Description

Fire-proof door

Technical Field

The utility model belongs to the technical field of the fire control building materials technique and specifically relates to relate to prevent fire door.

Background

A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. The fireproof partition is arranged in fireproof partitions, evacuation staircases, vertical shafts and the like and has certain fire resistance, and the fireproof door has the functions of preventing fire from spreading and smoke from diffusing besides the function of a common door, can prevent the fire from spreading within a certain time and ensures personnel evacuation. The fireproof door in the market at present comprises a fireproof core plate and a fireproof facing layer for coating the fireproof core plate, wherein the fireproof core plate of the fireproof door takes aluminum silicate cotton as a main material, and the generated smoke has toxicity; the fire-proof core board of the fire-proof door uses expanded pearl rock wool as a main material, and has poor strength and fire-proof combustion performance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent fire door for solve the above-mentioned technical problem who exists among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme:

prevent fire door, including door frame and the door leaf panel of cooperation setting in the door frame, the door leaf panel includes the fire-retardant layer of both sides and presss from both sides the flame retardant coating of establishing in the middle of fire-retardant layer, the flame retardant coating adopts polylith silicon magnesium PLASTIC LAMINATED concatenation to form, and adjacent two fill fire prevention daub in the concatenation seam between the silicon magnesium PLASTIC LAMINATED.

In a preferred embodiment, the flame retardant layer comprises a substrate and a layer of a fire retardant coating coated on the substrate; the substrate is a phenolic aldehyde plate.

In a preferred embodiment, the width of the splice seam is 5-8 cm.

In a preferred embodiment, the fire-proof layer and the flame-retardant layers on the two sides are bonded and compounded into a whole through an adhesive layer; the adhesive layer is epoxy resin adhesive or polyurethane adhesive.

In a preferred embodiment, the door frame further comprises a fireproof expansion sealing strip, and the fireproof expansion sealing strip is embedded in the peripheral edge, which is in contact with the door leaf panel, of the door frame.

Compared with the prior art, the utility model, prevent fire door, its beneficial effect lies in: the utility model discloses simple structure, the cost of manufacture is low, compares with traditional fire door, has effectively improved fire door's fire behavior, and the usage is extensive, and production efficiency is high, installation convenient to use, matter is light moreover, the environmental protection is pollution-free, accords with the condition demand of engineering, possesses excellent actual value of using widely.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic side sectional view of a door leaf panel of the fireproof door of the present invention;

fig. 2 is a schematic view of the fireproof layer structure of the fireproof door of the present invention.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

According to fig. 1-2, the fire door of the present invention is illustrated, which comprises a door frame and a door leaf panel disposed in the door frame, wherein the door leaf panel comprises two fire-retardant layers 1 disposed at two sides and a fire-retardant layer 2 disposed between the fire-retardant layers 1, the fire-retardant layer 2 is formed by splicing multiple silicon-magnesium fire-retardant plates 201, and a fire-retardant daub 202 is filled in the splicing seam between two adjacent silicon-magnesium fire-retardant plates 201. The glass magnesium fireproof plate 201 has the functions of high temperature resistance, flame retardance, fire prevention, sound absorption, shock prevention and the like, is light in weight and can be adhered, and is suitable for the field of fire-fighting building materials. And with the concatenation of the above-mentioned glass magnesium PLASTIC LAMINATED 201 of polylith, pack fire prevention daub 202 in the concatenation seam, compare in traditional monoblock PLASTIC LAMINATED, can effectively prevent stretching of intensity of a fire, slow down the speed that the flame stretchs, play the effect of effective fire prevention.

In addition, the width of above-mentioned concatenation seam if too wide, then can influence whole fire door's intensity, if the width is too narrow, then can not play better fire prevention effect, the utility model discloses the width of preferred above-mentioned concatenation seam is 5-8cm, and this width can guarantee fire door's intensity, can effectively improve fire behavior simultaneously.

The flame-retardant layer 1 comprises a substrate 101 and a fireproof coating layer 102 coated on the substrate 101; the substrate 101 is a phenolic plate. The phenolic aldehyde plate has excellent performances of heat preservation, fire prevention, light weight, no toxicity and the like, so that the whole fireproof door is light in weight, good in fireproof performance, environment-friendly and pollution-free.

The preferable structure of the utility model is that the fire-proof layer 2 and the flame-retardant layers 1 at the two sides are bonded and compounded into a whole through the adhesive layer; the adhesive layer is preferably an epoxy adhesive or a polyurethane adhesive.

In order to further resist flame, the door frame also comprises fireproof expansion sealing strips, and the fireproof expansion sealing strips are embedded in the peripheral edges of the door frame, which are contacted with the door leaf panels. Above-mentioned fire prevention sealing strip is met the thermal after inflation, with the close shutoff in the gap between door frame and the door leaf panel, can prevent effectively that flame from boring into from the gap, extension fire-resistant time increases the fire prevention effect.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
