Description

FIELD OF THE INVENTION The present invention relates to an additive polymer composition for agricultural foil tents and similar structures comprising a light-transmitting polymer and an additive that absorbs the UV component of natural light. (The polymer may be polyethylene, polypropylene, PVC, polycarbonate, polystyrene, poly (methyl methacrylate) or a copolymer of said polymers.) The additive is capable of absorbing the UV component of natural light and emitting the absorbed energy in the orange-red spectrum. The additive is a f-element compound of the following general formula:

Me ⁿ 'XmYn - »' Lk (I) where

Me is Eu, Sm, Tb, Dy lantanida or UO2,

X and Y are chloride ions, nitrate ions; or an anion of monocarboxylic acids such as benzoylbenzoic acid, anthranilic acid; or anion of 3-diketones such as acetylacetone, benzoylacetone, dibenzoylmethane, benzoyl trifluoroacetone, tenoyl trifluoroacetone, hexafluoroacetylacetone,

L is a compound of Formula A, B, C wherein R is C 1-6 alkyl or phenyl; or

D, E, F is n or 3, m is 0 or 1k is 0, 1, 2 or 3.

In tents and similar structures, polymer kits that are specifically developed for these structures are required to accelerate the growth and growth of plants and increase crop yields. Such polymeric films shall meet the following requirements:

- adequate transparency in the visible spectral range,

- adequate absorption of the UV component of sunlight,

- good thermal insulation properties, ie adequate reflection of the infrared heat emitted by the soil,

- the preparation must not contain or select toxic substances under the conditions of use.

The 450,750 nm range of sunlight spectrum is important for the development and growth of plants. Within this range, the 580-750 nm range is particularly effective. 500-550 nm green light is less effective. From such light, the energy requirements of the plants are too great for proper development. UV radiation is harmful to plants, and IR radiation (750-1000 nm) is not absorbed or utilized.

Intensive research is underway in many countries to develop polymer formulations for agricultural tents and similar structures. The optical properties of the polymers are modified with chemical additives so that the growth and growth of plants grown under natural light in film tents or similar structures is particularly favorable.

Numerous polymeric formulations containing various additives for the formation of foil tents and similar structures, based on polyethylene, polypropylene, PVC, polystyrene, poly (methyl methacrylate) and copolymers thereof, are known. Additives form the specific properties of a given polymer which are required for the development and growth of plants. Such compositions are described, for example, in the Encyclopedia of Polymers, Volume 2. 950 (1974, Soviet Encyclopedia of Moscow).

It is also known that polymer formulations used to form film tents and similar structures are generally transmissive to ultraviolet sunlight, which adversely affects plants.

Several patents have suggested the use of additives that absorb UV radiation in polymers and thus remove UV radiation.

Japanese Patent No. 53-136,050 discloses a polymer film that absorbs UV radiation and is used in agriculture to make film tents. In the process of preparing the polymer composition, the film-forming polymer is blended with a plasticizer, a heat stabilizer (e.g., Τ1Ο2 and CaCCb), a pigment (e.g., carbon black) and dyes (e.g., phthalocyanine blue and green). The film-forming polymer can be PVC, polystyrene, polypropylene and poly (methyl methacrylate). The plasticizer may be a derivative of phthalic acid, maleic acid, citric acid or other acids. The film is extruded into a film having a thickness of 100 µm. The film absorbs UV radiation at wavelengths of 350-380 nm and has an absorption efficiency of 90%. Although such film effectively absorbs UV rays, it only transmits visible light to 40-50% and is unfavorable to the development of agricultural crops. A further disadvantage of such films is that they do not convert the absorbed UV light into red light and thus the sunlight cannot be effectively utilized by the plants.

U.S. Patent 4,081,300 discloses a polymer film that absorbs UV radiation in the wavelength range of 200-380 nm. The absorption efficiency is 90%. This film also efficiently absorbs UV radiation, but it also has a low transmittance in the spectrum of visible light spectra and cannot convert the absorbed UV light to orange-red light. As a result, the film is unable to maximize sunlight energy for the plants.

HU 198745 Β

French Patent No. 2,419,955 discloses polyolefin films for use in agriculture. The blend composition comprises at least 80% by weight of a polyolefin (e.g., a copolymer of polyethylene or ethylene-vinyl acetate), 1 to 15% by weight of Al (0H) 3 and

^I M2 M6 ^In (OH) 4 formula l2, alunite alkali metal sulfate, wherein M ¹ represents an univalent metal, M represents a trivalent metal ^onto (SO4) - mixture and ultraviolet radiation absorbing additive containing from 0.05 to 2 weight percent (e.g., benzophenone and benzotriazole). The finished polymer film has a low permeability in the 7-17 µm wavelength range and scatters light well, but cannot convert the absorbed UV light to orange-red light.

US 711 061 describes a polymer blend for the production of polymeric films for agricultural purposes. The composition of the mixture is 73-94 parts by weight of polyethylene or 15-20 tX of vinyl acetate copolymer containing 5-20 parts by weight of kaolin, 0.5-5.0 parts by weight of a wetting agent (e.g. amides) and 0.5-2.0 parts by weight of sorbitol and stearic acid. The film produced has a total permeability of 90% and a direct permeability of 45% in the visible spectral range of 380-780 nm. In spite of all its positive properties, this film cannot convert the absorbed UV light into orange-red light, ie it cannot ensure that the plants make full use of sunlight.

In U.S. Patent No. 4,220,736, a blend of 100 parts by weight of low density polyethylene or ethylene and 5-20 tX vinyl acetate copolymer and 1-20 parts by weight of polyacetal is proposed for the production of films. Films made from the blend have better light transmittance, strength and flexibility than films made from low density polyethylene. Applying the foils thus produced to plants for growing plants (greenhouses, driving sheds), the air temperature on the surface of the foil is 0.9-1.3 ° C higher than when using low density polyethylene foils. The disadvantage of such films is that they cannot effectively absorb UV radiation.

No. 53-12,169. Japanese Patent Application No. 5,451,125 describes polymeric films which are well absorbed by heat radiation. Modified polymers (polyethylene, polypropylene, etc.) are used to make the films. The modification is from 0.01 to 1 weight percent of the amount of the unsaturated carboxylic acids ¹ (e.g., acrylic, methacrylic, maleic, fumaric, itaconic acid and other acids), they are carried out and the anhydrides, esters, amides, or the modified and non-modified polymer mixture. The films thus produced absorb the heat radiation but not the UV radiation efficiently and are unable to convert the UV radiation to orange-red light.

No. 54-159,481. U.S. Patent Application No. 4,463,125 describes weatherproof films suitable for agricultural purposes. These transparent, heat-insulating, weatherproof, dust and cold water resistant, solid films have three layers.

The outer layer is 0.925 g / cm ³ high pressure polyethylene, the middle layer is a copolymer of ethylene and 14-28% by weight vinyl acetate and / or a copolymer of vinyl alcohol and 20-80 tX olefin (e.g. ethylene), the inner layer is high pressure polyethylene or ethylene-vinyl acetate copolymer or a mixture thereof. These films also do not absorb the UV component of sunlight efficiently and are unable to convert UV light to orange-red light.

No. 52-182,558. Japanese Patent Application No. 5,123,125 describes foils suitable for making agricultural foil tents. The films are manufactured from a blend of 100 parts polyolefin, 0.1-5 parts ion exchange resin and 1-5 parts surfactant. Preferably, the ion exchange resin contains sodium ion. The films produced in this way have good anti-adhesive properties and are maintained over the life of the films (up to 2 years).

The surfactant, which is constantly migrating to the surface of the film, provides the film with anti-adhesive properties for a long time and prevents water droplets from condensing on the inside of the film tent. Apart from their good antiadhesive properties, such films cannot convert the absorbed UV light into red light.

From the foregoing, it will be appreciated that the various additives added to the polymer or copolymer may influence the strength and heat absorption properties as well as the optical properties, in particular permeability in the UV range of the spectrum. Additives provide new materials that absorb 90% of the UV light.

The red component of sunlight is particularly important for plant development. Therefore, polymers used to cover agricultural film tents and similar structures require that the red spectrum component of the sunlight is transmitted to the maximum and that the absorbed UV component is emitted in the form of red light. Therefore, in order to ensure effective growth and development of plants planted in covered soils, such as foil tents or greenhouses, to accelerate the ripening process of their crops, substances that not only absorb the UV component of sunlight but also turn it into red light are needed. For use in agricultural foil tents and the like, a polymer composition such as that described in TU-35

HU 198745 Β has property, so far not described.

It is an object of the present invention to provide a polymer composition which is suitable for covering agricultural tents and similar structures, allowing plants to develop rapidly and increase their yield by making significant use of sunlight.

The doped polymeric composition for forming the agricultural film tents and similar structures of the present invention comprises a light-transmitting polymer and an additive that absorbs the UV component of natural light. The additive is capable of absorbing the UV component of natural light and emitting the absorbed energy in the orange-red spectrum. The general formula of the additive:

Me ⁿ * X.Yn -.- Lx (I) where

Me is Eu, Sm, Tb, Dy or UO2,

X and Y are chloride ions, nitrate ions; or an anion of monocarboxylic acids such as benzoylbenzoic acid, anion of anthranilic acid; or anion of β-diketones such as acetylacetone, benzoylacetone, dibenzoylmethane, benzoyl trifluoroacetone, tenoyl trifluoroacetone, hexafluoroacetylacetone anion,

L. is a compound of Formula A, B, C wherein R is C 1-6 alkyl or phenyl; obsession

D, E, F, n is 3 or 2, m is 0 or 1, k is 0, 1, 2 or 3.

The amount of the additive of formula (I) in the polymer may be from 0.001 to 5% by weight.

In particular, the following compounds may be used as additive: europium (III) trichloride tris (trioctylphosphine oxide), europium (III) trichloride tris (dihexylsulfoxide) eurium (III) trinitrate tris (tributyl). phosphate) eururaura (III) trinitrate (1,10-phenanthroline) uranyl di (hexafluoroacetylacetonate) - (triphenylphosphine oxide)

3zamarium (III) -tri (benzoyl trifluoroacetonate) - (2,2'-bipyridyl) terbium (III) -tri (acetylacetonate) bis (triphenylphosphine oxide) diprostium (III) tri (benzoyl) -trifluoroacetonate) -1,10-phenanthroline)

Various transparent polymers may be used, such as polyethylene, polypropylene, PVC, polystyrene, poly (methyl methacrylate), polycarbonate and copolymers thereof.

The preparation of the polymeric composition according to the invention is carried out as follows. The starting polymer is crushed and 0.001 to 5% by weight of an additive of formula (I) is added. The components are thoroughly mixed and the resulting material is extruded into a film.

Other formulations of the polymer composition are also possible. Then, 0.001 to 5% by weight of the additive of formula (I) is mixed with the liquid monomer and, after dissolution of the additive in the monomer, the reaction mixture is block-polymerized.

Based on the above, the amount of additive in the polymer or monomer is from 0.001 to 5% by weight. An additive content of less than 0.001% by weight causes a decrease in UV light absorption. An additive content greater than 5% by weight is also not desirable because the positive properties of the composition are no longer present. improved.

The polymer compositions of the present invention suitable for use in agricultural film tents and similar structures have the advantage that they exhibit improved optical properties compared to prior art polymer compositions used for similar purposes. The compositions of the present invention absorb at most 98% of the UV component of natural light at 200-450 nm and at max. 98% of the absorbed UV light. The 80X is turned into orange-red light. Thus, the total light transmission of the compositions increases from 50% to 81% in the orange-red spectral range of 580-750 nm.

The polymer compositions of the present invention used to cover film tents and similar structures allow for good development of crop crops planted in covered soil. Plants grow faster and produce more quickly. The ripening period and the mass yield period begin 3-14 days earlier. This is due to the fact that the use of the additives of formula (I) results in the polymer composition transforming the absorbed UV component of sunlight into orange-red light and thus ensuring that the plants make full use of sunlight.

Preferably, the polymer composition of the present invention is used for film tents and similar structures in which the following crops are grown: radish, lettuce, white cabbage, tomato, cucumber and paprika. Depending on the species and the variety, the yields of the cultures increase by 10-90% compared to the yields of cultures grown under the films without the compounds of the formula I.

Foil tents and similar structures covered with the composition of the present invention provide more favorable temperatures for the plants. The air temperature is 3-5 ° C higher than in parallel experimental foil tents for inspection. The compositions of the present invention provide good heat protection in the event of a mild frost. If the temperature in the open ground drops to -5 ° C, then in a control foil

HU 198745 Β the temperature is the same and the plants are completely destroyed. By using the composition of the invention, the temperature in the film tent is reduced to only 0 ° C under the same conditions and the plants are not damaged at all.

Depending on the nature of the polymer and additive, the type of additive and the amount of additive, a wide variety of polymeric compositions suitable for covering tents and similar structures can be produced.

Foil tents and similar constructions mean driving houses, greenhouses and greenhouses, where vegetables, greens, and other crops are grown under natural light in covered soil. The process for the preparation of the polymer compositions of the present invention is simple in technology and does not require any special equipment and conditions, so that it is possible to use conventional equipment for processing polymers under industrial conditions.

It has been found that vegetables grown in film tents covered with the material of the present invention not only develop faster but also give higher yields. For example, tomato yields are 50-90%, cucumber 15-50%, monthly radish 20-25%, salads 15-20%, peppers 15-20%, is 10-15% greater than vegetables grown in film tents covered with known polymer formulations. Based on the above mentioned advantages, it can be concluded that the composition of the invention can be used very economically.

Convert 70-85% to emitted orange-red light. Further, formulations containing the above additive are less susceptible to degradation by exposure to sunlight, and thus such polymer formulations have a longer lifespan than other formulations.
