Description

568935 A7 B7 V. Description of the Invention (i) Technical Field The present invention relates to agricultural covering materials, and in particular, it relates to tunnel greenhouses, tubular greenhouses, large-scale greenhouses, and other agricultural or horticultural facilities for deployment or for indoor use. The fluorocarbon resin film has excellent flexibility, durability, dust resistance, light transmission, etc., and is used for agricultural coating materials. BACKGROUND ART Conventionally, films of polyethylene, ethylene-vinyl acetate copolymer, polyester resin and soft vinyl chloride resin are used as agricultural covering materials for tunnel greenhouses and tubular greenhouses. Soft polyvinyl chloride resin films are used in In terms of construction price and thermal insulation, it is superior to other materials' films, and occupies most of the agricultural covering materials. However, since the soft polyvinyl chloride resin film contains a plasticizer, the surface of the film is easily contaminated by the bleeding of the plasticizer, and there is a problem that the light transmittance decreases in a short period of time. In addition, each of the above-mentioned films is combined with an ultraviolet absorber to improve weather resistance. However, it is usually necessary to stretch for 1 to 2 years due to deterioration caused by sunlight, temperature, wind and rain, and oxidation. Moreover, such films that have been mixed with UV absorbers are different in their UV absorbability. Because they can block UV rays, they are used to cultivate crops that require UV rays (eg eggplants, certain types of flowers), or bees that require UV rays for activities Or pollen crops (such as strawberries, cantaloupe, watermelon, green pepper, etc.) are not suitable for cultivation. On the other hand, real large-scale greenhouses have also been adopted for the purpose of saving labor in greenhouse management, expanding cultivation area, and prolonging the lifespan of greenhouses. In this large-scale greenhouse, polyester resin and polycarbonate resin have been used as hard paper. The standard of Chinese paper (CNS) A4 (210 X 297 mm) is applicable (please read the precautions on the back before filling this page) ---- Order.L --- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4-568935 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) Polyvinyl chloride resin, acrylic ester Covering materials such as resins, fiber-reinforced plastic edges, and glass plates are used for long-term stretching for more than 5 years. However, these covering materials are thicker and thicker, so they must be stretched on a greenhouse with large special substrates as bone groups. Its stretch-and-stretch construction is also very complicated and has the disadvantage of being expensive. In addition, polyester resins, polycarbonate resins, rigid polyvinyl chloride resins, acrylate resins, and the like are liable to crack due to hail and the like, and the cracks that have occurred have the disadvantage of being easy to spread. In addition, these plastic plates are usually combined with ultraviolet absorbers to improve weather resistance, so crops such as eggplants and flowers that require ultraviolet rays or insects that require ultraviolet rays are powdered for crops such as cantaloupe and strawberry The cultivation is not suitable. In addition, the glass plate is liable to be broken. Due to the high weight of the glass plate, it is necessary to make the bone group of the greenhouse stronger. In order to solve these problems, for example, it is superior in weather durability and acid resistance, and has a service life of 10 to 15 years. It is proposed that it is more difficult to be polluted, and the dirt is easy to wash with rain, or has the advantage of being difficult to break Films of fluorocarbon resins made of tetrafluoroethylene-ethylene copolymer (hereinafter referred to as ETFE) or fluoroethylene polymers are used as covering materials for agriculture. Generally, films for covering materials for agriculture are stretched on In the case of a tubular greenhouse, the tensile force of the film is not loosened, and a fixing member is used to fix the bone group in the greenhouse. However, the fluorocarbon resin film used is inferior in flexibility due to its large modulus of elasticity, and it is necessary to stretch the film with a large force and fix it. In addition, the inside of the greenhouse is installed with a film 'for example, in the winter season ^ 1 ϋ ϋ 1 · ii I-ϋ yB gw n ϋ II ϋ ^ ϋ i «I (Please read the precautions on the back first $ write this page ) 111l · ^ &gt; L— — — — — — — The paper size of the paper is applicable to China National Standard (CNS) A4 (210 X 297 mm) -5- 568935 A7 B7 Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs V. Description of the invention (3) During the night and especially at night, the temperature in the greenhouse decreases during the period of time, in order to prevent the temperature in the greenhouse from falling sharply before it occurs, and in order to use the heater in the greenhouse The heating efficiency is improved for the user, and when excessive sunlight is used, it can be used to block part of the light in order to create an appropriate amount of sunlight. In this way, the film is installed inside the greenhouse during the day or in the evening, and it is stretched frequently in the morning and then contained. However, if the film is hard, it may be difficult to contain it and wrinkles may occur. DISCLOSURE OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, and to provide agriculture having a small modulus of elasticity and superior flexibility, compared with conventional fluorocarbon resin films, which has a small specific gravity and excellent stretchability. Used to cover materials. It can also provide agricultural covering materials for fluorocarbon resin films that are superior in flexibility and tensile strength.

The interior of the greenhouse used for agricultural and horticultural facilities is usually high temperature and high humidity. Condensed water droplets are easily attached to the inside of the ceiling or wall. The attached water droplets will shield the sun's rays, and if they are dropped, they will adhere to the plants in cultivation, which will prevent the good growth of the plants. Therefore, the contact angle of the film with water should be set to a small value. The contact angle of the film of the present invention with water is 106 degrees or less. The contact angle of the fluorocarbon resin film containing no hydrogen atom is not suitable because it exceeds 106 degrees. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. To prevent the adhesion of water droplets, it is advisable to treat the inside of the greenhouse with a drip solution. As for the dripping agent, examples include: an alcohol-soluble or water-dispersible fluorocarbon resin mixed with an inorganic hydrophilic colloid substance, a hydrophilic polymer mixed with a surfactant, and a hydrophilic polymer.
