Embodiment Construction

[0019] The method for preparing cushioning packaging materials from agricultural waste provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020]

[0021] In this embodiment, the method for preparing cushioning packaging materials from agricultural wastes includes the following steps:

[0022] Step 1: Pulverize the composition of 2kg cotton husk, bran, rice husk and corn cob, sieve out large debris, then soak and wash, remove the washed composition, put it in an autoclave, and heat up to 128 °C, cook and sterilize at 2 atmospheric pressure, the cooking time is 100min, cool the composition after cooking, and then add lime water to adjust the pH to 7;

[0023] Step 2, put the composition with a pH value of 7 obtained in step 1 into a blender, add 100 g of the culture solution containing Pleurotus eryngii mycelia, stir evenly with a blender, and obtain the agricultural waste composition and Pleurotus eryngii cultu...

Abstract

The invention provides a method for preparing a cushion packing material by using agricultural wastes. The method comprises the following steps: S1, grinding the agricultural wastes, putting into a high-pressure kettle, heating to the temperature between 110 and 140 DEG C, stewing and sterilizing under 2 to 3 times atmospheric pressure for 60 to 120 minutes, cooling, and adding whitewash to adjust pH to 6-8; S2, adding 60 to 97 mass parts of agricultural wastes into 3 to 40 mass parts of fungus-containing nutrient solution, and uniformly stirring; S3, fill the mixture obtained in the step 2 into a cushion packing material mold, placing in a dark room at the temperature between 23 and 28 DEG C, standing hypha of fungus for 5 to 7 days; S4, heating the dark room to the temperature of 4 to 5 DEG C, and sterilizing the mixture-containing mold by using ultraviolet light for 30 to 60 minutes, thus obtaining the cushion packing material; and S5, demolding the cushion packing material.

Description

technical field [0001] The invention relates to the field of preparation of packaging materials, in particular to a method for preparing biological self-assembled cushioning packaging materials by using agricultural waste. Background technique [0002] Expandable polystyrene (EPS) foam products have become the first choice for packaging materials and shockproof linings due to their superior packaging performance and low price. However, EPS foam plastic cushioning packaging materials cannot be decomposed under natural conditions, causing serious pollution to the environment. At present, Europe, the United States, Japan, South Korea, Australia and other regions and countries have legislated to prohibit the import of EPS-packaged industrial products, or raise environmental protection taxes several times to restrict and eliminate the import of foamed plastic packaging materials as packaging products, forming the so-called " green trade barrier". According to the statistics of ...
