Description

Manufacture of versatile insect repellent vinyl

The present invention relates to a method for producing a pest-avoiding vinyl and an anti-insect vinyl produced therefrom, a plant cultivation tray, a wrapping paper, a container, and an insect screen, which are mineral powders (stone powder) and vegetable powder materials, such as micronized pulp or cellulose fibers. It relates to a method for manufacturing a versatile pest-avoiding vinyl using various fibrous polymer materials, such as antibacterial vinyl, plant cultivation trays, wrapping paper, containers, and insect screens.

In recent years, as people's interest and preference for improving healthy living standards have improved, consumers' preferences and demands for eco-friendly agricultural products that do not use pesticides or drugs harmful to the body are increasing.

In particular, farmers or distributors who farm because they do not use pesticides of licensed items or remain unsanitized pesticides remain in the agricultural products due to restrictions of the PLS (Positive List System) system that will take effect from January 1, 2019. It has no choice but to be a burden in many ways.

Although it actually encourages the cultivation of eco-friendly agricultural products, it is very difficult to make farming without using pesticides in reality. Most farmers consider using pesticides as part of normal farming methods, and use less pesticides. It is because they prefer a lot of quantity using pesticides even if they sell low-priced agricultural products rather than produce agricultural products. In addition, it is true that by using pesticides, it is possible to effectively reduce the time of weeding or pesticide work in agriculture. Most of the pests that harm crops growing in rice fields are practically difficult to prevent, as people's personal activity is rare at night.

Considering this reality, farmers who want to safely produce various types of agricultural products and government authorities that supervise the production of safe food products need to renew their mindset on producing environmentally friendly agricultural products.

And, as explained above, agriculture can be said to be a war against weed control and pests. Until now, it was said that agriculture was devoted only to methodologies that could bring farmers' benefit through mass production without considering the toxicity of pesticides. From now on, it can be said that it is a time when efforts are required in various ways so that it can be safely delivered to consumers, from the production of safe agricultural products to the packaging and transportation of agricultural products.

Therefore, as part of these efforts, it is true that various insect repellents and repellents have been released one after another in order to safely grow agricultural products, and interest in using mulching vinyl has increased. As one of them, the content of agricultural mulching vinyl is proposed in JP 2007-209204A, but it is a chemical solution impregnated with only one surface, which is limited only to strength and physical properties of vinyl, and proposes a technical solution to provide actual control efficacy. There is a problem that it does not exist. In addition, in agriculture, pests are applied to the upper part, the upper part of the plant, while there are pests that inhibit the growth of the roots in the soil in the lower part or climb up and apply the upper part. It is a reality that there is a limit that can not be applied to raising seedlings, greenhouse houses, and road cultivation because they cannot be covered with this.

On the other hand, if you want to use a film or vinyl other than for agriculture, it is possible to prevent the invasion of some pests by manufacturing a vinyl that blocks ultraviolet rays in the range of 400 nm or less, but through this, it is not easy to prevent or avoid all of them as a whole, food When used for packaging of a company's packaging containers or precision equipment, the production of vinyl by eco-friendly drugs is required, but there is a problem that it is not easy to cover these needs.

And in this method of manufacturing vinyl, it is common to produce vinyl by an extrusion-type blow method. In this case, a process of coating vinyl on both sides of the front and back surfaces by cutting the vinyl and cutting it in half and re-adjusting it. There is a problem in that production efficiency decreases because a lot of labor and time are required.

In addition, the vinyl-based resin mixed with the drug is a thermoplastic resin, and the production amount is determined according to the rotational speed of the roller. If the impregnation speed of the drug is slow, the drying process may be convenient, but there is a problem that the production efficiency is poor. . However, if the impregnation amount of the drug is minimized, the drying process is also faster, so by impregnating only a minimum amount of the drug on both sides of the front and back surfaces of the vinyl, the drying speed is increased while passing through the heating air drying furnace in a short time, thereby improving the production amount. In practice, the retention time of the drug is important, but if the impregnation amount of the drug is minimized, problems may occur in the period during which the effect can be seen even by external conditions such as sunlight or temperature and humidity.

In addition, in the manufacturing method of the vinyl, the production of the vinyl raw material by the production of the existing master batch chip is molded at a high temperature of 200° C. or higher, that is, due to the difference between the melting point of the vinyl raw material and the temperature at which the pharmaceutical component volatilizes. However, since the possibility of deterioration in efficacy due to volatilization of pharmaceutical ingredients in the manufacturing process cannot be excluded at the source, technical means to supplement and solve these problems are needed.

Japanese Patent Publication JP 2007-209204A

Therefore, the object of the present invention is to solve the above-mentioned problems due to the difference between the melting point of the vinyl raw material and the volatilization temperature of the pest-avoiding material, and the technique for putting the pest-avoiding material in the vinyl, as well as vegetable essential oils or pest avoidance such as sterilization/insecticidal components. It is to provide a method for manufacturing a pest-avoiding vinyl by preparing a master batch containing a material, a porous stone powder/fibrous vegetable powder material, and a plastic resin such as EVA at a low temperature and mixing it with a vinyl raw material to produce a vinyl for pest control. .

After drying, it is kneaded with ethylene vinyl acetate resin to prepare a precursor prepreg at a low temperature of 130°C or lower, and it is easy to extrude and blow various types of sustained release vinyl and tray materials using precursor prepreg and vinyl raw materials by extrusion and blow method. It is to provide a method of manufacturing a vinyl for insect repellent that can be easily produced.

On the other hand, unlike the method of manufacturing a masterbatch comprising a plant essential oil, a vegetable powder material, an inorganic powder material, and an EVA resin and mixing it with a vinyl raw material, another object of the present invention is a plant essential oil, pesticide component, EVA It is to provide a method for producing a vinyl for insect repelling by a compound made of a resin, a vinyl raw material, linear low density polyethylene (LLDPE), a stabilizer, and a dispersant.

In the drying step, the temperature is 20 ~ 80 ℃, can be dried under low temperature and dehumidification conditions of 0% relative humidity. Here, in the case of a drying temperature, 30 to 80°C may be most preferable. As such, the drying step may be preferable because it can be dried at a low temperature and a very low relative humidity condition.

The plastic resin, polyethylene (PE, polyethtylene, LLDPE), ethylene-vinyl acetate (ethylene-vinyl acetate, EVA), ethylene methyl acrylate (EMA), PP (polypropylene), ABS (acrylonitrile-butadiene-styrene copolymer) Polymer), PS (polystyrene), SMMA (Styrene co-polymer maleian hydride), SBS (Styrene-butadiene-styrene block copolymer), MBS (methyl methacrylate-butadiene-styrene terpolymer), EVOH (ethylene vinyl alcohol) ), EPDM (ethylene propylene diene rubber), SEBS (styrene-ethylene-butadiene-styrene block copolymer), CPE (fluorinated polyethylene), and SAN (styrene-acrylonitrile co-polymer). have.

The plastic resin may include ethylene vinyl acetate having a vinyl acetate content of 10 to 20% and a melt index (MI) of 2.0 to 4.0 g/10 min. In this case, it may be desirable as the resin is smoothly mixed with the pest-avoiding material at low temperature and easily melted at low temperature. In this numerical range, it is possible to treat at low temperature, but if it deviates, it must be treated at high temperature. In this case, the pest repellent material may volatilize, so the content of the pest repellent material may be reduced.

In particular, when the content of vinyl acetate is 10% EVA, it is possible to provide the most desirable compounding condition, and when the melt index is larger from 3.0 to 4.0 g / 10 min, the larger the value, the better the melt at low temperature. Accordingly, it can be mixed well without volatilization of the pest-avoiding material, which is most preferable.

In the kneading step, based on a total of 100 parts by weight of the mixture of the dried material and the plastic resin in the drying step, the dried material and the plastic resin may be blended in a weight ratio of 1 to 30: 70 to 99, most preferably 10 to 30: It can be compounded in a weight ratio of 70 to 90, for example, in a weight ratio of 30:70. For example, when the dry matter containing the pest repellent material is blended in 30 parts by weight, the pest repellent material is evenly dispersed in the final product, the vinyl fabric, thereby providing an excellent pest repellent dissipation rate to maximize the pest repelling effect, which is most preferable. can do. On the other hand, if the dry matter containing the pest repellent material is blended in less than 1 part by weight, it is not evenly dispersed evenly in the final product, the vinyl fabric, and it is impossible to provide a pest repellent effect.

In the kneading step, kneading may be performed at a low temperature such as 60 to 130°C, preferably at a temperature of 100°C or less, and most preferably, prepreg is produced by kneading at a temperature of 60 to 130°C. can do. When the EVA resin and the VISTAMAXX resin are mixed and used in the temperature range of 60 to 130°C, it may be most preferable because they can be kneaded at a low temperature at the lowest raw material cost compared to other resins. On the other hand, if EVA resin and VISTAMAXX resin are used in combination at the above temperature, they have high price competitiveness with low raw material cost, but if they are outside the temperature range, there may be no price competitiveness in raw material cost.

In the step of manufacturing the vinyl, based on a total of 100 parts by weight of the mixture of the master batch and the vinyl raw material, the master batch and the vinyl raw material in a weight ratio of 1:99 to 40:60, 10:90 to 90:10 By weight ratio of It may be prepared by mixing, preferably by mixing in a weight ratio of 50:50, most preferably by mixing in a weight ratio of 30:70. Here, when mixing in a weight ratio of 30: 70, it has the advantage of evenly dispersing the master batch in the final product, the vinyl fabric, and provides the most economical mixing ratio to minimize the production cost because it can save the raw material cost as much as possible.

As an example, the wood powder may be a fine powder that has passed through 100 mesh or more, and the microfibrils are aggregate materials composed of a bundle of cellulose, which is a cell wall skeleton component of wood, and contain a trace amount of lignin, an adhesive component, to form an oily vinyl-based resin and adhesive. It has the characteristics of being able to bind alone without the same binder and is a fibrous material, so it can be preferable because it is an adhesive strength and can be mass produced at low cost. Here, when the material is specifically described, cellulose microfibrils (MFC) are aggregates of cellulose, which is a skeleton material of vegetable fibers such as wood. Plants including wood are typical composite materials composed of cellulose, whose main component is the skeleton, and a matrix that reinforces them, and LCC (Lignin-Carbohydrate Complex), which is a complex of lignin and hydrocarbon compounds. Cellulose accounts for about 50% of the world's plant-based products, and it can be said that the production of wood among plants is the largest. For pulping, vegetable fibers are treated chemically and mechanically, and cellulose microfibrils can be produced in this series of processes. It may be preferable because the prepreg, which is a mixture with a pest repellent material, can be prepared without adding a plastic resin because lignin, which is an adhesive component, remains in the microfibrils that are not lignin.

On the other hand, based on a total of 100 parts by weight of a mixture of pest repellent material (plant refinery), porous material and plastic resin, the pest repellent material, porous material and plastic resin are mixed in a weight ratio of 10 to 30: 10 to 30: 50 to 80 It may be desirable to be dried in step b).

In the step a), the specific impregnation method is adjusted to the target concentration by mixing with emulsified plant essential oil alone or other insecticidal components, and finely pulverized pulp and porous materials such as microfibril cellulose and diatomaceous earth for 3 minutes to 10 minutes. After mixing in minutes, using a dehumidifying dryer at 80℃ or less, the masterbatch is produced at a rotor speed of 1500rpm or less. Pest-avoiding vinyl production is produced by mixing at the same time as the vinyl raw material, or first melt the vinyl raw material LLDPE for 2 minutes, then add the master batch and mix it with the master batch in a Brabender plasticorder below 130°C for 5 minutes or less, and then 60~100rpm. At a rate, vinyl is produced by the extrusion blow method.

In the step b), the condition of the drying process is a method in which a low temperature dehumidification and drying method adopts a low temperature in terms of energy efficiency or technical problems. to provide.

In step c), a thermoplastic resin may be used as the plastic resin, for example, polyethylene (PE, polyethtylene, LLDPE), ethylene-vinyl acetate (EVA), ethylene methyl acrylate (EMA), PP (Polypropylene), ABS (acrylonitrile-butadiene-styrene copolymer), PS (polystyrene), SMMA (styrene copolymer poly maleane hydride), SBS (styrene-butadiene-styrene block copolymer), MBS (methyl meta Acrylate-butadiene-styrene terpolymer, EVOH (ethylene vinyl alcohol), EPDM (ethylene propylene diene rubber), SEBS (styrene-ethylene-butadiene-styrene block copolymer), CPE (fluorinated polyethylene), and SAN (styrene- Acrylonitrile co-polymer).

As an example of these, in step c), it may be desirable to knead a ratio of LLDPE resin, EVA resin, VISTAMAXX or EMA resin (+ 3% of maleic acid compatibilizer) in a weight ratio of 60:40 to 70:30. .

In addition, as another example of these, in the step c), when prepreg is prepared by kneading using EVA resin, the content of vinyl acetate is low in the range of 10-20% and the Melt Index (MI) is 3.0-4.0. It may be desirable to use vinyl acetate content as high as g/10 min. In this way, by controlling the content of vinyl acetate, density, flexibility, and manufacturing temperature can be controlled, so that the drug efficacy of the pest-avoiding substance can be as long as possible, and the insect avoidance function such as agriculture, fruit or food packaging, and insect screening can be continued. It may be desirable to be able to produce an optimum pest repellent vinyl, film and tray with excellent sustained release for various uses.

In the prepreg of step c), it may be desirable to include a pest repellent material and an EVA resin comprising a vegetable essential oil component, an insecticide and a fungicide in a weight ratio of 30:70.

In the step c), it may be kneaded at a low temperature, such as 60 ~ 130 ℃, preferably may be a temperature below 100 ℃, most preferably 60 ~ 130 ℃ It may be most desirable to prepare the prepreg by kneading at the following temperature.

At the time of kneading, in step c), based on a total of 100 parts by weight of the mixture of the dry matter of step b) and the plastic resin, the dry matter and plastic resin may be blended in a weight ratio of 1 to 30: 70 to 99, most Preferably in a weight ratio of 10 to 30:70 to 90, for example, in a weight ratio of 30:70, it can be blended.

As described above, according to the present invention, as the pest repellent material at low temperature, the porous/fibrous vegetable powder material, and the plastic resin such as EVA can be mixed and kneaded at low temperature, the pest repellent material is easily evaporated at high temperature. Since volatilization of the substance is suppressed, it is possible to provide a vinyl having a long-term pest-avoiding effect capable of releasing a pest-avoiding substance for a long time.

In step c), the prepared prepreg is made of, for example, a vegetable material made of fine powder of 100 or more mesh containing plant essential oil or a sterilizing/insecticide component, and vegetable fiber such as vegetable microfibril cellulose (MFC) and wood or rice husk. A composite material made of a porous material such as activated carbon and EVA resin, which is a precursor before making vinyl.

As such, when the pest-avoiding material is put into the vinyl, the melting point of the vinyl raw material and the volatilization temperature of the pest-avoiding material are different, so that the pest-avoiding material is easily volatilized at a high temperature. When using vegetable microfibrils as one component of this substance, as described above, this substance is a collection of cellulose, which is a polysaccharide of β1,4-glucoside, which is a skeletal substance of a plant, and is a nanometer unit as a fibrous polymer substance and is composed of hemicellulose and lignin. Because it is an integrated composite fiber, it has strong strength and can be used as a nano-cellulose composite material, lignin is a polymer amorphous material, and it can have the advantage of being able to make prepregs and pest-avoiding materials injected without EVA resin as an adhesive component. . In addition, in the present invention, when the content of vinyl acetate is low in the range of 10 to 20% and the Melt Index is 3.0 to 4.0 g/10 min, when using EVA resin using high vinyl acetate, prepreg can be prepared at a low temperature of 100°C or less. There is an advantage.

In the step d), as the vinyl raw material, for example, polyethylene (including PE, polyethtylene, HDPE, LDPE, LLDPE), polypropylene (PP, polypropylene), polycarbonate (PC, polycarbonate), acrylonitrile-butadiene-styrene Resin (ABS, acrylonitrile butadiene), polybutylene terephtalate (PBT), polyethylene terephtalate (PET), polyphenylene sufide (PPS), poly styrene (PS), Polyvinyl chloride (PVC), polyetherimide (PEI), acetal, and urethane can be used, and these resins are blends or blends of single or two or more materials as raw or recycled resins. Can be used.

Here, in addition to polyethylene (PolyEthylene), polypropylene (PolyProphlene) in consideration of environmentally friendly aspects and product characteristics, polyethylene telephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS) or polycarbonate (PC) It may be used to further include a resin selected from the group consisting of, but is not limited to this.

In the step d), when the prepreg and the vinyl raw material are blended in a certain ratio, the mixing ratio thereof can be adjusted according to the concentration of the pest repellent material impregnated in the prepreg, and the prepreg and the vinyl raw material are 1: It can be prepared by mixing in a weight ratio of 99 to 50:50, preferably by mixing in a weight ratio of 10:90 to 40:60, most preferably in a weight ratio of 30:70. have.

This has a possibility that uniform dispersibility may be a problem because a small amount is mixed instead of reducing the weight ratio of the vinyl raw material and the master batch when the concentration of the pesticidal component such as essential oil impregnated in the master batch is reduced. On the other hand, if the amount of the masterbatch impregnated with low concentration is mixed with a large amount of vinyl raw material, it is characterized in that uniform dispersibility can be achieved. Therefore, the mixing ratio at the time of manufacturing the masterbatch can affect the final pest-avoiding vinyl product blending ratio with the vinyl raw material.

As an example, when the blending weight ratio of Prepreg and LLDPE, which is the masterbatch, is 30:70, it may be most preferable because the economical efficiency of plant essential oils and pesticides and the dispersibility of the final vinyl product are the best. Here, the impregnation of the pharmaceutical component, which is the most problematic in the preparation of the prepreg, is low temperature of 120°C or less, so the viscosity of vinyl acetate that melts well at low temperature during prepreg production, that is, Melt Index is 3.0~4.0 g/10 min, high acetic acid. It may be preferable to use EVA resin using vinyl.

In the step d), a vinyl raw material such as prepreg and polyethylene is blended in a certain ratio, and a vinyl having a thickness of 0.020 to 0.040 mm can be produced by an extrusion blow method,

In the step d), the prepreg and the vinyl raw material may be mixed at the same time to produce an extrusion blow method, or the vinyl raw material may be melted and then added to the prepreg and mixed to prepare the extrusion blow method. After the LLDPE is melted for 2 minutes, the masterbatch is added, and after mixing with the masterbatch in a Brabender plasticorder of 180°C or less for 5 minutes or less, vinyl may be produced by an extrusion blow method at a rate of 60 to 100 rpm.

In the step d), it is preferable that the thickness is 0.020 to 0.040 mm, for example, 0.03 mm may be preferable in the case of mulching vinyl, and in the case of crops with a long service life, thicker 0.04 mm is used. It may be desirable. On the other hand, when using for crop growth of about 3 months, it may be preferable to use a thinner 0.02mm. Since these are directly related to the production cost of vinyl sold in kg, it is possible to produce vinyls of various thicknesses by dividing them by crop type. In addition, in the case of a tray, which is a plant bed, the thickness is thicker than this, and may be produced in various thicknesses because it is produced by a press process. When the thickness is thick, since the content of the insect repellent material is relatively high, the insect repellent effect may be improved.

As described above, various forms of vinyl, film, and tray may be manufactured through the step d). In addition, it is possible to easily manufacture vinyls and films and trays for various purposes, such as insect screens and food packaging, in addition to agricultural use. As described above, according to the present invention, sustained-release vinyls and tray materials for various uses are easily extruded and blown by a method. It can be manufactured.

As described above, according to the present invention, the plant essential oil or hydrating agent and the sterilizing/insecticidal component of the emulsion are wood flour or chaff, vegetable fine powder such as vegetable microfibril cellulose or vegetable carbide such as activated carbon and porosity such as zeolite, ocher, stone powder, diatomaceous earth, etc. After being impregnated with the material and dried, it can be kneaded with ethylene vinyl acetate resin to produce a precursor prepreg at a low temperature of 130° C. or less, and as such, it is possible to manufacture at a low temperature. Since volatilization of the repellent substance is suppressed, it is possible to provide a vinyl having a long-term pest repellent effect capable of releasing the pest repellent substance for a long time.

Changes over time were observed with the naked eye (FIG. 5), and lethality was assessed after 24 hours. As a result, unlike the control film according to Comparative Example 13.3% mortality as shown in Figure 6, the vinyl according to Example 2 of the present invention has a high mortality rate of 43.3% excellent insect repellent and control effect is avoided Confirmed.

Second, the vinyl was cut to a diameter of 15 cm, placed in a glass cylinder having a height of 15 cm × 1.5 cm in diameter, and 30 tobacco powder (Bemisia tabaci) were added and sealed with parafilm. Changes over time were observed with the naked eye (FIG. 7 ), and lethality was assessed after 24 hours. As a result, unlike the 6.7% mortality of the control film according to the comparative example, as shown in FIG. 8, the vinyl according to Example 2 of the present invention has an excellent insect repellent and control effect with a high mortality rate of 26.7% Was confirmed.

Third, 30 cigarettes (Bemisia tabaci) were put into a petri dish having a height of 4 cm and a diameter of 9.5 cm, and the upper portion of the petri dish was covered with vinyl cut to a diameter of 15 cm. Changes over time were observed with the naked eye (FIG. 9), and lethality was assessed after 24 hours.

Was confirmed.

Thus, in the case of the vinyl according to the embodiment of the present invention, unlike the vinyl according to the comparative example, it is possible to provide a very good mortality rate of the pest, and in three installation methods, the vinyl according to the embodiment of the present invention is a field for cultivating crops. When applied to, it was confirmed that installation on the floor provides the best pest mortality.

<Experiment 3> Cultivation test of crops using pest-avoided vinyl
