Description

Technical Field

[0001] This invention belongs to the field of power equipment cleaning technology, and relates to a silicone rubber insulator cleaning agent, and more particularly to an environmentally friendly silicone rubber insulator cleaning, repair and protection agent, its preparation method and application. Background Technology

[0002] Silicone rubber insulators, as important external insulation components in power transmission and transformation systems, are widely used in outdoor substations, converter stations, and transmission lines. These insulators are exposed to the natural environment for extended periods, making them susceptible to various pollutants such as coastal salt spray, industrial dust, acidic and alkaline pollutants, and biological deposits in high-humidity environments. The adhesion of pollutants to the surface of silicone rubber insulators involves not only physical adsorption processes such as van der Waals forces, electrostatic adsorption, and capillary action, but also chemical bonding with active groups formed on the silicone rubber surface after aging. This results in a complex and firmly adhered contamination layer structure, making cleaning quite difficult.

[0003] Current maintenance methods for silicone rubber insulators mainly include manual wiping, rinsing with water, and treatment with traditional cleaning agents. Manual wiping and rinsing with water are inefficient, labor-intensive, and insufficient in removing stubborn dirt. Although traditional cleaning agents can remove surface contaminants to some extent, some cleaning agents have problems such as high volatile organic compound content, insufficient environmental friendliness, poor compatibility with silicone rubber substrates, and unstable recovery of the surface's hydrophobic properties after cleaning.

[0004] Furthermore, existing treatment methods primarily focus on cleaning, rarely considering the surface repair and recontamination protection of silicone rubber insulators after cleaning. During long-term operation, silicone rubber insulators may develop microscopic defects, decreased hydrophobicity, and an increased risk of re-contamination. If only surface contamination is removed without improving the microscopic condition and protective capabilities of the cleaned surface, the maintenance effect will be limited in duration and may still affect the long-term operational reliability of the insulators. Summary of the Invention

[0005] This invention provides an environmentally friendly cleaning, repair, and protective agent for silicone rubber insulators, its preparation method, and its application. It effectively solves the problems existing in the cleaning and maintenance of silicone rubber insulators, such as high VOC content of cleaning agents, insufficient environmental friendliness, limited ability to remove complex dirt, insufficient compatibility with silicone rubber substrates, unstable recovery of surface hydrophobic properties after cleaning, insufficient resistance to re-contamination, and insufficient sustainability of surface protection effect after cleaning and repair under outdoor ultraviolet and humid heat environments.

[0011] Further, the dispersion stabilization treatment method is as follows: the functional particles are added to a mixed solvent of water and glycerol containing a polymeric dispersion stabilizer, dispersed under ultrasonic conditions of 300-500W for 10-20 min, and then dispersed under high shear at 8000-12000 r / min for 10-20 min to obtain a pre-dispersion of the functional particles with dispersion stabilization; the polymeric dispersion stabilizer is one or more of polyethylene glycol, polyvinylpyrrolidone, and sodium polyacrylate; the mass ratio of the functional particles, the polymeric dispersion stabilizer and the mixed solvent of water and glycerol is 1:0.05-0.2:5-20.

Thus, it achieves green, efficient, and long-lasting integrated maintenance of silicone rubber insulators through cleaning, repair, and protection. Detailed Implementation

[0017] The present invention will be further described in detail below through specific embodiments, but it should not be construed as limiting the scope of the subject matter of the present invention to the following embodiments. All technologies implemented based on the above content of the present invention fall within the scope of the present invention.

[0018] Unless otherwise specified, the experimental methods used in the following examples are conventional methods, and the reagents, methods and equipment used are conventional reagents, methods and equipment in this technical field.

[0019] This invention provides an environmentally friendly silicone rubber insulator cleaning, repair and protective agent, comprising the following components by mass percentage: 90-96% base solvent, 1-3% cleaning agent, 0.5-2% repair agent, 0.5-2% surface protective agent, and 0.1-0.5% functional additive, wherein the sum of the mass percentages of each component is 100%.

[0020] In some embodiments, the base solvent is a mixed solvent system formed by glycerol and / or glycerol oligomers and water. Preferably, the volume ratio of glycerol and / or glycerol oligomers to water is 1:3 to 5, so that glycerol and / or glycerol oligomers exist in the base solvent in a low concentration. This base solvent can reduce the risk of volatile organic compound release and improve the compatibility of the treatment agent with the silicone rubber substrate.

[0021] The cleaning agents include fluorinated cleaning components and silicone cleaning components.

[0022] In some embodiments, the fluorinated cleaning component is one or more of short-chain fluorocarbon surfactants, fluorinated polyether surfactants, and perfluorobutyl sulfonate surfactants, used to reduce the interfacial tension between the contaminant layer and the silicone rubber surface, enhancing the wetting, penetration, and peeling capabilities of the contaminant layer. The silicone cleaning component is one or more of polyether-modified polydimethylsiloxane, trisiloxane surfactants, and siloxane-polyether copolymers, used to improve the compatibility between the cleaning, repairing, and protective agent and the silicone rubber substrate, and to provide conditions for the uniform action of the repairing agent and the surface protective agent on the silicone rubber surface. Preferably, the mass ratio of the fluorinated cleaning component to the silicone cleaning component is 1:0.5~3, and the two work synergistically to give the cleaning, repairing, and protective agent both low interfacial tension and good silicone rubber surface spreading compatibility, thereby improving the penetration and peeling effect on the composite contaminant layer.

[0023] The repair agent is one or more of the following: silane coupling agent, siloxane repair component, and polysiloxane repair component; In some embodiments, the silane coupling agent is one or more of γ-aminopropyltriethoxysilane, γ-glycidoxypropyltrimethoxysilane, methyltrimethoxysilane, and vinyltriethoxysilane. The siloxane-based repair component is one or more of oligomethylsiloxane and hydroxyl silicone oil. The polysiloxane-based repair component is one or more of hydroxyl-terminated polydimethylsiloxane and amino-modified polysiloxane. The repair agent can form a low surface energy repair layer on the surface of the cleaned silicone rubber insulator, improving surface micro-defects caused by aging, dirt adhesion, or the cleaning process, and promoting the recovery of the hydrophobic properties of the silicone rubber insulator surface; simultaneously, the silane coupling agent can undergo adsorption, condensation, or coupling with the functional particles in the surface protective agent, improving the adhesion stability of the functional particles on the silicone rubber surface.

[0024] The surface protective agent is one or more functional particles selected from SiO2, TiO2, and Al2O3. It enhances the protective effect of the surface after cleaning and repair, reducing the likelihood of re-adhesion of contaminants. Specifically, SiO2 improves surface micro- and nano-roughness and resistance to re-contamination, TiO2 enhances the surface's photo-assisted degradation ability against organic contaminants, and Al2O3 improves the wear resistance and structural stability of the protective layer. The combination of these three components forms a composite protective layer on the surface of silicone rubber insulators, providing hydrophobic recovery, resistance to re-contamination, and weather protection.

[0025] Preferably, the surface protectant is two or three of the functional particles selected from SiO2, TiO2, and Al2O3. When the surface protectant includes the three functional particles SiO2, TiO2, and Al2O3, the mass ratio of SiO2, TiO2, and Al2O3 is 1~2:1~2:0.5~1.5.

[0026] In some implementations, the particle size of the functional particles is 20 nm to 200 nm.

[0027] In some embodiments, the functional particles undergo dispersion and stabilization treatment before the preparation of the silicone rubber insulator cleaning, repair, and protective agent. This dispersion and stabilization treatment involves surface coating, adsorption, or composite dispersion of the functional particles using a cleaning agent, repair agent, and / or polymeric dispersion stabilizer.

[0028] Preferably, the dispersion stabilization treatment method is as follows: Functional particles are added to a mixed solvent of water and glycerol containing a polymeric dispersion stabilizer, and dispersed under ultrasonic conditions of 300-500W for 10-20 min, followed by high-shear dispersion at 8000-12000 r / min for 10-20 min (allowing the polymeric dispersion stabilizer to be adsorbed or coated onto the surface of the functional particles), resulting in a pre-dispersion of functional particles with stable dispersion. The polymeric dispersion stabilizer is one or more of polyethylene glycol, polyvinylpyrrolidone, and sodium polyacrylate. Preferably, the mass ratio of functional particles, polymeric dispersion stabilizer, and the mixed solvent of water and glycerol is 1:0.05-0.2:5-20. The mixed solvent of water and glycerol is considered the base solvent, and its amount is included in the mass percentage of the base solvent.

[0029] Functional additives include pH adjusters and dispersants.

[0030] In some embodiments, the pH adjuster is one or more of citric acid, sodium citrate, sodium dihydrogen phosphate, disodium hydrogen phosphate, and triethanolamine, used to adjust the pH of the system to 6.5-7.5 to reduce adverse effects on the silicone rubber substrate. The dispersing stabilizer is one or more of polyethylene glycol, polyvinylpyrrolidone, and sodium polyacrylate, used to improve the dispersion uniformity of functional particles in the system and reduce the tendency of sedimentation and agglomeration during storage.

[0031] In some embodiments, the functional additives further include weather-resistant synergists, which are one or more of water-based hindered amine light stabilizers and water-based ultraviolet absorbers, used to improve the UV aging resistance and long-term protection capability of the silicone rubber insulator surface after cleaning and repair. The water-based hindered amine light stabilizer is one or more of piperidine-based hindered amine light stabilizers and triazine-based hindered amine light stabilizers; the water-based ultraviolet absorber can be selected from one or more of benzophenone-based ultraviolet absorbers and benzotriazole-based ultraviolet absorbers.

[0032] The preparation method of the above-mentioned environmentally friendly silicone rubber insulator cleaning, repair and protective agent includes the following steps: Step 1: Add the raw materials of the base solvent to the mixing tank and stir at 300-500 r / min for 10-15 min at 25-35℃ to form a uniform and transparent base solvent.

[0033] Step 2: Add the cleaning agent raw materials to the base solvent and stir at 500-800 r / min for 30-40 min at 30-40℃ to ensure uniform dispersion of the fluorinated cleaning component and the silicone cleaning component in the base solvent, thus obtaining a pre-dispersion cleaning solution. The fluorinated cleaning component reduces the interfacial tension of the system, while the silicone cleaning component further improves the spreading compatibility of the system on the silicone rubber surface, giving the resulting silicone rubber insulator cleaning, repair, and protective agent good wetting and penetration capabilities.

[0034] Step 3: Add the raw materials of the repair agent to the pre-dispersion cleaning solution, and continue stirring at 30~40℃ for 20~30 minutes to obtain the cleaning and repair mixture.

[0035] Step 4: Add the surface protective agent that has undergone dispersion stabilization treatment to the cleaning and repair mixture, and perform composite dispersion by combining ultrasonic dispersion and high shear dispersion. The ultrasonic power is 300~500W, the high shear speed is 10000~15000r / min, the dispersion time is 20~30min, and the dispersion temperature does not exceed 40℃. This allows the functional particles to be evenly distributed in the system under the action of the repair agent, thereby forming a continuous or semi-continuous composite protective structure on the surface of the silicone rubber insulator.

[0036] Step 5: Add functional additives and adjust the pH of the system to 6.5~7.5. Continue stirring at 500~800 r / min for 20~30 min to complete the homogenization process and obtain the silicone rubber insulator cleaning, repair and protection agent.
