Description

Technical Field

[0001] The invention relates to the technical field of high temperature resistant resin filling, in particular to a high temperature resistant resin filled with nano silicon dioxide. Background Art

[0002] Nano-silicon dioxide is an inorganic chemical material, commonly known as white carbon black. Because it is ultra-fine nano-scale, it has many unique properties, such as optical properties against ultraviolet rays, and can improve the anti-aging, strength and chemical resistance of other materials. It has a wide range of uses. Nano-scale silica is an amorphous white powder, non-toxic, odorless, and pollution-free. The microstructure is spherical, with a flocculent and mesh quasi-particle structure, and is insoluble in water. The characteristics of high-temperature resistant resins are: non-corrosive, resistant to aging, acid and alkali, high and low temperature, insulation, waterproof, and good seismic resistance. It is suitable for various high-temperature industrial repairs, fillings, bonding, etc. The product has strong resistance to mechanical shock and cold and hot shocks, no volatility and low odor, small curing shrinkage, no deformation, and high temperature resistance. The resin is a two-component product. After the two doses are mixed, this product will begin to react, its viscosity will begin to increase, and it will begin to release heat. The more glue mixed together, the faster it reacts and the faster it cures. Please pay attention to the amount of glue used each time. Due to the faster reaction speed, the speed at which it can be used will be shortened. The mixed glue must be used up in a short time. If the proportion of the glue is too large or the stirring is uneven, it may lead to incomplete curing and a decrease in the performance of the glue. High-temperature resistant resin is non-toxic and non-irritating to human skin. If it is accidentally touched, it can be wiped clean with a dry cloth and then washed with clean water. After filling nano-silica into the high-temperature resistant resin, the overall properties of the resin material can be effectively improved.

[0003] For example, the patent document with the announcement number CN 102464845 A discloses a nano-silicon dioxide filled modified PTFE resin. The nano-silicon dioxide filled modified PTFE resin is made of PTFE resin, nano-silicon dioxide, and pigment through low and high speed mixing, compression molding, and free sintering. Polytetrafluoroethylene has excellent electrical insulation, chemical stability, and corrosion resistance, but also has certain disadvantages: poor wear resistance, easy creep, poor compression resistance, etc. The above disadvantages can be improved by adding various high-hardness inorganic powders, but the high-hardness inorganic powders damage the mechanical processing performance of PTFE and cause serious wear on the tool. The present invention provides a nano-silicon dioxide filled modified PTFE resin that can achieve high wear resistance, good compression resistance and creep resistance, and does not affect the mechanical processing performance of the material.

[0004] However, due to the limitation of its own structure, this structure can only carry out simple proportioning and mixing production operations between nano-silica material and high-temperature resistant resin, which easily leads to uneven mixing of the two, resulting in uneven performance of the final resin material, and unable to achieve more sufficient and uniform filling and use operations between nano-silica material and high-temperature resistant resin. At the same time, the equipment can only carry out fixed-rate discharging operations, and cannot perform adaptive filling and proportioning operations according to the actual required ratio between nano-silica material and high-temperature resistant resin, and cannot meet daily use needs. Therefore, it is urgent to design a high-temperature resistant resin filled with nano-silica to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a high-temperature resistant resin filled with nano-silicon dioxide, so as to solve the problem that the existing structure proposed in the above background technology can only carry out simple proportioning and mixing production operations between nano-silicon dioxide materials and high-temperature resistant resins due to the limitations of its own structure, and it is very easy for the two to be mixed unevenly, resulting in the problem of uneven performance of the final resin material, and it is impossible to achieve a more sufficient and uniform filling and use operation between the nano-silicon dioxide material and the high-temperature resistant resin. At the same time, the equipment can often only carry out a fixed-rate discharging operation, and cannot perform adaptive filling and proportioning operations according to the actual required ratio between the nano-silicon dioxide material and the high-temperature resistant resin, and cannot meet the daily use needs.

[0006] To achieve the above purpose, the present invention provides the following technical solution: a high temperature resistant resin filled with nano-silicon dioxide:

[0007] S1: Before mixing the high temperature resistant resin filled with nano-silica, the nano-silica must be surface modified first, because the surface of nano-silica has hydroxyl groups, it is difficult to achieve uniform dispersion by directly adding it to the resin, and it is easy to agglomerate. The surface modification methods include alcohol esterification method, silane coupling agent method, polymer grafting modification method, surfactant method, synchronous modification method and high energy modification method, among which the silane coupling agent method is the most commonly used method, which can make the bonding interface between the polymer and the nano-silica become a chemical bond, significantly improving the reinforcement performance of the nano-silica, including the first storage tank , one end of the first material storage tank is fixedly connected to a center frame, one end of the center frame is fixedly connected to a second material storage tank, an air control frame is arranged at the inner center of the center frame, and contraction frames are arranged at the front and rear ends of the air control frame, an air pump is fixedly connected to the side of the air control frame, and a dustproof grid is arranged at one end of the air pump, an upper conveying pipe is fixedly connected to the top ends of the first material storage tank, the center frame and the second material storage tank, a lower conveying pipe is fixedly connected to the bottom ends of the first material storage tank, the center frame and the second material storage tank, and a central discharge valve seat is fixedly connected to the other side of the first material storage tank;

[0008] S2: After the surface modification of silica is completed, the modified nano silica is evenly dispersed in the high temperature resistant resin matrix through efficient dispersion technology. This process may require the use of equipment such as mixers and ultrasonic dispersers to ensure that the nano particles are stably dispersed in the resin without aggregation. The specific mixing process may be different for different types of high temperature resistant resins, but the overall principle is the same. In this process, the modified nano silica can be evenly mixed with the central extruded high temperature resistant resin by spiral rotation feeding, and preliminary mixing is carried out by mechanical stirring or ultrasonic vibration. Then, the reactor under high temperature and high pressure is used for filling. The reaction is carried out separately to ensure that the nano-silica particles reach the best dispersion state in the resin. After the reaction is completed, the final composite material is obtained through cooling, filtering and other steps. The entire filling and mixing process requires strict control of surface modification and dispersion processes to ensure that the composite material has excellent mechanical properties, thermal stability and other functional characteristics, including a material guide rack, a material guide rack is arranged at the other end of the first storage tank, a loading rack is arranged on the front of the material guide rack, a central material seat is sleeved at the center of the front of the loading rack, and an annular material seat is sleeved on the outer surface of the central material seat, and rotating discharge nozzles are arranged at the upper and lower ends of the front of the annular material seat, and a central discharge nozzle is arranged on the front of the central material seat.

[0009] Preferably, a driving sleeve is fixedly connected to one side of the loading rack, and a driving motor is arranged inside the driving sleeve.

[0014] Preferably, a two-way air seat is provided inside the air control frame, and air control valves are provided at the front and rear ends of the two-way air seat.

[0015] Preferably, the top end of the central discharge valve seat is fixedly connected to an upper discharge valve seat, the bottom end of the central discharge valve seat is fixedly connected to a lower discharge valve seat, a central valve port is arranged inside the central discharge valve seat, and upper and lower valve ports are arranged inside the upper and lower discharge valve seats.

[0016] Preferably, one end of the second material storage tank is fixedly connected to a diverter frame, and diverter valve seats are provided at upper and lower ends of the diverter frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The high temperature resistant resin filled with nano-silicon dioxide can enable the equipment to perform a more uniform mixing and feeding operation between nano-silicon dioxide and the high temperature resistant resin by arranging a first storage tank, a second storage tank, an upper conveying pipe, a lower conveying pipe, a central discharge valve seat, a guide rack, a loading rack, a central material seat, an annular material seat, a rotary discharge nozzle, a central discharge nozzle, a driving sleeve, a driving motor, a driving gear, a rotating shaft, a driving gear ring, a collecting ring seat and a limiting ring groove. In actual use, the staff first injects the high temperature resistant resin raw material into the first storage tank, and the nano-silicon dioxide raw material is injected into the interior of the second storage tank. Then, the high temperature resistant resin is discharged from the central discharge valve seat at the other end of the first storage tank to the guide rack, and the nano-silicon dioxide is discharged into the interior of the guide rack along the upper and lower conveying pipes at the upper and lower ends. Then, the high temperature resistant resin and the nano-silicon dioxide can be guided by the guide rack and enter the interior of the loading rack respectively and evenly. The high temperature resistant resin at the center material seat is directly and evenly extruded from the center discharge nozzle. At this time, the collecting ring seat on the back of the annular material seat can evenly gather the nano-silicon dioxide at the upper and lower ends of the guide frame in an annular shape, and extrude it continuously from the rotating discharge nozzles at the upper and lower ends of the front of the annular material seat. At the same time, the driving motor inside the driving sleeve is started to drive the driving gear at one end to rotate and adjust around the rotating shaft, and the driving gear then adaptively drives the driving gear ring on the side of the annular material seat, so that the annular material seat as a whole can perform a stable limited rotation operation inside the limited ring groove of the loading rack, thereby realizing the rotation of the rotating discharge nozzles at the upper and lower ends around the center discharge nozzle, so that the nano-silicon dioxide can be evenly spirally extruded around the center high temperature resistant resin. The two can evenly fill and load the materials, ensuring that the two can finally be evenly mixed, which reflects the practicality of the equipment design.

[0019] The nano-silicon dioxide-filled high-temperature resistant resin further improves the overall use effect of the equipment by arranging a first storage tank, a central frame, a second storage tank, an air control frame, a shrinkage frame, an air pump, a dust-proof grid frame, an upper conveying pipe, a lower conveying pipe, a central discharge valve seat, a damping rubber ring, a front shrinkage airbag, a rear conveying airbag, a sealing push plug, a two-way air seat, an air control valve, an upper discharge valve seat, a lower discharge valve seat, a central valve port, an upper and lower valve ports, a diverter frame and a diverter valve seat. In daily use, the staff can start the air pump on the side of the air control frame, perform a stable air suction operation from the dust-proof grid frame, and then control the inflation operation to the inside of the shrinkage frame at the front and rear ends of the central frame through the two-way air seat and the air control valve inside the air control frame, so as to realize the adaptive inflation and deflation operation of the front shrinkage airbag and the rear conveying airbag inside the shrinkage frames at the front and rear ends. The front shrinkage airbag and the rear conveying airbag can be inflated and deflated on the inner wall of the shrinkage frame through the damping rubber ring. The telescopic limit operation is performed, and the sealing push plug at one end is used to push the nano silicon dioxide and high temperature resistant resin inside the first storage tank and the second storage tank at this time. Daily, only the two-way air seat and the air control valve on the inner wall of the air control frame need to be controlled to realize the efficient speed control feeding operation of the nano silicon dioxide and the high temperature resistant resin, and the proportioning operation between the nano silicon dioxide and the high temperature resistant resin can be realized. At the same time, the high temperature resistant resin in the lower conveying pipe is directly discharged from the central valve port of the central discharge valve seat. The nano silicon dioxide inside the second storage tank can first be diverted through the diverter frame and the diverter valve seat to enter the upper conveying pipe and the lower conveying pipe at the upper and lower ends, and then evenly discharged from the upper and lower valve ports of the upper discharge valve seat and the lower discharge valve seat at each end, which greatly improves the efficiency of the equipment in controlling and feeding the nano silicon dioxide and the high temperature resistant resin, fully loads the daily production needs of nano silicon dioxide filled with high temperature resistant resin, and reflects the comprehensiveness of the equipment design.
