Example 4: comparative application experiment

The solid bird repellent prepared by the invention is a porous massive solid, and has the advantages of no fluidity, porosity, good thermal stability, large essence loading capacity and the like. In this example, the results of high and low temperature tests comparing the bird repellent of the present invention with commercially available paste and liquid bird repellents are shown in the following table:

because the application environment on the electric power iron tower is quite severe, the general installation time is from the autumn of the current year to the autumn of the next year, and because birds migrate to the spring in the autumn and the birds breed in the autumn, the two seasons are the key seasons for preventing bird damage, so the high-low temperature test and the water solubility test are the key points for continuously and effectively judging whether the product can be continuously used, and if the sample property is changed in the low-temperature state, the using effect of the solid bird repellent prepared by the invention in the second year can not be ensured. The water solubility test is also a key index of the using effect of the solid bird repellent prepared by the invention on the electric power iron tower due to the severe weather such as rainwater. The test data show that the properties of the high-low temperature test and the water-solubility test of the solid bird repellent prepared by the invention are not changed, and the solid bird repellent is obviously superior to domestic similar products.

The invention has the advantages that bird repelling components and additives which are harmless to birds are adopted, and the volatile substances (styrene-isoprene-styrene block copolymer) are slowly released by utilizing a slow release carrier technology. A large number of experimental researches on a series of bird repellents show that the bird repellents are non-pesticide products, all components are non-toxic and harmless, the bird repellents do not cause harm to birds, do not pollute the environment, are convenient to use, have high content of bird repellent components and lasting effect, can continuously act for 227 days after being used once, and do not absorb water and are not conductive. The bird repellent can not influence the normal function of the bird repellent in severe weather conditions such as severe cold, high temperature, rain, strong wind and the like.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
