Description

Technical Field

[0001] The utility model relates to the technical field of wooden furniture, in particular to an effectively flame-retardant soundproof door. Background Art

[0002] The door core of solid wood composite door is mostly made of pine, fir or imported filling materials, and the density board and solid wood veneer are pasted on the outside. It is made after high-temperature hot pressing and sealed with solid wood lines. Generally, the door core of high-grade solid wood composite door is mostly high-quality white pine, and the surface is solid wood veneer. Because the white pine has a small density, light weight, and it is easier to control the moisture content, the weight of the finished door is lighter, and it is not easy to deform or crack. In addition, solid wood composite door also has the characteristics of heat preservation, impact resistance, flame retardancy, etc., and the sound insulation effect is basically the same as that of solid wood door. The full name of density board is density fiberboard. It is made of wood fiber or other plant fiber as raw material, prepared by fiber, applied with synthetic resin, and pressed under heating and pressurization. It can be divided into high-density fiberboard, medium-density fiberboard and low-density fiberboard according to its density. The density board is widely used in domestic furniture, decoration, musical instruments and packaging due to its uniform structure, fine material, stable performance, impact resistance and easy processing.

[0003] As people's requirements for living environment are getting higher and higher, for some special buildings, the rooms need to have good sound insulation and fire resistance. The commonly used wooden doors have no sound absorption effect and average sound insulation performance, and the surface is generally coated with flammable paint. Such wooden doors are very flammable. Once a fire occurs indoors, the wooden doors will fuel the fire, increase the difficulty of firefighting, and shorten the time for escape, posing a great safety hazard. Moreover, most of the wooden doors currently installed indoors have poor sound insulation effect, and the use of steel doors is relatively bulky, prone to resonance, and has poor sound absorption effect.

[0004] This case was created to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides an effective flame retardant soundproof door, which solves the problems raised in the above background technology.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: an effectively flame-retardant soundproof door, comprising a door panel, a multi-layer structure is arranged in the door panel, the middlemost layer in the door panel is a keel layer, a first flame-retardant layer and a sound insulation layer are fixedly connected on both sides of the keel layer, a second flame-retardant layer is arranged on the inner side of the first flame-retardant layer, and a moisture-proof layer is arranged on the outer side of the sound insulation layer.

[0009] Preferably, the keel layer is composed of transverse keels and vertical keels, the transverse keels and the vertical keels are perpendicular to each other, and multiple transverse keels and vertical keels are arranged at equal intervals, and the multiple transverse keels and vertical keels are rectangular structures.

[0010] Preferably, the upper and lower surfaces of the door panel are provided with hollow grooves, and sealing strips are provided in the hollow grooves.

[0012] Preferably, the first flame retardant layer and the second flame retardant layer are both coated with fire retardant paint and are both made of fire retardant material.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is an effectively flame-retardant soundproof door, which realizes multiple flame-retardant effects by setting a first flame-retardant layer and a second flame-retardant layer, and the flame-retardant layer is coated with fire-retardant paint, which is non-flammable. When a fire occurs, the contact area between the wooden board and the air can be reduced, effectively reducing the burning of the fire and achieving the flame-retardant effect. Sound-absorbing cotton is filled in the keel layer and the soundproof window, which greatly improves the door panel's ability to absorb volume and achieves the sound insulation effect.

[0019] The utility model is further described in detail below through the drawings and embodiments.

[0020] like Figure 1-3As shown: An effectively flame-retardant soundproof door, including a door panel 1, characterized in that: a multi-layer structure is arranged inside the door panel 1, the middlemost layer inside the door panel 1 is a keel layer 3, and the first flame-retardant layer 4 and the sound insulation layer 6 are fixedly connected on both sides of the keel layer 3, a second flame-retardant layer 5 is arranged on the inner side of the first flame-retardant layer 4, and a moisture-proof layer 7 is arranged on the outer side of the sound insulation layer 6. The first flame-retardant layer 4 and the second flame-retardant layer 5 can effectively reduce the probability of fire. Even if a fire occurs, the arrangement of the two flame-retardant layers can effectively prevent the fire from spreading rapidly.

[0021] The keel layer 3 is composed of a transverse keel 31 and a vertical keel 32. The transverse keel 31 and the vertical keel 32 are perpendicular to each other, and multiple transverse keels 31 and vertical keels 32 are arranged at equal intervals. The multiple transverse keels 31 and vertical keels 32 are a rectangular structure. The two layers of keels arranged perpendicular to each other can provide good support and fixation for the entire door panel, greatly enhancing the strength of the door panel.

[0022] The upper and lower surfaces of the door panel 1 are provided with hollow grooves 8, and sealing strips 9 are provided in the hollow grooves 8. The sealing strips 9 are made of materials such as expanded rock. When heated, they will expand and fill the gap between the door panel and the ground, playing a certain role in isolating smoke and dust, and can better play a protective role.

[0023] The keel layer 3 is filled with environmentally friendly sound insulation cotton, and the sound insulation layer 6 is filled with the same environmentally friendly sound insulation cotton. The double-layer sound insulation cotton makes it possible for the sound to be effectively absorbed after multiple reflections when penetrating the door panel, thereby achieving efficient sound insulation.

[0024] The first flame retardant layer 4 and the second flame retardant layer 5 are both coated with fire retardant paint and are made of fire retardant materials, which can reduce the contact area between the wood board and the air, effectively reduce the burning of the fire, and achieve the flame retardant effect. The thickness of the two flame retardant layers is 1-1.5cm.

[0025] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
