Problems solved by technology

[0004] The purpose of the present invention is to provide a radiation indicating printing oil and its preparation method and application, which solves the problems in the prior art that there are many steps in the preparation process of the radiation indicating label, cumbersome operation, high waste rate and easy falling off in the process of using the label. At the same time, it solves the technical problems such as the instability of the ink emulsion, which leads to unevenness in the stamping process, and the color change and color difference after irradiation.

Embodiment 1

[0036] A preparation method of irradiation indicating ink, comprising the following steps,

[0037] (1) Mix 0.01% methyl orange, 0.5% chloral hydrate, 17% acrylic resin with water to form an indicator ink and inject it into the stamp, (2) stamp the indicator ink on the surface of the object to be irradiated, (3) absorb 25kGy Imprint changed from orange color to red after dose irradiation.

Embodiment 2

[0039] A preparation method of irradiation indicating ink, comprising the following steps,

[0040] (1) Mix 0.01% methyl orange, 0.5% chloral hydrate, 5% acrylic resin with water to form the indicator ink and inject it into the stamp, (2) stamp the indicator ink on the surface of the object to be irradiated, (3) absorb 25kGy Dose irradiation, due to the instability of the emulsion, causes unevenness in the stamping process, and the color change after irradiation is chromatic aberration.

Embodiment 3

[0042] A preparation method of irradiation indicating ink, comprising the following steps,

[0043] (1) Mix 0.01% methyl orange, 1% chloral hydrate, 20% acrylic resin with water to form the indicator ink and inject it into the stamp, (2) Put the indicator ink on the surface of the object to be irradiated, because the viscosity of the emulsion is too high , resulting in uneven stamping process, (3) 25kGy absorbed dose irradiation, uneven color change after irradiation.

Abstract

The invention relates to the technical field of dosimeters, in particular to irradiation indication stamp-pad ink as well as a preparation method and application thereof, and the irradiation indication stamp-pad ink comprises the following components in percentage by mass: 5-17% of high-molecular polymer emulsion, 0.01-0.05% of dye, 0.5-5% of dyeing assistant and the balance of solvent. The mark is convenient to use, the irradiation sterilization production condition can be observed and monitored on line, when the irradiation dose reaches 3-30 kGy, high-energy ionizing radiation can quickly oxidize groups in dyeing assistant molecules, so that the leuco dyeing assistant is changed into a new substance capable of enabling the dye to have color change, and the color of the mark is promoted to be changed.

Description

technical field [0001] The invention relates to the technical field of dosimeters, in particular to an irradiation indicating ink and a preparation method and application thereof. Background technique [0002] Radiochromic labels Dosimeters are usually opaque sticky labels that change color significantly under certain ionizing radiation, and indicate the amount of absorbed dose by the degree of color change. It can be used for visual observation and estimation of dose levels. It is suitable for qualitative and semi-quantitative field. [0003] In 2019, Luo Rui et al. disclosed a patent document entitled "Preparation Process of a Radiochromic Label Dosimeter", which also produces a color change visible to the naked eye under the action of a certain dose of ionizing radiation. Aiming at the problems of the above irradiation indicating label in the product preparation process that there are many steps, cumbersome operation, high waste rate and easy falling off during the marki...
