Embodiment 1

[0018] The invention provides a technical solution: a method for preparing starch foamed disposable tableware and packaging products. The ingredients are divided into: starch (corn starch or tapioca starch) 45%-59%; fiber (various fibers) 4%-6%; bioplastic 3%-5%; zinc stearate 0.5%-2%; accelerator 1%-2%; water 25%-45%;

[0019] The preparation method is as follows: raw materials are weighed according to the proportion → low-speed and high-speed stirring by the mixer → molding product by injection molding machine → drying treatment → waterproof treatment product packaging;

[0020] Among them, the raw materials are weighed in proportion: the starch, fiber, bioplastic, zinc stearate and accelerator are loaded according to the selected proportion;

[0021] Mixer at low speed and high speed: stir the fibers at high speed, add starch and other auxiliary materials, add water in proportion, run the mixer at a low speed of 200 rpm for 2 minutes, and then turn to high speed and mix at ...

Embodiment 2

[0028] According to the percentage system, the ingredients are divided into: starch 50%-60%; vegetable powder 15%; bioplastic 3%-5%; zinc stearate 0.5%-2%; accelerator 1%-2%; water 13%-20% %, others are identical with embodiment 1.

Abstract

The invention discloses starch foamed disposable tableware and a preparation method of a packaging product. The starch foamed disposable tableware comprises the following components in percentage: 45-59% of starch (corn starch or cassava starch), 4%-6% of fibers (various fibers), 3%-5% of bioplastic, 0.5%-2% of zinc stearate, 1%-2% of an accelerant, and 25%-45% of water. The preparation method comprises the following steps: weighing the raw materials in proportion; stirring by a stirrer at low speed and high speed; forming a product by an injection molding machine; drying the product; performing water repelling treatment; and packaging the final product. According to the invention, the starch foamed disposable tableware and the preparation method have the beneficial effects that the starchis adopted as a main preparation component, so that no harm is caused to a human body, environment-friendly treatment is facilitated after the disposable tableware is discarded, and the degradation speed is high.

Description

technical field [0001] The invention relates to the technical field of starch foam preparation, in particular to a preparation method of starch foam disposable tableware and packaging products. Background technique [0002] Foamed tableware, that is, disposable foamed plastic tableware, refers to polystyrene resin as raw material, which is heated and melted at high temperature in an extruder and then extruded with a foaming agent (butane) to pull the sheet. After winding, place it in a ventilated and humid environment for health preservation, and then perform secondary heating and blister molding to make various tableware such as fast food boxes, soup bowls, instant noodle bowls, fresh food trays, etc. However, this kind of foamed tableware is toxic during use and is a banned product in the country. Hereby, our company has developed a method for preparing starch-foamed disposable tableware and packaging products. Starch is used as the main preparation ingredient, which is ha...
