Purpose of the invention [Field of industrial application] This invention relates to a ceiling board in which an uneven pattern is provided on the surface of a low-density board formed mainly from mineral fibers such as rock wool and mineral fiber. In particular, the object is to obtain a ceiling board with improved physical properties of the surface of the uneven pattern.

Conventionally, short fibers such as rock wool or mineral wool, water-soluble and water-dispersible binders, fillers, auxiliary agents, etc. are mixed with water to form a paste-like material that can be plastically deformed, and this is then extruded or rolled. It is very common practice to produce relatively low density fiberboards by forming them into plates and drying and curing them.

も行なわれている。 According to the above-mentioned paste method, by applying a rubbing process to the surface of the plate during molding, a travertine pattern that is close to natural can be imparted, and this travertine pattern ceiling board is manufactured in extremely large quantities.
In order to enhance the design of the plate, pattern-shaped recesses are provided by secondary cutting to create a three-dimensional pattern on the surface.

Mineral fiber board made by the paste method mentioned above is 0.3-0.5
Due to its low density, sound absorption, heat insulation, fire prevention, and dew prevention properties, it is extremely suitable for ceiling panels.However, after the drying and curing process during normal manufacturing, the front and back surfaces are cut to give a smooth finish. The original plate needs to be a thick plate that takes into account the finishing allowance, and if recesses are to be cut into the surface, it is necessary to increase the thickness to maintain strength. In addition to lowering the yield of raw materials during manufacturing and increasing processing costs such as drying and cutting, the surface of the board is the same soft tissue as the inside and is susceptible to external damage, so the uneven pattern conditions must be extremely limited. It didn't happen.

模様を残存せしめることができる。 As a starting material for sheet manufacturing, a paste-like material that can be plastically deformed to the extent that it does not naturally flow is used by kneading mineral fibers, water-soluble and water-dispersible binders, fillers, and other auxiliaries with water in the paste method. After forming this into a plate shape by extrusion or rolling, if necessary, the surface is rubbed to form travertine-like surface cracks and small depressions on the surface, and an embossing roller is pressed onto the surface of the plate. , a concave portion and a convex portion having the above-mentioned area ratio are formed. According to this embossing process, a convex portion corresponding to the volume of the recess can be formed without causing excessive local compression due to plastic deformation of the material. Therefore, even if a travertine pattern is provided, the pattern can remain, although it will be deformed to some extent.

As water evaporates from the surface as it dries, the aqueous binder is mainly transferred to the surface, forming a hard skin layer with a high binder content, usually less than 1 mm in thickness, on the embossed uneven pattern surface. is formed to obtain the product of the present invention.

As mentioned above, the ceiling board of the present invention is composed of a low-density base layer with a hard skin layer with a high binder content that is integrally laminated and bonded to the entire surface of the uneven pattern, so it suppresses the decrease in strength due to uneven molding. At the same time, the hardness and strength of the surface of the pattern can be improved, the degree of freedom in pattern selection conditions can be expanded, and it is possible to achieve excellent design properties as well as performance such as sound absorption, heat insulation, fire prevention, moisture absorption, and stain resistance.
