manufacture example 1

[0137] 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...

Abstract

The invention relates to a method for preparing a deodorization type polyacrylic acid series water absorbing resin. The method is characterized in that (a) an oxide composition is utilized, and one component of the oxide composition is an oxidation reinforcing agent; (b) at least one component of the composition has fragrance; (c) the composition is not reacted before being in contact with a bodyfluid; (d) the composition can be rapidly reacted after being in contact with the body fluid to generate a substance which is relatively high in reaction properties; (e) the substance generated afterthe composition is reacted can be rapidly reacted with odor in the body fluid; (f) the reaction velocity or the reaction speed needs to be higher than the absorption speed of an absorbent; (g) the substance generated from reactions of the generated substance with the body fluid is safe and harmless and is odorless; (h) the average particle size of the composition is 100-300 [mu]m; (i) two components can be in contact with each other in the absorbent; and (j) the mass ratio of the oxidation reinforcing agent to an oxide is within (3:1)-(1:3). The resin prepared by using the method is capable ofrapidly removing odor of urea and in addition is effective for more than 24 hours.

Description

technical field [0001] The present invention relates to a deodorizing polyacrylic acid-based water-absorbing resin, a composition, and a method for producing the same. 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, wastewater treatment, soil water retention materials and other products, and has A polyacrylic acid-based water-absorbent resin with fast liquid absorption performance, a composition and a method for producing other absorbent products. 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 inconti...
