The invention discloses a novel long-acting bird repellent and a preparation method thereof, and belongs to the technical field of chemical bird repelling. The bird repellent is composed of a core material and a wall material, the core material is a mixture of geraniol, cinnamyl aldehyde and allicin according to the mass ratio of 1: (1.2-1.5): (0.5-0.8), the wall material is modified beta-cyclodextrin and pumpkin seed protein nanoparticles, and the mass ratio of the geraniol, the cinnamyl aldehyde and the allicin is (5-7): (3-5): (1-3). The preparation method comprises the following steps: preparing the quaternary ammonium salt modified beta-cyclodextrin, including the core material, performing high-speed shearing emulsification on the quaternary ammonium salt modified beta-cyclodextrin and the pumpkin seed protein nano dispersion liquid, and performing freeze drying to obtain a final product. According to the invention, a stable and compact'molecular inclusion + physical barrier 'dual slow-release structure is constructed by utilizing the electrostatic interaction between the positively charged modified beta-cyclodextrin and the negatively charged protein nanoparticles, the release time of effective components is remarkably prolonged to 9 months or more, and the composite material has excellent rain wash resistance and ultraviolet resistance, and can be used for preparing a composite material with a good application prospect. And efficient, environment-friendly and long-acting bird repelling is realized.

The invention discloses sepiolite loaded allicin-copper composite antibacterial powder and a preparation method and application thereof.The preparation method comprises the following steps that under the stirring condition, a solution containing copper ions is dropwise added into sepiolite dispersion liquid, meanwhile, a sodium hydroxide solution is dropwise added till the pH ranges from 4 to 7, and copper-sepiolite mixed liquid is obtained; the copper-sepiolite mixed solution is stirred at the normal temperature, aged, subjected to suction filtration, dried, ground and sieved, then roasting treatment is conducted, and roasted sepiolite is obtained; dispersing the roasted sepiolite in a solvent B, and dropwise adding an allicin solution into the solvent B under a stirring condition to obtain an allicin-copper-sepiolite mixed solution; the allicin-copper-sepiolite mixed solution is stirred, washed, subjected to suction filtration, dried, ground and sieved, and the sepiolite loaded allicin-copper composite antibacterial powder is obtained. According to the sepiolite loaded allicin-copper composite antibacterial powder prepared by the preparation method disclosed by the invention, the remarkable antibacterial stability and antibacterial broad-spectrum performance are further improved, and the application range is wider.
