manufacture example 1

[0109] The acrylic acid / sodium acrylate mixed monomer solution (the molar ratio of acrylic acid / sodium acrylate is 2.2 / 7.8) was transported through pipelines, the monomer concentration of acrylic acid / sodium acrylate was 44.0wt%, and the flow rate of the monomer solution was 8689kg / h. The temperature of the monomer solution is 80-90°C. Polyethylene glycol diacrylate (molecular weight: 522) with a concentration of 11.3 wt% was transported at the branch of the monomer solution pipeline, and the flow rate was 72 kg / h. In addition, the azobisisobutylamidine hydrochloride aqueous solution (flow 50kg / h) and the sodium persulfate aqueous solution (flow 60kg / h) with a concentration of 4wt% were mixed by a delivery pump to form an initiator mixed turbidity. Liquid, and the mixed turbid liquid is transported to the monomer through the branch of the monomer solution pipeline to carry out the polymerization reaction. The reaction solution is sprayed onto the reaction bed to form a monome...

Embodiment 1

[0114] Reference sample 1:

[0115] The reference sample used was just powder A with the same amount of purified water added.

Embodiment 2

[0117] Take 100g of powder A and place it in a 250ml three-necked flask, then place the three-necked flask on a high-speed mechanical stirrer, adjust the speed to 200r / s, and spray 1g of 10wt% N,N-phthalamide into it with a spray bottle For amido peroxycaproic acid (PAP) aqueous solution, adjust the speed to 400r / s to mix and homogenize with an overhead stirrer for about 10min.

Abstract

The invention relates to a high water absorption property resin with an acid deodorization property. The resin comprises (a) a deodorizer, (b) an unsaturated acrylic acid series monomer and (c) a cross-linking agent, wherein the deodorizer is acid and is stable in property under an acid condition (the pH value is 6.7), is relatively sensitive to pH value response to environments, can be solid granules or powder, or a solvent solution as well, or a pure liquid, is poor in volatilization and is long in retention time in the high water absorption property resin; and the addition amount of the deodorizer is 0.05-1 wt% of the high water absorption property resin. After surface treatment of the high water absorption property resin, the deodorizer is put into the high water absorption property resin, other properties of the resin are not greatly affected, but the deodorization property of the resin is remarkably improved.

Description

technical field [0001] The present invention relates to a superabsorbent resin with acidic deodorizing properties, the deodorizing effect is obviously increased, the composition and its manufacturing method. Specifically, it is suitable for absorbent articles, such as: adult paper diapers (disposable diapers), sanitary napkins, incontinence pads, mattresses, pet pads, wound care materials, building materials, waste water treatment and other products, and has deodorizing and absorbent properties. The polyacrylic acid-based water-absorbent resin with high performance, the composition and the production method of other absorbent articles. Background technique [0002] Super absorbent polymer (SAP), also known as super absorbent resin, is a cross-linked polymer containing strong hydrophilic groups that is insoluble in water but can absorb tens, hundreds or even thousands of times its own weight. polymer. Superabsorbent resins are now widely used in various fields such as diape...
