manufacture example 1

[0129] 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

[0134] Reference sample 1:

[0135] The reference sample used was just powder A with an equal amount of ethanol added.

Embodiment 2

[0137] Get 100g powder A and place in the Sanjin flask of 250ml, then Mitsui flask is placed on the high-speed mechanical stirrer, the rotating speed is transferred to 200r / s with the cinnamaldehyde ethanolic solution of 0.5g 10wt% wherein spraying with spray bottle, the rotating speed Adjust to 400r / s to mix and homogenize with an overhead stirrer for about 10min.

Abstract

The invention relates to an aldehydes deodorizing absorbent. The aldehydes deodorizing absorbent comprises: (a) aldehydes which are one of the following components or the combination of the followingcomponents: hydrocinnamic aldehyde (3-hydrocinnamic aldehyde, 3-hydrocinnamic aldehyde), intreleven aldehyde (deca-10-alkene-1-aldehyde), ligustral, melonal (2, 6-dimethyl-5-heptenal), methoxymelonal(6-methoxyl-2,6-dimethylheptaldehyde), methoxycinnamaldehyde (trans-4-methoxycinnamaldehyde), myracaldehyde (Myrac aldehyde) (isohexenyl cyclohexenyl formaldehyde) and grass green aldehyde (trifernal)(3-methyl-4-hydrocinnamic aldehyde, 3-phenylbutyraldehyde); and (b) unsaturated acrylic acid series monomer and a cross-linking agent aqueous solution, covalent bonds are formed at a position nearbya surface of the screened water-absorbent resin treated by a surface cross-linking agent, the adding amount of an aldehydes component based on the high-water-absorbent resin is 0.05-1wt%, and an obvious rapid deodorizing property is achieved.

Description

technical field [0001] The present invention relates to a deodorizing type polyacrylic acid water-absorbing resin, composition and production method thereof. 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 diapers, sanitary napkins, adult incontinence products ...
