Abstract
The invention discloses a yolk cement concrete foamer and light-weight foaming cement concrete, which comprises the following steps: 1) blending cement, ceramic micro-powder and water evenly according to certain quality; making cement concrete slurry; 2) blending yolk, stabilizer, disperser, conservative and water according to certain weight rate; forming even compact seal-pore foam; weighing certain bulk of foam to add into the cement concrete slurry; stirring evenly; casting; mounding; curing.
Description
(1) technical field
The present invention relates to a kind of light foaming concrete, particularly a kind of egg yolk cement foaming agent and lightweight foaming cement concrete thereof.
(2) background technology
The output of the annual egg of China ranks first in the world greatly about 4,000 ten thousand tons.Egg is as nutriment common in the daily life, and it is rich in necessary nutritive substance---the protein that a large amount of human bodies grows, and in egg most of protein from egg yolk.Contain 15% protein in the egg yolk approximately.Just because of it contains protein foaming composition, be widely used in the food product foaming.
Present domestic foamed concrete goods many with synthetic tensio-active agent, vegetable-protein whipping agent, animal protein foaming agent as the concrete whipping agent of foamed cement.Synthetic tensio-active agent such as Gum Rosin, AES, alkylbenzene sulfonate etc., these whipping agent lathering properties are good, but the froth stability that forms is poor, poor toughness, and mostly be the synthetic product, production cost is higher, the toughness deficiency of whipping agent when preparation foamed cement concrete segment, and mould easily collapses.The vegetable-protein whipping agent mainly is to get cake slag remaining behind its starch or the oily thing and extract with plant seed at present, this type of cake residue protein matter content height, by extracting, hydrolysis, can be made into whipping agent after concentrating, but because present domestic protein fodder scarcity, this type of is used to extract proteinic cake slag and is used for foodstuff additive and fodder additives more.Animal protein foaming agent is to form by sodium hydroxide hydrolysis with things such as animal hair, tellurium, angles, and its raw materials cost is high, and the technology of preparation animal protein foaming agent is still immature, makes to use to be subjected to certain restriction.And will have a large capacity and a wide range, egg yolk that raw material is easy to get is as whipping agent, and be applied to the light foaming concrete goods and do not appear in the newspapers as yet.
(3) summary of the invention
For not enough in the performance that solves existing cement blowing agent product and the technology, one of purpose of the present invention provides a kind of cement concrete whipping agent with the egg yolk preparation.
Two of purpose of the present invention is to provide a kind of lightweight foaming cement concrete with the preparation of egg yolk cement concrete foamer.
The present invention realizes by following measure:
A kind of egg yolk cement concrete foamer, be to be mixed and made into by following materials of weight proportions, yolk: stablizer: dispersion agent: sanitas: water is 100: 3～5: 10～12: 0.5～1: 2.5～3, described stablizer is a divalent metal salt, described dispersion agent is water miscible polymeric surface active agent or polysaccharide compound, and sanitas is phenylformic acid or phenol.
A kind of lightweight foaming cement concrete with the preparation of egg yolk cement concrete foamer, adopt following method to make:
1) with aluminosulfate cement as gelling material, ceramic is as light skeletal, according to cement: ceramic: the quality of water=1: 0.1～1: 0.3～0.6 prepares the cement concrete slurry than mixing and stirring.
2) according to egg yolk: stablizer: dispersion agent: sanitas: the weight proportion of water=100: 3～5: 10～12: 0.5～1: 2.5～3 mixes, and stirs with homogenizer, forms the closed-cell foam of even compact.This foam of getting certain volume adds in the cement concrete slurry of premixing, stirs, and pours into the mould maintenance.
The performance perameter of egg yolk lightweight foaming cement concrete of the present invention is: unit dry weight is 300-800kg/m3, and 28 days ultimate compression strength is 0.6～3.0MPa, and thermal conductivity is 0.06～0.15W/ (m.k).
Beneficial effect of the present invention: as cement blowing agent, raw material is easy to get, and is with low cost with egg yolk, and foam process is simple.Utilize the whipping agent of egg yolk, overcome conventional surfactant as blowing agent stability difference and plant animal protein type whipping agent insufficient raw material, defect of high cost as foaming cement concrete.
(4) embodiment
A kind of egg yolk cement concrete foamer utilizes proteinic foam performance in the egg yolk, and as the composite an amount of stablizer of the base-material of cement blowing agent, dispersion agent and sanitas, thin up is mixed with the cement concrete whipping agent again with egg yolk.Its weight proportion is an egg yolk: stablizer: dispersion agent: sanitas: water=100: 3～5: 10～12: 0.5～1: 2.5～3.
Described stablizer plays stable effect to formed foam, prolongs the time of its froth breaking.Used stablizer is a divalent metal salt, and the contained positively charged ion of divalent metal salt can be Fe
2+, Ca

Described dispersion agent can play the effect that reduces surface tension of liquid, thus lathering property that can the enhanced foaming agent.Used dispersion agent is water miscible polymeric surface active agent or polysaccharide compound.As sulfonated lignin, how to be the sulfonate and formaldehyde condenses, Mierocrystalline cellulose, hydroxymethyl ethyl Mierocrystalline cellulose, Vltra tears, xanthan gum, gum arabic etc.Preferred sulfonated lignin, xanthan gum.
Described sanitas is the material that can prevent microbial spoilage and breeding.As phenylformic acid, phenol etc., preferred phenylformic acid.
The egg yolk cement foaming agent performance that the present invention makes is as follows:
| Numbering | Prescription | Foam expansion | Froth stability |
| 1 | Egg yolk+CaCl 2+ xanthan gum+phenylformic acid | 10 | 3.5 hour |
| 2 | Egg yolk+NiCl 2+ xanthan gum+phenol | 11 | 4 hours |
| 3 | Egg yolk+FeCl 2+ sulfonated lignin+phenol | 12 | 4.5 hour |
| 4 | Egg yolk+NiCl 2+ sulfonated lignin+phenylformic acid | 13 | 4.5 hour |
| 5 | Egg yolk+FeCl 2+ sulfonated lignin+phenylformic acid | 14 | 5 hours |
Note: foam expansion is a lather volume and the ratio of expanding foam solution volume in the table; Froth stability is the foam required time that all disappears.
A kind of lightweight foaming cement concrete with the preparation of egg yolk cement concrete foamer may further comprise the steps:
