[0014] In summary, at present, in the known technical field, the antibacterial effect is mainly achieved by adding nano-silver ions or quaternary ammonium salt ions, but the above-mentioned method is used in personal daily necessities for women and children, which may cause potential safety hazards, which may cause harm to the user's health. Harm, there is no inquiry about the high antibacterial and deodorizing superabsorbent re...

Abstract

The invention discloses antibacterial and deodorant high-water-absorbent resin having the formula comprising the following components in parts by weight: 200 parts of acrylic acid, 40-80 parts of sodium hydroxide, 200-300 parts of deionized water, 0.02-2 parts of a beginning cross-linking agent, 4-100 parts of a tea leaf powder or a tea leaf extract, 0.05-0.6 part of an initiator, and 0.2-4 parts of a composite cross-linking agent. The high-water-absorbent resin can be widely applied in hygienic liquid-absorbing products; the added tea leaves and the extract thereof endow the high-water-absorbent resin with excellent antibacterial deodorant properties, and do not affect various absorption properties of the high-water-absorbent resin. The high-water-absorbent resin has the advantages of easily available raw materials, low cost, significant effects, and great economic benefits, social benefits and environmental benefits.

Example Embodiment

[0038] Example 1

[0039] Accurately weigh 200g acrylic acid, 60g sodium hydroxide, 300g deionized water, 0.1g N,N'-methylenebisacrylamide, 0.025g sodium sulfite, 0.025g sodium persulfate, 15g tea powder, polyethylene glycol dishrink 0.2g of a composite crosslinking agent prepared with glycerol ether and polyethylene glycol 200 in a 1:1 molar ratio, and then prepared according to the following steps:

[0040] 1). After mixing acrylic acid with deionized water, add sodium hydroxide for neutralization, the degree of neutralization is 82%;

[0041] 2) Add tea powder to the reaction system, stir and mix, and ultrasonically shake for 10 minutes, add N,N'-methylenebisacrylamide, continue stirring for 5 minutes, then gradually increase the temperature to 60°C, then add sodium sulfite and sodium persulfate to initiate Polymerization reaction for 90 seconds to obtain gel-like polymer;

[0042] 3). Granulate the gel-like polymer obtained in step 2) and dry it at a temperature of 160°C for 30 minutes to obtain a granular polymer;

[0043] 4) Mix deionized water and composite cross-linking agent to obtain a heat-treated cross-linking liquid. After this heat-treated cross-linking liquid is subjected to heat cross-linking surface treatment on the obtained granular polymer at a temperature of 160°C, after stirring, mixing and heating and drying Then, the highly absorbent resin of the present invention can be obtained.

Example Embodiment

[0044] Example 2

[0045] Accurately weigh 200g acrylic acid, 60g sodium hydroxide, 200g deionized water, 2g N,N'-methylenebisacrylamide, 0.1g sodium sulfite, 0.1g sodium persulfate, 30g tea extract concentrate, polyethylene glycol two 0.5g of compound crosslinking agent prepared with glycidyl ether and polyethylene glycol 200 in a 1:1 molar ratio, and then prepared according to the following steps:

[0046] 1), after mixing acrylic acid with deionized water, sodium hydroxide is added for neutralization, and the degree of neutralization is 72%;

[0047] 2) Add the tea extract to the reaction system, stir and mix, ultrasonically shake for 10 minutes, add N,N'-methylenebisacrylamide, continue to stir for 5 minutes, then gradually increase the temperature to 60°C, then add sodium sulfite and sodium persulfate Initiate the polymerization reaction for 90 seconds to obtain a gel-like polymer;

[0048] 3). Granulate the gel-like polymer obtained in step 2) and dry it at a temperature of 160°C for 30 minutes to obtain a granular polymer;

[0049] 4) Mix deionized water and composite cross-linking agent to obtain a heat-treated cross-linking liquid. After this heat-treated cross-linking liquid is subjected to heat cross-linking surface treatment on the obtained granular polymer at a temperature of 160°C, after stirring, mixing and heating and drying Then, the highly absorbent resin of the present invention can be obtained.

Example Embodiment

[0050] Example 3

[0051] Accurately weigh 200g of acrylic acid, 60g of sodium hydroxide, 260g of deionized water, 0.1g of N,N'-methylenebisacrylamide, 0.1g of sodium sulfite, 0.1g of sodium persulfate, 60g of tea extract, and polyethylene glycol 2 0.5 g of a composite crosslinking agent prepared with glycidyl ether and pentaerythritol in a 1:1 molar ratio, and then prepared according to the steps of Example 2, to obtain the super absorbent resin of the present invention.
