Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rock wool decorative finishing material having flexibility by forming slit grooves having a groove width of 1 mm or less on the back side so as to be able to follow irregularities on a construction surface. The present invention relates to a method for forming a slit groove on the back surface side of a rock wool decorative material and an apparatus for forming the groove.

[0002]

2. Description of the Related Art Conventionally, when a rock wool decorative finish material such as a ceiling material or a wall material is applied to a plaster board, a plywood disposal material, a wood substrate, a light iron substrate, etc., the surface is uneven or swelled. Even if there is a misalignment, the makeup finishing material is placed along the base material, so that the makeup finishing material is placed along the curved base material to form a curved ceiling / curved wall, etc. A cutting groove having a groove width of 1 mm or more is provided on the back surface so that the decorative finish has flexibility.

However, even if the rock wool decorative material is an incombustible or quasi-incombustible material, if a cutting groove having a wide groove width of 1 mm or more is provided as described above, the material lacks and becomes a void. The material becomes thin in the part, and there is a drawback that this part becomes a weak point in fire prevention.

If the rock wool decorative material is to have flexibility, it is sufficient that the back surface side has only a cut, and a cutting groove having a wide opening is not necessary. Therefore, it is better to make the opening width of the groove as small as possible, but cutting the groove with a conventional router or cutter will not only result in a groove width more than the thickness of the tool (at least about 1 mm), but also If it is bad, the fibers may be scraped off by the blade and chips may occur at the corners. In particular,
This is remarkable when the rotating direction of the blade is rotating so as to be in the conveying direction of the rock wool decorative material.

Further, when the groove of the rock wool decorative material is cut with a conventional cutter or router, a large amount of fine fibers and powder are generated because the material is scraped off by the blade. Since these are non-combustible substances, they cannot be incinerated, which causes a treatment problem as industrial waste.

Further, although the rock wool decorative material is soft and easy to cut, the above-mentioned fine fibers and powders are mainly composed of raw materials having high hardness such as silica and alumina. Rotation (5,000 rp
There is also a manufacturing problem that the blade rotating in m) becomes as if it were polished by these high hardness substances, which significantly shortens the life of the blade. Therefore, when an expensive diamond blade with excellent wear resistance is used, the point of wear is improved, but if a hard foreign substance is mixed in the rock wool decorative material, the diamond cutting edge will be chipped. On the contrary, there is a problem that it cannot be used.

[0007]

The problems to be solved by the present invention are as follows.
In the case of rock wool decorative finishing material itself, it is to solve both the defect of fire prevention and the addition of flexibility, and the grooved method enables to form slit grooves neatly without chipping. In the grooving device, no industrial waste is generated at the time of groove formation, and even if it is not a diamond blade but a normal blade, its life is not impaired. That is, when forming the groove, no damage occurs in the rock wool decorative finish material.
