Description
Technical Field
The invention belongs to the technical field of compositions, and particularly relates to a reflective slow-release bird repellent composition and a preparation method thereof.
Background
At present, bird damage faults of the transmission line are already a common fault type. Many birds are keen to nest on tall buildings and off-shore power line towers are the most desirable choice for their habitat, which leads to the following problems: firstly, when birds nest on the power transmission line tower, metallic nesting materials may fall down, which causes short circuit of a line insulator and causes short circuit failure and tripping of the power transmission line. Secondly, birds can discharge a large amount of excrement when the power transmission line is dropped and has a rest, and the excrement of the birds is attached to the surface of a circuit insulator and is difficult to remove, so that the insulator is polluted, the insulation grade of the insulator is reduced, and insulation breakdown and flashover are caused in severe cases. In addition, when birds move on the transmission line, wings and feet of the birds can be overlapped between lines, so that line faults are caused, and power failure loss is caused. Therefore, the bird repelling of the high tower of the power transmission line must be implemented, and the potential fault hazard possibly brought by the bird damage is eliminated.
Publication (bulletin) No.: CN101613548B relates to a chemical coating for preventing bird nesting, bird damage and corrosion, and also relates to a preparation method of the coating. The multifunctional bird nest-preventing corrosion-preventing coating comprises the following components in percentage by mass: 40-50% of modified fluorocarbon emulsion, 8-10% of plasticizer, 25-30% of nano-scale pigment and filler, 2-5% of silicone oil cross-linking agent, 5-8% of thixotropic agent, 0.5-1% of accelerator, 2-4% of bird repellent agent and 0.5-1% of defoaming agent. The coating additive has more dosage and general crack resistance and bird prevention effect.
Publication (bulletin) No.: CN107312450A relates to a bird-repellent paint, which comprises water-based silica gel resin, silicon dioxide, a solvent, an acid-base buffer agent, a flavoring agent, an inorganic reflective filler and the like. The bird-preventing and bird-repelling coating disclosed by the invention is reasonable in composition compatibility, green, environment-friendly, simple to operate and remarkable in bird-preventing and bird-repelling effect. The bird-preventing and driving paint can solve the potential safety hazard brought to the take-off and landing of airplanes when birds intrude into airport runways, the danger of the birds intruding into the power supply rails of high-speed rails and the excrement and noise pollution caused by the staying on buildings. The paint has poor water resistance, and although the types of the used inorganic reflective fillers are more, the reflective effect is general.
