Corrosive liquid reagent bottle sticker protective tape and manufacturing method thereof

Abstract

A protective tape for corrosive liquid reagent bottle stickers and a manufacturing method thereof, relating to the technical field of industrial tapes, comprising an adsorption layer with pores for absorbing corrosive liquid reagents, an adhesive layer is provided on the inner side of the adsorption layer, and an adhesive layer is provided on the outer side of the adsorption layer and The bottom end is provided with a leak-proof layer for preventing the corrosive liquid reagent from seeping out, and the top surface of the adsorption layer is exposed to be in contact with the corrosive liquid reagent, thereby realizing the absorption of the corrosive liquid reagent by the adsorption layer. The corrosive liquid reagent bottle sticker protective tape can be pasted on the bottle neck of the reagent bottle through the adhesive layer. Through the barrier and adsorption of the above protective tape, it can effectively prevent the corrosive liquid reagent from dripping onto the bottle sticker and cause the bottle sticker to be corroded The problem.

Description

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

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.
