Corrosive liquid reagent bottle sticker protective adhesive tape and manufacturing method thereof

Abstract

The invention discloses a corrosive liquid reagent bottle sticker protective adhesive tape and a manufacturing method thereof, and relate to the technical field of industrial adhesive tapes. The corrosive liquid reagent bottle sticker protective adhesive tape comprise an adsorption layer with pores for absorbing corrosive liquid reagents, an adhesive layer is arranged on the inner side of the adsorption layer, and leakage-proof layers for preventing the corrosive liquid reagents from seeping are arranged on the outer side and the bottom end of the adsorption layer. The top end face of the adsorption layer is exposed and used for making contact with the corrosive liquid reagent, and then absorption of the corrosive liquid reagent by the adsorption layer is achieved. The corrosive liquid reagent bottle sticker protective adhesive tape can be adhered to the bottleneck part of a reagent bottle through the adhesive layer, and the problem that the bottle label is corroded due to the fact that the corrosive liquid reagent drips onto the bottle label can be effectively avoided through the blocking and adsorption effects of the protective adhesive tape.

Description

technical field [0001] The invention relates to the technical field of industrial tapes, in particular to a protective tape for corrosive liquid reagent bottles and a manufacturing method thereof. Background technique [0002] In the inspection and testing process of food and drugs, some strong acid reagents, such as sulfuric acid, hydrochloric acid, nitric acid, etc., are often used. At present, most of the corrosive acid reagents are packaged in narrow-mouth glass bottles, and a paper-printed bottle sticker B is pasted on the bottle body A. The basic information of the reagent is marked on the bottle sticker B, such as concentration, expiration date, etc. . At the end of pouring the liquid in the bottle, the effect of breaking the liquid at the mouth of the bottle is poor, such as figure 1 As shown, a small amount of reagent liquid C often flows to the bottle body A along the outer edge of the bottle mouth, which causes the bottle sticker B pasted on the bottle body A to...

AI Technical Summary

Problems solved by technology

At the end of pouring the liquid in the bottle, the effect of breaking the liquid at the mouth of the bottle is poor, such as figure 1 As shown, a small amount of reagent liquid C often flows to the bottle body A along the outer edge of the bottle mouth, which causes the bottle sticker B pasted on the bottle body A to be corroded by the reagent. Once the bottle sticker B is corroded and the reagent information is marked The text is illegible, in order to ensure the accuracy of the test, the reagent can only be discarded

[0003] In order to protect the bottle stickers, the experimenters sometimes stick a layer of scotch tape on the surface of the bottle sticker B, and cover the paper bottle sticker B with the scotch tape, so as to reduce the corrosion of the bottle sticker B. Although this method can be used in a certain However, there are still the following problems in the long-term use process: some bottle stickers B have a large area, and sometimes need multiple tapes to be spliced ​​together to completely cover it, which is inconvenient to operate

In addition, because the surface of the tape is often exposed to corrosive reagents, it is easy to age and turn yellow. After the tape turns yellow, the light transmittance will become poor, which will affect the clarity of the information printed on the bottle label B behind it.
