preparation example Construction

[0023] Preferably, the preparation method of the superabsorbent resin for removing adult urine odor comprises the following steps:

[0024] a. Acrylic acid, deionized water, water-soluble initiator, bridging agent, dispersant, and adsorbent material containing deodorant are polymerized in a reactor containing a stirring device to form a colloid;

[0025] b. The colloid formed in step a is crushed, granulated and neutralized with an alkaline substance, which includes but is not limited to sodium hydroxide;

[0026] c. The neutralized colloid is dried, pulverized, and sieved to obtain a semi-finished product of high-absorbent resin that removes the odor of adult urine;

[0027] d. The semi-finished product in step c is treated with a preset surface treatment temperature under the action of a surface cross-linking agent and a plant-based deodorant to obtain a finished product of high-absorbent resin that removes the odor of adult urine.

[0028] Further, the deodorant-containing...

[0096] Put 5 parts of dedecyltrimethylammonium chloride and 95 parts of kaolin into a high-speed mixer, and mix for 5 minutes at a speed of 2500 rpm to prepare an adsorbent material containing a deodorant. Add refined acrylic acid 25.0kg in the reactor with stirring, deionized water 46.4kg, 10wt% bridging agent polyethylene glycol 400 diacrylate 1.0kg, the adsorption material 0.25kg that contains deodorant, octadecyl 120g of phosphoric acid ester, after mixing evenly, the temperature of the reaction solution was cooled to 15°C, and initiators were added: 1.25kg of 1wt% hydrogen peroxide and 0.60kg of 1wt% ferrous sulfate. After the polymerization reaction is completed, the reactor is kept at 80° C. for 4 hours, and then the colloid is pressed out from the reactor for crushing and granulation. During granulation, 23 kg of 48% liquid caustic soda is added for neutralization. After the granulation is completed, the colloid is dried at 160°C for 60 minutes, and the moisture conten...

Abstract

The invention discloses a high-absorbability resin for removing odor of adult urine and a preparation method of the high-absorbability resin. The preparation method of the high-absorbability resin forremoving the odor of the adult urine comprises the following steps: a, polymerizing acrylic acid, deionized water, a water-soluble initiator, a bridging agent, a dispersing agent and an adsorbing material containing a deodorant in a reactor containing a stirring device to generate colloid; b, crushing and granulating the colloid formed in the step a, and neutralizing with an alkaline substance, wherein the alkaline substance comprises but is not limited to sodium hydroxide; and c, drying, crushing and screening the neutralized colloid to obtain a high-absorbability resin semi-finished productfor removing the odor of the adult urine. According to the high-absorptivity resin for removing the odor of the adult urine and the preparation method of the high-absorptivity resin, the production process is simple, the product absorptivity is excellent, and particularly, the odor of the adult urine can be effectively removed.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a preparation method of a high-absorbency resin for removing adult urine odor and a high-absorbency resin for removing adult urine odor. Background technique [0002] Super Absorbent Polymer, referred to as SAP, is a functional polymer material that is insoluble in water and organic solvents. Its molecular chain contains hydrophilic groups such as carboxyl, amide, and sulfonic acid groups. It is a strong hydrophilic polymer with a macromolecular cross-linked three-dimensional network structure. It has a high absorption capacity of hundreds to thousands of times its own weight. Water absorption function. Moreover, SAP, which is highly swollen after absorbing water, also has excellent water retention capacity, and the formed gel has good strength, and it is not easy to squeeze out water even if it is pressurized. [0003] There are already mature industrial production me...
