamethrin. Deltamethrin is part of the material and is formulated to migrate from within the material to the surface of the substrate. But the release of the synergistic ether is unstable and the loss speed is higher in normal use.
Chinese patent publication (publication No. CN102149860B) describes that the improved textile contains at least two different yarn types, the first yarn type releasing at least one active ingredient selected from insecticides, and the second yarn type releasing at least one active ingredient selected from insecticides, insect repellents, pesticide synergists and chemosterilants, different from the first yarn. However, the method has complex manufacturing process and high manufacturing cost.
In connection with insecticidal control studies, insecticides are incorporated into polymeric materials to prevent insects from penetrating the material. However, controlling the release rate of the pesticide in the polymer matrix is also a problem today. Because the release of the insecticide is too fast to deplete the matrix quickly, the insecticidal effect is compromised because the insecticide is washed off, or the release is too slow to have the desired insecticidal effect, etc.
Aiming at the problems that the traditional mosquito repellent fabric finishing liquid causes environmental pollution due to the use of an organic solvent, and the single-dose pyrethrin pesticide has resistance, short lasting effect and poor washing resistance. And other patents adopt the thermoplastic resin which is melted and mixed, so that the problems of high manufacturing cost, inconvenient production and unstable release can be caused.
Disclosure of Invention
Aiming at the problems of drug resistance, environmental pollution and short duration of drug effect of the existing mosquito repellent treatment liquid, the invention provides the fabric finishing liquid for surface treatment of the fabric with long-acting mosquito repelling and killing effect according to the defects of the prior art. The textile finishing liquid does not contain organic solvent, does not threaten the environmental safety problem, and can realize clean production. The fabric finished by the fabric finishing liquid has long-acting mosquito repelling and killing effect and also has the same effect on resistant mosquito species. Meanwhile, the problems of short duration of the drug effect and poor washing resistance are solved.
The synergistic ether is added into the textile finishing liquid to be used as a synergist, and the effect of adding the synergistic ether is to inhibit the activity of the multifunctional oxidase, reduce the metabolism of mosquitoes on the pyrethroid insecticides and increase the toxic effect of the insecticides on the mosquitoes. Prolongs the duration of the drug effect.
The technical scheme of the invention is as follows:
a finishing liquid for treating mosquito repellent fabrics comprises the following components in percentage by mass:
the effective components are 1 to 30 percent of pyrethroid: 1% -20%;
the effective components are 10-30% of synergistic ether microcapsule suspending agent: 5% -30%;
adhesive with solid content of 10% -50%: 4% -50%;
a crosslinking agent: 0.15% -1.50%;
preservative: 1% -2%;
the balance of water.
In the finishing liquid, the effective content range of the pyrethroid is as follows: 0.2% -0.6%; synergistic ether content range: 1.5% -3%; binder solid content range: 2 to 5 percent.
The synergistic ether is prepared into a microcapsule suspending agent by encapsulating the synergistic ether; the preferred synergistic ether microcapsule suspending agent takes urea-formaldehyde resin as the capsule wall; the microcapsule suspending agent is prepared by encapsulating synergistic ether in core-shell structure particles prepared by an in-situ polymerization method.
The pyrethroid is one of cis-cypermethrin, cyfluthrin, cypermethrin, permethrin or deltamethrin insecticides.
The cross-linking agent is selected from one of epoxy resin or epoxy silane cross-linking agent; or two of the polyfunctional aziridine crosslinking agent and the trimethylolpropane substance in a mass ratio of 1: 1.
The preservative is dimethyl fumarate or cason.
The adhesive is one or two of water-based polyurethane emulsion, water-based polyacrylic acid emulsion or water-based vinyl acetate emulsion, and the mass ratio of the two is 1: 1.
The application method of the fabric finishing liquid is characterized by comprising the following steps:
1) firstly, finishing the fabric by padding equipment to uniformly spread the fabric;
2) putting the finishing liquid into a liquid tank; then, fully soaking the fabric in finishing liquor through a liquor tank;
3) the fabric fully soaked in the finishing liquor is rolled, and the pressure of the roller is adjusted to control the liquor carrying rate of the fabric to be 60-110%; then entering a drying and setting machine, wherein the drying and setting temperature is 60-120 ℃;
4) the fabric with mosquito repelling effect is obtained.
The invention can also adopt a two-step method to carry out the application method of the textile finishing liquor, and the finishing liquor in the step 2) is put into two liquid tanks; pyrethroid with 1-30 percent of effective ingredients and synergistic ether microcapsule suspending agent with 10-30 percent of effective ingredients are respectively put into the two liquid tanks; dividing other components in the formula into two parts according to the mass ratio of 1-5: 5-1, and putting the two parts into two liquid tanks; then, fully soaking the fabric in finishing liquor through a first liquor tank; after the step 3) is finished, putting the fabric with the mosquito repelling effect into a second liquid tank to be fully soaked with finishing liquid; then step 3) is carried out; the fabric with mosquito repelling effect is obtained.
The fabric prepared by the method contains the effective components of the pyrethroid insecticides of 50-270 mg per square meter of fabric and the effective components of the synergistic ether of 360-1350 mg per square meter of fabric.
The textile material is preferably polyethylene terephthalate.
The synergistic ether microcapsule suspending agent can be prepared by any method, and the prior synergistic ether microcapsule suspending agent can also be used; urea-formaldehyde resin wall material microcapsules are preferred;
the preparation of the urea-formaldehyde resin wall material microcapsule and the performance research thereof [ D ] in the university of eastern China, 2010 ] by using urea-formaldehyde resin as the capsule wall and adopting an in-situ polymerization method, can also be adopted by Van gegen. The preparation process comprises the following steps: 1) in a reactor, adding a certain amount of urea, resorcinol, ammonium chloride and a proper amount of an aqueous solution of an ethylene-maleic anhydride copolymer (EMA) with the mass fraction of 10% into the reactor to serve as a continuous phase of the reaction; after stirring and dissolving, adjusting the pH value of the continuous phase to 2.5-3.5 by using Na0H or Hcl solution, and starting mechanical stirring; 2) adding a synergistic ether raw pesticide accounting for 10-30% of the total mass of the microcapsule suspending agent, emulsifying for 30 minutes at the stirring speed of 1500rpm for 1000 plus materials, reducing the stirring speed to 750rpm for 300 plus materials, and adding 1-2 drops of n-octanol for defoaming; 3) then adding 10-30% formaldehyde solution with the mass fraction of 1.0-2.5 to the solution for reaction; raising the temperature of the solution to 40-60 ℃ at a temperature raising rate of 1-5 ℃/min, and preserving the temperature for 2-3h to finish the reaction; obtaining synergistic ether microcapsule water solution; 4) adding a proper amount of wetting dispersant, thickening agent and the like into the synergistic ether microcapsule aqueous solution, adding water and stirring uniformly to obtain the synergistic ether microcapsule suspending agent with the effective content of 10-30 percent.
The invention applies the microcapsule technology and solves the problems of high release rate of the synergistic ether and excessive loss in the washing process. The invention applies the method and the technology for preparing the capsule by the in-situ polymerization method introduced in the literature, and takes the synergistic ether as the capsule core and the urea-formaldehyde resin as the capsule wall. The particles with the core-shell structure prepared by the in-situ polymerization process encapsulate the synergistic ether to prepare the microcapsule suspending agent.
The prepared microcapsule has good physical and chemical stability and good storability. The urea-formaldehyde resin capsule wall on the outer layer can regulate and control the release rate of the synergistic ether, so that the synergistic ether has the effect of releasing for a longer time, and simultaneously, the direct stimulation to a human body is reduced. And the microcapsule structure can protect the capsule core synergistic ether, so that the amount of the synergistic ether dissolved in water in the washing process is reduced, and the loss in the washing process is reduced. The capsule structure can increase the pores of the capsule wall along with the increase of the ambient temperature, thereby increasing the release amount of the synergistic ether, and therefore, when the storage temperature is 30 ℃, the release of the synergistic ether can be accelerated, and the regeneration time of the synergistic ether is shortened. The fabric after being processed by the mosquito repellent finishing liquid prepared by using the structural substance can reduce the influence on release caused by washing, has short regeneration time and can achieve the long-acting mosquito repellent effect.
The term "regeneration time" means that the wash is capable of causing the loss of insecticide from the surface of the repellent fabric, but can be replenished by migration of the insecticide from within the fibre. The regeneration time is the time required to restore the effect of the pesticide.
The concrete description is as follows:
further: the mass content of the synergistic ether and the pyrethroid is the optimal proportion, and the synergistic ether can be seen from the attached figure 4: the mass ratio of the pyrethroids is 5-10: 1.
further: the existing materials of the fabric at present mainly comprise Polyethylene (PE) and polyethylene terephthalate (PET), the fabric material adopted by the invention is PET (trade name is polyester, and polyester is used for replacing the PET), and compared with other thermoplastic materials, the material has the following advantages: easy to purchase and low in cost. The strength is high, the heat resistance is good, and the composite material can be used at 70-170 ℃. Good wear resistance and can be used for a long time without damage.
Further: the sizing process for compounding the two effective components of the pyrethroid insecticide and the synergistic ether is a one-step method or a two-step method, and the fabric is subjected to post-treatment by the two methods. It can be seen from figure 2 that deltamethrin has a peak time of 6.401 minutes and an effective amount of 128 mg/m fabric, and figure 3 that synergistic ether has a peak time of 29.267 minutes and an effective amount of 386 mg/m fabric. The two substances exist in the fabric after the deltamethrin and the synergistic ether are compounded.
Further: the adhesive is a water-based adhesive with the solid content of 10% -50%, and the actual solid content range of the adhesive is as follows: 2% -5%; one of the following substances may be selected: aqueous polyurethane emulsion, aqueous polyacrylic acid emulsion, aqueous vinyl acetate emulsion and polybutadiene emulsion; or two adhesives with the mass ratio of 1:1 are selected, such as aqueous polyurethane emulsion and aqueous polyacrylic emulsion, and the aqueous polyurethane emulsion and the aqueous polyacrylic emulsion are compounded for use.
Further: the crosslinking agent is selected from one of the following substances, epoxy polymer crosslinking agent or hydroxymethyl crosslinking agent or carboxyl system crosslinking agent: epoxy resin, epoxy silane cross-linking agent, polyfunctional aziridine cross-linking agent and trimethylolpropane. Or selecting two of the cross-linking agents in a mass ratio of 1:1, such as a polyfunctional aziridine cross-linking agent and a trimethylolpropane cross-linking agent.
The finishing liquid provided by the invention combines pyrethroid and synergistic ether for use, and compared with the prior art, the finishing liquid can produce the following beneficial effects:
firstly, compared with a pyrethrin single agent, the mosquito repellent fabric finishing liquid has obvious synergy to mosquitoes, solves the problem of resistance, obviously improves the control effect, and the synergistic ether can inhibit multifunctional oxidase in the mosquitoes, which is the most important detoxification enzyme of the resistance.
Secondly, the addition of the synergistic ether reduces the dosage of the medicament and does not use any organic solvent in the fabric finishing liquid, thereby reducing the problem of environmental pollution.
Thirdly, the fabric finishing liquid has the advantages of long-acting washing fastness, and the formula of the fabric finishing liquid comprises: insecticides, synergists, binders, cross-linking agents, preservatives and water. The fabric finishing liquid composed of the mixed liquid is used for finishing the fabric. Because the cross-linking agent, the adhesive and the insecticide designed in the formula of the fabric finishing liquid have good associativity, the insecticide on the fabric can form good fixing force with fibers of the fabric after the fabric finishing liquid is padded, meanwhile, the application amount of the insecticide on the fabric can be accurately controlled and uniformly distributed through the liquid carrying rate, and the liquid carrying rate is adjusted through the pressure of the adjusting roller, so the mosquito-repellent fabric product obtained by the fabric finishing liquid and the finishing method has durable water washing resistance and strong mosquito-repellent effect. The experiment shows that after the fabric product is washed for 20 times by WHO standard (the washing program is a standard program recommended by the world health organization), the washable index of the pesticide can still reach 80-98%, and the biological test can also reach the standard requirement specified by WHO.
Fourthly, the mosquito repellent fabric can be obtained by directly carrying out dipping, rolling and drying treatment. The production process has simple flow, easy operation, industrial mass production and lower production cost than the melting and mixing method.
