Problems solved by technology

[0005] One of the purposes of the present invention is to address the deficiencies of the prior art. Based on the prior art, the preparation process of urine gel is relatively complicated and the cost is high. Secondly, because the bottom film of the diaper contains a large amount of calcium carbonate, it seriously affects the urine gel. For the technical shortcomings of the color development of calcium ions in urine, provide a water-based ink for intelligent detection of calcium elements

Embodiment 1～6

[0046] The aqueous polyurethane emulsion of embodiment 1~6 is the preparation of anionic aqueous polyurethane emulsion or cationic aqueous emulsion. According to the formula shown in Table 1, respectively mix diisocyanate and polymer polyol according to a certain molar ratio and disperse them evenly; at 65-85°C, add a chain extender (anionic chain extender or cationic chain extender) After reacting with the catalyst for 10-60 minutes (the first-stage reaction), add methyl ethyl ketone to dilute, and continue the reaction for 30-50 minutes (the second-stage reaction); cool to room temperature, and add a neutralizing agent (alkaline neutralizing agent neutralizes anionic Water-based polyurethane, acid neutralizer and cationic water-based polyurethane) and neutralized for 10-30 minutes; under strong stirring (500-1000rpm) add water for emulsification for 30-120 minutes, rotary evaporation to remove methyl ethyl ketone, to obtain water-based polyurethane emulsion.

Abstract

The present invention relates to the technical field of polymer materials and trace element detection, in particular to a water-based ink for intelligently detecting calcium and its preparation method and application. The water-based ink for intelligently detecting calcium is composed of color-developing ink and masking ink. In practical application, the masking ink is first printed or printed on the surface of the substrate, and then the color developing ink is printed or printed on the surface of the masking ink, wherein the masking ink can fully interact with the metal ions to be masked, and the masking efficiency is high , which can accurately reflect the calcium ion content in the urine. Moreover, the water-based ink for intelligent calcium detection has the advantages of good masking effect, simple preparation process, and low production cost compared with the urine gel of the prior art, and is not affected by the large amount of calcium carbonate contained in the bottom film of the diaper. The influence of the color development of calcium ions in the solution. The preparation method has the characteristics of simple process, low production cost and being suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of macromolecule materials and trace element detection, in particular to a water-based ink for intelligently detecting calcium and its preparation method and application. Background technique [0002] In the process of human life activities, the participation of various substances is required. Calcium is the most abundant element in the human body. It enjoys the title of "life element" and participates in various physiological functions and metabolic processes of the human body. Calcium is an indispensable and important substance in the process of human development. If the intake of calcium is insufficient, the human body will experience physiological calcium overdraft. For example, calcium deficiency in adults often manifests as weak legs and cramps, lack of concentration, osteoporosis, Symptoms such as joint pain; children with calcium deficiency often have symptoms such as night terrors, irritability, ni...
