Description
Technical field
The present invention relates to a kind of developer, be specifically related to a kind of urine present gum and preparation technology thereof, for paper diaper etc.Care product.
Background technology
Along with market is increasing to the demand of paper diaper, paper diaper have generally replaced traditional diaper, extensivelyBe applied to baby and adult-incontinence person. Paper diaper in the market have stronger imbibition ability, paper diaperQuilt is not easy timely discovery after urinating and wetting, but the paper diaper continuation use of urinating after wetting very easily causes user (babyYoungster, adult-incontinence person etc.) allergic under wet environment, therefore, the timely replacing of paper diaper just seemsParticularly important.
If find that in time paper diaper are urinated wetly, need in paper diaper, increase certain coloring function. OrderThe front colour developing mode using in paper diaper is that ink urine is aobvious, and ink is urinated aobvious application and to a certain degree played visionThe effect of monitoring; Its principle is to add and be with coloured small-molecule substance in ink, when urine is in contact with itAfter, ink and these little molecules are washed away by urine, and color disappears, and reaches the effect of prompting. But thisDeveloping ink easily comes off under the continuous impact of urine, and display effect is unstable; And developing ink is by urineWhile washing away, between the chemical composition spreading apart at sandwich layer and sandwich layer, there is friction migration, cause diffusion area mistakeGreatly, affect attractive in appearance.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of urine present gum, not only have strongColoration, can also realize gradient variable color, and can keep colour developing stability, safe and reliable.
Another object of the present invention is to provide a kind of preparation technology who urinates present gum, simple to operation, be easy to push awayExtensively.
The technical solution adopted in the present invention is as follows for achieving the above object:
A kind of urine present gum, it comprises following component by weight percentage:
Microwax 8～10%;
Diethylene glycol dibenzoate 9～10%;
Foral 30～35%;
Stearic acid 3～5%;
Glycerin monostearate 10～12%;
Polyvinylpyrrolidone 20～30%;
Newtrex 8～15%;
Antioxidant 1～2%;
Bromophenol blue 0.1～1%;
Bromocresol green 0.1～1%;
Weld 0.1～1%.
Microwax has good luster, and fusing point is high, the feature of lighter color, and its close structure, hard and lubricious, have veryGood oil absorbency, can form stable, uniform lotion with multi-solvents, wax class, and have emulsibility. HydrogenationRosin and newtrex can improve original viscosity, the cementability of urine present gum in urine present gum of the present invention. Stearic acidIn the aobvious agent of urine of the present invention, be used as surfactant, improve the dispersion effect of each composition in formula. MonostearateGlyceride is used as emulsifying agent in the aobvious agent of urine of the present invention, impels melting between various compositions in urine present gum formulaClose. Polyvinylpyrrolidone is a kind of water suction high score polymer, and the effect in the aobvious agent of urine of the present invention is passableImprove the cohesive force of urine present gum, delay to urinate the diffusion velocity under the effect that shows agent urine, further raising colour developing is steadyQualitative.
As of the present invention one preferred embodiment in, described urine present gum also comprises and accounts for total raw material 1%wtModified montmorillonoid. Wherein the effect of modified montmorillonoid is to absorb moisture, avoid urinating present gum in air with a small amount ofContact with moisture and there is variable color. On the basis of such scheme, urine present gum of the present invention also comprise account for totalThe PH conditioning agent of raw material 1%wt. Wherein PH modulator effect is to play to a certain extent PH cushioning effect,Even if it is not easy to change that it is exposed in wet environment yet, strengthen the moisture resistance properties of urine present gum. Preferred in the present inventionPH conditioning agent be ethylenediamine tetra-acetic acid and salt thereof.
Urinate a preparation technology for present gum, according to above-mentioned formula, prepare by following steps:
1) temperature that reactor is set is 100-110 DEG C;
2) in reactor, add microwax, be stirred to the benzoic ether that adds successively half formula ratio after meltingClass plasticizer, whole Foral, stearic acid, glycerin monostearate, antioxidant, stir;
3) after above-mentioned raw materials is mixed evenly and fully melts, slowly add polyvinylpyrrolidone, control reactionThe temperature of still is 100-110 DEG C, mixes, and fully melts;
4) step 3) continue afterwards to add newtrex toward reactor, at the uniform velocity stir until melt also completely mixedClose evenly;
5) stop the stirring to raw material, second half benzoates plasticizer be divided into three parts of arbitrary proportion,Bromophenol blue continues to stir after adding reactor after mixing with a benzoates plasticizer;
6) stop after stirring stirring, after bromocresol green is mixed with a benzoates plasticizer, addReactor continues to stir, and stops stirring after stirring, and weld and a benzoates plasticizer are addedEntering reactor continues to stir;
7), after having stirred, use strainer filtering discharging;
8) cooling packing.
The present invention can also realize by following preferred scheme;
On the basis of above-mentioned technique, the preparation technology of urine present gum of the present invention is also included in step 1) itRear step 2) in reactor, pass into before CO2Protective gas.
In preferred embodiments of the present invention, step 8) in the filter screen that adopts be 80-120 object filter screen.
On the basis of above-mentioned technique, the preparation technology of urine present gum of the present invention is also included in step 4) andStep 5) between add the step of pH adjusting agent and modified montmorillonoid.
Compared to existing technology, beneficial effect of the present invention is:
1 variable color is strong: urine present gum of the present invention color contrast in variable color process is strongly remarkable, and user canBe easy to judge the variation of color and make corresponding judgement;
2 reactions are fast: urine present gum of the present invention has obvious change color after being flooded by urine at once, with fastPrompting monitoring personnel change;
3 gradient variable colors: urine present gum of the present invention can, according to urine pickup, occur gradient variable color; By ladderDegree variable color judges paper diaper water sucting degree and changes paper diaper in good time, will bring how convenient part.
4 heat endurances: urine present gum of the present invention has good stability under higher temperature;
5 resistances to impact: urine present gum of the present invention will, under the impact of the continuous dipping of urine and motion, not come offIndeformable;
6 environmental stabilities: urine present gum of the present invention has good resistance to the moisture of air, moist emptyNot easy to change in gas;
7 securities; Each composition of urine present gum of the present invention is nontoxic, environmental protection, and therefore urine present gum of the present invention hasSecurity reliability;
