Description

FIELD OF THE INVENTION [0001] The present invention relates to a fireproof-door fire-resistant intumescent sheet having an improved heat-

The present invention relates to a fire door having an expandable fireproof sheet with improved heat insulation and fire resistance, wherein a honeycomb-shaped reinforcement is formed inside a fire door frame formed of inner and outer panels to reinforce insulation and durability of the fire door, Fireproof sheets which are foamed and expanded by reacting at a temperature higher than a certain temperature between the panels are combined to prevent thermal deformation of the fire doors when the fire occurs and at the same time to cut off the fire quickly and also to improve the heat insulation, the soundproofing and the durability, To a fire door having an expandable fireproof sheet improved in heat insulation and fire resistance with improved productivity due to the manufacturing process.

Generally, fire doors are used as door openings for doorways or emergency passages such as general houses, buildings, apartments, factories, offices, and prefabricated buildings, and they are used to prevent external fire from spreading into the room, It is required to have a physical property requirement that doors and emergency doors should not be burned or deformed by strong internal heat in case of fire.

Especially, modern buildings, apartment buildings and apartment type factories are constructed as high-rise buildings, and the risk of fire occurrence is increasing a lot. If the fire and smoke are not prevented from spreading in case of fire, people living in high- , The role of installed fire doors is very important.

Such a fire door is generally manufactured by forming a non-combustible or flame-retardant reinforcement between the inner and outer panels. In order to reduce cost and facilitate fabrication, a gypsum board or asbestos has been used as a reinforcing material used in a conventional fire door.

However, stiffeners such as gypsum board and asbestos have caused severe damage to human body due to the continuous release of harmful substances such as environmental hormones, and in recent years environment-friendly materials have been used.

Accordingly, as disclosed in Korean Utility Model Registration No. 0434632, a flame retardant board (BB) using a material excluding a harmful substance such as paper, natural fiber, chemical fiber, etc. is used by being interposed between fire door panels.

However, such a flame retardant board has a relatively high manufacturing cost and has a merit in that the flame retardant board is simply arranged in a layered manner, but has a problem in that it is difficult to cope with heat insulation or soundproofing.

The present invention relates to a fire door having an expandable fireproof sheet with improved heat insulation and fire resistance, wherein a honeycomb-shaped reinforcement is formed inside a fire door frame formed of inner and outer panels to reinforce insulation and durability of the fire door, Fireproof sheets which are foamed and expanded by reacting at a temperature higher than a certain temperature between the panels are combined to prevent thermal deformation of the fire doors when the fire occurs and at the same time to cut off the fire quickly and also to improve the heat insulation, the soundproofing and the durability, It is an object of the present invention to provide a fire door having an expandable fireproof sheet improved in heat insulation and fire resistance with improved productivity due to the manufacturing process.

In order to achieve the above object, the present invention provides a plasma display panel comprising a frame (100) formed of an inner panel (110) of a non-flammable metal or synthetic resin and having an outer panel (120) spaced apart from the inner panel ; A reinforcing material 200 formed on the inner side of the frame 100 and made of a pulp mold or a flame-retardant synthetic resin material having a flame retardant treatment of paper or paper waste; And a refractory sheet 300 disposed between the reinforcing member 200 and the inner panel 110.

At this time, the stiffener 200 has a honeycomb shape in which a plurality of grooves having a square or hexagonal shape are continuously formed.

Further, the refractory sheet 300 is formed of a cellulose resin which is formed to expand and expand by reacting at a temperature of 170 to 220 ° C and expanding at a temperature of 550 ° C to a volume of 10 to 12 times.

As described above, according to the present invention, a honeycomb-shaped reinforcing material of an eco-friendly material is formed inside the fire door, thereby improving heat insulation, durability and soundproofing, as well as lightening the fire door.

In addition, a fireproof sheet that is foamed and expanded by reaction at a predetermined temperature is formed to prevent thermal deformation of the fire door when a fire occurs, to rapidly block the fire, and to form a sheet, It is effective.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the present invention mainly comprises a frame 100, a stiffener 200, and a refractory sheet 300.

At this time, the frame 100 includes an inner panel 110 formed of a non-combustible metal or synthetic resin, and an outer panel 120 spaced apart from the inner panel by a predetermined distance and corresponding to each other.

At this time, the inner panel 110 and the outer panel 120 may be formed by bending the rim portions so as to be coupled to each other or by joining separate rims, and the inner and outer panels may be separated from each other by a predetermined distance, It is preferable to fabricate the frame 100 so as to form a space.

The inner and outer panels are preferably formed of an aluminum alloy or a stainless steel metal material having excellent heat resistance and corrosion resistance, and may be used as a nonflammable synthetic resin material depending on the installation conditions.

1 to 3, the stiffener 200 is formed on the inner side of the frame 100 and is made of a pulp mold or a flame-retardant synthetic resin material having flame-retarding treatment of paper or waste paper.

As shown in FIG. 2, the reinforcing member 200 is formed in a hexagonal shape so as to improve durability, and is formed in a honeycomb shape in which a plurality of rectangular or hexagonal grooves are continuously formed.

That is, since the reinforcing member 200 has a honeycomb structure, heat loss according to the temperature difference between the indoor and the outdoor is minimized, and durability against thermal deformation or breakage of the fire door is improved during a fire.

4, the refractory sheet 300 is disposed between the reinforcing member 200 and the inner panel 110. As shown in FIG.

At this time, the refractory sheet 300 is formed of a cellulose resin which is formed to foam and expand at a temperature of 170 to 220 ° C, and expanded at a temperature of 550 ° C to 10 to 12 times the volume.

In addition, the refractory sheet 300 can be used in a structure in which one or more refractory sheets are laminated for the purpose of reinforcing heat insulation and fire resistance, and also can be disposed between the reinforcing material 200 and the outer panel 120, As shown in FIG.

As shown in FIG. 4, the refractory sheet 300 is maintained in a flat sheet form (a) at room temperature and is deformed into a foamed and expanded form (b) by heating at the above- The foamed and inflated portion is filled into the inside of the reinforcing member 200 to prevent thermal deformation of the fire door and to prevent fire from spreading due to fire resistance.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
