Abstract

The invention belongs to the field of recycling of agricultural wastes, and particularly relates to a disposable oil-proof water-proof degradable meal box prepared from straws and a preparation method of the meal box. The disposable oil-proof water-proof degradable meal box prepared from the straws is prepared from the following raw materials in parts by weight: 50-100 parts of corn straws, 50-100 parts of wheat straws, 50-100 parts of purple perilla straws, 50-100 parts of bamboo leaves, 1-7 parts of auxiliary agents, 0.5-2.5 parts of oil-proof agents and 0.5-2.5 parts of paraffins. The disposable oil-proof water-proof degradable meal box prepared from the straws, which is disclosed by the invention, has the advantages of good oil proofing and water resistance of a product, simple preparation process, low production cost, degradability and safety without toxicity.

Description

technical field [0001] The invention belongs to the field of agricultural waste recycling, and in particular relates to a disposable oil-proof and waterproof degradable lunch box prepared from straw and a preparation method thereof. Background technique [0002] Straw fiber is one of the huge regenerative biopolymer resources in nature. The annual output of straw fiber in the world is about 40×10 tons, and the annual output of straw resources in China reaches 790 million tons. People pay more and more attention to the huge waste of resources and serious environmental pollution caused by burning or burying straw. At present, there have been many reports on the utilization of straw, such as fertilizer, new energy, animal feed, degradable material, base material for cultivating edible fungi, and building material. [0003] There is no report on the disposable oil-proof and waterproof degradable lunch box prepared by straw. Contents of the invention [0004] In order to solv...
