Problems solved by technology

Most of the existing fast food is made of polypropylene (PP) material. With the increase of the consumption, the phenomenon of white pollution becomes serious. Plastic pollution, orderly prohibit and restrict the production, sale and practical use of some plastic products, and actively promote recyclable and easily recyclable degradable alternative products
[0003] As an upgraded product of plastic tableware, starch-based materials are usually used to replace some plastic materials. It is acceptable to use starch-based tableware to prepare ordinary tableware, but when low temperature (-18°C) freshness is required, conventional starch-based lunch boxes are used. , the lunch box becomes hard and brittle, and is easily damaged during handling; and after microwave heating, the strength of the lunch box becomes lower and cannot be used normally
[0004] Chinese patent CN 106496652A discloses a starch-foamed disposable tableware, which consists of 86-93 parts by weight of modified corn starch, 0.8-1.2 parts by weight of zinc stearate release agent, and 0.2-0.4 parts by weight of accelerator Potassium sorbate, 1.5 to 2 parts by weight of thickener sodium polyacrylate, 45 to 53 parts by weight of stabilizer, and several parts by weight of water are mixed and stirred to obtain the mixture, and then obtained by hot pressing, although the invention adopts a relatively A large amount of cornstarch is used as a raw material to reduce costs and is safe and environmentally friendly. However, the disposable tableware made from it does not have frost resistance. It becomes hard and brittle after low-temperature freezing, and the hardness becomes poor after heating. It can only be used as ordinary tableware. Used in trains, high-speed rail and other fast food industries that require low-temperature freezing and fresh-keeping transportation

Abstract

The invention relates to a starch-based tableware with antifreeze and microwave resistance and a preparation method thereof. Propylene maleic anhydride and polyolefin elastomer are mixed and granulated. The anti-freeze and microwave-resistant starch-based tableware of the present invention has good anti-freeze performance, good toughness, is not easy to be damaged, is resistant to microwave heating, and has good strength, and is suitable for fast food industries such as trains and high-speed rails that require low-temperature freezing and fresh-keeping transportation.

Description

technical field [0001] The invention belongs to the technical field of tableware materials, and in particular relates to a frost-resistant and microwave-resistant starch-based tableware and a preparation method thereof. Background technique [0002] Trains, high-speed rail, etc. are uniformly equipped with the fast food industry. The fast food made is kept fresh at low temperature, transported, and heated by microwave before eating. This requires the fast food box material to have good frost resistance, good toughness, not easy to be damaged, and resistant to microwave heating. Strength nice features. Most of the existing fast food is made of polypropylene (PP) material. With the increase of the consumption, the phenomenon of white pollution becomes serious. For plastic pollution, orderly prohibit and restrict the production, sale and practical use of some plastic products, and actively promote recyclable and easily recyclable degradable alternatives.
