[0029] Reference Figure 1-3 A basalt fiber composite tube embodiment of the present invention is further described.

[0030] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0031] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0032] A basalt fiber composite tube is prepared from layered materials, which include self-adhesive polymer materials, basalt fibers and thermoplastic polymer engineering plastics from the inside to the outside, and are formed by a winding process and an outer coating process. The raw material components and each component are calculated by weight as follows: 20-25 parts of self-adhesive polymer materials, 80-100 parts of basalt fibers, 5-6 parts of curing agents, and 10-15 parts of thermoplastic polymer engineering plastics. The curing agent is an acid glycoside curing agent. The specific production includes the following steps: S1, analyzing the composition of basalt rocks, and selecting basalt with a texture that meets the fiber molding standard;

[0033] S2, melting the basalt rock selected in step S1 at a high temperature of 1500° C.-1600° C., and monitoring the viscosity of the melt in real time. When the viscosity of the melt reaches a target value, the melt is drawn through a drain plate to obtain continuous fibers;

[0034] S3, cooling the continuous fiber obtained in step S2 for standby use;

[0035] In the embodiment of the present invention, basalt is used for melt drawing, the energy consumption in the production process is low, and the material is purely natural, no toxic gas is generated during the melting process, and it is used in the pipe, and the overall structural strength is greatly increased;

[0036] S4. In a dust-free environment, the above materials are prepared into an inner tube, and the inner tube is wound by a traction device;

[0037] S5, the inner tube after winding is coated with an outer layer by injection molding, the mold is placed in a hot press, the coated tube is compacted, the temperature is raised to 260-280°C, and the temperature is kept for 10-30 minutes, and then the pressure of the hot press is increased to 120-150MPa, and then the temperature is increased to 310-350°C at a rate of 50°C per hour, and the temperature is kept for 20-60 minutes, so that the layers are coated and pressurized;

[0038] S6. Place the mold in a cold press for 10 to 30 minutes. During the cold press, the mold is continuously inflated and deflated for 3 to 5 times. The pressure applied by inflation is between 100 and 150 MPa to obtain a finished product.

[0039] In an embodiment of the present invention, a basalt fiber composite tube is prepared from layered materials, which include self-adhesive polymer materials, basalt fibers and thermoplastic polymer engineering plastics from the inside to the outside. The tube is formed through a drawing and wrapping process and an outer coating process. The prepared inner tube structure is wrapped with basalt fibers, and then the tube is formed as a whole through an outer coating process. After the inner tube is wrapped, the overall structural strength is higher and the overall service life can be greatly improved.

[0040] At the same time, after the outer layer is injection molded, the mold is hot-pressed and cold-pressed to make the bonding strength between the layers stronger, and the traditional lamination method is changed to injection molding and then hot-pressing and cold-pressing, so that a preliminary full-coverage bond is formed between the outer coating layer and the inner tube layer, avoiding the occurrence of uneven bonding.

[0041] Specifically, in step S4, the specific method of the winding process includes the following steps, and also includes a controller for controlling the outlet speed of the basalt fiber pulling device; a wire passer for passing the basalt fiber; a pressure sensor is provided on the wire passer for real-time monitoring the pressure of the basalt fiber when it is out of the wire, and the monitored pressure is recorded as Pt. The controller includes a monitoring unit for receiving the electrical signal output by the pressure sensor; a comparison unit for setting the pressure value when the outlet speed of the basalt fiber pulling device needs to be controlled as P0, and comparing the received electrical signal with the P0 value; a timing unit for monitoring the time T when the pressure value is greater than P0, and setting T0, when the timing time is greater than T0, the speed of the pulling device needs to be controlled; a control unit for controlling the pulling speed of the pulling device, S40, winding the prepared basalt fiber, and setting a wire passer at the outlet end of the basalt fiber, the wire passer is provided with a pressure sensor for real-time monitoring the pressure of the basalt fiber when it is out of the wire, and the monitored pressure is recorded as Pt;

[0042] S41, within the first time period, the pressure monitored by the pressure sensor is recorded as P1, and the comparison unit compares the received electrical signal with the P0 value. If the P1 value is less than the P0 value, it is determined that the winding speed is stable and monitoring continues;

[0043] S42, if the P1 value is greater than the P0 value, the timing unit intervenes, and the timing unit records the time when the value is greater than the P0 value as T1. When T1 is less than the T value, it is determined that there is a slight freeze, and monitoring continues;

[0044] S43, when T1 is greater than T value, it is judged that the jam is more serious, and it is necessary to control the traction device to stop traction through the control unit, and the outlet device continues to outlet to form a reserved buffer for the outlet, and then start the traction device through the control unit. In the second time period, the pressure monitored by the pressure sensor is recorded as P2, and the comparison unit compares the received electrical signal with the P0 value. If the P2 value is less than the P0 value, it is judged that the winding speed is stable and continues to monitor;

[0045] S44, if the P2 value is greater than the P0 value, it is judged that the jam is serious, and the control unit needs to control the traction device to stop traction, and the outgoing line device continues to outgoing line to form a reserved buffer for the outgoing line, and then the traction device is started by the control unit, and then the outgoing line device and the traction device are reversely controlled to rotate in the opposite direction. In the third time period, the pressure detected by the pressure sensor is recorded as P3, and the comparison unit compares the received electrical signal with the P0 value. If the P3 value is less than the P0 value, it is judged that the jam is gone and monitoring is continued; if the P3 value is greater than the P0 value, it is judged that the jam still exists and manual detection and processing are required;

[0046] S45. Loop steps S40-44.

[0047] The present invention also includes a specific control method for the winding process. Through the cooperation between the controller, the wire guide and the pressure sensor, whether there is a jam in the wire-out process can be monitored in real time, and the traction device is controlled to stop traction, while the wire-out device continues to output the wire to form a reserved buffer for the wire-out, and then the traction device is started by the control unit; or the traction device is controlled to stop traction, while the wire-out device continues to output the wire to form a reserved buffer for the wire-out, and then the traction device is started by the control unit, and then the wire-out device and the traction device are reversely controlled to rotate in reverse; or the jam is handled by manual detection and processing, so as to achieve the effect of continuously ensuring stable winding during the winding process, and the winding force is relatively uniform, so as to form a good winding strength guarantee.

[0048] In the embodiment of the present invention, the outlet device is further provided with a thickness monitor for monitoring the thickness of the basalt fiber remainder on the outlet device, and the warning thickness and the anti-idling thickness of the thickness monitor are set. The warning thickness indicates the minimum thickness of the fiber remainder of the outlet device; the anti-idling thickness is the minimum fiber winding thickness on the outlet device, and the thickness value at which the tension of the outlet device on the fiber begins to decrease. The specific control steps of the outlet device are as follows: S46, judging whether the current thickness is less than the warning thickness;

[0049] S47, if the judgment result is yes, then the pressure detector is used to detect whether the pressure is less than the standard pressure value; if the judgment result is no, then the traction device is controlled to decelerate and rotate, the traction speed is controlled, and the output line amount is controlled;

[0050] If the judgment result is yes, step S47 further includes: S470, judging whether the current thickness is less than the anti-idling thickness, and the anti-idling thickness is less than the warning thickness;

[0051] S471. If the judgment result is yes, the output reverse current is controlled to the outgoing line device to rotate in the reverse direction, and the traction device is stopped and closed within T time. If the judgment result is no, the outgoing line device is controlled to rotate in the reverse direction according to the thickness difference between the current thickness and the anti-idling thickness until the winding is completed.

[0052] In order to cooperate with the above-mentioned winding method and ensure that a relatively consistent winding force can be maintained when winding the inner tube, thereby forming a better winding effect, according to the description of the above-mentioned embodiment, this embodiment adds a detection of the wire outlet margin of the wire outlet device. When the warning thickness margin is reached, it is necessary to control the rotation speed of the wire outlet device, and according to the value detected by the pressure detector, the traction device and the wire outlet device are rotated and controlled to keep the force of the winding fiber at a specific winding tension at all times, thereby ensuring the best winding effect.

[0053] When the outlet device rotates in the reverse direction, the driving force of the traction device must be greater than the driving force brought by the reverse rotation of the outlet device, so that the traction driving force of the traction device can always maintain the traction state. The reverse rotation of the outlet device continuously provides a tight force for the fiber, so that the traction device can form a stable and continuous winding pressure on the inner tube during traction.

[0054] Specifically, the viscosity η of the melt in step S2 is between 0.5Pa·s≤η≤1.5Pa·s. In the present invention, by controlling the viscosity of the melt in step S2, the basalt melt can be drawn evenly and have a stable flow rate in the wire drawing state, and the occurrence of knots can be reduced, the wire drawing effect is good, and the practicability is strong.

[0055] In step S2 of the embodiment of the present invention, a drawing channel 10 is provided on the leak plate 1, and a flow control structure is provided in the drawing channel 10, and the flow control structure is used to control the channel pressure in the drawing channel 10, and the above-mentioned flow control structure includes a expanding structure 11 arranged at the inlet end of the drawing channel 10 and a shrinking structure 12 arranged at the outlet end of the drawing channel 10, the content cavity of the expanding structure 11 is spherical, and the content cavity of the shrinking structure 12 is conical, and the content cavity of the expanding structure 11 and the content cavity of the shrinking structure 12 have overlapping connecting parts 13, the volume of the connecting part 13 is between 1 / 4-1 / 3 of the volume of the content cavity of the expanding structure 11, and the volume of the connecting part 13 is between 1 / 3-1 / 2 of the volume of the content cavity of the shrinking structure 12.

[0056] The present invention sets the flow control structure as the above-mentioned structure so that during the wire drawing process, when the fluid enters the wire drawing channel 10, it first enters the cavity of the expansion structure 11. The inner cavity provides a larger space for the fluid, allowing the fluid to form a buffering effect in the larger space, so that the pressure in the channel will not continue to increase, and a relatively stable pressure is always maintained. Then, as the fluid continues to flow, the fluid enters the cavity of the contraction structure 12. Because the proportion of the connecting part 13 between the expansion structure 11 and the contraction structure 12 that overlaps with each other is controlled, the fluid still has a certain flow pressure intensity after entering the contraction structure 12, reducing the influence of viscosity on subsequent wire drawing, and ensuring a continuous and stable flow channel pressure. Therefore, through the cooperation between the spherical chamber and the conical chamber, the pressure at the wire drawing outlet can always be balanced, which can not only ensure the efficiency of wire drawing, but also improve the quality of wire drawing, and greatly improve the practicality.

[0057] Specifically, the self-adhesive polymer material is epoxy resin or vinyl ester or unsaturated polyester.

[0058] Specifically, the acid glycoside curing agent is one or more of trimellitic anhydride, maleic anhydride, trimellitic anhydride ethylene glycol, and diphenyl sulfone tetracarboxylic dianhydride.

[0059] Specifically, the thermoplastic polymer engineering plastics are one or both of polyamide and polycarbonate polymer materials.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
