Description

Technical Field

[0001] This utility model relates to the field of electric heating tape technology, and in particular to a self-regulating electric heating tape. Background Technology

[0002] Electric heating tape, also known as electric heating cable or electric heating belt, is a device used for heating and insulation. It is mainly used to heat and insulate pipes, containers, or other equipment in cold environments to prevent the medium from freezing or to maintain the temperature of the medium within an ideal range. This strip-shaped heating element is usually composed of conductive and insulating materials and can evenly dissipate heat. Its basic principle is to generate heat through resistance wire or conductive material. When current passes through, electrical energy is converted into heat energy due to resistance, thus generating heat. This heat can be directly transferred to the pipes or equipment that need to be insulated to maintain the temperature of the fluid or medium inside. Therefore, electric heating tape is widely used in many fields such as industry, construction, and agriculture.

[0003] Existing electric heating cables have a wide range of applications, and therefore are often subjected to external impacts and pressures. Prolonged exposure to external impacts can easily damage the internal conductivity of the electric heating cable, affecting its service life. After searching, it was found that the technical solution provided by the utility model with application number CN211982167U also has the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a self-regulating electric heating tape. Through the high elastic deformation performance of the silicone material in the buffer layer, it can reduce the impact force of the object when subjected to partial impact, and can effectively absorb and disperse the impact force. The cavity set inside the silicone can further enhance the elastic deformation of the silicone, so that the silicone can buffer greater forces, improve the safety of the overall equipment, protect the stability of the internal structure, and improve the service life of the electric heating tape.

[0005] This utility model also provides a self-regulating electric heating tape, comprising: a conductive core; a first insulating layer disposed on the outer surface of the conductive core; a conductive plastic layer disposed on the outer surface of the first insulating layer; a reinforcing core disposed inside the conductive plastic layer; a flame-retardant layer disposed on the outer surface of the conductive plastic layer; a waterproof layer disposed on the outer surface of the flame-retardant layer; a metal shielding layer disposed on the outer surface of the waterproof layer; a corrosion-resistant layer disposed on the outer surface of the metal shielding layer; a buffer layer disposed on the outer surface of the corrosion-resistant layer; and a second insulating layer disposed on the outer surface of the buffer layer.

[0006] According to the self-regulating electric heating tape, the buffer layer has multiple cavities arranged in a circular pattern. The buffer layer is made of silicone. The high elastic deformation properties of the silicone material effectively absorb and disperse impact forces. The cavities inside the silicone further enhance its elastic deformation, allowing it to buffer greater forces, thus improving the overall safety of the equipment, protecting the stability of the internal structure, and extending the service life of the electric heating tape.

[0007] According to the self-regulating heating cable, there are two conductive cores distributed from left to right, and the conductive cores are tin-plated copper core wires.

[0008] According to the self-regulating electric heating cable, the outer surface of the metal shielding layer is provided with an anti-ultraviolet coating, which is a fluorocarbon paint coating. The metal shielding layer is made of aluminum alloy and has a mesh braided structure. The metal shielding layer can effectively confine the electromagnetic field generated when the cable is energized within the insulated core, reducing electromagnetic interference to the outside world. Furthermore, the metal shielding layer can provide protection for the electric heating cable. When the electric heating cable is affected by external factors, the metal shielding layer, through its hard metal material, can provide a certain degree of protection for the electric heating cable, improve the mechanical strength of the electric heating cable, prevent internal damage to the electric heating cable, and thus increase the service life of the electric heating cable.

[0009] According to the self-regulating electric heating tape, both the first and second insulation layers are made of polyethylene. The outer surface of the second insulation layer is provided with a waterproof coating, which is an acrylic waterproof coating. The insulation layer can effectively protect the conductor core, prevent moisture from entering the electric heating tape and causing a short circuit, and ensure personal safety by preventing the exposed conductor core from coming into contact with the human body and causing danger. Furthermore, the acrylic waterproof coating on the surface of the second insulation layer can further improve the waterproof performance. The acrylic waterproof coating has a certain water repellency, making it difficult for moisture to adhere to its surface, thereby reducing moisture penetration, protecting the conductive core from the influence of moisture, and increasing the service life of the electric heating tape.

[0010] According to the self-regulating electric heating tape, the flame-retardant layer is made of halogen-free polyolefin, and the waterproof layer is made of polyvinyl chloride. Halogen-free polyolefin has certain flame-retardant properties, which can effectively delay the spread of fire in the event of a fire. In addition, it does not release halogen-containing gases, so that less gas is produced when a fire occurs, thereby reducing the harm to human body and environment.

[0011] According to the self-regulating electric heating cable, the reinforcing core is made of synthetic steel, and the conductive plastic layer is made of PTC material. The reinforcing core is used to increase the tensile strength of the electric heating cable, enabling it to withstand greater tension and pressure, and also enhances its bending resistance, allowing it to maintain its stability under different environments, thereby increasing its service life. The conductive plastic layer is used to automatically limit the temperature. When the resistance of the PTC material is near the Curie temperature, the resistance increases sharply, causing a decrease in output power. When the ambient temperature is lower than the set value, the resistance of the PTC material is lower, and the electric heating cable heats up. When the ambient temperature is higher than the set value, the resistance of the PTC material increases, and the electric heating cable cools down, thus achieving the function of automatically limiting the temperature.

[0012] According to the self-regulating electric heating cable, the corrosion-resistant layer is made of carbon fiber. The corrosion-resistant layer is used to protect the internal conductive core, ensuring that the electric heating cable works normally and extends its service life in a chemically corrosive environment.
