Description

Technical Field

[0001] The invention belongs to the technical field of bird repelling, and in particular relates to a controllable shedding type bird repelling material, a preparation method and an application thereof. Technical Background With the rapid development of my country's power industry, the coverage area of ​​the power grid has gradually expanded. At the same time, with the continuous strengthening of water and soil environmental protection, the number of birds has increased year by year, and the scope of their activities has also gradually expanded, which inevitably caused great harm to overhead transmission lines. These hazards are collectively referred to as bird damage accidents. According to statistics from relevant departments, the impact of bird activities on transmission line failures is second only to lightning strikes and external force damage. Bird damage is increasingly threatening the normal operation of the national power grid and has caused a severe situation. Therefore, taking certain measures to reduce bird damage failures has become an important task at present.

[0003] Birds generally like to build nests in high places, such as the top of power line towers, because it is convenient for them to enter and exit the nests. Birds nesting on high-voltage line towers poses a threat to the safety of the power grid; bird excrement can easily cause short circuits, and when excrement accumulates on insulators for a long time, it will reduce the insulation and cause power accidents; large wading birds have a long wingspan and are prone to short circuits between lines when entering and exiting the nests; bird nesting materials, such as branches and hay, will be conductive materials when the weather is humid. In addition, if the nesting materials accidentally fall, it is easy to cause power accidents.

[0004] Some common bird repellent methods include installing bird repellent devices on power equipment or spraying and applying bird repellents. However, existing bird repellents need to be installed during power outages, which affects electricity consumption in production and life. The construction and installation of bird repellents affect the symmetry of pole tower hardware, generate external stress, and reduce the mechanical life of the pole tower. At the same time, the construction interface will accelerate the corrosion of the facilities. The bird repellent is mechanically connected to the pole tower. Even if it is firmly installed, it is still possible to be scraped off or damaged in bad weather such as strong winds, and subsequent secondary installation and maintenance are more difficult. Some bird repellents can produce good results at the beginning, and birds are easily frightened and fly away, but when birds have adapted to such an environment, the bird repellent effect will be greatly reduced. Some bird repellents have sound pollution and chemical pollution, which are harmful to the ecological environment. The bird repellent sprayed and applied on the equipment still adheres to the equipment after completing the bird repellent task, affecting the symmetry of the pole tower hardware, the creepage distance of the hardware, etc., greatly reducing the life of the pole tower. Summary of the invention

[0005] In view of the technical problems existing in the prior art, the present invention aims to provide a controllable shedding bird-repellent material, a preparation method and an application thereof.

[0006] One of the purposes of the present invention is to provide a controllable shedding bird-repellent material, which comprises a component A and a component B; Component A includes methyl silicone rubber, bird repellent, dispersing adsorbent, weathering aid and colorant; Component B includes a crosslinking agent and an interface treatment agent. Preferably, component A comprises the following raw materials in parts by weight: Methyl silicone rubber 20~40 Bird repellent 5~25 Dispersed adsorbent 15~25 Weathering agent 5~15, and Colorant 1~3; Component B includes the following raw materials in parts by weight: Crosslinking agent 0.5~1.5 Interface treatment agent 0.1~0.3.

[0007] Preferably, the crosslinking agent comprises a silicate.

[0008] Preferably, the bird repellent comprises the following raw materials in parts by weight: Musk 0.5-5 parts, cinnamamide 0.5-10 parts, α-naphthol 0.5-8 parts, anthranilate methyl 0.5-8 parts, and camphor 0.5-5 parts.

[0009] Preferably, the dispersible adsorbent includes magnesium stearate and kaolin.

[0010] Preferably, the weathering aid includes alkali and sodium sulfate.

[0011] Preferably, the colorant includes one or more of color-changing ink, TPE ink, TPU ink or inorganic color paste.

[0012] Preferably, the interface treating agent includes γ-aminopropyltriethoxysilane and / or anilinomethyltriethoxysilane.

[0013] The second object of the present invention is to provide a method for preparing a controllable shedding bird-repellent material, the preparation method comprising: Musk, cinnamamide, α-naphthol, methyl anthranilate and camphor are mixed evenly, and then a dispersing adsorbent is added and stirred evenly to obtain a mixture 1; then methyl silicone rubber and a weathering aid are mixed evenly to obtain a mixture 2; Mix mixture 1 and mixture 2 evenly to obtain component A; Mix the crosslinking agent and the interface treatment agent evenly to obtain component B; The third object of the present invention is to provide a bird-repellent material with controllable shedding for use in repelling birds from power equipment.

[0014] Beneficial effects of the present invention: The present invention provides a bird-repellent material with controllable shedding, which includes component A and component B. Component A includes methyl silicone rubber, a bird repellent, a dispersing adsorbent, a weathering aid and a colorant; component B includes a cross-linking agent and an interface treatment agent. Methyl silicone rubber is used as an excipient for the bird-repellent material. It is cross-linked and cured under the action of the cross-linking agent, and can also improve the adhesion of the bird-repellent material. Methyl silicone rubber has excellent weather resistance, high and low temperature resistance and hydrophobicity, and can adapt to complex outdoor environments (such as rain and ultraviolet rays), ensuring that the bird-repellent material is stably attached to the surface of the pole tower for a long time without affecting the mechanical properties of the hardware. The interface treatment agent prevents the material from peeling off due to temperature differences or humidity changes, and improves the adhesion of the material to the interface of metal or cement. The weathering aid adjusts the overall weathering rate to ensure that the bird-repellent material can play a stable role during the high incidence period of bird damage, and then falls off naturally. The dispersing adsorbent serves as a slow-release carrier of the bird repellent to achieve the slow release of the bird repellent.

[0015] The bird repellent material has no mechanical connection with the pole tower, can be operated with power, and is easy to construct; the later maintenance is simple. The construction and maintenance points can be determined by observing the adhesion rate of this product; no manual intervention is required during the shedding process, which avoids the stress concentration of the hardware caused by the long-term adhesion of the bird repellent material and prolongs the mechanical life of the pole tower. It reduces the impact of the long-term adhesion of the bird repellent material on the creepage distance of the hardware and increases the electrical protection effect. At the same time, it avoids the corrosion of the construction interface to the facilities and prolongs the service life of the pole tower. DETAILED DESCRIPTION

[0016] According to a first aspect of the present invention, there is provided a controllable shedding bird-repellent material, the controllable shedding bird-repellent material comprising component A and component B; The component A comprises methyl silicone rubber, bird repellent, dispersing adsorbent, weathering aid and colorant; The B component includes a cross-linking agent and an interface treatment agent. In the present invention, methyl silicone rubber is used as an excipient for the bird repellent material, and is cross-linked and cured under the action of a cross-linking agent to form a three-dimensional network structure, thereby improving the adhesion of the material; methyl silicone rubber has excellent weather resistance, high and low temperature resistance, and hydrophobicity, and can adapt to complex outdoor environments (such as rain and ultraviolet rays), ensuring that the material is stably attached to the surface of the pole tower for a long time, while not affecting the mechanical properties of the hardware. Dispersed adsorbent The dispersed adsorbent is used as a sustained-release carrier for the bird repellent to achieve the slow release of the bird repellent. The weathering aid adjusts the overall weathering rate to ensure that the bird repellent material can stably function during the high-incidence period of bird damage, and then falls off naturally. The colorant is used to adjust the color of the bird repellent material and increase the bird's perception of the bird repellent material. The interface treatment agent forms a chemical bond with the surface of the substrate to prevent the bird repellent material from peeling off due to temperature differences or humidity changes, and improves the adhesion of the bird repellent material to the interface of metal or cement.

[0017] In a preferred embodiment of the present invention, component A comprises the following raw materials in parts by weight: Methyl silicone rubber 20~40 Bird repellent 5~25 Dispersed adsorbent 15~25 Weathering agent 5~15, and Colorant 1~3; The B component includes the following raw materials in parts by weight: Crosslinking agent 0.5~1.5 Interface treatment agent 0.1~0.3.

[0018] In the present invention, the weight of methyl silicone rubber is, for example, 20 parts, 21 parts, 22 parts, 23 parts, 24 parts, 25 parts, 26 parts, 27 parts, 28 parts, 29 parts, 30 parts, 31 parts, 32 parts, 33 parts, 34 parts, 35 parts, 36 parts, 37 parts, 38 parts, 39 parts or 40 parts.

[0019] In the present invention, the weight of the bird repellent is, for example, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 or 25 parts.

[0020] In the present invention, the weight of the dispersed adsorbent is, for example, 15 parts, 16 parts, 17 parts, 18 parts, 19 parts, 20 parts, 21 parts, 22 parts, 23 parts, 24 parts or 25 parts.

[0021] In the present invention, the weight of the weathering aid is, for example, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts or 15 parts.

[0022] In the present invention, the weight of the colorant is, for example, 1 part, 1.5 parts, 2 parts, 2.5 parts or 3 parts.

[0023] In the present invention, the weight of the crosslinking agent is, for example, 0.5 parts, 0.6 parts, 0.7 parts, 0.8 parts, 0.9 parts, 1.0 parts, 1.1 parts, 1.2 parts, 1.3 parts, 1.4 parts or 1.5 parts.

[0024] In the present invention, the weight of the interface treatment agent is, for example, 0.1 part, 0.15 part, 0.2 part, 0.25 part or 0.3 part.

[0025] In a preferred embodiment of the present invention, the crosslinking agent comprises a silicate.

[0026] In the present invention, silicate promotes the cross-linking and curing of methyl silicone rubber, and the cross-linked methyl silicone rubber has a three-dimensional network structure, which gives the bird-repelling material good flexibility and elasticity. This allows the material to adapt to various changes in shape without breaking under different installation environments, such as under natural conditions such as wind, sun, and rain, thereby ensuring the integrity and stability of the material. The methyl silicone rubber cross-linked by silicate can maintain stable performance over a wide temperature range. In a high temperature environment, the material will not soften or melt; in a low temperature environment, it will not become brittle or lose elasticity. This allows the bird-repelling material to be widely used in areas with different climatic conditions, ensuring that it can effectively play a bird-repelling role throughout the year. The material has good resistance to ultraviolet rays, oxygen, ozone, etc., and is not prone to aging, cracking, etc. During long-term outdoor use, it can maintain the stability of its physical and chemical properties, reduce the performance degradation caused by environmental factors, reduce the frequency of replacing bird-repelling materials, and save costs. In addition, the surface of the material has a low surface energy, which reduces the attachment of pollutants, keeps the appearance of the material neat and the bird-repelling effect.

[0027] In a preferred embodiment of the present invention, the bird repellent comprises the following raw materials in parts by weight: Musk 0.5-5 parts, cinnamamide 0.5-10 parts, α-naphthol 0.5-8 parts, anthranilate methyl 0.5-8 parts, and camphor 0.5-5 parts.

[0028] In the present invention, musk is a natural animal odor substance that has a strong warning effect on birds; cinnamamide has a pungent smell that interferes with the olfactory perception of birds; α-naphthol is a bitter substance that causes discomfort to birds after pecking; methyl anthranilate can volatilize a pungent smell to repel birds; camphor has a cool and pungent smell, which further enhances the repellent effect. After inhalation, birds produce an allergic anorexia reaction to form a regional avoidance reflex memory, which causes minimal harm to birds. Multiple odor and taste stimuli are superimposed to cover the sensitive thresholds of different birds, forming a broad-spectrum bird-repelling effect.

[0029] In a preferred embodiment of the present invention, the dispersible adsorbent includes magnesium stearate and kaolin.

[0030] In a preferred embodiment of the present invention, the mass ratio of magnesium stearate to kaolin is 1:2-3.

[0031] In the present invention, magnesium stearate promotes limited dispersion of each component during the preparation process, so that the volatile components are dispersed more evenly; kaolin is a porous material, which can effectively adsorb volatile components on the surface, and the porous material has a larger specific surface area, which can more effectively contact the air after weathering, so that the adsorbed volatile substances are slowly and evenly released into the air.

[0032] In a preferred embodiment of the present invention, the weathering aid includes alkali and sodium sulfate.

[0033] In a preferred embodiment of the present invention, the mass ratio of crystalline alkali and sodium sulfate is 1:1.

[0034] In the present invention, the ratio of the two is adjusted to control the shedding speed. When the mass ratio of crystalline alkali and thenardite is less than 1:1, the shedding speed is increased; when the mass ratio of crystalline alkali and thenardite is greater than 1:1, the shedding speed is reduced.

[0035] When the mass ratio of crystalline alkali and Glauber's salt is adjusted to 0.8:1.2, the shedding speed increases by 20%, and when the mass ratio of crystalline alkali and Glauber's salt is adjusted to 1.2:0.8, the shedding speed decreases by 20%.

[0036] In the present invention, the crystalline alkali is sodium carbonate, which loses water and weathers rapidly in a humid environment, accelerating the disintegration of the coating; the mirabilite is sodium sulfate, which weathers slowly when dry and absorbs water and expands when wet, further destroying the coating structure. The ratio of crystalline alkali to mirabilite adjusts the overall weathering speed through humidity response, and the difference in weathering rate in the summer humid season (1.5~1.8 mm / month) and the spring and autumn dry season (1.0~1.2mm / month) ensures that the coating can function stably during the high incidence period of bird damage (February to May), and then falls off naturally.

[0037] In the present invention, after the mass ratio of crystal alkali and sodium sulfate is fixed, the shedding time can also be controlled by controlling the thickness of the bird-repellent material. Within a certain range, the higher the thickness, the longer the shedding time.

[0038] In a preferred embodiment of the present invention, the colorant includes one or more of color-changing ink, TPE ink, TPU ink or inorganic color paste.

[0039] In a preferred embodiment of the present invention, the interface treatment agent includes γ-aminopropyltriethoxysilane and / or anilinemethyltriethoxysilane.

[0040] In a preferred embodiment of the present invention, the interface treatment agent comprises γ-aminopropyltriethoxysilane and anilinemethyltriethoxysilane, and the mass ratio of γ-aminopropyltriethoxysilane to anilinemethyltriethoxysilane is 1:0.4-0.5.

[0041] According to a second aspect of the present invention, a method for preparing a controllable shedding bird-repellent material is provided, the method comprising: Musk, cinnamamide, α-naphthol, methyl anthranilate and camphor are mixed evenly, and then a dispersing adsorbent is added and stirred evenly to obtain a mixture 1; then methyl silicone rubber and a weathering aid are mixed evenly to obtain a mixture 2; Mix mixture 1 and mixture 2 evenly to obtain component A; The crosslinking agent and the interface treatment agent are mixed evenly to obtain component B.

[0042] In the present invention, a method for preparing a controllable shedding bird-repellent material is provided, and the preparation method specifically comprises: Incense, cinnamamide, α-naphthol, methyl anthranilate and camphor are mixed according to the raw material ratio, stirred in an air-driven stirring tank at a stirring speed of 100-200 rpm for 10-15 minutes, and then a dispersing adsorbent is added and stirring is continued for 15-20 minutes to obtain a mixture 1.

[0043] Methyl silicone rubber and weathering aid were mixed in a high shear dispersion kettle according to the ratio, stirred at 1500 rpm to 2500 rpm for more than 10 minutes to obtain mixture 2.

[0044] Continue to turn on the high shear disperser, reduce the speed to 500 rpm-1000 rpm, add mixture 1 to mixture 2 in the high shear dispersion kettle while stirring, and after all are added, restore the speed to 500 rpm-2500 rpm, continue stirring for more than 20 minutes until dispersed evenly to obtain component A.

[0045] Mix the crosslinking agent and the interface treatment agent in a glass beaker or stainless steel barrel according to the raw material ratio, and stir pneumatically at 100-200 rpm for 1-3 minutes to obtain component B. When using, mix according to the mass ratio of component A: component B = 100: 1.5~2.0, stir evenly, and use scraping to apply directly on the metal interface, rock interface, and cement interface. The interface should be cleaned before scraping. Different construction thicknesses can be used according to different bird-repelling time requirements. In the summer humid season, its weathering and erosion reduction rate is 1.5~1.8mm / month, and in the spring and autumn dry season, its weathering and erosion reduction rate is 1.0~1.4mm / month. It will solidify and produce a bird-repelling effect 2 hours after scraping.

[0046] According to a third aspect of the present invention, there is provided an application of a controllable shedding bird-repellent material in repelling birds from power equipment.

[0047] Example The present invention provides 6 embodiments and 4 comparative examples, and the raw material ratios are shown in Table 1. The bird repellent formula is: 0.5 parts of musk, 7 parts of cinnamamide, 5 parts of α-naphthol, 7 parts of methyl anthranilate, and 4 parts of camphor.

[0048] The formula of the dispersing adsorbent is 1 part of magnesium stearate and 2.5 parts of kaolin.

[0049] The weathering aid formula is 1 part of crystal alkali and 1 part of Glauber's salt.

[0050] The colorant is inorganic color paste; Silicate is selected as the cross-linking agent; The interface treatment agent is γ-aminopropyltriethoxysilane and anilinemethyltriethoxysilane in a mass ratio of 1:0.5.

[0051] Table 1 Raw material ratios of Examples 1 to 7 and Comparative Examples 1 to 4

[0052] Preparation method: Incense, cinnamamide, α-naphthol, methyl anthranilate and camphor are mixed according to the raw material ratio, stirred in an air-driven stirring tank at a stirring speed of 100-200 rpm for 10-15 minutes, and then a dispersing adsorbent is added and stirring is continued for 15-20 minutes to obtain a mixture 1.

[0053] Methyl silicone rubber and weathering aid were mixed in a high shear dispersion kettle according to the ratio, stirred at 1500 rpm to 2500 rpm for more than 10 minutes to obtain mixture 2.

[0054] Continue to turn on the high shear disperser, reduce the speed to 500 rpm-1000 rpm, add mixture 1 to mixture 2 in the high shear dispersion kettle while stirring, and after all are added, restore the speed to 500 rpm-2500 rpm, continue stirring for more than 20 minutes until dispersed evenly to obtain component A.

[0055] Mix the crosslinking agent and the interface treatment agent in a glass beaker or stainless steel barrel according to the raw material ratio, and stir pneumatically at 100-200 rpm for 1-3 minutes to obtain component B. When using, mix according to the mass ratio of component A: component B = 100: 1.5~2.0 and stir evenly.

[0056] The experiment was conducted in spring. Several power equipment areas with bird activities were selected and the bird repellent materials of Examples 1 to 7 and Comparative Examples 1 to 4 were applied respectively. The coating thickness of the bird repellent materials of Examples 1 to 6 and Comparative Examples 1 to 4 was 3.5 cm, and the coating thickness of Example 7 was 5 cm.

[0057] Performance Testing Select multiple power equipment areas where birds are active, apply the bird-repelling materials of the embodiment and the comparative example respectively, record the surface drying time of the material according to the GB / T 1728 method, detect the surface hardness according to the GB / T 2411 method, and fully cure when the Shore A hardness reaches 30, record the curing time, observe the stay of birds within 12 hours, and record the number of stays of birds within a certain period of time. Observe the weathering and erosion of the bird-repelling material and the shedding time, and the test results are shown in Table 2.

[0058] Table 2 Performance test results of Examples 1 to 7 and Comparative Examples 1 to 4

[0059] The bird-repelling effect of the bird-repelling material of Comparative Example 4 gradually disappeared after 48 hours.

[0060] Based on Table 2, it can be seen that the number of bird stays is mainly related to the content of the bird repellent. Increasing the content of the bird repellent within a certain range can improve the bird repellent effect. When the thickness is constant, the higher the content of the weathering agent within a certain range, the higher the weathering erosion rate. Compared with the comparative example, the bird repellent material disclosed in this application has strong adhesion and controllable shedding. In order to meet the seasonal bird repellent needs, when using the configured bird repellent material, the shedding time can be controlled by controlling the coating thickness of the bird repellent material.
