preparation example 1

[0076] The modification method of starch modified sepiolite is:

[0077] Configure 2wt% tapioca starch solution, gelatinize at 80°C for 70min, use 0.1M NaOH solution to adjust the pH of the gelatinized starch solution to 10.5, add acetic acid to the solution, the mass ratio of tapioca starch to acetic acid is 1:0.5, and the starch Heat the mixture with acetic acid at 90°C for 30min; add the above-mentioned heated mixture into 120g / L sepiolite aqueous suspension, stir at 80°C for 15min, adjust the pH of the solution to 2 with 2M HCl solution, and finally wash with water Precipitate to neutrality and dry to obtain starch-modified sepiolite.

preparation example 2

[0079] The modification method of starch modified sepiolite is:

[0080] Configure 5wt% tapioca starch solution, gelatinize at 90°C for 50min, use 0.3M NaOH solution to adjust the pH of the gelatinized starch solution to 11.5, then add acetic acid to the solution, the mass ratio of tapioca starch to acetic acid is 1:2, and the starch Heat the mixture with acetic acid at 80°C for 60min; add the above-mentioned heated mixture into 160g / L sepiolite aqueous suspension, stir at 90°C for 10min, adjust the pH of the solution to 3 with 1M HCl solution, and finally wash with water Precipitate to neutrality and dry to obtain starch-modified sepiolite.

preparation example 3

[0082] The modification method of starch modified sepiolite is:

[0083] Prepare 3wt% cassava starch solution, gelatinize at 85°C for 60min, use 0.2M NaOH solution to adjust the pH of the gelatinized starch solution to 11, then add acetic acid to the solution, the mass ratio of tapioca starch to acetic acid is 1:1, and the starch Heat the mixture with acetic acid at 85°C for 45min; add the above-mentioned heated mixture into 140g / L sepiolite aqueous suspension, stir at 85°C for 13min, use 1.5M HCl solution to adjust the pH of the solution to 2.5, and finally use water The precipitate was washed to neutrality and dried to obtain starch-modified sepiolite.

Abstract

The invention discloses an antibacterial paper cup and a production method thereof. The paper cup comprises a cup body, and the cup body comprises a first antibacterial layer, a second antibacterial layer and a middle layer arranged between the first antibacterial layer and the second antibacterial layer; a laminating layer is arranged on one side, far from the middle layer, of the first antibacterial layer or the second antibacterial layer; each of the first antibacterial layer and the second antibacterial layer is prepared from the following components: bamboo fibers, konjac glucomannan, starch modified sepiolite and a dispersing agent; the middle layer is prepared from the following components: plant fiber pulp, nano silicon nitride, starch modified sepiolite and a dispersing agent; and the laminating layer is prepared from the following components: silicate silver-loaded antibacterial powder, low-density high-pressure polyethylene and nano zinc oxide. The paper cup produced through the method is of a four-layer structure, the paper cup can be endowed with a good and lasting antibacterial effect through first antibacterial layer slurry, second antibacterial layer slurry and laminating layer slurry, and the paper cup can be endowed with good strength and stiffness through the middle layer.

Description

technical field [0001] The application relates to the field of paper cups, in particular to an antibacterial paper cup and a production method thereof. Background technique [0002] Disposable paper cups are essential supplies in people's daily life, especially in the catering industry, where the usage of disposable paper cups is very large. At present, most of the ordinary paper cups on the market are made by mechanically processing base paper (white cardboard) made of chemical wood pulp and covered with a layer of polyethylene plastic film. Consuming a lot of wood is not conducive to sustainable development, and paper cups have poor antibacterial properties. If the paper cups are not used for a long time after production, bacteria will grow on the cup body, which will affect the health of users. Contents of the invention [0003] To solve the problem of poor antibacterial performance of paper cups in the related art, the present application provides an antibacterial pap...
