Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC pipe technology, specifically to a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe. Background Technology
[0002] PVC pipes are made of polyvinyl chloride as the main raw material, with the addition of stabilizers, lubricants and other additives, and are formed by hot pressing. PVC pipes are lightweight, non-stick and have high pressure resistance, making them highly favored in the engineering industry.
[0003] Currently, PVC pipes have poor thermal stability and are prone to degradation in high-temperature environments. They are also prone to bending under stress, which affects the transport of liquids. Carbon fiber, on the other hand, has high thermal stability and strength, and is also lightweight. Therefore, we propose a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe. Utility Model Content
[0004] The purpose of this invention is to provide a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe, which has the advantages of improving the high-temperature resistance and strength of PVC pipe and improving its applicability. It solves the problems of poor thermal stability of current PVC pipe, easy degradation in high-temperature environment, and easy bending under stress, which affects the liquid transportation. Carbon fiber has high thermal stability and strength, and is also lightweight.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe, comprising a buffer sleeve, a carbon fiber pipe and a PVC inner pipe, wherein the outer surface of the PVC inner pipe is provided with a heat insulation coating, the outer surface of the PVC inner pipe is fixedly sleeved with a carbon fiber pipe, and the outer surface of the carbon fiber pipe is fixedly sleeved with a buffer sleeve.
[0006] Preferably, the inner wall of the PVC inner tube is provided with a non-stick coating. The non-stick coating can prevent impurities from adhering to the inner wall of the PVC inner tube and forming scale, thus effectively preventing blockage inside the PVC inner tube.
[0007] Preferably, the outer surface of the PVC inner tube is provided with a plurality of straight protrusions arranged in a ring array at equal intervals, and the inner wall of the carbon fiber tube is provided with a plurality of straight grooves arranged in a ring array at equal intervals, with the straight protrusions located inside the straight grooves. The straight protrusions and the PVC inner tube are integrally formed, which improves the strength of the PVC inner tube itself. At the same time, when the carbon fiber tube is sleeved on the outer surface of the PVC inner tube, the straight protrusions are inserted into the straight grooves, which restricts the rotation between the carbon fiber tube and the PVC inner tube and improves the bonding strength between the carbon fiber tube and the PVC inner tube.
[0008] Preferably, the outer surface of the buffer sleeve is provided with a spiral protrusion strip, which is integrally formed with the buffer sleeve. When the buffer sleeve is subjected to external impact force, the impact force will first contact the spiral protrusion strip, thereby improving the buffer performance of the buffer sleeve. In addition, the spiral protrusion strip can effectively prevent the outer surface of the buffer sleeve from directly contacting the object, thus effectively preventing wear on the outer surface of the buffer sleeve and extending the service life of the buffer sleeve.
[0009] Preferably, the outer surface of the buffer sleeve is provided with a wear-resistant coating, which can improve the wear resistance of the outer surface of the buffer sleeve, thereby extending the service life of the buffer sleeve. At the same time, the wear-resistant coating also plays an insulating role, effectively preventing the aging and oxidation of the buffer sleeve.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model improves the high-temperature resistance and strength of PVC pipes and enhances their applicability by incorporating a PVC inner tube, a heat-insulating coating, a carbon fiber tube, and a buffer sleeve. The heat-insulating coating between the PVC inner tube and the carbon fiber tube prevents external high temperatures from affecting the PVC inner tube, thus improving its high-temperature resistance. The carbon fiber tube on the outer surface of the PVC inner tube increases its strength, making it less prone to bending under stress. The buffer sleeve on the outer surface of the carbon fiber tube acts as a buffer when the carbon fiber tube is subjected to external impact, preventing the brittle carbon fiber tube from breaking under impact.
[0012] 2. This utility model improves the bonding strength between the carbon fiber tube and the PVC inner tube by setting straight protrusions and straight grooves. The straight protrusions and the PVC inner tube are integrally formed, which improves the strength of the PVC inner tube itself. At the same time, when the carbon fiber tube is sleeved on the outer surface of the PVC inner tube, the straight protrusions are inserted into the straight grooves, which restricts the rotation between the carbon fiber tube and the PVC inner tube and improves the bonding strength between the carbon fiber tube and the PVC inner tube.
[0013] 3. This utility model achieves the effect of further improving the buffering performance of the buffer sleeve by setting a spiral protrusion. The spiral protrusion strip and the buffer sleeve are integrally formed. When the buffer sleeve is subjected to external impact force, the impact force will first contact the spiral protrusion strip, improving the buffering performance of the buffer sleeve. Moreover, the spiral protrusion strip can effectively avoid direct contact between the outer surface of the buffer sleeve and the object, thus effectively avoiding wear on the outer surface of the buffer sleeve and extending the service life of the buffer sleeve.

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
[0019] Example 1
[0020] like Figure 1-Figure 3 As shown, this utility model proposes a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe, including a buffer sleeve 1, a carbon fiber tube 4, and a PVC inner tube 5. The outer surface of the PVC inner tube 5 is provided with a heat-insulating coating 8, which prevents external high temperatures from affecting the PVC inner tube 5 and improves its high-temperature resistance. The carbon fiber tube 4 is fixedly sleeved on the outer surface of the PVC inner tube 5, which improves the strength of the PVC inner tube 5, making it less prone to bending under stress. The buffer sleeve 1 is fixedly sleeved on the outer surface of the carbon fiber tube 4. The inner wall of the PVC inner tube 5 is provided with a non-stick coating 7, which prevents impurities from adhering. The scale formed on the inner wall of the PVC inner tube 5 effectively prevents blockage inside the PVC inner tube 5. The outer surface of the PVC inner tube 5 is provided with a number of straight protrusions 6 in a ring array at equal intervals. The inner wall of the carbon fiber tube 4 is provided with a number of straight grooves 9 in a ring array at equal intervals, and the straight protrusions 6 are located inside the straight grooves 9. The straight protrusions 6 and the PVC inner tube 5 are integrally formed, which improves the strength of the PVC inner tube 5 itself. At the same time, when the carbon fiber tube 4 is sleeved on the outer surface of the PVC inner tube 5, the straight protrusions 6 are inserted into the straight grooves 9, which restricts the rotation between the carbon fiber tube 4 and the PVC inner tube 5 and improves the bonding strength between the carbon fiber tube 4 and the PVC inner tube 5.
[0021] In this embodiment, the heat insulation coating 8 between the PVC inner tube 5 and the carbon fiber tube 4 can prevent the high temperature of the outside from affecting the PVC inner tube 5 and improve the high temperature resistance of the PVC inner tube 5. The carbon fiber tube 4 on the outer surface of the PVC inner tube 5 can improve the strength of the PVC inner tube 5, making the PVC inner tube 5 less prone to bending after being subjected to force. The buffer sleeve 1 on the outer surface of the carbon fiber tube 4 plays a buffering role when the carbon fiber tube 4 is subjected to external impact force, so as to prevent the brittle carbon fiber tube 4 from breaking when subjected to impact force.
[0022] Example 2
[0023] like Figure 1 As shown, the present invention proposes a carbon fiber surface-modified reinforced high-temperature resistant PVC pipe. Compared with Embodiment 1, this embodiment further includes a spiral protrusion 2 on the outer surface of the buffer sleeve 1. The spiral protrusion 2 and the buffer sleeve 1 are integrally formed. The outer surface of the buffer sleeve 1 is provided with a wear-resistant coating 3. The wear-resistant coating 3 can improve the wear resistance of the outer surface of the buffer sleeve 1, thereby extending the service life of the buffer sleeve 1. At the same time, the wear-resistant coating 3 also plays an insulating role, effectively preventing the aging and oxidation of the buffer sleeve 1.
[0024] In this embodiment, when the buffer sleeve 1 is subjected to external impact force, the impact force will first contact the spiral protrusion 2, which improves the buffer performance of the buffer sleeve 1. In addition, the spiral protrusion 2 can effectively prevent the outer surface of the buffer sleeve 1 from directly contacting the object, thus effectively avoiding wear on the outer surface of the buffer sleeve 1 and extending the service life of the buffer sleeve 1.
[0025] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
