Description

Technical Field

[0001] The utility model relates to the technical field of PVC boards, in particular to a flame-retardant PVC board. Background Art

[0002] PVC sheets can be used as building sheets. They are lightweight, heat-insulating, thermally insulating, moisture-proof, flame-retardant, and easy to construct. They come in a variety of specifications, colors, and patterns and are highly decorative. They can be used for the decoration of interior walls and ceilings of living rooms, as well as in distribution rooms, instrument rooms, laboratories, warehouses, gymnasiums, fitness centers, and as flooring materials for vehicles and ships. They are one of the most widely used decorative materials among plastic materials.

[0003] The flame-retardant PVC boards currently on the market can be enhanced by adding magnesium hydroxide flame retardant before thermoplastic molding to improve their flame retardancy and effectively reduce the emission of toxic and harmful gases. However, when an open flame comes into contact with the surface of the board in the installation area, it can only play a non-combustible role and cannot slow down or suppress the open flame. The fire safety performance of PVC boards during installation is relatively general, and the market competitiveness of similar products needs to be strengthened. Utility Model Content

[0004] The purpose of the utility model is to provide a flame-retardant PVC board to solve the problem proposed in the above-mentioned background technology that after an open flame is generated in the installation area and contacts with the surface, the PVC board can only play a non-combustible effect but cannot slow down or suppress the open flame. The fire safety performance of the PVC board during installation and use is relatively general, and the market competitiveness of equivalent products needs to be strengthened.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flame-retardant PVC board, comprising a substrate, a plurality of grooves are provided on the lower surface of the substrate, a groove block is provided at the inner top of the groove, insertion holes are provided on both sides of the inner top of the groove, a plug rod is inserted into the inside of the plug rod, the plug rod is fixedly connected to the contact surface of the groove block, a fire extinguishing ball is clamped at the lower part of the inner part of the groove block, a lead wire is provided at the lower part of the fire extinguishing ball, a baffle is attached to the lower surface of the substrate, a plurality of through holes are evenly provided on the upper surface of the baffle, a plug is provided inside the through hole, vertical pipes are inserted into the four corners of the lower surface of the baffle, bolts are provided inside the vertical pipes, and a part of the bolts can pass through the baffle and the substrate in sequence through the vertical pipes.

[0006] Preferably, the through hole is a tapered hole.

[0007] Preferably, the top end of the outer wall of the riser is a conical structure.

[0008] Compared with the prior art, the beneficial effects of the utility model are: the flame retardant PVC board has the following advantages over the traditional technology:

[0009] Through the coordination among the base plate, grooves, slot blocks, sockets, plugs, fire extinguishing balls, leads, baffles, through holes, plugs, risers and bolts, when an open flame is generated inside the plate installation space and approaches the baffle surface, the plug inside the through hole will melt and fall off due to the heat, and the through hole will be in an open state. Further open flame will ignite the fuse, and the fire extinguisher driving medium will be activated, causing the shell to expand and rupture rapidly. The internal dry powder fire extinguishing agent will be quickly sprayed through the through hole and quickly diffused, which can suppress or slow down the spread of the open flame generated in the installation space, improve the fire safety performance during use and installation, and enhance the market competitiveness of equivalent products.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3The utility model provides a technical solution: a flame-retardant PVC board, including a substrate 1, the substrate 1 and the baffle 8 are both made of PVC material, and magnesium hydroxide flame retardant is added before thermoplastic molding to improve the flame retardant performance of the substrate 1 and the baffle 8, and can also effectively reduce the emission of toxic and harmful gases generated after encountering fire. A plurality of grooves 2 are provided on the lower surface of the substrate 1, and a groove block 3 is provided at the top of the inner part of the groove 2. Plug holes 4 are provided on both sides of the top of the inner part of the groove 2, and a plug rod 5 is inserted into the plug hole 4. The plug rod 5 is tightly pressed against the inner wall of the plug hole 4, and the plug rod 5 is fixedly connected to the contact surface of the groove block 3. A fire extinguishing ball 6 is clamped at the lower part of the inner part of the groove block 3. The fire extinguishing ball 6 is composed of a foam shell, an internal dry powder driving device, and an ABC dry powder fire extinguishing agent. The outside of the fire extinguishing ball device is wrapped with a cross-shaped lead. When the external lead is ignited, the driving medium is activated, the shell quickly expands and ruptures, and the dry powder fire extinguishing agent is quickly sprayed into the protected area. And quickly spread to the surroundings, forming a fully flooded fire extinguishing state. The flame is extinguished under the physical and chemical dual effects of the dry powder fire extinguishing agent. A lead 7 is provided below the fire extinguishing ball 6. A baffle 8 is attached to the lower surface of the substrate 1. A plurality of through holes 9 are evenly opened on the upper surface of the baffle 8. A plug 10 is provided inside the through hole 9. The plug 10 is made of paraffin, also known as crystalline wax, which is usually a white, colorless and odorless waxy solid that melts at 47°C-64°C. The melting point can be controlled by adding polyolefin additives. Standpipes 11 are inserted into the four corners of the lower surface of the baffle 8. The outer wall of the standpipe 11 is tightly pressed against the contact surface of the substrate 1. Bolts 12 are provided inside the standpipe 11. A part of the bolt 12 can pass through the baffle 8 and the substrate 1 in sequence through the standpipe 11. The through hole 9 is a tapered hole, which can increase the stability between the plug 10 and the through hole 9. The top of the outer wall of the standpipe 11 is a tapered structure, which can facilitate the standpipe 11 to pass through the baffle 8 and insert into the substrate 1.

[0017] During the use of the flame-retardant PVC board, the operator first uses the bolt 12 to insert the interior of the riser 11 and successively penetrate the baffle 8 and the base plate 1, and installs the bolt 12 to the top of the installation space (distribution room or distribution cabinet, etc.). When an open flame is generated inside the installation space and leans against the surface of the baffle 8, the baffle 8 and the base plate 1 both have certain flame retardant properties and will not play a combustion-supporting effect when exposed to heat. The baking of the open flame will cause the internal seal 10 of the through hole 9 to melt and fall off. At this time, the through hole 9 will be in an open state, and then the open flame will ignite the lead 7 through the through hole 9. At this time, the driving medium of the fire extinguisher 6 is activated, and the shell quickly expands and ruptures, and the internal dry powder fire extinguishing agent quickly fills the internal cavity of the groove 2. Part of the dry powder fire extinguishing agent can be quickly sprayed outward through the through hole 9 and quickly diffused, which can effectively suppress or slow down the spread of the open fire generated in the installation space, thereby improving the fire safety performance during installation, and enhancing the market competitiveness of similar products, which is convenient for promotion, sales and use.
