Description

Technical Field

[0001] The present invention relates to the technical field of ship composite materials, in particular to a ship composite material plate and a manufacturing method thereof. Background Art

[0002] Traditional ship hulls are mostly made of metal materials, aluminum alloys, titanium alloys and other materials. The manufactured ship hulls have the disadvantages of high specific gravity, high cost, long manufacturing cycle, poor resistance to corrosion and microbial attachment, poor noise reduction effect, poor stealth effect and high maintenance cost. They are generally made of composite materials.

[0003] A patent with the announcement number CN 110328915 A discloses a carbon fiber ship hull and a manufacturing method thereof, which relates to the technical field of ship hulls, and includes an upper panel, the lower surface of which is bonded to a foam core material through an upper bonding layer, and the lower surface of which is bonded to a lower panel through a lower bonding layer. The carbon fiber ship hull and the manufacturing method thereof adopt carbon fiber composite materials, and a foam interlayer is adopted in the middle of the material, which can greatly reduce the overall weight of the ship, and the foam interlayer adopts a porous material core material, which can reduce the weight of the structure and increase the structural rigidity and strength. Since the foam core material adopts a porous core material, it can provide sufficient rigidity and reduce the number of reinforcements.

Even if they are pasted with adhesives, the surface treatment of the adhesive surface is difficult.

However, the artificial spraying method will cause the glue to be laid unevenly when the composite materials are laid again, so that the solidified glue will produce bulges between the composite materials, which will cause the appearance of the composite materials to be uneven when the composite materials are finalized.

[0041] Example 2

[0042] like Fig.11 As shown, a method for manufacturing a composite material plate for a ship comprises the following steps:

[0043] S1. Layer and limit the ship composite materials;

[0044] S2, when the composite material is extruded by the extrusion plastic device, shaping glue is added inside the materials of different layers;

[0045] S3, clamping one end of the composite material with a clamping device, and stacking different layers of composite materials on the surface of the processing table by pulling;

[0046] S4, rolling and shaping the multilayer material by an extrusion device, squeezing out the excess glue between the composite materials while rolling, and cutting the extruded composite materials while extruding;

[0047] S5. Put the cut composite material aside and use a shaping mold to shape the composite material until the glue solidifies naturally, then assemble and polish it.

[0048] Furthermore, if Figure 1 - Figure 3 , Figure 6 , Fig. 9 and Fig.10 As shown, a limiting roller 131 is movably sleeved on the inner wall surface of the second support frame 13, which is respectively wound around the outer surfaces of the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143; a glue filling machine 132 is arranged on the outer surface of the second support frame 13; a glue guide tube 133 is fixedly connected to the output end of the glue filling machine 132; a glue spraying tube 134 is fixedly connected to one end of the glue guide tube 133, which is slidably attached to the outer surface of the top of the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143; a scraper strip 135 is fixedly connected to the bottom surface of the glue spraying tube 134.

[0049] When the polymer-based composite layer 14 slides on the surface of the limiting roller 131, the glue filling machine 132 is used to inject glue into the inside of the glue guide tube 133, and the glue spraying tube 134 on one end of the glue guide tube 133 is used to spray the glue onto the surface of the polymer-based composite layer 14, and the scraper 135 on the bottom surface of the glue spraying tube 134 is used to smooth the excess glue on the top surface of the polymer-based composite layer 14, so that the glue can be evenly laid on the surface of the polymer-based composite layer 14; to avoid the problem that the glue is not laid evenly when the composite material is laid again, so that the solidified glue will produce bulges between the polymer-based composite layers 14, which will cause the appearance of the polymer-based composite layer 14 to be defective and uneven when the polymer-based composite layer 14 is finalized again.

[0050] Further, Figure 1 - Figure 4 , Figure 6 , Figure 8 - Fig.10The extrusion plastic device includes an extrusion plastic platform 11 and a support frame 12 detachably mounted on the edge positions of both sides of the extrusion plastic platform 11, a support frame 2 13 arranged on the edge position of one side of the extrusion plastic platform 11, and a support frame 15 movably sleeved on the inner wall surface of the extrusion plastic platform 11. A hydraulic rod 2 122 is fixedly mounted on the top inner wall surface of the support frame 12, and a downward pressing closing plate 124 movably attached to the outer surface of the polymer-based composite layer 14 is fixedly connected to the output end of the hydraulic rod 2 122. A hydraulic pump 126 is fixedly mounted on the bottom inner wall surface of the extrusion plastic platform 11, and a top pressing plate 125 movably attached to the bottom outer surface of the waterproof resin layer 143 is fixedly connected to the output end of the hydraulic pump 126. The edge positions of both sides of the downward pressing closing plate 124 are provided with movable adhesives on the polymer-based composite layer 143. A cutting knife 127 is provided on the outer surface of the composite layer 14, and a limiting roller 131 is movably sleeved on the inner wall surface of the supporting frame 13, which is respectively wound around the outer surfaces of the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143. A glue filling machine 132 is provided on the outer surface of the supporting frame 13, and a glue guide tube 133 is fixedly connected to the output end of the glue filling machine 132. A glue spraying tube 134 is fixedly connected to one end of the glue spraying tube 133, which is slidably attached to the outer surface of the top of the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143. A scraper 135 is fixedly connected to the bottom surface of the glue spraying tube 134, and the outer surface of the supporting frame 13 is movably overlapped on the outer surface of the polymer-based composite layer 14.

[0051] When the polymer-based composite layer 14 after laying the glue moves to the bottom surface of the downward pressing closing plate 124, the downward pressing closing plate 124 is pressed down by the hydraulic rod 2 122 on the outer surface of the support frame 12, and the hydraulic pump 126 pushes and squeezes the top pressure plate 125 upward, so that the downward pressing closing plate 124 and the top pressure plate 125 are attached to the upper and lower surfaces of the polymer-based composite layer 14, and then the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143 are squeezed together, and as the downward pressing closing plate 124 and the top pressure plate 125 are squeezed at the same time, The polymer-based composite layer 14 is extruded and cut off in cooperation with the cutting knife 127 on the outer surface of the pressing closing plate 124. In the process of extrusion, the glue inside the polymer-based composite layer 14 is completely penetrated into the internal gaps of the polymer-based composite layer 14, thereby increasing the adhesion and adsorption effects between the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143. Extrusion is used to reduce the residual bubbles inside the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143, and at the same time, the excess glue is squeezed out.

[0052] Furthermore, if Figure 1 and Figure 8 As shown, strip grooves are provided on the two side surfaces of the extrusion plastic platform 11 and at the top edge position, a motor 111 is fixedly installed on the two side surfaces of the extrusion plastic platform 11 and at the edge position of one side, a drainage block 1111 is provided on the one side surface of the extrusion plastic platform 11, and a limiting block 112 is fixedly connected to the two side surfaces of the extrusion plastic platform 11 and at the edge position of the other side, a threaded rod 113 movably sleeved on the inner wall of the limiting block 112 is fixedly connected to the output end of the motor 111, a limiting roller 114 slidably overlapped on the inner wall of the strip groove is threadedly sleeved on the outer surface of the threaded rod 113, a sleeve 115 is fixedly connected to the outer surface of the other end of the limiting roller 114, a limiting plate 116 is fixedly connected to the inner wall surfaces of both sides of the sleeve 115, a hydraulic rod 117 is fixedly installed on the upper and lower inner wall surfaces of the sleeve 115, a lower pressing block 118 is fixedly connected to the output end of the hydraulic rod 117, and one end of the lower pressing block 118 The surfaces are respectively connected with a conical extrusion strip 119 and an arcuate extrusion strip 1110, and the inner wall surfaces of the conical extrusion strip 119 and the arcuate extrusion strip 1110 are movably attached to the outer surface of the polymer-based composite layer 14, a soft block a1 is fixedly connected to the bottom surface of the conical extrusion strip 119, a limiting plate a2 is fixedly connected to the outer surface of the soft block a1, a hydraulic damping rod a3 is fixedly connected to the bottom surface of the limiting plate a2, and a movable damping rod a3 is fixedly connected to one end of the hydraulic damping rod a3. A lower pressing plate a4 is overlapped on the bottom surface of the conical extrusion strip 119, and an anti-slip layer a5 is arranged on the bottom surface of the lower pressing plate a4. A limiting rod 123 is movably sleeved on the top surface of the support frame 12 and located on both side edge positions of the hydraulic rod 2 122. The other end of the limiting rod 123 is fixedly connected to the top surface of the lower pressing closing plate 124. A protective cover 121 wrapped around the top surface of the hydraulic rod 2 122 and the limiting rod 123 is fixedly installed on the top surface of the support frame 12.

[0053] The polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143 are overlapped on the inner wall of the arc-shaped extrusion strip 1110 at different heights, respectively, and the hydraulic rod 117 on the inner wall of the casing 115 is used to press the pressing block 118 downward, and the surface of the polymer-based composite layer 14 is squeezed into the inner wall of the arc-shaped extrusion strip 1110. The grooves on the surfaces of the arc-shaped extrusion strip 1110 and the conical extrusion strip 119 are used to deform the polymer-based composite layer 14 when it is extruded, thereby increasing the friction and pulling force between the polymer-based composite layer 14 and the surface of the conical extrusion strip 119. The lower pressing plate a4 on the upper surface is attached to the surface of the polymer-based composite layer 14, and the anti-skid layer a5 on the bottom surface of the lower pressing plate a4 is used to increase the friction and anti-skid force between the surface of the polymer-based composite layer 14, so that the polymer-based composite layer 14 can be firmly positioned on the inner wall surface of the arc-shaped extrusion strip 1110; it avoids the situation that when the traditional polymer-based composite layer 14 is positioned and fixed, the positioning device can only position the edge positions of the two sides of the cloth, and the center position of the polymer-based composite layer 14 cannot be effectively positioned, so that the polymer-based composite layer 14 will generate a certain pulling force when it is pulled, thereby causing the polymer-based composite layer 14 to fall off when it is pulled again.

[0054] Working principle: The one end surfaces of the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143 are overlapped on the inner wall surfaces of the arc-shaped extrusion strips 1110 at different heights respectively, and the hydraulic rod 117 on the inner wall surface of the casing 115 is used to press down the lower pressing block 118, and the surface of the polymer-based composite layer 14 is squeezed into the inner wall surface of the arc-shaped extrusion strip 1110, and the grooves on the surfaces of the arc-shaped extrusion strip 1110 and the conical extrusion strip 119 are used to deform the polymer-based composite layer 14 when it is extruded, thereby increasing the friction and pulling force between the polymer-based composite layer 14 and the surface, and the lower pressing plate a4 on the bottom surface of the conical extrusion strip 119 is fitted on the surface of the polymer-based composite layer 14, and the anti-skid layer a5 on the bottom surface of the lower pressing plate a4 is used to increase the friction and anti-skid force between the polymer-based composite layer 14 and the surface, so that the polymer-based composite layer 14 can be firmly positioned on the arc. The effect on the inner wall surface of the shaped extrusion strip 1110 is achieved; at the same time, the motor 111 is used to rotate the threaded rod 113, so that the limiting roller 114 is threadedly slid on the surface of the threaded rod 113, and then the limiting roller 114 is driven to slide to one side on the surface of the motor 111, so as to pull and move the polymer-based composite layer 14, and at the same time, the 1111 on the surface of one side of the extrusion plastic platform 11 is used to limit the position of the polymer-based composite layer 14; when the polymer-based composite layer 14 slides on the surface of the limiting roller 131, the glue filling machine 132 is used to infuse glue into the inside of the glue guide tube 133, and at the same time, the glue spraying tube 134 on one end of the glue guide tube 133 is used to spray glue onto the surface of the polymer-based composite layer 14, and at the same time, the scraper 135 on the bottom surface of the glue spraying tube 134 is used to smooth the excess glue on the top surface of the polymer-based composite layer 14, so that the glue can be evenly laid on the surface of the polymer-based composite layer 14;When the polymer-based composite layer 14 after laying the glue moves to the bottom surface of the downward pressing closing plate 124, the downward pressing closing plate 124 is pressed down by the hydraulic rod 2 122 on the outer surface of the support frame 12, and the hydraulic pump 126 pushes and squeezes the top pressure plate 125 upward, so that the downward pressing closing plate 124 and the top pressure plate 125 are attached to the upper and lower surfaces of the polymer-based composite layer 14, and the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143 are squeezed together, and the downward pressing closing plate 124 and the top pressure plate 125 are squeezed at the same time, and the cutting knife 127 on the outer surface of the downward pressing closing plate 124 is cooperated. The polymer-based composite layer 14 is extruded and cut, and during the extrusion process, the glue inside the polymer-based composite layer 14 is completely infiltrated into the gap inside the polymer-based composite layer 14, so as to increase the adhesion and adsorption effect between the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143, and the bubble residue inside the polymer-based composite layer 14, the fiber-reinforced composite layer 141, the metal-based composite layer 142 and the waterproof resin layer 143 is reduced by extrusion, and the excess glue is squeezed out at the same time; the cut polymer-based composite layer 14 is placed in a shaping mold for shaping, and after the glue is naturally solidified, the assembly and polishing treatment are performed. ;
