Embodiment 1

[0040] Example 1. Feasibility of direct coating of chemical indicating composition on the non-adhesive surface of pressure-sensitive tape to make steam sterilization indicating tape

[0041] - Chemical indicating composition preparation

[0042] Prepare a chemical indicator composition according to the formula in Table 2, and put the composition in a glass jar and grind it with zirconium beads for 48 hours.

[0043]

[0044]

[0045] - Preparation of chemical indicators (indicating tapes)

[0046] The chemical indicator composition is coated on the non-pressure-sensitive adhesive surface of the masking tape ("2213" or "2218" tape of 3M China Company). When coating, use a green No. 3 wire bar coating (RK Print-Coat Instruments Ltd., UK), and place it in an oven at 54° C. for 1 minute to dry after coating.

[0061]

[0062] Note: Comparative formulations are shown shaded (Formulation 1)

[0063] Note: When the chemical indicating composition does not include the film-forming resin, the "total weight of silicone-modified polymer and film-forming resin" in Table 4 refers only to "the total weight of silicone-modified polymer"

[0064] - Test for the transfer of chemical indicating compositions on indicating tapes to pressure sensitive adhesives

[0065] Test method is identical with embodiment 1. The results are scored on the following scale and are summarized in Table 5: 1 (complete transfer o...

Embodiment 3

[0071] Example 3. Test of transfer of chemical indicating composition to packaging material

[0072] - Preparation of chemical indicating composition and chemical indicator (indicating tape)

[0073] According to the formulation in Table 6, the chemical indicating composition and the corresponding indicating tape were manufactured in the same manner as in Example 1. Table 7 shows the glass transition temperatures of the different film-forming resins used in Table 6.

Abstract

The invention relates to a chemical indication composition, a steam sterilization indication tape using the chemical indication composition and a manufacturing method thereof. The chemical indication composition provided by the invention comprises: an indicator, an organosilicon modified polymer and a solvent, wherein the indicator comprises a bismuth compound, a sulfur source and a compound that can generate alkaline conditions when it is exposed to high temperature water vapor. The chemical indication composition can be directly applied to a non-adhesive surface of an adhesive tape, thus realizing preparation of the steam sterilization indication tape by one step.

Description

technical field [0001] The invention relates to a steam sterilization indicator and its application, more specifically, to a chemical indicating composition, a steam sterilization indicating tape using the chemical indicating composition and a manufacturing method thereof. Background technique [0002] Pressure steam sterilization is one of the most common and frequently used sterilization methods, and it is widely used in daily sterilization work in hospitals and clinics. Nowadays, chemical indicators used to test the sterilization effect are often made into cards, strips, tapes, etc. Among them, steam sterilization indicator tapes are widely used to seal sterilized item packages and indicate whether the item package has been pressure steam sterilized. process to prevent mixing with non-sterile packages. [0003] Steam sterilization indicator tapes usually consist of a pressure sensitive tape and an indicator. U.S. Patent US2889799 discloses the preparation process of thi...
