Description
Technical Field
The invention relates to hydrogel bait and a preparation method thereof.
Background
The bait, i.e., food eaten by fish, is food for attracting fish to get up during fishing, and further is all usable substances capable of gathering fish or attracting fish to get up during fishing. Li Meng Jie uses corn stalk, mica powder and active carbon as bionic bait filler, which is environment-friendly and degradable, avoids the pollution to water quality, then carries out hydroxylation treatment on the bionic bait filler, and then carries out esterification reaction with acrylic acid, thus achieving the purpose of grafting acrylic acid on the surface of the bionic bait filler, and improving the problems of weak acting force and poor interface binding force of the traditional bionic bait filler and a substrate. The main material of the bait of the invention has natural and pure cereal fragrance, vanillin is added, the olfactory organ of fish can be stimulated, and the bait has rich animal and plant protein and amino acid, and food attractant component is added, so that the taste of the bait is improved, the fish can be promoted to eat first, and the fish can be bitten. (Yangbang-a fragrant bait and its preparation method: China 201810907456.4[ P ].2020-02-21.)
However, the bait of the invention can not continuously lure fish, and the bait with the approximate first-order release rate can be prepared by mixing anionic high polymer, polyvinyl alcohol, egg white powder, cationic fish luring agent (2-carboxyethyl) dimethyl sulfonium bromide, preservative and mung bean starch. The hydrogel is a gel in which water is used as a dispersion medium. Hydrogels are excellent vehicles because hydrogels do not readily dissolve; has water swelling property, and the swelling process is the drug release process. The anionic polymer is sodium alginate and sodium polyacrylate. The (2-carboxyethyl) dimethyl sulfonium bromide can receive stimulation of low-concentration chemical substances in a water body through the smell of aquatic animals, can distinguish the chemical substances, is extremely sensitive, and can increase the contact area between the (2-carboxyethyl) dimethyl sulfonium bromide and an external water environment through folds in the smell speak in a low voice so as to improve the sensitivity of the smell. Therefore, the fish, the shrimp and the crab have strong feeding physiological mechanism to the peculiar smell of the (2-carboxyethyl) dimethyl sulfonium bromide. Compared with the fish luring agent of the common bait, the time for releasing the fish luring agent of the bait is obviously prolonged, and the fish luring agent can be continuously released in water, so that the fish biting times are improved, and the fishing effect is good.
The invention aims to provide hydrogel bait and a preparation method thereof, and the hydrogel bait with the first-level release rate of the fish luring agent is obtained, and the bait can effectively and continuously release the fish luring agent to achieve the purpose of long-acting fish luring and bait swallowing.
Therefore, the technical scheme adopted by the invention is as follows:
the hydrogel bait consists of the following effective components in percentage by mass: 5-8% of polyvinyl alcohol; 0.85-1.5% of egg white powder; 1.5 to 3 percent of anion high polymer; 0.5 to 1 percent of cation fish luring agent; 0.2 to 0.5 percent of preservative; 0.5-1% of mung bean starch; 88-95% of deionized water.
Further, the anionic polymer is sodium alginate and sodium polyacrylate, and the mass ratio of the sodium alginate to the sodium polyacrylate is 1: 0.5-2.
Sodium alginate and sodium polyacrylate are mixed by monomers with different molecular weights, wherein: molecular weight 3000 sodium polyacrylate mass: mass of sodium polyacrylate with molecular weight of 12000: the mass of 800 ten thousand sodium polyacrylate with molecular weight is 1: 0.5-3: 0.3 to 2; mass of sodium alginate with molecular weight of 3700: the mass of the sodium alginate with the molecular weight of 64000 is 1: 0.5-2.
The cation fish luring agent is (2-carboxyethyl) dimethyl sulfonium bromide.
(2-carboxyethyl) dimethylsulfonium bromide has the following structural formula:
the preservative is potassium sorbate.
The invention also adopts the following technical scheme:
weighing the components according to a set proportion, dissolving an anionic polymer in deionized water, slowly adding polyvinyl alcohol, egg white powder, (2-carboxyethyl) dimethyl sulfonium bromide, potassium sorbate and mung bean starch, magnetically stirring for 40 minutes at room temperature, stirring for 2.5 hours at a constant temperature of 95 ℃ in an oil bath kettle, completely mixing the system to obtain a clear and transparent viscous solution, pouring the solution into a mold, standing for 1.5 hours to remove bubbles, freezing for 20 hours at-25 ℃, taking out the solution, thawing for 4.5 hours, circulating for 3 times in a freezing-thawing manner, pouring the hydrogel out of the mold, and placing the hydrogel in pure water to remove unreacted monomers to obtain the hydrogel bait.
Compared with the prior art, the invention has the following beneficial effects: the method comprises the following steps of mixing anionic high polymer, polyvinyl alcohol, egg white powder, a cationic fish luring agent, an antiseptic and mung bean starch to prepare the hydrogel bait, combining the anionic high polymer and the cationic fish luring agent, enabling the polyvinyl alcohol to form hydrogen bonds with carbonyl groups of the egg white powder through hydroxyl groups to prepare the bait with the fish luring agent close to the first-level release rate, and enabling the xerogel to expand in volume after water absorption to release the loaded fish luring agent, so that the effect of effective and continuous release can be achieved.
