[0002] High-temperature phenolic modified phenolic curing agent is a chemical product with important application value in the industrial field. It is based on phenolic compounds and is prepared by modification reaction with phenolic resin. It can play a curing role in high temperature environment. The curing agent has excellent heat resistance and can withstand high temperatures without affecting its curing effect and product performance. At the same time, it can give the cured material good mechanical strength and chemical stability, enhance the material's impact resistance and corrosion resistance, thereby effectively extending the product's service life. High-temperature phenolic modified phenolic curing agent is produced through a series of processes such as pretreatment of raw materials, chemical reaction, cooling, curing and discharging through a flake machine.
[0003] In the production of traditional high-temperature phenolic modified phenolic curing agents, when the product falls into the flake machine through the overflow port, the overflow port cannot be adjusted in size according to the change in the amount of material, which is prone to overflow failure. If the overflow is not timely, the material will stay in the reactor for too long, which will reduce the product quality, hinder the process flow, and reduce production efficiency, thus having a very adverse impact on the quality and efficiency of the entire production process.

[0013] Preferably, the inner cavity bottom wall of the flow guide box is constructed as a flow guide inclined wall, and the flow guide inclined wall is used to guide the material in the flow guide box to move towards the direction of the discharge port.
[0014] A high-temperature phenolic modified phenolic curing agent production process is carried out using the high-temperature phenolic modified phenolic curing agent production device, and the specific steps are as follows:
[0015] A. Prepare the raw materials according to the basic formula ratio, dehydrate the basic epoxy resin and phenolic resin in advance, sieve the phosphorus flame retardant and pre-disperse it in the solvent for use;
[0016] B. Add pretreated basic epoxy resin, phenolic resin, phosphorus flame retardant, defoamer and antioxidant into the reactor, start the heating program, heat to 80-90°C, add bisphenol A, continue stirring until bisphenol A is dissolved, add 50% of the catalyst to the reaction system, continue to heat to 110°C, react for 1h, add the remaining 50% of the catalyst, continue to heat to 130°C, then keep warm and react until the viscosity reaches 800-1200mPa·s, and after the reaction is completed, cool down;

[0022] 2.

[0023] 3. The support spring fixedly connected between the guide box and the support seat can play a certain supporting and buffering role during the up and down movement of the guide box, which helps to ensure the stability of the movement of the guide box. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] See also Figures 1 to 8 , the present invention provides a technical solution.
[0035] A production device for a high-temperature phenolic modified phenolic curing agent comprises a guide box 1, a feed port 7 is provided at the top of the guide box 1, a sleeve tube 2 is fixedly connected to the top of the guide box 1, the sleeve tube 2 is connected to the inner cavity of the guide box 1 through the feed port 7, and a discharge port 9 is provided on the right side of the guide box 1.
[0036] It also includes a reactor 6. The guide box 1 and the reactor 6 can be connected by relatively moving up and down. The lower end of the reactor 6 has a discharge port. The lower end of the reactor 6 is fixedly connected with a docking pipe 5. The docking pipe 5 is connected with the reactor 6 through the discharge port. The sleeve pipe 2 can be slid up and down on the surface of the docking pipe 5. The conventional adaptive setting is that a bracket for supporting the reactor 6 is installed on the surface of the reactor 6, and a valve body for opening and closing the discharge port is installed at the discharge port at the lower end of the reactor 6.
[0037] The inner wall of the sleeve tube 2 is fixedly connected with a plurality of limit sliders 3 arranged in a circular array, and the surface of the butt tube 5 is provided with a plurality of limit slide grooves 4 for the limit sliders 3 to slide up and down. One limit slider 3 slides up and down in one limit slide groove 4. Through the sliding connection between the sleeve tube 2 and the butt tube 5, when the guide box 1 moves up and down, relative sliding occurs between the sleeve tube 2 and the butt tube 5, which can ensure that the channel of the reaction product remains relatively stable during the process of entering the guide box 1 from the reactor 6 through the butt tube 5, the sleeve tube 2, and the feed port 7.
[0038] Put basic epoxy resin and phenolic resin, phosphorus flame retardant, defoamer and antioxidant into the reactor 6, increase the temperature, add bisphenol A, continue to increase the temperature, add catalyst, continue to increase the temperature, stop increasing the temperature when the temperature reaches 130°C, wait for the reaction, start the cooling water circulation pump after the reaction, drop the temperature to 55°C, wait for discharging, and discharge by opening the discharging port. The reaction product passes through the discharging port, through the butt joint 5, and then through the sleeve 2, and enters the guide box 1 from the feed port 7.
[0039] The reactor 6 may be an existing reactor with integrated heating and cooling, or an existing reactor equipped with an existing external temperature control system. Those skilled in the art may select and install the reactor adaptively according to the techniques known in the art.
[0040] It also includes a steel belt flaker 26, which includes a frame, an endless steel belt, a drive roller, a tensioning device, a water-cooled circulation pipeline, and a material scraper. The surface of the frame is fixedly connected to a guide platform 22, and the lower end of the guide platform 22 is in contact with the endless steel belt. The surface of the frame is fixedly connected to a vertically arranged adjusting baffle 21, and the upper end surface of the adjusting baffle 21 is in the same horizontal plane as the upper end surface of the guide platform 22 and has a continuous and smooth transition.
[0041] A connecting plate 18 is fixedly connected to the lower end of the guide box 1, and a T-shaped slider 20 is fixedly connected to the surface of the adjusting baffle 21. A T-shaped slide groove 19 is provided on the surface of the connecting plate 18 for the adjusting baffle 21 to move up and down. The size of the adjusting baffle 21 is adapted to the width of the discharge port 9, and the adjusting baffle 21 can slide up and down along the wall of the discharge port 9.
[0042] By moving the guide box 1 up and down, the adjusting baffle 21 moves up and down correspondingly with the discharge port 9. The reaction product needs to pass over the adjusting baffle 21 to be moved out of the discharge port 9, that is, an overflow port is formed between the top end wall of the discharge port 9 and the top of the adjusting baffle 21. The size of the overflow port can be changed by moving the guide box 1 up and down. After flowing out of the overflow port, the product slides along the surface of the guide table 22 onto the annular steel belt for transportation and cooling.
[0043] When the reaction product enters the guide box 1, the amount of product is relatively large at the beginning. In order to prevent it from flowing out from the discharge port 9 all at once, the overflow port is kept at a relatively minimum width at the beginning. When the amount of product is too small to exceed the adjusting baffle 21, the guide box 1 starts to move upward, so that the adjusting baffle 21 moves downward relative to the discharge port 9, allowing the product to pass over the adjusting baffle 21 until the top of the adjusting baffle 21 is flush with the lower port wall of the discharge port 9. At this time, the guide box 1 moves up to the maximum height.
[0044] When the guide box 1 moves up and down, it will drive the sleeve pipe 2 to move up and down, causing sliding between the sleeve pipe 2 and the docking pipe 5, so that the limit slider 3 moves up and down along the track of the limit slide groove 4, and at the same time it will also drive the connecting plate 18 to move up and down, so that the T-shaped slider 20 moves up and down along the track of the T-shaped slide groove 19.
[0045] An auxiliary baffle 23 that can move up and down is installed on the surface of the frame. The auxiliary baffle 23 is used to cover the discharge port 9. When the guide box 1 moves upward, the distance between the top end wall of the discharge port 9 and the top of the adjusting baffle 21 will become larger, that is, the width of the overflow port will become larger. By setting the auxiliary baffle 23, the excess part of the upper part after the overflow port becomes larger can be covered. At this time, the product can actually pass through the channel opening formed between the auxiliary baffle 23 and the adjusting baffle 21. The size of the channel opening can be adjusted by moving the auxiliary baffle 23 up and down. On the one hand, it can prevent the overflow port from being easily disturbed by the flow after it becomes larger. On the other hand, it can prevent the thickness of the product from being inconsistent when it passes over the adjusting baffle 21 after the overflow port becomes larger. By adjusting the channel opening, it can be ensured that the thickness of the product when it passes over the adjusting baffle 21 is close to the width of the channel opening.
[0046] A second motor 25 is installed on the surface of the frame, and the output end of the second motor 25 is coaxially fixedly connected with a vertically arranged second screw rod 24. The second screw rod 24 movably penetrates the auxiliary baffle 23, and the second screw rod 24 and the auxiliary baffle 23 are threadedly connected. The second motor 25 is started to drive the second screw rod 24 to rotate. Due to the threaded action between the second screw rod 24 and the auxiliary baffle 23, the auxiliary baffle 23 moves up and down along the axial direction of the second screw rod 24.
[0047] The frame provides an installation basis for other components. The transmission rollers include active rollers and driven rollers, which are installed on the frame. The two ends of the steel belt are respectively wound around the transmission rollers. The active rollers are connected to the motor, and the steel belt is driven by the motor to circulate, providing power for the transportation of materials. The tensioning device is used to adjust the tension of the steel belt. The water-cooling circulation pipeline includes an inlet pipe and a return pipe. The inlet pipe and the return pipe are respectively arranged at both ends of the annular steel belt. The inlet pipe is connected to the water cooling box through a water pump to transport cooling water to the top of the steel belt to cool the material; the return pipe pumps the cooled water back to the water cooling box to realize the recycling of cooling water. The unloading scraper is installed at the discharging end of the steel belt. When the material is cooled and solidified into sheets on the steel belt, the unloading scraper scrapes the sheet material from the steel belt to enter the subsequent processing process.
[0048] It also includes a support seat 12, the top of which is connected to a support plate 10 that can move up and down. The support plate 10 and the guide box 1 are fixedly connected, and the guide box 1 can be moved up and down by moving the support plate 10 up and down.
[0049] The surface of the support seat 12 is provided with a guide slot 11 for the support plate 10 to slide up and down. A vertically arranged first screw rod 13 is rotatably connected in the guide slot 11. The first screw rod 13 movably penetrates the support plate 10, and the first screw rod 13 and the support plate 10 are threadedly connected. By rotating the first screw rod 13, the support plate 10 moves up and down along the track of the guide slot 11 due to the thread action between the first screw rod 13 and the support plate 10.
[0050] A first motor 16 is installed on the surface of the support seat 12, and the output end of the first motor 16 is coaxially fixedly connected to the second bevel gear 15, and the end of the first screw rod 13 is coaxially fixedly connected to the first bevel gear 14, and the first bevel gear 14 and the second bevel gear 15 are meshingly connected. By starting the first motor 16, the second bevel gear 15 is driven to rotate, and the rotation of the second bevel gear 15 drives the first bevel gear 14 to rotate, and the rotation of the first bevel gear 14 drives the first screw rod 13 to rotate.
[0051] A vertically arranged support spring 17 is fixedly connected between the guide box 1 and the support seat 12 .
[0052] The inner cavity bottom wall of the flow guide box 1 is constructed as a flow guide inclined wall 8, and the flow guide inclined wall 8 is used to guide the material in the flow guide box 1 to move toward the direction of the discharge port 9.
[0053] Basic formula proportions by mass: basic epoxy resin: 100 parts, phenolic resin: 30-50 parts, phosphorus-based flame retardant: 10-15 parts, defoaming agent: 0.5-1.5 parts, antioxidant: 0.3-0.8 parts, bisphenol A: 5-10 parts, catalyst: 0.5-1.2 parts.
[0054] Raw material pretreatment: Epoxy resin and phenolic resin need to be dehydrated in advance, vacuum dried, and the moisture content is ≤0.1%; phosphorus flame retardant is sieved to 200 mesh, and then pre-dispersed in a solvent such as acetone for later use.
[0055] Staged temperature control and reaction monitoring: after the initial feeding, the temperature is raised to 80-90°C at a rate of 2°C / min, and bisphenol A is added and stirred for 30 minutes until it dissolves; the catalyst is added twice: 50% of the catalyst is added for the first time, the temperature is raised to 110°C for reaction for 1 hour, and the change of the epoxy value is monitored, with a target value of 0.15-0.25; the remaining catalyst is added, the temperature is raised to 130°C at a rate of 1°C / min, and the reaction is kept warm until the viscosity reaches 800-1200mPa·s.
[0056] Inert gas protection: nitrogen is introduced throughout the process with a flow rate of 0.5-1L / min to avoid oxidation side reactions.
[0057] Gradient cooling: After the reaction is completed, the temperature is lowered to 80°C at a rate of 3°C / min, and the cooling water circulation is started to reduce the temperature to 55°C.
[0058] Online viscosity monitoring: Install an online viscometer to monitor system uniformity in real time, with target viscosity fluctuation ≤5%.
[0059] Gradient cooling: The cooling system of the flaker controls the surface temperature of the steel strip at 20-25°C, the steel strip transport line speed is set at 8-12m / min, and the thickness of the sheet product is controlled at 1-2mm by adjusting the auxiliary baffle 23.
[0060] The specific scheme is as follows: prepare the raw materials by mass according to the basic formula ratio, put the pretreated basic epoxy resin, phenolic resin, phosphorus flame retardant, defoamer, and antioxidant into the reactor 6, start the heating program, add bisphenol A after reaching the target temperature, continue stirring until bisphenol A is completely dissolved, add 50% of the catalyst to the reaction system, continue to heat up, and after reaching the target temperature, react at this temperature for 1 hour. After the reaction is completed, add the remaining 50% of the catalyst, heat up again, and after reaching the target temperature, keep the temperature for reaction. After the reaction is completed, cool down and the temperature drops to Below 55°C, open the valve body at the discharge port at the lower end of the reactor 6 to prepare for discharge. The reaction product passes through the discharge port, passes through the butt joint 5 and the sleeve 2 in sequence, and enters the guide box 1 from the feed port 7 opened at the top of the guide box 1. When the reaction product enters the guide box 1, since the amount of product is large at the beginning, in order to prevent a large amount of outflow from the discharge port 9 at one time, the first motor 16 is started to drive the second bevel gear 15 to rotate, and then the first bevel gear 14 and the first screw rod 13 are rotated. Under the action of the thread, the support plate 10 drives the guide box 1 to move downward, so that the discharge port 9 An overflow port with a relatively minimum width is formed between the top port wall and the top of the regulating baffle 21. The width of the overflow port with the minimum width is controlled at 1-2 mm according to the thickness of the product. As the amount of product decreases, when the amount of product is too small to pass over the regulating baffle 21, the first motor 16 is started in reverse to move the guide box 1 upward, and the regulating baffle 21 moves downward relative to the discharge port 9, so that the product can pass over the regulating baffle 21 and flow out of the overflow port. According to the flow rate, the regulating baffle 21 is continuously moved downward relative to the discharge port 9 until the top of the regulating baffle 21 is flush with the lower port wall of the discharge port 9. When the guide box 1 moves upward to widen the overflow port, the second motor 25 is started to drive the second screw 24 to rotate, and the auxiliary baffle 23 is moved up and down by the thread action, and the distance between the auxiliary baffle 23 and the adjustment baffle 21 is controlled to control the thickness of the sheet product at 1-2mm. After the product flows out of the overflow port, it slides along the surface of the guide table 22 onto the annular steel belt, and the flaking machine starts to work to transport, cool and solidify the product. When the material is cooled and solidified into a sheet on the steel belt, the unloading scraper at the discharge end of the steel belt scrapes the sheet material from the steel belt to enter the subsequent processing process.
