Description

Technical Field

[0001] This utility model relates to the field of polypropylene sheet technology, and more specifically to a fireproof polypropylene sheet. Background Technology

[0002] Polypropylene is a polymer formed by the addition polymerization of propylene. It has a service temperature range of -30 to 140℃ and is resistant to corrosion from acids, alkalis, salt solutions, and various organic solvents below 80℃. It also possesses high impact resistance and strong mechanical properties. Therefore, polypropylene sheets have high impact resistance and can be used in the construction industry as lightweight partition boards, decorative panels, roofing panels, etc., and can also be used for the protection of building elevators and floors before acceptance. For example, a novel polypropylene sheet with prior art publication number CN215521510U includes a body composed of a first sheet and a second sheet, which are connected by a connecting mechanism.

[0003] However, the existing technology described above still has the following problems in use: traditional polypropylene sheets have low high-temperature resistance, and when exposed to oxygen in a fire, they are easily burned and destroyed, resulting in low fire resistance. Therefore, this invention provides a fire-resistant polypropylene sheet. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a fireproof polypropylene sheet. By covering the outside of the polypropylene substrate with a fireproof mesh cloth, the ceramic fibers and glass fibers in the fireproof mesh cloth are both heat-resistant and can block oxygen to suppress flames, thus playing a fireproof role on the outside of the polypropylene substrate. Furthermore, by applying a fireproof coating to cover the entire surface of the fireproof mesh cloth, the fire resistance of the polypropylene substrate can be further improved, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof polypropylene sheet, comprising a sheet body, the sheet body comprising a polypropylene substrate, a first fireproof layer fixedly sleeved on the outer wall of the polypropylene substrate, a second fireproof layer provided on the outer surface of the first fireproof layer, a reinforcing component provided on the outer wall of the second fireproof layer, the first fireproof layer comprising a fireproof mesh cloth, the fireproof mesh cloth being woven from multiple transverse fibers and multiple longitudinal fibers, the transverse fibers being ceramic fibers, and the longitudinal fibers being glass fibers.

[0006] In a preferred embodiment, the second fireproof layer includes a fireproof coating applied to the surface of the fireproof mesh fabric, which solidifies to form a fireproof coating that provides fire protection.

[0007] In a preferred embodiment, multiple uniformly distributed micropores are formed between multiple transverse fibers and multiple longitudinal fibers. The fire-retardant coating is disposed within the micropores, which can improve its adhesion to the fire-retardant mesh fabric and prevent oxygen from contacting the polypropylene substrate through the micropores.

[0008] In a preferred embodiment, the reinforcement component includes first reinforcement frames disposed on both sides of the second fireproof layer, and two second reinforcement frames disposed between the two first reinforcement frames. The two second reinforcement frames are respectively disposed at the front end and the rear end of the second fireproof layer. By using the first reinforcement frames and the second reinforcement frames in combination, the connection between the first fireproof layer and the polypropylene substrate can be improved.

[0009] In a preferred embodiment, the first reinforcing frame and the second reinforcing frame, as well as the first reinforcing frame and the polypropylene substrate, are detachably fixed together by multiple fastening bolts, which facilitates the quick installation of the first and second reinforcing frames, thereby improving installation efficiency and making it easy to disassemble the first and second reinforcing frames for recycling.

[0010] In a preferred embodiment, the outer wall surfaces of both first reinforcing frames are provided with the same number of fixing holes as the fastening bolts, which are used to accommodate the fastening bolts to prevent them from protruding outwards and to avoid the fastening bolts affecting the subsequent installation of the plate.

[0011] In a preferred embodiment, two positioning grooves are machined on both sides of the two second reinforcing frames, and positioning blocks that are adapted to the positioning grooves are fixed on the side of the two first reinforcing frames near the second reinforcing frames. The positioning blocks are inserted into the positioning grooves, and multiple positioning blocks and multiple fastening bolts are distributed at intervals to improve the connection between the first reinforcing frames and the second reinforcing frames.

[0012] In a preferred embodiment, the first reinforcing frame, the second reinforcing frame, and the fastening bolts are all made of stainless steel.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model provides a fireproof mesh cloth on the outside of a polypropylene substrate.

Furthermore, fireproof coating is applied to cover the entire surface of the fireproof mesh cloth, thereby further improving the fire resistance of the polypropylene substrate.

[0015] 2. The fireproof mesh is reinforced on the outside by two first reinforcing frames and two second reinforcing frames, which can improve the connection between the fireproof mesh and the polypropylene substrate. In addition, the first and second reinforcing frames can protect the edges and corners of the fireproof mesh and can also be used as connectors when splicing panels. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Refer to the instruction manual appendix Figures 1-6This utility model provides a fireproof polypropylene sheet, including a sheet body 1, the sheet body 1 including a polypropylene substrate 11, a first fireproof layer 12 fixedly sleeved on the outer wall of the polypropylene substrate 11, a second fireproof layer 13 provided on the outer surface of the first fireproof layer 12, a reinforcing component 2 provided on the outer wall of the second fireproof layer 13, the first fireproof layer 12 including a fireproof mesh fabric 121, the fireproof mesh fabric 121 being woven from multiple transverse fiber filaments 1211 and multiple longitudinal fiber filaments 1212, the transverse fiber filaments 1211 being ceramic fiber, the longitudinal fiber filaments 1212 being glass fiber, and multiple uniformly distributed micropores 1213 forming between the multiple transverse fiber filaments 1211 and the multiple longitudinal fiber filaments 1212.

[0027] The second fireproof layer 13 includes a fireproof coating applied to the surface of the fireproof mesh 121. The fireproof coating solidifies to form a fireproof coating layer, which plays a fireproof role. Furthermore, the fireproof coating is disposed in the micropores 1213, which can improve its adhesion to the fireproof mesh 121.

[0028] In practical applications, a fireproof mesh fabric 121 is applied to the outside of the polypropylene substrate 11. The ceramic fibers in the fireproof mesh fabric 121 have excellent high-temperature resistance, and they can form a relatively dense covering layer on the surface of the polypropylene substrate 11. In the event of a fire, this covering layer can block oxygen from contacting the polypropylene substrate 11, thereby inhibiting the combustion reaction of the polypropylene substrate 11 and improving its fire resistance. Simultaneously, the glass fiber also possesses high-temperature resistance and forms a protective layer that blocks oxygen contact; furthermore, the glass fiber itself is non-combustible. It can suppress flames to a certain extent, thereby improving the fire resistance of the fireproof mesh 121. Fireproof coatings (such as epoxy resin fireproof coatings, whose epoxy groups in molecular structure have strong reactivity and can react chemically with the polar groups on the surface of polypropylene sheets to form strong chemical bonds, thus giving the fireproof coating excellent adhesion to the surface of polypropylene sheets) are applied to the surface of the fireproof mesh 121. The fireproof coating fills the micropores 1213 on the surface of the fireproof mesh 121, thereby further improving the fire resistance of the fireproof mesh 121. Example 2

[0029] Refer to the instruction manual appendix Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The reinforcement component 2 includes a first reinforcement frame 21 disposed on both sides of the second fireproof layer 13, and two second reinforcement frames 22 disposed between the two first reinforcement frames 21. The two second reinforcement frames 22 are respectively disposed at the front end and the rear end of the second fireproof layer 13 to improve the stability of the first fireproof layer 12. The first reinforcement frame 21 and the second reinforcement frame 22, as well as the first reinforcement frame 21 and the polypropylene substrate 11, are detachably fixed together by a plurality of fastening bolts 23.

[0030] Furthermore, the first reinforcing frame 21, the second reinforcing frame 22, and the fastening bolts 23 are all made of stainless steel. Stainless steel has a high melting point and good thermal stability. Therefore, in the event of a fire, the first reinforcing frame 21, the second reinforcing frame 22, and the fastening bolts 23 will not burn or melt rapidly and can maintain a certain strength and structural integrity under the action of fire.

[0031] By setting a reinforcing component 2 on the outside of the polypropylene substrate, the reinforcing component 2 is spliced ​​together from two first reinforcing frames 21 and two second reinforcing frames 22, which can improve the connection between the fireproof mesh 121 and the polypropylene substrate. Furthermore, the first reinforcing frames 21 and the second reinforcing frames 22 can not only protect the edges and corners of the fireproof mesh 121, but also be used as connectors when splicing the panels 1.

[0032] Furthermore, the same number of fixing holes 24 as the fastening bolts 23 are provided on the outer wall surface of both first reinforcing frames 21 to accommodate the fastening bolts 23 and prevent them from protruding outward, thus avoiding the protruding fastening bolts 23 from affecting the installation and splicing of the plate body 1.

[0033] To improve the assembly efficiency between the first reinforcing frame 21 and the second reinforcing frame 22, two vertically distributed positioning grooves 3 are machined on both sides of the two second reinforcing frames 22. Positioning blocks 4 that are adapted to the positioning grooves 3 are fixedly provided on the side of the two first reinforcing frames 21 near the second reinforcing frame 22. The positioning blocks 4 are inserted into the positioning grooves 3, and multiple positioning blocks 4 are distributed with multiple fastening bolts 23 at intervals. By cooperating with the positioning grooves 3, the assembly efficiency can be improved, and the connection between the first reinforcing frame 21 and the second reinforcing frame 22 can be strengthened.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
