Background technique

The occurrence, development and spread of building fires are mostly caused by a building material igniting, so the combustion performance of building materials is one of the important factors affecting building fires. With the development of science and technology, a large number of new building materials have been widely used. However, many building materials often do not have fire resistance. The fire caused a large number of casualties and property losses, with serious consequences.

Non-combustible board is a new type of building material that has emerged in recent years. Because of its beautiful appearance and thermal insulation advantages, it is widely used in various public place decoration, high-end home decoration, high-end furniture, high-speed EMU carriages, stadiums, etc. . However, the existing non-combustible boards have poor thermal insulation effect and cannot be used in some places with high fire protection requirements.

A combined non-combustible panel, which includes two panels and a filling cavity arranged between the two panels. One end of the two panels is hinged, and the other end is detachably connected by a hook and a slot. The inside of the panel is along the length There are honeycomb-shaped through-holes in the direction, and the through-holes are filled with stone powder and/or attapulgite powder and/or aluminum hydroxide powder, and the materials filled in adjacent through-holes are different. The phenolic resin covering the honeycomb-shaped through holes, the surface of the filling cavity is provided with a hook used in conjunction with the slot provided on the panel, and the filling cavity is divided into two parts for placing sound-absorbing materials and refractory materials respectively. There are two chambers, and the chamber for placing the refractory material is covered outside the chamber for placing the sound-absorbing material.

In some embodiments, the panel is covered with decorative paper.

In some more specific embodiments, the decorative paper is coated with melamine-formaldehyde resin.

In some embodiments, the weight of the phenolic resin is 30% of the weight of the non-combustible board.

In some embodiments, sealing strips are provided at the edges of the two panels.

In some embodiments, the sealing tape is a fireproof sealing tape.

Compared with the prior art, the utility model has the advantages of:

1. The utility model provides a combined non-combustible board, which not only has good heat insulation effect, is not easy to warp, but also has high tensile strength, and can be widely used in various public places with strict fire prevention and flame retardant requirements.

2. The composite non-combustible board provided by the utility model is not only light in material and simple in structure, but also cheap in raw material price, and can be widely used and popularized.

detailed description

In view of the deficiencies in the prior art, the inventor of this case has been able to propose the technical solution of the utility model through long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained in conjunction with the accompanying drawings and several embodiments as follows.

As shown in the figure: a combined non-combustible panel, which includes two panels 1 and a filling cavity 3 arranged between the two panels 1, one end of the two panels 1 is hinged, and the other end can be moved through a hook and a slot To disassemble the connection, the inside of the panel 1 is provided with a honeycomb-shaped through-hole 2 along the length direction, and the through-hole 2 is filled with stone powder and/or attapulgite powder and/or aluminum hydroxide powder, and the adjacent through-hole 2 The filling materials are different. The panel 1 is also filled with phenolic resin that can cover the honeycomb through hole 2. The surface of the filling cavity 3 is provided with a hook that cooperates with the slot provided on the panel 1. The filling The chamber 3 is divided into two chambers for placing the sound-absorbing material and the refractory material respectively through a partition, and the chamber for placing the refractory material is covered outside the chamber for placing the sound-absorbing material.

In some embodiments, the panel 1 is pasted with decorative paper.

In some more specific embodiments, the decorative paper is coated with melamine-formaldehyde resin.
