The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The fire integrity of 1.00 hour as used herein means that, according to the building design fire code GB50016-2014, a residential building with a building height greater than 54m should have one room per household which meets the following regulations: 1. the openable outer window is arranged close to the outer wall; 2. the fire endurance of the inner and outer walls should not be lower than 1.00 hours, the door of the room should be a class B fire door, and the fire integrity of the outer window should not be lower than 1.00 hours.
It should be noted that, the fire-resistant integrity of the door and window described herein refers to the ability of the building door and window to prevent flame and smoke from penetrating the fire-back surface to generate flame for a certain period of time when a fire is exposed to a certain fire-facing surface under standard fire-resistant experimental conditions.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a profile according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a profile including a surface layer structure according to an embodiment of the present invention.
The invention provides a section bar 100 which can meet the condition that the fire resistance integrity is not less than 1.00 hour, wherein the section bar 100 comprises a section bar body 10 and a core material 20, a cavity 11 is formed in the section bar body 10, the core material 20 is filled in the cavity 11, the core material 20 can be carbonized at the temperature of more than 300 ℃, and the carbon residue rate of the core material 20 is 50-80%.
Further, the core material 20 includes a first core material 21 and a second core material 22, and the density of the first core material 21 is greater than that of the second core material 22. The first core 22 supports the inner wall of the cavity 11, and the filling ratio of the first core 21 is 35% to 50%, and the filling ratio of the second core 22 is 40% to 50%. If the filling ratio of the first core material 21 is less than 35% or the filling ratio of the second core material 22 is less than 40%, the fire resistance integrity of 1.00 hour cannot be achieved, and within this ratio range, the core material 20 can achieve not only the fire resistance integrity of 1.00 hour but also light weight and low cost.
The core material 20 of the present invention has good flame retardancy, the core material 20 can be partially carbonized at a temperature of more than 300 ℃ without burning, and the core material 20 can be fully carbonized and resistant to high temperature burning without open flame on the outside. The core material 20 has the characteristics of light weight, fire resistance, no combustion in open fire, no smoke, no toxicity, no dripping, no shrinkage in a low-temperature environment and no embrittlement, and is preferably made of, but not limited to, phenolic resin and benzoxazine.
Further, first core 21 supports the inner wall of cavity 11, can guarantee the structural stability of section bar body 10 when meeting fire burning, and second core 22 is filled in cavity 11, can play protection and cushioning effect to first core 21 when meeting fire to strengthen the support nature of first core 21 to section bar body 10, in order to promote section bar 100 overall structure's integrality, make section bar 100 be difficult for collapsing when meeting fire burning, and then improve section bar 100's fire resistance.
In addition, the profile 100 of the invention has low heat conductivity coefficient and good heat insulation effect, thereby having better heat preservation and energy saving effects.
Further, the density of the first core material 21 is 1700kg/m3～1850kg/m3。
The density of the second core material 22 was 60kg/m3～80kg/m3The core material 20 is light in weight, high in specific strength and certain in mechanical strength due to the existence of the bubbles which are uniformly distributed in the core material, and can absorb impact load. The density is related to the fire resistance, with higher densities giving better and lower densities giving poorer fire resistance. In addition, the density of the second core 22 also affects its weight and cost, so the density of the second core 22 is 60kg/m in case of meeting the fire integrity for 1.00 hour3～80kg/m3Is most preferred. Preferably, the density of the second core material 22 is 65kg/m3～75kg/m3. The material of the second core material 22 is preferably, but not limited to, a phenolic foam material and a benzoxazine foam material, and after foaming and curing, the material is basically free of harmful substances.

It is understood that the specific shape of the first core material 21 is not limited in the present invention without affecting the fire resistance of the first core material 21, and in other embodiments, the longitudinal section of the first core material 21 may have other regular or irregular shapes.
Furthermore, the number of the cavities 11 is more than one, the cavities comprise a first cavity 111 and a second cavity 112, the first cavity 111 is arranged to be relatively close to the back fire surface, the second cavity 112 is arranged to be relatively close to the fire surface, the volume ratio of the first cavity 111 to the second cavity 112 is (3-5): 5, and the core material 20 is at least partially filled in the second cavity 112. In one preferred embodiment, the core material 20 is entirely filled in the second cavity 112 and is not filled in the first cavity 111, and in another preferred embodiment, the core material 20 is partially filled in the second cavity 112 and is partially filled in the first cavity 111.
It should be understood that the number of the cavities 11 may also be set to only 1, and may also be set to more than 3, and the number and the presentation form of the cavities 11 are not limited by the present invention.
It should be noted that the second cavity 112, which is configured to be relatively close to the fire-facing surface, has a relatively large volume, and thus a large volume fraction of the core material 20 may be disposed in the second cavity 112 to provide a fire-facing surface with a large flame-retardant duration.
Preferably, the wall thickness of the profile body 10 is greater than or equal to 3mm, so that the profile body has better burning resistance and support property when being subjected to fire charring. It can be understood that, when the profile body 10 is applied to different door and window products, the upper limit of the wall thickness of the profile body 10 is not limited, and can be set according to actual requirements.
Further, the material of the profile body 10 includes a fiber material and a polymer material, and the mass percentage of the fiber material in the profile body 10 is 60% to 85%.
