Description

Semi-noncombustible insulation board manufacturing apparatus {Apparatus for manufacturing quasi-noncombustible insulation steel board}

The present invention relates to an apparatus for manufacturing a semi-non-combustible insulation board, and more particularly, to an apparatus for manufacturing a semi-non-combustible insulation board capable of easily bonding a semi-non-combustible insulation sheet to a surface of a board.

In general, architectural finishing boards include an external finishing board used for the exterior of a building and an internal finishing board for finishing the inside of the building. Such finishing boards for construction should have functions suitable for the intended use, and in particular, interior finishing boards require functions such as flame retardancy (or non-combustibility) and sound absorption.

For the interior finishing board, rock wool, gypsum board, or plywood board is usually used. Among them, rock wool is rarely used at present due to controversy over the emission of carcinogenic substances.

In addition, the gypsum board has the advantages of being relatively inexpensive and not difficult to construct, but it is not easy to handle due to its heavy weight to strength and low impact resistance, and has disadvantages such as poor sound insulation and water resistance. In addition, although the fire resistance is strong, there is a disadvantage that the crystal water of the gypsum board is released when a fire occurs, and the wall is easily collapsed.

In addition, plywood board is light in weight, low in price, has strong impact resistance, and is easy to mix with other building materials, but has the disadvantage of being vulnerable to fire.

Therefore, in recent years, a board having a coating film formed on the surface of the board is used as a building finishing material such as a ceiling material. However, the conventional organic compound-based (epoxy resin, urethane resin, acrylic resin, etc.) paint composition for forming a coating film weakens bonding strength with the board, peels off due to differences in thermal expansion coefficient and elastic modulus, and swells in humid places. There is a problem in which problems such as a lifting phenomenon occur frequently. In addition, in a closed place such as an underground pit, the harmfulness caused by the release of volatile organic compounds is a problem.

Therefore, there is a need for continuous research and development for a semi-non-combustible insulation board that can be mass-produced while ensuring sufficient non-combustible and thermal insulation performance.

In addition, the cooling nozzle 171 is such that the middle portion corresponding to the center of the board (B) faces upstream with respect to the traveling direction of the board (B) relative to the end portions corresponding to both sides of the board (B). can be placed. For example, the cooling nozzle 171 may have a '∧' shape and may be disposed such that a sharp portion in the middle faces an upstream side from the center of the board (B). When the central portion of the board (B) is first cooled by the cooling nozzle 171 as described above, the temperature difference between the middle portion and the side end of the board (B) can be minimized, and accordingly, deformation and damage of the board (B) of course, it is possible to prevent the bonding surface with the semi-incombustible insulating sheet (S) from peeling off during the cooling process.
