Description

Detailed Description of the Invention (Technical Field) The present invention relates to a fibrous ceiling with a striped uneven pattern that is surface-painted on a fibrous ceiling board made of rockwar μ, su2goo, inn, etc. It's in the manufacturing method of the board.

(Background technique*) The conventional manufacturing method for a fibrous ceiling board with a striped uneven pattern is as shown in Figure 1, by cutting the surface of a fibrous ceiling board (A) coated with Rofkuu or Slagkuu. After giving the striped uneven pattern (c), it is common to spray water-soluble emulgene resin paint on the entire surface, and then dry it to form a fibrous ceiling print with the striped uneven pattern. It was spot on. However, in this manufacturing method, in order to form the striped uneven pattern (c) by cutting on the fibrous ceiling substrate (a), the raised surface of the convex part of the striped uneven pattern (c) becomes a rough surface, resulting in small holes. The upper surface of the convex part (1)
There was a drawback that color unevenness occurred between the surface and the standing surface (c).

C) The present invention has been developed in view of the above-mentioned background art, and provides a stripe-concave and convex pattern that eliminates color unevenness between the upper surface of the convex portion and the upright surface, thereby obtaining a uniform painted surface. 2. A method for manufacturing a fibrous ceiling board with an uneven pattern.

C) Disclosure of the Invention) Hereinafter, an embodiment of the present invention will be described based on FIGS. 2 and 3.

Rofukuuμ and slagoo! , the surface 2 of the fibrous ceiling substrate l on which 6 sheets of insulation were formed by a paper-forming method and dried.
The stripe uneven pattern 3 is created by cutting with a cutter.
After applying the water-soluble emulsion resin paint 4 to the entire surface 2 using an airless spray coating machine, apply the following amount:
() -100f//3o^60P is applied and then dried in a dryer using gas or infrared rays. After that, the raised surface 6 of the convex part 5 of the striped uneven pattern 1IA3 is polished by rotating a grindstone 7 so that the outer periphery has almost the same shape as the striped uneven pattern 3, thereby producing a fibrous ceiling board with a striped uneven pattern. 8 is a method for manufacturing a fibrous ceiling board with a striped uneven pattern.

At this time, sandpaper may be used to polish the upright surface 6 of the convex portion 5 of the striped concavo-convex pattern 3.

Therefore, after cutting the surface 2 of the fiber ceiling substrate 10 to give a striped uneven pattern 3, the entire surface of the striped uneven pattern 3 is painted and dried, and then the striped uneven pattern Ia3 is erected. Since the surface 6 is polished, even if the standing surface 6 after cutting is placed in a state where a small hole is formed, polishing will prevent the small hole from being caused by paint and polishing debris.
4) There is no color unevenness between the upper surface 9 of the convex portion 5 and the upright surface 6.

(Effects of the Invention) As described above, the present invention involves cutting the surface of a fibrous ceiling board to give it a striped uneven pattern, then painting the entire surface and drying it. Since the standing surface of the convex part is polished to form a fibrous ceiling board with a striped uneven pattern, even paint and polishing debris generated by polishing can be removed. Since it is packed, it becomes a smooth surface. Therefore, it is possible to obtain a uniform painted surface without color unevenness between the upper surface of the striped uneven pattern and the upright surface.
