Description

FIELD OF THE INVENTION [0001] The present invention relates to a flame-

The present invention relates to a vegetation board for planting plants and a method of manufacturing the same, and relates to a vegetation board having at least flame resistance by a flame-retarding treatment according to one embodiment and a method of manufacturing the same.

Recording can improve the residential environment. Thus, for example, in buildings such as apartments and buildings, the wall surface is progressing. Wall-screening is beneficial not only to give nature-friendly appearance to buildings but also to reduce environmental pollutants such as fine dusts.

The most classic method of wall-tinting is to plant plants such as ivy on the ground or pollen to climb on the wall. However, this limits the kinds of plants that can be planted and is somewhat difficult to apply indoors. In addition, attempts have been made to use vegetable bricks of concrete as a material, but in this case, it is pointed out that the vegetable bricks are heavy and the installation work (construction work) is difficult and costly.

Recently, a method of using vegetation boards has been proposed and is being preferred. As the vegetation board, carbonized cork board and wood board are used, among which carbonized cork board is useful. For example, Korean Patent No. 10-0934787, Korean Patent No. 10-1218111, Korean Patent No. 10-1238336, and Korean Patent No. 10-1757854 disclose techniques related to the above.

Generally, a carbonized cork board is produced by carbonizing and crushing an endothelium having a honeycomb structure of a natural cork tree to obtain carbonized cork particles and then pressing them. This carbonized cork board is an environmentally friendly natural material that is light and suitable for plant growth, and is very useful as a vegetation board for indoor greening as well as for wall surface of a building. In addition, the carbonized cork board provides its own beautiful appearance (natural cork pattern, etc.).

However, carbonized cork board is a suitable material for plant growth, but it is vulnerable to heat (flame). Carbonized cork boards can be deformed or burned by heat (flame), for example, when a fire occurs. In addition, the carbonized cork board tends to be corrupted or damaged by microorganisms or insects, resulting in poor durability.
