[0002] Resin usually refers to an organic polymer that has a softening or melting range after being heated, has a tendency to flow under the action of external force when softened, is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin. The relative molecular weight is uncertain but usually high. It is solid, medium solid, pseudo-solid, or sometimes liquid at room temperature. It has a softening or melting temperature range, has a tendency to flow under the action of external force, and often appears in a shell shape when broken. In a broad sense, it refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents. According to the source, it can be divided into natural resins and synthetic resins; according to the different characteristics of their processing behavior, it can be divided into thermoplastic resins and thermosetting resins. Among them, resins that can withstand high temperatures of 300 degrees are also a type of resin.

[0003] In this regard, China's patent application number: CN117186315B discloses a high-temperature resistant photosensitive resin and production equipment, which is prepared by the following components in weight percentage: a high-temperature resistant resin matrix, accounting for 50-70% of the total weight; a photosensitive additive, accounting for 5-20% of the total weight; a reinforcing filler, accounting for 15-30% of the total weight; and a heat-resistant stabilizer, accounting for 1-5% of the total weight. This application uses a high-temperature resistant resin matrix, a photosensitive additive, a heat-resistant stabilizer and an antioxidant to improve the stability and life of the composite material in a high-temperature environment; this application realizes the dual functions of material stirring and mixing and raw material grinding by cooperating with the mounting frame assembly, the transmission mechanism, the material mixing mechanism and the grinding mechanism.

[0004] However, when producing resins that are resistant to high temperatures of 300°, various raw materials need to be stirred, mixed and heated. When stirring and mixing, most of them are stirred directly by a stirring mechanism. When the raw materials are added, the raw materials cannot be dispersed and stirred. At the same time, the raw materials are in a liquid state and will encounter resistance during stirring, resulting in slow efficiency during rotary stirring, and the raw materials cannot be shaken up and down as a whole for stirring. Therefore, it is urgent to improve and perfect the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a resin resistant to high temperatures of 300° and its production equipment, so as to solve the problems raised in the above background technology. However, when producing the resin resistant to high temperatures of 300°, various raw materials need to be stirred, mixed and heated. When stirring and mixing, most of them are stirred directly by a stirring mechanism. When the raw materials are fed and fed, the raw materials cannot be dispersed and stirred. At the same time, the raw materials are in a liquid state and will encounter resistance during stirring, so that the efficiency is slow during rotational stirring, and the raw materials cannot be shaken up and down as a whole for stirring.

[0006] To achieve the above object, the present invention provides the following technical solution: a resin resistant to high temperature of 300° and a production device thereof, comprising the following raw materials: formaldehyde, phenol, boric acid and potassium hydroxide solution, wherein the mass ratio of phenol to potassium hydroxide solution is 100:80-150, and the mass fraction of potassium hydroxide solution is generally 25-30%;

[0007] After the raw materials are stirred evenly, they are heated to 70°C and kept at a constant temperature for 1 hour. After the mixture is kept at a constant temperature, 70-90 parts by mass of formaldehyde are added, and heating and stirring are continued. The temperature is controlled at 90°C and kept for 3-5 hours. Modified phenolic resin is formed through the reaction between aldehyde and phenol.

The reaction between the impregnating agent and the graphite is a combination of physical adsorption and chemical reaction to improve the performance of the graphite material. The impregnating agent penetrates into the micropores of the graphite material and chemically reacts or physically adsorbs with the graphite to form a protective film. This film can prevent or slow down the chemical reaction between the graphite and the surrounding medium, thereby improving the corrosion resistance and high temperature resistance of the graphite.

When the beating block rotates, it will beat the outer surfaces of the first feed frame and the second feed frame, so that the overall beating effect is better, which can speed up the feeding speed of the raw materials. Then, when the rotating shaft continues to rotate, the rotating shaft will drive the third bevel gear to rotate, and then the third bevel gear will mesh with the first bevel gear column and the second bevel gear column respectively, so as to drive the first bevel gear column and the second bevel gear column to rotate, thereby driving the first dispersing blade and the second dispersing blade to rotate. When the first dispersing blade and the second dispersing blade rotate, the raw materials that fall onto the raw materials can be scattered.

Similarly, when the connecting plate and the pressing plate move upward, the rotating plate is not resisted at this time, so that the left side of the rotating plate passes through the gravity of the counterweight block, and the right side of the rotating plate will automatically rise. Therefore, the rotating plate can rotate back and forth under the action of the movable shaft and the counterweight block.

First, raw materials such as formaldehyde, phenol and potassium hydroxide are put in through the first feeding frame 3 and the second feeding frame 4. At this time, the first feeding frame 3 and the second feeding frame 4 can put the raw materials as a whole into the interior of the operating cylinder 1, and then the motor body 5 is started, and the rotating shaft 6 is driven by the motor body 5 to rotate, and then the stabilizing ring 7 and the beating block 8 are driven to rotate through the rotating shaft 6. When the beating block 8 rotates, it will beat the outer surfaces of the first feeding frame 3 and the second feeding frame 4, so that the overall beating effect is better, which can speed up the feeding speed of the raw materials, and then when the rotating shaft 6 continues to rotate, the rotating shaft 6 will drive the third bevel gear 39 to rotate, and then the third bevel gear 39 is respectively connected with the first bevel gear column 10 and the second The bevel gear columns 11 are meshed with each other, thereby driving the first bevel gear column 10 and the second bevel gear column 11 to rotate, thereby driving the first dispersing blade 12 and the second dispersing blade 13 to rotate. When the first dispersing blade 12 and the second dispersing blade 13 rotate, the raw materials that fall on the raw materials can be scattered, and the overall dispersing effect is good, which can make the contact area between the raw materials wider and the overall effect is good. Subsequently, the first bevel gear 15 is driven to rotate through the rotating column 14, and then the second bevel gear 16 is driven to rotate through the first bevel gear 15, and then the connecting rod 17 is driven to rotate through the second bevel gear 16.

At the same time, when the movable ring 20 moves downward, the movable ring 20 will also drive the connecting plate 22 to move downward, so that the connecting plate 22 will drive the pressing plate 23 to move downward. At this time, the connecting plate 22 and the pressing plate 23 will press the right end of the rotating plate 26 to move downward. Similarly, when the connecting plate 22 and the pressing plate 23 move upward, the rotating plate 26 is not interfered, so that the left end of the rotating plate 26 The right side of the rotating plate 26 will automatically rise due to the gravity of the counterweight 29.

[0035] Working principle: When the staff uses the device, firstly, the device is connected to an external power supply to provide power support for the device, and firstly, the raw materials such as formaldehyde, phenol and potassium hydroxide are put through the first feeding frame 3 and the second feeding frame 4. At this time, the first feeding frame 3 and the second feeding frame 4 can put the raw materials as a whole into the inside of the operating cylinder 1, and then the motor body 5 is started, and the rotating shaft 6 is driven to rotate through the motor body 5, and then the stabilizing ring 7 and the slapping block 8 are driven to rotate through the rotating shaft 6. When the slapping block 8 rotates, it will slap the first feeding frame 3 and the second The outer surface of the feed frame 4 has a good overall beating effect, which can speed up the feeding speed of the raw materials. Then, when the rotating shaft 6 continues to rotate, the rotating shaft 6 will drive the third bevel gear 39 to rotate, and then the third bevel gear 39 will mesh with the first bevel gear column 10 and the second bevel gear column 11 respectively, thereby driving the first bevel gear column 10 and the second bevel gear column 11 to rotate, thereby driving the first dispersing blades 12 and the second dispersing blades 13 to rotate. When the first dispersing blades 12 and the second dispersing blades 13 rotate, the raw materials that fall on the raw materials can be scattered. Then, the first bevel gear 15 is driven to rotate by the rotating column 14, and then the second bevel gear 16 is driven to rotate by the first bevel gear 15, and then the connecting rod 17 is driven to rotate by the second bevel gear 16. When the connecting rod 17 rotates, the movable ring 20 on the surface of the connecting rod 17 moves up and down reciprocatingly, and the position of the movable ring 20 can be limited by the limiting ring 18, and the limiting block 21 can limit the moving movable ring 20. At the same time, when the movable ring 20 moves downward, the movable ring 20 will also drive the connecting plate 22 to move downward. The connecting plate 22 drives the pressing plate 23 to move downward, and the connecting plate 22 and the pressing plate 23 press the right end of the rotating plate 26 to move downward. Similarly, when the connecting plate 22 and the pressing plate 23 move upward, the rotating plate 26 is not resisted, so that the left side of the rotating plate 26 passes through the gravity of the counterweight 29, and the right side of the rotating plate 26 automatically rises.

During the rotation, the raw materials can be shaken up and down and stirred through the design of the flow hole 28;

[0036] When the inside of the operating cylinder 1 is mixed and heated, the heat inside the operating cylinder 1 can be conducted through the design of the heat-conducting ring 31, and the overall heat-conducting effect is good. At the same time, water is sent to the inside of the water inlet pipe 37, and then the water enters the inside of the recovery tank 32, and the water inside the recovery tank 32 contacts the heat-conducting ring 31, so that the water can be heated, and the overall heating effect is good. The heat inside the operating cylinder 1 can be recovered as waste heat. At the same time, when the raw materials inside the operating cylinder 1 need to be kept warm later, the hot water after the waste heat recovery can be used to heat the raw materials inside the operating cylinder 1. Insulation, the overall insulation effect is good. At the same time, the outer surface of the waste heat recovery cylinder 30 can be insulated through the design of the insulation ring 33. The water temperature inside the recovery tank 32 can be measured through the design of the measuring column 35 and the temperature sensor 36. The overall measurement effect is good. The discharge pipe 38 is designed to deliver the raw materials inside the operating cylinder 1. At the same time, it is used as an impregnating agent after being delivered and impregnated into graphite.
