manufacture example 1

[0184] 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 improving deodorization effect by a polyacrylic-acid-series water-absorbent resin component. The method includes that (a), a deodorization combination comprisinga plant component and a chemical component is provided; (b), the deodorization mode of the plant component can be physical smell neutralization or covering, or chemical reaction; (c), the plant component can obviously reduce initial foul smell of body fluids when being used individually; (d), the plant component in the combination is bamboo powder; (e), the grain diameter of the bamboo powder in the combination is below 800 micrometers. By the deodorization combination, the initial foul smell of the body fluids can be removed, and the deodorization state can continue 24 hours or above.

Description

technical field [0001] The present invention relates to a method for improving the deodorizing effect using a polyacrylic acid-based water-absorbing resin component. Specifically, it is suitable for absorbent articles, such as paper diapers (disposable diapers), sanitary napkins, incontinence pads, mattresses, pet pads, wound care materials, building materials, soil water retention materials and other products, and has fast liquid absorption [0002] The polyacrylic acid-based water-absorbent resin with high performance, the composition and the production method of other absorbent articles. Background technique [0003] 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 produ...
