[Detailed Description of the Invention] (1) Purpose of the Invention Regarding a method for manufacturing an inorganic building board containing cement as a main component,
The purpose of the present invention is to provide a method for manufacturing an inorganic building board with an uneven pattern.

(2) Conventional Example Inorganic building boards whose main component is a hydraulic material such as cement have been known for some time. Additionally, textured patterns were also added to this inorganic building board. Conventional methods for imparting an uneven pattern include using a press or roll, pasting a decorative sheet, and painting. However, these methods have drawbacks such as requiring large-scale equipment, difficulty in setting the conditions for producing fogginess (as in the eyelid method), and high product costs.

The drawings are schematic diagrams illustrating the steps of the invention. In this figure, 1 is a green sheet, 2 is a feeder, 3 is dehydrated ettringite particles, 4 is a pair of rolls, 5 is a flow coater for applying water-based paint, 6 is a dryer, and 7 is a product. First, in (a), a green sheet is prepared. This green sea) 1 may be made by any method. For example, the polarity of the method, such as paper making method or casting method, does not matter. Next work &! (b) Place feeder 2 on top of green sheet 1.
The particles 3 are supplied and dispersed. In the next step (c), the particles are forced into the green sheet 1 by the roll 4. However, this process is not necessarily a summary. In the next step), a water-based paint 8 is applied by a flow coater 5. It is then dried in step (e). For the first time in the previous steps, the dehydrated ettringite particles 3 sufficiently absorb water, crystallize, and swell to make the surface of the plate uneven. This 1ζ7 forms an uneven pattern. Furthermore, if the base plate is compatible with ettringite, the uneven pattern and the base will be firmly bonded. The coating film formed on the surface of the product serves to protect the uneven pattern. Water-based paint is used because the material is hydraulic. The size of the dehydrated ettringite particles 3 to be sprinkled,
The density of spreading, the manner of spreading, etc. may vary depending on the desired pattern.

(4) Example Particles of dehydrated ettringite were sprinkled on the surface of a cement green sheet containing ettringite. The particles used had an average particle size of 1.6 mm. Next, after pushing the particles into the surface of the green sheet with a roll, a water-based paint (V-Selan #300 manufactured by Dainippon Toyo Co., Ltd.) was applied. When it was then dried, it was replaced with a construction board that had a relatively large-scale uneven pattern on its surface.
