Problems solved by technology

[0005] The technical problem to be solved by the present invention: the traditional acrylic water-absorbing resin has poor biodegradability and is easy to cause pollution to the environment. In addition, the raw material comes from non-renewable petroleum resources. Therefore, it is necessary to develop a cat litter that is biodegradable, antibacterial and antibacterial, and strong water absorption. It is one of the problems that the industry needs to solve

Embodiment 1

[0043] The modified water-absorbing resin is prepared by the following steps:

[0044] Add 3.2g of cornstarch into the flask, add 82mL of deionized water, pregelatinize the starch in an oil bath at 90°C, and stir at 180rpm for 30min, then pass nitrogen into the flask, and lower the temperature to 60°C. Add 4.8g polyglutamic acid, 53mg tert-butyl hydroperoxide, 64mg ethylene glycol glycidyl ether, react for 2 hours, add 96mL of 30% sodium hydroxide solution, react for 1 hour, add glacial acetic acid to adjust the pH To 7, add absolute ethanol to precipitate the precipitate, and dry the precipitate at 80° C. to constant weight to obtain a modified water-absorbent resin.

Embodiment 2

[0046] The modified water-absorbing resin is prepared by the following steps:

[0047] Add 3.6g of tapioca starch into the flask, add 96mL of deionized water, pregelatinize the starch in an oil bath at 92°C, and stir at a speed of 200rpm for 45min, then feed nitrogen into the flask, and lower the temperature to 70°C. Add 5.2g polyglutamic acid, 55mg tert-butyl hydroperoxide, 66mg ethylene glycol glycidyl ether, react for 3 hours, add 104mL sodium hydroxide solution with a mass fraction of 30%, react for 1.5 hours, add glacial acetic acid to adjust When the pH reaches 7.2, absolute ethanol is added to precipitate out the precipitate, and the precipitate is dried at 85° C. to constant weight to obtain a modified water-absorbent resin.

Embodiment 3

[0049] Bacteriostats are made by the following steps:

[0050] Step S1, add 1.22mmol o-hydroxyacetophenone, 1.25mmol m-tolualdehyde and 5.3mmol sodium hydroxide into the flask, and add 10mL methanol as a solvent, heat to 100°C and reflux for 2.5h to obtain the intermediate 1;

[0051] Step S2, dissolve 1 mmol of intermediate 1 in 40 mL of methanol at 0°C, add 15 mL of 10% sodium hydroxide solution and 10 mL of 30% hydrogen peroxide, stir for 1.5 h, then warm up to room temperature and continue stirring 15h, extracted with ethyl acetate to obtain intermediate 2;

[0052] In step S3, 0.18 mmol of intermediate 2 and 8.45 mmol of anhydrous potassium acetate were dissolved in 7.2 mL of glacial acetic acid at 0° C., 0.36 mmol of iodine was added thereto, and heated to 98° C. for reflux reaction for 4 h. After cooling to room temperature, use Extracted with ethyl acetate to obtain intermediate 3;

[0053] Step S4, add 1 mmol of intermediate 3 and 5 mL of concentrated sulfuric acid...

Abstract

The invention discloses transparent and high-water-absorption starch cat litter and a preparation process thereof, belongs to the technical field of cat litter, and aims to overcome the defects that existing cat litter is poor in water absorption, biodegradability, antibacterial property and the like. The starch cat litter is prepared from the following raw materials in parts by weight: 40.4 to 50.6 parts of wood chips, 20.2 to 28.7 parts of modified water-absorbent resin, 12.5 to 16.8 parts of diatomite, 5.5 to 8.5 parts of a bacteriostatic agent and 4.2 to 8.3 parts of a binder. The invention also discloses the preparation process of the starch cat litter. The functional high polymer material modified water-absorbent resin is introduced on the basis of the wood chips and the diatomite, the modified water-absorbent resin is apolymer of starch modified polyglutamic acid, a three-dimensional space net structure is formed by cross-linking between glutamic acid chains and between starch chains, the property is guided by the structure, the problem that the water absorption of the cat litter is poor is solved, and meanwhile, the bacteriostatic agent is added, so that the safety and health of the pets are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cat litter, and relates to a translucent, highly water-absorbing starch cat litter and a preparation process thereof. Background technique [0002] As one of the most beloved animals, cats have begun to become pets in many families. In the process of raising pet cats, more attention should be paid to the pollution caused by their feces and urine excrement. On the one hand, free defecation is not conducive to the cleanliness and sanitation of the family. On the other hand, because the uric acid contained in the excrement itself has a strong odor, and the urea and other components in the urine are easy to decompose under the action of bacteria to produce ammonia, resulting in excrement with Very heavy smell, these smells will seriously pollute the indoor environment and affect people's healthy life. Materials used for pet waste disposal, especially cat waste, are called cat litter and may also be called p...
