Description

Technical Field

[0001] The utility model relates to the technical field of EPE, in particular to an environment-friendly flame-retardant EPE. Background Technique

[0002] Flame-retardant EPE, also known as flame-retardant Ethylene-Propylene Vinyl Acetate (EPE) or flame-retardant Expandable Polyethylene (EPE), is a material made of polyethylene-vinyl acetate copolymer or polyethylene resin that has been specially treated. This material is produced through a physical foaming process to form a lightweight, soft, closed-cell structure containing a large number of tiny bubbles, similar to the synthetic fibers of natural pearls. On the basis of maintaining the excellent physical properties of the original EPE, flame-retardant EPE has enhanced flame-retardant performance. That is, when encountering a fire source, it can delay the spread of the fire, reduce the spread of the flame, and even extinguish the flame on its own, greatly reducing the risk of fire. The characteristics and applications of flame-retardant EPE are as follows: 1. Safe and environmentally friendly: non-toxic, harmless, and produces less smoke when burning, meeting environmental protection standards and being widely used in places with strict fire prevention requirements. 2. Widely applied: used in electronic and electrical packaging, furniture, automotive interiors, building insulation, toys, medical equipment, clothing padding materials, aviation supplies, sports protection equipment, etc. 3. Good shock-proof performance: buffering, shock-proof, sound-absorbing, heat-insulating, heat-preserving, and shock-absorbing, with significant protection effects. 4. Economical and durable: light in weight, easy to process, cut, sew, can be printed, bonded, reused, and has high cost-effectiveness. Flame retardant treatment is usually achieved by adding flame retardants, which are mixed during the material production process or added during the post-treatment stage to change the chemical structure of the material so that it chars at high temperatures and is not easily flammable. The flame-retardant grade of flame-retardant EPE needs to meet different standards in various countries and regions, such as UL94723, GB8626, etc., and is widely accepted and recognized to ensure the compliance and safe use of products.

[0003] The Chinese invention patent with the application number CN220409905U discloses an environment-friendly flame-retardant polyethylene EPE. This patent relates to the technical field of EPE. Honeycomb layers are provided on both the upper and lower sides of the first EPE layer, a flame-retardant layer is provided outside the honeycomb layer, EPE partitions are fixedly arranged in several honeycomb holes of the honeycomb layer, elastic water balls are arranged in pairs in several honeycomb holes and are in contact with the upper and lower side walls of the EPE partitions, a woven layer is provided outside the flame-retardant layer, and a second EPE layer is provided outside the woven layer. It can not only improve the flame-retardant performance of EPE through the flame-retardant characteristics of some materials, but also can extinguish fire to a certain extent in a small area to avoid the continuous large-scale spread of the fire.

[0004] Although the flame-retardant cotton device in the prior art achieves the effect of multi-layer flame retardancy during use, the structure of the flame-retardant cotton is single, and only using the chemical flame-retardant effect of the flame-retardant cotton will greatly reduce the flame-retardant use effect of the flame-retardant cotton, which is not conducive to the full utilization of materials. Summary of the Invention

[0005] The purpose of the present utility model is to solve the deficiencies existing in the prior art, and a kind of environment-friendly flame-retardant EPE is proposed.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] An environment-friendly flame-retardant EPE includes a ferrule, and further includes:

[0008] A flame-retardant component, which includes a frame arrayedly inserted and installed inside the ferrule. The structure of the frame is triangular, and a gasket is filled and installed at the corner parts inside the frame, and a wire core is arranged in the middle part of the gasket;

[0009] The wire core includes a colloid, and the outside of the colloid is wrapped with EPE, the outside of the EPE is wrapped with silicon carbide, and the outside of the silicon carbide is wrapped and installed with quartz.

[0010] As a further technical solution, a buffer helix is wrapped and installed around the wire core.

[0011] As a further technical solution, the frames are staggered to form a parallelogram structure.

[0012] As a further technical solution, the buffer helix is ​​fitted and connected with the gasket and the wire core.

[0014] Compared with the prior art, the present utility model provides an environment-friendly flame-retardant EPE, which has the following beneficial effects:

[0015] Through the set flame-retardant component structure, the flame-retardant cotton is mainly distributed in layers and arrays by means of the framework, and at the same time, the flame-retardant effect of the flame-retardant cotton is increased by using the outer strengthening structure. Among them, the main frame is triangular in structure, and this structure has a certain structural strength during the burning process of the device, which can prevent the EPE from collapsing as a whole during the burning process, thereby affecting the rest of the structure. The gasket filled at the inner corner parts of the frame serves to increase the support effect of the corner parts of the device, and at the same time, the gasket itself has a physical isolation effect. The buffer helix arranged in the middle part of the gasket can increase the flexibility of the device and prevent it from hardening during the burning process. The present device mainly fills the EPE inside the wire core. Among them, quartz, silicon carbide and EPE are all fireproof materials, and the colloid is a material to increase the flexibility of the device. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Embodiment 1: Refer to Figure 1 - Figure 4 , an environmentally friendly flame-retardant EPE, including a ferrule 1, and the ferrule 1 is the external structure of the whole device. It also includes:

[0024] A flame-retardant component 2, which uses various structures to achieve a stronger flame-retardant effect, and at the same time ensures that the overall structure will not collapse and break during the burning process. The flame-retardant component 2 includes a frame 3 that is arrayedly inserted and installed inside the ferrule 1. The triangular structure of the frame 3 can increase the structural strength of the device. The structure of the frame 3 is triangular, and a pad 4 is filled and installed at the corner parts inside the frame 3. The function of the pad 4 is to support the internal structure of the frame 3. A core wire 5 is arranged in the middle of the pad 4, and the core wire 5 is the main fireproof material of the device;

[0025] The core wire 5 includes a glue 10, and the glue 10 is used to increase the elasticity of the core wire 5. The outside of the glue 10 is wrapped with an EPE 9, the outside of the EPE 9 is wrapped with silicon carbide 8, and the outside of the silicon carbide 8 is wrapped and installed with quartz 7. The EPE 9, silicon carbide 8, and quartz 7 are all fireproof materials.

[0026] An environmentally friendly flame-retardant EPE, a buffer helix 6 is installed around the periphery of the wire core 5. The function of the buffer helix 6 is to increase the bending effect of the material in a fire and avoid the occurrence of overall fracture.

[0027] An environmentally friendly flame-retardant EPE, the frames 3 are staggered to form a parallelogram structure, which is easy to be flattened, making the application range of the overall device wider.

[0028] An environmentally friendly flame-retardant EPE, the buffer helix 6 fits and connects with the gasket 4 and the wire core 5, avoiding a large number of gaps, increasing the oxygen density, and thus reducing the flame-retardant effect.

[0029] An environmentally friendly flame-retardant EPE, the thickness of the EPE 9 is 80% of that of the wire core 5, and the EPE 9 needs to be used as the main material of the wire core 5.

[0030] Working principle:

[0031] In the process of using the present utility model, in order to solve the technical problem that the fireproof effect of the existing EPE is single when used alone, it is designed into a special structure. While taking into account the fireproof effect, the structural strength and flexibility are increased, so that the EPE material shows a stronger fire resistance effect during burning. In terms of the main body structure, we adopt the method of array plugging the triangular frames 3 with the narrow-edge card sleeves 1. The triangular frames 3 have a certain structural strength and can avoid the collapse of the overall structure after burning. We added gaskets 4 at the corner parts inside the frames 3, which have two functions: 1. Increase the mutual independence between the fireproof wire cores 5, thereby avoiding the transfer of fire sources between them. 2. Further increase the structural strength of the frames 3. The function of the buffer helix 6 is to increase the flexibility of the wire core 5 and avoid the occurrence of overall fracture during burning. As the fireproof main body of this device, we use EPE 9, quartz 7 and silicon carbide 8 as fireproof materials; the central part uses the glue 10 to increase the flexibility of the structure and avoid rigidity during burning, thereby reducing the risk of overall fracture.

[0032] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
