Description
Technical field
The present invention relates to a kind of absorbent device, particularly a kind of absorbent device of the Hdyrophilic polyurethane flexible foams that contains ion exchanging function.
Background technology
The polyurethane full name is polyurethanes, is the general designation that contains the macromolecular compound of repetition carbamate groups (-NHCOO-) on main chain.It is to be formed by organic diisocyanate or polyisocyanates and dihydroxy or polyol addition polymerization, and this unit is formed by isocyanate group and hydroxyl reaction, and reaction equation is as follows :-N=C=O+HO
-→-NH-COO-.
The polyurethane flexible foam material, as a kind of novel high molecular synthetic material, mostly is open-celled structure, has certain elasticity and flexibility.Therefore, have that density is low, elastic recovery good, the performances such as sound-absorbing, ventilative, insulation, main as pad materials such as cushion material mattress, vehicle seat medicated cushions, also soft bubble is used as to filtering material, deadener, packing, ornament materials, packaging material and heat-barrier material etc. on industrial and civilian, the soft polyurethane foam of perforate simultaneously has good sound absorption shock absorbing function, can be used as indoor deadener.
The patent No. is that the CN1095988 patent of invention discloses and usings drug powder or extract and join in polymer raw and carry out foaming as additive, has obtained the functional urethane foam plastics with some function.
The patent that application number is 200710009148.1 provides a kind of charcoal-containing polyurethane foam composite material, in the raw materials of these plastics, except preparing, the necessary foaming of polyurethane soft foamed plastics is former, auxiliary material, also add ultra-fine bamboo charcoal powder or charcoal powder, also add the compositions such as far-infrared powder, the mycopowder that disappears, silver ion powder, tea powder or Chinese herbal medicine powder simultaneously, give composite and there is the functions such as absorption harmful gas, disinfection, but this material is mainly used in daily living article
Such as medicated pillow, mattress or house decorative material etc.
The absorbent device that the patent of invention that application number is 200810176855.4 and 200810176856.9 discloses a kind of ion exchange fiber non-woven and applied it, this invention forms by dry non-woven cloth processes after being mixed in proportion by ion-exchange fibre and natural fiber, regenerated fiber, synthetic fibers.But the ion exchange fiber non-woven that this invention obtains is fast to excremental seepage velocity, the liquid storage ability is lower, so that the inorganic salt composition in Excreta is difficult to and non-ion-exchange fibre generation ion exchange in making cloth within the very short time, and the effect of actual ions exchange is less.
In view of the foregoing, the invention discloses a kind of hydrophilic polyurethane flexible foams containing ion exchange material, and the polyurethane flexible foam material is applied in disposable sanitary articles as a kind of functional composite material.The hydrophilic polyurethane flexible foams has certain seepage velocity to body fluid, can effectively prevent the seepage of liquid, simultaneously, body fluid is had to physisorption and liquid storage effect, body fluid is the inorganic ion composition in people's urine particularly, can be from top to bottom and ion exchange resin generation ion exchange, the inorganic ion composition in the urine of decrease body fluid, particularly people.Therefore, a kind of hydrophilic polyurethane flexible foams containing ion exchange material has filtering function preferably to the inorganic ion composition in people's body fluid, and domestic and foreign literature yet there are no relevant report at present.
In hygienic article, the absorption carrier of body fluid is mainly born by super absorbent resin, and super absorbent resin is mainly polyacrylic acid (salt) class super absorbent resin, its in super absorbent resin market, the world in occupation of leading position, account for more than 80% of world SAP total output, formed through polymerisation in solution or suspension polymerization copolymerization by acrylic acid or its esters and monomer with two degrees of functionality.Yet, polyacrylic acid (salt) is although the class super absorbent resin has the advantages such as absorption speed is fast, water absorbent rate is high, good heat resistance than other synthetic class super absorbent resin, but polyacrylic acid (salt) class super absorbent resin belongs to polyelectrolyte, salt resistant character is poor, has a strong impact on its application performance.
Yet people's body fluid components complexity, as people's urine is mainly carbamide and various inorganic ion, as Cl
-, Na
+, K
+, SO
4 2-deng.Because High hydrophilous resin belongs to polyelectrolyte, various ion components all can produce common-ion effect to its water absorption course, therefore, these compositions all produce serious influence to the water absorbing capacity of super absorbent resin, the liquid absorbency rate that shows as High hydrophilous resin significantly descends, cause the absorbent properties decline of the absorptive core of hygienic article to urine, affect the serviceability of hygienic article, easily produce urine leakage in child's wearing process as hygienic article, simultaneously, the surface amount of bleeding back of hygienic article increases, the decline of dry and comfortable property, easily cause the erythema of child's skin etc.
In view of the urine inorganic ion composition of people's body fluid, particularly people, to the having a strong impact on of super absorbent resin absorbent properties, the present invention designs a kind of polyurethane flexible foam material that ion in urine is had to ion exchanging function.By the various inorganic salt compositions in ion exchange resin effect separation, elimination people's urine, increase substantially the water absorbing capacity of High hydrophilous resin in the hygienic article absorptive core, simultaneously, also improve salt resistant character and all night performance of water-absorbing resin.
Summary of the invention
The objective of the invention is to provide the absorbent device of the high absorbency of a kind of high salt tolerant, it is characterized in that described absorbent device contains the hydrophilic polyurethane flexible foams with ion exchanging function; The effect of the ion exchange material by the polyurethane flexible foam material, reach separation, eliminate the various inorganic salt compositions in people's urine, increase substantially water absorbing capacity and the salt resistant character of High hydrophilous resin in the absorptive core of absorbent device, reduce the use amount of High hydrophilous resin.
To achieve these goals, the technical solution used in the present invention is: described
