Problems solved by technology

However, this kind of color-developing ink is easy to fall off under the continuous impact of urine, and the display effect is unstable; and when the color-developing ink is washed by urine, frictional migration occurs between the chemical components diffused in the core layer and the core layer, resulting in diffusion The area is too large, affecting the appearance

Embodiment 1

[0055] A urine-developing glue, prepared according to the following process steps:

[0056] 1) Set the temperature of the reactor to 100°C;

[0057] 2) Add microcrystalline wax into the reaction kettle, stir until melted, then add half of the formula amount of diethylene glycol dibenzoate, perhydrogenated rosin, stearic acid, glyceryl monostearate, antioxidant, and stir Uniform;

[0058] 3) After the above raw materials are mixed evenly and fully melted, slowly add polyvinylpyrrolidone, control the temperature of the reactor to 100°C, mix evenly, and fully melt;

[0059] 4) After step 3), continue to add polymerized rosin to the reactor, stir at a constant speed until it melts and mixes completely;

[0060] 5) Add ethylenediaminetetraacetic acid and modified montmorillonite to the above mixture in turn, and stir;

[0061] 6) Stop stirring the raw materials, divide the other half of the benzoate plasticizer into three parts in any proportion, mix bromophenol blue with one pa...

Abstract

The invention discloses a wetness indicating adhesive and a preparation technology thereof, and the wetness indicating adhesive is used for nursing products such as paper diapers, etc.. The wetness indicating adhesive comprises, by weight, 8-10% of microcrystalline wax, 9-10% of a benzoate plasticizer, 30-35% of hydrogenated rosin, 3-5% of stearic acid, 10-12% of glycerin monostearate, 20-30% of polyvinylpyrrolidone, 8-15% of polymerized rosin, 1-2% of an antioxidant, 0.1-1% of bromophenol blue, 0.1-1% of bromocresol green and 0.1-1% of a yellow dye. The wetness indicating adhesive is prepared by steps of melting, stirring, discharging, packaging and the like. The wetness indicating adhesive has advantages of strong coloration effect, gradient coloration, coloration stability, safety and reliability.

Description

[0001] technical field [0002] The invention relates to a color-developing glue, in particular to a urine-developing glue and a preparation process thereof, which are used in nursing products such as paper diapers. [0003] Background technique [0004] With the increasing demand for diapers in the market, diapers have generally replaced traditional diapers and are widely used in infants and adult incontinence. The diapers currently on the market have a strong liquid absorption capacity, and it is not easy to find out when the diapers are wet. However, the continued use of the wet diapers will easily cause the skin of the user (baby, adult incontinent person, etc.) in a humid environment. Allergies, therefore, timely replacement of diapers is particularly important. [0005] If you want to find that the diaper is wet in time, you need to add a certain color rendering function to the diaper. At present, the color development method used in diapers is ink urine display. Th...
