As shown in fig. 1, the fire-proof wooden door includes a door leaf 20 and a door frame 10, wherein the door frame 10 can be mounted on a base layer 30, the door leaf 20 is rotatably mounted on the door frame 10, and the base layer 30 can be a masonry structure or a concrete structure. The fire-proof patch 100 may be installed on the door leaf 20, or the fire-proof patch 100 may be installed on the door frame 10, or the fire-proof patches 100 may be installed on both the door leaf 20 and the door frame 10, in order to enhance the fire-proof performance of the wooden fire-proof door and to take the decorative aesthetic property of the wooden fire-proof door into consideration, as shown in fig. 1, in some embodiments, the fire-proof patch 100 may be installed on the surface of the door frame 10. The following will be described in detail mainly with reference to an embodiment in which the fire patch 100 is installed on the surface of the doorframe 10.
It should be noted that, in order to enhance the fire-proof performance of the joint between the door frame 10 and the door leaf 20, the fire-proof patch 100 may be installed on the surface of the joint between the door frame 10 and the door leaf 20 to prevent the flame and heat from spreading along the joint, thereby further improving the fire endurance of the wooden fire-proof door. It is understood that the fire-blocking patch 100 may be applied to other configurations where enhanced fire-blocking is desired. The fire patch 100 may be directly attached to the surface of the fire door by an adhesive, or may be indirectly attached to the surface of the fire door, which is not limited herein.
More specifically, since the direction of the hot air flow formed by the flame is upward, relatively speaking, the temperature above the wooden fire door is higher than that below the wooden fire door, and the joint of the upper edges of the door frame 10 and the door leaf 20 is in the hot air flow, so that the door frame 10 and the door leaf 20 are burned through along the joint, which is the most common in a fire disaster, on the basis of which, in order to save cost and ensure fire resistance, the fire-proof patch 100 can be arranged at the joint of the upper edges of the door frame 10 and the door leaf 20. As shown in fig. 1, the door frame 10 includes an upper beam 11 having a first side surface 11a facing the indoor and a seam forming surface 11b facing the door 20, and the fire protection sheet 100 is disposed on the first side surface 11a and the seam forming surface 11 b.
In an embodiment of the present invention, as shown in fig. 1 to 2, the fire patch 100 includes an aerogel layer 120, a flame retardant plastic layer 110, and a tin antimony oxide thermal insulation layer 130; the aerogel layer 120 is disposed on one surface of the flame retardant plastic layer 110; the tin antimony oxide heat insulation layer 130 is disposed on the other surface of the flame retardant plastic layer 110. Wherein the aerogel layer 120 is configured to cover a surface of the fire rated wooden door to mount the fire patch 100 to the surface of the fire rated wooden door.
Specifically, the aerogel layer 120 is a light solid material having nano-scale pores and formed by stacking nano-scale particles, has a very high porosity and a very high specific surface area, and is excellent in chemical stability and non-flammability, and exhibits excellent light, light-transmitting, heat-insulating, heat-preserving, sound-insulating, fire-preventing, and impact-resisting properties. Wherein, the composition proportion of the air in the aerogel layer 120 accounts for more than 99.8%, and the aerogel layer is an excellent heat conduction insulating material, can almost block heat transfer brought by three heat transfer modes (heat conduction, heat convection and heat radiation), further realizes the heat insulation effect, and has certain fireproof performance.
As shown in fig. 2, the flame retardant plastic layer 110 has the advantages of high compression strength, high tensile strength, low water absorption, low moisture absorption, good dimensional stability, aging resistance, etc. while being fireproof, heat-insulating, sound-absorbing and noise-reducing. Through the flame-retardant plastic layer 110, the fire-retardant patch 100 has a good flame-retardant effect, and effectively delays the spread of fire. Since the fire prevention patch 100 is applied to the surface of the door frame 10 or the door leaf 20, the flame retardant plastic layer 110 may be transparent for the sake of product beauty, not blocking the original color of the door frame 10, to obtain a better appearance effect.
As shown in fig. 2, a tin antimony oxide thermal insulation layer 130 is disposed on a surface of the flame retardant plastic layer 110 away from the aerogel layer 120, and the tin antimony oxide thermal insulation layer 130 is a semiconductor thin film having a large forbidden bandwidth, a high carrier concentration, a high transmittance in a visible light region, and a high blocking rate in an infrared light region. The flame is composed of various combustion products, intermediates, high-temperature gas, hydrocarbon substances, and high-temperature solid particles mainly composed of inorganic substances. The thermal radiation of flame has the gas radiation of discrete spectrum and the solid radiation of continuous spectrum, and the flame radiation intensity, the wavelength distribution of different comburents are different, but on the whole, its 1 ~ 2 μm that corresponds the flame temperature has the biggest infrared radiation intensity. The tin antimony oxide heat insulation layer 130 can block flame radiation and has good heat insulation and fireproof performance, so that the fireproof performance of the fireproof patch 100 is improved.
It is understood that the tin antimony oxide thermal barrier layer 130 may be transparent for product aesthetics. The tin antimony oxide heat insulation layer 130 may be a coating layer, that is, the tin antimony oxide heat insulation coating layer is coated on the flame retardant plastic layer 110, so that the firmness between the flame retardant plastic layer 110 and the tin antimony oxide heat insulation layer 130 is improved, and the stability of the fire patch 100 is also improved. The tin antimony oxide thermal barrier layer 130 may be a nano tin antimony oxide thermal barrier layer 130.
The utility model discloses fire prevention paster 100 with fire prevention function that technical scheme provided is through setting up fire-retardant plastic layer 110 for fire prevention paster 100 has good effect of disturbing that hinders, delays wooden fire door effectively and meets naked light and take place the burning, has prevented stretching of conflagration to a certain extent, has strengthened the fire behavior of wooden fire door. An aerogel layer 120 is disposed on one surface of the fire-retardant plastic layer 110, and the aerogel layer 120 is used to cover the surface of the fire-proof wooden door, so as to mount the fire-proof patch 100 on the surface of the fire-proof wooden door. The aerogel layer 120 can effectively insulate heat and reduce the heat transfer, thereby providing a better insulation effect for the fire patch 100. The tin antimony oxide heat insulation layer 130 is arranged on the other surface of the flame retardant plastic layer 110, so that the heat insulation effect of the fire patch 100 is further improved for the infrared radiation of flame. The fireproof sheet 100 is applied to the whole wooden fireproof door or the joint of the door frame 10 and the door leaf 20, so that the fireproof performance of the joint of the door frame 10 and the door leaf 20 of the wooden fireproof door is enhanced, and the fireproof performance of the wooden fireproof door is improved.
The number of aerogel layers 120 may be one or more. To achieve better thermal insulation, in some embodiments, the aerogel layer 120 is multi-layered, as shown in fig. 2. Through the multiple aerogel layers 120, the good heat insulation function of the aerogel layers 120 is fully utilized, so that the fireproof patch 100 achieves a good heat insulation effect.
Further, as shown in fig. 2, in some embodiments, the number of layers of the aerogel layer 120 is 2 to 5.
The number of layers of this aerogel layer 120 also can be selected according to actual conditions to change multilayer aerogel layer 120's thickness, and then can change this fire prevention paster 100's thickness effectively, make fire prevention paster 100 highly match with the user's demand, the flexibility is strong. If the number of layers of the aerogel layer 120 is large, the fireproof performance of the fireproof patch 100 is enhanced, but the fireproof patch 100 is thick, so that the whole fireproof patch 100 is thick and not attractive; if the number of layers of aerogel layer 120 is small, the overall fire-blocking patch 100 is relatively thin and the fire-blocking properties of the fire-blocking patch 100 need to be enhanced. Preferably, the number of layers of the aerogel layer 120 is 3, so as to satisfy the fire-retardant property of the fire-retardant patch 100 and the appearance requirement of the fire-retardant patch 100.
In addition to the number of layers of the aerogel layer 120, the thickness of the aerogel layer 120 can also be adjusted. In some embodiments, as shown in fig. 2, each of the aerogel layers 120 has a thickness of 0.1 mm to 0.5 mm.
Further, in order to obtain better fire-retardant performance of the fire-retardant patch 100, match the needs of the user, and give consideration to the appearance of the fire-retardant patch 100, the thickness of each aerogel layer 120 is 0.1 mm to 0.5 mm. To achieve both the fire-blocking properties of the fire-blocking patch 100 and the appearance requirements of the fire-blocking patch 100, each aerogel layer 120 preferably has a thickness of 0.3 mm.
There are various ways of connecting the two aerogel layers 120, and in some embodiments, as shown in fig. 2, two adjacent aerogel layers 120 are connected by an adhesive layer 140.
In order to ensure that the thermal insulation effect of the aerogel layer 120 is achieved, the multiple aerogel layers 120 need to be uniformly layered, and the multiple aerogel layers 120 can be manufactured by a mechanical spraying method, i.e., a first adhesive layer 140 is sprayed, then a second adhesive layer 140 is sprayed, and then the aerogel layers 120 are sprayed, i.e., a multi-layer composite method is used to connect two adjacent aerogel layers 120 together. Specifically, in some embodiments, the material of the bonding layer 140 is polyurethane, or acrylate, or epoxy. It is understood that the adhesive layer 140 may be transparent.
Further, in some embodiments, the aerogel layer 120 is a silicon aerogel layer.
Because the silica aerogel is an ideal transparent heat insulation material, the nano network structure effectively limits the propagation of local thermal excitation, the solid heat conductivity is 2 to 3 orders of magnitude lower than that of a corresponding glassy material, the nano micro-pores inhibit the contribution of gas molecules to heat conduction, the sunlight can be effectively transmitted, the infrared heat radiation of the ambient temperature is prevented, the heat conductivity can be as low as 0.03 w/m.K, and the silica aerogel is a solid material with the lowest heat conductivity at present. Therefore, the aerogel layer 120 is a silicon aerogel layer, thereby effectively blocking infrared heat radiation, and has good light transmittance without affecting the appearance of the door frame 10.
Further, in some embodiments, the thickness of the flame retardant plastic layer 110 is 1.0 mm to 3.0 mm.
The flame-retardant plastic layer 110 is arranged between the aerogel layer 120 and the tin antimony oxide heat insulation layer 130, and the thickness of the flame-retardant plastic layer 110 is 1.0 mm to 3.0 mm, so that the hardness of the fireproof patch 100 can be adjusted, the problem that the whole hardness of the fireproof patch 100 is insufficient due to the thickness limitation of the fireproof patch 100 is avoided, and the fireproof patch 100 can be applied to occasions with higher hardness requirements. Moreover, with the change of the thickness of the flame retardant plastic layer 110, the hardness of the fire retardant patch 100 can be flexibly adjusted to meet the user requirements.
Note that, in order to achieve both the rigidity and the thickness of the fire patch 100, the thickness of the flame retardant plastic layer 110 may be 2.0 mm. The flame retardant plastic layer 110 may be a highly transparent material to improve the transparency of the fire patch 100 as a whole.
Further, in some embodiments, the material of the flame retardant plastic layer 110 is polyvinyl chloride or polystyrene.
The flame-retardant plastic layer 110 made of polyvinyl chloride or polystyrene has high flame retardancy and strong impact resistance, and can effectively delay the spread of fire, and the flame-retardant plastic layer 110 made of polystyrene can further enhance the fireproof performance of the fireproof patch 100 and improve the fireproof limit of the fireproof patch 100.
Further, in some embodiments, the flame retardant plastic layer 110 is rated V-0 for flame retardancy.
The flame-retardant rating, i.e. the property of a substance or of a material treated to significantly delay the spread of flame, is classified according to this rating system. The flame retardant grades comprise HB, V-2, V-1 and V-0, and the flame retardant grades of HB, V-2, V-1 and V-0 are gradually increased. Flame retardant rating HB is the lowest flame retardant rating in the UL94 standard, requiring a burn rate of less than 40 millimeters per minute for samples 3 to 13 millimeters thick; for samples less than 3 mm thick, the burn rate is less than 70 mm per minute; or extinguished before the 100 mm mark. A flame rating of V-2 requires that after two 10 second burn tests on the sample, the flame is extinguished within 60 seconds and any combustibles can fall off. A flame rating of V-1 requires that after two 10 second burn tests on the sample, the flame is extinguished within 60 seconds and no combustibles can fall off. A flame rating of V-0 requires that after two 10 second burn tests on the sample, the flame is extinguished within 30 seconds and no combustibles can fall off. The flame retardant plastic layer 110 may have a flame retardant rating of V-0, i.e., two 10 second burn test flames can extinguish the combustibles within 30 seconds.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
