Abstract
The invention discloses a kind of novel concrete additive, raw material compositions are as follows: sodium sulfocyanate: 38-56 parts；Acrylamide: 5-9 parts；Talcum powder: 11-16 parts；Diatomite: 8-13 parts；Non- villaumite: 6-10 parts；In win polyalcohol amine: 3-6 parts；Calcium stearate: 10-15 parts；Crosslinking agent: 2-5 parts；Initiator: 1-5 parts；Above-mentioned number is mass fraction；It further include 2-6 parts of water-reducing agent.The present invention can play the performance of the additive well in winter, it will not be low and impacted because of temperature, temperature after cement plus water stirring in subzero left and right can freeze, and it is longer to be unable to get required stability or firm time, and existing calcium chloride is then mixed when there are these problems, but it is corrosive mixed with the concrete of calcium chloride, but normal concrete when its setting rate, compression strength are 10C is incomparable；But non-villaumite combination sodium sulfocyanate can be used under cold, warm and hot weather.
Description
Technical field
The present invention relates to a kind of additive, especially a kind of novel concrete additive.
Background technique
With the continuous development of society, every technology is also being continuously improved, and the requirement of cement industry is also increasingly
Height, cement additive have many advantages, such as it is energy saving, reduce cost, improve cement product quality and its yield, at home
It generally uses outside；High-performance cement additive is a kind of synthetics applied in manufacture of cement, acts on cement mill
On to improve yield and increase efficiency, and improve cement performance, quality, the storage of cement, handling condition etc., final goal is
It improves the economy of cement manufacturing industry and promotes the profitability of productivity and enterprise, but existing additive only increases one
A little quick-dryings or the performance of enhancing, but there is no consider cement since some compounds can not play correlation to weather problems at low temperature
Effect.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, provide one kind is not influenced by weather temperature
And the novel concrete additive of properties of product can be played well.
In order to solve the above technical problems, the present invention provides a kind of novel concrete additive, which is characterized in that its raw material composition
Are as follows:
Sodium sulfocyanate: 38-56 parts；
Acrylamide: 5-9 parts；
Talcum powder: 11-16 parts；
Diatomite: 8-13 parts；
Non- villaumite: 6-10 parts；
In win polyalcohol amine: 3-6 parts；
Calcium stearate: 10-15 parts；
Crosslinking agent: 2-5 parts；
Initiator: 1-5 parts；
Above-mentioned number is mass fraction.
A kind of novel concrete additive above-mentioned, which is characterized in that further include 2-6 parts of water-reducing agent.
A kind of novel concrete additive above-mentioned, which is characterized in that the mass fraction of the sodium sulfocyanate is 49 parts, propylene
The mass fraction of amide is 7 parts.
A kind of novel concrete additive above-mentioned, which is characterized in that the mass fraction of the talcum powder is 13 parts, diatomite
Mass fraction be 9.5 parts.
A kind of novel concrete additive above-mentioned, which is characterized in that the mass fraction of the non-villaumite is 9 parts, in win it is poly-
The mass fraction for closing hydramine is 4 parts.
A kind of novel concrete additive above-mentioned, which is characterized in that the mass fraction of the calcium stearate is 14 parts.
A kind of novel concrete additive above-mentioned, which is characterized in that the crosslinking agent includes outside cross-linking agent and internal crosslinker.
A kind of novel concrete additive above-mentioned, which is characterized in that the initiator is organic peroxide evocating agent.
Advantageous effects of the invention: the present invention can play the performance of the additive well in winter,
Will not be low and impacted because of temperature, the temperature after cement plus water stirring in subzero left and right can freeze, and be unable to get required
Stability or firm time it is longer, and it is existing then mix calcium chloride when there are these problems, but mixed with the coagulation of calcium chloride
Soil is corrosive, but normal concrete when its setting rate, compression strength are 10C is incomparable；But non-villaumite knot
Close sodium sulfocyanate can be used under cold, warm and hot weather.
Specific embodiment
Below with reference to embodiment for clearly illustrating technical solution of the present invention, and it cannot be used as a limitation and limit this hair
Bright protection scope.
A kind of novel concrete additive, raw material composition are as follows:
Sodium sulfocyanate: 38-56 parts；
Acrylamide: 5-9 parts；
Talcum powder: 11-16 parts；
Diatomite: 8-13 parts；
Non- villaumite: 6-10 parts；
In win polyalcohol amine: 3-6 parts；
Calcium stearate: 10-15 parts；
Crosslinking agent: 2-5 parts；
Initiator: 1-5 parts；
Above-mentioned number is mass fraction.
It preferably, further include 2-6 parts of water-reducing agent.
Further, the mass fraction of the sodium sulfocyanate is 48-50 parts, and the mass fraction of acrylamide is 6-8 parts；Institute
The mass fraction for stating talcum powder is 13-14 parts, and the mass fraction of diatomite is 9-10 parts；The mass fraction of the non-villaumite is 8-
9 parts, in win polyalcohol amine mass fraction be 3-4；The mass fraction of the calcium stearate is 12-15 parts.
Further, the mass fraction of the sodium sulfocyanate is 49 parts, and the mass fraction of acrylamide is 7 parts；It is described
The mass fraction of talcum powder is 13 parts, and the mass fraction of diatomite is 9.5 parts；The mass fraction of the non-villaumite be 9 parts, in win
The mass fraction of polyalcohol amine is 4 parts；The mass fraction of the calcium stearate is 14 parts, and above-mentioned formula sodium sulfocyanate occupies this and adds
Add the 38.8% of agent, attribute of performance is optimal with respect to other proportions.
Preferably, the crosslinking agent includes outside cross-linking agent and internal crosslinker, and can be allowed inside and outside cement in this way can be good
