Embodiment 1

[0023] In a 1000ml three-necked flask equipped with a mechanical stirrer, a heating device, and a condensing reflux device, add 200 g of deionized water and 50 g of 2.5 wt % maleic anhydride, 4.8 g of urea, 0.5 g of ammonium chloride, and 0.5 g of resorcinol Phenol was stirred and dissolved evenly. Add 5g of musk-T, 20g of cinnamic amide, and 2g of ethyl hydroxybenzoate mixture slowly dropwise into the flask to form an emulsion; then add 11.28g of 37% formaldehyde solution (formalin), slowly heat up to 56°C for 4 hours, cool Washing with water for 5 times, vacuum drying to obtain the microcapsule product with the effect of promoting bird repelling.

Embodiment 2

[0025] In a 1000ml three-necked flask equipped with a mechanical stirrer, a heating device, and a condensing reflux device, add 350g of deionized water and 75g of 1wt% maleic anhydride, 20g of urea, 4g of ammonium chloride, and 3.6g of resorcinol and stir to dissolve evenly . Slowly drop the mixture of 60g musk-T, 75g cinnamic acid and 5g benzoic acid into the flask to form an emulsion; then add 30g 37% formaldehyde solution (formalin), slowly raise the temperature to 60°C for 4 hours, wash with cooling water for 3-5 Second, vacuum drying to obtain a microcapsule product with the effect of promoting bird avoidance.

Embodiment 3

[0027] In a 1000ml three-necked flask equipped with a mechanical stirrer, a heating device, and a condensing reflux device, add 250 g of deionized water and 40 g of 5 wt % maleic anhydride, 4 g of urea, 0.5 g of ammonium chloride, and 0.6 g of resorcinol and stir to dissolve uniform. Slowly drop a mixture of 5g musk-T, 25g cinnamic acid, and 2.5g benzoic acid into the flask to form an emulsion; then add 10g of 37% formaldehyde solution (formalin), slowly raise the temperature to 50°C for 3 hours, and wash with cooling water for 3~ 5 times, vacuum-dried to obtain a microcapsule product with the effect of promoting bird avoidance.

Abstract

The invention discloses a preparation method for a micro-capsulate type sustained-release bird repellent mixture. According to the method, a micro-capsulate with a core-shell structure is synthesized mainly by an emulsion polymerization manner, and an ingredient with a bird repelling effect is used as a core material to be wrapped and fixed in the micro-capsulate. Through the controlled-release function of the micro-capsulate, the technical problem that a conventional universal bird repellent product is high in cost, low in efficiency and poor in weather resistance is solved.

Description

technical field [0001] The invention relates to the technical field of biological and agricultural new materials, in particular to a preparation method of microcapsules with the function of promoting bird avoidance. Background technique [0002] Birds are our friends and their presence maintains the planet's biodiversity. However, the ensuing negative impacts generally exist in the fields of airports, agriculture, forestry, and electric power. Especially in recent years, with the acceleration of airport construction in my country, the impact of birds on flight safety is particularly prominent. On the basis of not harming the lives of birds, it is one of the important topics in the field of animal repelling technology research to make birds safely leave their original activity places. [0003] Traditional bird repelling techniques include physical and chemical methods to repel birds, such as loud sound devices, placing scarecrows, reflective sequins, etc., using acoustic and...
