Abstract
The invention provides a high-performance viscosity modifier used for a cement-based cementing material. The viscosity modifier is an aqueous solution of a solid-liquid composition, the total mass of the solid-liquid composition is 100 parts, and the solid-liquid composition contains the following raw material components in parts by weight: 65-75 parts of a salt intercalation agent, 10-20 parts of an organic matter intercalation agent, 10-20 parts of a cationic type monomer and 5-15 parts of alkyl phenol polyoxyethylene. The viscosity modifier is the aqueous solution of the solid-liquid composition, the solid solution quantity ratio of the solid-liquid composition in the aqueous solution is 5-8%, and the mixing amount of the viscosity modifier in the cement-based cementing material accounts for 0.6-1.0% of the sum of mass of the cementing material. The viscosity modifier provided by the invention has the advantages that a cationic monomer is adopted for dispersing cement clinker early strength type minerals C3A and C4AF and releasing moisture wrapped by the early strength type minerals in component design; the early strength type minerals are excited, and the cohesiveness is improved; and the micro expansion effect of an early strength type hydration product is equivalent to the increased volume flow rate of the cementing material, and the wrapping property is slightly improved.
Description
Technical field：
The present invention relates to building material field, and in particular to a kind of high-performance viscosity modifier for cement-based gelling material
Agent.
Background technology：
As modern architecture develops to high-rise and complicated form, Steel Bars in Concrete Structure arranges intensive and interstitital texture shape
Changeable, concrete must not only meet construction high fluidity requirement, should also possess good cohesiveness and water-retaining property, and mobility with
Water-retaining property, the mutually contradictory contradiction of cohesiveness index, in order to obtain, homogenieity is good, viscosity appropriate, coagulation is mixed in the new of favorable working performance
Soil, generally by increasing water reducer consumption or taking high water reducing rate type water reducer to obtain the coagulation of flow properties ideal in engineering
Soil, but also it is easily caused concrete appearance isolation excreting water phenomenon.
To eliminate isolation excreting water phenomenon, the rheological parameter of concrete is controlled by adding thickener, air entraining agent, and adjust
The cohesiveness and water-retaining property of the inside of concrete, are most commonly used that cellulose ethers and polyacrylamide thickener to adjust at present
The viscosity of concrete is saved, the bridge effect between thickener family macromolecule polymer and cement granules can form substantial amounts of flocculation knot
Structure, the flocculent structure can consume the Free water in slurry, but its volume is difficult adjustment, and mobility and the more difficult matching of viscosity are flat
Weighing apparatus.Therefore suggestion is using the viscosity modifier of non-adsorbed type, to ensure the action effect of water reducer.
The A of patent CN 104973817 disclose a kind of concrete viscosity suitable for being used with polycarboxylate water-reducer compatibility and adjust
Section agent and preparation method thereof, components in weight percent:Clay stabilizer：0.1~10%；Air entraining agent：0.01~ 5%；Foam stabilizer：
0.001~5%；Thickener：0.001~10%；Water：75~99%.Mixer is first added water to, other components are sufficiently mixed uniformly, open
Open after mixer operates steadily, then slow input, hold material and fully dissolve and stir.
The A of patent CN 104031464 disclose the viscosity modifier of the high concentration dispersion for fine inorganic particles, and it passes through
Assign high concentration dispersion (printing ink composition of the high concentration dispersion of such as fine inorganic particles, work(of fine inorganic particles
Can paste compound or coating compositions) excellent viscosity modifier effect, it is possible to reduce the print steps of manufacture part or base material or
Inconvenience generation in application step, and the high concentration dispersion that the fine inorganic particles comprising the viscosity modifier are provided.Institute
The high concentration dispersion of the fine inorganic particles of viscosity modifier is stated, used as key component, the viscosity modifier is included in molecule knot
There is the product of 2 to 20 phosphoric acid foundation or carboxyl, the product is by with two to six polyalcohols of hydroxyl in structure
Material is introduced with phosphate or complete base and introduce material, with 3:1 to 1:1 hydroxyl introduces material to phosphate or carboxyl introduces material
Material molar ratio reaction is obtained.
The A of patent CN 104479066 disclose a kind of concrete viscosity conditioning agent and preparation method thereof, the viscosity modifier
Obtained by free-radical polymerized by cationic monomer, anionic carboxyl monomer and internal crosslinker, cationic monomer, anion carboxylic
Base monomer, the mol ratio of internal crosslinker are 1：(0.5~5)：(0.01~0.1).The present invention is using cationic monomer, anionic carboxyl
Monomer copolymerization obtains amphiphilic polymers, with obvious anti-poly- electricity matter property, shows preferable thickening property；Add simultaneously in
Crosslinking agent makes to form tridimensional network between viscosity modifier and gelling material particles, concrete disintegration bleeding is greatly reduced and asks
Topic, improves the workability of concrete.
The content of the invention：
Present invention aim at a kind of high-performance viscosity improver for cement-based gelling material of offer.In view of this, this hair
The bright technical problem to be solved is to provide a kind of grasp to be suitable for high-flowing concrete and single conventional polycarboxylic acids diminishing
Agent component cannot solve high fluidity mixture while meeting the auxiliary compounding component of cohesiveness and water-retaining property, build not to thicken
Agent consumes the non-adsorbent viscosity modifier system of Free water, is the difficult point of viscosity modifier multicomponent mixture matched design and crucial institute
.
To achieve the above object, the technical scheme is that:
A kind of high-performance viscosity modifier for cement-based gelling material, it is characterised in that：Described viscosity modifier is solid
The aqueous solution of liquid composition, solid-liquid combination thing gross mass is 100 parts, and the solid-liquid combination thing contains the original of following weight parts component

Example detection result
The high-performance viscosity modifier of example 1,2,3,4 and general thickener are compared, different viscosities are tested respectively and is modified
Agent and general thickener be compound to concrete initial slump/divergence under water reducer and through when the slump/divergence, bleeding
The indexs such as rate.Experiment cement used is new 42.5 ordinary portland cement of China, with reference to GB/8076-2008《Concrete admixture》Test mark
It is accurate.
Different viscosities modifying agent and thickener influence on concrete performance
| Water reducer species | Initial slump/divergence mm | The 1h slumps/divergence mm | Bleeding rate % |
| Ordinary water-reducing agent | 190/580 | 180/500 | 2.2 |
| Ordinary water-reducing agent+thickener | 195/560 | 185/520 | 1.0 |
| Ordinary water-reducing agent+example 1 | 200/580 | 190/540 | 0.9 |
| Ordinary water-reducing agent+example 2 | 205/590 | 195/535 | 0.6 |
| Ordinary water-reducing agent+example 3 | 200/585 | 190/545 | 0.7 |
| Ordinary water-reducing agent+example 4 | 210/595 | 195/540 | 0.6 |
According to indexs such as mobility data, bleeding rates, high-performance viscosity modifier can be observed and compares the mobility of thickener
From the point of view of, initial fluidity is intended to more greatly relative to the blank sample for being provided without the ordinary water-reducing agent that any small powder is compounded, and adds
Thickener would generally reduce initial fluidity；On slump retaining, viscosity modifier whole structure is also significantly better than ordinary water-reducing agent
Blank sample and compounding thickener sample；On bleeding rate, thickener and viscosity modifier can reduce bleeding rate, and viscosity modifier pair
Bleeding improvement is slightly good；In sum, the use of viscosity modifier can not reduce initial fluidity, and significantly improve guarantor and collapse
Property, bleeding rate is synchronously reduced.
