Abstract
The invention discloses a controllable hydrogen release capsule and a preparation method and application thereof; the modified grease has alkalescence, oxidation resistance and improved hydrogen-binding capacity, and the release of hydrogen is delayed to a certain extent; meanwhile, the protective shell is arranged outside the core material, so that the hydrogen storage material is protected, and the safety in the transportation and storage processes is ensured. In the use process, after the protective shell is damaged, the hydrogen storage material reacts to generate hydrogen to be released, and the use requirement is met. The controllable hydrogen release capsule provided by the invention is portable and stable, can be suitable for various scenes needing hydrogen, and can be widely applied to daily maintenance, functional health care, hydrogen medicine and hydrogen agriculture.

RBH 4 +2H 2 O≒KBO 2 +4H 2 ↑
therefore, it is necessary to develop a capsule which can be stably stored and can stably react in water, in consideration of the characteristics of the hydrogen storage material.
The antioxidant is free radical absorbent, and comprises one or more of THBQ, BHA, BHT, PG, benzene polyphenol, vitamin E, guaiac resin, L-ascorbyl palmitate or astaxanthin; the lipophilic dispersant comprises sodium polyacrylate, rhamnolipid, sucrose ester or phosphatidyl choline; the oil and fat comprises medium chain triglyceride, oleum Olivarum, oleum Camelliae Japonicae, palm oil or hydrogenated vegetable oil; the gel is prepared by mixing one or more of acacia, carrageenan, gelatin, xanthan gum and propylene glycol alginate.

The invention also discloses a preparation method of the hydrogen-containing microcapsule, which comprises the following steps:
s1, core material preparation: mixing alkaline ionic liquid in parts by weight according to a certain molar ratio, mixing in a reaction kettle, stirring at the rotating speed of 100-200r/min for 1-2h, keeping the temperature at 25-50 ℃, sequentially adding a stabilizer, an antioxidant, a hydrogen storage material and a lipophilic dispersant in parts by weight, and continuously reacting for 1-2h to obtain a core material;

s4, filling capsules: filling the core material into the capsule shell by using a capsule filling machine to obtain a controllable hydrogen release capsule;
s5, forming and drying, namely putting the controlled hydrogen release capsule into a rolling dryer, quickly drying and forming for 10-20min at the temperature of 50-80 ℃, and drying for 5-6h at the temperature of 30-45 ℃ to obtain the finished product of the controlled hydrogen release capsule. The capsule has a particle size of 1-10mm and a particle weight of 0.05-0.8g.
In the embodiment, the grease can be hydrolyzed, so that the hydrogen storage material can be released better, and the alkaline ionic liquid is particularly arranged as a catalyst, so that the grease is hydrolyzed quickly, wherein the alkaline ionic liquid is one of a mixing agent and a modifying agent; the mixture is prepared by mixing one or more of glycerol, ethylene glycol or propylene glycol with N, N, N-trimethylglycine according to a molar ratio of 1-5:1, the modifier is prepared by mixing methanol solution of potassium hydroxide with imidazole and [ Bmim ] Br in equal molar ratio, more specifically, mixing the methanol solution of potassium hydroxide with imidazole in molar ratio of 1:1 reacting at 25-30 ℃ for 30-40min, adding the same mol of [ Bmim ] Br, magnetically stirring at 25-30 ℃ and 180r/min for reacting for 2-3h, adding a proper amount of anhydrous ether, reacting at 25-30 ℃ for 15-20h, circularly filtering and evaporating for 2-5 times, and finally drying in a vacuum drying box at 50-60 ℃ for 18-24 h.
In the storage process, the alkaline ionic liquid has the characteristics of stabilizing and hydrogen-binding effects; in the use process, when the shell is digested to enable the core material to be in contact with water in the external environment, the hydrogen storage material reacts with the water to generate hydrogen, the grease substances are hydrolyzed under alkaline conditions to generate alcohol substances and carboxylate, but the hydrolysis of the grease substances consumes hydroxide in the system instead of water, so the reaction can promote the hydrogen storage material to react forwards to generate enough hydroxide. In order to avoid the situation, after the current oil and fat substances are hydrolyzed to generate alcohol, an alcoholysis reaction can occur under the catalytic action of the alkaline ionic liquid, for example, triglyceride is converted into diglyceride and monoglyceride, the obtained product can be coated on the surface of the hydrogen storage material, the overflow rate of hydrogen is reduced, the utilization rate of the hydrogen is improved, and the functionality of the hydrogen is utilized to the maximum extent.
