Abstract

The invention belongs to the field of building materials, it is proposed a kind of lignin-base foam concrete foamer, raw material includes: 15-25 parts of tap water by weight, 25% 15-25 parts of sodium hydroxide solution, 5-10 parts of glyoxal, 1-5 parts of sodium carboxymethylcellulose, 1-5 parts of Polyacrylate Emulsion, 5-10 parts of sodium vinyl sulfonate, 1-5 parts of sodium stearyl sulfate, 1-5 parts of sodium sulfate of polyethenoxy ether of fatty alcohol;Material workability is good, and foam is fine and smooth uniformly, and stability is high;Product is made with certain tensile property, long service life;Raw material sources are abundant, cheap, low manufacture cost.

Description

A kind of lignin-base foam concrete foamer
Technical field
The invention belongs to the field of building materials, and in particular to a kind of lignin-base foam concrete foamer.
Background technique
Foamed concrete is that foaming agent is mechanically sufficiently foamed by the foamed system of foaming machine, and by foam It is uniformly mixed with cement slurry, then cast-in-place construction or mold molding is carried out by the pumping system of foaming machine, through natural curing institute A kind of novel light insulation material containing a large amount of sealed porositys of formation;With the stirring such as foaming agent, cement, flyash, mountain flour At the polymer of double set continuous structures of organic binder, include uniform stomata;Slope, ground insulating pad are looked for for roof heat insulation Layer turns over the filling of beam foundation pit, wall pouring etc..
Domestic common foaming agent is mainly based on rosinous material or animal/vegetable protein at present, but properties of product difference It is larger.Rosinous material is cheap, but performance is unstable, influenced by environmental temperature.And the performance phase of animal/vegetable protein To stablizing and pure natural pollution-free, but frothing percentage is not high, and price is also partially expensive.
Therefore, the high-performance foaming agent that a kind of foaming coefficient is high, performance is stable and pollution is small is prepared, is that current foam is mixed Bottleneck problem urgently to be resolved in solidifying soil development.
Summary of the invention
In order to overcome the deficiencies of the prior art, the high-performance foaming that a kind of foaming coefficient is high, performance is stable and pollution is small is prepared Agent, the present invention propose a kind of lignin-base foam concrete foamer.
Technical solution
For achieving the above object, the present invention provides following technical schemes:
A kind of lignin-base foam concrete foamer, raw material include: 15-25 parts of tap water by weight, and 25% sodium hydroxide is molten 15-25 parts of liquid, 5-10 parts of glyoxal, 1-5 parts of sodium carboxymethylcellulose, 1-5 parts of Polyacrylate Emulsion, vinyl sulfonic acid 5-10 parts of sodium, 1-5 parts of sodium stearyl sulfate, 1-5 parts of sodium sulfate of polyethenoxy ether of fatty alcohol.
Beneficial effect of the invention is:
1. material workability is good, foam is fine and smooth uniformly, and stability is high.
2. product is made with certain tensile property, long service life.
3. raw material sources are abundant, cheap, low manufacture cost.
Specific embodiment
