Description

Technical Field

[0001] The utility model relates to the technical field of polymer PVC pipes, in particular to a high temperature resistant and flame retardant polymer PVC pipe. Background Art

[0002] PVC pipe, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is popular and widely used in the world today. Its global usage ranks second among various synthetic materials and is widely used in various fields in modern times.

[0003] For example, the utility model with application number 202221565128.9 discloses a high-temperature resistant and flame-retardant polymer PVC pipe. This technical solution adopts a flame-retardant component. When combustion occurs, the flame-retardant gas strip and the flame-retardant bag rupture, allowing the flame-retardant gas and flame-retardant powder to overflow, thereby extinguishing the flame, thereby achieving a strong flame-retardant effect and avoiding serious losses in the event of a fire. When in use, the high-temperature resistant layer and the steel belt layer are used to avoid deformation at high temperatures. The heat dissipation component utilizes the principle of heat conduction to facilitate timely heat dissipation to the outside, thereby reducing heat accumulation and further improving the high-temperature resistance effect.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although this type of high-temperature resistant and flame-retardant polymer PVC pipe uses the principle of heat transfer to transport heat to the outside through the heat-conducting rod, the contact area between the heat-conducting rod and the pipe is small when only the evacuation arrangement is used, resulting in a poor heat dissipation effect on the pipe. The heat inside the pipe cannot be evacuated in time, and the flame-retardant and high-temperature resistant effect is greatly reduced.

[0006] Therefore, a high temperature resistant and flame retardant polymer PVC pipe is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a high temperature resistant and flame retardant polymer PVC pipe to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A high-temperature resistant and flame-retardant polymer PVC pipe comprises a PVC pipe body, wherein a high-temperature resistant layer 1 is arranged inside the PVC pipe body, a flame-retardant layer is fixed on the outside of the PVC pipe body, a heat-conducting layer 1 is fixed on the outside of the flame-retardant layer, heat-conducting blocks are evenly arranged on the outside of the heat-conducting layer 1, a heat-conducting layer 2 is fixed on the end of the heat-conducting block, a high-temperature resistant layer 2 is fixed on the outside of the heat-conducting layer 2, heat dissipation holes are evenly opened on the outside of the high-temperature resistant layer 2, a protective net is fixedly connected to the outside of the heat dissipation hole, and a protective component is arranged on the outside of the protective net.

[0010] Preferably, the protective component comprises a wrapping ring and elastic ribs, the wrapping ring is evenly arranged on the outside of the protective net, the elastic ribs are evenly fixed inside the wrapping ring, and shaping blocks are filled between the elastic ribs.

[0011] Preferably, a protective layer is fixed on the outer side of the wrapping ring, and wear-resistant sheets are evenly arranged on the outer side of the protective layer.

[0012] Preferably: the outer sides of the heat-conducting blocks are filled with high-temperature resistant fillers, and the heat-conducting blocks are all inverted trapezoidal blocks.

[0013] Preferably, a coating layer is arranged on the outer side of the protective layer, and the coating layer is an anti-corrosion coating.

[0014] Preferably, an anti-skid layer is arranged on the outer side of the wear-resistant sheet, and anti-skid patterns are arranged on the anti-skid layer.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a high-temperature resistant and flame-retardant polymer PVC pipe. Through the coordinated use of a PVC pipe body, a high-temperature resistant layer 1, a flame-retardant layer, a heat-conducting layer 1, a heat-conducting block, a high-temperature resistant layer 2, heat dissipation holes, a protective net and a heat-conducting layer 2, the heat inside the PVC pipe body is transferred to the heat-conducting block through the large-area-covered heat-conducting layer 1, and is quickly transferred to the fully-covered heat-conducting layer 2 through the large-area end of the heat-conducting block, and is quickly discharged through the heat-dissipating holes. The external high temperature needs to be transferred inwards through the heat-dissipating holes first to enter the heat-conducting layer 2, which increases the difficulty of heat transfer. At the same time, the contact surface between the heat-conducting block and the heat-conducting layer 1 is small, which makes the heat transfer inwards slow, and can facilitate the rapid transfer and evacuation of the heat inside the PVC pipe body to the outside, avoiding the high temperature on the PVC pipe body. Aggregation causes deformation and melting of the PVC pipe body, and at the same time hinders the high temperature on the outside from being transmitted inward, thereby improving the high temperature resistance of the outside, thereby improving the protective power of the high-temperature resistant and flame-retardant polymer PVC pipe; through the coordinated use of the wrapping ring, elastic ribs and shaping blocks, the elastic shaping blocks and elastic ribs play a buffering and protective role on the outside of the PVC pipe body, enhance the overall firmness of the PVC pipe body, reduce damage to the PVC pipe body such as collision and impact, thereby improving the firmness of the high-temperature resistant and flame-retardant polymer PVC pipe; through the coordinated use of the protective layer and the wear-resistant sheet, the protective layer protects the wrapping ring, and the wear-resistant sheet not only improves the protective effect, but also improves the wear resistance of the outside, thereby improving the protective effect of the high-temperature flame-retardant polymer PVC pipe.

The high temperature from the outside needs to first pass through the heat dissipation holes 7 to enter the heat conductive layer 2 14, which increases the difficulty of heat transfer.
