Abstract
The present invention discloses a modified polycarboxylate powder superplasticizer dedicated to flowable mortar. The superplasticizer comprises the following components by weight: 90.0-98.0% of a polycarboxylate original powder, 0.5-5.0% of superfine talc, 0.25-1.0% of an anti-adsorbent, 0.03-0.08% of high-viscosity biosynthesis collagen, 0.3-0.5% of fibril synthesized pulp, and 0.5-2.0% of retarder with high degree of polymerization. Through the above-described manner, the modified polycarboxylate powder superplasticizer dedicated to flowable mortar provided by the present invention with the help of physical complex and efficient, low-dosage additive improves the flowability of polycarboxylate superplasticizer, improves the spreading area of flowable mortar, extends the release time of the polycarboxylate force, maintains good degree of construction work, improves work efficiency, and improves the quality of construction.
Description
Technical field
The present invention relates to concrete field, particularly relate to a kind of modified polycarboxylic acid powder water reducer be exclusively used in mobility mortar.
Background technology
General polycarboxylate water-reducer is used in the mortar of mobility, and its time point played a role has difference because of the difference of material.In other words, the time that water reducer plays maximum utility is different, and what have can play a role completely at 15 seconds, and flowing property reaches best, and what have needs prolongation churning time to 1 minute, just can reach best flow effect.Although volume is identical, the field of application will be different.Particularly, along with social progress, the price of labour power is more and more higher, and simple dependence has manually removed a few thing, in efficiency with all can not well be ensured qualitatively.This just needs to use mechanized construction, and that just must supporting suitable material, and then requires that the additive of preparation performance excellence is to meet processing requirement.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of modified polycarboxylic acid powder water reducer be exclusively used in mobility mortar, pass through physical compounding, by effectively, the auxiliary agent that volume is low improves the flowing property of polycarboxylate water-reducer, improve the spreading area of flowing mortar, extend the time of releasing of polycarboxylate water-reducer reactive force, keep good construction working degree, improve working efficiency, perfect construction quality, pass through modified additive, poly carboxylic acid powder water reducer is made to increase water-keeping thickening effect, the tolerance of water reducer water can be improved, reduce bleeding, segregation, improve the self-healing performance of cement slurry.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of modified polycarboxylic acid powder water reducer be exclusively used in mobility mortar, it is characterized in that, comprise the component of following mass percent:
The former powder 90.0-98.0% of polycarboxylate water-reducer;
Superfine talcum powder 0.5-5.0%;
Anti-sorbent material 0.25-1.0%;
High viscosity biosynthesizing collagen 0.03-0.08%;
Protofibril synthetic paper-pulp 0.3-0.5%;
High-polymerization degree retardant 0.5-2.0%.
In a preferred embodiment of the present invention, the fineness of described superfine talcum powder is 600-1200 order.
In a preferred embodiment of the present invention, the component that described high viscosity biosynthesizing collagen comprises has: welan gum, high-viscosity cellulose ether and bone collagen.
In a preferred embodiment of the present invention, the low viscous fibrous material that described protofibril synthetic paper-pulp adopts high dispersive technology to obtain, its viscosity is between 5-300mPa.s.
In a preferred embodiment of the present invention, the component that described high-polymerization degree retardant comprises has: if organic synthesis has the polymkeric substance of water-reducing property, white sugar and Sunmorl N 60S
The invention has the beneficial effects as follows: the modified polycarboxylic acid powder water reducer be exclusively used in mobility mortar of the present invention, pass through physical compounding, by effectively, the auxiliary agent that volume is low improves the flowing property of polycarboxylate water-reducer, improve the spreading area of flowing mortar, extend the time of releasing of polycarboxylate water-reducer reactive force, keep good construction working degree, improve working efficiency, perfect construction quality, pass through modified additive, poly carboxylic acid powder water reducer is made to increase water-keeping thickening effect, the tolerance of water reducer water can be improved, reduce bleeding, segregation, improve the self-healing performance of cement slurry.
