Problems solved by technology

[0004] The above-mentioned bird repellent has the following problems in use: one, crude oil bird repellent etc. are due to its use method being suspended in the open container, run into rainy weather, crude oil bird repellent and particle bird repellent etc., are diluted by rainwater , reduce the efficacy, and even be washed away by the rain, and lose the efficacy; 2. Due to the open field environment, after spraying the powder and water bird repellent, the smell is easily blown away by the wind, and the efficacy cycle is short, thereby increasing the dosage. manpower and material resources

Abstract

The invention provides a bird repellent and a preparation method of same. The preparation method includes steps of: 1) preparation of resin: mixing an initiator and water to obtain a first mixture liquid, mixing a polymerization monomer, a crosslinker, an emulsifier and water to obtain a second mixture liquid, adding the first mixture liquid and the second mixture liquid into a reactor to performa polymerization reaction, thereby obtaining an intermediate, and demulsifying, washing and drying the intermediate to obtain the resin; 2) preparation of the bird repellent: mixing an active component with the resin to form the bird repellent. In the bird repellent, the active component is adsorbed by the resin, so that the bird repellent has sustained release function and is prolonged in effective use time.

Description

technical field [0001] The invention relates to a bird repellent, in particular to a bird repellant and a preparation method thereof. Background technique [0002] Birds are one of the main hazards in the growth process of crops such as corn, rice, fruits and vegetables, and protecting crops from the harm of birds is conducive to improving the yield and quality of crops. [0003] Bird repellants are effective in protecting crops from birds. Existing bird repellents have dosage forms such as crude oil bird repellent, granular bird repellent, powder bird repellant and water agent bird repellant. The method of using the crude oil bird repellant is to place it in an open container, such as a plastic container, and hang the container on the crops; the method of using the powder and water bird repellent is usually to add water to dilute it, and spray it; The method of using the granular bird repellant is to sprinkle the bird repellant granules next to the crops, or wrap them in ...
