Description

Technical Field

[0001] The utility model relates to the technical field of plastic plates, in particular to a flame-retardant nylon plastic plate. Background Art

[0002] Nylon plastic sheet, also known as polyamide sheet, is a high-strength plastic sheet made of nylon resin through extrusion molding, casting or other plastic processing technology. As a kind of engineering plastic, nylon was first successfully developed by DuPont in the United States in the late 1930s, and quickly gained wide application in many industrial fields due to its excellent comprehensive performance. Nylon plastic sheet is widely used in many fields such as machinery manufacturing, automobile industry, aerospace, electronics, construction and building materials.

[0003] Flame retardant nylon plastic sheet is a functional plastic sheet made by adding flame retardant to nylon raw materials. This sheet retains the original good mechanical properties of nylon, such as high strength, wear resistance, self-lubrication, etc. At the same time, the addition of flame retardant significantly improves the flame retardant properties of the material, that is, it can inhibit or delay the combustion process when encountering fire, reduce the spread of flames, and reduce the generation of smoke and toxic gases, thereby improving the safety of the material.

[0004] Although the flame-retardant nylon plastic sheet in the prior art meets the use requirements to a certain extent, flame retardancy does not mean non-flammability. It will still burn under continuous high temperature or when the flame retardant fails, and its safety is relatively low. Utility Model Content

[0005] The purpose of the utility model is to provide a flame retardant nylon plastic sheet to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flame-retardant nylon plastic sheet, comprising a main structure, a first flame-retardant mechanism is fixedly installed inside the main structure, a plurality of second flame-retardant mechanisms are fixedly installed inside the main structure, the first flame-retardant mechanism comprises a flame-retardant plate, a plurality of air chambers are opened inside the flame-retardant plate, a plurality of through holes are opened inside the flame-retardant plate, the plurality of air chambers are connected through the through holes, and sealing plates are fixedly installed on both the upper and lower surfaces of the flame-retardant plate.

[0007] Preferably, the second flame retardant mechanism comprises a first connecting seat, a glass tube is fixedly mounted on the top of the first connecting seat, a second connecting seat is fixedly mounted on the top of the first connecting seat via the glass tube, and a thermosensitive solution is arranged inside the glass tube.

[0008] Preferably, the main structure includes a base plate and a connecting plate, the first connecting seat is fixedly installed on the top of the base plate, the second connecting seat is fixedly installed on the bottom of the connecting plate, and a spring is sleeved on the outer wall of the glass tube.

[0009] Preferably, a metal mesh is fixedly mounted on the top of the connecting plate, and the metal mesh is fixedly mounted on the bottom of the first flame retardant mechanism.

[0010] Preferably, a mineral isolation layer is fixedly installed on the top of the first flame retardant mechanism, and a protective film is fixedly installed on the top of the mineral isolation layer.

[0011] Preferably, an outer wall of the substrate is fixedly mounted with an edge.

[0012] Preferably, a plurality of ventilation nets are provided on the surface of the edging.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the flame retardant nylon plastic sheet;

[0014] 1. Through the coordination between the flame retardant plate, the air chamber and the sealing plate, a large amount of air is retained inside the plate to play a role of heat insulation. When the plate is heated, the air inside the air chamber flows through the through holes, which is conducive to the uniform distribution and dissipation of heat, and prevents the plate from being partially overheated and reaching the fire resistance limit and failing. When the surface of the plate reaches the fire resistance limit and fails to burn, the high temperature causes the thermosensitive solution to expand and break the glass tube, and under the action of the spring, the second connecting seat and the first connecting seat are quickly disconnected, thereby disconnecting the connection between the substrate and the top burned structure, quickly removing the combustion source, interrupting the combustion chain, and preventing the fire from spreading to the entire plate. The first flame retardant mechanism prevents the plate from burning due to local high temperature, and the second flame retardant mechanism prevents the fire from spreading to the entire plate after the surface of the plate reaches the fire resistance limit and fails to burn.

[0015] 2. The fireproof performance of the material is further enhanced by setting a non-combustible mineral isolation layer, protecting the plastic board from direct damage by the fire source, delaying or preventing the spread of fire, protecting the edge of the main structure by edging, ensuring the circulation of air inside the first flame retardant structure by the ventilation net, and protecting the mineral isolation layer by a protective film to prevent the mineral isolation layer from being damaged by external impact or cutting, and increasing the structural strength of the board by the metal mesh, while further ensuring the uniform distribution of heat in the board.

When the surface of the sheet reaches the fire resistance limit and fails to burn, the high temperature causes the thermosensitive solution 304 to expand and break the glass tube 302, and under the action of the spring 305, the second connecting seat 303 and the first connecting seat 301 are quickly disconnected, thereby disconnecting the substrate 101 from the top burned structure, quickly removing the combustion source, interrupting the combustion chain, and preventing the fire from spreading to the entire sheet;
