Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-frequency transmission cables, in particular to a preparation process of a high-stable-phase cable based on a graphene PTFE composite wrapping tape. BACKGROUND

[0002] In the prior art, silver-plated copper flat tapes are often used as wrapping materials, and there is a lack of layered functional design, which cannot meet multiple performance requirements. Although silver-plated copper flat tapes can provide certain electrical conductivity, they have poor elasticity and are difficult to adapt to deformation requirements during the wrapping process. They are prone to structural instability due to stress concentration. Silver-plated copper flat tapes have poor adaptability to thermal expansion and are prone to significant deformation due to temperature changes. In the existing wrapping process, there is no precise control of the expansion and overlapping areas, and it is difficult to timely address the problem of tight fitting caused by improper expansion or overlapping. The existing technology has no means to judge or control the causes of thermal expansion, resulting in insufficient heat control. Due to the single material performance, the lack of process control and insufficient post-processing, the existing technology cannot solve the problems of tight fitting, poor thermal expansion control and low structural stability.

[0003] Chinese Patent Publication No. CN222952858U discloses a silver-plated copper flat tape for wrapping the outer conductor of a ship cable, which includes a conductor structure (1) for operation; the outer side of the conductor structure (1) can be covered with a flat tape wrapping structure (2), a nested wrapping structure (3) and a cross wrapping structure (4), respectively; the flat tape wrapping structure (2), the nested wrapping structure (3) and the cross wrapping structure (4) are coated with a corrosion-resistant layer (6) and a conductive layer (7); it can be seen that the silver-plated copper flat tape for wrapping the outer conductor of the ship cable has the problems of tight fitting, insufficient heat control, and bulging and bubbling after thermal expansion. SUMMARY

[0004] To this end, the present application provides a preparation process of a high-stable-phase cable based on a graphene PTFE composite wrapping tape to overcome the problems of insufficient heat control, difficulty in adapting to deformation requirements during the wrapping process, and structural instability due to stress concentration in the prior art.

[0005] To achieve the above-mentioned purpose, the present application provides a preparation process of a high-stable-phase cable based on a graphene PTFE composite wrapping tape, which comprises: controlling the take-up reel to pull the to-be-wrapped body to the corresponding wrapping area; corresponding wrapping tapes of the corresponding layers are respectively conveyed to the corresponding wrapping positions of the wrapping area to form a high-stable-phase test cable, the wrapping tapes including inner, outer and intermediate layer wrapping tapes; the thickness of a plurality of detection points of the high-stable-phase test cable and the width of the wrapping tape overlapping area are respectively obtained to determine the expansion area according to the thickness and the width; The fitting risk processing mode is determined according to a coincidence ratio of the overlap area of the wrapping tape and the expansion area, including adjusting the distance between the guide rollers, or adjusting the distance between the guide rollers and the body to be wrapped according to the expansion length of the expansion area in the non-overlap area, and adjusting the wrapping angle according to the area proportion of the layered expansion area; The body to be wrapped is continuously wrapped according to the fitting risk processing mode to form a basic high-stability phase cable; The basic high-stability phase cable is sequentially subjected to plasma surface treatment and staged heat pressing and curing to output a finished high-stability phase cable.

[0006] Further, the expansion area is the largest curved surface area surrounded by the corresponding detection point positions in the thickness abnormal area on the high-stability phase test cable that meet the preset width condition, wherein, The thickness abnormal area is a curved surface area surrounded by all detection point positions on the high-stability phase test cable that meet the condition of thickness greater than the preset thickness.

[0007] Further, the preset width condition is that the width of the wrapping tape overlap area is less than the preset width.

[0008] Further, the adjusting the distance between the guide rollers includes: Comparing the coincidence ratio with a preset coincidence ratio; If the coincidence ratio is greater than the preset coincidence ratio, it is determined that the fitting risk exceeds the allowable range, and the distance between the guide rollers is increased; Wherein, the distance between the guide rollers and the coincidence ratio are positively correlated.

[0009] Further, the coincidence ratio is the ratio of the sum of the areas of the expansion areas in the wrapping tape overlap area to the total area of the expansion areas.

[0010] Further, the adjusting the distance between the guide rollers and the body to be wrapped according to the expansion length of the expansion area in the non-overlap area includes, If the coincidence ratio is less than or equal to the preset coincidence ratio, it is determined that the active shrinkage risk of the wrapping tape does not meet the requirements, and the expansion length of the expansion area in the non-overlap area is obtained; Comparing the expansion length of the expansion area with a preset length; If the expansion length of the expansion area is greater than the preset length, the distance between the guide rollers and the body to be wrapped is reduced; Wherein, the distance between the guide rollers and the body to be wrapped and the expansion length of the expansion area are negatively correlated.

[0011] Further, the adjusting the wrapping angle according to the area proportion of the layered expansion area includes: Obtaining the total area of the layered expansion area; obtaining a total area of the inflation area of the non-overlapping area; comparing the area ratio with a preset area ratio; if the area ratio is greater than the preset area ratio, reducing the wrapping angle to increase the overlapping area.

[0012] Further, the wrapping angle is negatively correlated with the area ratio.

[0013] Further, the layered inflation area is an inflation area in which the maximum horizontal projection area of a three-dimensional space surrounded by a wrapping tape corresponding to a detection point position in the non-overlapping area with a thickness greater than a preset thickness is greater than the horizontal projection area of the detection point position on the wrapping tape.

[0014] Further, the area ratio is the ratio of the total area of the layered inflation area in the unit monitoring area to the total area of the inflation area of the non-overlapping area.

[0015] Compared with the prior art, the present application has the beneficial effects that by setting the thickness of the detection point positions of the high-stable phase test cable and the width of the overlapping area of the wrapping tape, the inflation area is determined, and during the wrapping process of the to-be-wrapped body, due to the heat increase caused by the rotation of the reel and the friction between different layers of the wrapping tape during the movement of the wrapping tape from the corresponding position on the reel to the winding position, the wrapping tape may expand at some positions where heat is more concentrated after entering the to-be-wrapped body, thereby causing errors in the wrapping process. If the wrapping tape expands on the overlapping area between the wrapping tapes that have been wound onto the to-be-wrapped body, the wrapping tape on the side of the wrapping tape on the opposite side of the traction direction is finally covered and pressed by the next turn during the wrapping process, and the side of the overlapping area that is not pressed may shrink in width when the wrapping tape expands, which may cause the risk of poor fit, i.e., the wrapping accuracy in the wrapping process decreases, and the specific wrapping position is inaccurate. Therefore, by determining the fit risk processing mode according to the overlap ratio of the wrapping tape overlapping area and the inflation area, the risk of reduced wrapping accuracy due to the expansion of the wrapping tape is reduced.

[0016] Further, the preparation process of the present application increases the distance between the guide rollers, and when the overlap ratio of the wrapping tape overlapping area and the inflation area exceeds the preset overlap ratio, the distance between the guide rollers is increased to reduce the influence of the heat increase of the wrapping tape due to the heat generated by the space and friction between adjacent layers during the wrapping process of the wrapping tape, which may cause the wrapping tape to expand and the wrapping position to be misaligned.

[0017] Further, the preparation process of the application reduces the risk of slippage of the wrapping tape due to the layered expansion area by reducing the wrapping angle, thereby reducing the risk of layered expansion of the wrapping tape, causing the wrapping tape to be squeezed into two layers, and reducing the accuracy of the wrapping. Therefore, reducing the wrapping angle can reduce the area of the overlapping area, thereby reducing the effect of layered expansion, and further improving the accuracy of the preparation.

[0018] Further, the preparation process of the application adjusts the distance between the guide roller and the body to be wrapped according to the expansion length of the expansion area of the non-overlapping area, to reduce the impact of the preparation accuracy caused by the risk of shrinkage of the wrapping tape due to the expansion of the non-overlapping area, and further improve the accuracy of the preparation.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , which are respectively a flow chart of a preparation process of a high-stability phase cable based on a graphene PTFE composite wrapping tape, a wrapping device structure schematic diagram, a layered expansion type regional structure schematic diagram and an adjusting guide roller spacing flow chart; the preparation process of the high-stability phase cable based on the graphene PTFE composite wrapping tape of the present application embodiment, comprising: Step S1, control the take-up frame 2 to pull the to-be-wrapped body 1 to the corresponding wrapping area; Specifically, the to-be-wrapped body 1 is a core part that needs to be wrapped by a wrapping tape in the cable manufacturing process, wherein the core part is a copper core or a silver-plated copper core that provides electrical conductivity.

[0025] Specifically, the traction device adopts a wheel type traction machine to pull the to-be-wrapped body 1 to the wrapping area at a controllable speed and tension, and maintains a stable conveying speed during the wrapping process.

[0026] Step S2, the wrapping tapes of the corresponding layers are respectively correspondingly conveyed to the corresponding wrapping positions of the wrapping area to form a high-stability phase test cable, the wrapping tapes including inner layer wrapping tapes, outer layer wrapping tapes and intermediate layer wrapping tapes; The wrapping position is a three-dimensional staggered wrapping, and the to-be-wrapped body 1 is wrapped by a plurality of wrapping positions, and the wrapping sequence should follow the inner layer first, the intermediate layer second, and the outer layer last to form a multi-layer composite wrapping structure.

[0027] Step S3, respectively acquiring the thickness of a plurality of detection points of the high-stability phase test cable and the width of the wrapping tape overlapping area, to determine the expansion area according to the thickness and the width; The expansion region is a maximum curved surface region surrounded by corresponding detection points in the thickness abnormal region on the high-stability phase test cable that meet the preset width condition, wherein, The thickness abnormal region is a curved surface region surrounded by all detection points on the high-stability phase test cable that meet the condition of thickness greater than the preset thickness.

[0028] The preset width condition is that the width of the wrapping tape overlapping region is less than the preset width.

[0029] Specifically, when the thickness of the detection point on the high-stability phase test cable is greater than the preset thickness, it indicates that the thickness of the point exceeds the allowable range. When the width of the corresponding detection point in the thickness abnormal region on the high-stability phase test cable is less than the preset width, it indicates that the point meets the preset width condition, and the thickness is greater than the preset thickness. Under the conditions that the inner layer wrapping tape single layer thickness is 0.08 mm, the intermediate layer and the outer layer wrapping tape single layer thickness is 0.06 mm, the wrapping line speed is 20 m / min, the wrapping process temperature is 40°C, and the diameter of the body to be wrapped 1 is 2.0 mm, the optional range of the preset thickness is [0.28 mm, 0.35 mm], and the preferred embodiment of the preset thickness is 0.30 mm; the optional range of the preset width is [1.92 mm, 1.97 mm], and the preferred embodiment of the preset width is 1.95 mm.

[0030] In the implementation, an ultrasonic detection array is used to obtain a curved surface region surrounded by all detection points on the high-stability phase test cable that meet the condition of thickness greater than the preset thickness, and then a maximum curved surface region surrounded by corresponding detection points in the thickness abnormal region on the high-stability phase test cable that meet the condition of width less than the preset width is obtained.

[0031] Step S4: determining the fitting risk processing mode according to the overlapping ratio of the wrapping tape overlapping region and the expansion region, including adjusting the guide roller spacing, or adjusting the distance between the guide roller 3 and the body to be wrapped 1 according to the expansion length of the expansion region in the non-overlapping region, and adjusting the wrapping angle according to the area proportion of the layered expansion region; Comparing the overlapping ratio with a preset overlapping ratio; If the overlapping ratio is greater than the preset overlapping ratio, it is determined that the fitting risk exceeds the allowable range, and the guide roller spacing is increased; The guide roller spacing is positively correlated with the overlapping ratio.

[0032] The overlapping ratio is the ratio of the sum of the areas of the expansion regions in the wrapping tape overlapping region to the total area of the expansion region.

[0033] If the overlapping ratio is less than or equal to the preset overlapping ratio, it is determined that the active shrinkage risk of the wrapping tape does not meet the requirements, and the expansion length of the expansion region in the non-overlapping region is obtained. comparing the expansion length of the expansion region with a preset length; if the expansion length of the expansion region is greater than the preset length, reducing the distance between the guide wheel 3 and the body 1 to be wrapped; The area ratio is the ratio of the total area of the layered expansion region in the unit monitoring region to the total area of the non-overlapping region expansion region.

[0034] The distance between the guide wheel 3 and the body 1 to be wrapped is negatively correlated with the expansion length of the expansion region.

[0035] obtaining the total area of the layered expansion region; obtaining the total area of the expansion region of the non-overlapping region; comparing the area ratio with a preset area ratio; If the area ratio is greater than the preset area ratio, the wrapping angle is reduced to increase the overlapping area.

[0036] The layered expansion region is an expansion region in which the maximum horizontal projection area of the three-dimensional space surrounded by the wrapping belt corresponding to the corresponding detection point position in the non-overlapping region that satisfies the thickness greater than the preset thickness is greater than the horizontal projection area corresponding to the detection point position on the wrapping belt.

[0037] Specifically, when the coincidence ratio is greater than the preset coincidence ratio, it indicates that the thermal expansion effect is dominated by the risk of adhesion; when the coincidence ratio is less than or equal to the preset coincidence ratio, it indicates that the thermal expansion effect is dominated by the risk of active shrinkage of the wrapping belt. Under the conditions that the inner layer wrapping belt single layer thickness is 0.08mm, the intermediate layer and the outer layer wrapping belt single layer thickness is 0.06mm, the wrapping line speed is 20m / min, the wrapping process temperature is 40℃, the body 1 to be wrapped diameter is 2.0mm, the preset thickness is 0.30mm, and the preset width is 1.95mm, the optional implementation range of the preset coincidence ratio is [20%, 30%], and the preferred embodiment of the preset coincidence ratio is 25%.

[0038] Specifically, when the difference between the coincidence ratio and the preset coincidence ratio is within 2%, the guide wheel spacing is increased by 1cm; when the difference between the coincidence ratio and the preset coincidence ratio is greater than the preset coincidence ratio difference by more than 2%, the guide wheel spacing is increased by 0.1cm for every 1% increase. In a specific embodiment, when the coincidence ratio is 30%, the preset coincidence ratio is 25%, and the current guide wheel spacing is 20cm, the increased guide wheel spacing is 20cm+1cm+(30-25-2)÷1×0.1=21.3cm.

[0039] In implementation, when the coincidence ratio is less than or equal to the preset coincidence ratio, the laser range finder is used to obtain the expansion length of the expansion region in the non-overlapping region, and is compared with the preset length.

[0040] Specifically, when the expansion length of the expansion region in the non-overlapping region is greater than the preset length, the expansion length of the expansion region in the non-overlapping region exceeds the allowable range. Under the conditions that the single-layer thickness of the inner layer wrapping tape is 0.08 mm, the single-layer thickness of the intermediate layer and the outer layer wrapping tape is 0.06 mm, the wrapping wire speed is 20 m / min, the wrapping process temperature is 40℃, the diameter of the body to be wrapped 1 is 2.0 mm, the preset thickness is 0.30 mm, the preset width is 1.95 mm, and the preset overlap ratio is 25%, the optional implementation range of the preset length is [1.0 mm, 2.0 mm], and the preferred embodiment of the preset length is 1.5 mm.

[0041] Specifically, when the expansion length of the expansion region in the non-overlapping region is greater than the preset length by a difference within 0.2 mm, the distance between the guide wheel 3 and the body to be wrapped 1 is reduced by 0.1 cm, and when the expansion length of the expansion region in the non-overlapping region is greater than the preset length by a difference exceeding 0.2 mm, the distance between the guide wheel 3 and the body to be wrapped 1 is correspondingly reduced by 0.01 cm for every 0.1 mm. In a specific embodiment, when the expansion length of the expansion region in the non-overlapping region is 2.0 mm, the preset length is 1.5 mm, and the current distance between the guide wheel 3 and the body to be wrapped 1 is 5 cm, the reduced distance between the guide wheel 3 and the body to be wrapped 1 is 5 cm-0.1 cm-(2.0 mm-1.5 mm-0.2 mm) ÷ 0.1 mm × 0.01 cm = 4.87 cm.

[0042] In implementation, a laser range finder is used to obtain the cross-sectional area of the maximum cross section 7 of the three-dimensional expansion region in the non-overlapping region above the surface of the wrapping tape and the cross-sectional area of the expansion plane region 8 at the bottom of the three-dimensional expansion region on the wrapping tape to determine the layered expansion region, and a 3D laser profile scanner is used to obtain the area of the layered expansion region and the area of the expansion region in the non-overlapping region. The ratio of the total area of the layered expansion region to the total area of the expansion region in the non-overlapping region is compared with the preset area ratio, and when the ratio of the total area of the layered expansion region to the total area of the expansion region in the non-overlapping region is greater than the preset area ratio, the sliding risk caused by the layered expansion region exceeds the allowable range. Under the conditions that the single-layer thickness of the inner layer wrapping tape is 0.08 mm, the single-layer thickness of the intermediate layer and the outer layer wrapping tape is 0.06 mm, the wrapping wire speed is 20 m / min, the wrapping process temperature is 40℃, the diameter of the body to be wrapped 1 is 2.0 mm, the preset thickness is 0.30 mm, the preset width is 1.95 mm, the preset overlap ratio is 25%, and the preset length is 1.5 mm, the optional implementation range of the preset area ratio is [10%, 15%], and the preferred embodiment of the preset area ratio is 13%.

[0043] Specifically, when the difference between the area ratio and the preset area ratio is within 2%, the wrapping angle is reduced by 1°; when the difference between the area ratio and the preset area ratio exceeds 2%, the wrapping angle is reduced by 0.1° for each 1% exceeding 2%. In a specific embodiment, when the area ratio is 17%, the preset area ratio is 13%, and the current wrapping angle is 60°, the reduced wrapping angle is 60°-1°-(17%-13%-2%) ÷1%×0.1°=58.8°.

[0044] Step S5, continue to wrap the to-be-wrapped body 1 according to the lamination risk processing mode to form a basic high-stable-phase cable; The wrapping device is continuously operated according to the set guide wheel spacing, the distance between the guide wheel 3 and the to-be-wrapped body 1, and the wrapping angle, and the inner layer high-conductivity graphene PTFE tape, the intermediate layer graphene PTFE composite shielding tape, and the outer layer high-elasticity modified PTFE tape are sequentially wound on the surface of the to-be-wrapped body 1 to form a wrapping structure.

[0045] Specifically, the inner layer wrapping tape 4 is a high-conductivity graphene / PTFE tape with a graphene content of 8%; the intermediate layer wrapping tape 5 is embedded with a graphene / PTFE composite shielding tape; and the outer layer wrapping tape 6 is a high-elasticity modified PTFE tape with 5% nano ceramic particles added.

[0046] The core structure of the basic high-stable-phase cable relies on the synergistic effect of the three layers of wrapping tapes: the inner layer provides high conductivity, the intermediate layer realizes shielding function, and the outer layer guarantees elasticity and anti-deformation ability.

[0047] Step S6, sequentially perform plasma surface treatment and staged heat pressing and curing on the basic high-stable-phase cable to output a finished high-stable-phase cable.

[0048] In implementation, the plasma surface treatment is a chemical modification process performed on the surface of the basic high-stable-phase cable to improve the interlayer adhesion.

[0049] Specifically, a normal-pressure plasma spray gun is used to bombard the surface of the basic cable with high-energy particles of plasma such as argon and oxygen plasma, break the chemical bonds on the surface of the wrapping tape, introduce hydroxyl and carboxyl active groups, remove surface impurities, and enhance the bonding ability of the contact surface of each layer of wrapping tapes.

[0050] In implementation, the staged heat pressing and curing is a process of fully fusing and setting the wrapping tape material by gradient heating and applying pressure.

[0051] Specifically, a vertical heat pressing and curing tower is used to cure for 30 minutes under the conditions of a temperature of 80°C and an air pressure of 0.5 MPa to eliminate interlayer gas residues, and to cure for 60 minutes under the conditions of a temperature of 160°C and an air pressure of 2 MPa to promote PTFE sintering and graphene network fusion.

[0052] By gradient temperature control and pressure assistance, the micro voids inside the basic cable are eliminated, and the integrity of the three-layer wrapping tape is enhanced.

[0053] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the protection scope of the present application.
