Embodiment Construction
[0026] The present invention will be further explained below in conjunction with specific embodiments.
[0027] refer to figure 1 , embodiment one
[0028] In this example, a method for preparing a high-temperature-resistant, high-water-resistant, anti-deformation paper container is proposed, and base paper and modified materials are prepared, and the following steps are adopted:
[0029] S1: Prepare No. 1 batching hopper, No. 1 finishing hopper, No. 2 batching hopper, No. 2 finishing hopper, multi-layer headbox and sizing equipment;
[0030] S2: According to the mass percentage, 56 parts of polylactic acid are obtained and heated to 50 ℃ ~ 80 ℃, add 4 parts of chitosan, 3 parts of microcrystalline cellulose and 2 parts of sodium pyrophosphate dispersant, and use ultrasonic equipment Stir after treatment to prepare an additive solution. First prepare the polylactic acid into a 5% to 10% aqueous solution before heating, then heat the polylactic acid solution to 50°C to 80°C, ...

Abstract
The invention belongs to the field of food packaging, particularly relates to a preparation method of a high-temperature-resistant, high-water-resistant and anti-deformation paper container, and provides the following scheme aiming at the problems that an existing paper container is not resistant to high temperature, poor in water resistance, poor in oil resistance and prone to deformation. The method comprises the following steps that a first batch hopper, a first forming hopper, a second batch hopper, a second forming hopper, a multi-layer headbox and sizing equipment are prepared, chitosan, microcrystalline cellulose and lactitol are used for improving the oil resistance of paper, high-temperature-resistant powder is used for improving the high-temperature-resistant capacity of a paper container, the paper is prevented from becoming brittle, and the paper container is made of paper. A waterproof film can be formed on the surface of the paper container through the surface sizing liquid, the waterproof capacity of the paper container is enhanced, the paper container has the advantages of high temperature resistance, water resistance and oil resistance, meanwhile, a double-layer structure is adopted, strength is high, toughness is good, impact resistance is achieved, stability is high, and the manufactured paper container is not prone to deformation.
Description
technical field [0001] The invention relates to the technical field of food packaging, in particular to a method for preparing a paper container with high temperature resistance, high water resistance and deformation resistance. Background technique [0002] Containers made of paper, especially paper containers used to accommodate food and beverages, are widely available in the market, such as beverage cups and food boxes in Western-style fast food, cups in milk tea shops, etc. For example, the patent application number CN201710184412.9 discloses A non-wood natural color paste food packaging paper and a preparation method thereof, which are safe and environmentally friendly, maintain the natural color of plant fibers, are dust-free and dust-free, and do not produce harmful substances in the papermaking process, reduce the cost of waste water treatment, and have low production costs The advantages. [0003] But this a kind of non-wood type natural color paste food wrapping p...
