Description
Technical field
The present invention relates to concrete field, specifically a kind of compound water reducer of high-efficiency environment friendly.
Background technology
Concrete, referred to as concrete: refer to be cemented to gathering materials the general designation of the engineered composite material of entirety by Binder Materials.Concrete one word generally said refers to make Binder Materials with cement, and sand, masonry gather materials；Coordinate by a certain percentage with water (additive and admixture can be contained), agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering.
The inorganic coagulation materials such as cement, Calx, Gypsum Fibrosum and water mix and stir and make concrete mix have plasticity；And then condense hardening by chemically and physically chemical action and produce intensity.It is, in general, that drinking water all can meet the requirement of concrete mixing water.In water, acid, alkali, salt and the Organic substance of excess all can produce injurious effects to concrete.Gather materials and do not only have filling effect, and the character such as unit weight, intensity and the deformation of concrete are had a major impact.
Water reducer is a kind of under conditions of maintaining concrete slump constant, can reduce the concrete admixture of mixing water amount.Mostly belong to anion surfactant, have lignosulfonates, naphthalene sulphonate formaldehyde polymer etc..After adding concrete mix, cement granules there is is peptizaiton, its workability can be improved, reduce unit consumption of water, make concrete strength increase and improve durability；Or minimizing unit cement consumption, save cement.
For improving some character of concrete, additive can be added.Having obvious techno-economic effect owing to mixing additive, it is increasingly becoming the indispensable component of concrete.For improving the performance of concrete after the workability of concrete mix or hardening, save cement, also can mix levigate mineral material admixture when concrete-agitating.It is divided into active and inactive two classes.The character of admixture and quantity, affect the intensity of concrete, deformation, the heat of hydration, impermeability and color etc..
Polycarboxylate water-reducer has also stepped into the stage of fast development.This kind of water reducer has many advantages compared with conventional water reducer, low including volume, slump retaining is good, concrete contraction percentage is low, molecular structure is adjustable, the potentiality of high performance are big, do not use the advantages such as formaldehyde in production process, producing plus it and have the feature of environmental protection in application, polycarboxylate water-reducer has become concrete admixture industry developing direction from now on.
Owing to the time of domestic and international application polycarboxylic acids is not the longest, especially in the season that temperature is relatively low or higher, the bubble of concrete surface becomes apparent from, and yet there are no relevant patent and solution that this has been had by document all the time.
Summary of the invention
It is an object of the invention to provide a kind of compound water reducer of high-efficiency environment friendly, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of compound water reducer of high-efficiency environment friendly, includes according to the raw material of weight portion: poly carboxylic acid series water reducer 100-120 part, corrosion inhibitor 8-15 part, defoamer 1-5 part, antifreezing agent 5-16 part, initiator 22-35 part, water 300-350 part；During preparation, poly carboxylic acid series water reducer and water are added reactor, and is warming up to 55 DEG C of stirring 30-45min；It is warming up to 90 DEG C again, adds defoamer, initiator, stir 2-3h；It is cooled to 45 DEG C, adds corrosion inhibitor, antifreezing agent, stir 0.6-0.8h and get final product.
As the further scheme of the present invention: the compound water reducer of described high-efficiency environment friendly, include according to the raw material of weight portion: poly carboxylic acid series water reducer 108-113 part, corrosion inhibitor 10-12 part, defoamer 2-4 part, antifreezing agent 10-11 part, initiator 28-29 part, water 320-330 part.
As the further scheme of the present invention: the compound water reducer of described high-efficiency environment friendly, include according to the raw material of weight portion: poly carboxylic acid series water reducer 110.5 parts, corrosion inhibitor 11 parts, defoamer 3 parts, antifreezing agent 10.5 parts, initiator 28.5 parts, 325 parts of water.
As the further scheme of the present invention: described initiator uses potassium peroxydisulfate.
As the further scheme of the present invention: described corrosion inhibitor uses JK-H2O (A) compounded amino alcohol reinforcing steel bar corrosion inhibitor.
As the further scheme of the present invention: described defoamer uses emulsified silicone oil.
Compared with prior art, the invention has the beneficial effects as follows:
In the present invention, initiator is used for causing alkenes, the radical polymerization of double vinyl monomer and copolymerization it can also be used to the crosslinking curing of unsaturated polyester (UP) and high molecular crosslink react.Polycarboxylate high performance water-reducing agent (liquid) is to be the third generation high-performance water reducing agent grown up after the ordinary water-reducing agent of representative and the high efficiency water reducing agent with naphthalene system as representative continue wood calcium, is at present forefront, scientific and technological content is the highest, application prospect is best, combination property is optimum a kind of high efficiency water reducing agent the most in the world.PC polycarboxylate high performance water-reducing agent is to represent the water reducer product that world today's technology content is leading.Through showing with similar products at home and abroad Performance comparision, PC polycarboxylate high performance water-reducing agent has all reached current international most advanced level in terms of technical performance index, cost performance.Corrosion inhibitor uses JK-H2O (A) compounded amino alcohol reinforcing steel bar corrosion inhibitor；This product does not contains calcium nitrite.Based on modified amido alcohol complex technique, should be composited through science coupling by dispersing molecule, the resistance rust multiple macromolecule such as molecule, anticorrosion molecule.Obstruct due to bubble, make free evaporation of water route in concrete mix become tortuous, tiny, dispersion, thus change quantity and the characteristic of capillary tube, make cement granules be sufficiently humidified so as to, hydrated cementitious is abundant, hydrated product is evenly distributed, and the seriality of concrete inner structure and uniformity strengthen, and aperture refines, defect reduces, the activation of suppression Cl, so that the infiltration of chloride ion or diffusion weaken significantly, slow down and cause steel bar corrosion.Defoamer uses emulsified silicone oil, has chemical stability, heat-resisting tolerance to cold, weather resisteant, lubricity, hydrophobicity and the low surface tension of excellence, harmless to human non-toxic so that it is to be widely used in personal nursing, food production, fermentation industry etc..Antifreezing agent can prevent in material moisture to freeze at low temperatures, can reduce the freezing point in concrete mix, and the freezing up produced that prevents from constructing under subzero temperature in the winter time destroys, it is ensured that the normal construction of concrete under subzero temperature.
Concrete prepared by the compound water reducer of high-efficiency environment friendly using the present invention, and water-reducing rate is higher, has been above more than 30%, reduces the cost of water reducer, and concrete 's air-containing is lower, it is adaptable to the season that temperature is higher or lower.
