Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rock wool board, in particular to a fire-resistant and flame-retardant rock wool board for green building facilities. BACKGROUND

[0002] Rock wool board is a porous inorganic fireproof board made of natural inorganic minerals such as basalt and diabase as the main raw material, through high-temperature melting, fiberization treatment, adding appropriate inorganic binder, and then through pressing, curing, cutting and other processes. As a class A non-combustible material, rock wool board has become an indispensable core material in the fields of building and industry due to its excellent fire-resistant and flame-retardant, thermal insulation properties. In the field of construction, rock wool board is widely used in external wall insulation, internal wall partition, suspended ceiling fireproofing, steel structure fireproofing and other scenes. With the popularization of green building concept and the improvement of building energy-saving standards, rock wool board, with its inorganic, environmentally friendly, no VOC release and low thermal conductivity, meets the multiple demands of modern buildings for energy saving, environmental protection and safety, and is an ideal material for achieving building envelope thermal insulation and improving building fire rating. Its porous fiber structure can effectively block heat conduction and air convection, significantly reducing building energy consumption and helping buildings to achieve green building evaluation standards. The existing rock wool board, such as the one disclosed in CN219219418U, uses multiple layers of flame-retardant layers to protect the rock wool board, with good flame-retardant performance, high structural strength, good sound insulation effect and wide application range. However, the above-mentioned prior art cannot avoid temperature transverse penetration, because the rock wool board has a porous structure, although the pore size is small, but when the temperature is transmitted, there is no gas conduction path, which will slowly penetrate the porous rock wool board, and then the rock wool board will be transversely penetrated by the temperature, resulting in the weakening of its fireproofing and thermal insulation performance. In addition, the above-mentioned prior art cannot guarantee the tightness between the layers, which will cause the flame and high-temperature smoke to flow in the gap, thereby greatly reducing its fireproofing performance. When the existing rock wool board is spliced, the outermost rock wool board inevitably needs to be cut, and due to the loose structure of the rock wool board, cutting will easily cause the rock wool board to crack locally, which is not conducive to the stability of the overall structure composed of several rock wool boards. Therefore, there is a need for a fire-resistant and flame-retardant rock wool board for green building facilities to solve the above problems. SUMMARY

[0003] The present application relates to the technical field of rock wool board, in particular to a fire-resistant and flame-retardant rock wool board for green building facilities.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A fire-resistant and flame-retardant rock wool board for green building facilities includes a rock wool layer and a fire-resistant and wear-resistant surface layer and a decorative fireproof layer respectively disposed on its front and back sides. The front and back sides of the rock wool layer are uniformly provided with grooves, and the fire-resistant and wear-resistant surface layer and the decorative fireproof layer are respectively connected to the grooves on the front and back sides of the rock wool layer by a tenon and mortise splicing mechanism. The tenon and mortise splicing mechanism includes an overlapping block disposed in each groove, and two overlapping blocks are disposed in each groove. The outer sides of the rock wool layer, the fire-resistant and wear-resistant surface layer and the decorative fireproof layer are connected by a splicing and pressing mechanism, and the splicing and pressing mechanism includes a slot disposed on the outer side of the rock wool layer.

[0005] Preferably, the tenon and mortise splicing mechanism further includes embedded blocks on the sides of the fireproof and wear-resistant surface layer and the decorative fireproof layer facing the rock wool layer, and snap-fit ​​blocks are also provided on the sides of the fireproof and wear-resistant surface layer and the decorative fireproof layer facing the rock wool layer.

[0006] Preferably, the snap-fit ​​block and the embedding block have equal widths and are correspondingly arranged, and the width of the snap-fit ​​block and the embedding block is smaller than the width of the groove on the rock wool layer.

[0007] Preferably, the tenon and mortise splicing mechanism further includes a locking groove provided on the side of each groove, and a locking block provided on each of the embedded blocks, wherein the size of the locking block and the locking groove are matched.

[0008] Preferably, the overlapping block and the rock wool layer form a right-angle overlapping groove, and the right-angle overlapping groove matches the lower end of the embedded block to ensure the tightness of the connection between the fireproof and wear-resistant surface layer and the decorative fireproof layer and the rock wool layer.

[0009] Preferably, the splicing and pressurizing mechanism further includes a fireproof gypsum upper frame plate and a fireproof gypsum lower frame plate respectively provided on the upper and lower sides of the rock wool layer, and the lower surface of the fireproof gypsum upper frame plate and the upper surface of the fireproof gypsum lower frame plate are provided with locking strips. The locking strips are engaged and connected in the locking grooves provided on the outer side of the rock wool layer, and the two ends of the fireproof gypsum upper frame plate are respectively complementary and connected to the two ends of the fireproof gypsum lower frame plate.

[0010] Preferably, the splicing and pressurizing mechanism further includes a longitudinal embedding groove on the upper surface of the fireproof gypsum upper frame plate, a longitudinal embedding strip corresponding to the longitudinal embedding groove on the lower surface of the fireproof gypsum lower frame plate, and transverse embedding strips and transverse embedding grooves respectively on the left and right sides of the fireproof gypsum upper frame plate and the fireproof gypsum lower frame plate, with the transverse embedding strips and transverse embedding grooves matching in size.

[0011] Preferably, the splicing and pressurizing mechanism further includes pins on both the lower surface of the upper fireproof gypsum frame and the upper surface of the lower fireproof gypsum frame, and the difference in lateral length between the groove and the embedded block matches the lateral width of the pin. The upper surface of the upper fireproof gypsum frame and the lower surface of the lower fireproof gypsum frame are both penetrated by corresponding pins through heat-conducting holes, and the heat-conducting holes on the opposite pins are connected by a butt flat tube. The butt flat tube is made of an intumescent flame-retardant resin composite material.

[0012] Preferably, the splicing and pressurizing mechanism further includes transverse pressurizing grooves on both sides of the fireproof and wear-resistant surface layer and the decorative fireproof layer, and transverse pressurizing strips corresponding to the transverse pressurizing grooves are provided on the vertical portions of the fireproof gypsum upper frame plate and the fireproof gypsum lower frame plate.

[0013] Preferably, the splicing and pressurizing mechanism further includes longitudinal pressurizing grooves provided on both the upper and lower surfaces of the fireproof and wear-resistant surface layer and the decorative fireproof layer, and longitudinal pressurizing blocks corresponding to the longitudinal pressurizing grooves are provided on the lower surface of the fireproof gypsum upper frame plate and the upper surface of the fireproof gypsum lower frame plate.

[0014] Compared with existing technologies, the beneficial effects of this invention are: the fire-resistant and flame-retardant rock wool board used in this green building facility facilitates longitudinal heat transfer and prevents lateral penetration, thereby increasing its thermal insulation performance. Furthermore, the mortise and tenon joint mechanism and the joint pressing mechanism ensure the tightness of the connection between the fire-resistant and wear-resistant surface layer, the decorative fireproof layer, and the rock wool layer, thus reducing the gaps between them and improving fire resistance. It also avoids the use of formaldehyde-containing adhesives, conforming to the concept of green environmental protection. Installing fire-resistant gypsum upper and lower frame boards on the outside of the fire-resistant and wear-resistant surface layer, the decorative fireproof layer, and the rock wool layer further enhances its overall compactness and prevents localized deformation. 1. The mortise and tenon splicing mechanism allows the two sides of the rock wool layer to be stably connected to the fireproof and wear-resistant surface layer and the decorative fireproof layer, respectively. This avoids the harm caused by the use of formaldehyde-containing glue in the past and conforms to the concept of green environmental protection. In addition, the contact and compression connection of the embedded blocks and overlapping blocks on the mortise and tenon splicing mechanism allows the two sides of the rock wool layer to be compressed against the fireproof and wear-resistant surface layer and the decorative fireproof layer, respectively, thereby ensuring the tightness of the overall structure of the three. By improving the tightness between the three, the gap at the connection point can be reduced, thereby improving the fire resistance performance. 2. When several rock wool boards are spliced ​​together, the compression between adjacent rock wool boards can cause the transverse pressure grooves and transverse pressure strips, as well as the longitudinal pressure grooves and longitudinal pressure blocks on the splicing pressure mechanism, to compress each other. This helps to improve the tightness of the connection between the two sides of the rock wool layer and the fireproof and wear-resistant surface layer and the decorative fireproof layer, thereby helping to further reduce the gap at the connection of the three and further improve the fireproof performance. 3. The pins on the upper and lower fireproof gypsum frame panels prevent the locking blocks from being pulled out of the locking grooves. The heat conduction holes on the pins facilitate longitudinal temperature transfer, thereby reducing the degree of lateral temperature penetration and helping to increase the thermal insulation performance of the rock wool board. 4. The fireproof gypsum upper frame and lower frame can easily package the rock wool layer, fireproof and wear-resistant surface layer and decorative fireproof layer into a whole, which helps to improve the overall compactness of the three components and thus ensures that local deformation does not easily occur when heated. 5. Connecting the opposing pins with the butt flat tubes facilitates support during rock wool board cutting, preventing localized cracking and ensuring structural stability. Furthermore, the butt flat tubes, made of expandable flame-retardant resin composite material, expand upon heating, resulting in a tighter connection between the pins and enhancing the rock wool board's strength after heating.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-15 The present invention provides the following technical solution: Example 1: To address the issue that traditional rock wool boards use adhesives to connect the functional layers, leading to the release of toxic and harmful substances that contradict green and environmentally friendly principles, the following technical solution is provided: a fire-resistant and flame-retardant rock wool board for green building facilities, comprising a rock wool layer 12 and a fire-resistant and wear-resistant surface layer 1 and a decorative fireproof layer 14 respectively disposed on its front and back sides. Grooves are evenly provided on both the front and back sides of the rock wool layer 12, and the fire-resistant and wear-resistant surface layer 1 and the decorative fireproof layer 14 are connected to the grooves on the front and back sides of the rock wool layer 12 respectively through a tenon and mortise splicing mechanism. The tenon and mortise splicing mechanism includes an overlapping block 21 disposed in each groove, and two overlapping blocks 21 are disposed in each groove.

[0019] The mortise and tenon joint mechanism also includes embedded blocks 16 on the sides of the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 facing the rock wool layer 12, and snap-fit ​​blocks 15 on the sides of the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 facing the rock wool layer 12. The snap-fit ​​blocks 15 and embedded blocks 16 are of equal width and are correspondingly arranged. The width of the snap-fit ​​blocks 15 and embedded blocks 16 is smaller than the width of the groove on the rock wool layer 12. The mortise and tenon joint mechanism also includes a snap-fit ​​groove 22 on the side of each groove, and a snap-fit ​​block 17 on each embedded block 16. The snap-fit ​​blocks 17 and snap-fit ​​grooves 22 are of the same size. The overlapping block 21 and the rock wool layer 12 form a right-angle overlapping groove, and the right-angle overlapping groove matches the lower end of the embedded block 16 to ensure the tightness of the connection between the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 and the rock wool layer 12.

[0020] according to Figure 1 , Figure 6 , Figures 9-12 The fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 are fitted with the snap-fit ​​blocks 15 and the embedded blocks 16 in the grooves on the side of the rock wool layer 12, and the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 are slid longitudinally until the embedded block 16 is connected to the corresponding overlapping block 21. At this time, because the right-angle overlapping groove formed by the overlapping block 21 and the rock wool layer 12 is pressed against the lower end of the embedded block 16, the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 can be in close contact with the two sides of the rock wool layer 12 respectively. Then, the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 are slid laterally, so that the locking block 17 connected to the embedded block 16 is locked into the corresponding locking groove 22. At this time, the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 will complete the initial connection with the rock wool layer 12. Finally, by using the pins 8 on the splicing pressure mechanism, the gap between the groove and the embedded block 16 is filled, thereby ensuring that the locking block 17 and the locking groove 22 are stably connected. The above process does not require the use of formaldehyde-containing adhesives, thus avoiding the release of toxic and harmful substances, which is in line with the concept of green environmental protection.

[0021] Example 2: To address the problem that previous rock wool boards did not have a structure for longitudinal temperature transfer, which easily led to lateral temperature penetration into the rock wool board and made it impossible to ensure the tightness of the connection between the functional layers of the rock wool board, thus reducing its fire resistance, the following technical solution is provided: Specifically, the outer sides of the rock wool layer 12, the fireproof and wear-resistant surface layer 1, and the decorative fireproof layer 14 are connected by a splicing and pressurizing mechanism, and the splicing and pressurizing mechanism includes a slot 13 set on the outer side of the rock wool layer 12.

[0022] The splicing and pressurizing mechanism also includes a fireproof gypsum upper frame plate 2 and a fireproof gypsum lower frame plate 3 respectively provided on the upper and lower sides of the rock wool layer 12. The lower surface of the fireproof gypsum upper frame plate 2 and the upper surface of the fireproof gypsum lower frame plate 3 are each provided with a retaining strip 10, which engages with a retaining groove 13 provided on the outer side of the rock wool layer 12. The two ends of the fireproof gypsum upper frame plate 2 and the two ends of the fireproof gypsum lower frame plate 3 are respectively complementary. The splicing and pressurizing mechanism also includes a longitudinal embedding groove 5 provided on the upper surface of the fireproof gypsum upper frame plate 2, and a longitudinal embedding strip 18 corresponding to the longitudinal embedding groove 5 provided on the lower surface of the fireproof gypsum lower frame plate 3. Horizontal embedding strips 11 and horizontal embedding grooves 6 are respectively provided on the left and right sides of the fireproof gypsum upper frame plate 2 and the fireproof gypsum lower frame plate 3. The sizes of the horizontal embedding strips 11 and the horizontal embedding grooves 6 match. The splicing and pressurizing mechanism also includes... The pin 8 has a groove and the difference in lateral length between the groove and the embedded block 16 that matches the lateral width of the pin 8. The upper surface of the fireproof gypsum upper frame plate 2 and the lower surface of the fireproof gypsum lower frame plate 3 are both penetrated by the corresponding pin 8 through the heat conduction hole 4. The heat conduction holes 4 on the opposite pin 8 are connected by the butt flat tube 23. The butt flat tube 23 is made of intumescent flame-retardant resin composite material. The splicing and pressurizing mechanism also includes a transverse pressurizing groove 20 on both sides of the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14. The vertical parts of the fireproof gypsum upper frame plate 2 and the fireproof gypsum lower frame plate 3 are provided with transverse pressurizing strips 9 corresponding to the transverse pressurizing grooves 20. The splicing and pressurizing mechanism also includes a longitudinal pressurizing groove 19 on both the upper and lower surfaces of the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14. The lower surface of the fireproof gypsum upper frame plate 2 and the upper surface of the fireproof gypsum lower frame plate 3 are provided with longitudinal pressurizing blocks 7 corresponding to the longitudinal pressurizing grooves 19.

[0023] according to Figures 3-6 as well as Figures 13-15 After the fireproof and wear-resistant surface layer 1 and the decorative fireproof layer 14 are respectively connected to the rock wool layer 12, the fireproof gypsum upper frame plate 2 and the fireproof gypsum lower frame plate 3 will be connected to the rock wool layer 12 through the clip 10. Then, the two ends of the fireproof gypsum upper frame board 2 are respectively connected to the two ends of the fireproof gypsum lower frame board 3. At this time, the whole consisting of the fireproof and wear-resistant surface layer 1, the decorative fireproof layer 14 and the rock wool layer 12 will be wrapped by the whole consisting of the fireproof gypsum upper frame board 2 and the fireproof gypsum lower frame board 3, thereby improving its integrity. While the fireproof gypsum upper frame plate 2 and the fireproof gypsum lower frame plate 3 wrap the fireproof and wear-resistant surface layer 1, the decorative fireproof layer 14 and the rock wool layer 12, the longitudinal pressure block 7 will be connected to the longitudinal pressure groove 19, and the transverse pressure groove 20 will be connected to the transverse pressure strip 9, thereby further improving the tightness of the connection between the fireproof and wear-resistant surface layer 1, the decorative fireproof layer 14 and the rock wool layer 12. When splicing several rock wool boards, the transverse embedding groove 6 and the corresponding transverse embedding strip 11 are engaged, and the longitudinal embedding groove 5 and the corresponding longitudinal embedding strip 18 are engaged. During the engagement of the transverse embedding groove 6 and the corresponding transverse embedding strip 11, and the engagement of the longitudinal embedding groove 5 and the corresponding longitudinal embedding strip 18, the longitudinal pressure block 7 and the transverse pressure strip 9 are squeezed and will have the tendency to move into the longitudinal pressure groove 19 and the transverse pressure groove 20 respectively, thereby further improving the tightness between the fireproof and wear-resistant surface layer 1, the decorative fireproof layer 14 and the rock wool layer 12. By improving the tightness between the fireproof and wear-resistant surface layer 1, the decorative fireproof layer 14 and the rock wool layer 12, the gaps between the three can be reduced, thereby preventing flames and high-temperature smoke from flowing through the gaps and thus avoiding a reduction in the fire resistance of the rock wool board. In addition, pins 8 for filling the gaps between the groove and the embedded block 16 are provided on the lower surfaces of the upper and lower fireproof gypsum frame 2 and the lower fireproof gypsum frame 3, respectively. Heat conduction holes 4 are provided between the upper and lower fireproof gypsum frame 2 and the corresponding pins 8, which facilitates longitudinal temperature transfer and reduces or even avoids transverse temperature transfer that could cause the rock wool board to be penetrated laterally. This ensures the thermal insulation performance of the rock wool board and prevents its fire resistance from being weakened.
