Embodiment 1

[0017] A preparation method of a disposable paper cup, comprising the following steps: comprising the steps of:

[0018] S1. After mixing bagasse, polylactic acid, tackifying resin, isobornyl acrylate, ethyl maltol and water, stir, then remove impurities with a double-layer filter to obtain a filtrate;

[0019] S2. After the filtrate is placed, it is squeezed to drain water, and the supernatant liquid is drained to obtain the finely processed raw material; the finely processed raw material is added to the mold, and hot pressed to obtain the initial paper cup mold;

[0020] S3. Use a laminating machine to pour a single-sided polyethylene film on the front of the paper cup primary mold, perform corona treatment on the reverse side of the paper cup primary mold, and then print the required pattern with a printing machine, and then cut the paper cup primary film into fan-shaped sheets and fold it into A circular paper cup body is provided with a fiber cotton layer on the correspon...

Abstract

The invention discloses a preparation method of a disposable paper cup. The preparation method comprises the following steps that S1, bagasse, polylactic acid, tackifying resin, isobornyl acrylate, ethyl maltol and water are mixed and the stirred, and impurities are removed with a double-layer filter net to obtain a filter liquor; S2, after the filter liquor is placed, extrusion and drainage are carried out, a supernatant liquid is drained away to obtain a fine processing raw material; the fine processing raw material is added on a die, and hot pressing is carried out to obtain a paper cup blank mold; S3, a lamination machine is used for spraying single-face polyethylene film on the front face of the paper cup blank mold, corona treatment is carried out on the reverse face of the paper cupblank mold, then a printing machine is used for printing required patterns, the paper cup blank mold is cut into fan-shaped pieces and folded into a circular paper cup body, a fiber cotton layer is arranged on the portion, where the hand holds a cup body, of the thumb and index finger, and the disposable paper cup is obtained. The prepared cup paper has excellent water resistant performance.

Description

technical field [0001] The invention relates to a paper cup, in particular to a preparation method of a disposable paper cup. Background technique [0002] A paper cup is a kind of paper container made by mechanically processing and bonding base paper (white cardboard) made of chemical wood pulp, with a cup-shaped appearance. Waxed paper cups for frozen food, can hold ice cream, jam and butter, etc. Paper cups for hot drinks are coated with plastic, resistant to temperatures above 90°C, and can even be filled with water. Paper cups are characterized by safety, sanitation, lightness and convenience. It can be used in public places, hotels and restaurants, and it is a disposable product. But the water resistance of existing paper cup is not high, can not satisfy the demand of market. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a disposable paper cup. The p...
