preparation example Construction

[0039] Such as figure 1 As shown, the preparation method of the fungal-based biomass fireproof material with corn stalks as the main ingredient provided by the embodiment of the present invention includes the following steps:

[0040] S101: Preparation of compost: Mix 30-65 parts of corn stalks, 10-20 parts of sawdust, 10-20 parts of wheat bran and 15-30 parts of biomass fireproof material additive; 1.0-1.25 times the dry weight of the material, tap water, mix well; adjust the water content in the culture material to 55%-60%, and adjust the pH of the culture material to 7-8 at the same time;

[0041] S102: Sterilization treatment: put the culture material into a sterilization bag, and sterilize it on the tunnel microwave sterilization equipment for 10 minutes to 20 minutes;

[0042] S103: Inoculation and cultivation: the culture raw materials to be sterilized are cooled to room temperature, and the solid fungal strains for production are inoculated in the culture raw material...

Embodiment 1

[0047] The specific steps for providing the fungal-based biomass fireproof material with corn stalks as the main ingredient in the embodiment of the present invention are as follows:

Abstract

The invention relates to a fungi-based biomass fireproof material with cornstalk as a main material and a preparation method thereof. The fireproof material is composed of the following ingredients (by weight): 30-65 parts of cornstalk, 10-20 parts of weed tree sawdust, 10-20 parts of wheat bran and 15-30 parts of a biomass fireproof material additive. A preparation method of the material comprises the following steps: preparation of a culture medium; sterilization treatment; and inoculated culture. By using biomass materials such as cornstalk and the like as raw materials and by the utilization of rapid growth of fungal hypha and strong kink force of mycelium, the biomass materials such as cornstalk and the like are converted into an environment-friendly biomass fireproof material. The preparation method of the biomass thermal insulation material is simple; production cost is low; and the product has good strength, good compactness and good fireproof performance. The material of the invention is an environment-friendly biomass fireproof material with market prospect and potential.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly biomass fireproof materials, and in particular relates to a fungus-based biomass fireproof material with corn stalks as the main material and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the large space buildings in modern cities are gradually increasing, which requires fireproof materials in parts of the buildings, and fireproof materials are also required for interior decoration. The fire prevention of building interior decoration is directly related to the safety of people's lives and property. For example, in the early morning of December 5, 2009, a fire accident occurred in the "Lame Horse" nightclub in Perm, the capital of Perm Krai, Russia, killing more than 100 people. People, the interior of the building was decorated with a lot of combustible materials. At present, cellophane, compressed board, density board, foam bo...
