DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tobacco odor deodorizing coating composition, and more particularly to a tobacco odor deodorizing coating composition useful for removing tobacco odor.

[0002]

2. Description of the Related Art Conventionally, smoking has a long history and has been widely used, but in recent years, the health problems of smokers and those around them have been highlighted. As important as this is the problem of tobacco odor. For example, when smoking in a relatively small space in a passenger car or in a house, tobacco odor remains even when smoke is invisible, and odors and dirt are stained on the indoor walls and furniture for a long time, There is a problem that an unpleasant tobacco smell is felt even without smoking.

[0003] This problem is particularly remarkable in a room such as a passenger car having a small space. As a method for solving such a problem, a method of placing activated carbon having a large adsorptive power in a room and absorbing and removing odor has been performed.However, the ability of activated carbon to remove tobacco odor is low, and a sufficient deodorizing effect can be obtained. Not. Therefore, an object of the present invention is to provide a deodorizing paint in which the generated tobacco odor is easily absorbed and removed even when smoking is performed in a small room such as a passenger car.

[0004]

The above object is achieved by the present invention described below. That is, the present invention provides a deodorizing paint comprising a binder resin, a deodorizing component, and a liquid medium, wherein the deodorizing component comprises (1) vegetable oil and / or a fatty acid thereof ;
(2) zinc compounds, other organic acids, activated carbon, zeolites and
A tobacco odor deodorizing coating composition comprising at least one selected from aluminum and aluminum salts .

[0005]

It has been found that a coating film composed of a paint containing vegetable oils and / or their fatty acids absorbs and removes the tobacco odor very efficiently. By coloring these paints to the required hue and applying them to indoor floors, ceilings and walls, etc., the contact surface between the tobacco odor and the coating film becomes very large, and the tobacco odor is quickly absorbed and removed. You. When the tobacco odor absorbing ability of the coating film is saturated, the deodorizing effect can be easily restored by coating the film repeatedly or by making the film easily peelable and re-painting.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Next, the present invention will be described in more detail with reference to preferred embodiments. As the binder resin used in the paint of the present invention, any binder resin used in conventional water-based paints and oil-based paints may be used, but in consideration of workability, safety, etc., water-soluble to water-soluble hydrophilic Acrylic resin, vinyl resin, polyurethane resin and the like are preferable, and it is desirable to use them in the form of an aqueous solution or emulsion.
