Embodiment 1

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

[0044] a. Preparation of yeast protein:

[0045] Get 30Kg of beer fermentation industrial waste yeast cells (the leftovers of beer production, the protein content in its dry matter reaches 45%-55%, and the other components are barley pericarp, seed coat and barley mixed with yeast through yeast fermentation) hop fragments, etc.), diluted with cold water at 5°C, and the amount of water added was 3.5 times the weight of the yeast cells of beer fermentation industrial waste; once passed through an 80-mesh sieve, 80% of the impurities could be removed, and then sieved with a 100-mesh sieve Once, all visible impurities can be removed to obtain the crude product filtrate; stand still for 30 minutes to allow automatic precipitation, and pour out the supernatant liquid; take 4 times the weight of the lower material at 10 ℃ sterile water for 3 times to wash the lower material, a...

Embodiment 2

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

[0054] a. Preparation of yeast protein:

[0055] Peel the potatoes, add twice the amount of water of the weight of the peeled potatoes, boil for 30-50min, filter and remove the potato dregs, add 2-2.5 times the volume of distilled water in the filtrate, and add 1-5% (percentage by weight, The same as in the following) to obtain liquid culture medium, and sterilize, get a ring of slanted brewer's yeast strain, inoculate in the liquid culture medium of 5-20ml, inoculum size (breer's yeast strain ratio liquid medium mass ratio) is 0.2-2%, culture temperature 20-35 ℃, culture time 40-70h, pH value 4.5-6, obtain yeast seed liquid, standby; Composition and weight percentage ratio is 5-10% refined flour, 1-5% Glucose, 0.01-0.05% epigermose, 0.01-0.02% ammonium sulfate, 0.01-0.02% potassium chloride, and 85-93% soybean juice are mixed to prepare a solid medium, and yeast seed ...

Embodiment 3

[0064] A preparation method for yeast cell protein concrete foaming agent, comprising the following steps:

[0065] a. Preparation of yeast protein:

[0066] Peel the potatoes, add twice the amount of water of the weight of the peeled potatoes, boil for 30-50min, filter and remove the potato dregs, add 2-2.5 times the volume of distilled water in the filtrate, and add 1-5% (percentage by weight, The same as in the following) to obtain liquid culture medium, and sterilize, get a ring of slanted brewer's yeast strain, inoculate in the liquid culture medium of 5-20ml, inoculum size (breer's yeast strain ratio liquid medium mass ratio) is 0.2-2%, culture temperature 20-35℃, culture time 40-70h, pH value 4.5-6, get the yeast seed liquid, spare; the composition and weight percentage ratio is 5-10% refined flour, 1-5% Glucose, 0.01-0.05% epigermose, 0.01-0.02% ammonium sulfate, 0.01-0.02% potassium chloride, and 85-93% soybean juice make a solid medium, and get yeast seed liquid (ac...

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 "light weight and high strength", foam concrete, with its outstanding advantages (light weight; good thermal insulation performance, thinner walls, increased building area; small foundation load, strong earthquake resistance; sound insulation; Insulation, heat insulation; self-leveling, self-compacting of mixed pulp, good construction workability, good compatibility with other building materials, autoclaved maintenance, good processing performance, etc.), has become a new type of vigorously promoted Building material wall material. However, the existing foamed concrete has the disadvantages of low strength, unstable quality, and high cost. The foaming agent with excellent performance a...
