等の欠点があった。2. Description of the Related Art Conventionally, when coating an inorganic building material having a cosmetic joint such as a groove on the surface, after applying an unnecessarily large amount of paint to the whole by flow coater coating, spray coating, shower coating, or the like. A method of spraying air onto a panel to spread the paint has been proposed.
In the case of coating using a flow coater, if the coating amount is small, the groove slope portion having a vertical or nearly vertical angle cannot be coated sufficiently. In addition, in order to apply this vertical or near vertical groove-like decorative joint, it is necessary to increase the application amount by widening the slit width and slowing the transport speed. There are drawbacks such as the loss of the design of the pattern and the lengthening of the drying equipment.

However, in the case of a spray coat, the paint is atomized and atomized, so that the paint is scattered in the air and the coating efficiency is reduced. There was a problem. In addition, since it is necessary to install a spray gun on each of the uneven surfaces also on the equipment side, there is a problem that the equipment becomes complicated. Even after spraying the paint on the surface with a shower coat or the like and spraying the paint by spraying air, if the paint is not filled in the bubbles on the slope, the paint on the bubbles is scraped off. There are drawbacks such as the occurrence of pinholes and poor waterproofness.

A coating method for an inorganic building material, characterized by flowing paint in a curtain form from a slit of a flow coater having an angle of not less than 85 ° and not more than 85 °. 2) The use of a flow coater to convey and coat an inorganic building material having a grooved decorative joint formed at an angle of 5 ° to 85 ° with respect to the conveying direction, and painting the inorganic building material. Painting method. 3) An inorganic building material coated by the coating method described in 1) or 2). 4) A coating apparatus having a slit that forms an angle of 30 ° or more and 85 ° or less with respect to the transport direction, and through which the paint can flow in a curtain shape.

If the angle is less than 30 °, painting on the slope can be performed without any problem, but it is difficult to maintain the stability of the curtain because the required curtain length is long depending on the width of the inorganic building material. . If the angle is greater than 85 °, the slope cannot be painted. A particularly preferable range of the angle of the slit with respect to the transport direction is 40 ° or more and 60 ° or less.

The range is 5 ° or less. When the angle of the slope is 60 ° or more, reciprocating painting using the same slit can not be applied to the surface where the vertical direction of the slope faces the opposite side to the conveyance direction without leaving any paint on the slope. Alternatively, it is preferable that the panel is rotated by 180 ° after the first coating, and then the second coating is performed, which is another coating.

Further, the type of the paint is not particularly specified, and the surface of the inorganic building material may be treated before painting with a flow coater. Examples of the inorganic building material in the present invention include a ceramic siding material, a slate plate, a calcium silicate plate, and an autoclave-cured lightweight cellular concrete plate.

明する。[0009] The flow coater coating apparatus does not atomize the paint unlike the spray method, and therefore has excellent coating efficiency and recovery efficiency as generally known. Also, after painting with a flow coater, the coating film is cut off in order not to spray the air and spread the paint, etc.
The lower substrate surface is not exposed and no equipment other than a flow coater is required, so that the equipment is simple. An example in which the present invention is applied to a method for coating a lightweight cellular concrete panel cured by an autoclave will be described below.
