Embodiment 1

[0017] figure 1 A preparation method of a laboratory reagent bottle label protective film is shown, comprising the following steps:

[0018] S1. Take a 1500ml beaker, add 500g deionized (above grade 2 water standard, total mass is 850g), 100g water-based flame retardant treatment agent (no model limit, preferably transparent). Stir in a water bath at 80°C to dissolve the water-based flame retardant treatment agent (stirring speed 200r / min), then add 14g triethanolamine (analytical grade), 4g stearic acid (analytical grade), 0.1g isothiazolinone (commercial grade) (Sold), water bath at 85°C with stirring, heating and stirring, so that the above substances are completely dissolved under heating and stirring, and this hot solution is solution A.

[0019] S2. Take a 100ml beaker, 20g white candle (commercially available), heat to melt the white wax into a liquid (water bath 82°C, after melting, use tweezers to pick out the residual wax core or remove the wax core in advance), pou...

Embodiment 2

[0022] A preparation method of a laboratory reagent bottle label protective film, comprising the following steps:

[0023] S1. Take a 1500ml beaker, add 500g deionized (above grade 2 water standard, total mass is 900g) and 100g water-based flame retardant treatment agent (BC-1018 transparent). Stir at 82°C in a water bath to dissolve the water-based flame retardant treatment agent (stirring speed 200r / min), then add 14g triethanolamine (analytical grade), 4g stearic acid (analytical grade), 0.1g isothiazolinone (commercial grade) (Sold), stir, heat and stir in a water bath at 85°C, so that the above substances are completely dissolved under heating and stirring, and this hot solution is solution A.

[0024] S2. Take a 100ml beaker, 20g white candle (commercially available), heat to melt the white wax into a liquid (water bath 85°C, use tweezers to remove the residual wax core after melting or remove the wax core in advance), pour solution A while it is still hot, and continue ...

Embodiment 3

[0030] A preparation method of a laboratory reagent bottle label protective film, comprising the following steps:

[0031] S1. Take a 1500ml beaker, add 500g of deionized water (above the standard of secondary water, the total mass is 876g), and 100g of water-based flame retardant treatment agent. Stir at 85°C in a water bath to dissolve the water-based flame retardant treatment agent (stirring speed 200r / min), then add 14g triethanolamine (analytical grade), 4g stearic acid (analytical grade), 0.1g isothiazolinone (commercial grade) (Sold), water bath at 85°C with stirring, heating and stirring, so that the above substances are completely dissolved under heating and stirring, and this hot solution is solution A.

[0032] S2. Take a 100ml beaker, 20g white candle (commercially available), heat to melt the white wax into a liquid (water bath 89°C, use tweezers to remove the residual wax core after melting or remove the wax core in advance), pour solution A while it is still hot...

Abstract

The invention discloses a preparation method of a laboratory reagent bottle label protective film, and relates to the technical field of label protective films. Putting the water-based flame-retardant treatment agent into deionized water, and heating in a water bath to fully dissolve the water-based flame-retardant treatment agent; triethanolamine, stearic acid and isothiazolinone are added, and water bath heating and stirring are continued; heating to melt the white wax, and pouring the white wax while hot; and adding boiling deionized water, heating and stirring until the substances are completely dissolved, taking down, standing, naturally cooling to room temperature, covering and storing in a glass container to obtain a prepared finished product. The water-based flame-retardant treating agent is used as a raw material of the label protective film, so that the prepared finished product has good fireproof performance; isothiazolinone is added, so that the prepared protective film has a mildew-proof effect; and stearic acid and triethanolamine are added, so that the raw materials are more fully dissolved and emulsified, and the finished product is more uniform. And the prepared finished product is uniform in film formation, fast in film formation and convenient to manufacture, meets the requirements of green chemistry, and has obvious economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of label protective films, in particular to a preparation method of a label protective film for laboratory reagent bottles. Background technique [0002] Labels are widely used in physics, chemistry, biology, medical care, education and other fields, as well as in factories, mines, pilot bases and other industries. Among them, the most widely used are laboratories, especially reagent bottles. Almost every reagent bottle needs to use labels. The contained reagents are marked for easy identification by the operator. The label is usually pasted on the outer wall of the reagent bottle with a self-adhesive label paper on one side, but the label is easy to glue over time, and the surface of the label will also be stained with other reagents or dyes during use, which will cause the text on it to be blurred. Exposure to moisture or high temperatures in reagent vials can also accelerate label deterioration. The cur...
