Problems solved by technology

If the formula process of the sterilization indicator tape is not treated with suitable waterproof, anti-sticking and anti-deinking treatment, or the waterproof coating is not resistant to high temperature steam and has poor adhesion to the tape substrate, the sterilization indicator ink and the medical masking tape substrate will not be compatible. If the adhesion is not good, the indicator ink is more likely to fall off, which may lead to misjudgment by the sterilizer, and t

Embodiment 1

[0018] The masking paper is beige masking paper provided by Smith Paper, with a grammage of 60g / ㎡, a thickness of 0.12mm, a tensile strength of >42N, an elongation of 17%, and a moisture content of 4.5%. The width of masking paper is 1280mm.

[0019] The toughening agent is natural rubber (Vietnam 3L standard rubber), urea-formaldehyde resin, 120# mineral oil, stearic acid, zinc oxide, diphenylguanidine, and elemental sulfur are respectively 15%, 15%, 60%, and 5% by mass percentage , 2%, 2%, 1% mixture. Dissolve natural rubber in 120# mineral oil and ball mill for 12 hours, then add urea-formaldehyde resin to ball mill for 12 hours, then add stearic acid, zinc oxide, diphenylguanidine and elemental sulfur, and air ball mill for 1 hour. A uniform translucent light yellow toughening agent was obtained.

[0020] The adhesive is Henkel / DURO-TAK87-2677 acrylic pressure-sensitive adhesive from Germany, in which the effective solid content of acrylic acid is 98%, and the thickness ...

Embodiment 2

[0032] The masking paper is beige masking paper provided by Smith Paper, with a grammage of 75g / ㎡, a thickness of 0.14mm, a tensile strength of 44N, an elongation of 17%, and a moisture content of 4%. The width of masking paper is 1280mm.

[0033] The toughening agent is natural rubber (3L standard natural rubber imported from Vietnam), urea-formaldehyde resin, 120# mineral oil, stearic acid, zinc oxide, diphenylguanidine, and elemental sulfur are respectively 20%, 15%, 56%, and 5%, 2%, 1%, 1% mixture.

[0034] The adhesive is Henkel / DURO-TAK87-2677 acrylic pressure-sensitive adhesive from Germany, in which the effective solid content of acrylic acid is 98%, and the thickness of the high-temperature-resistant adhesive on the textured paper is 22 μm.

[0035] The preparation of waterproof sealing ink: antimony tin oxide (self-made, preparation method is the same as embodiment one, mass percent is 5%), polymethyl methacrylate (Lucite 2044, 15%), natural rosin (5%), Phenolic re...

Abstract

The invention discloses a sterilization monitoring indicating tape without printing ink transfer and residual glue, the sterilization monitoring indicating tape sequentially comprises a bonding agentlayer, textured paper, an indicating ink layer, a waterproof sealing ink layer and a release agent layer, after the textured paper is printed with the indicating ink layer, the textured paper is toughened and treated by a flexibilizer, and the waterproof sealing ink is prepared from the following components in percentage by mass: 5-10% of nano tin oxide, 10-15% of polymethyl methacrylate, 3-5% ofnatural rosin, 5-15% of toughened modified phenolic resin, 50-60% of an oily solvent and 5-15% of a plasticizer. The sterilization monitoring indicating tape prepared by the invention has the characteristics of preventing ink from falling off and transferring so as to avoid glue residue.

Description

technical field [0001] The invention relates to a sterilization monitoring indicating tape with no ink transfer and no residual glue, and belongs to the technical field of medical sterilization indicating tapes. Background technique [0002] The sterilization effect monitoring of medical sterilization packages is a key link in the control of infection in medical institutions, and the sterilization indicator tape is used to form a closed sterile barrier system for medical packaging materials, pasted on the outside of the dressing package or surgical instrument package, the indicator tape The color-changing ink stripes on the packaging are used to indicate whether the item package has been sterilized, so as to distinguish non-sterile packages. After sterilization, if the color change of the indicator tape is uneven or incomplete, it can indicate that the package has not been sterilized according to the conditions; when packing, if no packing tape is used, the sterilization ind...
