Description

Technical Field

[0001] The invention relates to a method for preparing an anti-pollution flashover coating, in particular to a method for preparing an anti-algae anti-pollution flashover coating for coating the surface of an insulating material. Background Art

[0002] With the acceleration of industrial development and the deteriorating environment, power grid equipment is more and more susceptible to pollution flashover accidents, causing large-scale power outages and affecting the safe operation of the power grid. Outdoor pollution flashover prevention is an important task to ensure the safety of the power grid. Long-term practice has proved that coating RTV anti-pollution flashover coating on the insulation materials of the power grid can play an obvious role in preventing pollution flashover.

[0003] However, if the environment is rainy and foggy all year round and the air is humid, even if the RTV anti-pollution flashover coating is applied to the surface of the external insulation materials of many power equipment, large areas of moss and mildew will still grow. These mosses easily absorb moisture and inorganic salts in the air, thus forming a conductive layer on their surface. This will affect the safe and stable operation of the power system, which requires the development of an anti-pollution flashover coating with excellent mildew and moss resistance as soon as possible.

[0004] Therefore, the research purpose of the present invention is to design a method for preparing an anti-algae anti-fouling flashover coating for insulating material surface coating that can produce an anti-fouling flashover coating with excellent anti-mildew and anti-moss effects. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a method for preparing an anti-algae anti-pollution flashover coating for surface coating of insulating materials, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is: A method for preparing an anti-algae anti-fouling flashover coating for surface coating of an insulating material comprises the following specific steps: S1, adding hydroxy-terminated polydimethylsiloxane, white carbon black and coupling agent in proportion into corresponding reaction equipment for stirring and mixing reaction, the reaction temperature is 80-120° C., the reaction time is 2-4 hours, so that the white carbon black and the hydroxy-terminated polydimethylsiloxane are fully combined to form a pre-treated mixture; S2, feeding the nanosilver sol and the pre-treated mixture into a corresponding ultrasonic dispersion device, and ultrasonically dispersing for 30-60 minutes to uniformly disperse the nanosilver in the pre-treated mixture to form a uniform dispersion; S3, feeding the dispersion into a corresponding stirring device, slowly adding a curing agent while stirring, and continuing stirring for 30-60 minutes to allow the curing agent to fully react with the hydroxy-terminated polydimethylsiloxane; S4, add auxiliary agent, stir evenly, filter to remove impurities, and obtain anti-algae anti-fouling flashover coating.

[0007] The particle size of the nano silver sol is 10-50 nm, and the mass fraction is 1%-3% of the total mass of the coating.

[0008] The molecular weight of the terminal hydroxyl polydimethylsiloxane is 5000-20000, the coupling agent is γ-aminopropyltriethoxysilane, the curing agent is an organic tin curing agent, and the auxiliary agent includes a dispersant, a defoaming agent, and a leveling agent.

[0009] The ultrasonic dispersion equipment used in step S2 includes: A material storage barrel is fixedly mounted on a corresponding frame, and a corresponding sealing cover is fixedly mounted on the top of the material storage barrel; The dispersion mechanism comprises at least one dispersion drive pipe rotatably mounted on the bottom side of the cover, a plurality of corresponding dispersion disks are fixedly connected to the dispersion drive pipe in different heights, and the dispersion drive pipe is driven by the corresponding dispersion drive mechanism; The ultrasonic transmission mechanism comprises an ultrasonic transducer fixedly installed in the dispersed drive pipe in a coaxial state, the ultrasonic transducer and the dispersed drive pipe are arranged at a distance, and the inner side wall of the dispersed drive pipe is provided with at least one pumping impeller arranged at a center with a gap between the ultrasonic transducer and the ultrasonic transducer; The material circulation mechanism comprises feed holes evenly arranged on the lower side of the dispersion drive pipe and discharge holes evenly arranged on the upper side of the pumping impeller. After the material enters the storage barrel, the dispersion drive mechanism is started to drive the dispersion drive pipe and the dispersion disk to rotate at a high speed. The pumping impeller rotates at a high speed as the dispersion drive pipe rotates, thereby effectively pumping the material in the dispersion process along the feed holes of the dispersion drive pipe to the discharge holes of the dispersion drive pipe. The stabilizing mechanism is used to form an upward supporting force for the decentralized drive pipe to compensate for the downward thrust formed by the material continuously passing through the decentralized drive pipe.

[0010] The decentralized drive mechanism includes a drive motor fixedly mounted on the cover, a drive bevel gear with an end face inclined upward fixedly connected to the output shaft end of the drive motor, and a driven bevel gear with an end face facing downward fixedly connected to the drive bevel gear and transmission connected to the drive bevel gear is fixedly connected to the decentralized drive pipe; the stabilization mechanism includes a fixed shaft fixedly mounted on a side of the driven bevel gear that is not transmission connected to the drive bevel gear, and an auxiliary bevel gear with an end face facing upward fixedly connected to the fixed shaft for auxiliary support of the driven bevel gear.

[0011] The dispersed drive pipes are in two groups, which are respectively arranged on both sides of the dispersed drive mechanism, and the dispersed disks on the two groups of dispersed drive pipes are respectively arranged in a staggered manner in height.

[0012] A plurality of corresponding material dispersing parts are arranged at the periphery of the dispersing disk, and between two adjacent material dispersing parts, one is arranged upwards and the other is arranged downwards.

[0013] The ultrasonic transducer is connected to an ultrasonic generator fixed on the cover.

[0014] The frame includes a base and a supporting cylinder fixedly connected to the base, the cylinder body of the supporting cylinder is fixedly connected to the base, the piston column of the supporting cylinder is fixedly connected to a corresponding cross beam, and the cross beam is fixedly connected downward to a group of corresponding connecting cylinders; the storage barrel is fixedly connected to the cylinder body of the supporting cylinder through corresponding connecting arms, the sealing cover is fixedly connected to the piston column of the connecting cylinder, and the sealing cover is fixedly connected to the storage barrel by bolt locking.

[0015] The bottom of the storage barrel is externally connected to a discharge pipe equipped with a discharge valve, and the sealing cover is fixedly connected to a corresponding feed pipe.

[0016] Advantages of the present invention: 1) The present invention has excellent antibacterial and anti-algae properties. Since nanosilver has broad-spectrum and high-efficiency antibacterial properties, it can effectively inhibit the growth of algae and bacteria, thereby effectively solving the flashover problem caused by algae growth in a humid environment, thereby significantly improving the safety and stability of the power system.

[0017] 2) The present invention precisely controls the reaction conditions to ensure that the product still has good hydrophobicity and weather resistance after adding the nano silver sol, has sufficient mechanical strength and wear resistance, and can improve its construction performance and storage stability.

[0018] 3) In the ultrasonic dispersion equipment used in step S2 of the present invention, the dispersion mechanism is first improved and designed to design the driving component of the dispersion disk into a tubular dispersion drive pipe. On this basis, the ultrasonic transducer of the ultrasonic transmission mechanism is further fixedly installed in the dispersion drive pipe in a coaxial state, and the ultrasonic transducer and the dispersion drive pipe are arranged at intervals, and a pumping impeller is arranged at a gap with the ultrasonic transducer on the inner side wall of the dispersion drive pipe. After the material enters the storage barrel, the dispersion drive mechanism is started to drive the dispersion drive pipe and the dispersion disk to rotate at high speed, thereby forming a sufficient dispersion processing operation for the material; in this process, the pumping impeller rotates at high speed with the rotation of the dispersion drive pipe, thereby effectively pumping the material in the dispersion process along the feed hole of the dispersion drive pipe to the discharge hole of the dispersion drive pipe, so as to effectively and significantly improve the ultrasonic dispersion processing effect and processing efficiency of the material without affecting the material dispersion operation process.

[0019] Thereby, the nano silver material can be effectively and evenly dispersed in the pre-treated mixture to form a uniform dispersion, thereby effectively ensuring the quality of the product.

[0020] 4) As the material is continuously pumped upward from the feed hole of the decentralized drive pipe to the discharge hole of the decentralized drive pipe, a downward force will be applied to the decentralized drive pipe. As the decentralized operation progresses, the installation and operation stability of the decentralized drive pipe will be damaged with a high probability. To this end, the present invention further fixes a driving bevel gear with an end face inclined upward at the output shaft end of the driving motor, and a driven bevel gear with an end face downwardly disposed and connected to the driving bevel gear is fixed to the decentralized drive pipe; and a corresponding fixed shaft is fixedly disposed on the side of the driven bevel gear that is not connected to the driving bevel gear, and an auxiliary bevel gear with an end face upwardly disposed and used to form auxiliary support for the driven bevel gear is fixed to the fixed shaft. Under the cooperation of the driving bevel gear and the auxiliary bevel gear, an inclined support inclined upward is effectively formed on both sides of the driven bevel gear, thereby realizing upward support for the decentralized drive pipe without affecting the normal drive of the decentralized drive pipe, so as to ensure the installation and operation stability of the decentralized drive pipe, and further ensure the practical effect of the present invention.
