Abstract

The invention discloses a high-quality disposable paper cup and a preparation method thereof. It is made of the following substances in parts by weight: 30-35 parts of bagasse, 40-50 parts of reed, 20-25 parts of Chinese herbal medicine residue, 3-5 parts of modified Atmospheric powder, 8-10 parts of corn starch, 15-20 parts of surface spraying agent; the preparation method has the following steps: (1) pulping, (2) pulping, (3) copying, (4) surface treatment, ( 5) Make a cup. The raw materials of the disposable paper cup of the present invention are easy to obtain and convenient to obtain, and can be completely degraded under natural conditions, which not only solves the problem of environmental pollution, but also reasonably turns waste from traditional Chinese medicine into treasure, saving waste treatment costs for the factory. The paper cup has Good water resistance, heat resistance, certain antibacterial function, low cost, simple manufacture, and good promotion value.

Example Embodiment

[0025] Example 1
[0026] A preparation method of a high-quality disposable paper cup is made of the following substances in parts by weight:
[0027] 30 parts of bagasse, 45 parts of reed, 20 parts of Chinese herbal medicine residue, 3 parts of modified attapulgite powder, 10 parts of corn starch, 15 parts of surface spraying agent;
[0028] Its preparation method is:
[0029] (1) Pulping: Put 30 parts of bagasse, 45 parts of reeds, and 20 parts of Chinese herbal medicine residues in a mechanical beater to prepare pulp for later use;
[0030] (2) Sizing: add 3 parts of modified attapulgite powder and 10 parts of corn starch to the slurry water for slurry processing;
[0031] (3) Paper making: paper semi-finished products are obtained after pulp water is copied by a paper machine;
[0032] (4) Surface treatment: Spray 15 parts of surface spraying agent on one side of the paper, and print patterns and texts on the other side;
[0033] (5) Cup making: Die-cut the treated paper and send it to the cup making machine to make cups to get the finished product.
[0034] Further, the Chinese herbal medicine residues are composed of licorice residues, fragrant tea vegetable residues, and Atractylodes macrocephala residues, with a mass ratio of 3:2:1.
[0035] Further, the modified attapulgite powder is obtained by ion-exchanging the attapulgite with saturated sodium chloride, and then organically modifying the attapulgite with octadecyltrimethylammonium chloride.
[0036] Further, the surface spraying agent is formed by adding 23 parts of modified pea starch, 35 parts of polyvinyl alcohol, and 5 parts of orange peel pectin into 230 parts of hot water and stirring until homogeneous.
[0037] Further, the modified pea starch is an anionic derivative obtained by reacting natural pea starch and sodium tripolyphosphate through dry heat.
[0038] Further, the temperature of the hot water is 85-90°C.
