Embodiment 1

[0025] Example 1 Preparation of a long-acting sustained-release bird repellent for electric power and high-speed rail

[0026] In a 100mL beaker, add 25g N-ethylacrylamide, 1.5g Musk-T, 4.5g cinnamamide, 1g 1-naphthol, 0.5g bisphenol A, 0.05g methyl hydroxybenzoate, 0.5g ethylene glycol, After stirring for 30 minutes under 30°C water bath, 1g of ammonium persulfate and 12g of N,N'-methylenebisacrylamide were added, and after stirring evenly and standing for 12 hours, a colorless and transparent gel with good mechanical strength was obtained.

Embodiment 2

[0027] Example 2 Preparation of a long-acting sustained-release bird repellent special for electric power and high-speed rail

[0028] In a 1000mL glass reactor equipped with mechanical stirring, thermometer, reflux condenser and nitrogen introduction device, add 300g N-n-propylacrylamide, 20g Musk-T, 70g cinnamamide, 10g 1-naphthol, 7.5g bisphenol A, 0.5g methyl hydroxybenzoate, 10g ethylene glycol, stirring for 10min under 60℃ water bath, then adding 5g ammonium persulfate, 90g N,N'-methylenebisacrylamide, stirring rapidly for 5min and then stopping, After standing for 30 minutes, a light yellow colorless transparent gel was obtained, and the gel was broken after the stirring was turned on again. The resulting product can be sprinkled on the ground for use, and the bird repellent effect lasts for more than 9 months.

Embodiment 3

[0029] Example 3 Preparation of a long-acting sustained-release bird repellent special for electric power and high-speed rail

[0030] Add 1500g N-isopropylacrylamide, 100g Musk-T, 350g cinnamamide, and 50g 1-naphthol to a 5L enamel reactor equipped with electric heating oil bath jacket, mechanical stirring, thermometer, reflux condenser and nitrogen introduction device. , 30g of bisphenol A, 2.5g of methyl hydroxybenzoate, 50g of ethylene glycol, stirring for 10min under 50℃ oil bath, then, 400g of N,N'-methylenebisacrylamide, rapidly stirring for 5min, and then cooling to After 25°C, the material is discharged and the yellow liquid is packed into barrels. Before construction, add 25g of hydrogen peroxide to the yellow liquid and stir it by hand. Coat it on the outer wall within 1h, cross-link for 24h at room temperature, and form a light yellow gel layer on the wall surface. The bird repellent effect can maintain up to 9 More than months.

Abstract

The invention discloses a preparation method of timed-released bird repellents special for electric power and high-speed rails. The preparation method comprises the following steps: firstly, dissolving musk-T, cinnamamide, 1-naphthol, bisphenol A, a preservative and an antifreeze agent into N-alkyl substituted acrylamide at certain weight parts, mixing and stirring to obtain uniform dispersion liquid; and secondly, adding a cross-linking agent and an initiator into the dispersion liquid in the step I, standing for polymerization cross-linking reaction for 0.5-24h at 0-60 DEG C. The low-toxicity bird repellent composition is in-situ embedded and uniformly implanted into a gel system in a polymerization cross-linking reaction process of the N-alkyl substituted acrylamide, and the preparation method solves the technical problems that the existing universal bird repellents have high cost, low efficiency and poor weather resistance.

Description

Technical field [0001] The present invention relates to the technical field of bird repellents, in particular to a long-acting slow-release bird repellent special for electric power and high-speed rail, and is a long-acting slow-release bird repellent based on N-alkyl substituted acrylamide cross-linked polymer Preparation method of agent gel. Background technique [0002] Birds are friends of mankind, and their existence maintains the biodiversity of the earth. However, the ensuing negative impacts generally exist in airports, agriculture, forestry, power and other fields, especially the operation of power transmission and transformation lines and substations. In recent years, with the acceleration of my country's power, high-speed rail, and airport construction, the impact of birds on the safe operation of various fields has become particularly prominent. If on the basis of not harming the life of birds, enabling birds to safely leave their original places of activity is one ...
