Description

Technical Field

[0001] This invention relates to a method for applying a two-component, solid-liquid resistant, high-temperature inorganic adhesive, belonging to the field of mechanical joining and bonding technology. Background Technology

[0002] High-temperature resistant inorganic adhesives possess excellent high and low temperature resistance, and offer advantages such as room-temperature curing, low curing shrinkage, excellent durability, and simple preparation processes. They are widely used for bonding materials such as metals, ceramics, and glass, and have particularly promising applications in aircraft thermal protection material bonding. Typical thermal protection materials such as quartz fiber insulation felt and aerogel are often used in aircraft internal thermal protection structures, where they are bonded to the aircraft fuselage using a two-component solid-liquid high-temperature resistant inorganic adhesive. This adhesive consists of two components—liquid resin and powdered / granular curing agent—mixed according to a strict ratio. The allowable mass error for the resin and curing agent is 1%, and the adhesive's pot life after preparation is only 30 minutes, posing challenges for subsequent bonding work. The traditional method involves first weighing the two components according to the ratio, placing them in a ceramic container, stirring and grinding for 3-5 minutes until no obvious solid particles remain, and then pouring the adhesive into a syringe for application. This process requires the adhesive to be handled and transferred in multiple containers, which presents problems such as cumbersome adhesive preparation, large adhesive loss, and inability to control the width and spacing of the adhesive when applying it with syringes.

[0003] To address the aforementioned issues, this invention proposes a rapid adhesive mixing and coating device and process that integrates weighing, stirring, and coating functions. This method allows for rapid coating of adhesive in single, double, or triple lines depending on the coating area, greatly simplifying the operation process, reducing adhesive loss during preparation, effectively shortening adhesive preparation time, achieving precise control of the coating process, and improving bonding quality. Summary of the Invention

[0004] This invention provides a method for applying a solid-liquid two-component high-temperature resistant inorganic adhesive, including a two-component high-temperature resistant inorganic adhesive preparation device integrating weighing, stirring and coating functions, and a rapid coating process. It enables rapid coating of single-line, double-line or triple-line grids and precise control of adhesive width and spacing, effectively shortening adhesive preparation time, reducing adhesive waste, and improving the bonding quality of heat-protective materials.

[0005] The technical solution adopted in this invention is as follows:

[0006] A method for applying a two-component, high-temperature resistant inorganic adhesive involves integrating the mixing, stirring, and application of the two components into a single container. First, the two components are mixed by converting the weight ratio to a volume ratio based on the densities of the resin and hardener components. The amount of each component is determined using the volume markings on the mixing container. Second, the adhesive is stirred using a retractable stirring blade within the same container to thoroughly mix the resin and hardener components. After stirring, the stirring blade is retracted. Finally, the adhesive is applied by pushing the application handle within the same container. An adjustable nozzle is used to achieve single-nozzle, double-nozzle, and triple-nozzle application under different conditions, allowing for precise control of the dispensing distance. The application method includes the following steps:

[0007] Step 1, Prepare the glue mixing device:

[0008] like Figures 1-3 As shown, the glue dispensing device includes a stirring blade conversion handle 1, a glue pushing handle 2, a stirring handle 3, a glue pushing sleeve 4, a stirring sleeve 5, a stirring rotation shaft 6, a stirring blade telescopic rod 7, a dividing plate 8, a compression spring 9, a glue stopper 10, a stirring blade 11, a stirring container 12, a volume scale 13, a glue outlet 14, a glue outlet plug 15, a three-nozzle rod 16, a detachable glue outlet 17, and a double-nozzle rod 18.

[0009] The mixing container 12 is a tubular structure with a closed lower end. A dispensing nozzle 14 is located at the lower end. Before application, the dispensing nozzle 14 is sealed with a nozzle plug 15. A dividing plate 8 is detachably inserted into the mixing container 12, dividing its inner cavity into two non-communicating spaces for loading component A (resin) and component B (curing agent), respectively. Two sets of volume scales 13 are provided on the side wall of the mixing container 12 for measuring the volume of each component. As shown in Figure 4, the dividing plate 8, the mixing container 12, and the nozzle plug 15 constitute a precise and rapid dispensing assembly. The dividing plate 8 is placed in the mixing container 12, and the nozzle plug 15 is inserted into the dispensing nozzle 14. The amount of components A and B added can be directly measured according to the volume scales 13, with an accuracy of ±0.01 cm. 3 .

[0010] The two ends of the stirring blade telescopic rod 7 are fixedly connected to the stirring blade conversion handle 1 and the stirring blade 11, respectively; the upper half of the stirring sleeve 5 is a threaded section with external threads, and the lower half is a smooth rod section, which is fitted onto the stirring blade telescopic rod 7, and the two are slidably engaged. The stirring blade telescopic rod 7 has a protrusion, and the corresponding part of the stirring sleeve 5 has a buckle, which works together to fix the relative position of the stirring blade telescopic rod 7 and the stirring sleeve 5 when it moves downward, and the stirring blade telescopic rod 7 drives the stirring blade 11 to rotate synchronously with the stirring sleeve 5; the stirring rotating shaft 6 is a tubular structure with internal threads, which is fitted onto the threaded section of the stirring sleeve 5, and the two are threadedly engaged; the stirring handle 3 is fixed to the upper end of the stirring rotating shaft 6; the compression spring 9 is fitted onto the lower part of the stirring sleeve 5, with its upper end abutting against the lower end of the stirring rotating shaft 6 and its lower end abutting against the upper end face of the rubber stopper 10; The rubber stopper 10 is a circular rubber stopper with a through hole in the middle. It is fitted tightly to the lower part of the bare rod section of the stirring sleeve 5. The stirring sleeve 5 can slide up and down along the inner hole of the rubber stopper 10. After the stirring blade 11 moves downward with the stirring blade telescopic rod 7, it is located below the rubber stopper 10. After the stirring blade 11 moves upward with the stirring blade telescopic rod 7, it is retracted into the rubber stopper 10. The rubber stopper 10 is placed in the stirring container 12 and is tightly fitted to the inner wall of the stirring container 12. The rubber stopper 10 can slide along the inner wall of the stirring container 12. The pushing rubber sleeve 4 is a hollow tubular structure. Its lower end is fixedly connected to the rubber stopper 10. A strip groove is formed along the length direction on the upper part of the side wall. The pushing rubber sleeve 4 is fitted outside the stirring rotating shaft 6 and the compression spring 9, so that the stirring handle 3 at the upper end of the stirring rotating shaft 6 is placed in the strip groove at the upper part of the pushing rubber sleeve 4. Pushing the stirring handle 3 along the strip groove drives the stirring rotating shaft 6 to move downward. In Figure 5, the stirring blade conversion handle 1, the adhesive push handle 2, the stirring handle 3, the adhesive push sleeve 4, the stirring sleeve 5, the stirring rotation shaft 6, the stirring blade telescopic rod 7, the compression spring 9, the rubber plug 10, and the stirring blade 11 constitute the adhesive stirring assembly.

[0011] Remove the dividing plate 8 to mix components A and B. Place the adhesive mixing assembly into the mixing container 12, positioning the adhesive stopper 10 above the mixed components A and B. Push the mixing blade conversion handle 1 downwards to activate the mixing blade extension rod 7 and the mixing blade 11, causing the mixing blade 11 to extend from the mixing sleeve 5 and the adhesive stopper 10. Push the mixing handle 3 to compress and move the mixing shaft 6 downwards, causing the mixing sleeve 5 to move downwards and rotate, simultaneously rotating the mixing blade 11 to stir the adhesive components A and B in the mixing container 12 and compress the compression spring 9. When the mixing sleeve 5 is compressed to the bottom, release the mixing handle 3. The compression spring 9 will rebound, causing the mixing sleeve 5 to move upwards and rotate, simultaneously moving and rotating the mixing blade 11. Through the up-and-down movement and repeated rotation of the mixing blade 11, the two adhesives A and B in the mixing container 12 are stirred and rapidly blended.

[0012] The double-nozzle rod 18 is a hollow tube with a sleeve in its middle that communicates with its inner cavity for fitting onto the dispensing nozzle 14. Each end of the double-nozzle rod 18 has a detachable nozzle 17, which is a hollow L-shaped structure. One end of the detachable nozzle 17 is a nozzle for dispensing glue, and the other end is a rod-shaped part that is inserted into the end of the double-nozzle rod 18. The dispensing distance is controlled by adjusting the insertion depth, thus achieving double-nozzle dispensing. The triple-nozzle rod 16 has a structure basically the same as the double-nozzle rod 18, except that it has an additional nozzle in the middle for achieving triple-nozzle dispensing. The dispensing distance is adjusted by adjusting the detachable nozzles 17 at both ends. Figure 6 In the above, the glue-applying assembly consists of the glue-applying handle 2, glue-applying sleeve 4, glue stopper 10, three-nozzle rod 16, detachable glue nozzle 17, and double-nozzle rod 18.

[0013] When applying glue, it can dispense glue with a single nozzle, two nozzles, or three nozzles. When dispensing glue with two nozzles or three nozzles, the glue dispensing interval is adjustable.

[0014] Before applying the adhesive, pull the stirring blade conversion handle 1 upwards to move the stirring blade telescopic rod 7 and the stirring blade 11, causing the stirring blade 11 to retract into the stirring sleeve 5 and the adhesive stopper 10. During adhesive application, select the corresponding dispensing nozzle according to the actual coating area and mesh spacing of the part, and adjust the dispensing spacing by moving the detachable nozzle 17. Push the adhesive push handle 2 to move the adhesive push sleeve 4 and the adhesive stopper 10 downwards, squeezing the adhesive out of the dispensing nozzle. After application, use water or industrial alcohol to clean any remaining adhesive from the adhesive application device.

[0015] Step 2: The ambient temperature for preparing the adhesive is controlled within the range of 22℃±3℃, and the humidity is controlled within the range of RH%≤65%.

[0016] Step 3, Prepare the adhesive:

[0017] Step 3.1, calculate the volume V of components A and B. A and V B :

[0018] The weight ratio of components A and B in the preparation process is converted to a volume ratio. The solid-liquid two-component adhesive consists of component A (resin) and component B (curing agent) in a mass ratio of 1:x. The total mass of each preparation is M, and the mass of component A (resin) is M. A The density is ρ A The mass of component B (curing agent) is M. B The density is ρ B The volume of component A (resin) is V. A =M A / ρ A =M*1 / (1+x) / ρ A The volume of component B (curing agent) is V.B =M B / ρ B =M*x / (1+x) / ρ B Where x and ρ A ρ B All are known constants, 1 / (1+x) / ρ A and x / (1+x) / ρ B It is also a fixed constant, therefore it is represented as V A =M*K A V B =M*K B K A =1 / (1+x) / ρ A K B =x / (1+x) / ρ B .

[0019] Based on the target batch mass M, the required volume V of components A and B can be calculated directly and quickly. A and V B This method avoids the tedious process of weighing the A and B components separately in the traditional mixing process, reducing mixing steps and improving mixing efficiency. Applying this method can shorten the mixing process from 8-10 minutes to 2-3 minutes.

[0020] Step 3.2: Place the dividing plate 8 into the mixing container 12, and insert the dispensing nozzle cap 15 into the dispensing nozzle 14. Pour components A and B into the two sides of the mixing container 12 respectively, so that V A and V B Reach the corresponding scale mark position.

[0021] Remove the dividing plate 8 from the mixing container 12 to mix components A and B. Place the adhesive mixing assembly into the mixing container 12, so that the plug 10 is above the mixed components A and B. Push the mixing blade conversion handle 1 downward to drive the mixing blade extension rod 7 and the mixing blade 11, so that the mixing blade 11 extends out from the mixing sleeve 5 and the plug 10.

[0022] Pushing the stirring handle 3 downwards causes the stirring shaft 6 to compress and move downwards, which in turn causes the stirring sleeve 5 to move downwards and rotate. Simultaneously, the stirring blades 11 rotate, stirring components A and B in the mixing container 12 and compressing the compression spring 9. When the stirring shaft 6 reaches the bottom, releasing the stirring handle 3 causes the compression spring 9 to rebound, moving the stirring shaft 6 upwards. This, in turn, causes the stirring sleeve 5 to move upwards and rotate, while simultaneously moving and rotating the stirring blades 11. This process is repeated until components A and B are evenly mixed and no obvious solid particles remain.

[0023] Pull the stirring blade conversion handle 1 upward to drive the stirring blade telescopic rod 7 and the stirring blade 11, so that the stirring blade 11 retracts into the stirring sleeve 5 and the rubber stopper 10.

[0024] Step 4, Apply glue:

[0025] Step 4.1: Remove the nozzle plug 15 from the nozzle 14 position, and select and adjust the appropriate nozzle according to the actual glued part and the width of the glue grid.

[0026] Step 4.2, as follows Figure 7 As shown, the nozzle position is aligned with the corresponding adhesive application position of the heat insulation part, and the push handle 2 is pushed to move the push sleeve 4 and the plug 10 downward to squeeze the adhesive out of the nozzle.

[0027] Step 4.3: After the adhesive is applied, clean the entire adhesive application device with water or industrial alcohol to ensure that there is no residual adhesive on the surface and inside.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This invention can achieve precise proportioning of solid and liquid two-component formulations, increasing the mixing efficiency by 3 to 5 times compared to manual mixing.

[0030] 2. It allows for the integration of adhesive preparation and application within the same enclosed space, reducing resin volatilization during preparation and application, and extending the adhesive's pot life from 30 minutes to 90 minutes.

[0031] 3. The three processes of adhesive mixing, stirring and coating are all completed in the same container, reducing the transfer between the three processes, improving efficiency and avoiding losses during the transfer process. The process is simplified, the work efficiency is increased by 200%, and the adhesive consumption is reduced from 50% to 10%, which greatly improves the utilization rate of adhesive and saves usage costs.

[0032] 4. Enables rapid and precise application of both solid and liquid components, allowing for accurate control of adhesive width, height, and mesh spacing during the application process, effectively improving the bonding quality of thermal protection materials. Attached Figure Description

[0045] Step 1, Prepare the glue mixing device:

[0047] The mixing container 12 is a tubular structure with a closed lower end. A dispensing nozzle 14 is provided at the lower end. Before applying the adhesive, the dispensing nozzle 14 is sealed with a nozzle plug 15. A dividing plate 8 is detachably inserted into the mixing container 12, dividing the inner cavity of the mixing container 12 into two non-communicating spaces for respectively loading component A (resin) and component B (curing agent). Two sets of volume scales 13 are provided on the side wall of the mixing container 12 for measuring the volume of the two components. In Figures 4(a) and 4(b), the dividing plate 8, the mixing container 12, and the nozzle plug 15 constitute a precise and rapid adhesive dispensing assembly.

[0048] Place the dividing plate 8 into the mixing container 12, and insert the dispensing nozzle cap 15 into the dispensing nozzle 14. The amount of components A and B added can be directly measured according to the volume scale 13, with an accuracy of ±0.01 cm. 3 .

[0049] The two ends of the stirring blade telescopic rod 7 are fixedly connected to the stirring blade conversion handle 1 and the stirring blade 11, respectively; the upper half of the stirring sleeve 5 is a threaded section with external threads, and the lower half is a smooth rod section, which is fitted onto the stirring blade telescopic rod 7, and the two are slidably engaged. The stirring blade telescopic rod 7 has a protrusion, and the corresponding part of the stirring sleeve 5 has a buckle, which works together to fix the relative position of the stirring blade telescopic rod 7 and the stirring sleeve 5 when it moves downward, and the stirring blade telescopic rod 7 drives the stirring blade 11 to rotate synchronously with the stirring sleeve 5; the stirring rotating shaft 6 is a tubular structure with internal threads, which is fitted onto the threaded section of the stirring sleeve 5, and the two are threadedly engaged; the stirring handle 3 is fixed to the upper end of the stirring rotating shaft 6; the compression spring 9 is fitted onto the lower part of the stirring sleeve 5, with its upper end abutting against the lower end of the stirring rotating shaft 6 and its lower end abutting against the upper end face of the rubber stopper 10; The rubber stopper 10 is a circular rubber stopper with a through hole in the middle. It is fitted tightly to the lower part of the bare rod section of the stirring sleeve 5. The stirring sleeve 5 can slide up and down along the inner hole of the rubber stopper 10. After the stirring blade 11 moves downward with the stirring blade telescopic rod 7, it is located below the rubber stopper 10. After the stirring blade 11 moves upward with the stirring blade telescopic rod 7, it is retracted into the rubber stopper 10. The rubber stopper 10 is placed in the stirring container 12 and is tightly fitted to the inner wall of the stirring container 12. The rubber stopper 10 can slide along the inner wall of the stirring container 12. The pushing rubber sleeve 4 is a hollow tubular structure. Its lower end is fixedly connected to the rubber stopper 10. A strip groove is formed along the length direction on the upper part of the side wall. The pushing rubber sleeve 4 is fitted outside the stirring rotating shaft 6 and the compression spring 9, so that the stirring handle 3 at the upper end of the stirring rotating shaft 6 is placed in the strip groove at the upper part of the pushing rubber sleeve 4. Pushing the stirring handle 3 along the strip groove drives the stirring rotating shaft 6 to move downward. In Figures 5(a) and 5(b), the stirring blade conversion handle 1, the adhesive push handle 2, the stirring handle 3, the adhesive push sleeve 4, the stirring sleeve 5, the stirring rotation shaft 6, the stirring blade telescopic rod 7, the compression spring 9, the rubber plug 10, and the stirring blade 11 constitute the adhesive stirring assembly.

[0050] Remove the dividing plate 8 to mix components A and B. Place the adhesive mixing assembly into the mixing container 12, positioning the adhesive stopper 10 above the mixed components A and B. Push the mixing blade conversion handle 1 downwards to activate the mixing blade extension rod 7 and the mixing blade 11, causing the mixing blade 11 to extend from the mixing sleeve 5 and the adhesive stopper 10. Pushing the mixing handle 3 compresses and moves the mixing shaft 6 downwards, causing the mixing sleeve 5 to move downwards and rotate clockwise, simultaneously rotating the mixing blade 11 to stir the adhesive components A and B in the mixing container 12 and compressing the compression spring 9. When the mixing sleeve 5 is compressed to the bottom, release the mixing handle 3. The compression spring 9 rebounds, causing the mixing sleeve 5 to move upwards and rotate counterclockwise, simultaneously moving and rotating the mixing blade 11. Through the up-and-down movement and repeated rotation of the mixing blade 11, the two adhesives A and B in the mixing container 12 are stirred and rapidly blended.

[0051] The double-nozzle rod 18 is a hollow tube with a sleeve in its middle that communicates with its inner cavity for fitting onto the dispensing nozzle 14. Each end of the double-nozzle rod 18 has a detachable nozzle 17, which is a hollow L-shaped structure. One end of the detachable nozzle 17 is a nozzle for dispensing glue, and the other end is a rod-shaped part that is inserted into the end of the double-nozzle rod 18. The dispensing distance is controlled by adjusting the insertion depth, thus achieving double-nozzle dispensing. The triple-nozzle rod 16 has a structure basically the same as the double-nozzle rod 18, except that it has an additional nozzle in the middle for achieving triple-nozzle dispensing. The dispensing distance is adjusted by adjusting the detachable nozzles 17 at both ends. Figure 6 In the above, the glue-applying assembly consists of the glue-applying handle 2, glue-applying sleeve 4, glue stopper 10, three-nozzle rod 16, detachable glue nozzle 17, and double-nozzle rod 18.

[0052] When applying glue, it can dispense glue with a single nozzle, two nozzles, or three nozzles. When dispensing glue with two nozzles or three nozzles, the glue dispensing interval is adjustable.

[0053] Before applying the adhesive, pull the stirring blade conversion handle 1 upwards to move the stirring blade telescopic rod 7 and the stirring blade 11, causing the stirring blade 11 to retract into the stirring sleeve 5 and the adhesive stopper 10. During adhesive application, select the corresponding dispensing nozzle according to the actual coating area and mesh spacing of the part, and adjust the dispensing spacing by moving the detachable nozzle 17. Push the adhesive push handle 2 to move the adhesive push sleeve 4 and the adhesive stopper 10 downwards, squeezing the adhesive out of the dispensing nozzle. After application, use water or industrial alcohol to clean any remaining adhesive from the adhesive application device.

[0054] Step 2: Adjust the mixing environment. The ambient temperature should be controlled at 22℃ and the ambient humidity at RH% = 60%.

[0055] Step 3, Prepare the adhesive:

[0056] Step 3.1, calculate the volume V of components A and B. A and V B :

[0057] The weight ratio of the A and B two-component adhesives is converted into a volume ratio during the preparation process.

[0058] V A =M*K A (1)

[0059] V B =M*K B (2)

[0060] —M represents the total mass of the configuration;

[0061] ——ρ A This represents the density of component A (resin).

[0062] ——ρ B This refers to the density of component B (curing agent);

[0063] —The allocation ratio of groups A and B is 1:x;

[0064] ——K A =1 / (1+x) / ρ A ;

[0065] ——K B =x / (1+x) / ρ B .

[0066] In this embodiment, the ratio of components A and B is 1:0.86, and the mass of each batch is 100g. The density ρ of component A (resin) is... A =1.35g / cm^ 3 The density ρ of component B (curing agent) B =2.16g / cm ^3 .

[0067] V is calculated using formulas (1) and (2). A =100*1 / (1+0.86) / 1.35cm ^3 =39.82cm ^3 ,

[0068] V B ==100*0.86 / (1+0.86) / 2.16cm ^3 =21.41cm ^3 .

[0069] Step 3.2: Place the dividing plate 8 into the mixing container 12, and insert the dispensing nozzle cap 15 into the dispensing nozzle 14. Pour components A and B into the two sides of the mixing container 12 respectively, so that V A and V B Reach the corresponding scale mark position.

[0070] Remove the dividing plate 8 from the mixing container 12 to mix components A and B. Place the adhesive mixing assembly into the mixing container 12, so that the plug 10 is above the mixed components A and B. Push the mixing blade conversion handle 1 downward to drive the mixing blade extension rod 7 and the mixing blade 11, so that the mixing blade 11 extends out from the mixing sleeve 5 and the plug 10.

[0071] Pushing the stirring handle 3 downwards compresses and moves the stirring shaft 6 downwards, causing the stirring sleeve 5 to move downwards and rotate clockwise. Simultaneously, the stirring blades 11 rotate, stirring components A and B in the mixing container 12 and compressing the compression spring 9. When the stirring shaft 6 reaches the bottom, releasing the stirring handle 3 causes the compression spring 9 to rebound, moving the stirring shaft 6 upwards. This, in turn, moves the stirring sleeve 5 upwards and rotates counterclockwise, simultaneously causing the stirring blades 11 to move and rotate. This process is repeated until components A and B are evenly mixed and no obvious solid particles remain.

[0072] Pull the stirring blade conversion handle 1 upward to drive the stirring blade telescopic rod 7 and the stirring blade 11, so that the stirring blade 11 retracts into the stirring sleeve 5 and the rubber stopper 10.

[0073] Step 4, Apply glue:

[0074] Step 4.1: Remove the nozzle plug 15 from the nozzle 14, install the three nozzle rod 16 onto the nozzle 14, and adjust the detachable nozzles 17 at both ends of the three nozzle rod 16 to align with the width of the glue application grid.

[0075] Step 4.2, as follows Figure 7 As shown, the nozzle position is aligned with the corresponding adhesive application position of the heat insulation part, and the push handle 2 is pushed to move the push sleeve 4 and the plug 10 downward to squeeze the adhesive out of the nozzle.

[0076] Step 4.3: After the adhesive is applied, clean the entire adhesive application device with industrial alcohol to ensure that there is no residual adhesive on the surface and inside.

[0077] The above-described embodiments are merely illustrative of the implementation methods of the present invention, but should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
