Description

Technical Field

[0001] The invention relates to the manufacture of composite material packaging boxes in the field of aerospace or for special functional purposes, and in particular to a method for manufacturing a glass fiber CVD monene deicing composite material packaging box. Background Art

[0002] In the process of storing products and special precision instruments in the field of aerospace, special packaging boxes need to be manufactured to deal with the impact of possible vibration, temperature and humidity changes on the products or instruments. Therefore, the packaging boxes designed and manufactured have special functions such as buffering and vibration isolation, constant temperature, constant humidity, salt spray protection, and mildew resistance inside the box, which are of great value for storing and transporting such products and instruments. When the packaging box is in a cold or humid environment, ice or water droplets are likely to condense on the outside of the packaging box due to temperature changes. This type of medium has extremely strong permeability, which not only affects the sealing performance of the packaging box, but also causes irreversible damage to the products inside the packaging box, especially to precision products with large temperature and humidity changes.

[0003] At present, most packaging boxes are made of aluminum alloy or composite materials such as glass fiber and carbon fiber. The packaging box and the product fixed interface are made according to the shape and characteristics of the product. The packaging box is pasted with foam and other materials inside the packaging box to achieve the effects of support, shock absorption and collision prevention. For example, the number is: CN202322906677.9 (a transport packaging box), through the fixed connection of one side of the upper box body of the packaging box with the side of the lower box body of the packaging box, the foam is bonded to the inside of the box body of the packaging box to achieve the risk of collision prevention. However, there is no further control of the temperature and humidity environment inside the box. For example, the number is: CN202311633027.X (composite packaging box), by setting an inflation valve and an airtightness detector, and pasting foam on the inner wall of the box, it has the characteristics of light weight, high strength, and good airtightness. It is the mainstream application of packaging boxes at this stage. However, when the packaging box is placed in a cold or humid environment, the packaging box cannot achieve a constant temperature state through heat conduction and other methods. It is necessary to further improve the storage environment, which increases the cost, and when encountering special tasks that cannot provide constant temperature environmental conditions, it will cause damage to precision parts.

[0004] Existing packaging box designs do not have active temperature control. Under special conditions, auxiliary devices such as electric blankets are used to control temperature and de-ice. Traditional metal-based electric heating materials are used, which often face problems such as high power consumption, low flexibility, and resistance to extreme environments. In terms of humidity control function, it is generally achieved by improving the storage environment or building in desiccant. Summary of the invention

[0005] The object of the present invention is to provide a method for manufacturing a glass fiber CVD monene deicing composite material packaging box, which can simultaneously meet the requirements of constant temperature and deicing of composite material packaging boxes in the aerospace field or for special functional purposes.

Other plying methods can be adjusted if they meet the use conditions.

[0018] More preferably, the positive and negative electrodes are made of nickel-copper alloy.

DETAILED DESCRIPTION

[0033] The present invention mainly utilizes the high surface resistance of monene glass fiber cloth (which can be between 1-5000Ω·sq -1 It can be adjusted within a certain range according to the design requirements of the packaging box. It perfectly combines the excellent properties of graphene and glass fiber, showing the flexibility of glass fiber and the electrical and thermal conductivity of graphene. At the same time, the atomic or near-micron-level graphene has no effect on the process design of the fiber. It can be mixed with ordinary glass fiber to make a composite material packaging box, which can achieve a lightweight and high-strength design, and can also achieve the effect of constant temperature and deicing through the Joule heat converted from electric heating.

[0034] The packaging box is generally composed of a box cover and a box bottom. There is a sealing ring between the box cover and the box bottom, and the box cover and the box bottom are pressed and closed with butterfly buckles. This composite material packaging box is formed by RTM molding process using glass fiber treated with CVD monene and epoxy resin. At the same time, the box body is designed with concave and convex rib structures at equal intervals to ensure the strength of the box body. At the same time, the packaging box is equipped with handles or hanging points like conventional packaging boxes for easy transportation. The bottom of the box body is equipped with a forklift slot, and the box cover and the box bottom are equipped with stacking interfaces, waterproof and breathable valves, etc.

[0035] "CVD" stands for chemical vapor deposition, which is a technology that generates solid deposits through chemical reactions of gaseous substances on the solid surface.

[0036] "RTM" stands for resin transfer molding, which is a method of molding composite materials. It mainly involves placing reinforcing materials such as fibers in a mold, pressing the mold together, injecting resin under a certain temperature and pressure, and curing it into shape.

[0037] Using ethylene to provide a constant carbon source, a continuous graphene film with a certain thickness is deposited on the surface of the glass fiber fabric through a high-temperature growth process design. The continuous single-crystal graphene film grown by high-temperature epitaxial growth has a thickness from unit sub-layer to sub-micron layer, which can best reflect the intrinsic excellent properties of graphene and has good electrical and thermal conductivity. It is molded into the packaging box through RTM molding to achieve the effect of heating and deicing.

[0038] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1-5 As shown, the specific steps of the method of the present invention are as follows:

[0040] (1) Glass fiber CVD monene.

[0041] In step (1), the glass fiber CVD monene is prepared by continuously introducing the glass fiber fabric roll (5) as a substrate into a chamber (such as a chamber) at a temperature of 980°C at a uniform speed. Figure 1) to complete the high-temperature deposition growth of graphene, ensuring to the greatest extent possible that different positions on the surface of the fiber fabric experience the same flow field and uniform thermal field environment, thereby greatly improving the uniformity of graphene nucleation and growth.

[0042] The glass fiber fabric roll is made by making the glass fiber fabric into a roll (5) to achieve continuous olefin production on its surface.

[0043] The chamber ( Figure 1 ), is formed by connecting three reaction processing chambers, and the three processing chambers are connected in series through a transmission channel (4). At the same time, a valve unit (6) is arranged between each processing chamber, and a vacuum pump is connected to each reaction processing chamber and the transmission channel.

[0044] The three processing chambers are respectively a glass fiber roll processing chamber (1), a graphene growth processing chamber (2), and a winding and cooling processing chamber (3). Each processing chamber is provided with a retracting roller and a transmission device. The retracting roller is fixed by a fixing device and is made of a quartz tube to withstand the high temperature in the chamber. The transmission device provides tension for the glass fiber roll to prevent the glass fiber fabric from being pushed during the graphene growth process, resulting in uneven surface graphene. The glass fiber roll processing chamber (1) is used to place the glass fiber fabric roll to be processed and is a loading and unloading chamber unit. The graphene growth processing chamber (2) is used to deposit graphene on the spread glass fiber fabric, and the winding and cooling processing chamber (3) is used to collect graphene fiber fabric with good graphene.

[0045] The inner wall of the graphene growth processing chamber (2) is provided with a heat-insulating layer such as graphite felt and heat-insulating cotton, and a plurality of heating modules (10) are arranged inside. At the same time, a temperature control chamber (7) is attached outside the graphene growth processing chamber. The main purpose is to form a uniform temperature field in the graphene growth chamber to avoid heat loss, resulting in uneven heat in the chamber and affecting the growth of graphene on the glass fiber.

[0046] Since the preparation process is carried out under vacuum conditions, the graphene growth chamber needs to be vacuum treated, and the process conditions such as indoor temperature and pressure need to be controlled. The transmission channel also needs to be vacuumed to prevent the outside air from being introduced into the graphene growth processing chamber. Air intake and pressure control equipment are required. The gas used for air intake in the present invention is ethylene. Since the glass fiber roll processing chamber needs to be placed and connected to the graphene glass fiber (9), an external air pump is required to inflate the chamber during the placement process for normal pressure treatment so that the chamber door can be opened for treatment.

[0047] After the glass fiber cloth is coated with olefin, it needs to be rolled up in a winding and cooling treatment chamber (3) for standby use. A cooling module (8) is arranged in the chamber to cool the glass fiber cloth (11) after the coating is completed.

[0048] (2) Plasma spraying electrode.

[0049] The plasma spraying of positive and negative electrodes in step (2) is carried out according to the design of the packaging box preform and the shape required for the layering (such as Figure 3 ) The monene glass fiber cloth (11) produced in step (1) is cut, the direction of the electrode (12) is planned, the path area of ​​the electrode (12) to be sprayed is pre-treated, and the nickel-containing material is sprayed on the monene glass fiber cloth (11) according to the planned path by plasma spraying.

[0050] The ply ( Figure 4 ) is to cut the glass fiber according to the structure and shape of the packaging box, and to lay the layers according to the design requirements. According to the load-bearing characteristics of the packaging box, the present invention distinguishes the radial fiber bundles parallel to the fiber fabric as 0° and the counterclockwise rotation angle as positive, and lays them according to the method of [(0° / 90°)(45° / -45°)], but not limited to this method. The present invention is designed according to quasi-isotropy, and other laying methods can be adjusted to meet the use conditions.

[0051] like Figure 3 As shown, the positive and negative electrodes (12) are obtained by drawing out energized electrodes (12) on the cut monene glass fiber cloth (11), and transmitting electrical energy through the electrodes so that the monene glass fiber cloth (11) generates Joule heat. The present invention uses nickel-copper alloy as the positive and negative electrodes (12), but is not limited to such materials, and other conductive materials can also be used to make electrodes.

[0052] The plasma spraying is a common spraying construction method on the market, which will not be introduced in detail here. The present invention mainly uses a plasma arc driven by direct current as a heat source to heat the nickel-copper alloy to a molten state, and sprays it at a high speed onto the path planned by the monene glass fiber cloth to form two uniform conductive electrodes (12).

[0053] The pretreatment of the electrode path area to be sprayed is to lift the filaments on the glass fiber cloth by needle punching to achieve a roughening effect. Microscopically, when the nickel-copper particles hit this area, they spread, cover and cling to the concave and convex areas of the fiber bundles. After cooling, the nickel-copper alloy and the convex points are interlocked, increasing the bonding strength between the interfaces.

[0054] (3) Production of packaging box preforms.

[0055] In the preparation of the packaging box preform in step (3), the present invention adopts the method of sandwiching the monene glass fiber cloth (11) into the ordinary glass fiber fabric (13), and laying the chopped strand mat at the same time. Therefore, the technology is mature in the composite material industry and will not be described in detail here. The laying ( Figure 3) After the stacking is designed, the multiple layers of fiber fabric are connected into a whole along the thickness direction using warp knitting coils, and then made into a packaging box preform through three-dimensional needle punching, and the extended end of the electrode is reserved for protection.

[0056] (4) RTM molding of packaging boxes.

[0057] In step (4), the packaging box is RTM molded. The resin used in the present invention is epoxy resin. Other vinyl resins, unsaturated polyester resins, and bismaleimide resins can be used as resin materials for composite molding. The epoxy resin used in the present invention belongs to the glycidyl ether type epoxy resin, and the epoxy value is between 0.51 and 0.54. The room temperature viscosity is about 0.27 Pa˙s, and the curing condition is 120℃ / 4h. The lid and bottom of the packaging box are molded separately and then assembled. The lid and bottom are molded in the same way, such as Figure 5 As shown, the mold is provided with a glue injection port (17) on the bottom plate, and a glue overflow port (18) is provided at the rib on the upper part of the mold. The mold is pressurized by bolts (20) and the upper and lower molds are closed to form. During the glue injection process, the extended end of the electrode (12) is placed in the reserved groove of the core mold.

[0058] Further preferably, the molding method and parameters of the packaging box are not unique. The present invention is to put the preform on the core mold (19), fill the glass fiber fabric (13) or the metal insert (14) in the corner area, the reinforcing rib area, and perform trimming after all the stacking is completed, then encapsulate the preform and the core mold (19) into a vacuum bag for vacuuming, send it into an oven, pre-press it at a temperature of 80°C for 2 hours, then place it in the female mold (16), place a silicone rubber strip in the sealing groove of the male mold (15), and tighten the bolts (2 0) close the mold, connect the resin injection machine to the injection port (17), connect the overflow port (18) to the vacuum source, maintain the vacuum degree not less than 0.85MPa, set the temperature of the injection machine to 80-90°C, the resin flow rate to 1-5mL / s, and the injection pressure to 0.5-0.6MPa, complete the injection, close the injection port (17) and the overflow port (18), place the entire mold in a 120°C oven, complete the curing and molding for 4 hours, demould and assemble after natural cooling, and weld the wires at the extended part of the electrode to facilitate power supply.

[0059] Compared with the prior art, the present invention has the following advantages:

[0060] (1) Provide a method for manufacturing a glass fiber CVD monene deicing composite material packaging box.

[0061] (2) Utilize the electrical and thermal conductivity of single crystal or micro-nano graphene and combine it with the flexibility of glass fiber to make heating source materials.

[0062] (3) Taking advantage of the designability of composite materials, the monene glass fiber cloth is mixed into the structure of the packaging box and formed together.

[0063] (4) Taking advantage of the property that ethylene can be converted into graphene at high temperature, the CVD method was applied to non-metallic glass fiber cloth by designing a graphene device.

[0064] (5) Joule heat is introduced without changing the lightweight and high-strength characteristics of the packaging box, achieving the deicing and constant temperature characteristics of the packaging box in extreme environments.

[0065] (6) The raw materials such as glass fiber, epoxy resin, and ethylene are widely available and inexpensive. The RTM molding process enables low-pressure rapid molding of packaging boxes, which is highly practical.

[0066] (7) Through the self-heating characteristics of the packaging box, it can be used as a separate system with strong environmental adaptability. Compared with the metal mesh embedded in the packaging box, it avoids the risk of breakage during molding or transportation, and its practicality is greatly improved.
