Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating ceiling board and a method for manufacturing the same, and more particularly to a heat insulating ceiling board in which a reinforcing frame is bonded to the back 11 of the decorative board and a heat insulating material is disposed on the back side of the ceiling and a method for manufacturing the same. .

Conventional heat-insulating ceiling panels of this type are made by bonding decorative panels and reinforcing bars with vinyl acetate adhesive, and moisture in the adhesive causes the decorative panels and reinforcing bars to expand and contract, causing the ceiling to warp. It is likely that twisting will occur. Conventionally, the back side of the decorative board was filled with a heat insulating material after the decorative board and the reinforcing bar were bonded together, so gaps were likely to form between the heat insulating material and the reinforcing bar.

In some cases, sufficient insulation performance could not be obtained.

The present invention has been made in consideration of the above-mentioned points,
The main purpose of this is to bond the decorative board and reinforcing frame with water-free polyurethane resin, and to prevent the decorative IEK from warping or twisting.
However, for another purpose, the decorative board and the reinforcing crosspiece are bonded together at the same time while foaming the heat insulating material, thereby preventing the formation of a gap between the heat insulating material and the reinforcing crosspiece.
Our aim is to provide a heat insulating ceiling panel with good heat insulation properties, and by using the same polyurethane resin for the adhesive and heat insulating material, we can create a decorative board without interfering with the foaming of the heat insulating material. The purpose is to make the reinforcing beams K so that they can be glued together.

Embodiments of the present invention will be described below based on the figures [NC].The heat insulating ceiling 4N according to the present invention has a reinforcing crosspiece (21) bonded to the back surface of the decoration [+11] via a tan resin.

It is characterized in that a heat insulating material (3) made of polyurethane resin foam is filled over the entire 1fIK on the back side of the decorative board except for the part where the reinforcing crosspieces are installed.
The manufacturing method is to apply a polyurethane resin adhesive (9) to which a foaming material has been added over the entire back surface of the decorative board +1+, and then apply the polyurethane resin adhesive (9) to the back surface of the decorative board fi+ until the foaming of the polyurethane resin adhesive (9) is completed. Reinforcement crosspiece (!1t- pressure contact, makeup IF +
11 and the reinforcing bar (2) with a polyurethane resin adhesive (9).
It is characterized in that it is bonded by the adhesive and filled with the resin foam over the entire surface except for the 9 parts where the decorative 1'il+ll back surface is bonded. As shown in the figure, the reinforcing bar (21 is formed like a ladder by arranging horizontal bars (61) of KIN number between a pair of vertical bars (4). Third
As shown in the figure and FIG. A groove (8) is formed on the side surface over the entire length in the longitudinal direction.
8) Connect the ceiling panels by driving in joints (not shown).

A polyurethane resin adhesive (91) containing a foaming agent is applied over the entire surface of the back surface of the decorative board (1), and the reinforcing crosspiece 12 is adhered thereto. Decorative board 11) K reinforcement crosspiece 1!1
If you leave it for a while in the crimped state, the polyurethane resin adhesive (9) will harden and foam, and the decorative w (1) and reinforcing crosspiece (2) will be bonded together. Then, a heat insulating material (3) of polyurethane resin is formed by foaming on the back surface of the decorative board +l+ other than the part where the vertical bar (4) and the horizontal bar 111 are bonded.

In this way, *W and the insulation material (formation of 31) are combined into decorative board (1)

K, so it is done at the same time, so do you do it on the back side of the makeup IF +I+ other than the part where the reinforcing crosspiece (!) is glued? The heat insulating material (3) can be filled without any gaps.

<Example> 0.41 thick cedar slice single paddle is 2.7 all thick &l
Paste it on the surface of I to form a decorative board, and apply 1O of moisture-curing polyurethane resin adhesive with a foaming agent added to the back of the decorative board.
After applying at the ratio of f/l, apply the reinforcing bars formed on the die-cut material to the back side of the decorative board Kl! Placed.

The reinforcing beams are crimped until the foaming of the polyurethane resin adhesive is completed using a pressure of 0.0 calculated f/-, and the resin foam is filled without any gaps, resulting in an insulating ceiling board that does not warp or twist. A friend.

As described above, in the present invention, the decorative board and the reinforcing crosspiece are bonded using polyurethane resin, so the decorative board and the reinforcing crosspiece do not expand or contract due to moisture in the adhesive, and are free from warping or twisting. It has the advantage of being able to provide a heat-insulating ceiling board that does not require any heat insulation, and also has the advantage of being able to provide a double-walled ceiling board with decorative boards and reinforcing bars. Since the snow and the formation of the Wr thermal material are done at the same time using the polyurethane resin adhesive applied to the back side of the decorative board, the insulation material and the decorative board are in contrast, and the insulation material can be filled without any gaps, resulting in excellent insulation performance. It has the advantage of providing an insulated ceiling panel.
