Description
Technical field
The present invention relates to the whipping agent technical field, especially relate to a kind of cement blowing agent and preparation technology thereof.
Background technology
The whipping agent kind that is applied in the foamed concrete is a lot, mainly contains at present: rosined soap class whipping agent, metallic aluminium powder whipping agent, vegetable-protein whipping agent, animal protein foaming agent, sodium resinate class whipping agent, hydrolysis blood glue whipping agent, mahogany acid aluminium whipping agent etc.There is defective separately again in the existing advantage separately of various whipping agents.The rosined soap whipping agent is to use a kind of whipping agent early, is to be main raw material with rosin and sodium hydroxide etc., and through a kind of tensio-active agent that saponification reaction is produced, its main component is the sodium salt of Gum Rosin, and outward appearance is light tan liquid.Its manufacturing process is simple, and material cost is lower, but its foaming power and foamy body are also relatively poor, is unsuitable for making the following foamed concrete goods of 700kg/m3.The vegetable-protein whipping agent is to be raw material with the natural macromolecular material, through the chemical reaction generation of a series of complexity.This whipping agent is light yellow transparent liquid, and is water-soluble, insensitive to hard water, nontoxic, tasteless, has excellent foaming power, and foam is abundant, fine and closely woven.But, owing to raw-material quality instability, cause the foam performance instability of the finished product, only be suitable for less occasion and use, thereby do not obtain the big area popularization.What extensively approve both at home and abroad at present, is animal protein foaming agent.Animal protein foaming agent is to be main raw material(s) with animal (ox, sheep) keratoprotein, adds industrial chemicals such as a certain amount of sodium hydroxide, hydrochloric acid, magnesium chloride, and the dissolving of heating, dilution, filtration, high temperature shrink and forms, and are the dun viscous liquid.Up-to-standard animal protein foaming agent has advantages such as gas release is big, foamy body is high, longer duration, is extensive use of in industrialized countries such as Japan, the U.S..As whipping agent, it has, and foam expansion height, bubble wall thickness, good stability, foam time are long, advantages such as UNICOM, independence be not good, cheap between the foam voids.
The major defect that above-mentioned animal protein foaming agent exists is: foaming power, froth stability are relatively poor, and it is clear water that tangible top can appear in the finished product of traditional product, and the lower section is the situation of whipping agent finished product.For this reason, people have carried out long-term exploration, have proposed various technical schemes.For example Chinese patent literature discloses a kind of animal ingredient concrete foaming agent [application number: 200510010184.0], it is a raw material with horn matter, horn matter is crushed to big grain of rice size, enter the primary first-order equation still then, add sodium hydroxide, heat to 70 ℃, time be 6 hours, enter the secondary reaction still then, add hydrochloric acid, heat to 70 ℃, time be 3 hours, enter filter and filter, enter concentration tank then and carry out high temperature dehydration and be finished product.The somebody has invented a kind of egg yolk cement concrete foamer and lightweight foaming cement concrete [application number: 200710014512.3], and it adopts following method to make: 1) with cement: ceramic: water prepares the cement concrete slurry by the certain mass ratio mixing and stirring.2) with egg yolk: stablizer: dispersion agent: sanitas: water mixes by certain mass ratio, forms the closed-cell foam of even compact.This foam of getting certain volume adds in the cement concrete slurry, stirs, and pours into the mould maintenance.As cement blowing agent, raw material is easy to get, and is with low cost with egg yolk in the present invention, and foam process is simple, has overcome conventional surfactant poor stability and plant animal protein type whipping agent insufficient raw material and defect of high cost.
Though technique scheme has improved product performance to a certain extent, complex manufacturing technology, the manufacturing cost height, the light starting material just will expend substantial contribution.And its performance is not stable especially, phenomenons such as foaming power is not strong, poor stability, layering still may occur.Therefore, await further improving.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of product performance stable, foaming power is strong, and production cost is lower, the cement blowing agent of problems such as layering can not occur; Solved that the existing foaming power of prior art is strong, poor stability, layering easily, production cost high-technology problem.
Another object of the present invention is at the problems referred to above, provides a kind of easy to implement, and operation is simple, the cement blowing agent preparation technology that starting material are easy to obtain; Solved existing in prior technology complete processing complexity, the technical problem that is difficult to carry out etc.
For achieving the above object, the present invention has adopted following technical proposal: this cement blowing agent is characterized in that component that this whipping agent comprises and weight percentage thereof are sodium hydroxide 1.0%～5.0%; Rosin 2.0%～10.0%; Gelatine 2.0%～10.0%; Starch 0.5%～2.5%; Trolamine 0.5%～2.0%; Surplus is a water.
The present invention has creatively added starch, because the adding of starch makes uniform in foaming, nothing precipitation, the concentration of whipping agent, the denseness of whipping agent good.Phenomenons such as the foaming power that exists in the prior art is not strong, poor stability, layering have been overcome effectively.Starch has not only been avoided the appearance of demixing phenomenon, can increase viscosity simultaneously, further promotes foaming effect.Trolamine is used for metal cutting, cooling, the acid-base neutralisation agent in antirust, the cosmetic industry, the emulsifying agent of metal processing, the grinding aid in the cement, the hardening accelerator in the concrete construction.Add the trolamine effect among the present invention and be and improve concrete morning of the epistasis of producing and foam stability.
