Description

Technical Field

[0001] The present application belongs to the technical field of insulators, and in particular relates to high-performance composite silicone rubber insulator materials, insulator components, insulators, and preparation methods. Background Art

[0002] In the field of overhead power lines in the power industry, the performance of insulating materials is of great significance to the safe and stable operation of the lines. Polydimethylsiloxane (PDMS)-based silicone rubber (SR) has low surface energy, hydrophobicity, and good electrical creepage and corrosion resistance after being filled with aluminum hydroxide (ATH). At the same time, the aluminum hydroxide (ATH) filled releases inherent moisture during high-temperature decomposition. The moisture evaporates and absorbs heat during the combustion process, reducing the temperature of the combustion system and slowing the combustion rate. Therefore, polydimethylsiloxane (PDMS)-based silicone rubber filled with aluminum hydroxide (ATH) is widely used as an insulator material in the manufacturing of composite insulator sheds and ceramic / glass insulator coatings.

[0003] However, long-distance overhead power lines need to cross complex areas. In areas where wildfires are frequent, there are high requirements for the flame retardancy of insulator materials to avoid power line failures caused by fire as much as possible. In areas where typhoons are frequent, there are high requirements for the mechanical strength of insulator materials to avoid power line failures caused by insulator structural damage as much as possible. In humid areas, there are high requirements for the hydrophobicity of insulator materials to avoid power line failures caused by insulator flashover as much as possible. Therefore, long-distance overhead power lines have high requirements for the comprehensive performance of insulator materials in terms of flame retardancy, mechanical properties, hydrophobicity, and electrical properties. Silicone rubber insulator materials have the defect of a low limiting oxygen index (LOI), which greatly limits their application as an insulator material in long-distance overhead power lines. After filling with aluminum hydroxide (ATH), although the breakdown voltage, flame retardancy and other properties are improved, the mechanical properties and hydrophobicity are reduced. In addition, the flame retardancy of insulator materials with only aluminum hydroxide (ATH) added is still insufficient.

[0004] Therefore, it is necessary to modify the current silicone rubber insulator material filled with aluminum hydroxide (ATH) to further improve its flame retardant, mechanical, hydrophobic and other properties or multiple properties while meeting the requirements of electrical insulation, so as to improve the comprehensive performance of the silicone rubber insulator material and provide high-performance silicone rubber insulator material to meet the insulation material requirements of long-distance overhead power lines.

[0028] The present application provides high-performance composite silicone rubber insulator materials, insulator components, insulators and preparation methods, which are used to solve the technical problem that the existing technology lacks high-performance silicone rubber insulator materials and is difficult to meet the insulation material requirements of long-distance overhead power lines.

[0029] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0030] In view of the fact that the current silicone rubber insulator material filled with aluminum hydroxide (ATH) has low performance and is difficult to meet the insulation material requirements of long-distance overhead power lines, the present application provides a high-performance composite silicone rubber insulator material. The raw material composition of the provided high-performance composite silicone rubber insulator material includes: addition-type liquid silicone rubber A, addition-type liquid silicone rubber B component, aluminum hydroxide, milled glass fiber and / or graphene nanosheets.

[0031] In a high-performance composite silicone rubber insulator material provided by the present application, the addition-type liquid silicone rubber components A and B are conventional components, including vinyl polydimethylsiloxane base polymer, hydrogen-containing silicone oil, platinum catalyst, acetylene alcohol type silane addition reaction inhibitor and other ingredients, which are catalyzed to undergo silane addition reaction to synthesize the composite silicone rubber insulator material after heating. The introduced aluminum hydroxide is also a common filler for insulators, which can improve the electrical properties and flame retardant properties of the insulator material; and the introduced milled glass fiber is formed by crushing and grinding waste glass fiber, which is in the form of irregularly oriented short fibers, which is conducive to forming a rough surface, and the main component is inorganic non-metallic The material silicon dioxide can play a hydrophobic and flame retardant role in the insulator material, and the introduced graphene nanosheets are two-dimensional graphite nanomaterials with good strength and thermal conductivity, and can play a physical shielding role, thereby playing a role in improving the mechanical strength and flame retardancy of the insulator material. The high-performance composite silicone rubber insulator material provided by the present application can improve the flame retardancy of the insulator material filled with aluminum hydroxide (ATH) by introducing milled glass fibers or graphene nanosheets, and can also improve its hydrophobicity or mechanical strength; More importantly, for the silicone rubber insulator material, the main chain of the silicone rubber insulator material is Si-O-Si The molecular chain has general thermal stability and is easy to melt into a viscous substance at high temperature. After the milled glass fiber and graphene nanosheets are introduced at the same time, the milled glass fiber provides physical support and skeleton, which helps to bind and fix the viscous decomposition products together, and the graphene nanosheets can also provide bottom support. The combination of the two makes it difficult for the viscous decomposition products of silicone rubber to drip, and it is difficult to expose new flammable surfaces of silicone rubber. This makes the silicone rubber insulator material inside the viscous decomposition products of silicone rubber in a high-temperature oxidation and low-oxygen atmosphere, which can promote it to form a layer of ceramic or ceramic-like inorganic / organic hybrid carbon residue with silicon carbide (Si-C) as the main component. Compared with general carbon-based carbon residues, silicon-based composite carbon residues have higher thermal stability, good insulation and excellent barrier properties, and can effectively prevent The heat is prevented from being transferred into the material and the flammable gas is prevented from escaping, thereby achieving the excellent flame retardant properties of the silicone rubber insulator material. In addition, after the milled glass fiber and graphene nanosheets are introduced at the same time, the high strength of the graphene nanosheets improves the mechanical properties such as the tensile strength of the insulator material filled with aluminum hydroxide (ATH). At the same time, due to the high specific surface area of ​​the graphene nanosheets, it is conducive to the dispersion of the short fiber-shaped milled glass fiber between the graphene nanosheets, forming a network structure of graphene nanosheets-milled glass fiber-graphene nanosheets. When the silicone rubber insulator material is subjected to external force, the network structure of graphene nanosheets-milled glass fiber-graphene nanosheets can effectively transmit and disperse stress, preventing the generation and expansion of cracks. The two work together to make the mechanical strength of the silicone rubber insulator material significant.The present application provides a high-performance composite silicone rubber insulator material that, by simultaneously incorporating graphene nanosheets and milled glass fibers, not only enhances the flame retardancy of the aluminum hydroxide (ATH)-filled insulator material, but also synergistically achieves excellent flame retardancy and mechanical properties. This high-performance silicone rubber insulator material exhibits excellent flame retardancy, mechanical properties, and hydrophobicity, meeting the insulation material requirements for long-distance overhead power lines.

[0032] Preferably, the milled glass fiber and graphene nanosheet sizes used in a high-performance composite silicone rubber insulator material provided in this application are as follows: the diameter of the milled glass fiber is 10-15 μm and the length is 50-210 μm, while the diameter of the graphene nanosheet is 2-8 μm.

[0033] Preferably, the amount of raw materials used in a high-performance composite silicone rubber insulator material provided in the present application, calculated in parts by mass, includes: 55 to 65 parts by mass of addition-type liquid silicone rubber A, 2 to 8 parts by mass of addition-type liquid silicone rubber component B, 20 to 40 parts by mass of aluminum hydroxide, 3 to 6 parts by mass of milled glass fiber and / or 3 to 6 parts by mass of graphene nanosheets.

[0034] Correspondingly, the present application also provides a method for preparing a high-performance composite silicone rubber insulator material, which comprises sequentially adding aluminum hydroxide, milled glass fiber, graphene nanosheets, and addition-type liquid silicone rubber B component to addition-type liquid silicone rubber A, stirring and mixing, and obtaining the composite silicone rubber insulator material after degassing.

[0035] Preferably, since the high-performance composite silicone rubber insulator material provided by the present application has excellent flame retardant, mechanical and hydrophobic properties, the present application also provides high-performance glass insulators and ceramic insulators. High-performance glass insulators and ceramic insulators are obtained by applying the above-mentioned high-performance composite silicone rubber insulator material to the surface of the glass insulator / ceramic insulator and curing it into a silicone rubber coating. The glass insulator / ceramic insulator can also be immersed in the above-mentioned high-performance composite silicone rubber insulator material. After taking it out, the surface is cured into a silicone rubber coating to obtain high-performance glass insulators and ceramic insulators.

[0036] Preferably, since the high-performance composite silicone rubber insulator material provided by the present application has excellent flame retardant, mechanical, and hydrophobic properties, the present application also provides sheds and / or sheaths of high-performance insulator components. Furthermore, considering that the milled glass fibers are in the form of irregularly oriented short fibers, which are conducive to forming a rough surface, the present application evenly spreads the milled glass fibers on the shed or sheath mold, pours the high-performance composite silicone rubber insulator material into the shed or sheath mold, and then adds curing to obtain the high-performance insulator component shed or sheath. After curing, the shed or sheath is demolded for use. Since the irregularly oriented short-fiber milled glass fibers are distributed on the surface of the shed or sheath, the roughness is relatively high. This changes the contact mode between water and the shed or sheath surface at a microscopic level, making it easier for water to form a discontinuous contact state on the shed or sheath surface, reducing the contact area between water and the material surface, thereby reducing the wettability of water on the material surface and further improving the hydrophobicity of the shed or sheath.

[0062] The preparation steps of the insulator parts include: pouring the spare composite silicone rubber insulator material into the shed mold, and curing it at 150°C for 30 minutes to obtain the insulator shed.

[0063] Experimental Example 1

[0064] In this experimental example 1, the performance tests of the insulator sheds prepared in Examples 1-5 were carried out. The performance tests included electrical performance tests, flame retardant performance tests, mechanical strength tests, and hydrophobic performance tests.

[0065] Among them, the electrical performance test refers to the insulation material electrical strength test standard IEC60243-1 issued by the International Electrotechnical Commission for breakdown voltage test, the flame retardant performance test refers to the standards ASTMD2863 and ASTM E1354 issued by the American Society for Testing and Materials for limiting oxygen index, maximum average heat release rate, total heat release, total smoke generation and total oxygen consumption tests, the mechanical strength test refers to ASTM D638 issued by the American Society for Testing and Materials for tensile strength and elongation at break tests, and the hydrophobic performance test refers to the standard GB / T 24622-2022 issued by the State Administration for Market Regulation; the test results are shown in Table 1.

[0066] As can be seen from Table 1, compared with the addition type liquid silicone rubber A and B components, the addition of aluminum hydroxide (ATH) can improve the electrical properties and flame retardant properties of the insulator shed, and the further introduction of milled glass fiber can further improve the flame retardant property and the hydrophobic property. The introduction of graphene nanosheets can further improve the flame retardant property and the mechanical properties. At the same time, by comparing the flame retardant and mechanical property tests of Example 1 and Examples 2-3, it can be further seen that when the milled glass fiber and graphene nanosheets are introduced at the same time, the flame retardant and mechanical properties of the insulator shed are significantly improved. This shows that the milled glass fiber provides physical support and skeleton, which helps to bind and fix the viscous decomposition products together, and the graphene nanosheets can be used to bond the viscous decomposition products together. The bottom support provided by the sheet prevents the viscous decomposition products of the silicone rubber from dripping, thereby promoting the formation of a ceramic or ceramic-like inorganic / organic hybrid carbon residue with silicon carbide (Si-C) as the main component. The short-fiber milled glass fibers are dispersed between the graphene nanosheets with a high specific surface area, forming a network structure of graphene nanosheets-milled glass fibers-graphene nanosheets, thereby improving the flame retardancy and mechanical strength of the insulator sheds. A comparison of the hydrophobicity tests of Example 1 and Example 2 shows that in Example 1, the rough surface formed by sprinkling milled glass fibers on the surface of the insulator shed mold makes it easier for water to form a discontinuous contact state on the shed surface, reducing the wettability of water on the shed surface and further improving the hydrophobicity of the shed.
