Description
Technical field
The invention belongs to foaming agent technical field, and in particular to cement blowing agent.
Background technology
It is existing using flyash, cement as the product such as main material production frame structure non-bearing light cellular partition board and building block
When, it is necessary to foamed using foaming agent.Foaming agent species is a lot, mainly has at present：Rosin soap foaming agent, metallic aluminium powder hair
Infusion, vegetable protein foaming agent, animal protein foaming agent, resin soaps foaming agent, hydrolysis blood glue foaming agent, mahogany acid aluminium hair
Infusion etc.., there is respective defect again in the various existing respective advantages of foaming agent.Rosin soap foaming agent is using a kind of hair earlier
Infusion, is a kind of surfactant produced by saponification for primary raw material with rosin and sodium hydroxid etc., its mainly into
It is divided into the sodium salt of rosin resin, outward appearance is in fawn liquid.Its manufacturing process is simple, and material cost is relatively low, but its energy that foams
Power and foamy body are also poor, are unsuitable for making 700kg/m3Following foamed concrete product.Vegetable protein foaming agent be with
Natural macromolecular material is raw material, the chemical reaction generation through a series of complex, and this foaming agent is light yellow transparent liquid, molten
Yu Shui, it is insensitive to hard water, it is nontoxic, tasteless, it is foaming abundancy, fine and closely woven with excellent foaming capacity, still, due to raw material
Quality it is unstable, cause the foam performance of final products unstable, be suitable only for less occasion and use, thus do not obtain big
Area is promoted.At present, both at home and abroad that it is widely recognized that animal protein foaming agent, it using animal (ox, sheep) keratoprotein is main to be
Raw material, add the industrial chemicals such as a certain amount of sodium hydroxid, hydrochloric acid, magnesium chloride, and heating dissolving, dilution, filtering, high temperature shrink
Form, in crineous viscous liquid, up-to-standard animal protein foaming agent has that gas release is big, foamy body is high, steep that wall is thick,
The advantage such as UNICOM, independence is not good, cheap between good stability, foam time length, foam voids, but animal protein foams
Agent exist major defect be：Foaming capacity, foam stability are poor, and the finished product of traditional product occurs that obvious top is
Clear water, lower part is the situation of foaming agent finished product.Therefore, people have carried out long-term exploration, it is proposed that various technologies
Scheme.Such as Chinese patent literature discloses a kind of animal ingredient concrete foaming agent [application number：200510010184.0], it with
Horn matter is raw material, and horn matter is crushed into big grain of rice size, subsequently into primary first-order equation kettle, adds hydroxide
Receive, be heated up to 70 DEG C, the time be 6 hours, subsequently into secondary response kettle, addition hydrochloric acid, be heated up to 70 DEG C, the time be 3 hours,
Into filter filtering, it is finished product to carry out high temperature dehydration subsequently into concentration tank.Although improving product to a certain extent
Performance, but complex manufacturing technology, are more expensive to manufacture, and only raw material will just expend substantial contribution, and performance be not it is particularly stable,
Still the phenomenons such as not strong foaming capacity, stability difference or layering are likely to occur, existing foaming agent blistering rate is low, foam stability
Difference, the product weight weight being made, low intensity, high cost, it is difficult to meet the market demand.
The content of the invention
It is an object of the invention to provide cement blowing agent, blistering rate is high, foam stabilization good with cement compatibility；Product
Body is light and intensity is high, and consumption is few, low cost；Fire-proof and water-proof performance is good, "dead", energy-conserving and environment-protective and is widely used；Raw material
Easily take, process is simple, it is easy to implement.

The mechanism of action of the silicones polyethers emulsion steeps surfactant to be put in order by changing intramolecule
Arrange close neat between bubble, so as to form the inner layer film of densification so that anti-pressure ability is especially strong, can control air bubble liquid-membrane
Structural stability, make surfactant molecule in the Methodistic distribution of liquid film of bubble, assign the good elasticity of foam and from
Repair ability, so as to reach especially desirable foam stabilizing effect.
The lauryl sodium sulfate is a kind of anion surfactant, soluble in water, its biological degradability>90%,
Lauryl sodium sulfate is added in expanding foam solution as foam stabilizer, greatly strengthen the foaming characteristic of solution and the viscoelastic of foam film
Property, particularly foam stability be improved significantly.
Cement blowing agent of the present invention is good with cement compatibility, and blistering rate is high, foam stabilization, and product body is light, intensity
Height, consumption is few, low cost, and fire prevention, water resistance are good, and "dead", energy-conserving and environment-protective are widely used, using cement, flyash as original
Material, the product such as frame structure non-bearing light cellular partition board, building block for being produced using this foaming agent with being given birth to using existing foaming agent
Production identical product is compared, and the light 35%-40% of body saves foaming agent 35%-40%, low cost 40%-45%.Also one protrusion
Advantage is good with cement compatibility, can be reacted with the Ca2+ in cement, generates insoluble salt, foam stability increase, to product
Intensity improve it is more favourable；Due to adding glutinous rice starch, not only effectively increase the thickness of steep that wall, and with the gluing of cement
Splendid, the inside microcellulor hole support force more Strong for the product that foam is made after being mixed with cement slurry of property, causes product strength big
Width is lifted, and the durability of the veneer such as glutinous rice starch and cement, stone flour, coal ash is longer.
Primary rosin used, high-quality gelatine, NaOH, glutinous rice starch, lauryl sodium sulfate are marketable material,
Raw material easily take, and process is simple, it is easy to implement, the environment friendly light partition wall batten produced using foaming agent of the present invention from
Presentation quality, size, surface density, fracture resistence force, impact resistance, air shrinkage value, single-point hanging force, combustibility and oise insulation factor meet
