There is a growing need for windshields. In particular, the need for a glass coating composition is even greater in that it is not limited to the shape and width of the glass window by forming a film by easily applying to an existing glass window without the need for a separate vinyl coating operation.

However, in the conventional case, most of the light-shielding vinyl is used, and even in the case of the glass coating composition that has been developed, there is no example of maintaining a high visible light transmittance and greatly increasing the near-infrared light and UV blocking rate, and thus, satisfactory light blocking and light-transmitting effects could not be obtained. . In particular, there has been a great demand for the development of the near-infrared light, which has a light transmission profile that simultaneously transmits visible light to the uncoated glass window while simultaneously blocking the near-infrared transmittance and the ultraviolet light region of the 1,500 to 20,000 nm region. .

In addition, the smoothing performance during the glass coating is somewhat poor, the appearance of the coating is uneven, and even bubbles are generated, and improvements have been required.

In addition, there was a need for a function that can suppress the attraction of insects to places that are damaged by insects attracted by light, for example, places where food is stored and cleanness is essential. The need is great.

Therefore, the present invention is excellent in blocking the near infrared rays and ultraviolet rays while maintaining a high transmittance of visible light, compared to the conventional products, in particular, by increasing the blocking rate of a particular wavelength attracting insects, not only the effect of insect repellent, but also uniform An object of the present invention is to provide a glass coating composition, a film, and a method for producing the same, which greatly improve the smoothing function to enable glass coating of a thickness, and exhibit excellent effects in optical properties, weather resistance, and workability.

First, in the composition according to the present invention, it is important that the resin component is mixed with an acrylic polymer or an oligomer and an acrylic monomer to polymerize after coating to form a coating, and in the case of using only the acrylic polymer or oligomer or only monomer, a desired level Optical properties, workability and weather resistance of the can not be shown. In particular, by using a mixture of a polymer and a monomer at the same time as described above, in particular, the coating composition is smoothly adjusted as shown in Fig . 1 to maximize the effect of making the thickness of the coating uniform and improving the workability and weather resistance, etc. have.

In the case of the acrylic polymer of the present invention, it is preferable to use a weight average molecular weight of 10,000 to 200,000, more preferably 50,000 to 100,000 acrylic polymer. If it is out of the above range, the composition may not be easily adjusted, such as flowing the composition when applied to the glass, each may cause a problem that the smoothing is not made when applied to the glass.

If it is out of this range there may be a problem that does not achieve the desired optical properties, workability and weather resistance.

In the present invention, the acrylic polymer may be a polymer or oligomer polymerized from the acrylic monomer of the present invention, or may be derived from different acrylic monomers. In particular, in the acrylic resin of the present invention, which interacts with the silane compound of the present invention as described below, in order to increase the interaction, it is to include a hydroxyl group capable of forming a mutual bond with the silane functional group of the silane compound. More preferably, through the chemical bonds or interactions that do not lead to chemical bonds, the composition according to the present invention can be dried or cured to obtain an excellent effect of greatly increasing the weather resistance by reducing the crack of the coating coated on the glass.

Acrylic monomers according to the present invention include methyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate, butyl (meth) acrylate, isobutyl (meth) acrylate, pentyl (meth) acrylate, Preference is given to alkyl (meth) acrylates or mixtures thereof, such as hexyl (meth) acrylate, octyl (meth) acrylate, nonyl (meth) acrylate, lauryl (meth) acrylate and the like.

In addition, the silane compound used in this invention has two types, (iii) 1 or more types of organosilane compound chosen from tetraethoxysilane, (gamma) -aminopropyl trimethoxysilane, and its partial hydrolysis-condensation product, and (iv) amino At least one silane-based surfactant selected from silane, vinylbenzylsilane, and mercaptosilane.

These silane compounds, in addition to their respective functions, act optically and physicochemically with other components of the present invention such as the acrylic resin component of the present invention, ultraviolet and near-infrared absorbers, butyl acetate, methyl isobutyl ketone, ethylene glycol monobutyl, and the like. It has been confirmed by the present inventors as shown in the examples below to contribute greatly to improving weather resistance and the like.

It is preferable to obtain desirable optical properties. In particular, when an inorganic near-infrared absorber such as tin-doped indium oxide (ITO) or antimony-doped tin oxide (ATO) is used instead of one or more organic absorbents selected from phthalocyanine, naphthalocyanine, anthraquinone and squaric acid derivatives. By blocking ultraviolet rays and near infrared rays and absorbing visible light, it has been found that it is difficult to achieve the object of the present invention to obtain the most ideal shading and transmission profile.
