Embodiment 1

[0043] A preparation method of yeast cell protein concrete foaming agent, including the following steps:

[0044] a. Preparation of yeast protein:

[0045] Take 30Kg of beer fermentation industrial waste yeast cells (which are leftovers of beer production, and the protein content of its dry matter reaches 45%-55%. The other components are barley peels, seed coats, and seed coats that are mixed with yeast through yeast fermentation. Hop fragments, etc.), diluted with cold water at 5°C, and the amount of water added is 3.5 times the weight of the yeast cell of the beer fermentation industry waste; pass through an 80 mesh sieve once to remove 80% of the impurities, and then sieve with a 100 mesh sieve One time, all visible impurities can be removed to obtain a crude filtrate; stand still for 30 minutes to allow automatic precipitation and pour out the upper clear liquid; take 4 times the weight of the lower material at 10℃ sterile water 3 times to rinse the lower material, and then us...

Embodiment 2

[0053] A preparation method of yeast cell protein concrete foaming agent, including the following steps:

[0054] a. Preparation of yeast protein:

[0055] Cut the potatoes, add twice the weight of the peeled potatoes, boil for 30-50 minutes, filter to remove the potato residues, add 2-2.5 times the volume of the filtrate to the filtrate with distilled water, and add 1-5% (weight percentage, The same hereinafter) glucose to obtain a liquid medium, and sterilize it, take a ring of slant beer yeast strains, inoculate it in 5-20ml of liquid medium, the inoculation amount (the mass ratio of beer yeast strains to liquid medium) is 0.2-2%, cultivation temperature 20-35℃, cultivation time 40-70h, pH value 4.5-6, get yeast seed liquid, ready for use; set the composition and weight percentage to 5-10% refined flour, 1-5% Dextrose, 0.01-0.05% epitose, 0.01-0.02% ammonium sulfate, 0.01-0.02% potassium chloride, and 85-93% soybean juice mixed to prepare a solid medium, and yeast seed liquid (...

Embodiment 3

[0064] A method for preparing a yeast cell protein concrete foaming agent includes the following steps:

[0065] a. Preparation of yeast protein:

[0066] Cut the potatoes, add twice the weight of the peeled potatoes, boil for 30-50 minutes, filter to remove the potato residue, add 2-2.5 times the volume of the filtrate to the filtrate with distilled water, and add 1-5% (weight percentage, The same hereinafter) glucose to obtain a liquid medium, and sterilize it, take a ring of slant beer yeast strain, inoculate it in 5-20ml liquid medium, the inoculation amount (the ratio of beer yeast strain to liquid medium mass) is 0.2-2%, cultivation temperature 20-35℃, cultivation time 40-70h, pH value 4.5-6, get yeast seed liquid, ready for use; set the composition and weight percentage to 5-10% refined flour, 1-5% The solid medium is prepared from glucose, 0.01-0.05% epitose, 0.01-0.02% ammonium sulfate, 0.01-0.02% potassium chloride, and 85-93% soybean juice. The yeast seed liquid (accoun...

Abstract

The invention relates to a yeast protein concrete foaming agent and a preparation method thereof. The preparation method comprises the following steps: separating yeast protein from beer, wine and soy sauce fermentation industrial waste, or preparing the yeast protein by steps of inoculation, culture, impurity and odor removal, centrifugal precipitation and the like, adding NaOH or Ca(OH)2 aqueous solution, mixing in a reaction kettle, hydrolyzing at a temperature of between 50 and 100 DEG C for 3 to 6 hours, and filtering to prepare mother solution of a yeast protein foaming agent; and compounding and evenly mixing according to a weight ratio of the mother solution of the yeast protein foaming agent to a stabilizing agent to a dispersing agent to a preservative to water being 50-150:1-6:5-10:0.1-1:10-50 to prepare the concrete foaming agent. The foaming agent has the advantages of low price, good environmental protection, excellent foaming performance, and easily obtained raw materials or easy mass production; and prepared foam concrete has light weight and heat insulation, and meets the requirement of an energy-saving wall on the performance of the foam concrete.

Description

Technical field [0001] The invention belongs to a concrete foaming agent and a preparation method thereof, and relates to a yeast cell protein concrete foaming agent and a preparation method thereof. Background technique [0002] With the development of building materials in the direction of "lightweight and high strength", foam concrete has its outstanding advantages (light weight; good thermal insulation performance, thinner walls, and increased building area; low foundation load, strong earthquake resistance; sound insulation; Heat preservation and heat insulation; the mixed slurry is self-leveling and self-compacting, has good construction and workability, has good compatibility with other building materials, and has the advantages of autoclave-free curing and good processing performance), becoming a new type of vigorous promotion Building materials wall materials. However, the existing foam concrete has disadvantages such as low strength, unstable quality, and high cost. T...
