Embodiment 1

[0025] Embodiment 1 Preparation of a long-acting slow-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 cinnamic amide, 1g 1-naphthol, 0.5g bisphenol A, 0.05g methyl hydroxybenzoate, 0.5g ethylene glycol, Stir in a water bath at 30°C for 30 minutes, then add 1 g of ammonium persulfate and 12 g of N,N'-methylenebisacrylamide, stir evenly and let stand for 12 hours to obtain a colorless transparent gel with good mechanical strength.

Embodiment 2

[0027] Embodiment 2 Preparation of a long-acting slow-release bird repellent 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-propyl acrylamide, 20g musk-T, 70g cinnamamide, 10g 1-naphthol, 7.5g bisphenol A, 0.5g methyl hydroxybenzoate, 10g ethylene glycol, stirred in a water bath at 60°C for 10min, then added 5g ammonium persulfate, 90g N,N'-methylenebisacrylamide, stirred rapidly for 5min and then stopped, static After standing for 30 minutes, a colorless and transparent gel with a certain light yellow color was obtained, and the gel was broken after stirring again. The obtained product can be sprinkled on the ground for use, and the effect of repelling birds can last for more than 9 months.

Embodiment 3

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

[0030] Add 1500g N-isopropylacrylamide, 100g musk-T, 350g cinnamamide, 50g 1-naphthol to a 5L enamel reaction kettle equipped with an 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, stirred in an oil bath at 50°C for 10 minutes, then, 400g of N,N'-methylenebisacrylamide, stirred rapidly for 5 minutes, and cooled to After 25°C, the yellow liquid was discharged into barrels. Before construction, add 25g of hydrogen peroxide into the yellow liquid and manually stir it evenly, coat it on the exterior wall within 1 hour, crosslink at room temperature for 24 hours, a light yellow gel layer will form on the surface of the wall, and the bird repelling effect can be maintained for up to 9 months more than a month.

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 for electric power and high-speed rail, which is a long-acting slow-release bird repellent based on N-alkyl substituted acrylamide cross-linked polymers The preparation method of the agent gel. Background technique [0002] Birds are our friends and their presence maintains the planet's biodiversity. However, the ensuing negative impacts generally exist in airports, agriculture, forestry, electric power and other fields, especially the operation of power transmission and transformation lines and substations. In recent years, with the acceleration of the construction of electric power, high-speed rail, and airports in my country, the impact of birds on the safe operation of various fields 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 rep...
