Embodiment 1

[0054] An inorganic cationic colloid sol was prepared by mixing 331.3 parts of water and 740.7 parts of a cationic alumina sol (X1-1) (solid content: 13.5%). 8 parts of the silanol-forming organosilane compound (Y-1) were mixed with this inorganic cationic colloidal sol to prepare a mixed liquid having a solid content concentration of 10%, and stirred at 50° C. for 5 hours for the silanol-forming organosilane compound (Y-1). -1) A hydrolysis treatment is performed, and the generated silanol compound is further polycondensed to obtain a modified inorganic cationic colloidal sol (A-1). The modified inorganic cationic colloidal sol (A-1) is obtained by adhering a polycondensate of a silanol compound to the solid content particles of the above-mentioned inorganic cationic colloidal sol. Next, 8900 parts of water, 30 parts of polyether-modified silicone (B-1), polyoxyalkylene derivative ( 10 parts of C-1) and 60 parts of ethylene oxide-propylene oxide block polymer (D-1) were stir...

Embodiment 38

[0120] The ethylene·1-butene copolymer (ethylene copolymerization ratio 96%, density 0.930g / cm 3 , MFR1.0g / 10 minutes) were given to the inflation molding machine equipped with a die head with a diameter of 75mm and a die lip gap of 3mm, and inflation molding was carried out under the conditions of resin extrusion temperature 200°C and BUR=1.8, making An olefin polymer film with a thickness of 150 μm was produced. Next, corona treatment discharge was performed on the olefin polymer film, and after the wetting tension of the corona discharge treatment surface was set to 44 mN / m, the thermoplastic polymer film prepared in test group 1 was coated by the gravure printing method. Composition (S-1) is 0.3 g / m in terms of solid content 2 It was applied to the corona discharge-treated surface, and was left in a hot-air drying oven adjusted to 70° C. for 1 minute to obtain the modified thermoplastic polymer film of each example.

Abstract

The present invention provides a composition for coating a thermoplastic polymer film, a method for producing the composition, a modified thermoplastic polymer film using the composition, and a method for producing the modified thermoplastic polymer film, even in a dry state. In the case of repeating the wet state, it can also exhibit excellent dripping properties from the initial stage after spreading, and can maintain excellent dripping properties for a long time after spreading, and also has excellent scratch resistance. There is very little stickiness on the film surface. As a composition for coating a thermoplastic polymer film, a specific (modified) inorganic cationic colloid sol, a polyether-modified silicone, a specific polyoxyalkylene derivative, and a specific ethylene oxide-propylene oxide interlayer are used in a specific ratio. Compositions made of segmented polymers.

Description

technical field [0001] The present invention relates to a composition for coating a thermoplastic polymer film capable of imparting durable dripping properties to a film for agricultural greenhouses, a method for producing the composition, a modified thermoplastic polymer film using the composition, and the modified A method for producing a thermoplastic polymer film. Background technique [0002] As a covering material for agricultural greenhouses, thermoplastic polymer films are widely used. However, since the thermoplastic polymer film has hydrophobic properties, when fogging occurs and the penetration of sunlight decreases, the growth of crops becomes poor, and there are also problems such as dripping of attached water droplets and generation of diseases. Therefore, in the past, it has been proposed to add a nonionic surfactant as an antifogging agent in the film for agricultural greenhouses, or to attach a reagent mainly composed of colloidal silica and colloidal alumi...
