As a means for solving this problem, functional glass such as optical special glass, that is, low-E glass, is being installed, but only a part of it is being installed due to high cost of the equipment.

As the heat insulating and heat shielding means generally used, a functional film adhered to a glass surface is provided. However, in the case of the functional film, it is impossible to construct the type plate glass, the material is easily scratched due to its characteristics, There is a disadvantage that the adiabatic effect deteriorates over time.

The present invention relates to an energy-saving coating agent capable of effectively blocking infrared rays and ultraviolet rays while enhancing heat insulation and heat shielding effect. The present invention also relates to an energy-saving coating agent for shielding infrared rays and ultraviolet rays, And there is a disadvantage that the transparency is insufficient and the viewability is not satisfactory.

Patent No. 10-0933526 "Energy-saving transparent coating material used for coating building materials and method for forming coating film using the same Patent No. 10-1013123 "Energy saving coating composition and coating method using the same" Patent No. 10-1065618 entitled "Ultraviolet and Infrared ray shielding powder and method for producing the same, glass and coating agent including ultraviolet ray and infrared ray shielding powder, and method for producing glass and coating agent thereof" Published Japanese Patent Application No. 10-2013-0066772 "A method for producing a coating solution based on nanotechnology which is coated on a glass material to block ultraviolet rays and infrared rays and generate adiabatic and heat-shielding effects

The present invention relates to a method of manufacturing an energy saving transparent coating material having excellent heat shielding function as well as infrared ray and ultraviolet ray shielding. In particular, the present invention relates to a transparent coating material having excellent transparency, So that anyone can easily construct it.

In order to achieve the above object, the present invention provides a transparent coating material for an energy saving transparent coating material, which comprises a binder resin which imparts a heat insulating property and an adhesion property between composition components of a transparent coating material and a binder resin which absorbs infrared rays and ultraviolet rays, (ATO) -based inorganic pigment, and a solvent for facilitating the mixing between the composition and the concentration control, wherein the mixing ratio of the binder resin is from 23 to 89.5 By weight of an inorganic pigment, 7.5 to 60% by weight of an inorganic pigment, and 0.5 to 25% by weight of a solvent.

The present invention relates to a transparent paint which is an energy-saving transparent paint, wherein a composition component of the transparent paint comprises a binder resin which imparts heat insulation and adhesion between the composition, ITO which absorbs infrared rays and ultraviolet rays and imparts fine color to the glass oxide and ATO (antimony tin oxide) based inorganic pigments, and a solvent for facilitating the mixing between the concentration control and the constituent components. The mixing ratio of the constituent components is 23 to 89.5% by weight of the binder resin, A transparent paint of energy saving type is prepared by mixing 7.5 to 60% by weight of a solvent and 0.5 to 25% by weight of a solvent, and is applied to a glass surface to be heat-treated to improve transparency, thereby ensuring visibility, There is no reflection pollution, and the transparent paint can be easily installed by anyone.

Hereinafter, a method of manufacturing an energy-saving transparent paint to be provided in the present invention will be described.

The energy saving transparent coating material to be provided in the present invention is obtained by mixing 23 to 89.5% by weight of a binder, 7.5 to 60% by weight of an inorganic pigment and 0.5 to 20% by weight of a solvent to obtain a liquid composition, By coating the paint on the glass surface and drying it, it is possible to obtain a function of not only infrared ray and ultraviolet ray shielding but also excellent heat ray transparency and visible light transmittance.

In the above, the binder is required to maintain the heat insulating property and the appropriate thickness, and to maintain the adhesion between the composition components and the adhesive strength upon application to the glass surface, and to maintain necessary hardness after curing.

A silicone binder and an acrylic binder may be used in combination as a binder for maintaining the above conditions, or a binder selected from the two may be used alone.

In addition, the amount of the binder used in the transparent paint composition is in the range of 23 to 89.5% by weight based on the total amount. When the total amount of the binder used is less than 23%, not only the heat- And if it is more than 89.5% by weight, the total amount of the inorganic pigment and the solvent to be added is reduced, so that the infrared ray or ultraviolet ray shielding function is deteriorated, which is not preferable.

Inorganic pigments such as ITO (indium tin oxide) -based inorganic pigments and ATO (antimony tin oxide) -based inorganic pigments can be selected as the inorganic pigments. In addition, the inorganic pigments are imparted with a pale color and effectively shield infrared rays and ultraviolet rays. Good.

The amount of the inorganic pigment to be used in the composition is in the range of 7.5 to 60% by weight based on the total amount. If the total amount of the pigment to be used is less than 7.5%, the blocking function of infrared rays and ultraviolet rays is lowered. The amount of the binder used is relatively reduced, so that the adhesiveness between the heat insulating property and the glass surface is deteriorated and the durability is weakened.

The solvent is used as an additive to improve the coating property while maintaining proper viscosity of the transparent paint to be produced. The amount of the solvent used is in the range of 0.5 to 0.25% by weight based on the total amount of the solvent. Ethyl acetate, toluene, , Methyl isobutyl ketone, acetone, methyl ethyl ketone, oligomers such as epoxy acrylate, urethane acrylate, silicone acrylate, and polybutadiene acrylate, and a small amount of a leveling agent.

If the amount of the solvent used is less than 0.5%, the coating property is deteriorated. If the solvent is used in an amount of 25% or more, the transparent paint is too thin to easily flow on the glass surface and the amount of the binder or inorganic pigment is reduced. Heat shielding, ultraviolet rays, and infrared rays are deteriorated.

Hereinafter, embodiments of the present invention will be described in detail.

An energy-saving transparent coating material was prepared using the compositional ingredients as shown in Table 1 described below, and then the transparent coating material was coated on the glass surface to form a transparent coating layer.
