preparation example Construction

[0030] Such as figure 1 As shown, the preparation method of the fungus-based biomass packaging material with corn stalks as the main ingredient provided by the embodiment of the present invention includes the following steps:

[0031] S101: Preparation of compost: Mix 65-85 parts of corn stalks, 5-15 parts of palm silk, and 10-20 parts of biomass packaging material additives; add 1.0 times the dry weight of materials to the compost- 1.25 times tap water, mix well, adjust the water content in the culture material to 55%-60%, then put it into a sterilization bag, and sterilize it on the tunnel microwave sterilization equipment for 10 minutes-20 minutes.

[0032] S102: Pre-cultivation of strains: Inoculate the solid microbial strains into bacteria bags cooled to room temperature according to 15%-20% (w / w) of the wet weight of the culture material, mix well, tie the bags, and place them at a temperature of 25°C- Cultivate for 7 days to 11 days in a dark culture room at 30°C, ambi...

Embodiment 1

[0038] The preparation method of the fungus-based biomass packaging material with corn stalks as the main material provided by the embodiment of the present invention, the specific steps are:

[0039] (1) Preparation of compost: Mix 70 parts of corn stalks, 15 parts of palm silk, and 15 parts of biomass packaging material additives; The water content is 60%, then put into a sterilization bag, and sterilize on the tunnel type microwave sterilization equipment for 12 minutes.

[0040] Corn stalks are corn stalks that have undergone dehulling treatment, with a diameter of 5-30mm, and the mass fractions of corn stalks with lengths of 5-10mm, 10-17mm, and 17-30mm are 65%, 17%, and 18% respectively. %. The length of palm silk is 20-40mm, of which, the mass fraction of palm silk with a length of 20-30mm and 30-40mm is 78% and 22% respectively; corn stalks and palm silk require freshness, no mildew, and Moisture content is less than 10%.

Abstract

The invention relates to a fungus-based biomass packaging material taking maize straw as main materials and a preparation method thereof. The biomass packaging material comprises the maize straw, palm threads and biomass packaging material additives, wherein the biomass packaging material additives comprise the following components in parts by mass: 60 parts of rice bran, 8 parts of maize flour, 8 parts of soybean meal, 6 parts of flour, 10 parts of quick lime and 8 parts of gypsum powder. The preparation method comprises the following steps: preparing a culture material; pre-culturing strains; filling mold and culturing; and drying samples. The preparation method is simple in production process and low in production cost; the prepared biomass packaging material is environmentally friendly and ecological, has excellent biodegradable property and excellent mechanical property, is capable of effectively reducing environmental pollution, and is an ideal environment-friendly packaging material.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly biomass packaging materials, and in particular relates to a fungus-based biomass packaging material with corn stalks as the main material and a preparation method thereof. Background technique [0002] Entering the 21st century, with the continuous development of the global economy, the annual consumption of packaging materials in the world exceeds 800 billion US dollars. It can be seen that packaging has become an indispensable part of commodity sales and world trade. According to the statistics of relevant departments, from 2011 to 2015, the total output value of my country's packaging industry reached 600 billion yuan, and now it is growing at an average rate of 6% every year, becoming the second largest country in the packaging industry after the United States. At this stage, most of the packaging materials used in my country are mainly synthetic materials such as polystyrene (EP...
