Embodiment 1

[0088] A preparation method of microbial polystyrene particle insulation board is as follows:

[0089] (1) Select the mixed bacteria KJ01 with the function of mineralization deposition, and use liquid medium for inoculation and cultivation. The composition of the liquid medium is: 1 L of ultrapure water, 10 g of tryptone, 5 g of yeast extract, 10 g of sodium chloride, and adjust the pH to 7.0 with 5 mol / L NaOH. After the bacteria were inoculated into the liquid medium, they were placed in a constant temperature shaker, and incubated at 30° C. at a speed of 120 r / min for 24 hours to obtain a bacteria solution.

[0090] (2) Centrifuge the bacteria solution obtained in step (1) for 2 minutes to obtain the bacteria sludge for later use.

[0091] (3) Dilute the bacteria slime obtained in step (2) with distilled water until the OD600 value is 2.0 to obtain the bacteria liquid for later use.

Abstract

The invention discloses a manufacturing method for a microorganism heat-insulation building material. The manufacturing method for the microorganism heat-insulation building material comprises the following steps: taking a bacteria solution which has a mineral deposition function and is prepared from microorganisms and a corresponding nutrient solution as raw materials; directly carrying out mineral deposition on various lightweight aggregates or compounding inorganic or organic cementing materials; and carrying out microorganism inactivation and pore forming to obtain novel microorganism heat-insulation plates, heat-insulation blocks, heat-insulation concrete, heat-insulation mortar and the like. By the method, the physical and mechanical properties of an existing traditional heat-insulation material can further be improved through a microorganism mineralization function and an inactivation process. Microorganism mineral deposition products are used as cementing material manufacturingand modifying building heat-insulation materials, contradiction between strength and heat insulation of the heat-insulation materials can be solved effectively, cementing materials such as cement arereduced and are even prevented from being used, resource consumption are reduced remarkably, mine excavation frequency is reduced, pollution emission is eliminated, and environment stress and haze influence are relieved. The manufacturing method for the microorganism heat-insulation building material is an environmentally friendly building material manufacturing method, and has good economic benefit, environment benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of thermal insulation building materials, in particular to a method for manufacturing microbial thermal insulation building materials. Background technique [0002] Building energy consumption has accounted for more than 35% of the total energy consumption in society, and the use of thermal insulation materials in building envelope structures has become an important means to reduce building energy consumption. Traditional building insulation materials include organic insulation materials such as polystyrene board, extruded board, polyurethane board, etc., and inorganic insulation materials such as rock wool board, expanded perlite board, inorganic insulation mortar, insulation concrete, etc. However, these thermal insulation materials themselves need to consume a large amount of energy in the production and preparation process, causing adverse effects on the environment. For example, in the preparation proc...
